INFORMATION PLEASE

^itor:

I purchased a Gorilla Banana Printer for
my CoCo and would like to know if anyone
knows of a screen dump program I can use
with it. By the way, anyone interested in
buying a Banand Printer should make sure
the printer is sent with a serial interface
unless you have a parallel/ serial converter.
The Banana is a fine printer but if you don't
specify a serial interface when ordering you
may be disappointed when it arrives and end
up spending at least $60 for an interface
cable, like me. Write: 167 18 Polo Road,
61081.

Editor:

1 have some questions about the machine
language listings in your Rainbow On Tapes.

How do you load the listing so that it can
be displayed on the screen? How do you
make changes to the listing? How can you
print out the listing to a printer?

I have EDTASM+ from Radio Shack.

Les Dunni
Milton, FL

Editor's Note:

You must use a disassembler such
as the one available in ZBUG,

AUTOSTART ACTION

Editor:

Is there a way to make a program RUN
automatically once it is loaded from tape?

Harry A, Thayer
Ravena. NY

Editor's Note:
See Steve Abrams' tetter.

Editor:

1 would like you or your readers help! 1
would like to know how to autostart Extend-
ed BASIC or machine language programs
loaded from tape or disk.

There is so much information gnd helpful
tips in your publication that I thought you or
your readers might solve this problem for
me?

Richard A. Thomas
Ferndale, WA

Editor's Note:
See the follolving letter.

Editor:

Recently there have been a rash of new
programs on disk which when LOADMed^
perform their own start without having to
type in EXEC. Also some of these programs
start again at the beginning when the R ESET
button is pushed.

How can this be accomplished before the
program even starts?

Steve Abrams
San Francisco, CA

Editor's Note:

By loading a small program into
low memory you can force a program
to autostart by modifying certain
memory locations. You can also force
a program to restart upon [RESET]
by the same method. See theRainbow
"^Memory Map" and see if you can
identify these addresses. You may
start at $9F.

Editor:

I am a recent proud owner of a CoCo 2
Extended basic computer. At the time of
purchase your magazine was recommended
to me. 1 have a copy of the January 1984
issue and it is better than I had anticipated.

One of the things ( wanted to do with my
new CoCo is to place on tape 7 generations
of my family tree with all the data about each
generation. At present I have about 90 to 96
direct ancestors and others to record,

1 am having problems finding a program
for genealogy. Would you know of any pro-

gram that would handle this much informa-
tion and where 1 could obtain it?

La Verne Ashabranner
Jeffersonville, Ind.

Editor's Note:

See All in the Family Tree^ February
1984, Page 78. Also WeSt Bay Com-
pany has a genealogy program called
Roots*

SOME DO'S AND DONTS

Editor:

I am 13 and have a 64K CoCo. I enjoy
your magazine a lot and espegially enjoy
"Letters to Rainbow." Tm in a computer
club at school and recently several cOmpu*
ters have broken down. They have blamed
this on the peeks and pokes of our programs.
So, we have three angry teachers and some
poor kids who are being punished for it. I
told them that it was impossible for the pro-
gram to hurt the computer. (So I live dan-
gerously.) But being that Vm a kid, I guess
they started telling me how wrong 1 was.

1 have read a statement somewhere about
software hurting hardware but cant find
that particular issue to prove my story is
true. Who s right?

Can I use peeks and pokes safely from
now on without worrying aboiit hurting the
computer?

Dylan Krider
Houston, TX

Editor's Note:

Dylan, the computer will not be
damaged by any command you type
in or by any program you run, eveh if
there are errors. One thing that will
wreck a CoCo is plugging or unplug-
ging cartridges or disk controllers
(anything that goes into the cartridge
slot) with the CoCo turned on. Always
switch the CoCo off before changing
cartridges.

Editor:

I have a 1.0"D" board, upgraded to 32K. 1
recently bought a Radio Shack DWP-210.
To get it to work, I needed to install a new
Color Basic I.I chip, #8040364 A. It takes
about 1 0 minutes to pop out the original and
put in the new chip.

Does anyone know how to get the DWP-
210 to underline using the Telewriter word
processor?

Write me: Route 2, Box 577A, 56367.

LOST AND FOUND

Editor:

Over the paSt couple of years, 1 Ve gairied
quite a large stockpile of information about
CoCo products — more information than I
can afford to take advantage of. Tm on the
mailing lists of several large CdCo software
companies, so I have a lot of new product
inforrnation coming in at regular intervals.
Td like to extend an invitation to kainbow
readers, especially those who may be new to
the CoCo Community. If anyone is looking
for a certain type of program and theyVe
had no success finding it so far, they can
write me at 1801 I7th Avenue, 49858. Til try
lo answer any letters as quickly as possible. 1
feel that CoCo is a great machine arid there
are a lot of great prod ucts available — hope-
fully I can help people find some of them.

OH, MUMMY

Editor:

Foi- all of you Adventure buffs who are
still having trouble in Pyramid ditid Raaka-
Tu, I have a few major tips for you. In
Pyramid, no one can seem to find the Pha-
roah's chest. It is deep within the maze, past
the pit. This information has been printed
before, yet the person always would leave
oiit one vital piece of information. When
you get to the pit in the maze, go east one
more time, and then go northwest, then you
should see the words "Dead End." This is
where the chest is. In order to get it, the
mummy has to have previously takeh some
of your treasures. If he has, you will see your
treasures, and the chest. If you do not know

how to get the mummy to take yoiir trea-
sures, or you cannot get to the pit, write the,
and I will tell you.

In Raaka-Tu^^hen you leavfe the temple,
you only have 25 points, yet you have all of
the treasures. To Solve this, when you leave
the temple, go west twice, and then north
three times, then press "Score," and yoii
have 50 points. If you can't find any of the
treasures; or just need to find one rtiore, just
Write me at: 1 10 Ashley Drive, 29631.

John Ailen
Clemson, SC

Editor:

1 have reached the 220 points for PyrarHid
which was quite a challenge. I can see why
some people are running into a lot of prob-
lem3. Any questions you have, I would be
glad to answer, 1058 E. 9th Avenue, 85204.

Judy Fodness
Mesa, AZ

Editor:

I have helpful hints to solving Stdlarh. I
have answers to cjuestions such as! How do
you get the red key? How dp you get. the
green kfey? How do you stop wandering?
How do you get out? If yoii need any help on
Bedlam, send a self-addressed stampecj enve-
lope to: 1450 Picadilly Street, 23513^ t)ne
dollar handling appreciated. I will also in-
clude a map of Bedlam.

Editor-
Add my name to the list of people around
the reading area in saying, ^"7 hanks, for a
great magazine!" You and your staff have
convinced my friends and me that the Color
Computer is not only the best computer, but
also the one with the best information
source, the Rainbow\

We are growing by the years with software
and hardware additions and are looking
forward to growing with your magazine in
knowledge and understanding of this fasci-
nating world of computers!
May life be one BIG Rainbow for us all!

Editor:

I really enjoy your magazine. I have com-
pared the three major magazines available
for the CoCo and yours is tops.

1 would like to point out that I've had no
problems obtaining these programs, but I
consider your magazine of such high quality
and low price that 1 feel obligated to "pay "
for the convenience of having the programs
sent to my door. 1 hope others (pirates) will
recognize the true value of this service and
aid you in being able to continue providing
such quality to the CoCo Community at
such a great price. All those programs plus a
great magazine complete with documenta-
tion. Your efforts are appreciated!

Editor:

1 would like to compliment you on a fine
magazine. In fact, my subscription to one of
your competitors is being replaced with a
subscription to Rainbow this year. It was a
pleasant surprise to find so much support
available for the CoCo after purchasing
what was going to be '^just something to play
with."

Again, thanks for an excellent magazine
and all the help it has given me.

magazine for the CoCo. Thanks!

Keep up the great work and thanks for a

HINTS AND TIPS

Editor:

1 am writing this letter to you because I
want to praise this fine publication that you
have. This is the second year that I have
subscribed to your excellent magazine. 1 also
want to say that 1 like this fine computer that
1 am writing this letter on. The TRS-80
Color Computer is a machine that is not as
well praised as it should be. The 6809
microprocessor is a very powerful little beast
that should not be underestimated. My sys-
tem consists of a 64K Color Computer and a
disk drive. I have a lot of excitement for the
future of this computer since OS-9 was
released by Radio Shack. It shows that
Radio Shack cares a lot for the future of the
Color Computer. Since 1 bought the com-
puter back in 1982 I have seen it expand and
grow to a very well-supported computer.
Even Radio Shack has begun to expand its
support for its little computer.

I would like to share a couple of peeks and
pokes I have discovered.

We have encountered a situation you
might want to pass along to your readers. At
least two brands of wireless telephones will
cause the Amdek disk drives to speed up and
crash. If you have portable phones in your
house you might want to avoid their use
when your Amdek drive is being used. Evi-
dently the R.F. signal being generated by the
phones can affect the speed of the drives.

INTERESTING INDEX

Editor-
May 1 make a suggestion to your readers?
Tape an index card on each issue of the
Rainbow and write on it the tips, hints,
ideas, and articles of interest to you and note
the page numbers as well. As your collection
grows, it will be vastly valuable and easy to
find any item you wish to recall. But be
smart — if you read an article about a disk
drive or for a printer and you think it would
be great, except you don't have a disk drive
or a printer, note it anyway. Someday you
will, and you'll wonder where (what month
and year) was that article about banner
headlines or "Gosh, wasn't there a POKE to
prevent headcrashes?"

Editor:

How would you like a disk file to appear
on the directory, but nobody except you can
load it? To do this, save your file as follows:
SA VE "FILE"-¥CHR$(I43). The file will
appear normally on the directory, but at-
tempts to LOAD "FILE" will give you a?NE
ERROR . To load the file, use LOA D "FILE''
+CHR$(143). I'm sure you can find varia-
tions on this process.

1 Would like to pass on t)iis information to
the people who have been having problems
with their coniputers shutting off on them.

The current sensing resistor R66 in the
"D" board J3 OHM should be replaced
with a high quality resistor. This particujar
type of resistor has the leads primped to the
resistive wire and is prone to open. 1 was
experiencing problems with my computer
quitting. Turning it off and on would sopie-
tini^s correct it for a while. After 1 replaced it
with a welcj-l?onded type of resistor ail rny
problems went away.

BOUQUETS AND BRICKBATS

ptfitor:

I want to say some kind words about a few
of your advertisers. In December 1 ordered
from both Computer Plus and MichTron.
All 1 can say is that if ?very advertiser con-
ducts business like them, there are some
mighty satisfied CoCo users out here. Like-
wise, for a non-mail order company. The
Program Store in Eatontown, N.J. is out-
standing. The managers are super nice and
gladly let customers try the programs before
buying. Even though I normally pay full list
for what I buy and have to drive 65 miles tp
get there, 1 Ve saved fnyself that "ripped-ofP
feeling many times by trying before buying,
if all the Program Stores operate this way
theyVe well worth the visit.

Thanks again for an excellent magazine.

Editor:

1 have recently purchased Complete Per-
sonal Accountant software by Futu rehouse
on the recommendation of Rainbow and 1
am reasonably happy with the product even
tliough the cost is quite high gonnp^red to
other similar utilities.

The reason for writing this letter is to
point out tp others, that to receive any soft-
ware support for this product you must send
in an additional $20. In fact, if you call the
company they will speak to you if you giv?
them your VISA number.

I personally have not tried to call them but
their literature statps that it is so.

This $20 fee is supposed to cover any
future updates or additions to the product
which is purported to be sent free pf charge.

I doubt that a company that charges for
software support is about to send an update
free from any further charges.

I would be interested in hearirig of any
other experiences with this company.

Lawrence B. Snyder
Norristown, PA

Editor:

We would like to address our policy of
charging $20 for technical phone support to
the end users of pur Complete Personal
Accountant, First, it is important to note
that not everyone who buys a home finance
package needs technical support. As a mat-

ter of fact, less that 25 percent of our custo-
mers inquire about our program. Keeping
this in mind, we thought it would be unfair
to incorporate the cost of technical support
in the price of thp package. Our technical
support staff are all full-time, paid employees
who do nothing but ciistomer support work
all day. There are many companies which
charge for their technical s\ipport programs.

If we were to include the cost of technical
support into the price of the CPA, the pack-
age would cost $99.95! Instead, we thought
it would be much more fair to charge $79.95
and let the end user decid? if he or she
wanted tp pay for technical support.

I enjoy yopr great rnagazinc and was glad
to hear that it is now sent second class mail. 1
was afraid sometimes that our mail per-
sonnel found it so dynamite that they were
not going to give it up.

It would be really great if electronics
stores would start to advertise in your maga-
zine. Tm in a Computer Club' and we are
presently making our own modems. Some of
the parts are not carried by Radio Shack and
are hard to get. Also, some of the hardvyare
projects in your magazine, like the "Cheap-
stick" (Feb. 1984, Page 186), are great tod,
and would be even greater if fmding all the
right parts was not so difficult.

my confidence, 1 upgraded my CoCo to 64K.

PRINT #-2,

Thanks to the installation of some new equipment at
our printer's, last month's issue of the Rainbow was a
little later than usual. That was good and bad.
The good part was that I was able to fill the first couple of
paragraphs of this space with some news from R AlNBOWfest-
Long Beach; something 1 would not have been able to do
had the printer handled the Rainbow on time as is usually
the case.

The bad part of it all is that we were a tad late with last
month's issue and this one arrives a couple of days less than
the full month between issues. What happened? We can all
sympathize with our printer: They bought a new piece of
computer equipment that would make things "lots easier"
for them — but there were a few interfacing problems.

How jnany timeis have we all heard that one? Oh well, the
problems seem to h^ve been licked as of this writing and we
are back on schedule again.

And, yes, you did get a chance to read a little bit about
Long Beach last month, but this month ] get the opportunity
to tell you even more about the show. It was really a great
one! 1 think everyone, just about, had a fine time and the
spirit of CoCo Community was very much in evidence.

My special thanks to Bob Albrecht, who was our keynote speaker at the CoCo Community
Breakfast Saturday morning. And what a surprise — it was also Bob*s birthday. How did 1 find out?
Well, Don Inman told me. Bob was trying to keep it a deep secret. That didn't last long, either. Nor
did the special cheesecake (for the big cheese) we had whipped up for Bob at the last minute.

1 think the greatest thing about R AIN BO Wfest is that it is a lot of fun for all. By the time you read
this, our R AINBOWfest-New Brunswick will be history, too, ahd if you havp not been to one of our
shows, there's only one chance left — the Chicago show June 22-24 at the Hyatt-Regpncy Woodfield.
That was the site of CoCo*s Very First Show a year ago. So, do plan to join us then if you have not
been with us already. Or, as we say here in the South, "Do come again!"

By the way, the question 1 get asked most often at R AlNBOWfests is whether we will be back next
year. Although at this writing the dates are not 100 percent firm, we dp plan to do another series of
RAINBOWfests in the 1984-85 "season."

Tentative pl^ns call for a show in the Eastern part of the United States in the fall; a show in
California during the winter and a return to Chicago in the spring — somewhat earlier than this
year's Chicago show. There will be details (we hope) about sites and dates next month.

One of the things 1 like the most about RAlNBOWfest is the opportunity to talk at some length
with other members of the CoCo Community who attend each show. Long Beach was np exception;
and one of the questions 1 was asked is one 1 would like to share with you for your input.

The issue was arcade-type games and the subject was whether 1 believed "winning" was an
important issue that might be lacking from these games. Here's the thesis:

With most traditional games (board games, card games, simulation games and the like, whether
written for a computer or not) the player has an opportunity to win the game. With most arcade
games this is not the case — all you can do is lose.

Think about it for a minute. You can play a game for hours and hours, mount up scores that are
higher and higher (as our "Scoreboard" feature will attest), but, in the end, you always "lose" — you
are always destroyed by the game.

The discussion I had in Long Beach centered around the fact that it might be better that the player
should, at some point, be able to "win" the game — that the game would, at some point, say "I lose
and you win."

My point was that this would certainly decrease the playability of a game. Once the player won, all
the challenge would be gone. The response was that there could be levels of play — as there are now
— and that once someone won at a certain level, he or she could go on to the next one.

Some of you might consider this to be a fairly trivial issue, but the more I think about it, the more
significant it becomes. Do we want our children (and ourselves, who play these games, too) to always
be "losers," no matter how proficient we become? Should we encourage "winning'*? Is it that
important to be able to win all the time — or at least, have the chance to win? Or possibly, do we teach
more about life by encouraging our youngsters (and ourselves) to always strive for something better,

enthusiastic praise from thousands of satisfied
owners. And rightly so.
The standard Color Computer display of 32
characters by 16 lines without lower case is
simply inadequate for serious word processing.
The checkerboard letters and tiny lines give yoU
no feel for how your writing looks or reads.
Tblewriter gives the Color Computer a 51
column by 24 line screen display with tnte
lower case characters. So a Telewriter screen
looks like a printed page, with a good churik of
text on screen at one time. In fact, more on
screen text than you'd get with Apple II, Atari,
TI, Vic or TRS-80 Model 111,

On top of that, the sophisticated Telewriter
full-screen editor is so simple to use, it makes
writing fun. With single-letter mnemonic
commands, and menu-driven I/O and
formatting, Iblewriter surpasses all others for
user friendliness and pure power.
Telewriter's chain printing feature means that
the size of your text is never limited by the
amount of memory you have, and Telewriter's
advanced cassette handler gives you a powerful
word processor without the major additional
cost of a disk.

...one of the best programs for the Color
Computer I have seen. . .

TELEWRITER-64

But now we've added more power to
Telewriter. Not just bells and whistles, but
major features that give you total control over
your writing. We call this new supercharged
version Telewriter-64. For two reasons.

64K COMPATIBLE

Telewriter-64 runs fully in any Color Computer
— 16K, 32K, or 64K, with or without Extended
Basic, with disk or cassette or both. It
automatically configures itself to take optimum
advantage of all available memory. That means
that when you upgrade your memory, the
Telewriter-64 text buffer grows accordingly. In
a 64K cassette based system, for example, you
get about 40K of memory to store text. So you
donU need disk or FLEX to put all your 64K
to work immediately.

64 COLUMNS (AND 85!)

Besides the original 51 column screen,
Telewriter-64 now gives you 2 additional high-
density displays: 64 x 24 and 85 x 24!! Both
high density modes provide all the standard
Telewriter editing capabilities, and you can
switch instantly to any of the 3 formats with a
single control key command.
The 51 X 24 display is clear and crisp on the
screen. The two high density modes are more
crowded and less easily readable, but they are
perfect for showing you the exact Isiyout of
your printed page, all on the screen at onk
time. Compare this with cumbersome
^'windows" that show you only fragments at a
time and don't even allow editing.

RIGHT JUSTIFICATION &
HYPHENATION

One outstanding advantage of the full-width
screen display is that you can now set the
screen width to match the width pf your
printed page, so that "what you see is what
you get.'' This makes exact alignment of
columns possible and it makes hyphenation
simple.

Since short lines are the reason for the large
spaces often found in standard right justified
text, and since hyphenation is the most
effective way to eliminate short lines,
Telewriter-64 can now promise you some of the
best looking right justification you can get on
the Color Computer.

'FEATURES & SPECIFICATIONS:

Printing and formatting: Drives any printer
(LPVn/vni, DMP-lOO/200, Epson, Okidata,
Centronics, NEC, C. Itoh, Smith-Corona,
Terminet, etc).

Embedded control codes give full dynamic access to
intelligent printer features like: underlining,
subscript, superscript, variable font and type size, dot-
graphics, etc.

Dynamic (embedded) format controls for: top,
bottom, and left margins; line length, lines per page,
line spacing, new page, change page numbering,
conditional new page, enable /disable justification.
Menu-driven control of these parameters, as well as:
pause at page bottom, page numbering, baud rate (so
you can run your printer at top speed), and Epson
font. "Typewriter" feature settds typed lines directly
to your printer, and Direct mode sends control codes
right from the keyboard. Special Epson driver
simplifies use with MX-80.

Supports single and multi-line headers and automatic
centering. Print or save all or any section of the text
buffer. Chain print any number of files from cassette
or disk.

File and I/O Features: ASCII format files —
create and edit BASIC, Assembly, Pascal, and C
programs. Smart Terminal files (for uploading or
downloading), even text files from other word
processors. Compatible with spelling checkers (like
Spell 'n Fix).

Cassette verify command for sure saves. Cassette auto-
retry means you type a load command only once no
matter where you are in the tape.
Read in, save, partial save, and append files with disk
and /or cassette. For disk: print directory with free
space to screen or printer, kill and rename files, set
default drive. Easily customized to the number of
drives in the system.

Editing features: Fast, full-screen editor with
wordwrap, block copy, block mpve, block delete, line
delete, global search and replace (or delete), wild card
search, fast auto-repeat cursor, fast scrolling, cursor
up, down, right, left, begin line, end line, top of text,
bottom of text; page forward, page backward, align
text, tabsj choice of buff or green background,
complete error protection, line counter, word counter,
space left, current file name, default drive in effect,
set line length on screen.

Insert or delete text anywheie on the screen without
changing "modes." This fast "free-form** editor
provides maximum ease of use. Everything you do
appears immediately on the screeit in front of you.
Commands require only a single key or a single key
plus CLEAR;

truly a state of the art word processor.,
outstanding in every respect.

BUILDING MAY^ RAINBOW

Our Printer Issue . . .
Heading For New Brunswick Edition . . .
Plus, A CoCo Rock Festival . . .

In his review of Jarb Software's "talking'' Spell- A-Tron this month, Bruce
Rotherrnel hit a responsive chord with me. In explaining that many words
need to be spelled phonetically in order to sound right when the Vptrax voice
synthesizer "speaks" them, he onders if the same word will be spelled variously
according to the region of the country the program user lives in. That observa-
tion brought back memories.

As sometimes happens when you live in a very small town, my third gracje
teacher was also my mother. On occasion, she was also the spelling bee judge as
well as enunciator. One particular time, now indelibly etched in my memory, all
that stood between me and victory was the final word. She pronounced it twice
as I strained to listen: "whey-air," she ^aid, "whey-air." My heart pounded; I had
never, ever heard of this word.'

Valiantly, 1 gave it a shot, "Whey-air," 1 $aid, "W-H-A-I-R.'^ "Wrong," she
said, "WJiey-air is spelled W-H-E-R-E." What? Where?? 1 was robbed, 1
thought. "But Mom, why didn't you just say *whurr,' " 1 protested — for weeks
on end . If only she had said " whurr," 1 'd have aced out the little girl with the long
blond hair and won the spelling beje and lived happily ever after. As it was, for
years, I thought 1 was right and she was wrong and held a secret grudge against
my third grade teacher — my own mother, yet — for "doing me in."

Thanks to the advent of microprocessor technology, now every parent can
blame it on the computer if Johnny can't spell. Actually, 1 like the "analog
dimension," the shades of gray, that phonetic spelling brings to the otherwise
"either/ or" digital device we call a Color Computer, it adds a personal touch to
our CoCo that it can not only "talk" but do so with a regional accent.

But this is our printer issue isn't it? And the impact of computer printers is
definitely toward standardization of the printed word. Right? Only at first
glance. On closer examination, with printers as well, the premium is on personal-
ization. The ultimate printer, it would seem, would be one that writes illumi-
nated script with a q^ijl pen, albeit at 9600 Baud. While the technology is tiere for
scanners to **read" an entire printed page at a glance, the rush is to make one's
Qwn printer as distinctive and different as comput^rly possible. Rainbow can
help.

In this printer issue, we have everything from a "postcard whacker" to a
banner program for the Color Graphics Printer 220. Diepnis Weide delves into
"Printer Magic" while Mike Himowitz provides another "Printer Mystery."
Damon Swanson makes our good spoojer even better and Tom Szlucha pro-
vides not only a graphics screen dump, but also a label-making program for the
little CGP-1 15. bot matrix printer owners, don't despair, Charles M. Thonen
has a mailing label program for you, too.

Fred Scerbo has a printer's delight pumping out of our "Wishing Well" this
month with his "CoCo Rock Festival" and coloring book programs. Tom
Nelson digresses from his legal advice to provide counsel on selecting a printer
and Mike Fahy shows us how to create Old English, Italics and Futuristic
typefaces on the L.P. Vll or DMP-100 in his tutorial on dot graphics.

Our "CoCo Clubs" quarterly roundup of user groups appears in this issue, and
that's all the transition 1 need to issue my monthly invitation to you to join the
growing club of y?flr/>iZ?oH' readers. For $28, you get about 15 pounds of Rainbow
club materials in the form of a 340-plus page monthly magazine and we share our
vast library with you by printing a couple of dozen program listings in every issue
for you to key in and use. As clearly as I can say it, without spelling it out aloud,
we hope youll consider a "sub-skrip-shun."

locations and their contents. Figure 2
represents a printout of the disassembled
line. In Figure 2, the program line
number is printed followed by the start
address of this line and the next line.

(Dennis Weide is a communications
technician with a large telecommunica-
tions company. He teaches basic in the
evenings and writes articles and pro-
grams in his spare time,)

Beneath this, each memory location has
its contents displayed as a number or
character. Memory values from 33 to
1 27 are printed as ASCI 1 characters. All
other values are printed as decimal
numbers. This allows you to recognize
characters easily.

To find the first address of a basic
program, look at the start of basic
pointer (addresses 25 and 26). Use the
following command to compute the

start address:
PRINT PEEK(25r256+PEEK{26).

The first two bytes of a BASIC pro-
gram line point to the start address of
the next program line. The next two
bytes contain the current line number.
Figure I shows how to compute start
address and line number.

The fifth byte is the start of the varia-
ble field. If the contents of any of these

addresses is greater than 127, the BASIC
interpreter will treat it as a BASIC opcode
or mathematical function. Throughout
the entire variable field, any address
that holds a value greater than 127 is
treated as an opcode. Values of 127 or
less are treated as ASCII characters. If a
byte contains 255, the opcode is consid-
ered a two-byte opcode and the next
byte is the second half of the command.
In Figure 1, the first two bytes point to
1553 for the start of the next line. If line
10 is the only line in the program,
addresses 1553 and 1554 will both con-
tain zeros to indicate the end of the
BASIC program. Addresses 1541 to 1552
make up the variable field. The last
address, 1552, contains a zero and marks
the end of the current program line.
Disassemble more lines to familiarize
yourself with the program and how it's
stored in memory. Tables 1 , 2 and 3 are
provided to help you break down the
codes. Press [BREAK] when you are
finished to exit the program.

To see how you can use this informa-
tion to enhance your programs and list-
ings, look at the Line Printer VII con-
trol codes (Table 4). There are more
codes than listed, but for the purpose of
this article, these are enough. The fol-
lowing ideas will work with any stand-
ard printer if you substitute the proper
control codes for the ones listed.

Back in Figure 1, address 1547 stores
a value of 32. Since this is a character
code (ASCI I), it will print a blank space
when sent to the printer. If you POKEa
value of 3 1 into that address, the printer
will be set to large font when this line is
listed to the printer. If you POKE
address 1550, which also stores a 32, to
ASCII code 30, the printer will be reset
to small font at the end of the line. When
you run or list the program to the print-
er, the word "HI" will be printed in large
block letters. When printing or listing to
the screen, the control codes are trans-
parent to the computer. Figure 2 shows
the line as listed before embedding
codes, then shows the disassembled
line. You can use the /*C>/l£ commands
in the figure and then disassemble the
line again. When you LLIST the pro-
gram line, the "HI" is in large letters and
the rest of the line is in small letters.
Now run line 10. Again, the word "HI"
is printed in large letters.

It is too time consuming to PEEK
and POKE addresses to embed your
codes in a program. But Printer Magic
does the job quickly and easily. It uses
special characters (see Table 5) which
you type in your program. Look at List-
ing 2. In line 5, the program looks at the

start of BASIC pointer to compute the
start address of your BASIC program.
Line 6 looks at the second two bytes of
the program line to calculate the line
number. Line 7 calculates the start
address of the next line and saves it as a
variable. Line 8 checks to see if the cur-

'7/ is too time consuming to
PEEK and POKE addresses
to embed your codes in a
program. But Printer Magic
does the job quickly and
easily. "

rent line number matches the one you
requested. If not, the program goes
back to line 6 with a new address and
starts looking again. If it is, lines 9
through 14 read the variable field and
change any of the special symbols to the

proper control codes. Lines 15 and 16
allow another line selection and line 17
checks to see if your last line number is
lower than the previous one. If lower,
the program returns to the start of
BASIC pointer; otherwise it will continue
down the line.

I have included examples 1 , 2 and 3 to
show what Printer Magic can do. Each
example lists the line with the special
symbols before running Printer Magic
and with the control codes after running
it.

The best way to utilize embedded
codes is in string variables, DATA
statements and REMark statements.

When writing a program, save a final
copy before running Printer Magic to
insure that you do not accidently poke a
control code where it can cause prob-
lems. You can load Printer Magic before
writing your program or load it back-
to-back with your program when ready
to embed codes.

Since both programs are written in
BASIC, you can modify them easily. And
I'm sure you can find more interesting
ways to utilize both programs. In the
meantime, you can enhance your favor-
ite program listings and printouts for
eye appeal and easier reading.

Make The Good
Spooler Better

By Damon Swanson

Steve Good's Spooler ((he Rainbow, June '83) is an
excellent example of using the Color Computer in a
multitasking mode. This means that your CoCo can
do two jobs at one time. (We'll be hearing a lot more about
that as people start using the OS-9 operating system.) There
were, however, two things that limited the program for my
use. First, it stole graphic memory, and second , it would not
work with I^adio Shack's Screen Print program.

With a working 64K system, it is a simple matter to move
the spool buffer from graphic memory to the 32K of hidden
RAM and in the process create a buffer large enough for
almost any need. The first program provides ^ patch to Mr.
Good's spooler to do just that.

The modification of Radio Shack's SC/^/^/^T routine to
work with the Good Spooler and provide full compatibility
with the disk operating system is a little more complex. The
second part of this article shows how to append SCRPRTio
the Spooler and patch it for full disk operations.

32K Spooler

If you have a good 64K CoCo, you can easily modify the
Good Spooler to use the 32K of RAM not accessed by BASIC
as the print buffer. Load Good's source listing in your
assembler then make the following changes referenced to its
current line numbers. ♦

First, change the origin from screen memory to the top of
BASIC RAM:

00020 ORG $7F65

This means, of course, that you must reserve meniory for
the program by a CLEAR &H7F65 before RUNning the
program. Change the end of buffer previously in low RAM

(Damon Swanson manages 130 engineers and technicians in
the engineering test department of a major high-tech com-
pany. His computer hobby keeps him from meddling in the
work of his staff which includes programming M6809 and
M6800 ihicroprocesSors to solve special measurement and
test problems.)

tp the top of the 32K RAM page:
00200 LDX #$FEFF

Also change the beginning of buffer to the start of the
upper RAM page:

00220 LDX #$8000
00790 LDX #$8000

1 have made buffer references absolute so that the driver
can be relocated anywhere in low memory.

Now we are ready to add the code that switches from the
ROM (Type 0) to the RAM (Type I) memory map before
each load or store to the buffer and to switch back after-
ward. Do this by adding lines:

00405 CLR $FFDF
00415 CLR SFFDE
00745 CLR $FFDF
00755 CLR $FFDE

Finally, delete line 00880 (we don't need this reference
anymore) and Sooper Spooler is ready to assemble.

You now have a print buffer considerably larger than the
memory available for BASIC programs, and a direct way to
use that extra memory. Since our new buffer is located
nicely out of graphic space, one thing we might use it for is to
speed up the Screen Print routine.

Compatible Screen Print

Before we can use Spooler with Radio Shack's SCRPRT
program there are two problems to solve. SCRPRTtnusi be
relocated and then patched so that it uses BASIC 1 . 1's regular
8-bit print driver. Otherwise, its print routine will not com-
municate with Spooler. SCRPRT\s one of the worst exam-
ples of 6809 code I've ever seen. It is completely position
dependent and almost defies relocation.

Fortunately, Tom Goodrick came to the rescue with a
program to do this relocation.

Tom's trick uses the fact that the Hex values 3D, 3E and
3F, representing the most significant byte of every absolute
address in the 5C/?/'/?r program, appear nowhere in the

May 1984 the RAINBOW 23

program except as absolute addresses. As a result, we can
simply run through the listing with a short basic program
that adds $40 olTset each time it encounters one of the
olTending Hex values.

The BASK* program ol Listing I uses Mr. Goodrick'^
scheme in a dillerenl and simpler program. Enter the BASK

f urogram, then put the SC RPRTiixpi: in the recorder. Press
PLAY] and run the program. When the [OK] prompt
appears, CSAVEM to tape or SAVEM on (Jisk using
&H7D80,&H7FFF,&H7D80 as the START, END and
EXECUTE parameters. Our Spooler patch will correct
some other deficiencies.

Mod jfy the revised Spooler source to locate it in front of
the screen print roytine overwriting SCRPRTs initializa-
tion which is no longer used.

Add to Spoolers initialization section the lines from
SCRPRT's code that sets up to look for and respond to the

require a distinction for the two passes required to print a
full screen of graphics.

Delete the END statement in line 00890, then add the
source of Listing 2 to your assembly. Note that this code
changes the command key from the up arrow to the down
arrow as suggested by Qoodrick to free the up arrow for
normal line editing.

The machine returns to your use a few seconds after the [i]
command for a screen dump that" normally takes several
rniputes to print.

Before turning off the computer, CSA VEM or SA VEM

RAINBOWfest
Report:

Even without corn dogs, it was a three-
ring circus weekend for thousands at
Long Beach

Breakfatt keynoter Bob AlbrecM (above) celebrated his birthday at RAINBOWfest. The crush
ot people In the main ballroom exhibit hall (below) gave the three-day event a carnival flavor.

Sharry Zuahike, praaldant of the South Bay Color
Computar Club, sarvad on the woman's program
panel.

The crowd at Computerware (above) wanted pro-
grams while books were the thing at the Dymax
booth (below).

For a fleeting weekend, Feb. 17-19,
Long Beach, Calif., became CoCo
Beach as more than 8,000 Color Com-
puter users flocked to the Hyatt Regency
and packed the exhibit hall and seminar
rooms to learn about the latest devel-
opments for our favorite personal com-
puter.

Our second RAlNBOWfest of the
season drew people from as far away as
Canada, Panama and even England.
Those of us from the colder regions
enjoyed the palm trees and sunshine
even if the weather was a bit brisk for
the beach. Content to stay inside, we
followed the crowd headed for the main
ballroom exhibit hall.

It was like a three-ring circus at times
with seminars competing with Radio
Shack*s CoCo Classroom, and both
running during exhibition hall hours.
The litany of CoCo Community per-
sonalities attending is too long to recite
here, but it ranged from CoCo estab-
lishment types like Bob Albrecht and
Don Inman to real comers like Roger
Schrag and controversial mavericks like
Dr, Marty Goodman.

RAlNBOWfest CoCo Beach provided
a chance for in-depth, one-on-one ex-
planations when time permitted as well
as aisle-blocker, crowd-stopper demos
that reminded one of the state fair mid-
way barkers hawking vegetable slicer-
dicers. Most of those attending were so
engrossed in examining the newest in
software and hardware that when the
Rainbows Jim Reed mistakenly an-
nounced that the Radio Shack booth
was closing out its 64K ECB machines
for just S 1 49, it caused no stir at all. No,
there were no corn dogs, but an elabo-
rate Hyatt sandwich station just outside
the ballroom drew a lot of takers.

By the end of each day, most people
had plenty to fill their shopping bags:
souvenir tee-shirts to arcade games,
database programs to hard disk drives.

Will we be back next year? You bet!
And, in the meantime, well visit New
Brunswick (March 30-April 1 ) and Chi-
cago (June 22-24). The CoCo Commun-
ity and RAlNBOWfest are too big to
stay in one place.

In Pursuit Of
Captain 'Hook'

A report on the
piracy seminar at
RAINBOWfest-Long Beach

By Bill Nolan

Rainbow^ Contributing Editor

One of the best attended and most controversial
seminars at the recent RAINBOWfest in Long
Bedch, Calif, (which was an absolutely outstanding
event), was the panel discussion held on the subject of soft-
Ware piracy.

The merribers of the panel were Martiri Goodman, M.D.,
a gehefal pJ-actitioner arid anesthesiologist, owner of Che-
shire Cat Software, ^nd a CoCo enthusiast; Paiil Searby,
owner of ComputerWare; and Bob Rosen, owner of Spec-
trum ^Projects, and SYSOP of the Rainbow Connection
Bulletin Board. Each of these gentlemen made a short open-
ing comment, and then questions from the audience were
fielded. Jim Reed, managing editor of the Rainbow, moder-
ated the discussion.

Goodman, who has becoine Well known to CoCb users
because of his skill at '^bheaking" protected software, spoke
out strongly in his opening remarks foi* more comrhurtica-
tion between software vendors and Customers. He also
pointed toward what he believed to be a strong need for
more accountability from vendors as to advertising claims,
warranty, and providing of backup media in a reasonable
way.

Searby is an outspoken believer who has taken the lead in
anti-piracy campaigns. His opening comments reflected his
convictibn that piracy (he always says "theft'\ not "piracy")
is the biggest problem facing software vendors and software
users alik6. He feels that software theft is causing vendors of
good software to leave the field, and he cautioned that the
currently rampant sbftware theft problem has, and will,
result ill higher prices and less software being available.

Searby provided a quick overview of the rather extensive
costs involved in bringing a new program to the marketplace

(Bill Nolan and his wife Sara operate Prickly-Pear
Software, Bill also teaches computer science at a local
collegia and is DM at U regular weekly fantasy game,)

— costs that often reach $ 10,000 according to Searby — and
he reminded people that these costs must be recovered by the
sales of the program. If fewer copies are sold because of
piracy, then each copy that is sold has to bring a higher price
in order for the vendbr to recover his costs, and (hopefully)
make a profit. He mentioned also that publishers sell most
df their programs to dealers and distributors at about half of
the Suggested retail price, and that the price has to be set
accoi*dingly. Searby also said that some vendors who had
previously been a problem from the standpoint of warranty
and backup have made great improvements in these areas,
due to efforts within the industry to police itself.

During the question period, it was asked why some com-
panies put so much protection onto their tapes and disks
that loading becomes a problem. Datasoft, in particular,
took a lot of "heat" ori this subject, with one dealer in the
audience indicating a return rate of 90 percent on Zaxxon
tapes. A representative of Datasoft responded by saying that
Datasoft had not manufactured the tapes. He also provided
soine numbers to indicate the size of the piracy problem that
led them to institute the protection to begin with. Appar-
ently, thei'e were about 5,000 copies of Zaxxon sold, (Searby
indicated that, with most programs, 3,000 copies sold over a
one-year period is considered outstanding), yet there are an
estimated 300^000 copies in existence, fora ratio of 60 stolen
cOfjies to every legitimate copy of Zaxxon. A member of the
audience remarked that when Radio Shack began selling
ZaxxOn, they sold it without the protection on the tape.

It was asked what was "public domain," and whether or
not programs typed in frotn magazines were okay to pass
arourtd. Reed, from the Rainbow fielded this one, and he
said that every issue of the Rainbow, and almost every other
magazine as well. Was copyrighted in its entirety, and that in
addition, the authors of the various programs retained their
own copyright, so these were not "public domain," and
could not be legally distributed or placed on bulletin boards.

Marrying Machine
Language To BASIC

By Richard A- White
Rainbow Contributing Editor

James H, DeStafenoof Swedesboro,
New Jersey wrote the Rainbow
askinga numberof questions which
might occur to you if you have becotne
conversant with BASIC and start looking
at machine language for the first time.
He notes that ROM and memory maps
are being printed without instruction on
how to use them. Other foggy BASIC
commands include CLEAR xxx.yvy^
USR. DEFUSR and offset loading,
PEEK. POKEsLXid VAR FT Rhawc been
recently covered in the Rainbow, but
belong with the above commands in
that they deal directly with CoCo*s
memory.

The 6809 microprocessor can directly
address 65535 bytes of fnemory. A mem-
ory map describes in a table, diagram or
listing where and what is in the rhemory.
The memory map depends on the oper-
ating system in the machine at the time-
Color BASIC is an operating system that
defines a basic memory map for the
CoCo. Extended Color BASIC changes
this map in detail as it allocates space

(Richard White has a long background
with microcomputers and specialize^ in
BASIC programming. Along with Don
Dallberg, he is the author of the TIMS
database management program.)

for the new functions it provides, but
does not change its basic structure. Disk
BASIC needs room to operate too, so it
grabs off some more of the memory ahd
the memory map changes again, if you
do a PRINT MEM in a Color BASIC
machine and then in a Disk basic
machine, you get a much smaller num-
ber in the Disk machine. The memory is
still there, but Extended BASIC and Disk
Basic are using it.

Let's examine the above memory map
in some detail. In the first 1,023 bytes,
BASIC keeps its notes that it needs to
run. These are things like the address of
the start of BASIC (25 and 26), the end of
BASIC (27 and 28), variable table ad-
dresses, the end of memory and a myriad
of other details. Ever wonder how BASIC
keeps track of where the cursor is on the
text screen? That's in 136 and 137.
When you type on the keyboard, things
generally don't happen other than char-
acters appearing on the screen until you
press [ENTER]. That's because the
characters are saved in a memory area

May 1984 the RAINBOW 31

called a buffer until a carriage return
character is sent by the [ENTEjR] key.
This BASIC line input buffer starts at
decimal 832 and is 255 bytefe long.

Another important buffer is the cas-
sette file data buffer Which starts at
decimal 47 1 and is 256 bytes long. When
you output data to a cassette file, data is
temporarily stored here until the buffer
is full and then dumped to tape. Upon
loading a cassette file,\data is stored
here for basic to read and pfocess.
Other earlier comjjuters didn't have
slich a buffer and each piece of data was
individilally sent lo tape along with a
time consuming header. Ldading or sav-
ing a file can be an all hight chore with
these machines.

It is well beyond the scope of this
column to deal individually with each
item in BASIC'^ scratchpad; most you
will hever need to Use directly. Some
you set using basic commands, but
BASIC does the work for you. In any
case, this 1 K chunk of nlemory is one of
the mcisi used in your machine. While it
is not included in tKe number you get
when you PRINT MEM, it is working
hard for you nonetheless.

Next comes the vital screen memory;
It extends from decimal 1024 to 1535
and has one byte for each possible char-
acter location on your text screen. When
you print to the screen, BASIC stores the
characters here. Your video display gen-
erator chip (6847) reads this data and
converts it into the picture it sends to
your TV or monitor. Your video display
generator chip deals with graphics in
much the same way when you use the
graphics modes. It reads the assigned
memory area and generates a picture.
Motorola devised this method years ago
for use with the 6800 miCfoprocessor. In
a recent article in BYTE magiazine,
Apple people were making a big thing
about using the technique in the new
Macintosh. The only thing different is
that the Mac uses a 68000 instead of a
6809 and has a 22K graphics memory
space i-ather than the 6K used for high
resolution graphics in the CoCo. The
8088 microprocessor in the IBM PC
works differently from the 6809 or 68000
and a whole board of chips are neces-
sary to do what one or two chips do in
CoCo or Mac. This is one of those
details that explain why a $260 machine
can do so much of what a $3,000
machine will do.

Next come the graphics pages. Color
BASIC does not have graphics cap-
ability from Basic, so the basic pro-
gram default start address is 1536. On a

cold start. Extended basic reserves foiir
pages for memory, so the start of a
basic program is at 7680, but you can
use PCLEARio change this.

For example, if you enter PC LEA Rl ,
only the first graphics page is reserved,
and the basic program will load start-
ing at 3072. This allows 12,71 1 bytes for
basic program and variables in a 16K
machine. On the other hand, a
PCLEAR8 moves the start of BASIC all
the way up to 13824 leaving a trifling
2,559 bytes for basic and variables.

In a 32IC or 64K machine, the RAM
between i 6384 and 32767 is all available
fOr program and variables. In a Color
basic machine, this is a large 31,231
bytes. With Extended Coloi* basic,

PCLEARl allows 29,6<35 bytes, there
are 25,087 bytes available with
PCLEAR4 and 18,933 available with
PCLEAR8,

If you do a PRINT MEM under one
of the combinations described above
after a Cold start, the number returned
will be 200 bytes smallet" than 1 show. If
you have an Extended BASIC machine
and enter PRINT MEM Immediately
after turning it on and getting the Ex-
tended BASIC message, you will read
24,887 rather than 25,087. The differ-
ence is the 200 bytes that BASIC auto-
matically reserved for strings. You
change this by lising CLEAR 100 to
reduce it to lOO.bytes. Maybe your pro-
gram is going to store a lot of string data
so you CLEAR 5000 or even CLEAR
wood. This reserved space is no longer
available for a BASIC program and most
variables. Only string data can be placed
there. It's not lost since you have to put
string data soniewhere. The trick is to
size your string storage to meet your
program's needs without unduly limit-
ing your program's size.

CLEAR can carry two arguments,
for example CLEAR 200.27000. This
says that BASIC may not use any memory
above 27000 in a 32K machine, and that
the 200 bytes just below 27000 in mem-
ory are reserved for string storage.
Machine language programs may be
loaded above 27000 and EXECuted
without fear of being "walked-on" by
BASIC. Prickly Pear's Colorkit is a
machine language set of editing tools
that 1 always have running when 1 do
any serious BASIC prograrnming work.
It starts at 27000 in my 32K machine so 1
have to type CLEAR 200,27000 from
the keyboard before loading it. Other-
wise, CoCo goes west and 1 have to turn
it off and back on to recover. You want

to reserve only the amount of memory
for machine language that you need. I
used CLEAR 200,27000 since that is
what is required to use Colorkit. If you
had a 1,000-byte machine language
program thert CLEAR 200 J 1767,

We have slid into the dual operation
of BASIC and machine language pro-
grams at the same time. In the example
above, Colorkit can be running while
you run the BASIC program you are
working on. Actually there are three
programs working simultaneously since
your BASIC interpreter is a machine lan-
guage program. Really, each is taking
Its own turn and then handing control
back to another. Overall control of this
rests with addresses or "hooks" stored
in the system portion of memory belo\y
1023. We are getting deep fast here, and
disengagement is preferable to total
confusion. Perhaps this leaves you with
some flavor of what can be going on
that we do not see clearly.

A simpler exercise is to store a ma-
chine language routine in memory
and call it from a basic program when

''The trick is to size your string storage to meet
your program 's needs without unduly limiting your
program size. "

32 the RAINBOW May 1964

you want to use it. Starting with Color
BASIC, you need to POKEihc execution
address of the machine language into
memory locations 275 and 276. Then
when you need to call the routine from
inside a BASIC program, you use the
statement A-USR(0). You can write
your machine language routine to use
the ROM call INTCNV to get the
argument with USR, 0 in this case and
put it in the D register of the micropro-
cessor. Generally you won't want to
bother with this. You can also transfer
data to the machine language routine by
POKEing values to some reserved area
of memory. The routine then can get the
values, work on them and then store
new values for BASIC to get by peeking.
Now you are really down at the machine
level, dealing with memory on a byte-
by-byte basis.

Some have been trying to get a handle
on assembly or machine language pro-
gramming by trying to understand how
to interface it with BASIC. A better way
is to learn assembly language, at least
the simpler aspects, and then work back
to the interface with BASIC. When you
understand what simple machine lan-
guage programs are and how they work,
you will understand more clearly what
the BASIC interface tools are doing.
TRS-80 Color Computer Assembly
Language Programming by William
Harden, Jr., Radio Shack cat. no. 62-
2077, is a good starter reference.

Extended Color basic broadens the
machine language interface, allowing a
BASIC program to call any of 10 machine
language routines (numbered 0 to 9).
First the execution address of each rou-
tine to be used must be defined to BASIC,
not POKEd into memory as with Color
BASIC. The format is — DEFUSRn =
address. Say 1 had three routines whose
execution addresses were 31000, 31500
and 32000, each address being also the
first byte of each routine. Before load-
ing these into the computer, either the
program or the operator would need to
do CLEAR xxxJlOOO to protect the
machine language area. Next the BASIC
program would need to define the exe-
cution addresses as follows — 2000
DEFUSR0=3I000 : DEFUSRI=3I500
: DEFVSR2 = 32000, A machine lan-
guage routine is then called with a
USRn statement — A=USRn(B). To
call routine one, use 100 A=USRI(0),
When the routine completes its work,
control is returned to either the next
statement in the line or to the next line
in the BASIC program.

While it is desirable to put machine
language routines either below BASIC in

the graphics pages if you are not using
graphics or in a protected space at the
top of memory, it is not necessary that
they be assembled in jihe final memory
location. In other words, routines that
are written in relocatable code can be
moved around in memory and still
work. If you upgrade to a 32K Or 64IC
machine, you would like to take advan-
tage of that memory and you cannot if
you continue to load machine language
routine in protected memory below
16383. Yet your routines on cassette or
disk are made to load into the lower
memory area. Offset loading to the
rescue. In a simple move from I6K top-
of-mcmory to 32K top-of-memory, do
CLOADM "PROGNAME'\ 16384 or
LOADM "PROGNAME'\ 16384. The
program will load 16384 bytes higher in
memory. To make it easy later, C-
SA VEM or SA VEM the program from
higher memory using the new start, end
and execute addresses* It will now be on
your tape or disk with these new ad-
dresses and can be loaded directly with-
out offset.

One of the neater tricks around is to
hang your machine language rou-
tines onto your BASIC programs so they
load and save with the BASIC program.

Metric Industries

To understand this, we need to know
what the end of a BASIC program looks
like and to what address the end of
BASIC pointer at locations 27 and 28
points. Each line of basic ih memory
ends with a zero. There are three zeros
in a row at the end of a BASIC program.
The end of BASIC pointer carries the
address of the memory location follow-
ing the third zero. Load a machine lan-
guage routine starting at the second
zero marking the end of BASIC, then add
three zeros after the machine language
and change end of basic to hold the
address following the new three zeros.
At minimum, you will need a machine
language monitor program that can
read and change individual memory
locations. Colorkit includes both the
monitor and a utility to attach the
machine language routine automatic-
ally to a BASIC program. Now when you
save and load the BASIC program, the
machine language loads and saves with
it. If you edit the BASIC program, its
length changes and the machine lan-
guage is moved up or down in memory
with the program.

The next problem is to call the ma-
chine language whose execution address
changes from time to time as you edit

BASIC, Since the end of BASIC pointer
changes the same amount and direction
as the location of the machine language,
we can use it for a reference. In Extend-
ed BASIC, this will do the job: 100
DEFUSRO = 256*PEEK(27) + PEEK
(28)- X where X is the number of bytes
from end of BASIC to the execution
address of your routine.

N ow why would one want to play silly
games like we have been talking aboiit?
Program speed is one good reason. A
sorting routine in BASIC is slow, even if
you use the fastest type of sort. In com-
parison, even the slowest sorting meth-
od in machine code is 10 to 100 times
faster. Writing a whole program in
machine code woiild be a real drag.
Writing Just a sort and hooking it to a
BASIC program that does as well as the
rest of the things you want done is much
less painful. Games are another area
that benefit from the use of key machine
language routines doing only things
that BASIC is slow at.

36 the RAINBOW M&y 1984

there is the Extended BASIC ROM, the
Color BASIC ROM, cartridge memory
and input/ output. The Disk BASIC
ROM occupies the lower 6K of the car-
tridge memory space in a disk system.
At minimum. Color BASIC and input
/output, our beloved SAM chip (6883),
must be present to provide a minimum
operating system. Using either cassette
or disk, machine language routines can
be loaded that cause drastic memory
map changes to occur. Some of these
have been published in recent back
issues of the Rainbow. A first step is to
copy the ROMs to low memory, switch
CoCo to 64IC RAM and copy the ROM
code back into upper memory in the
same locations that it occupied in ROM,
Next it was discovered that Extended
Color BASIC is entirely relocatable, and
that if it is moved above Color basic or
Disk BASIC, that BASIC could use RAM
up to 40959, This is the so called 401C
move and a number of commercial and
published programs are available. An-
other interesting approach is the one
developed by Jorge Mir to modify a
BASIC program and load it above Disk
BASIC. This is in the October 1983
Rainbow.

Another tact is to switch the upper
32K RAM in and out under con-
trol of a machine language program and
use the upper RAM for data storage.
BASIC is operational whenever the ma-
chine is in the ROM mode. Under these
conditions, 96K of memory space is in
use. In any case, the memory map is one
thing at one time and something else at
another. These are enhancements to the
BASIC operating environment and do
not cause major changes to BASIC.
Properly written, a BASIC program that
runs in the normal ROM-RAM map
should run in an all RAM or switched
mode as well. Changes required should
be restricted to those necessary for the
program to take advantage of its new
environment.

At this point there is much that 1 have
not covered and some that 1 have
touched only lightly. The disk system
memory map is one that is not dis-
cussed. One reason is that it varies
depending on how many disk buffers
are in use. Another is that there are
many more non-disk readers than those
with disks. The whole area of switching
from ROM to RAM in the upper 32K
space could well be the subject of a
separate article apart from this column.
For now, let's get the basics in place,
even when they seem rather complex
themselves.

A Change Of Address

By Dennis Derringer

Recently, quite a few programs have been popping up
that show an effective means of relocating machine
language programs in memory. Of course, to have a
machine language program load at a higher address only
requires an offset value placed after the filename when it's
LOADMed, Unfortunately, Microsoft didn't include a syn-
tax for negative offsets to load programs lower in memory.
This spurred the challenge to offer a means of relocating
programs after they're loaded in memory. Most of these
programs dealt with a technique using PEEK and POKE,
either in BASIC or a machine language version, to move an
area of memory from one location to another. Effective, yes,
but it still required you to calculate the new LOAD, EXEC
and END addresses so that it can be SA VEMed.

Being one who likes things nice and simple, I proceeded
to find a quick method to relocate machine language pro-
grams and at the same time, have the addresses changed.
Studying the method by which a machine language program
is stored on disk revealed that the three magic numbers are
right there on the disk with the program. All that was needed
was a routine that could read these numbers and then have
new ones put in their place. This is where the flexibility of
RS'DOS really proved outstanding.

Regardless of how a file is stored, you can OPEN it for
direct (random) access with a record length of one and then,
by checking the length of the file (LOF), obtain the exact
number of bytes that it contains. For machine language
programs, the second and third byte in the file represent the
M S B and LS B values for the LEN GT H of the program . The
fourth and fifth bytes represent the MSB and LSB values for
the LOAD address. The last two bytes in the file represent
the MSB and LSB values for the £A'£'C address. The actual
numbers for the MSB and LSB values are the ASCII value
of the character. The number which they represent is calcu-
lated by the formula MSB*256+LSB.

The utility program will obtain these values and let you
indicate a new LO/iZ) address. The LENGTH and EXEC
values are automatically recalculated and then the new
values are stored back on the disk. This is how the program
breaks down:

(Dennis Derringer, president of Derringer Software, Inc., is
a self-taught programmer and has been marketing software
for the color computer since 1982,)

Line

90- 1 80 Receive input for filename and get values from

disk (include extension).
200-250 Display values and receive input for new LOA D
address.

270-390 Calculate new values, display values and store
result back on disk.

This routine works with any program that has been
SAVEMed using the standard syntax. Exercise caution
when using with commercially purchased software, they
don't always use standard techniques.

The best doesn't always cost more and MASTER CONTROL 11 is a good
example. What would you be willing to pay for a program that would cut
your typing time by more than 50% and eliminate hours of debugging
because you misspelled a command word? For example the command
STRINGS (requires nine strokes) with MASTER CONTROL II you only
require two strokes, just hit the down arrow key twice and it's done, and
no mistakes. That is just one of the 50 pre-programmed commands
available to you. If that isn't enough you also have the ability to customize
your own key to enter a statement or command correctly, automatccally
every time. But that's not all, how about automatic line numbering. Just
enter the starting number and the increment you want and MASTER

This article describes, in detail, modifications that 1
have added to a fine program by Mr. David Steyer
{seethe Rainbow, Janu'dvy 1983, Page i90)* The mod-
ifications are designed to take advantage of some of the
capabilities of Radio Shack's CGP-220 and produce "solid"
color or inverse graphic characters using the CGP's **bit-
image'' mode. If you liked this program running in the
non-graphics mode, as 1 did, then Pm sure you will enjoy the
colorful result of this modification running your CGP-220.
The printer control code additions/ modifications, which
represent the primary alterations, are documented within
the BASIC program lines and, although they are for the
CGP-220, probably are easily adaptable to codes for other
printers capable of "bit-image" graphics.

Color Graphic Banner utilizes the ability of the CGP-220
printer to switch back and forth between the text and bit-
image modes. The text mode is the mode the printer is in
when it is switched on and is primarily utilized to print
alpha-numeric characters. By using special printer control
codes, the CGP can alter the color of text characters and can
be set to the bit-image mode, in which it "assumes" that it
will receive instructions for printing a dot or column of dots
(up to seven dots high) in one or more of up to 640 such
columns across in one row. In addition, upon entering the
bit-image mode the printer "assumes" that any such rows of
dot-columns will be adjacent to one another vertically and,
thus, a line-feed in this mode leaves no space between rows.
When exiting the bit-irnagc mode, the color, and other
conditions, which existed prior to entry, are restored.

With this information in mind, 1 shall discuss all the
changes In the listing that follows.

(Doug Lindsay is a personnel analyst for the City of
Everett (Wash.) He possesses a bachelor's degree in psy-
chology and a master's in public administration, Doug
finds satisfaction in both serious and not-so-serious
Color Computer programming.)

The first modification occurs in line 60 which clears twice
as much string space, since 1 chose to add strings in which to
build graphics information and store control codes while
retaining the original string variables. The poke in line 60 is
optional and allows data to be sent at the highest rate at
which the CGP-220 can operate. You must, however, make
sure that the Baud rate select switch (located on the rear
panel of the printer) is placed next to the proper setting.
That is, if you elect not to use the poke, set the switch next to
the number 600. If you leave the poke in, set the switch next
to the number 2400.

Line 100 contains a change in the input to variable "LG"
and, thus, allows for selection of the CGP's 91 text-column
line width.

Line 120 prompts for a wider (seven instead of five) sug-
gested character width because the bit-image line-feed com-
pacts rows of graphics which makes the Color Graphic
Banner characters narrower than the non-graphic ones.

Line 145 adds a brand new input statement which
prompts the user to select a character color and stores the
numerical code for the selection in the variable "CL." The
color codes are listed in the CGP-220 manual, but please
note that I have chosen to modify two of the designations.
Pm sorry, but what the book calls violet looks like blue to me
and vice versa.

Line 275 directs storage of a series of control codes in
variable "LF$." CHR$( 18) places the CGP in the bit-image
mode, CHR$(I3) does a line-feed (remember, it's compact
because of the bit-image mode) and CHR$(30) causes an
exit from the bit-image mode, as well as restoration of all
prior text mode conditions. This allows using simpler basic
commands to send blank spaces to the printer rather than
utilizing a more complex print-head positioning routine.

Line 485 simply sends the CGP's color change control
code CHR$(27) "T" followed by the numerical color code
stored in variable "CL."

Line 510 retains the original program's string variable
"B$" to control centering of graphic characters on the
banner. Lines of characters are built in a new variable
"GF$." This variable builds a line of "solid" color and/ or

May 1984 the RAINBOW 41

spaces of a particular height (as specified in variable "H H'').
The actual color graphic portion of the line consists of the
following: CHR$(I8), for bit-image initiation; CHR$(28),
signals repetitions of a graphics dot-column; CH R$(H H*7),
sends the number of repetitions; CHR$(255), defines the
dot-column pattern to be repeated (in this case it is a 7-dot
column). This sequence of codes causes printing of HH*7
dot-columns in a row. Each column, in turn, is 7 dots high.
CHR$(30), as you may recall, causes exit to the text mode.
The "solid" color graphic effect, of course, results from the
density of the lines of color dot columns "packed" together
by means of the bit-image line-feed. The banners produced
are colorful and easily read even from quite a distance.

Line 540 clears the graphic line-building strings before
looping to set up the next line of graphic information to be
sent.

Line 555 sends a line-feed code merely to empty the prin-
ter buffer and, thus, avoid incidental printing of garbage.
This line also clears the screen and prompts for an easy
restart. I have found that mixing various colors of letters,
words and/ or symbols by creating them one at a time can
yeild eye-catching banners, nametags, labels etc.

Line 560 restarts or prints sorne colorful credits, prior to
setting the print color to black and ending the program.

As Mr. Steyer stated in the article that was published with
the original version, the program supports all ASCII char-
acters (though the lowercase letters are sans descenders) and
I Ve found that attractive name lags can be generated in the
inverse mode. For example, try a character height setting of
one and width of two. These settings yield elongated graphic
characters such as those in the sample output.

I hope you have fun creating your messages in bright color

graphics. Kids of all ages seem to take great pleasure in
seeing their name in a Color Graphic Banner and, if youVe
not too shy, you can drop hints that CGP ink packs (as well
as paper) make really nice gifts!

The Library Concept

State of Ihe Art, Quality, Integrity,
Compdlibility and Affordability. Five
things good software must possess.
Five things fhal epitomize the VIP
Library"*. Each program is the
diamond of its class, true excellence.
These programs are first in features,
first in power, first in memory, and
all are affordabiy priced. And for
your convenience all disk programs
can be bdcked up.

Stale Of The Att

All Librafy programs are written in
machine code specifically for the
Color Computer, to work without
the inierference of a separate
operating syslem such as FLEX. From
this come^^ speed and more work-
space for you. Unlike other programs
for the Color Computer which are
said to be 64K compatible, VIP
Library"* programs are not limited to
between 24 and 30K of workspace in
64K. library programs have Memory
Sense wilh BANK SWITCHING to
fully use all 64K, thus giving up to
51 K with a disk version and up to
53K with a tape version.

Easv To Use

Each library program was carefully
d<»signed to be extremely easy to
use. Built-in on-screen help tables
are at your fingertips, as are menus
of all kinds. Every effort is made to
use logical, intuitive and easy-to-
remember commands. The manuals
have been thoughtfully prepared to
cover every aspect of the program,
and they have complete tutorials to
get you goin^ right away. We set the

nm 1 COLOR COMPUTER M . i

The most powerful and easy-to-use word processor is available in the
showpiece and workhorse of the Library: The VIP Writer^*. Because of its
undisputed superiority over all Color Computer word processors, it was
selected by Dragon Dat3 Ltd. of England and TANO In the U.S., to be the
Official Word Processor for their line of Dragon microcomputers.

The result of two years of research, the VIP Writer"" offers every
feature you could desire from a word processor. It is the most
powerful, fastest, most dependable and most versatile. With the hi-res
display, workspace and compatibility features built into the Library the
Writer is also the most usable.

. Nearly every feature and opOon possible to implement on the
Color Computer. The design of the program is excellent; the
programming is flawless . . . Features for the professional, yet it is easy
enough for newcomers to master . . . Certainly one of the best word
processors available for any computer . . " October 1983 "Rainbow"

"Wordprocess/ng with VIP Writer is like driying a high-performance
\/ehicle . . This Ferarri of a package has more features than Telewriter,
Easywriter (for the IBM PC), or Applewriter/' October 1983 "Hot CoCo"

The Writer will work with you and your printer to do things you
always wanted to do. Every feature of your printer can be put to use,
every character set, every graphics capability at any baud rate, EVEN
PROPORTIONAL SPACING. All this with simplicity and elegance. You
can even automatically print multiple copies.

Although all versions feature tape save and load, the disk version
provides the Mini Disk Operating System common to the whole
Library, plus disk file linking for conttnous printing.

Professional features of particular note:

■ Memory-Sense with BANK SWITCHING to fully utilize 64K, giving
not Just 24 or 30K, but up to 61 K of workspace with the rompak version
and 50K with the disk version.

• TRUE FORMAT WINDOW allowing you to preview the printed page
ON THESCREEN BEFORE PRINTING,showing centered lines, headers,
FOOTNOTES, page breaks, page numbers, & margins in line lengths of
up to 240 characters. It makes HYPHENATION a snap.

» A TRUE EDITING WINDOW in all 9 display modes for those extra
wide reports and graphs (up to 240 columns!).

» FREEDOM to imbed any number of PRINTER CONTROL CODES
anywhere, EVEN WITHIN JUSTIFIED TEXT.

■ Full 4-way cursor control, sophisticated edit commands, the ability
to edit any BASIC program or ASCII textfile. SEVEN DELETE

How To Read Rainbow

Please note that all the BASIC
program listings you will find in the
Rainbow are formatted for a 32-
character screen — so they will show up
just as they do on your CoCo screen.
One easy way to check on the accuracy
of your typing is to compare what
character "goes under" what. If the
characters match — and your line
endings come out the same — you have
a pretty good way of knowing that your
typing is accurate.

We also have "key boxes" to show you
the minimum system a program needs.
But. do read the text before you start
typing.

Finally, the little cassette symbol on
listings indicates that program Is
available through our Rainbow On Tape
service. An order form for this service Is
on the Insert card bound In the
magazine.

CERTIFICATION
SEAL

The Rainbow Seal

The Rainbow Certification Seal Is our
way of helping you, the consumer. The
purpose of the Seal is to certify to you
that any product which carries the Seal
has been physically seen by us and that
It does. Indeed, exist.

Manufacturers of products —
hardware, software and firmware — are
encouraged by us to submit their
products to the Rainbow for
certification. We ascertain that their
products are, in actuality, what they
purport to be and. upon such
determination, award a Seal. This lets
you know that we have seen the product
and that it does, indeed, exist.

The Seal, however, is not a "guarantee
of satisfaction." The certification
process is different from the review
process. You are encouraged to read
our reviews to determine whether the
product is right for your needs.

There is absolutely no relationship
between advertising in the Rainbow an6
the certification process. Certification is
open and available to any product
pertaining to CoCo. A Seal will be
awarded to any commercial product,
regardless of whether the firm
advertises or not.

We will appreciate knowing of
instances of violation of Seal use.

Using Machine Language

Machine Language programs are one
of the f eatu res of the Rainbow. There are
a number of ways to "get" these
programs into memory so that you can
operate them.

The easiest way Is by using an Editor-
Assembler, a program you can purchase
from a number of sources.

An editor<assembler allows you to
enter mnemonics into your CoCo and
then have the editor-assembler
assemble them into specific instructions
that are understood by the 6809 chip
that controls your computer.

When you usean editor-assembler, all
you have to do, essentially, is copy the
relevant instructions from the Rainbow's
listing Into CoCo.

Another method of getting an
assembly language listing into CoCo is
called "hand assembly." As the name
implies, you do the assembly by hand.
This can sometimes cause problems
when you have to set up an ORIGIN
statement or an EQUATE. In short, you
have to know something about
assembly to hand assemble some
programs.

Use the following program if you wish
to hand assemble machine language
listings:

10 CLEAR200,&H3F00:I=&H3F80

20 PRINT "ADDRESS:";HEX$(I);

30 INPUT "BYTE";B$

40 POKE l,VAL("&H"+B$)

50 M+lrGOTO 20

This program assumes you have a 1 6K
CoCo. If you have 32K, change the
&H3F00 in Line 10 to &H7F00.

What's A CoCo

CoCo is an affectionate name which
was first given to the TRS-80 Color
Computer by its many fans, users and
owners. As such, it is almost a generic
term for three computers, all of which
are very much alike.

When we use the term CoCo, we refer
to the TRS-80 Color Computer, the TDP
System-100 Computer and the Dragon-
32 Computer, It is easier than using the
three "given" names throughout the
Rainbow.

In most cases, when a specific
computer is mentioned, the application
is for that specific computer. However,
since the TDP System-100 and TRS-80
Color are, for all purposes, the same
computer in a different case, these terms
are almost always Interchangable.

Rainbow Check PLUS

The small boxes that you see accom-
panying programs In the Rainbow
"Check system," which is designed to
help you type in programs accurately.

Rainbow Checl< PLUS will count the
number and values of characters you
type in. You can then compare the num-
bers you get to those printed in the
Rainbow, On longer programs, some
benchmark lines are given. When you
reach the end of one of those lines with
your typing, simply check to see if the
numbers match.

To use Rainbow Checl< PLUS, type in
the program and CSAVE it for later use,
then type in the command RUN and
press [ENTER]. Once the program has
run, type NEW [ENTER] to remove it
from the area where the program you're
typing in will go.

Now, whenever you press the down
arrow key, your CoCo will give you a
checksum based on the length and con-
tent of the program in memory. This is to
check against the numbers printed in
the Rainbow. If your number is different,
check the listing carefully to be sure that
you typed In the correct basic program
code. For more details on this helpful
utility, refer to H. Allen Curtis' article on

TUTORIAL

RAM/ ROM
Upgrade Roundup

By Ed Ellers
Rainbow Technical Assistant

There have been many words written on how to
upgrade the various models of the Color Computer
and TDP System 100 to get more memory and
Extended Color BASIC. With the presence of at least four
different versions of the CoCo's main circuit board (each
changing various aspects of memory expansion), it's easy to
get confused trying to find out how to do the job. At the
Rainbow editorial office, we ve kept a two-page sheet
around that tells how to do a number of different mods.
When 1 found out how different the Color Computer 2 was
from the earlier models, 1 decided it was time for an update
to put all the upgrade information together in one place.

What's The Difference?

When Radio Shack first introduced the Color Computer
in 1980, it started not with version A, as one rnight expect,
but with a board identified as version D. This circuit board
was designed to accept either 4Korl6KofRAM and either
8K or 16K of ROM. The first 8K was for Color BASIC with
the second 8K reserved for future use, but by the time the
CoCo was actually announced Radio Shack had decided to
offer Extended Color BASiC. (Fortunjitely, they did not
repeat the earlier mistake on the Model I where they set up
the unit for 4K of ROM and had to go to an extender board
for the 12K Level II BASIC.) In 1981 Radio Shack decided to
offer the CoCo with 32K R AM ; to do it Tandy modified the
board to use half of the capacity of a set of 64K RAM chips.
Since the modification was rather complex and hard to do in
production, they went to the version E board which could
accept 4K, 16K or 64K RAMs.

In 1982, as the TDP Electronics division prepared to enter
the personal computer market with the System 100, Tandy
developed what it calls the NC board (which is often referred
to as the 285 or F board). This board was designed to meet
slightly relaxed FCC specifications, and used either 16K or
64K RAM chips. The NC board was designed to make
available the all-RAM mode that all CqCos had the poten-
tial for, but which had not been implemented in the earlier
designs. The NC board went into all TDP System 100 units;
when Radio Shack dropped the 4K CoCo, the NC board
began to appear in their units late that year.

''When I found out how different the
Color Computer 2 was from the earlier
models, I decided it was time for an
update to put all the upgrade informa-
tion together in one place.

Because the CoCo was priced quite a bit higher than its
close competition, Tandy decided to redesign the entire
machine into a unit that would cost much less to manufac-
ture. The assignment, making a computer that was much
cheaper than the existing CoCo but did exactly the same
things, would appear difficult to anyone who is familiar with
the CoCo's already efficient design. But the engineers in
Fort Worth were able to do it, partly by getting rid of the
regulated + 1 2V, - 1 2 V and -5 V power supplies with the use
of new single-supply RAM chips in the I6K models of the
new Color Computer 2. This was i^t about the same time that
Radio Shack decided to offer OS-9 and an improved key-
board for the CoCo; the CoCo 2 was initially sold in 16K
versions only and the regular CoCo (which was equipped for
64K, but advertised as 32K) was given the new keyboard and
a white case and renamed the 64K Color Computer.

If you have a Color Computer with a black border around
the keyboard and a RAM size button on top, you have either
a D or E board. If you have a CoCo with a gray border
around the keyboard and a model number ending in A (or if
you have a TDP System 100), you have an NC board; if it
has Radio Shack's **32K" RAM then you already have 64K.
If you have the Color Computer 2, it's a whole new
ballgame.

A Few Precautions

1) Unplug the computer before you start making ^ny of
these modifications. Even though the machine is turned off.

May 1984 the RAINBOW 49

there may still be a small current flowing in the Cocoa's
circuitry, which could cause damage when you start plug-
ging and unplugging chips; there will definitely be 1 20 volts
present on the power transformer, and you could get a very
nasty (not to mention dangerous) shock if you make contact
with it!

heat needed for soldering, but the heat of the bigger irons
and guns (designed for radio, TV repair work) can easily
damage them. A grounded iron (with a three-prong plug) is
helpful, but not really necessary; if you have a cordless
soldering iron, it would be ideally suited for this work.

4K to 16K

"The D and E board upgrades take a
bit of wiring to get 64K . . . the NC
board is not particularly difficult, and
the Color Computer 2 is the easiest of
all "

2) The RAM chips (and, to a lesser extent, the other
integrated circuits in the computer) can be damaged by
static electricity. The new chips you will be installing will
usually be on a black conductive foam pad. Just before you
install them, touch the pad to either the shield (if any) over
the circuit board or to the RF modulator unit's metal case.
(Use the pad to hold the old RAM chips you took out, so
thpy will be protected until you install them in something
else.)

3) Use a soldering iron (not a gun) rated at around 40
watts or less. The components and circuit board can take the

To install I6K RAM in a 4K CoCo (D or E board), you
need only a set of eight 41 16 RAM chips. These should be
rated at 200 nanoseconds or faster (which most are these
days). When you open the case and remove the shield, you
will find the 4K chips in sockets U20-U27. Remove them one
at a time by gently prying them out with a small screwdriver
or nail file; insert a 16K chip in place of each one, with the
notch on one end in the same direction. Now locate two
jumpers marked 4K on one side and 1 6K on the other; one is
next to the 6883 SAM chip (U 10) and the other is between
the two 6821 PI A chips. Change each of them to the 16K
position. With Color BASIC, you should now get a response
of 14631 to PR/NT MEM.

All The Way to 64K

To upgrade a 4K or 16K CoCo to64K, you will need a set
of eight 4164 64K RAM chips, as well as a few feet of thin
insulated wire (wire-wrap wire is normally used, but you can
also use wire taken out of telephone cable). The D and E
board upgrades take a bit of wiring to get 64K (the D version
has to be rewired even to get 32K); the NC board is not
particularly difficult, and the Color Computer 2 is the easi-
est of all. On a D or E board, I would first install the chips
and get the computer going as a 32K unit before doing the
64K modification. (If you have the D or E board, check the
Color BASIC ROM's copyright date; if it's marked (C) 'SO
you will need to replace it. See basic ROM Upgrades
below.)

D Board: This board has only the two jumpers that I
mentioned in the I6K upgrade instructions. After removing
the shield cover, check to see that the jumper next to the
6883 SAM chip (marked UIO) is in the 16K position and
remove the jumper between the two PI A chips. To change
the power connections to the RAM chips, bend up pins 1,8
and 9 of each chip. (With the notched end of the chip facing
away from you, pin 1 is at the upper left, pin 8 is at the lower
left and pin 9 is on the lower right.) After inserting the R A M
chips in place of the old 16K chips, wire pins 1 and 8 of each
RAM chip to pin 9 of that chip's socket. Wire the pin 9s on
all the chips together and connect them to pin 35 (the sixth
pin from the top on the right side) of the S A M chip. Connect
pin 1 2 of U4 to pin 1 6 of U8. Check to make sure that none of
the bent-up pins are touching anything, and that all the pins
are well below the edge of the shield wall. (Skip the next
paragraph.)

E Board: There are five jumpers in this board and two
more jumper locations that don't have jumper plugs on
them. Move the jumper located between U8 and U4 and the
three jumpers next to the keyboard connector to the 32K
position, and check to see that the jumper just below C44 is
set to the 1 6K 32K position. Solder the two pins next to C44
together; find the three pins (marked LOW and HIGH) next
to U29 and solder the LOW pin to the center pin. Cut off one

50 the RAINBOW May 1964

side of each of the capacitors C6 1 , C3 1 , C64, C35, C67, C45,
C70and C48. Replace each of the 16K RAMs with the64K
chips.

With 32K RAM, you should get a response of 3IOI5 to
PRINT MEM {24^11 with Extended Color BASIC). If all is
well, unplug the computer again. Pull U29 (74LS02) and
U 1 1 (74LS 1 38) from their sockets, bend up pins 4, 5 and 6 of
U29 and pin 5 of U 1 1 and reinsert them. Connect pins 6 and
8 of U29 together (pin 8 was not bent up), connect pin 4 of
U29 to pin 5 of U 11, and connect pin 5 of U29 to the pin
marked TPl on the board, The computer should work the
same under BASIC as it did before you took out the two
chips, (To try the other half of the RAM, you will need to
run some program that uses 64K, such as OS-9 or Tele-
wnter-64, and see if it works qs expected.)

Radio Shack 32K: If your D or E board CoCo was
purchased with 32K RAM (or upgraded by Radio Shack),
you most likely have a good set of 64K RAMs in place and
you will only need to perform the 64K addressing modifica-
tionabove. If the LOW-HIGH jumper (on an E board) is set
to HIGH, or if the connections to U4, U8 and/ or U 10 (on a
D board) are different from those given here, you will prob-
ably have to put in new 64K chips because the ones you have
are good in the high half only. If you put in new RAMs,
move the jumper to LOW (on an E board) or change the
wiring (on D).

NC Board: The RFI shield is held in place by lugs under
the board. Pry down the two lugs near the left edge of the
board, then pry the shield loose from the top of the board.
Clip out capacitors C58, C60, C62, C64, C66, C68, C70 and
C72 (these are the nearest of the two capacitors next to each
RAM socket). Change the two jumpers next to U21 and one

above U28 to the 64K position. Solder the two jumper pins
next to U 17 together. Replace the I6K RAMs with the 64K
chips. When you put the shield back on, bend those tabs you
can reach back into place.

Color Computer 2: U nplug the keyboard cable and set the
keyboard aside. Replace the I6K RAMs with the new 64K
chips. Locate the two adjacent holes at Wl next to the HA
chip (MC6822P) and connect them together. Plug the key-
board back in.

With 64K RAM, you should get a response of 31015 to
PRINT MEM {24S1\ with Extended Color BASIC). Unless
something very odd is wrong with your machine, the 64K
mode should now work. Color Computer 2 users should
note that the 1 6K chips that came out of the CoCo 2 are not
41 16s; they are 21 IBs, which use a single +5V power supply
and wiiinot work in earlier CoCos (either as replacements or
for "piggyback'' RAM expansion). In the same way, the
41 16 RAMs cannot be used in the CoCo 2.

BASIC ROM Upgrades

Extended Color BASIC: The upgrade kit (Radio Shack
catalog number 26-30 1 8) consists of the ECB ROM chip and
the Going Ahead with Extended Color BASIC manual. Any
Radio Shack store or dealer can get it for you, though some
sales people may not know that they can sell it without
installation or may be unwilling to do it. The only thing you
have to do is insert the ROM chip in the empty socket next
to the Color BASIC ROM. (ECB does require at least 1 6K of
RAM to operate.)

Color BASIC Revisions: Tandy has released three different
versions of the Color basic ROM, all of which carry the
part number 8040364. Version 1.0 s major characteristics
were that it used a 7-bit format for printer output (and
therefore could not use bit-image graphics on Radio Shack
printers) and that it worked only with 4K and I6K RAMs
(not64ICs). Version I.I (8040364A) allowed theuseof64K
RAM chips and used an 8-bit printer format. Version 1.2
(8040364B) cleaned up a few bugs in the Color basic math
functions, and the extensively rewritten interpreter runs
faster than earlier versions did. As with Extended Color
BASIC, installing the new ROM only involves putting it in its
socket (in this case, replacing the old ROM chip). Socket
numbers vary, but the Color BASIC ROM will always be in
the lower-numbered position of the two 24-pin sockets
(Extended Color BASIC will be in the higher-numbered
socket).

Color Computer 2 Cartridge Port

The Color Computer 2, as mentioned above, uses single-
supply 16K and 64K RAMs. Because of this, Tandy left out
the regulated -f I2V supply, which the disk controller and
X-Pad depended on for power, so the CoCo 2 normally can't
use them (unless you have the Multi-Pak Interface). An
unregulated +I2V source is available, and it's easy enough
to put it on the edge connector where it can do some good.
Locate the four diodes (CRM) next to the power trans-
former. Run a wire from the cathode (banded end) of either
of the two larger diodes (CR3 or CR4) to pin 2 of the edge
connector. This pin is clearly marked, and is on the end at
the back of the unit. ^

EDUCATION OVERVIEW

Out Of Diversity,
An Evolving Curriculum

By Michael Plog, Ph.D.
Rainbow Contributing Editor

From time to time, there are little "guideposts" or signs
about progress in educational use of computers. One
such guidepost is an annual poll of new college
freshmen. The survey is conducted jointly by the University
of California at Los Angeles (UCLA) and the American
Council on Education. Results are based on a statistically
adjusted sample of 254,3 1 7 freshmen who entered two- and
four-year colleges in the fall of 1983.

Among the many topics covered in the poll is one question
of interest to us. It seems that 37.5 percent of college fresh-
men have written a computer program. More males than
females have written computer programs, but not as many
more as expected: 43,6 percent males compared with 31«6
percent females. Students attending universities tend to
have more computer experience than students attending
colleges; and those in private colleges and universities tend
to have more experience than students in public institutions.

There were many findings contained in the survey. If any
of you want to examine the entire survey, you can purchase
the results ($8.25 prepaid) from the Cooperative Institu-
tiondl Research Program, Graduate School of Education,
University of California, Los Angeles, Calif., 90024. The
question for this month relates less to the number of fresh-
men programming computers than to what it is they have
learned during their high school experience.

Because computer education is relatively new in schools,
there is no standard list of educational experiences for stu-
dents. The curriculum for computer education is still evolv-
ing, unlike the curriculum for other subjects in schools.

Most fields of study have a defined area of knowledge that
is more or less agreed upon by scholars within the specialty.
For example, if students have taken a course in biology, it is
reasonable to expect they know about digestion and repro-
duction. Eating is something common to animals, as is
procreation. It is likewise reasonable to expect students
completing a course in mathematics to know addition, sub-
traction, multiplication, and division. A study of arithmetic

(Michael Plog received his Ph.D. degree from the
University of Illinois, the MS^from Memphis State
University, and the B.S.from the University of Ten-
nessee. For his foreign j research language option
required for the doctorate, he naturally selected com-
puter language. Michael currently works for the Illi-
nois State Board of Education as a research and eva-
luation specialist.)

is simply not complete without such knowledge, and more
advanced courses in mathematics have to begin with
arithmetic.

In a similar thought, any student who has taken a course
in government should know the differences between the
Senate and the House of Representatives. Any student who
has taken a course in auto repair should know what a spark
plug is.

Some fields of study are less well-defined than others.
Math and science are traditionally the "hard" sciences, and
as such have a more commonly agreed uppn set of facts for
students to learn. Even in the less well-defined subjects,
however, there are some commonalities. I used to be a social
studies teacher. Students in my world history classes might
have walked away with a different set of facts than those in a
class of some other teacher. It is reasonable to expect, how-
ever, that a world history or world culture class should
contain something on Europe.

Ah, but computer education; that is different from other
fields of study. Consider those college and university fresh-
men who have written a computer program during their
high school career. We can make no assumptions about
what they learned. It might be fair to assume that ipost of the
students wrote a program on a microcomputer, not a main-
frame. Beyond that, there is little that is expected to be
common in their educational experiences. We do not even
know what a "program" is. My first thought (and possibly
yours) is a program in BASIC. However, we might be wrong
in that assumption. Some people consider a set of com-
mands for a spreadsheet or data management software to be
a "program." It is even conceivable that a student and
teacher could consider commanding a word processing sys-
tem to prepare a set of mailing labels and a personalized
form letter as a program.

What we are talking about here is an accepted curriculum
for computer education. Not an entire guide to a course, nor
lesson plans for teachers, but a commonly approved set of
experiences expected of students who have completed a
course of study in microcomputers. In all probability, the
accepted curriculum will not be available in the near future.

The problem is one of leadership. True, many people and
groups are willing to offer leadership to the community of
computer educators. There are few educators willing to
follow each of the self-appointed leaders. It is hard to be a
leader with no followers.

In other fields of education, there are traditional areas of
leadership for curriculum development; not so in computer

52 th« RAINBOW May 1984

education. And it appears that some of the traditional places
for curriculum leadership are not possible to use for compu-
ter education.

First, let's quickly dismiss a few organizations for leader-
ship. The United States Department of Education will be of
almost no help in determining curriculum. This organiza-
tion (and indeed, the rest of the federal government) pro-
vides leadership in areas other than curriculum. By targeting
funds for specified activities, policy is determined. The fed-
eral government can determine that computer education is
something important for schools, but cannot provide cur-
riculum suggestions.

The reasons for this are many. The federal people are very
careful about local control. After all, those local people vote
for the members of Congress. Local control in education is a
powerful argument; one which is not easily attacked by
federal elected officials. The Department of Education does
not provide curriculum leadership in other areas, even man-
dated fields, such as special education.

State education agencies are probably not the place to
look for leadership in curriculum, either. The argument for
local control is just as powerful at the state level as it is at the

''At some time in the future, we
will have an accepted curriculum
for computer education. Until
then, let us enjoy the diversity of
creativity that exists now.

federal level. Also, many state governments do not have
people with the expertise to plan curriculum. Leadership
from state agencies is generally in areas other than curricu-
lum.

Traditionally, curriculum is determined by a combination
of public school teachers, university professors in the field of
study, and textbook authors (who tend to be teachers in
public schools or universities). The forum for these people to
share ideas is typically professional organizations. There are
national organizations for teachers in mathematics, science,
social studies, and many more narrow fields or disciplines.
These organizations have periodicals where experts in the
field present views and ideas, sometimes even entire course
outlines. The organizations also provide materials to teach-
ers and provide reviews on textbooks.

In all the mainstream disciplines, professional organiza-
tions have developed over time, and gradually evolved into
positions of leadership for the respective disciplines. Of
course, they also had several decades (in some cases, centur-
ies) of past tradition to draw upon. Computer education
lacks both the national accepted organization of profession-
als and the long tradition of what constitutes the field of
study.

It is unreasonable to expect educators to agree on the
curriculum of computer education quickly. In time, a few
authority figures may emerge, and some universities will
offer degrees in computer education. National organiza-

tions will develop and grow, and eventually one or two will
assume the leadership position for curriculum.

Until that happens, however, the subject of teaching
about computers will remain a topic somewhat unique to
each school. This situation has positive as well as negative
points. The negative side is that we, as the public, will not be
sure of what knowledge a student has upon completing a
course in computers. The positive feature is that experimen-
tation produces possibilities of quality, which can be shared
with other educators. After a while, the best of what has
been developed can be used by many people, thus sharing
good ideas.

There may be no way to speed the process; we may have to
let the natural course of events happen, then observe the
results. At some time in the future, we will have an accepted
curriculum for computer education. Until then, let us enjoy
the diversity of creativity that exists n<iw,

I have one additional task this month. I must apologize to
you, the reader. In a past article I said that a disk drive in a
mainframe establishment contained a googol byte of stor-
age. That is incorrect. The drive has a giga byte, not a googol
byte of storage. A giga byte is the number I followed by 9
zeros; a googol is the number 1 followed by 100 zeros.
Some of you wrote in explaining that it would be impossible
to build a machine with a googol byte of storage* So, I have
mixed feelings. It is never pleasant to state something in
writing that is simply wrong. On the other hand, I do appre-
ciate people reading this column and communicating with
me about it. So, thanks for writing to point out the mistake.
I am sorry I gave wrong information. I am pleased, however,
that you helped me learn something new.

PRINTER MAINTENANCE

REVIVAL

By Barry E.Becker

The salvation of a gang of dirty old characters
is accomplished by virtue of cleanliness.

^V'had been experiencing a definilel) disturbing difference in the
I definition of the descenders on the lowercase letters on my
^M^Gemini 10 printer. The effect was inconsistent, however, and
had not been noticeable when the unit was new. So I suspected that
something suspicious was afoot with the head,

A call to the local authorized service center confirmed that the
condition could certainly be caused by a collection of dirt on the
print head, and could be cured by lareful!) cleaning it.

The recommended remedy for removal of the residue is iso-
propyl alcohol, followed by application of a very, very light
lubricant.

It is necessary to remove the head from the printer first, in the
case of the Gemini 1 0, it is a simple task. Only two screw s secure the
head in its resting place. After they are removed, the head lifts
straight up out of its mount. A flevible, printed circuit cable goes to
a connector on a small phenolic board below. A plastic tab on the
flexible cable provides a means of grasping the cable and gently
pulling it free with a wiggling motion to the right.

I went through the cleaning process twice. After the first time,
the problem persisted, so I persevered and promptly performed the
procedure again. Before the second round, I looked at the business
end of the print head with a microscope* Apparently transferring
the ink from the ribbon to the head is very tough stuff! A gentle
rinse with the alcohol is not sufficient to remove all of the offending
material.

Teiewriter-64 fC) 1963 by Cognitec

The gunk can be removed by applying the alcohol
with some force or pressure. A rubber syringe or some
similar device should suffice. 1 used a rubber bulb and
teflon tube intended for desoldering. I filled the bulb
with alcohol, much like using a huge medicine dropper,
and forced it (as briskly as I could) over the face of the
print head and into the cavity just behind the face of
the head. An ear wash syringe will do just as well.

Make sure that the alcohol does not attack the
syringe material! Apply a small amount to the surface
of the syringe and wipe it with a white cloth or swab. If
any of the color comes off, do not use it. You must only
'use materials that are not attacked by the solvent,
otherwise you could really gum-up the works.

Several strong, sloshing rinses are necessary to
remove all the gunk. A jeweler's loupe, magnifying
glass, or low powered microscope will reveal the con-
dition of the wires directly behind the face of the head.
If you can see any globs of ink on the wires inside the
cavity behind the head surface, then more washing is
necessary. Do not touch or push on the wires. Let the
alcohol do the work. Force applied to the wires would
probably cause irreparable damage to the print head.

After you are satisfied that the head is really clean,
apply a very small amount of a very, very light lubri-
cant. I used something called LPS 1, which comes in a
spray can. Rather than spraying the head, 1 recom-
mend collecting a bit of the spray in the cap or a small
cup, and applying it to the outer surface and behind
the face with a toothpick, very gently. You may spray
it if you'd rather, but don't saturate it. A little dab'll do
ya. Products like WD-40 or CRC 5-56 will probably
work just as well. Wipe off the excess from the outside
with a clean soft cloth or swab.

Replacing the head on the Gemini is fairly easy. The
only caution to observe is in tightening the screws. Do
no/ apply a lot of force or you may strip the threads in
the mounting holes. Just slightly snug is sufficient. A
dab of clear nail polish applied to the screw heads will
prevent them from coming loose. Reconnecting the
flexible printed circuit cable requires remembering the
way it came out, and slipping it back in the connector
the sanie way. A little wiggling and jiggling may be
necessary. Be gentle.

The procedure described here is specifically for the
Gemini printer. 1 suspect that most printer heads could
be cleaned the same way, but don't take anything for
granted. If you think your head could use a cleaning,
call the manufacturer or local authorized service cen-
ter'and find put whether it's advisable to clean it your-
self, what solvents are acceptable, what lubricants, if
any, are acceptable, and what cautions to observe.

Having stated the preceding disclaimers, let me say
that the joy is not really in the cleaning, but in the
resulting clear, crisp letters that once again pour forth
from the print head,

SCHOOL IS IN THE HEART OF A CHILD

Watching Important
Program Evaluators —
The Children

By Fran Saito & Bob Albrecht
Rainbow Contributing Editors

••School Is in the Heart of a Child*' is for parents of qpite yoiing
children. We want to help you work and play with your thrCe- to
eight-year-old child and learn to usp computers as a joyful family
experience. We want to suggest ways to incorporate the home
computer as another means to encourage your child's independ-
ence, growth, and control over his own life. See the pride on her
face as she directs the computer to do what she with deliberation
selects. See her head gears switch to **on^'as she progresses step-by-
step with your presence and caring direction.

We will explore (we hope, With your help) the following:

• Specific ''teaching** techniques so that the discovery can be
the child's own.

• Critical evaluation of software based on e?(tensive ptaytesting
in family and related environments.

• Additional resources to consult: books, magazines, software
publishers, networks, etc,

• Suggestions for interludes and fun times away froip the
computer (a must!): call the librarian for specific infor-
mation; watch a TV program together and discuss it;
work together as volunteers in a community project; take
a fall (or spring or winter or summer) awareness walk < . *

• Whatever we team from families we work with in Menlo Park
or from you, oiir ireaders. Let's pool our knowledge, Let*s
share our experiences as we alt learn from our children.

We will also provide many small programs you can type in and
use right tiow.

60 the RAINBOW May 1964

Learning is more than just what goes on in a
school classroom nine months out of a year.
Learning covers all the knowledge and under-
standing we gain through reading or observing or
experiencing. Learning is discovery; learning
occurs everywhere. All of us are learning all the
time,

Long Live RAINBOWfest!

We have just returned from RAINBOWfest in Long
Beach. Eleven members of the Dymax family (The Dragons
of Menlo Park) made the pilgrimage and revelled in meeting
and talking with people, cruising the exhibit area, learning
new stuff. Kudos to Lonnie and everyone for a great conven-
tion — it reminded us of the first days of the West Coast
Computer Faire when things were still new and brightly
shining. Long Live RAINBOWfest! We'll be back.

(Fran Saito holds a degree in education from the Ufti-
versity of Hawaii and has taught preschool and ele-
mentary students. She feels her inspiration comes
from Mariko, her five-yeat-old daughter . Well-known
author Bob Albrecht also writes the "GameMaster's
Apprentice" feature for the Rainbow each month.)

agree. Next time, we will include some introductory material
on "CoCo LOGO," or "Color LOGO" as Radio Shack calls
it. In the meantime, we suggest you hurry on down to your
friendly Radio Shack store and get a copy of Color LOGO
(Program Pak or disk) and the following,booklets.

Playtesting^ First Impressions

ComputerKid, USA! puts computers in the hands of kids
in youth organizations, alternative schools, and at home in
order to play test and evaluate educational software in places
that are learner*centered^ instead of teacher-centered. We
now have the following sites.

— Herbert Hoover Boys' Club in East Menlo Park,
California. Boys and girls of many ages.

— Greenoaks Montessori School in Menlo Park. Kids
from three to six years old.

— Our own playtest room. Kids and their parents come
after school to try out educational software.

— Greene Community School, Greene, Iowa. A CoCo in
the elementary school library can be checked out for
home use. Greene is a rural community of about 1300
people.

— Roving CoCos on loan to Menlo Park families who
will playtest software and report on their experiences.

— Roving software on loan to Menlo Park families who
have their own CoCos.

Tim Finger is Director of ComputerKid, USA! He has
been doing this full-time for two years. He begins by trying
programs himself to get the "feel" of the software. Then, he
uses the programs with a bunch of kids and learns more by
watching them. Finally, the software goes to other playtest
supervisors who work with kids and fill out formal evalua-
tion forms. Below is the story of Tim's first playtest of some
items from Radio Shack.

May 1984 th« RAINBOW 61

Jan. 30, 1984. Greenoaks Montessori School. Age: five.

The room is buzzing today when Tim walks in. There are
two nursesdressed in their white uniforms, circulating in the
classroom and asking questions of the children. The child-
ren think it's pretty neat and are very excited. So excited that
it's difficult to calm down when Tim is ready for his first
group and his first game, Star Trap. The object is to trap a
shooting star that is speeding through a maze. The game is
directed to ages seven and older, but part of Tim's purpose is
to see what games can be effectively used by parent and
young child together. Can the age level be brought down
because parent is working with child? The game depends on
manipulation of the joystick. This group of five-year-olds
likes the idea of the game, to capture the evasive star, but
they have little control over the joystick. The right and left
movements they have practiced become totally confused
when the game requires that they be quick and automatic.
The movement goes too quickly for them.

Tim: There is too much play in this joystick and the
responses are slow, sluggish. Another thing I look at are
the color graphics. Is there variation in color? Is it pleas-
ing to the eye? For this game, I would say no.

1 see possibilities for this game, though. For the child
who has more control over the joystick there could be
some benefits: he/she could learn to anticipate move-
ments, to think ahead and could become quite creative in
setting up blocks.

Grobot is the second game Tim sets up. This time he has
two small helpers who have learned to put the cassette in the
tape recorder and to rewind. They all are slowly on their way
to being in control of setting up the computer; Tim is pleased
with their progress.

Grobot is directed to children 10 and older and is about
growing plants in different climates.

Here again the children like the idea of the game and
seeing the plants grow and flower, but for them there are too
many things to watch for and control: pests from above and
below, flowers to be plucked quickly, decisions to be made
by choosing from too many selections.

The names for the plants look and sound strange to Tim.
Bagalabra. Twiskis. Kalidobean. "Why," wonders Tim,
"aren't real plants used with their real names and character-
istics?" Like tulip. Maple. Coconut tree. Would the children
relate more to those names and the concept of ideal habitats
for different plants?

Feb. 7, 1984. Greenoaks. Age: three.

Tim and his helper, Sheri, have been frustrated in the
preparation of this game. Directions in the manual for the
set-up are not precise and they learn, after much effort has
been expended to no avail, that this drawing pad works only
on the older model CoCo. (This is the X-Pad. It does not
work on the CoCo2 unless you add the multipak interface or
slightly modify the CoCo 2. We expect the X-Pad will be
discontinued in favor of a touch pad more like the Koala
Pad.)

this drawing pad, has tobe very accurate. Lots of picture-
perfect graphics would be very welcome.
Tim: Who can type in the letter R?

David quickly seeks and presses. The letter R appears
on the screen. David is almost four years old and is the
hotshot of the group. He understands the directions eas-
ily and responds accurately. He finds U, then N and the
[ENTER] key.

Ready to go, the drawing pad only awaits a drawer.
Tim: Would you like to try?

He asks the three-year-old on the side of him. The child
declines. The child on the other side also declines.
Tim: Alright. Who wants to try this?

David's hand shoots up and he comes over. Carefully
he prints his name on the clean white sheet of paper
covering the grey metal drawing pad.

Tim: Look at the TV screen, David.

A smile of satisfaction crosses David's face as he sees
his name, in rainbow colors, on the screen.

Now Tim draws a circle and straight lines emanating
from it.

"What is this?" he asks,

"A sun!" chorus the children.

He draws what looks like a building within the sun.

"And what is this?" he asks again.

"A house," they say.

"Have you ever seen a house in the sun?"
One child nods with surety. That's David. Most do not
respond. One or two look questioningly at Tim. Tim only

grins.

He erases the screen and then draws four circles one on
top of each other, the largest circle on the bottom, the
smallest at the top.
Tim: "What is this?"
Children: "A snowman."

Tim: "That's a funny-looking snowman. Is he missing
something?"

Children: "A hat. Arms. Hands."

Together he and the children complete their snowman
and while Tim laughs at the lopsided figure, the children
don't find it lopsided at all. That's the way Frosty is
supposed to look, their expressions say.

In like manner, the little group goes through filling in
parts of a car. It ends up finally a fire engine, Tim now
asks, waving the pen, "Who would like to try this?"

He asks Ria. She says that she would, but that she'll
need some help. Tim nods and hands her the pen. Ria
discovers that unless she presses down with the pen hard
enough, her mark doesn't appear on the screen, although
it does appear on the paper. So she concentrates on
pressing down harder and sure enough, her name, too,
appears on the screen. She is pleased at her name in
rainbow colors.

Everyone, teachers and children, likes this drawing pad
concept. Join the Koala Krusade! The possibilities are infi-
nite for young child and parent to create a picture together.
The patterns lend themselves toward beautiful abstract
designs and the rainbow colors are very pleasing to the eye.
No one needs to be an artist, as everything looks good.

In short, this is a creative, fun activity. It is something that
can be used repeatedly with new inspiration. It encourages
development of another level of perceiving — what 1 draw
on this paper appears simultaneously on the screen. While

initially the concentration is wholly on the paper image,
soon the child, while drawing, looks to the screen for direct
feedback. (Excellent preparation for Apple's Macintosh
and other ICON/ WINDOW computers of the future.)

Drawbacks: Cost is high — $ 1 99. Putting in this program
is not that simple for beginners. While our three-year-old
needed practice in holding the pen and pressing down hard
enough, we note that the pad, according to directions, can be
programmed so that only movement of the pen is sufficient
to produce effect.

Feb. 13. Greenoaks. Ages: five through six.

Much to his dismay, CoCohead by Computer Island does
not work with the equipment on hand today, so Tim dregs
up Ernie's Magic Shapes again. (We will try CoCohead
another time.)

The testing with a giggly group of four young lads brought
up the reality of black and white TVs. Not only was it less
vivid and beautiful but the games involving color percep-
tion, of course, do not work (in this case, more than half of
the game choices). For how many people, schools, or centers
out there is this a problem? Is it something that should be
brought to the attention of software people?

The four boys do the game very well. In fact, the challenge
and excitement seem to be lacking. Have they tired of this
game? At this age level, has it no more appeal after they have
done it a couple of times?

Florence, in the second group of children, says, "IVe seen
enough of Ernie, Tim. Let's play something else."

For some of these children, then, the game has already
lost its appeal. For home use, a program must have "staying
power" in order to justify its purchase. Does Ernie's Magic
Shapes have staying power? We don't know yet — what do
you think?

Help!

Help us playtest and evaluate CoCo software. Send us a
stamped, self-addressed envelope and we will send you a
bunch of playtest evaluation forms and directions on how to
use them. Fran & Bob, P.O. Box 310, Menlo Park, CA

Wordsworth

Assign a number score (LS) to each letter of the alphabet,
A through Z, as follows:

A=l

H=8

0=15

V=22

B=2

1=9

P=16

W=23

C=3

J=IO

Q=17

X=24

D=4

K=ll

R=18

Y=25

E=5

L=12

S=19

Z=26

F=6

M=I3

T=20

G=7

N=14

U=21

A word's worth (Wordsworth) is its numerical value,
obtained by adding the values of the letters in the word. For
example:

HOBBIT is worth 8+ 1 5+2+2+9+20 = 56 points
DRAGON is worth 4+18+1+7+15+14 - 59 points
TROLL is worth 20+18+15+12+12 = 77 points

From now on, for quite some time, we will suggest
Wordsworth activities for you and your child. So ... we
must select a dictionary. We choose the following:

■ 'THE SESAME STREET DICTIONARY." Ran-
dom House/ Children's Television Workshop.

Get it at your friendly local book store. If they don't have
it, call Random House toll free: 800-638-6480. Ask for Cus-
tomer Service.

We will send a small stuffed dragon to the first child
(earliest postmark), age three to eight, who sends us the
answers to the following questions. All answers must be
bold face words in ''THE SESAME STREET
DICTIONARY/'

1) What three-letter word has the smallest Wordsworth?

2) What three-letter word has the largest Wordsworth?

3) What four-letter word has the smallest Wordsworth?

4) What four letter word has the largest Wordsworth?

5) What is the first word (alphabetically) to have a Words-
worth of exactly 100?

6) In the entire dictionary, what word has the largest Words-
worth?

7) What is the longest word (most letters) having a Words-
worth of exactly 100?

We hope that parents and children have a wonderful time
browsing through '*THE SESAME STREET
DICTIONARY."

Most of the work and play in answering our Wordsworth
challenge is people work: browsing a dictionary, thinking
about the questions, creating strategies — most enjoyable!
People are well equipped to do this kind of work/ play.

Some of the work is grungy stuff: looking up letter scores,
adding numbers.

Hmmm . . . why not let CoCo do some of the grungy
stuff? Here is our first Wordsworth program.

Look For Words

This program fills the screen with randonrt letters. Can you
find words on the screen? Write down any words you find.
When in doubt, consult a dictionary.

The subroutine in block 900 picks a letter (L$). Lines 910
and 920 decide whether to pick a vowel or a consonant. In
line 130, Nye set the probability of pickinga vowel(PV)at30
percent. In line 9 10. the value of R can be any number from I
to 100. if R is less than or equal to PV (line 920), the CoCo
will pick a voWel in lines 930 and 940. However, if R is
greater than PV, the CoCo will pick a consonant in lines 950
and 960. You can change the probability of getting a vowel
by changing the value of PV in line 130. Happy word
hunting!

Help!

If your home has a kid, three to eight years old, and a
CoCo, please share your experiences in using your CoCo
with your child. If you write to us, please tell us if it is OK to

A tutorial on the use of dot graphics

^Sd very interesting feature of most printers is their abil-
ity to use dot graphics. Unfortunately, this capabil-
ity is not used or understood by most owners of
printers, such as the Line Printer Vll or DMP-100. Sure,
there are a few graphic screen dump programs around, but it
seems that we should be able to do more than just copy what
is already on our screen. 1 suppose the main reason for the
lack of this type of program is the fact that it is difficult to
find anything that discusses dot graphics in a way that a
person who is unfamiliar with the subject can understand.

BOLTYPEis a 32K Extended Color basic program that
allows your Line Printer Vll or equivalent to print with
three new styles: Old English, Italics, and the Futuristic
type. To use BOLTYPE, simply type or load it in and RUN,
For those wishing to modify the program to their own tastes,
1 have supplied a detailed line description. If, for some
reason, you don't want to type in the tedious DA TA state-
ments, you may send a blank cassette, self-addressed
double-stamped envelope, and $4 to Mike Fahy, P.O. Box
943, Havelock, NC 28532.

Before running, make sure the printer is turned on, or the
program will "hang-up" in line 60 until it is. Also, make sure
the switch on the rear right-hand side of your printer is set to
8BS if you are using a Line Printer Vll. This allows the
printer to receive eight bits rather than the usual seven. The
eighth bit is essential in order for the printer to recognize
graphics characters (more on this later).

After all of the data in lines 220-1250 have been read by
lines 110-190, the program will display the menu page,
which begins at 1450. By selecting A, B, or C, you may
choose which type style you desire. Then you will be asked

(Mike Fahy is a student at West Carteret High School
in Morehead City, N, C, and has been interested in
computing for three years. He hopes to meet more
people his age who are also serious about
programming.)

what you would like to have printed. After entering your
message, the program will print your message to the primer
in the style which you requested.

THE OUTER LimiTS

While in the Italic or Futuristic mode, the program will
use the standard characters for any punctuation or numerals
you enter. By using the lowercase mode, you can combine
standard characters with the new style. For instance, by
entering BOLTYPEby mike fahy, the printer will type BOL-
TYPE in the desired type and "BY MIKE FAHY" in stand-
ard uppercase letters. This does not work while using Old
English, however. In this mode, there is no support of any
special characters or numerals.

Exactly how does this program work? On Page 15 of the
Line Printer Vll reference manual, it is explained that in
order to use the graphics mode of the printer, you must first
enter the mode by typing PRINW'2, CHR$(18), which is
done in line 100 of this program.

The codes for the graphics patterns are stored in decimal
128 to 255. In other words, printing any characters less than
128 while in the graphics mode will not show any results
except for the control codes described on Page 1 1 of the
reference manual. The reason for this is because the most
significant bit (MSB), which is the first bit in a graphics
character, has to be 1. The remaining seven bits correspond
to the s^ven dots which form one column. The least signifi-

cant bit (LSB) is the top dot, followed by the next-to-least
significant bit . . . until you reach the second-most signifi-
cant bit, which controls the bottom dot. If the correspond-
ing bit is a I, the dot is printed.

Lost? Well, if you look on Page 184 of the Going Ahead
With Extended Color basic manual, you will find a table
titled "Base Conversions.'^ It*s probably the one you can't
figure out what to do with. In the second column^ labeled
"Binary," you will find what seems to be a mad jumble of
ones and zeros. Actually, these "numbers" represent how the
computer counts. For instance, the decimal value of 128 is
also the binary value of lOOOOOOO, The decimal of 223 is
binary llOIIIII.

So, what does that have to do with anything? Actually, it
has everything to do with it. Okay, let's take a look at a
tiroken down byte c6de.

Decimal 171 equals lOlOlOll. the first or most signifi-
cant bit is I, so we know that it is a graphics character. The
last or least significant bit is also I , which means the topmost
dot is printed. The next to least significant bit is I too,
meaning the next to the top dot is printed. But the next bit is
a 0, so the third dot is not pririted. This process is repeated
until it gets to the next to most significant bit, which is a 0.
Therefore, 171 would look something like this:

LSB

•

7th

•

6th

5th

•

4th

3rd

•

2nd

MSB

•

So, while in the graphics mode, if you told the printer to
print character 171, it would print something like "i".

Note; The MSB will not be printed since it is merely to
determine whether or not the character is a graphics charac-
ter or not.

Fine. So now that I know how to get a certain graphics
character, how do I make my own characters? This is the
simple part. Well, at least it's easier than the rest of our
procedure. To make your own characters, simply combine
the characters yoii already have. For instance, to make an A,
you could conibine decimal 255, which is binary 1 1 1 1 1 1 1 1,
with three 1 37s, which have binary values of 1000 1 00 1 , and a
second 255, to make something like:

•

100 - Enter dot graphics mode

170-190 - Read Italics data

200-210 - Read Futuristic data

istic)

SOFTWARE FOR THE TRS-80* COLOR COMPUTER!

REVOLUTION!

You accelerate hard down a long straightaway, braking heavily at the end
for a sharp comer. You slice smoothly through the esses, and then boldly
keep the power on for a fast sweeper. The Ferrari drifts dangerously near
the edge, but you make a tiny correction in the steering, and you are
through.

The finish line flashes by, and suddenly you are in the pits. The car falls
silent. You see your lap times being held up. Your fmal lap was a new Lap
record! At last, you permit yourself a small smile.

You have mastered this powerful car on a difficult track, driving with the
assurance and precision that comes only from long hours of practice.

You are driving an authentic race car. You arc playing REVOLUTION!

PRINTER UTILITY

So you have a large mailing to do? Too many envelopes
to address? Don't stamp your foot! Cancel your frustra-
tions with ...

By Charles M. Thonen

After getting the Line Printer VII for my CoCo, I
wanted a label program that would print addresses
on the two-up dry gum labels that this printer uses.
All of the programs in the magazines took the easy way out
and just printed the same address on the second label. If only
one label is needed, it is a waste of good labels. I wanted a
program that didn't duplicate labels and had a good looking
screen format Mailabel does both of these and also has the
usual edit, add, delete, search, and functions.

The program is written for a 32K machine and is for a
tape-based system. A PCLEAR 1 has to be entered due to
the size of the CLEAR and D/Af statements in line 120. The
program can easily be changed to disk by the following line
changes.

Change the word TAPE to DISK in line 5020

Delete lines 5020 through 5120

Delete the negative sign in lines 5140 and 5180

Change the PRINW-1 to WRITER in line 5160

Change the word TAPE to DISK in line 6020

Delete lines 6040 through 6120

Delete the negative signs in lines 6160, 6170 and 6200

Mailabel is written with subroutines to help follow the
program logic. The sort routine is a fast machine language
sort from Radio Shack's Microcomputer News (Vol. 4,
Issue 6).

Mailabel comes up with the main menu page on the
screen. There are nine options to choose from. Data can be

input to the program from tape or key-
board. Data can also be added to an existing
file. Records can be edited or deleted. Provisions
are made to save a file to tape. Records can be printed
to the screen and/or printer. This is an unformatted
dump to the printer. Labels, either one-up or two-up, can
be printed. There is also a search and sort feature.

Both Input Record and Add To List will bring up the
Input Record Screen. If a file has already been loaded, the
Input Record Option will not operate. This will stop you
from wiping out the file already in memory. After entering
either a 1 or 3, the Input Record Screen will be up showing
the number of the record tobeentered. Press [ENTER] after
inputting the lines information and the cursor will jump to
the next line. If a particular item is not known just press
[ENTER]. After inputting the last line, hit [ENTER] and a
fresh screen will come up for the next record. Now you can
enter another record, or by pressing the down arrow return
to the menu.

The Edit option will ask for the record number to edit. If
no record number is entered, you will return to the menu by
hitting [ENTER], After entering a record number, that
record will be displayed and an orange cursor will come up
just to the left of the last name in the record. To go to the
next line just press [ENTER]. The cursor will move down to
the next line. By pressing [ENTE R] when the cursor is on the
bottom line the program will recycle to a new Edit screen.
Here you can either edit another record or return to the

menu. If you want to change any line, just position the
orange cursor on that line and press the down arrow. That
line will be removed and a flashing cursor will appear wait-
ing for new input. Hit [ENTER] when the new information
is on the line and the orange cursor will reappear on the top
line, y^fter all corrections are made to the record, you can
bring up a new Edit screen by continuously hitting [ENTER]
until the new Edit screen comes up.

The Delete option will delete any recorcj from the file. If
no recprd number is entered, you will return to the menu.
Enter a record number and the record will appear on the
spreen. If you then decide not to delete the record jtist press
[ENTER] and the program will recycle to a new Delete
screen. If you want to delete the record, hit the up arrow. At
this time you will be given one last chance to change your
mind by answering a sure (Y/N) prompt. By ahswering N
you will be returned to the menu. A Y answer will cause the
record to be deleted from the file and the file updated. The
program ^t this point jumps to the ML Sort, line 1 3000. This
sort will place null strings At the end of the array. It then goes
to the Y pointer reset at line 1 3050 and resets the next record
available to the first mill string that it fin4s. Option 5 allocs
you to print all records to the screen and/ of the printer. This
is an unformatted output to the printer, showing all infor-
mation in each string to ihclude the delimiters required for
program operation. THe down arroNv will i*eturn you to the
menu. Options 6 and 7 save and load the file to and from
tape. Needed prompts are displayed to allow for proper
positioning of the tape. These two subroutines can easily be
changed to tape by making the changes detailed earlier.

Option 7 is the main purpose of Mailabel. It allows print-
ing of either one-up or two-up labels. The first record and
last record prompt have default values built in to someone
just pressing [ENTER]. 1 1 will then ask if you have one-up or
two-up labels. The subroutine at 7000 formats the records
correctly. After the records are printed the program will
return to the menu.

Option 9 brings up a Sort and Search menu. The sort by
last name is the fastest. It goes directly to the ML sort
routine. The other three sorts take longer because they have
to reconfigure the strings before and after the ML sort. The
Search will search the file for any combination of letters and
numbers. If you answer the search prompt With nothing the
program will start at reeord 1 and progress through the
records.

This program has accomplished everything that I set out
to do. At the same time it taught me a lot about string
handling and the use of subroutines.

One last thing, if you can afford a disk, by all means get
one. Being released from the tape system is like moving from
a bicycle to a motorcycle.

When we last saw Fred, he had just finished a face-saving program for
addressing his wife's envelopes, this month he's at it again . . .

Fred's Postcard Whacker

By Don Hughes and Jessie James

(Don Hughes, a writer and consul-
tant, holds two master's degrees, one
in education and the other in counsel-
ing. Jessie James has been engaged for
the past 10 years in the electronic
repair field. He is a bio-medical
equipment technician at Kaiser
Foundation Hospital in Forlana,
Calif.)

Fred slipped past the

screen door and waltzed into the
kitchen, where his wife was

giving the poodle a permanent.

"It's late," she said. "Why have you
been out so late?"

"The most fantastic thing happened to jne," said Fred as
he danced around the room.

His wife looked at him with a jaundiced eye, "What have
you been up to Fred?" she demanded.

"1 was just elected corresponding secretary of the Inland
Empire Color Computer Club."

^'Have you got into something that's going to make extra
work for me?" she asked warily.

"No. Absolutely npt! I have to write an occasional letter,
but my main job is to send postcards to the members every
month to remind them of the meetings." ^

"Then you expect me to write dozens of cards out in
longhand every month?" Fred's wife cackled.

Fred scratched his beard. "1 figured you Could do my
postcards along with the ones you send out to your bridgp
club."

Fred's wife reached for the curling iron, still hot from the
dog\ permanent. She waved it under his nose. "You and
that fancy computer. You keep telling me it saves work, but
as far as 1 can tel), it only makes work for me."

Fred retreated to his computer haven. As he sat down in
front of the keyboard, his mind drifted to possible solutions
to his dilemma. He loved his wife in spite of the poodle and
everything, and he really did want to put his CoCo to work
in useful ways.

Absentmindedly, Fred spun his chair around and began
flipping through his back issues of the Rainbow. As he
leafed through the well-worn pages, he could not remember
seeing an article or ad which offered a program that
addressed postcards, but , . . maybe he had overlooked

something.

When the clock struck midnight, Fred was suddenly awak-
ened from the hypnotic concentration that had engulfed
him. Knowing of no other avenue, he got up to make sure
the door to his study was locked, pulled down the blinds,
then removed his thinking cap from the special hiding place.
He put it upon his head and suddenly the room was abla;.e
with creativity. In an instant he hdd the answer! He would
write a program which would meet the need!

The program Fred created that night is listed below. It
allows you to input a salutation and a closing line (40
characters each). At that point, a blue field appears on the
screen. Both Fred and his wife, and ypu as well, can type
your message within the confines of the field. There's no
need to worry about formatting on the screen because the
program takes care of this while the "One Moment Please
. , prompt appears on the screen.

Once yotj answer the "print" prompt that appears on the
screen, the program automatically prints your message,
properly formatted, pn a standard USPS postcard.

Need to print the same message to everyone in your group
like Fred? Simply answer the prompt in a positive way, and
the same message can be printed over and over.

This program is for a 16K Extended CoCo as listed. If you
don't have an extended machine, just change the "Line
Inputs" in lines 74 and 76 to "Inputs." A friction feed printer
is recommended.

After Fred showed this program to his wife, she gave him
a big hug. "You're my hero," she said.

The First

CoCo

Rockfest

By Fred B. Scerbo
Rainbow Contributing Editor

Editor's Note: The "Rainbow Wishing Well" is a new regu-
lar feature q/'the Rainbow />! which contributing editor Fred
B. Scerbo will share with our readers various programs he
has developed for the Co Co.

If you would like to submit a suggestion for a program
you would like for your CoCo, submit it to Fred, cfo the
Rainbow. We aren*t promising any specific wish will be
granted^ but if the challenge looks good, Fred may list a
program to accomplish your task. Please remember that any
programs resulting from these suggestions become the
property of the author.

Here we are with our third installment of our "Rain-
bow Wishing WelP'and already the wishes are start-
ing to roll in. It will still take several months before
some of these wishes are granted due to the delay time in
publishing, so don't get discouraged. Keep your ideas com-
ing, but please, keep your requests reasonable. (Remember,
this is basic!) While 1 have received nothing but positive
feedback so far, 1 have a feeling that this month's article and
programs will generate more suggestions and requests from
middle school and high school-aged programmers than any
to date. Read ahead and youll see why.

The Initial Inspiration

By now, most of you are aware that I am a high school
teacher of special needs students. While most of my day is
spent with the handicapped, many times 1 will welcome
students from the "mainstream" into my resource room to
work with my students or to give them a chance to try our
Color Computers. Even students who have not had much

background in programming like to type in short programs
which give instant results or feedback, and every day, 1 find
that more and more of these students have CoCos at home.

One such visitor is a freshman named Aaron. Aaron has
had his 64K CoCo for several months now and stops by my
resouce room at least once each day to get new ideas or get
some new insights into what his CoCo can do.

Unfortunately, Aaron still has a bit of an inferiority com-
plex regarding his CoCo. If someone he knows with a
Commodore 64 or an Apple computer shows him a **com'
mercially available" program on his or her machine, he goes
into a tailspin worrying about whether or not his CoCo can
do the same. (Oh, ye of little faith!) Consequently, 1 often
have to show him that many programs that can be written in
our CoCo's Extended Color BASIC can sometimes match or
even surpass what others have to buy for their computers.

One day recently, he came in upset over the fact that he
saw a rival computer's program which would draw a piano
and play "The Entertainer" while the player's hands danced
around the screen. Could the Color Computer do the same
was what he wanted to know.

My reaction, naturally, was, "Of course . . . but who
cares! All the programs Pve been writing and showing you
have been practical. They do something!"

( Fred Scerbo is a special needs instructor for the North
Adams Public Schools. He holds a master *s in educa-
tion and published some of the first software available
for the Color Computer through his software firm.
Illustrated Memory Banks.)

Still Aaron was not convinced about the superiority of his
computer. It was time to pull another gem out of the wishing
well. If he wanted "impressive" programming that did abso-
lutely nothing productive, then that's what I would give him!
(Do you see where the rock 'n Voll fits in yet?)

THE
ROLLING
STDNEB J

Inspiration Number Two

Aaron isn't the only one who comes knocking on my door
asking for ideas or help. Quite often, students will come and
ask me to help them sketch out the symbol for one of their
favorite rock groups. (Usually the request is for AC-DC or
Van Halen, while just a few short years ago, everyone

wanted KISS.) These students will sometimes want these
symbols to use in their graphic arts class where they can
make note pads, letterheads or even silk screened T-shirts.
After having been AC-DCed to death, I figured that there
must be a way I could do this with my CoCo.

As I have mentioned, some of the students 1 have fall into
the ''mildly mentally handicapped'' category. Believe it or
not, they actually do enjoy coloring, much like one would in
a coloring book, but they are too old for such things. Many
times, I would help them draw rock posters which they
would carefully decorate. Maybe this effort on the CoCo
could also help me keep on top of this demand for coloring
materials for some of my students.

One Final Inspiration

Several weeks ago 1 had the chanceto view a video broad-
cast of the US Festival, which was put together by Apple
wizard Steve Wozniak. If the Apple computer could have a
rock festival, why not have one for the Color Computer?
Since we couldn't have a real one right away, I figured we
could hold one inside the guts of the CoCo.

The Wish

With all of this input, what kind of wish would I be
granting? To put it simply, I would have to come up with the
first real rock 'n' roll Color Computer program. The wish
would be granted in two parts. The first would display some
of the most colorful graphics I could generate on the CoCo
which would be the logo or symbol for some of the most
popular rock groups around today. This program could be
used simply to impress your friends as to what your CoCo

can do. (Okay, Aaron. Ask your friends if their computers
can do that!) The program could also have a "party value"
which we will discuss later.

The second part of the wish would be a program that
would take these same graphics and generate a black and
white graphic, which could be dumped to a line printer when
used in conjunction with a graphic screen dump program
(not includecj here). Thus, by using my Okidata 82 A printer,
I could generate the pages of a rock *n' roll coloring book
and have coloring sheets for my students at the flip of a
switch.

So, h^rc they are!

As I promised, the first program does nothing productive.
It just draws some very impressive rock 'n' roll graphics and
sits there. The second listing, the Rockfest Coloring Book, is
slightly more productive, if you consider coloring pro-
ductive.

If nothing else, the programs are fun\

Inside The CoCo Rockfest

Imagine a rock festival with some the biggest names in the
business. Who would you include? For the First CoCo
Rockfest (you mean there will be others?) I selected eight
rock acts with attractive symbols that would not drive me
crazy as they were drawn out in basic. The groups suggested
by the high school students 1 sppke with included the Rol-
ling Stones, Asia, Quiet Riot, Z Z Top, Van Halen, Yes, 38
Special, and, of course, AC-DC. While Listing I is for 32K,
fear not. I have designed this program so it can be broken
into smaller programs for each group. Therefore, those of
you with 16K Extended can go to the part of the listing and
just type in the line for the group you wish to draW. The main
program has a menu and a title card which actually lowers
the curtain on our stage which is fun to watch in and of itself.

A WORD OF WARNING!

If you do try typing in just parts of the listing, be sure to
include: 5 PCLEAR8 or the program may crash. Those of
you who have typed in some of my other programs will be
familiar With the fact that I like to DRA Won a graphic page
out of view and then PCOPY the results to the screen you
are viewing. Rockfest incorporates thistechniquealthough 1
have kept the screen turned on part of the time so ybu can see
How the images are formed. Since PC LEA R reserves extra
graphic pages, you can take advantage of this hidden draw-
ing technique. If you were to l^ave out the PCLEAR8,
normally, yoii would just get an?FC Error. However, some
parts of the program use PCOPY io pages not yet displayed,
so if you were to leave out the PC LEAR statement by
mistake, the PCOPY commdnd would try to write the gra-
phic^ on top of yoiii" basic program, causing it to crash in a
non-retrievable way.

Therefore, if you are going to try to use parts of these
graphics, be sure to include 5 PC LEA R8 as your first line. I
Hdv^ included it at the end of the listing accessed by a GOTO
to keep you fi-oril running the program before it is all keyed
in. (Now would be a good time for Rainbow On Tape!)

If you just use parts, you will also have to include; 6
ft=3:R$="C3*\ so as to insure the use of red in PMODE4.
You may have to press [RESET] to get thfe right color. (For
example: On the ftolling Stones, who wants a blue tongue?)
You could also change both thi-ees to twos in this new line 6
to get the same result.

The completed prograrri actually solves this problem for
you by printing a row of A's and B's at the bottom of the
screen. You may activate the program from the title card by

pressing the red-colored letter (A or B). Lines 80 and 82
solve the color shift problem without having to press the
[RESET]. This helps get around your color TV's inability to
control the display of red and blue.

In the 32K version of Rockfest as listed, after pressing the
A or B key, a menu will appear. You need only press the
letter which corresponds to the group you wish to display.
The graphic will then be drawn before your eyes in a fashion
which will convince even the most obstinate doubting
Aaroris, 1 mean Thomases about the powerful graphics
onboard ydur CoCo.

Want to really blow their minds? Add this line: 7 A UDIO
ON: MOTOR O/Vand then RUN the program with a prere-
corded cassette tape of one of the groups listed. Press
[PLAY], and the music should come ripping out of your TV
speaker with these rock 'n' roll graphics. (Van Helen's
"Jump" will beat "The Entertainer" any day.) Yod can even
have these graphics displayed on your TV while playing
your stereo at a party with friends. Sure, it's not MTV, but
it's the next best thing.

You may be wondering why 1 haven't suggested that you
simply use the Rockfest for graphic output to your line
printer.

There are several reasons for this. First, some machine
language drivers might crash with the PC LEA Red graphic
pages. You will have to try theitl to see if they will work for
you. There are many screen dumps available in ads here in
the Rainbow, and some have even been listed. The one I use
iisually crashes with the extra pages.

Secondly, I wanted a graphic screen dump which would
not be solid print as these displays would. Don't get me
wrong.These images will look great even with a line/dot
matrix display of the colors. Since I was looking for graphics
which could be colored in with felt tipped markers, I decided
to make a second version called The Rockfest Coloring
Book (Listing 2).

The Coloring Book

This program recreates the saipe graphics, but in a strict
black a nd white representation suitable for screen dumping.
The program should fit in your 16K machine, but if you have
trouble with memory, delete some of the few remaining (')
remarks.

This listing does not have the stage title card, but it does
have a menu. When you select a graphic, you may return to
the nienu by pressing[ENTER], just like on Rockfest. If yoU
wish to screen dump the contents with a machine language
program, then press [BREAK] and load in your screen
dump program. Don't worry! Your graphic will remain
intact.

The screen dump I use creates an image on a full 8 by 1 1
sheet of paper which makes it ideal for coloring. The screen
dump you use may allow different sizes so you can be the
judge of its uses (pasting on book covers, lockers, framing,
etc.). I think you will find youngsters of all ages enjoying the
results, regardless of what they do with the paper graphics.

Other Uses?

Remember last month's screen quiz programs. I men-
tioned that the Extended BASIC version could include a
graphic reward starting in line 900. If you wish to use any of
these graphics as a reward, then simply delete all lines before
and after each labeled section for a given group. If you use
the Rockfest versions, be sure to PCL£AR as I warned
earlier.

May 1984 the RAINBOW 93

Once you have the lines you want to use isolated (that is,
all the lines before and after are gone from memory), type:
RENUM 900 JO J and press [ENTER]. The program lines
will now correspond to the required location in the screen
quiz program. You may now MERGEihe two programs as
one, either using the disk command MERGE, or a cassette
merge program such as those listed in previous Rainbow
issues. The IN KEYS line at the end of each graphic should
be changed so that the line number after the word THEN is
changed to RETURN. Voila!

You may even use the Coloring Book versions for merg-
ing, which do not require a PCLEAR. This would be advis-
able if you only have 16K.

Feedback

So far, judging from the reactions of the middle and high
school students who got a sneak preview of Rockfest and the
Coloring Book, both are a smashing success. (The word
awesome is usually used!)

Already, plans are underway for Rockfest 11. A few of the
graphics are already half done. (My younger cousin David
and his best friend Eric have been hinting at using groups
like OzzyOsbourne, Motley Crue, Iron Maiden, Black Sab-
bath and a host of other "heavy metal" groups. My own
personal choices would include the Beach Boys or Elvis
Costello, while my dear friend Zelda will probably force me
to include her friends. Village People, under threat of never
giving me any more of her famous lasagna.) Pm sure many
of our high school-aged readers will also have some
suggestions.

In the meantime, keep those ideas coming and enjoy your
rock 'n' rolling Color Computer.

SOUTHERN SOFTWARE SYSTEMS

THE SPREADSHEET ZAPPER NEW POWER FOR YOUR COCO

THE SPREADSHEET ZAPPER bridges the gap between the great computational power of Radio Shacic's Spectacuiator and high quality graphical
displays. A picture is worth more than 1000 numbers!

Imagine being able to easily display all your carefully created Spectacuiator data in the form of outstanding bar graphs, pie charts, and line graphs.

The SPREADSHEET ZAPPER converts those nasty Spectacuiator data files (ROM PAK or Disk) to data files that are 100% compatible with Southern

Software Systems' graphical display programs-The BAR ZAPPER, THE PIE ZAPPER, and THE GRAPH ZAPPER.

Now you can have the best of both - The complete flexibility of a spreadsheet program to do your computations and the use of high resolution graphing
for display of your data.

Compute your Income and expenses; perform statistical computations; analyze the stock market; all using Spectacuiator, then display the results using a

bar graph, pie chart, or a tine graph - very Impressive!!
* Don't limit yourself to endless rows and columns of confusing numbers— forget special purpose plotting programs, get total flexibility.
> ''Authors of commerically oriented pmgrams should beg, borrow, or steal one of the Instructl^^ RIGHT WAY TO DO IT."

The Rainbow, Oct. 1983.

"I was more than satisfied with Elite«Word. Before I started the review, I thought that it would be just another
program that would copy most of what others had done and add a few whistles and bells. After the review, I
would not hesitate to compare it with the two best selling CoCo word processors. And my comparison places It
at the top of the list." - A. Buddy Hogan, Rainbow

Creating Random
Name Files

By Bob Albrecht & George Firedrake
Rainbow Contributing Editors

This time, we present a program you can use to make a
file of random names, using any consonant-vowel
structure you choose. When you run the program,
first you see briefly:

NAMES TO TAPE

This is on-screen momentarily while the CoCo is opening
a cassette file for output. Of course, you first position a
cassette in the tape recorder and press the [PLAY] and
[RECORD] buttons — before typing RUN. Next you see:

NAME STRUCTURE? I

Typea C-V (consonant-vowel) structureand press [ENTER].
Here is what happened when we did it.

NAME STRUCTURE? CVCVC
GODAK

TO SAVE NAME, PRESS "S''
FOR ANOTHER NAME, PRESS SPACE
FOR NEW STRUCTURE, PRESS "N"
TO CLOSE FILE, PRESS "C^

You now have four options. Do you want to save the
name GODAK on tape? If so, press the "S" key. Want
another name using the same C-V structure? Press the
[SPACE BAR]. Want to try a new name structure siich as

(Bob Albrecht and George Firedrake are two of the
most prolijic authors in the microcomputer world
today. Specialists in writing for beginners, they are
authors of numerous books, including TRS-SO Color
BASIC.)

CVCV or VCCVCV? Press the "N" key, then enter the new
name structure. When you have all the names you want to
save, press the "C" key and the CoCo will close the file.

Here is a block-by-block description of the program.

Block 1000 briefly prints NAMES TO TAPE on the
screen and opens a cassette file for output. The file is
called NAM ES. If you are using Color basic, change line
1020 to:

1020 OPEN "O", "NAMES"

You may wish to rewrite block 1 000 to include directions
telling the user to position a cassette and press the
[RECORD] and [PLAY] buttons on the tape recorder.
See our SCAN CHARACTER FILE program in the
March 1984 issue of the Rainbow.
Block 1100 asks for the NAME STRUCTURE (conson-
ant-vowel structure) and assigns it to the variable NS$.
Block 1200 calls a subroutine to make one name and
prints the name at screen position 64.
Block 1300 prints the four options on the bottom four
lines of the screen. Rememberto include the semicolonat
the end of line 1340. Without it, the screen will scroll.
Block 1400 looks for a single key response (S, space, N or
C). All other keys are ignored. If you press one of the four
keys, the CoCo moves on to the appropriate block; if you
press any other key (except [BREAK]), it simply repeats
its request because of the ELSE 1310 in line 1450.
Block 1500 writes the value of NAMES to the cassette
buffer. It also puts a message on the screen at screen

position 128 telling you it is saving the name. Line 1540
clears this message from the screen. CHR$(30) means
''Clear to the end of this line." After saving the name,
block 1500 sends the CoCo back to block 1300 to get
another user response.

Block 1600 closes the cassette file. If you are using Color
BASIC, change line 1610 to: 1610 CLOSE #-1.
Block 1700 is a subroutine to make a name and assign it
as the value of NAMES. First, NAMES is set equal to the
empty string Then, the FOR , , . yV£A^rioop scans
the name structure (NS$) letter by letter, looking for the
letters C or V. Each time it finds the letter C, it calls the
ADD A CONSONANT subroutine. Whenever it finds
the letter V, it calls the ADD A VOWEL subroutine.
Letters other than C or V are ignored.
Block 1800 is a subroutine to add a consonant to
NAMES. Lines 1820 and 1830 select a random consonant
from the string C$. Line 1 840 appends the new consonant
to the right end of NAMES.

Block 1900 is a subroutine to add a vowel to NAMES.
Lines 1920 and 1930 select a random vowel from the
string VS. Line 1940 appends the new vowel to the right
end of NAMES. Note that we include the letter Y as a
vowel. Thus, names such as KOMYN or DYMAX are
possibk.

We leave to you the task of writing a program to read and
display names from the cassette file of random names —
well, "selected" random names — selected by you. You can
do this in many ways.

• Read one name and display it. Press [SPACE BAR] to
get another name.

• Read and display several names. Press [SPACE BAR]
to get another bunch of names.

• Read only names having a specified name structure.
For example, read only names with the structure

cvcvc.

Since we have no reader response to our cassette file
tutorials and programs, we assume you people out there are
not much interested in cassette files. So, next time we will
move on and begin a slow tutorial sequence on disk files.

TAIPAN: Your Own Contextual Computer Game

In the early days of the TRS-80 Model 1, we were privi-
leged to play a simulation game called Taipan, written by
Art Canfil. Taipan easily makes the top ten of all computer
games we have played in the last 29 years.

So, a few months ago, we begged, implored, and down-
right coerced Art to write a book showing people how to
write contextual computer games, using Taipan as the
model. Art agreed and began writing the book, with the help
of two high school students, Jim McClenahan (Dragon-
Kong)'dx\6 Karl Albrecht (DragonNewt). As Art puts it, "To
the Dragon, who dragged us and dragooned us until we
wrote this book. And to Elder Brother Wu, as a representa-
tive of financial realities. If the Dragon was the carrot, Wu
was the stick . .

What is a contextual computer game? The authors say,
"Home computers make possible a type of electronic game
which is less based on exercising the reflexive speed of a
person's brain stem than upon exercising the wonderful gray
matter with which humans think. Some of the best of such
games are those in which a complex environment is simu-
lated by the program, and the player interacts in a 'lifelike'

manner with that game environment. We call these complex
environmental computer simulation games contextual com-
puter games.''

The first book will be our favorite computer, the CoCo. It
will then be paraphrased for other computers: Commodore
64, IBM PC/r, possibly the Apple. TAIPAN: Your Own
Contextual Computer Game is intended to give the CoCo
user three things:

1) an understanding of some fundamental principles of
game design;

2) an historical understanding of a particular game con-
text (in this case, the turbulent China trade of the
1800s);

3) a step-by-step approach to actually writing a game in
BASIC using points 1 and 2 above, including the actual
program lines needed to provide a complete contex-
tual computer game.

The authors hope that this book will provide the reader,
not only with an enjoyable game providing many hours of
entertainment, but that the reader will become interested in
the game's historical background as well. And hopefully, the
reader will be inspired to design original games based upon
other historical or fantasy contexts.

Next time. Art Canfil will join "GameMaster's Appren-
tice"and we will include excerpts from his book-in-progress.
May you live in interesting times.

This One's
A Piece Of Cake

By Joseph Kolar
Rainbow Contributing Editor

The family that computes together, stays together. Let
this be the thought for today.
Two months ago, my daughter joined the ranks of
CoCo owners. To create her very first program, she used the
theme of her husband's upcoming birthday. Curious to see
how she was progressing and eager to see her creation, I
suggested that she mail me a copy. I would critique it.

Copy LISTING! exactly. Look it over. Then, without
elaborating or expanding it, correct any errors. Center it to
give it a pleasing appearance. Alter and adjust the program
to enhance it. This is your chance to show off your own
progress in programming.

Do this before you read any further or before you key in
USTING2. See if you can find all the things that could
stand a little modification.

Before keying in LISTING2, follow along with me and see
one way to approach the problem. After making each
change in LISTING!, you may RUN the program to see
what you have done.

CLOAD^'LISTINGr* diXid RUN. The first thing that
comes to mind is that the first panel needs to be pushed
down for vertical centering. Since PRINT@ was used in
lines 2, 3, and 4, it does no good to add :PRINT:PRINTto
line 1.

Without disturbing the contents of the three line heading,
it was simpler to add -f 64 to the line locations in each of the
three lines.

It looks neater if the space after W A in line 4 was changed
to a period.

"iPRINT" was added to line 5 to insert another blank row.

You may have made the change differently. You may have
dropped the heading down another row; pushed up line 8 to
center it tightly in the middle of the screen. The important
thing is to make the display visually attractive.

A sentence or paragraph looks neater if it is indented.

(Joseph Kolar is a free-lance writer and programmer
dedicated to proselytizing for computers in general,
and the CoCo specifically,)

116 the RAINBOW May 1964

Two spaces were inserted after the first quote mark of line 6
to move the line to the right. Two spaces were deleted after
the word "BY" to realign the sentence. If this step wasn't
taken, a word would split and carry over to the next row.

A space was inserted after *TRESS" in line 8. The line of
text was centered by inserting nine spaces after the first
quote mark.

The next panel required a little work. The text is all
bunched up in the upper-left corner. All that blank area is
crying out to be utilized.

Either after CLS in line 9 or at the very beginning of line
10, add PRINT:PRINT:PRINT:PRINT Use a beginning
if using line 9 or an ending if inserting it in line 10.

It is not good practice to begin a line of text at the left
margin. Allowing for a long name to be input, indent one
space after the opening quote mark of line 10.

The W/'C/r statement will print a question mark. Thus,
"?"at the end of the sentence is redundant. Delete it. Insert
your first name and press [ENTER].

Indent line 20 about nine spaces by inserting them after
the first quote mark. This line must be left of center to allow
for the possibility of a long name. Since this is a surprise
theme, add at the end of line 20.

Indent line 30 one space as you did in line 10. Delete the
redundant question mark at the end of the sentence. Enter
your age and press [ENTER].

Looking over the resultant panel, we see that the text
could be pushed down one more row for better vertical
centering. Being lazy, rather than relocating each of the
three lines, I decided to add a line of text. What suggested
itself was "Well, 1 have news for you." This leads more
smoothly into the following panel.

At this point, common sense would say RENIJM40J!, 10,
but to keep the same line numbers in both listings, common
sense will not prevail. Don't renumber!

Instead, open up line 3 1 . DELS! and insert "CLS" at the
beginning of line 32. Insert a new line 31 — 31 PRINT-
PRINT nVELL I HA VE NEWS FOR YOU!'' Did you
remember to leave blank space after the first quote mark?
Three spaces were used so that the line would be horizon-
tally centered.

Rather than jumping to the next panel, we will catch our
breath and use a time wasting routine to give us time to read
and digest the text. Add :FORZ= I TO 2000: NEXTio the
end of line 31.

The next panel looks very good. It must be oriented to left
of center to allow for a possible long name.

Change the comma to a space in line 36. Add an exclama-
tion mark at the end of the line so that it will appear after the
name. 1 think a comma would be appropriate following
HAPPY BIRTHDAY, but to save an extra space for a long
name, leave it out.

The song flops right into the "cake" panel. Insert 40 FOR
Z = 1 TO 1 000: NEXT for a less abrupt transition.

It bothered me that we called for an input in line 30, but
failed to use it. What use could we have for the variable A
that indicated the age? Determined to use that variable, it
was envisioned to label the cake with the age neatly centered
under the candle.

Studying the cake panel, the candle might look better if it
were on top of the cake instead of being embedded in it. It
also appeared to be a wee bit off-center.

A little trial and error was used to alter the cake and
candle. Changing the 47 to 48 in line 50 made the cake wider.
Changing 15 to lj6 made it lower. The candle, line 70, was
moved to the left and pulled out of the cake by changing (3 1
TO 34) to (30 TO 33).

Now, the age variable. A, could be moved under the
candle. More trial and error work was involved until the
correct PRINT@ location was found. Insert 60 PR/NT@
302,A;.

The location 302 was a compromise. A one-digit age made
it slightly off-center. A two-digit age was properly centered.
You can't have everything. Working on the assumption the
kids, nine and under, would not be critical, 1 opted for the
two-digit location.

The cake is well-centered and nicely proportioned. The
candle flame could use a little work. It could be lengthened
to become more prominent.

To lengthen the flame, add :SET(32A8)\o line 220. Add
:RESET(32,8) to line 230. That isn't bad! To give it even
more realism (as if a slight draft was causing the candle to
flicker), add :SET(31A8) to line 220 and :RESET(3l,9) to
line 230.

Finally, inserting a time-wasting pause, 235 FOR Z = I
TO 1 00: NEXT slaves down the flicker.

If you haven't done so, key in LISTING2 and RUN. It is
substantially a carbon copy of LISTING L The integrity of
the program wasn't altered; only the presentation.

The next time somebody in your family, or a friend, has a
birthday, just CL0AD"LISTING2*\ sit the birthday boy/
girl at the keyboard and let him/her RUN it. I am sure they
will get the message. Anyway, you have a little program,
with the permission of newcomer, Betty Ann White, to add
to your repertoire.

You may have gotten a few ideas of your own from
following this half-baked debugging session. Work your will
on LISTING2 and alter it to your heart's content. Jazz up
the cake. Put more pizzazz into the text. Add color. Modify
or add sound. You are the boss!

If you come up with something interesting (1 am sure you
will), and are inclined to share it, send me a listing of your
creation.

You saw one way to finalize a program. You did a little
debugging. You saw the creative process in action. It is
hoped that you got some ideas of your own as you systemat-

ically worked over LISTING!, It should have been a fun
time. You need not be afraid to fool around with a program.
Make sure you keep a backup copy of your listing so that, in
case it gets zapped, you can start again.

What was the thought for today again? Oh, yes! The
family that computes together stays together . . . and has
more fun. .-.<«<S»

CoCo Widows

By Susan P. Davis

Anew term has cropped up: "CoCo Widow/' We all
know about football widows and golf widows. Now,
it seems, countless women are sitting alone due to
the amount of time their men are spending with the Color
Computer. One Rainbow advertiser has very cleverly capi-
talized on this pathetic situation by offering **CoCo Widow"
needlework.

My favorite anecdote comes from a member of the
Columbus and Central Ohio Color Computer Users Group.
This man was working relentlessly on a program. He
designed it, wrote it and debugged endlessly. Finally, at 2
a.m., it worked. Eureka! He dashed upstairs to share the
sweetness of this victory with his wife. He shook her awake
and babbled excitedly and proudly. She opened one eye,
gave him an icy stare, grumbled "Who cares?" and indig-
nantly turned over and went back to sleep. He was crushed.
When 1 spoke with her later about the incident, she told me
that she bitterly resented the computer and that it takes her
husband's time away from her and the children. When I
asked her if her husband couldn't show her what the compu-
ter could do and how it could help her, she retorted, '^Unless
it can run the sweeper, there is no way it could help me at
all."

Another fellow bought a Color Computer and set it up in
his bedroom because that's where the television was. To do
this, he shoved all of his wife's knickknacks off the double
dresser and replaced them with the computer, tape recorder,
a few cassettes and some note pads. After a while, the tape
collection grew. It no longer fit on the dresser and it looked
just awful. So, this guy emptied all of his wife's clothes out of
one drawer and filled the drawer with tapes. He then stuffed

levels. She is also a C. L U. with seven years experience

her clothes into other drawers and almost succeeded in
closing them. The next day, that couple bought a new televi-
sion for the bedroom, allocated the old set for computer use
and gave the husband his own space — the former sewing
room!

No wonder there's resentment! Even from women who
are gradually learning to use the CoCo for word processing
or to help the kids in school. They told me that the difference
is that football, baseball, golf, etc., all have a season that is
eventually over. The Color Computer can be turned on any
hour of the day or night — and frequently is.

Another reason for the resentment is that many women
feel that they don't *'understand" the computer. It makes
them feel dumb and uncomfortable. A simple analogy might
help here. Just as one does not need to understand how
electricity works in order to flick on a light switch, one does
not need to understand the Color Computer's circuitry in
order to have a good time with it. Just view the CoCo as
another household appliance, as a tool which makes ^ task
easier to perform. That task could be producing mjailing
labels, finally organizing that record or stamp collection,
printing off 10 originals of the same resume or keeping the
children occupied. Really, all you have to understand ijs how
to turn the computer (and other hardware devices) oh and
off, how to insert the appropriate tape or disk ancj hbw to
load the software. This is not as complicated as pressing all
the appropriate buttons on the latest model Lady Kenmore
washing machine just to do a load of laundry.

Lots of the women I speak with seem to be turned 6ff by
"games." They use "games" as an?excuse not to u$e the
computer. They do recognize the educational value pf the
Color Computer, and we'll discuss this next mont^.

I have asked some women if they would consider using the
CoCo to perform a small, practical task; balancing their
checkbook, for example. Some told me that they prefer to
balance the checkbook with a calculator. Another simple
task is paying the monthly bills. Several of these wonlep use
their push button phones to use th^ pay-by-phone feature
offered by their banks. They said they might be interested iii

their bills for them. So the program listing at the end of this
article shows how you can use the Color Computer to help
you bank at home.

We got the idea for this program from CompuServe. They
had a similar program for use with another computer and
modem.

Our BA NKER program requires a 1 6K ECB Color Com-
puter, Hayes SmartModem and a Huntington Bank Pay-
By-Phone account. The program is easily modified for other
modems and other banks with the pay-by-phone feature. It
allows easy and convenient use of the Pay-By-Phone service.
The computer transmits yoyr account and code information
using touch tones. A menu of accounts is displayed to allow
you to choose who to pay, how much and the desired pay-
ment date. This is a very practical use of the Color Compu-
ter. I hope that some of your CoCo widows will give it a try.

Load and run BANKER. The SmartModem must be
powered on. At the first prompt, enter your secret password.
To practice, just hit [ENTER]. The primary menu will be
displayed.

The up and down arrow keys are used to position the
cursor block to the desired menu item. Generally, the cursor
will be positioned for you following the execution of a menu
item.

Hit [ENTER] when the cursor is on the menu item you
want to select.

If the [CLEAR] key is hit, is sent to the bank's

member on how they came into the
computer field, an open discussion was
held with the audience.

Out of the discussion came some yery
important point$. More women are Jii^:
terested in computers today but few
belong to a club. A woman whose hus-
band has a computer feels fodli&h %iVr
ingabout programming techniques from
him. Alsb, women get little time to gain
the same knowledge their spouse has, as
he is always using the computer. It was
strongly recommended that women get
their own computers and learn for thm-
$ejves that they can't break qr hurt a
computer by touching the wrong key.

There was a fraction who were defin*
itely afraid of the computer. They
thought they might break it by typing
the wrong key^ that you had to know
math to use it, and Ihey weren't sure
they could learn to program* Computer-
ization threatens them in their jobs, they
said* because if they didn't learn about
computers they would be left out. At
home, their husbands or children are
spending all th&ir tiine with the eom-
puter.

It was pointed out that the great thing
about computers is that you don't need
to know anything about them to use
them. They are a tool, like the micro-
wave in the kitchen or the TV in the
living room. As with any new tool, you
need to learn a few things. You need to
learn to. turn them on and load a
program.

' Software companies around the coun«
try are producing quality, user-friendly
programs for many applications. Prob-
ably the one most used by everyone is a
good word processor. It can be used for
letters or bulletins or writing articles or
children's term papers , , . the list can go
on forever.

My feeling from the imput of the
panel and audience was that women can
bring much to the computer revolution,
but they will need to get involved and
learn to use their computer just like any
other tool.

Looking At LOGO
From BASIC

By Don Inman
Rainbow Contributing Editor

You may have noticed that the title of this department
has changed from Using Graphics to CoCo Graph-
ics. All previous articles in the series have been con-
cerned with creating graphics through Extended Color
BASIC. In the next few issues, I will be presenting some
material on Color LOGO, a language that may be new to you.
Due to the change in content, I felt a change of title would be
appropriate.

Dale Peterson's friend. Uncle Bert, has been greeting you
for several past issues of the Rainbow with his discoveries of
Color LOGO. Many of you may have attended one of the
LOGO seminars at the Fort Worth or Long Beach RAIN-
BOWfests. Whatever your degree of interest in LOGO may
be, I hope you enjoy this series containing a look at Color
LOGO through the eyes of BASIC.

There are many differences between creating graphics
through Color logo and through basic There are also
many similarities. Color LOGO programs are made up of one
or more blocks (or modules) called procedures. The first
examples will consist of only one procedure. LOGO pro-
grams can be made very readable through indentation and
grouping of lines into logical functions. There is no need for
line numbers as the lines are executed in the order of appear-
ance. Hence, the dreaded, much-abused, and often confus-
ing GOTO statement is unneeded and non-existent in the
language.

Graphics in basic are created by drawing between spe-
cific X, Y coordinates on the screen. Color LOGO differs in
this respect by creating graphics by movements that are
relative with respect to the current position and heading of
the image of a "turtle'' on the screen. The turtle is moved by
the commands FORWARD and BACK. Its heading is
changed by turning to the RIGHT of LEFT. The following
examples demonstrate and explain some of the differences
between Color LOGO and BASIC.

Suppose you wish to draw an equilateral triangle (all sides
equal) at the center of the screen. Equilateral triangles have
interior angles of 60 degrees.

(Don Inman is the acknowledged master of micro-
computer graphics and the author of a large number of
books. He has been working with Color LOGO since it
was introduced. With this issue, his column now
becomes a blend of graphics produced by both Color
LOGO and Extended Color basicJ

Figure 1
EquHateral Triangle
(alt sides equal; all angles - 60 degrees)

Let's look at BASIC first. Suppose we wish the sides of the
triangles to be 20 units in length. The center of the screen, for
both languages, has an X coordinate of 128 and a Y coordi-
nate of 96. Since Basic's DRA W command is limited to
drawing lines at multiples of 45 degrees, we must turn to the
LINE command and draw from one end-point of a line to a
second end-point. The vertical line is easily calculated by
subtracting 20 from the original Y coordinate. This gives:

LINE( 1 28,96)-( 1 28,76),PSET

(128J6)

(?,?)

(t2a,96)

Figure 2
First Line

May 1964 the RAINBOW 125

The second line is harder. Some geometry or trigonome-
try must be used. If you look at Figure 3, you can see that a
30-60 degree right triangle can be formed to aid the
calculatidns.

line performs the same function as lines 40, 50 and 60 in the
BASIC program. There is no need to calculate where the end
points of the sides lie in Color LOGO since the lines are drawn
by relative movements shown in Figure 4.

The side opposite the 30 degree angle (the change in Y
coordinate) is equal to one-half the hypotenuse (one-half of
20 = 10). Therefore, the Y coordinate must change by 10
units. The side opposite the 60 degree angle (the change in X
coordinate) is equal to three times the change in the Y
coordinate. This equals approximately 1.732 times 10, or
approximately 17.32. Therefore, you must add 10 to the Y
coordinate and 17 to the X coordinate of the point forming
the end of the first line:

56+ 10 for Y and 128+ 17 for X

The BASIC statement is:

LINE-(145,86),PSET

The final line goes back to the original point ( 1 28,96) by the
BASIC Statement:

LINE-(I28,96),PSET

You can see that drawing the triangle with BASIC is quite a
mathematical chore because the end points of the lines must
be specifically defined. Color logo avoids this point-to-
point construction by using its relative commands FOR-
WARD 20 and RIGHT 120, repeated three times. These
commands can beabbreviated FD20and RT 120. Let's now
take a look at comparable programs in Color LOGO and

BASIC. i

The LOGO procedure must have a name (ours is TRIAN-
GLE). The LOGO statements COLORSET 1 and CLEAR
perform similar functions to the basic statements PMODE
i; PCLS; and SCREEN I,L The REPEAT statement of
Color l6go performs a similar function as a FOR . . .

Now let's move on to a regular polygon with more sides.
Take a regular pentagon (five equal sides). Once again,
BASIC requires some detailed calculations. Since there are
five sides, the exterior angles of the pentagon are found by
dividing 360 by five. This equals 72 degrees. The interior
angles of the regular pentagon are 180-72 or 108 degrees.

Regular Pentagon

Now suppose that you want to draw a regular polygon
with 12 sides. Take a look at this:

1 leave the basic program to you.
Remember, there arc twelve sides
— lots of points.

1 won't go into the calculations necessary to find the end
points of the sides for the BASIC prl^gram. I'll leave that to
you. You can use some of the trigonOnt^try shown in earlier
Using Graphics articles. However, letfs take a look at the
comparison of Color LOGO and BASIC programs.

80 LINE -(I28,96),PSET
90 GOTO 90
100 ESID

Notice that the Color LOGO program for PENTAGON is
the same size as the TRIANGLE program, but the BASIC
program has grown.

Notice that the change in the Color LOGO procedures
merely reflect a change in the number of sides:

REPEAT N{FD 20 RT M)

t t
N = number of sides M = 360 number of sides

This means that you can very easily write one general proce-
dure that will draw a regular polygon of any desired number
of sides. This will be demonstrated in the next issue.

Many people call Color LOGO a children's programming
language. 1 would rather think of it in other ways. It could be
considered a non-mathematician's programming language
as you have seen from the examples in this article. It could
also be thought of as a beginner's language since it is so
straightforward and easy to use. I like to think of it as a
fun-language because I have fun whenever I use it.

♦ Color LOGO is available at your Radio Shack stores in
either cartridge or diskette formats.

COLOR DISK TRIVIA

WITH DEVELOPMENT SYSTEM FOR EDUCATIONAL USE

Here it is! The first new program offered by the author of
the famed VIKINGI in nearly two years, and worth the wait.

Color Disk TrMa

is simply a very good, and very fun to play game. It has
everything going for it: The challenge of trivia, ease of use,
a good social game encouraging conversation, and you
may even learn something! The development system
(included) even lets you easily create your own custom
question disks.

The play of the game is easy to understand, because the
computer does all the work for you. It even looks up and
presents the proper question!

On each question disk there are five categories, and there
are an amazing 1 100 questions on each disk. No, that's
not a misprint, we said 1 1 00 questions per question disk!
Yes, that is a pretty full disk. Because the questions are
stored on the disk, instead of In memory, you can play
COLOR DISK TRIVIA on any size Color Computer system
with one disk drive — 1 6K, 32K, or 64K.
There are already five question disks available, and you
get the GENERAL disk when you purchase the game.
That* s correct, there are already FIVE question disks with a
total of 5500 questions available for shipment RIGHT
NOW, with more on the way shortly.
All question disks have five categories and 1100 ques-
tions. The disks available now are:
GENERAL: (Included with the game) The categories for
this disk are history, the written word, movies & television,
science & the world, and sports.

ENTERTAINMENT: These categories are movies, the
stage, television, music, and literature.
BIBLE: 1 1 00 questions in five categories on the Old and
New Testaments.

SPORTS: This disk will challenge even the very know-
ledgeable sports fan. All major sports (and some minor
ones) are represented.

CHILDREN: No, this isn't questions ABOUT children, it's
questions FOR children. 1 100 fun questions just for the
younger set.

The game of COLOR DISK TRIVIA can be played by from
1 to 4 people (orteams), and you set the length of the game
at the start when you decide how many questions must be
answered in each category to win. The computer chooses
the categories randomly, though sometimes it will let you
choose the category for yourself (or let your opponents
choose for you). Because of this category selection by the
computer, a single category can often hold you up while
one of your opponents slips by to win. The outcome is
always in doubt, and no player is ever eliminated.
Trivia lovers will enjoy the fact that you can play without
other people if you desire, because the computer will
provide plenty of challenge. We want to emphasize that
this is, first and foremost, a fun game.

Your Personal check is welcome - no delay. Include
$1.50 shipping for each program ordered. (Shipping free
on $50.00 or larger orders). AZ residents add 7% sales
tax Orders shipped within two days.

The Development System

Naturally, in order for our programmers to type in thou-
sands of questions easily and accurately, a good develop-
ment program to create the question disks had to be
written, and we include this program with the game at no
additional charge!

The prog ram is all menu-driven and very user-friendly. That
means that no knowledge of programming is needed to
use it. If you can turn on your computer and type, you're all
set! Now sit back and imagine the educational possibilities.
Yes, our question disks have 1100 questions, but the
game program will handle question disks having any
number of questions from 5 up to a full disk of 1 1 00, so a
teacher can type in 50 or 1 00 questions and answers (the
questions are multiple choice), and then the students can
ptay the "game" and have a great time, while accidently
picking up the lesson. Let the natural spirit of competition
fuel the learning proces&

The development program is very easy to use, and gives
you options to add questions, change or delete a question,
and print the questions and answers on the screen (or a
printer, if you have one). You can develop a question disk
and easily add questions to it any time you wish.
This program finally gives parents and teachers the op-
portunity to easily create a custom learning program for
any level student, and if we keep it a secret, no-one need
know it's more than a game.

TECHNICAL INFORMATION: COLOR DISK TRIVIA is a

mixture of Machine Language and BASIC. It uses Fielded
Direct Access Disk Files. COLOR DISK TRIVIA requires

Color labels from your CGP-115

Special Delivery

By Thomas Szlucha

Do you want to really impress someone receiving mail
correspondence from you? Try using a custom label
drawn in colors with the CGP-1 15 printer/ plotter.
CGPLABEL is a program designed to draw such a label
allowing the selection of one color for the text and another
for a neat border drawn around the address. Figure 1 shows
an example of such a label addressed to our favorite Color
Computer magazine.

In developing this simple program 1 discovered a couple
of interesting things about the CGP-1 15 printer that are
worth passing on to other users. In the instruction manual,
the "S*' command used to set the text scale in the graphics

The other interesting discovery worth noting is that,
although the documentation states that text mode character
sizes are limited to 40 and 80 cpl, there is a technique that
allows any of the graphics mode character sizes to be availa-
ble in the normal text mode. When the printer is turned on, it
cycles up in the text mode with the character size determined
by the positon of dip switch 2 on the back panel. To change
the character size, simply enter the graphics mode, PRINTS-
2XHR$(18) and [ENTER] the scale desired, PRINTS-
2/'Sx" Then switch back to the text mode, PRINn-2,
CHR$(17). The printer will stay at that character size until
switched off or a new size is selected.

mode allows values of zero through 63 to produce character
sizes between 80 and one characters per line (cpl). This could
obviously be interpreted as providing 64 unique character
sizes. Unfortunately, this is not true. There are only 16
different character sizes because the formula to calculate
cpl, shown beloWi is rounded off by the computer to the next
lowest whole number.

cpl = 80/ l+S where S is the scale parameter

Table 1 shows the relationship between values of S and the
resulting characters per line.

(Thomas Szlucha, a frequent contributor to the Rain-
bow, enjoys free-lance writing. Home computing is a
hobby enjoyed by his whole family,)

CGPLABEL is designed to work with the MC-iO, as well
as the 4K Color Computer. It produces labels that are
center-justified, using the largest character size that will fit
the width of the paper. The label will fit in the sending
address area of a business envelope and is large enough for
packages. Being written for MC-IO and Color BASIC, com-
mas are not allowed in the address. If you have Extended
Color BASIC, change lines 20, 30 and 40 from INPUT to
LINEIN PUT to accept this punctuation. If you would like
the address left instead of center-justified, change variables
LI, L2, and L3 in lines 190, 210 and 230 to LM.

Unfortunately, real label stock is not available for the
CGP-1 15. 1 find a glue stick handy for attaching the finished
labels. The program provides dashed lines above and below
the label to aid in trimming.

A colorful program to make your work look as,..

Pretty As A Picture
With CGP-115

By Thomas Szlucha

I would like to share this program with the many CoCo
artists who like to have a permanent copy of their work.
The program entitled GPDUMP is designed to take a
picture drawn on the screen and reproduce it with the CGP-
1 15 printer/ plotter. If you have not seen one of these print-
ers — or have ignored it thinking because of its small size
that it must be a toy — it is really worth examining.
Although it is small, it packs a lot of capability in a minia-
ture scale, but this is not meant to be a Radio Shack adver-
tisement, so on with the discussion of a very practical appli-
cation for this printer.

The concept employed to create a screen dump is quite
simple. The "screen" is scanned, interrogating each pixel
encountered with Extended Basic's P POINT command,
Dependingon whether the pixel is "on" or "off," the instruc-
tion to write to the equivalent area on the plotter paper with
either a space or a line is given. In actual practice, to speed
up the plotting routine, the length of a continuous string of
on oroff pixels are accumulated in variables A and B,and a
string variable PS$ is built containing the appropriate print
commands needed to recreate the scanned line. After the
complete line is scanned on the screen, the command to
draw the line is sent to the plotter. Speed was an important
consideration in developing this program. Several tech-
niques were employed to achieve maximum efficiency.
These include placing the main scanning routine in a tight
loop at the front of the program, and utilizing the famed
CPU speed-up poke. Plotting a screen dump is still time
consuming, influenced by the inherent speed of the printer
and the large number of lines needed to recreate the screen,
as well as the use of basic instead of machine language. A

(Thomas Szlucha, a technical specialist / project man-
ager of Xerox Corporation, is a frequent contributor
to the Rainbow. He enjoys writing software as a
hobby,)

machine language version of this program is under devel-
opment.

The screen dump was designed to produce either a 1 or2x
scale enlargement with the 2x mode drawing a line twice as
long for each pixel encountered on the screen. To take
maximum advantage of the width of the printer, the scan-
ning takes place vertically on the screen and is transposed
horizontally to the plotter. This allows 384 (2 x 192) of the
480 possible plotting positions to be utilized in the 2x mode.
GPD(/A/P works in either PMODE3 or 4, You are allowed
to choose the color to be "sensed" by the PPOINT com-
mand, as well as the color to draw with. In addition, you can
overlay several colors (one per pass) but be prepared to
spend some time at it — a single color pass in the fx mode
takes about 15 minutes. Since the program takes considera-
ble time to complete a pass, a "finished" buzzer has been <
incorporated so that the computer can be left unattended.
Perhaps you can spend the time catching up on your Rain-
bow reading. If you are like me. Rainbow has gotten so large i
it is hard to find time to finish one issue before the next
arrives.

In order to test the plotting routine, a simple argyle-like
mosaic is d ra wn as a "test pattern." Selecting the test pattern
option draws the picture to the screen, then dumps it to the i
plotter. There are two different ways to plot a picture of your f
own choice. You can append a picture drawing routine of
your own, taking the place of the "test pattern" which starts |
on line 500 in the program. An alternate technique requires I
that you draw your own picture on the screen and in
memory using another program or graphics drawing utility.
Then load in GPDUMP and set the PMODEand SCREEN \
parameters in lines 120 and 300 to the appropriate value. i

If your CoCo can't handle the higher speed from the I
speed-up poke, delete lines 13, 240 and 250. If you do use the
speed-up poke, exercise some caution — remember that if
you exit the program with the [BREAK] key you should hit

HARDWARE Voice Synthesizer

COLORWARE..
only.., $59.95

THINKING OF BUYING A
COCO VOICE SYNTHESIZER?

READ THIS..,.

Making your computer talk couldn't be any easier!
'Real Talker' is a full featured, ready to use, HARDWARE
voice synthesizer systenn in a cartridge pak. It uses the
Votrax SC-01 phoneme synthesizer chip to produce a
clear, crisp voice.

FREE TEXT-TO-SPEECH

Included free with 'Real Talker' is Colorware's
remarkable Text-to-Speech program. This is a truly
powerful machine language utility. What it does is
automatically convert plain English to speech. And it has
an unlimited vocabulary! For example, use it in the direct
mode: Type in a sentence or a paragraph, even mix in
numbers, dollar signs, etc, then press enter. The text is
spoken. At the same time a phoneme string is generated
which can be saved to cassette or disk, modified or used
in a Basic program.

We originally planned to sell this major piece of
programming for about $40.00 but decided it was so
useful that no 'Real Talker' user should be without it.
Besides, it really shows off the capability of 'Real Talker'.

Also included with 'Real Talker' is our unique Phoneme
Editor program. It allows you to explore and create
artificial speech at the phoneme level. Phenomes are the
fundimental sounds or building blocks of word
pronunciation. There are 64 different phenomes, as well
as 4 inflection levels at your disposal. Creating and
modifyirrg speech at the phenome level is both fascinating
and educational. The Phenome Editor may also be used to
customize the pronunciation of speech produced by the
Text-to-Speech program.

You don't have to use any of our utility programs
though. If you write your own Basic Programs, you will
find the pocket sized Votrax Dictionary (included free) is
all you need to make your own Basic programs talk. This
dictionary gives you quick access to the phenome
sequences used to create approximately 1400 of the most
used words in the English language.

How about compatibility? 'Real Talker' is compatible
with any 16K, 32K, 64K, Extended or non-extended Color
Computer. It works with any cassette or disk based
system, with or without the Radio Shack Multi-slot
expander. No other synthesizer under $100 can make this
claim. Most other CoCo voice synthesizers require an
expensive Multi-slot expander in order to work with the
disk system. 'Real Talker' requires only an inexpensive Y-
adapter. This is an important consideration if you plan on
adding a disk or have one already.

'Real Talker' comes completely assembled, tested and
ready to use. It is powered by the CoCo and talks through
yourT.V. speaker so there is nothing else to add. Price
includes Text-to-Speech and other programs on cassette
(may be transferred to disk), User Manual and Votrax
Dictionary. ONLY , $59.95

'Y-BRANCHING CABLE' For disk systems. This 40-pin, 3
connector cable allows 'Real Talker' to be used with any
disk system $29.95

YOU DECIDE....

Order yours today on our Toil-Free Order Line. If you are
not delighted with your 'Real Talker' system, simply

computer is instructed to set the printer output to 300 Baud.
In actuality, this is 600 Baud in the speed-up mode. This is a

After keying in the program, be sure that fresh pens are
installed on the CGP-1 15. Dumps with this program will
stress them. Try the test pattern or load your favorite gra-

the time spent. There is something exciting about a "hard"

Rainbow Contributing Editor

A Database
Manager
For Dragons

This column is written for people who play fantasy
role playing games like Dungeons & Dragons, Rune-
quest, Tunnels & Trolls, apd Superheroes. In this
column we explore ways for players of these extremely
complex games to use their computers to aid them in their
enjoyment of the gartie. The programs we present here are
not games, but rather game aids, and the games we consider
are not computer games, although computers have many
uses to the players and referees.

Previously, we have looked at ways to use the computer to
keep some of the records which are necessary in these games,
and this month we will look at that concept again, taking a
more "dii-ect" approach.

This column is aimed at users of disk systems, but some of
the programrping methods used are applicable regardless of
the size of your system. The program below will run on any
size disk system, because it uses direct access disk files.

In a sequential access filing system, the computer must
start at the beginning of the file and look until it finds the
desired item. Also, it is not easy to change one item in this
type of file. Direct access is called that because you can go
directly to any point in the file, but before we get into that,
let's look at a few terms we will be using.

The three basic terms of any record-keeping system on the
computer are file, record, and field. 1 will be using all three
words repeatedly, so let's get the definitions agreed upon
now. The analogy is usually made to a standard record
system kept in a filing cabinet. The entire cabinet, or the
whole group of file folders taken as a whole, is called the file.
Each individual file fdlder is called a record, and each piece
of itiformation inside that folder is called a field.

(Bill Nolan is a principal in Prickly-Pear Software,
DMs a weekly game of Dungeons & Dragons, and
teaches Programming In BASIC at a local college.)

In a mailing list, then, the name, address, city, state, ZIP
code, and phone number are each fields, while all of the
information about one person is a record, and the entire
mailing list is called a file. Wh^t we are going to learn to do is
create a direct access file to store information about fantasy
role playing characters.

With any filing system, whether or not it is on a computer,
you must decide what kind of information you will need to
store, how much of it there is, and how it is to be accessed.
Only when these things are decided can the organization of
the filing system proceed. By the way, a bunch of informa-
tion like this is called a "database" by computer people, and
a program like the one we are about to write is called a
Database Manager.

As anyone who has played fantasy games will testify, the
information on a single character will often occupy many
pagesi For the purpose of this program we want to keep
thingis simple, so we are going to consider only the really
basic information about a character. The items 1 have
chosen to use are Name, Race, Sex, Class or Classes,
Strength, Intelligence, Wisdom, Dexterity, Constitution,
Charisma, Hit Points, Armor Class, and Level. Each of
these items of information is called a field, and all of them
together are referred to as a record.

When you are dealing with direct access disk files it is
necessary for each record to be the same length as every
other record, because the computer will be pulling them out
of and inserting them into the middle of the file. Because of
this, you must first decide on the length of the record, and to
do this, you must decide on the length of each individual
field inside the record.

Deciding how long each field will be is simply a matter of
deciding how many characters you expect the longest item
of that type will have, including spaces between words. For
the purpose of this program I decided to allow 20 characters
for the name; 10 for the race; one for the sex; 20 for the class

142 the RAINBOW May 1984

(allowing for multi-classed); five for strength (allowing for
exceptional strength); two each for intelligence, wisdom,
dexterity, constitution, and charisma; three each for hit
points and armor class; and five for level. If you add all these
up, you will find that they total 77, and this is the number of
characters in each record. All of the records created by this
program will be 77 characters long, and if any field is too
short, it will be filled out with blank spaces to make it the
right length. As you will see, this is done easily by the
computer, using a special command just for the purpose.

Before we get into the actual program, we need to decide
where we are going to do what. To make that a little more
clear, any program breaks down into sections, and it's a
good idea to decide ahead of time what sections you will
need and what line numbers you want to allocate for each
section. Then, instead of working on the entire program at
once, you can work on each section, and you will find the
task to be much easier. This is called block programming,
and in addition to making the program easier to write, it also
makes it easier to change later if you need to do that.

In this program I decided that 1 would use lines from 10 to
999 to do any initial setup needed. You will notice that I
actually needed only a few of those lines, but it was nice to
know the others were there if I had to use them. Besides, you
can use line numbers as high as into the 60,000s, so why cram
everything together?

1 used the lines from 1000 to 1 100 to print out the menu
and get the user's response. There are four items on the menu
— print characters, add characters, change characters, and
end the program — so 1 knew 1 would need four additional
sections, or blocks, to handle the four choices. 1 put the print
characters section in line 1500, the add characters section in
line 4000, the change characters section in 6000, and the end
program section at the end of the program, line 12000. The
line numbers from 10000 to 1 1000 1 reserved for subroutines
that would be called from other places in the program. Nqw
that we h^ve a map of what we are going to do, we can
proceed to examine the program.

In lines 10 to 25, 1 DIMension the two arrays 1 will use,
print the title screen, and read the names of the fields into
one of the arrays, NFS. The NF stands for Name of Fields,
and whenever possible you should use variable names that
mean something to you. The array D$ will be used to hold
the DA TA about each character. The reason for the periods
in the DATA is to make each field name the same length, so
the printout will line up.

Line 1000 simply prints the menu, 1005 gets the user's
choice and checks it to make sure it is a valid entry, and 1010
branches to the four main sections of the program. Line
1 2000 is easy, as it clears the screen, does an unload (which
closes all open files), and ENDs the program.

I will look at the routine located at 4000 first, as this is the
add a character section, and you can't do anything else until
you have put a few characters on the disk. Line 4000 is a
GOSVBXo 10200, where we remind the user that there must
be a DATA disk in the drive (the subroutine at 1 1000), and
then open our file. Line 10210 tells the computer to open
buffer 1 for direct access to a disk file name "CHAR/ DAT,"
with a record length of 77 characters. Line 10220 tells the
computer how long each field will be, and which variable
name will refer to which field. Line 10230 RETURNS to
4020, where the screen is cleared. Line 4030 finds out how
many characters are presently in the file, and adds one to
that number, so that we will create the next record number.
Line 4040 tells the user which record number he is inputting,
and line 4050 gets 13 iNPUTs^ one for each field, storing this

information in the array D$. Line 4060 prints the informa-
tion out so the user can cheek it, and if they approve, line
4 1 50 d oes a GOSUB to 1 0 1 00. This subroutine is a group of
L5'£T statements. These not only transfer the information
in the array D$ to the variables specified by the FIELD

"Any program breaks down into sec-
tions, and it 's a good idea to decide
ahead of time what sections you will
need and what line numbers you want
to allocate for each section . . . [50,]
work on each section, and you will find
the task to be much easier. This is
called block programming,

command, they also make everything the right length. If it is
too short, it will have spaces added to the end of it, and if it is
too long, it will be chopped off to fit. This command also
transfers the information into buffer I, and then the pro-
gram RETURNS to 4 1 60, where the contents of buffer 1 are
put on the disk as record #N . Lines 4 1 79 and 4 1 80 find out if
the user has more characters to add. If they do, it returns
them to 4020, and if not, it sends them back to 1000, which is
the menu.

Once you have a few records in the file, you may want to
print them out. The program allows you to print on the
screen or printer, and to print all records or to search for and
print only those records that meet certain search criteria.
You can search on any field in the record. The printout
routine is located starting at line 1500.

The first things the program does in this section is to set
SF (the search flag) to zero, and ask the user whether they
want to print all records or only specific records. If the
person chooses to print all records, the variable SF stays at
zero, and in line 1520 the program jumps to line 2000,
skipping the search setup lines. If the person wants a search,
then the program continues on line 1530 by setting the
variable SF to one, indicating that a search is in progress,
and printing a numbered list of the field names on the screen,
so the user can choose which field is to be searched . Once the
search field is entered, it is checked to be sure it is an integer
from one to 13, and then the search target is prompted for.
The target is the word, number, or phrase that the computer
will try to match, and it must be character for character the
same as what you typed in when you were adding tHe charac-
ter. Once the target is obtained, the program goes to 2000,
where the actual printout routine is located.

At line 2000, the first thing asked is whether the user wants
the output printed on the screen or printer. Most of you are
aware that the printer is device #-2, and that to print to it
you use the form PRINT ^-2/'message*\ Less known is the
fact that the screen is device #0, and that you can print to it
with the command PRINTS,** message ". Since you can use
a variable instead of the 0 and-2, it is only necessary to
assign a variable as the device number, and then set its value
to be either 0 or -2. 1 use the variable DN for this purpose.

May 1984 the RAINBOW 143

If the person chooses to print on the printer they are given
a choice of printing continuously, or of having to press a key
after each record is printed. If you have a tractor feed
printer, you will want to choose continuous, but if you have
a single sheet printer, you will want to choose to have the
printing pause after each record so you can change the
paper.

The actual printing routine starts in 2050, with the
G OS UB to 10200 to open the buffer to the file. After finding
out how many records there are in the file in line 2070, the
program establishes a FOR . . . NEXT loop to look at each
record in turn. Line 2090 GETs record #X, and then the
program GOSUBs to 10000, where the F/ELDe^/ variables
are stored in an array. This not only makes them easier to
access, it is also necessary because of something which is
never explained in the disk manual. You must do something
with the FIELDed variables, which you GET before you
close the file, because if you don't, they will go away when
the file buffer is closed. By transferring them into an array,
we make them less ephemeral.

Line 2097 first checks the value of SF to see if a search is in
progress, and if it is, then the remainder of the line checks for
a match between the target and the field previously indicated
by the user, if a search is in progress, but no match is found,
the line directs the program to jump past the print line, so
only those recdrds fitting the search are printed. The reason
for the LEFTS command in line 2097 is to eliminate the
spaces which may have been added to the field by the LSET
command. If you would prefer that the program find partial
matches within the field, instead of requiring an exact letter
by letter match, line 2097 can be changed to read:

2097 IF SF=1 THEN IF INSTR(1,DS(X),TG$)<1
THEN 2120

The disadvantage of this is that you can get some odd
matches. For instance, if you are searching for an eight in
intelligence, it will also find 18, because it has an eight in it.

Line 2100 prints out the record, including the record
number, which you will tieed to have in order to change the
record, and when all of the records have been examined, the
file is closed in line 2140 and the program returns to the
menu at 1000.

The last section remaining is the change a character sec-
tion at line 6000. First, the file buffer is opened, and the
fields are specified. Then, in 6030, the user is asked which
record number they want to change, and in 6045 this record
is obtained from the disk and the program GOSUBs to
10000 to transfer the information into the array D$. In 6050
a numbered list of all the field names and their current
contents is printed on the screen, and the user is asked which
field they want to change. Then in 6060, the new information
for the field specified is input, and in 6070 the list of field
names and contents is printed on the screen again, so the
user can check it. If the change was not made correctly, or if
there are more fields to change, the user can indicate "not
correct" in lines 6140 and 6150, and they will get a chance to
make additional changes.

Once the user indicates that all is well, the program in line
6\60 GOSUBsto lOlOO, where the L5£rcommands get the
buffer set, and then in 6 1 70 the new record is put back into
its proper place in the disk file. In lines 6180 and 6190 you
can specify more changes, and you will be returned to 6020
to pick a record number. If you say you have no more
changes, the file buffer will be closed in line 6200, and line
6210 returns you to the menu.

That's about it for the line by line commentary on the
program. If you do any programming at all, you will be able
to fairly easily modify this filing system to be a pretty good
mailing list. I did it in less than one hour. Also, if you are
curious, you will be able to store about 2000 character
records on a disk before it will be full. I hope you find this
very basic Database Manager to be useful, and 1 hope it
inspires some of you to expand it into a really complete
character filing system, if you do that, be sure to send me a
copy so I can see it. So, until next time, keep your swords
sharp and your maces heavy, or do what I do — practice the
100-yard dash. Remember my immortal battle cry, "Run
Away! Run Away!"

But true! There is a disk
drive In your Color Compu-
ter . and it is faster and
more efficient than any
"hardware" drive you can
buy, for any price. This new
"disk drive" is called VDOS—
for Virtual Disk Operating
System— and it will absolutely
revolutionize the way you
operate your CoCo.

VDOS lets you use the
"extra" memory inside your
CoCo as a virtual disk, with
programs (any programs)
stored out of the way. You
can "save" and "load" pro-
grams from your In-memory

disk Into working memory,
and then run them. When
you're done, you can simply
access your in-memory disk
again . . . and save or load
another, and another.

And VDOS is fast.
Because you are using
memory rather than a
mechanical device (like a
disk drive or cassette
player), programs load
Instantly. Yes, VDOS is fas-
ter than a disk!

VDOS works with ali
Color Computers— from
16K non-extended to 64K
extended. Obviously, the

more memory you have, the
greater number (and
length) of programs you
can store. For a 64K sys-
tem, VDOS also uses the
"unused" part of memory,
providing up to 50,000
bytes of storage! Now,
that's some disk!

We call It VDOS because
in the future there will be
utilities for your VDOS
UNDISK that wiii give even
greater capabjiities— such
as a full one-pass memory
dump to cassette. Other
utilities are planned, too.

We believe VDOS Is the

greatest advancement for
CoCo since the introduc-
tion of the disk drive itself.
And, at less than $100, it is
so inexpensive you can*t
afford to be without it. If
you have the "cassette
blues." VDOS Is the answer!

Finally, VDOS is simple to
operate. It is entirely self-
prompting and comes with
a complete manual. But you
almost don't even need the
instructions— it requires
absolutely no technical
expertise.

VDOS. The answer to
your prayers.

UTILITY

Synchronous Output
Can Be Useful

By James Provost

Here is a very useful program
for Adventures and other text
programs where a hard copy of
what is on the screen is needed. SYNC is
designed to produce a syncronous out-
put to both screen and printer.

The user should make sure that
his/her printer is on-line before RUN-
ning the program or else the computer
will "hang. "The syncronous output will
be in effect until the computer is powered
down.

For users with 64K — while in the
64K mode, POKE &HA1A5,&H12 to
achieve a solid cursor. This places a
NOP into the address which formerly
held the instruction for the cursor to
change to another color.

RADIO SHACK has released several
new products this month. Among the
best is the C-Compiler, a versatile and
efficient programming language for the
64K Color Computer and the OS-9 disk
operating system. The C-Compiler can
easily handle tasks that previously would
have required complex assembly lan-
guage programming. Programs written
in C are more portable between radically
different computer systems than other
standardized languages such as BASIC
COBOL, and PASCAL, and it works par-
ticularly well with the 64K CoCo because
the 6809 microprocessor was designed
specifically to run high-level languages.
(For more information, see Dale Puck-
ett's "KISSable OS-9" column on Page
297.) The C-Compiler is available for
$99.95 at Radio Shack stores nation-
wide.

Also introduced for the 1 6K or greater
CoCo is Personal Finance II, a program
that aids the user in setting up a budget,
tracking bank accounts, and evaluating
expenditures. It can keep track of nine
bank accounts and 25 budget catego-
ries, store 1,818 checks on tape, and is
available on cassette for $34.95.

For the MC-IO, Radio Shack has
introduced Math Design and Lost
World Pinball. The Math Design pack-
age contains two packages: MiniCalc,
which functions as a hand-held calcula-
tor, and Spirals, a fun geometric exer-
cise that makes it possible to design and
plot a large variety of polygonal spirals
in four colors. Both are available on
cassette for $9.95 each at all participat-
ing Radio Shack stores.

A $10,000 SCHOLARSHIP has been
announced by Ray Jacobs, president of
Software City. It will be awarded to the
student who produces the most market-
able computer program. In addition,
four $1,000 scholarships are offered to
the runners-up.

Applicants must have been graduated
from high school after Jan. 1, 1984, and
entries must be submitted by Dec, 31,
1984.

Categories in which entries will be
judged are: Business Applications, Ed-
ucation, Home Applications, Recrea-
tion and Systems Software.

Requests for complete information
and scholarship applications should be
directed to: Software City Corporate
Headquarters, 1415 Queen Anne Road,
Teaneck, NJ 07666, Attention: Schol-
arship Director.

THE PRICE OF SECURITY, ADM

Concepts has announced the introduc-
tion of a new low-cost data system
security link called the COM M LOCK
Model-96A. It has been designed to be
compatible with all standard asynchron-
ous data communication systems.

COM M LOCK'S design provides for
a virtual secured communication link to
corporate, military and private compu-
ter data banks. The COM M LOCK link
must, however, be installed between the
computer and modem at both the trans-
mission and reception sites.

Using this dual encryption method,
though, is far more secure than the more
common single encryption. Also, COMM-
LOCK is programmable by the user for
creation of up to 1,024 unique encryp-
tion codes. It is programmable for data
rates (300 to 9600 bits per second), word
length (5 to 8 bits), and parity and
number of stop bits — which makes it
compatible with all asynchronous com-
munications.

At $600 in single-piece quantities,
COMMLOCK provides a low cost sol-
ution to the data security needs of large
corporations and the military, but for
personal computer networks, putting
your trust in the gods for security is, let's
face it, a heck-of-a-lot cheaper.

COCO CELEBRITY Bob Rosen says
that he liked California so well when he
attended the RAlNBOWfest in Long
Beach, he has decided to pack his bags
and go west. And that means that Spec-
trum Projects will be expanding. In
April, Bob will be opening the West
Coast Division of Spectrum Projects
and, in conjunction with that, he will be
warming up four more of his popular
Rainbow Connection bulletin board
systems. The new West Coast address is
#9866, 4285 Payne Ave., San Jose, CA
95117.

Not to worry. Easterners — Bob's

brother, Paul, will continue to operate

their East Coast offices in Woodhaven,

KEEPIN' AN EYE ON COCO. M icron
Technology, Inc., a western memory
chip manufacturer, has introduced two
new products that give the gift of sight
to your favorite computer. Both the
MicrortEye Bullet and the MicronEye
Camera make use of a revolutionary
image-sensing chip — the 1S32 Optic-
RAM. This chip is composed of 65,536
individual pixels and is capable of send-
ing remarkably high resolution images
to the screen of most computers.

Uses for the MicronEye are virtually
unlimited and include: character recog-
nition, signature verification, graphics
input, automated monitoring, surveil-
lance and motion detection, barcode
reading, robot vision, and the list goes
on. What does seem somewhat limited,
however, are the MicronEye 's capabili-
ties with the CoCo in comparison to
other computers. These seem to include
the inability to store and recall pictures
from disk and the inability to dump to a
printer — two pretty important features.

The entire package for the Bullet,
including camera, lens, tripod, interface
card and software, is priced at $295 — it
might have cost $30,000 two years ago.

compatible with all the other programs
in the VIP Library and features memory
sense-bank switching, true lowercase,
16 video display windows, 15-digit pre-
cision, and other features of the VIP
Library. We understand that Softlaw
has been shipping VIP Calc for several
weeks now.

VIP Calc comes packaged in a hand-
some, 5V2 X %V2 inch, three-ring binder;
somewhat smaller than the old Super
"Color" binders, but just as attractive
and functional. The package contains
both disk and cassette versions of the
program and 178 pages of documenta-
tion. Both the disk and tape contain
separate 32K and 64 K versions of the
program; the 32K version does not have
Hi-Res displays or the sort and edit
functions featured on the 64K version.

V!P Calc is available for $59.95 from
Softlaw, 9072 Lyndale Avenue So., Min-
neapolis, MN 55420.

J.. ..\^

Here is a garage sale program that will do it all for
you. No more scribbling on a scratch pad, trying to
keep track of everyone's money. Just CLOAD Gar-
sale and you have a cash register that will ask for: Sellers,
Price Of Item, and Quantity, It will give you the Total
Amount Of Sale, then ask for the Amount Tendered and tell
you the Amount Of Change.

As an added attraction you can put any message you want
on the screen. Do you have a special item you want to
advertise? Well, just put it on the screen where everyone can
see it. This is sure to be an eye-catcher.

You can change the message any time. All instructions are
documented on the screen except while the message is there.
You must hit [CLEAR] to return to the sellers list.

At the end of the day just ask and you will receive the total
amount sold for the day and the amount each person should
receive.

If you don't have enough memory for the entire program
you can delete the message portion as follows:

Delete lines 5-775

Delete lines 885-895

Delete lines 1535-1555

Change line 1575 to — "GOTO 935"

1200 name capacity*. All reports are printable with most 80
column printers.

FINANCE 4 lets you determine the "what if's" of your financial
future. With this easy to learn spreadsheet you'll spend
more time making decisions and less time crunching
numbers.

¥xi Can Bet On

MASTER

By Leonard Hyre

Some things just go together: Love and marriage, milk
and cookies, apple pie and mom, and of course, horse
racing and CoCo! Horse racing and CoCo? Well,
maybe you think this is a bit of an exaggeration. 1 will admit
though, that from the day 1 brought home my CoCo, the
pair were on my mind. 1 had to believe that my unrelenting
love of racing and the unwavering logic of the CoCo were
just intended to get together. The results were Harness Han-
dicapper and Thoroughbred Handicapper. But the CoCo
has other possibilities also. Thus Wager Master came about.

Competent handicapping is only one-half of the formula
for successful wagering at the races. It has been my expe-
tired from really trying to win, this can be difficult. Several
of the features of Wager Master are designed to assist in
setting up prerace selections of these types of bets, using the
probable winner as the key ingredient.

(Leonard Hyre, author of Thoroughbred Handi-
capper and Harness Handicapper, both marketed
through Federal Hill Software, is also the author of
several programs which have appeared previously in
the Rainbow. As well as being a CoCo enthusiast, Mr,
Hyre is a claims representative for the Social Security
Administration.)

Upon running Wager Master, the user is prompted with a
menu from which one of eight options can be selected. Seven
of the eight offer printer options and six require user input.
To maximize user audience, I have kept Wager Master to
rience to know several incredibly knowledgeable handi-
cappers who never seem to make a reasonable profit. The
reason — money management! A little planning, especially
before you even arrive at the track, Is a big start on financial
success to go with the handicapping.

Wager Master is a tool to aid in that money management
need. By carefully weighing the probable odds on your
selections and experimenting with them, you can better
determine the chances of a reasonable return on an invest-
ment. It also satisfies that "tinkering" nature of racing fans
who like to doodle around with odds and the like.

While 1 personally prefer win or win/place wagering, 1
will admit to that occasional weakness of a double, exacta or
triple bet. Though not the soundest of ideas in even the best
of conditions, the urge to drop a bit on these "exotic" bets is
virtually impossible to resist. 1 believe the weakness of this
type of wager is that the handicapper must pick not only the
winner, but also is betting on who will lose and by how
much! Since second- and third-place finishers are sometimes
horses who got there simply by passing horses that were

within 1 6K parameters and all print routines are done using
TA Band PRINTUSING commands so as to be compatible
with all printers. Also, the printouts are limited to a 40-
column printer width. For those with no printer, all infor-
mation is displayed on the screen first.

Lines 190-320:

Standard Payoffs (option 1) requires no user input and is
simply a table of payoffs at various odds. The win table is, of
course, easy to determine. The figures used for place and
show columns are estimates based on average payoffs for the
odds shown and should not be considered as necessarily
accurate. The betting public can do strange things. The table
may be printed out for handy reference at the track.

A Return Per Specific Wager (option 2) section is pre-
sented for the fun of the "what if" in uSi Just input antici-
pated odds, the amounts to bet on win, place and show, and
instantly be presented with the fortune you anticipate will
come rolling in. Print it out if you wish.

Lines 610-810:

Option 3 is Wagering Record Keeper, a truly handy way
of keeping your racing records. 1 find this infinitely better
than a huge stack of accumulating Racing Forms and har-
ness programs. With place, date, name and results for the
entire day on a handy sheet, you can quickly see how you
have done, now and in the past, and make adjustments
accordingly to your style.

Lines 820-1050:

Play around with Return Per Specific Odds (option 4),
requiring limited user input and returning the amount a
variety of different size win wagers would return at given
odds. Printer option available here also.

Lines 1060-1540:

Options 5, 6 and 7 offer the most likely combinations to
win an '^exotic'' wager based on your best handicapping
information. All three offer "hedge'* bets as well and can be
routed to the printer.

Lines 1550-1580:

A general statement is offered as an Overview (option 8).
This is to remind would-be users of the fact that the program
does not do the handicapping and that the place and show
charts are strictly estimates!

Wager Master is both serious and fun for the casual or
regular horse racing fan alike. 1 hope you will agree.

Programming structure is kept relatively simple. If you
haven't been making much use of the powerful PRINT
USING command, a review of the program might be useful.
The program is broken down into eight distinct subroutines,
one for each option, accessed by a single ON-x- GOTOWnQ.
DA TA statements are read in as four strings representing
odds, win payoff, place payoff and show payoff. These are
then manipulated as needed by each of the subroutines to
obtain desired results.

If you don't want to type in the program, I will be glad to
send you a copy of tape for $4.50. Just send check to: L.

RAINBOW

By Jerry D. Forsha

e'Nerd is my version of Q-Bert for I6K Extended
Color BASIC. To load Q-Nerd turn the computer off
and on or POKE II3J [ENTER] and press the
[RESET] button. Load Q-Nerd and RUN,
Q-Nerd uses the right joystick for movement. To move
Q-Nerd dov^n to the left, move joystick down and to the left.
Right, up and down directions, also move appropriately
with the joystick.

As Q-Nerd n\o\cs, the blocks change color from green to
blue, but you must change all blocks to the same color
before the colors change. You start with three men. As you
move on the blocks, points are scored. On the first color
each block is worth 10 points and each time you change
colors the points increase by 10. Extra men are given points
of 4,000 for the first one, 8,000 for the next one, 16,000 for
the next one, etc., to a total of five extra men. If you fall off
or the snake and/ or ball catches you then your points will be
updated.

Line Description

Line 0 sets up dims and variables.

Line 1 disables [BREAK] key, (BASIC runs 30 percent
faster).

Lines 2-17 set up game: draw men, blocks, wait to start
game.

(Jerry Forsha is a retail sales auditor and free-lance
computer programmer specializing in business pro-
grams. This is his first computer game.)

Lines 18-25 read joysticks; check each block to see if all arc
set to the same color; put ball on screen; check platforms;
check score for extra men: put snake on screen; go back to
read joysticks.

Lines 26-27 put ball on screen; check to see if ball and man

are in same position.
Lines 28-29 move man down to the left; check to sec if man

falls off of the edge.
Lines 30-31 move man down to the right; check to sec if

man falls off.

Lines 32-33 move man up to the right; check to sec if man
falls off.

Lines 34-35 move man up to the left; check to see if man
falls off.

Lines 36-37 check to sec if platform is there; move man and

platform; move snake (if on board).
Lines 38-39 check to see if right platform is there; move man

and platform; move snake (if on board).
Lines 40-49 check to sec if snake is on board; make the

snake chase the man; if man on platform, kill snake over

the edge: check to see if snake and man are in the same

position.

Lines 50-51 draw man going over the edge; update and
draw the score: check to see if this was the last man.

Line 52 if ball or snake landed on man, draw saying and play
*^rats.''

Lines 53-55 end of game: draw score: set up variables for a
new game.

QUALITY PROGRAMS FOR YOUR COCO & TDP-100

PROGRAMS RMUIRE 16K EXTINDED iASIC FOR TAPE, AND 32K DISK UNLESS OTHERWISE NOHD.

Travelin' Toad

TRAVELIN' TOAD is a fully 32K
arcade quality high resolution
action game. You control the toad
with your four arrow keys, and you
must guide the toad across a multi-
lane super highway, and then help him hop across the
canal from log to log and turtle back to turtle back. The
object is to bring the TRAVELIN' TOAD to safety in his
homQ hole. Along the way you may have the chance to
rescue his friend, Tulip Toad, and you may be threatened
by some nasty reptiles, too. To make it worse, you can only
stay out in the sun for a little while or you die. You'll like this
one, 'cause it's the best game of its type available for your
Color Computer. Of course ifs 100% machine language!
Tape - $24.95; Disk - $20.95

Adventure in Wonderland

Simply the best adventure ever written for the color com-
puter. This adventure puts you in the character of Alice as
you roam through the many puzzles and perils of Wonder-
land. To win you must become a queen on the chess-
board, eliminate the menace of the Snark, and escape
from Wonderland. The program uses a full intelligence
simulator so you can enter commands and questions as
whole sentences, not a stingy word or twoAlso, there are
at least three ways out of every trap. (You may think there
is no way out at all, but there are always three ways!) Some
people have so much fun talking to the various inhabi-
tants of Wonderland that they forget at>out solving the
adventure completely. With a vocabulary of hundreds and
hundreds of words you will never run out of topics of
conversation. If you want to try your hand at the best of
adventures, this is it. 100% ML. Needs 32K of memory.
Tape - $24.95; Disk - $29.95

Colorkit

What can we say about the absolute best state-of-the-art
programmer's utility. This program adds 35 commands to
BASIC that should have been there all along and no short
description will do it justice. Summary — light or dark
screen, keyclick, screen editor, programmable keys, a
super memory tool, variable listing echo to printer, BREAK
disable, convert machine language to DATA, global search,
single step thru program run, double space printouts of
program listings — that's less than half of what it will do. It
takes about 6K of space, and If you have 64K you can put It
up high and lose no BASIC space at all. 100% ML. Fully
relocatable. See the great reviews in Nov. '83 issues of hot
Cocoa and Color Computer magazine. Tape ^ $34.95;
Disk - $39.95

Dealer and author inquiries are always welcome.
Canadian dealers should contact Kelly Software
Distributors, Ltd, P. O. Box 1 1 932, Edmonton, Alberta
T5J-3L1 (403)421-8003

Your personal check is welcome - no delay. Include
$1.50 shipping for each program ordered. (Shipping free
on $50.00 or larger orders). AZ residents add 7% sales
tax. Orders shipped within two days.

Rom Free

Another great utility from the clear leader in Color Com-
puter Utilities! This program will free you from your Rom
packs by easily and automatically moving them to tape or
disk. Unlike other programs of this type, the files created
can be loaded and EXECuted just tike any other program.
No boot loader is needed! Once your Rom packs are in
memory, you can examine and modify them using standard
ML routines. Disk drive owners will particularly want to
take note, as ROM FREE will free you from ever having to
unplug your controller. Information needed to create work-
ing backups of virtually all knqwn Rom packs is included.
Get those Rom packs onto disk or tape. 100% Machine
Language. Requires a 64K color computer, any BASIC,
disk or tape. $24.95

Colorcal

is a very different calendar program.
You enter all the dates that are
Important to you, like birthdays,
anniversaries, or any other event in
your life that falls on the same
day each year, and then you save
the program. It actually
modifies itself as you enter your
events, so they become a
part of the program, and
all the holidays are already
programmed in. Now, anytime you want, you can load the
program, specify any year or month you like, and a correct
calendar for that month or year will be printed on either the
screen or a printer. The calendars it prints make a great
gift, and you won't miss those Important days anymore.
Requires 16K and Extended BASIC. Tape $24.95;
Disk - $29.95

Clone Master

This is the ultimate disk backup utility, and who else but
Prickly-Pear, originators of Omni-Clone, could bring It to
you. If you are tired of waiting for your BACKUP command
to finish, youMI like the speed of CLONE MASTER. This
program checks the computer memory size, and if you
have a 64K machine it will do a backup on a full disk in
at>out 7 minutes — including formatting the destination
disk — with only TM RE E swaps, not the seven you are used
to, and if you are running multiple drives, CLONE MASTER
will handle up to 4 double-sided drives. In addition, al-
though we can't guarantee that CLONE MASTER will back
up any disk, it can handle backups of most non-standard
(protected) disks we have seen — not only on the Color
Computer, but on Model III and IV, IBM PC, Kaypro, and
Osborne. It handles up to 256 tracks, single and double
density ^ even on the same track, CRC errors, and lots
more. It even checks th^ speed of your drives for you! If you
are using a disk drive, you know how disks will crash, so
don't leave your valuat)le software unprotected any longer.
Back it up or lose it! CLONE MASTER will adjust to any
memory size and works with any version of the ROM's —
including the JVC controller. $39.95

This is the sixth installment in a continuing series of short 'Printer Mysteries' which
began in November.

Kentucky is known for beautiful, rolling bluegrass
hills, the Rainbow, fast horses and especially to the
sports-minded, "the most exciting two minutes in
I sports" — The Kentucky Derby. The first Saturday in May
is a long*awaited day filled with celebration and excitement
[so thick you can cut it with a knife ... or a racing ticket.

For those of you who have the Printer Artist program
I from the November Rainbow, here's a printer mystery sym-

bolizing that special day and the beauty of Kentucky. RUN
the program and enter the characters below, line by line. For
example, 2X means strike the '*X'* key two times; Ssp means
hit the space bar five times, etc. Consult the instructions in
the November issue.

If you are interested in sophisticated printer art de-
velopment, a complete "Printer Artist" system is available
from Federal Hill Software, 825 William St., Baltimore,
Md., 21230.

S ARCADE ACTION GAMES

Greetings!

Spring has sprung at last, at least out here in Ypsilanti.
The snail is on the leaf. The worm is on the bud. The corn is
planted. The pigs are enchanted. And Ben, having cast off
his winter fur, prances about in sleek abandon.

Ben and I took a walk down to the pond the day before
yesterday. Ben scampered on ahead, scattering out occa-
sional rabbits and quail, yapping and barking for joy. Upon
reaching the pond, Ben suddenly froze. Slowly he lowered
down on his haunches like a sphinx, narrowed his nose, and
began softly whining as if he had just been kissed by a rabbit
in a dream. In a minute, 1 saw what all the commotion was
about. Do you remember that turtle 1 saw swimming in
circles on the pond last summer? Well, now that very turtle
was swimming around in the pond, followed by seven little
tiny turtles. The turtle had replicated.

Gosh, those little turtles were cute. They werejust exactly
like the mother turtle, only miniature. The mother turtle
turned one way, and they followed right along. The mother
turtle turned another way, and along they followed. First I
considered taking them all home with me to try turtle gra-
phics on paper, just as 1 had done with the \>ig turtle last
summer. But then 1 didn't want to disturb an idyllic scene on
the pond. Also, it's not nice to disturb a mother ancj her
babes.

Luckily, there is a way to have my own turtle on my Color
Computer produce its own baby turtles. The statement to do
this is called HATCH, and I'll see if I can show you hqw it
works. First, think of a procedure — any procedure. For
example, the procedure for drawing a circle:

TO CIRCLE :N

Repeat 20 (FD :N RT 18)

END

(W, Bert Woofensburger [*'Uncie Bert**] manages a
hog and corn farm near Ypsilanti, Mich, He has
recently acquired a Color Computer and is learning
LOGO. Woofensburger 's editor and assistant. Dale
Peterson, writes for a living. His recent books include
"Genesis H: Creation qnd Recreation With Comput-
ers" and "Intelligent Schoolhouse: Readings On
Computers and Learning. "He is currently working on
a book about Color LOGO with Don Inman and
Ramon Zamora, to be published in 1984,)

Next, tell the turtle to go through the procedure, and have
a hatched tyrtje, or two or three of them, do the same. Like

so:

TO CIRCLES
SX 90 SY 80
HATCH 1 CIRCLE 8
SX 20 SY 170
HATCH 2 CIRCLE 3
SX 100 SY 100
HATCH 3 CIRCLE 5
SX 140 SY 120
CIRCLE 4
END

An even smarter way to do the procedure would be like

this:

TO CIRCLE :N :X :Y
SX :X SY :Y

REPEAT 20 (FD :N RT 18)
END

TO CIRCLES

HATCH 1 CIRCLE 8 90 80
HATCH 2 CIRCLE 3 20 170
HATCH 3 CIRCLE 5 100 100
CIRCLE 4 140 120

The last CIRCLE procedure doesn't need to be hatched
because that is being run by the mother turtle. 1 could have
called the last CIRCLE procedure

HATCH 0 CIRCLE 4 140 120

bepause HATCH 0 means the same as "no hatch,"and really
refers to the mother turtle.

Why did I put the mother turtle's procedure last? I asked
myself that — but I remembered my own mother, bless her.
When there was a bowl of potatoes on the table, who always
waited until the little darlings had their potatoes? Mother!
When there was spinach on the table, who always waited
until we had been served our spinach (even though we hated
spinach)? Mother! So it shouldn't be surprising that the
mother f urtle comes last here. Just for the sake of scientific
experimentation, I tried putting the mother turtle first in the
CIRCLES procedure. What happened? You try it, and see
for yourself.

TO CIRCLES2
CIRCLE 4 140 120
HATCH 1 CIRCLE 8 90 80
HATCH 2 CIRCLE 3 20 170
HATCH 3 CIRCLE 5 100 100
END

What I discovered was that once the mother turtle fin-
ishes, the whole procedure just stops — which means that
the hatching in CIRCLES2 never does happen. Now, if the
whole procedure stops when the mother turtle fmis;)i6s, we
may have another problem. Even though the mother turtle's
subprocedure is last in a procedure, what happens if her
subprocedure is simpler than the others, and she still finishes
early? I tried it:

TO SQUARE
SX 200 SY 40
REPEAT 4 (FD 20 RT 90)
END

May 1984 the RAINBOW 185

TO SHAPES

HATCH I CIRCLE 8 90 80
HATCH 2 CIRCLE 3 20 170
SQUARE
END

Again, even though the mother turtle may look (on the
screen) like all the hatched turtles, she is different. NV hen the
mother turtle finishes, the entire procedure stops, even if the
hatched turtles have not finished with their subprocedures.
Apparently, they "dehatch." Since it is simpler (takes fpwer
REPEATS) to do a SQUARE, the mother turtle finishes
first and all the hatched turtles stop working on their circles,
even though they haven't finished. It is most sensible, there-
fore, to give the mother turtle the most complex subproce-
dureand to place her last in a hatching procedure. Neverthe-
less, if for any weird and peculiar reasons you still wish to
give the mother turtle a simpler subprocedure than a
l^atched turtle has, you can tell her to VANISH — and she
vanishes once she has finished her subprocedure, while the
little hatched turtles are left to carry out their subprocedures
without maternal interruption. For instance:

TOSHAPES2

HATCH 1 CIRCLE 8 90 80

HATCH 2 CIRCLE 3 20 170

SQUARE

VANISH

END

Well, those were some of the things I learned about hatch-
ing. Then I began to wonder, "How many baby turtles can a
mother turtle hatch at once?" Like a hero, I was determined
to find out.

HATCH 16 WORMY 10 160
HATCH 17 WORMY 10 170
WORMY 10 180
END

I discovered some interesting things. First of all, it seems
that all the hatched turtles ignored my PC command. Only
the mother turtle changed the pen color. Second, all the
hatched turtles ignored my HT command. Strange! I
thought perhaps the H ATCH statement itself was cancelling
the PC and HT. I figured, and then thought maybe Pd try to
place the PC and HT within WORMY — that way they ^ be
called up right after eveiry HATCH. So I changed WORMY,
like so:

TO WORMY :X :Y
HT PC 2
SX :X SY :Y
REPEAT 5 (WORM)
END

I also discovered th^t the worms weren't moving all at
once. Clearly they were moving in a sequence. To get a closer
loqk at what was really going on, I slowed the whplc thing
down by placing a SLOW 100 command at the start of the
CANOWORMS procedure. You try it. What I discovered,
by running the whole thing very slowly, w^s that (correct me
if my eyes are deceiving m^) the way the Color Computer
draws when hatching is to move quickly from the one little
element of the subprocedure of one hatched turtle to one
little element of the subprocedure of the next hatched turtle,
drawing only a little at each stop. In other words, when the
computer is running at top speed, it may appear as if all
those hatched turtles are moving at the same time — but they
aren*t. That is an optical illusion. In reality, one hatched
turtle moves a little bit, then the next hatched turtle moves a
little bit, and so on, down the line.

Anyhow, I still hadn't found out exactly how many turtles
could be hatched for one procedure. It seemed clear from my
CANOWORMS procedure that at least 17 hatched turtles
could work together, but how many more were possible? My
little fingers were tired and so I decided not to test this any
further. Lucky 1 didn't, top, because about a day later one of
my spies told me I could have up to 254 hatched turtles!
Wow! Just imagine the CANOWORMS I could have done,
if I could have stood the typing!

^ But what really began to excite me was thinking about all
the fancy procedures I had done in the past, and then think-
ing I could have niy Color Computer do them wjth hatched
turtles. One for instance will do:

That was great, if I do say so myself. Watching all those
turtles moving at once made me think of be^s, though. So 1
decided just for the sake of it to try a honeycomb.

END

I should confess immediately that I made a mistake when
I first typed this up, and put a LT 120 at the bottom of
MOREMORE, instead qf LT 180, You might try that one,
when you have a chance. It's not a honeycomb, but it sure is
interesting.

Anyhow, I put the PC 2 in there just so we could know
where the queen bee is at alltimes. Unfortunately, the cjiiebn
kept being crowded out by her drones. That didn't seem
realistic to me. After all, the queen is the boss. 1 wanted to
say to the computer, "If any of the hatched turtles are near
the mother turtle, make them turn and move in a different
direction.^' In ttirtle talk, the instruction looked like this:

IFNEAR0<20(RT 120)

And I placed that instruction right in the earliest
subprocedUre:

TO HEXAGON

1FNEARO<20(RT 120)
REPEAT 6 (FD 10 RT60)
END

You might be slightly familiar with the conditional IF
statement because we used it before. The NEAR function
refers to the distance between whatever hatched turtle is

moving at the moment (the current turtle) and any design
nated turtle. In this case, the distance is 20 units (the added
value of X and Y distances), between the current turtle iemd
the designated tiirtle (turtle 0, the mother turtle). So I tried
that one out with my honeycomb. The results were . . .
interesting, and maybe they show you shouldn't fool with
Mother Nature. But, I kept right on fooling. First, I tried
reversing the less than sign (<) into a greater than sign (>).
Next, I tried increasing the distance value in N EAR, to see if
I could get the bees to spread out their honeycomb any
further. Finally, I tried adding more hatched turtles, and
changing some of the turn instructions.

Well, I know this is a shorter letter than usual, but to be
truthful, rm so excited about this hatch business 1 can't
stand it. I'm going to go back and try everything with
hatching! Maybe at last I'll produce some art that Sen
approves of. In the meantime, I remain.

TURN OF THE SCREW

Designing
A Video
Monitor
Output

By Tony DiStefano
Rainbow Contributing Editor

(Tony l)iStefano is well known as an early specialist in
Color ^Computer hardware projects. He is one of the
acknowledged experts on the "insides**of CoCo.)

A few months ago, when I wrote the article on how to
add a speaker to your CoCo, 1 mentioned that I was
not going to do an article on a video monitor output
for the CoCo. Well, 1 got a lot of letters arid phone calls
asking me to do one. The major complaint is that most of the
monochrome (black and white) video outputs do not have
enough gain to drive certain monitors. I thought this was
quite strange because 1 had made one from a schematic in
the Rainbow and did not have any trouble with gain. I
always had fjlenty of brightness and good contrast with my
Electrohome monitor. Well, just this week, I bought ah
Amdek 300A amber monitor, and guess what? My video
monitor adapter did not have enough gain to drive this
monitor properly. I thought there was something wrong
with the monitor. 1 brought it back to the place I bought it
and aired my complaint. They checked it out and told me
that the monitor was okay and that my computer was not
strong enough to drive this type monitor. It didnt take long
before 1 took my video monitor adapter and threw it out the
window. Now what was 1 to do? Humm! 1 guess I'll have to
design my own.

What follows is what I designed as a video monitor output
for the Color Computer. Following the schematic in Figure
1, you see a three stage amplifier. The first transistor is used
as an impedence amplifier. The second transistor is an
inverting voltage gain amplifier. The last transistor is lised as
an emitter follower. This adds the current gain necessary to
drive monitors that are terminated with a 75 ohm load, just
like the Amdek. It is not hard to construct this circuit. Yoii
will need all of the usual project tools like a soldering iron,
pliers, cutters, screwdrivers and the like. Get all the parts in
the parts list, though I think that most of you will have all of
these parts in your junk bin. There is nothing hard to get, but
do get all the right resistor values, close is not good enough.
You can mount it on a piece of perf board like in the list, or
you can mount it on just about anything. The output con-
nection can be made in many ways. You can drill a hole in
the back of your CoCo and install a chassis mount RCA
connector — Radio Shack #274-346, If you don't want to
drill a hole in your CoCo, just use a long wire with an RCA
jack on the end, or whatever type terminator your monitor
has. Most monitors have RCA terminators. You can mount
the board inside the computer with double-sided tape on top
of the RF adapter.

The . 1 uf capacitor in the parts list does not show up on
the schematic. This is a decoupling capacitor and goes from
the +5 volt line to ground. This is only to eliminate noise
generated from the power supply. This video monitor out-
put will work on any CoCo version, it will even work on the
CoCo 2.

Like usual, if you have some problems with my projects or
modification, or if you have a good idea you would like to
share with me, give me a call on any Monday night after 7
p.m. My telephone number is (5 14) 473-4910. If you want to
write to me, do so. If you need a reply to a question, include a
SASE. Till next time.

Submitting Material
To the Rainbow

Contributions to the RAINBOW are welcome from eve-
ryone. We like to run a variety of programs which will be
useful/ helpful/ fun for other CoCo owners.

Program submissions must be on tape or disk and it is best
to make several saves, at least one of them in ASCII format.
WeVe sorry^ but we do not have time to key in programs. All
programs should be supported by some editorial commen-
tary, explaining how the program works. We're much more
interested in how your submission works and runs than how
you developed it. Programs should be learning experiences.

We do pay for submissions, based on a number of criteria.
Those wishing remuneration should so state when making
submissions.

For the benefit of those who wish more detailed infor-
mation on making submissions, please send a SASE to:

EDUCATION NOTES

Swinging With Baseball
Interest Can Aid Educators

By Steve Blyn
Rainbow Contributing Editor

Computers beware! The baseball season is upon us.
Many a child's interest has turned once again to
America's other popular pastime.
What happened to all of the snow and ice? It seems like
just yesterday all of the students were throwing snowballs
and talking about the Winter Olympics. Now spring has
suddenly arrived and the talk has changed to baseball once
again.

As always, it is best to swing with the interests of the kids if
you want to introduce something new to them. This is
another good opportunity to learn or review a simple read-
data program. Baseball, of course, has teams and this leads
us to lists. List manipulation is a great introduction to data
processing for beginners.

Fortunately, baseball lists change often during spring
training and at the beginning of the season. This gives us a
perfect time to show the students how learning about the
computer can help them to keep their lists current.

At this point, we must confess that the staff of Computer
Island consists overwhelmingly of New York Met fans. It is
certainly hard for us to keep our baseball list current. We
still cannot recover from or even understand the loss of Tom
Seaver.

We will naturally illustrate this month's program using
the New York Mets as our example. You may alter the data
to any ball team you like. If you kids are on a Little League
or school team, their list will certainly be more appropriate
to your needs.

Let's start by first clearing some memory. Line 30 will
CLEAR 1000. This will most likely be enough for our pur-
poses and will also easily keep this program in the realm of
I6K. A higher CLEAR number can be used if your lists are
very extensive.

(Steve Blyn teaches both exceptional and gifted child-
ren, holds two master's degrees and has won awards
for the design of programs to aid the handicapped. He
and his wife, Cheryl, own Computer Island.)

Next we will dimension our list. We can use any number
that is greater than the possible total of players. This will free
us from worrying later on about keeping count of the
number of data entries. DIM A$(50) and B$(50) mllkecp us
well beyond the limit of players, even on the Mets spring
training roster. You may, of course, resort to a higher DIM
number if you require it.

The players' names and their positions will be entered in
DATA lines. The B$ represents the position. Familiar
abbreviations were used. For example, 28 stands for second
base and LF stands for left field. The A$ is the player's name.

The DATA is entered as A$,B$. You may put several
pairs on any DA TA line. A common mistake I have often
observed is putting a comma at the end of a DA TA line. This
indicates to the computer that there is an extra entry on the
line that you did not intend to create. A comma at the end of
a line will therefore cause an unintended entry of a blank
data statement.

The DA TA lines are read on lines 60-100. Notice that the
DA TA need only be read once in this program. Many
beginners feel that the DA TA must be read each time a new
search for players is made. Our computer is smart enough to
remember what it read once and use the information over
and over again for endless information-seeking purposes.

The very last DA TA entry is END, END. This is done so
that you do not have to keep track of the number of DA TA
entries. Line 60 tells the computer to look for 50 entries, but
line 80 tells the computer to stop read ing when it encounters
the name EN D. If you wish to add additional players to your
list, place new DA TA lines before the line that says DA TA
END, END,

Line 1 50 asks for a baseball position. Line 200 will search
out and print all of the players that play that position. If
none are found, the counter "NN" will be zero and a "Sorry,
None Found" message will be displayed.

There are many additions or options that could be
included in this program. We allowed for an End or Escape
key and an All players key. If *E' is pressed for the position,
the program will end. If *A' is pressed, all of the players will
be listed. If you have a printer, PRINTff'2 can be added to
lines 200 and 330 to get hard copies of your lists.

Hat

WOW! WHAT A PROGRAM!

Nowadays, when you go to the theatre, you first pay
your money and then go to the show ... and hope you
enjoy it. But it wasn't always like that. Centuries ago it
was the other way around. First you saw the show.
Then the performers passed their hats around. If you
enjoyed the show, you put money in the hat. The more
you enjoyed it, the more you put in.

We're going to try the same approach with
software.

INTRODUCING
PASS-THE-HAT
SOFTWARE

It works like this. Send us a formatted disk along With a
stamped, self-addressed mailer. We will use it to send you a
copy of SPELL'N FIX IL We also give you permission to
copy the disk as much as you want and give copies to all
your friends.

After you ve had a chance to use it, that's where the hat
comes in. We want you to decide for yourself what the
program is worth to you, and send us a contribution, (Hint:
send a LOT if you really like it!)

SPELL 'N FIX li is not just for
spelling mistakes — it catches
typos too. It really makes sure
that your word processing output
is perfect. Easy to use too. Reads
your text, fixes your mistakes,
lets you look up the spelling Of
bad words in its dictionary file,
even lets you add words to the
dictionary. Color Computer
Magazine called the original
SPELL FIX "a top-drawer
piece of software" ... and SPELL
'N FIX II is even better! Originally
advertised for $69.29, it beats the
$200— $300 dictionary programs
for other computers — hands
down!

Case Of Th6
'Overblown Heist

Scenario: YouVe a bank robber and you Ve just blown
your way into an underground vault. Unfortunately,
you overestimated the amount of dynamite required;
not only did you trap yourself in the vault, but the blast
triggered the external alarm (the police are on their way). It
did considerable structural damage. All but 15 moneybags
are buried in the rubble and they scattered intact. The inter-
nal alarms (immediate detection and capture on contact)
were also triggered. However, all is not lost; you have
enough dynamite to easily blast your way free to the open
exit, and since you're an enterprising soul (greedy), you're
going to make the most of it and grab some moneybags as
you blast your way through, hustling to get out before the
police arrive.

Objective: Get out in time with as many moneybags as you
can. You'll have to avoid the alarms as you blast your way,
nonstop, through three screens to do it.

Instructions: Enter PCLEAR6 before running the game.
To move your player, use the four arrow keys. Diagonal

(Doug Thorsvik is a captain in the U.S. Air Force. He
is presently an AFROTC instructor and teaches leader-
ship and management at Washington State University
and the University of Idaho.)

moves are possible and so is continuous movement by hold-
ing down the arrow keys. To pick up the moneybags, run
over them and avoid hitting the alarms. Use the space bar to
blast. Be careful not to blow away any moneybags (or
alarms for that matter). Pay attention to the yellow bar
timer on the left — when it's gone, you are too! Hitting or
blasting an alarm will get the same results. Exit each game
screen through the opening in the bottom right-hand corner;
you'll have to travel across three of them to get out. It will
take some practice and considerable skill to get all IS
moneybags, but it can be done. When prompted for your
initials, type in three letters only and they'll be displayed in
the lower right-hand corner with the high score.

This game uses the speed-up poke when drawing the three
game screens. If you don't want to use this poke, delete it
from lines 1, 33 and 65. If you want more time to get out,
change the ".6" in line 17 to a smaller number.

A Brief Guide To Using The Hi-Res Letters/ Numbers

IVe designed the graphic letters/ numbers routines to be
flexible and easy to use. If you want to use the graphics
routines in your own programs, here's hoW to do it.

Lines 37-42 have to be ruh to initialize the graphics before
the brief subroutines put them on the screen. Line 8 puts
numbers on the screen and line 9 puts letters on.

Before using the subroutines you'll have to indicate some
specifics:

Numbers: Presub info

ZN=number:ZI=x-coord:Z2=y-coord:Z5$=background
color :Z6$=color of number:G0SUB8

(Z 1 and Z2 must be odd numbers for the numbers to look
right. The routine draws from right to left, thus, Z1,Z2
specifies the lower right corner of the number to be dis-
played. The width of the screen is the only limit of the size of
the number. For an example, see line 22 in the listing.)

Letters: Presub info

ZL$=text (capital letters only) :Zl=x-coord :Z2=y-coord:
ZC=color of text:GOSUB9

(Zl must be even and 72 must be odd for letter to look
right. The routine draws from left to right, thus ZI,Z2
specifies the lower left corner of the text to be displayed. For
an example, see line 27 in the listing.)

The explanation is brief, so you'll have to figure out the
finer points on your own. This should give you a good start.

DO YOU mVE A 32K SYSTEM HITH 64K MEMORY CHIPS ?? ARE YOU STILL BEING TOLD YOU MN CM.Y USE 32K FROM BASIC ??

DON'T BELIEVE IT !! - KEY COLOR SOFTWARE brings you the Kl
any STANDARD 32K COLOR COMPUTER TO ACCESS €4K RAH FRf

*** Works with CASSETTE based svsteiis! ***

-264K. An exciting NEW SOFTWARE utility that allows
and wi th >I0 tMROHARE MODIFICATIONS REQUIRED! ! !

*** Works with DISK based systems! ***

The KEY-264K divides the 64K ran memry into two 32K banks or sides, each of which can be utilized independently
by the. BASIC interpreter, with the ability to switch instantly from one side to the other. IT'S LIKE WWING TWO
COMPUTERS IN GNE!! Have your ^SIC prosran on one side and keep your variables on the other side, or have your
nain prosran on one side and your subroutines on the other side, or have your prograi on one side and use the
other side for 4 additional HI-RES pages, or any conbination you like. The possibilities are endless because the
KEY-264K allows full comwnication between sides plus the ability to switch back and forth at will, all fron
within BASIC. You could also have different progrAs in each side and switch back and forth between then using
simple keystrokes, even while the prograns are running!! Or run them both at the sane tine in the
FOREGROUNO/BACKGROONO MULTI -TASKING node. Don't buy that printer buffer yet! With the KEYi264K you can be

Printing in the background side while utilizing your coa4)uter normally in the foreground side AT THE SAME TIME!!!
ebugging a program? Use either a BASIC coimand or single keystrokes to instantly duplicate your program, in it's
present status, on the opposite side. Switch to the opposite side later and pick up exactly where you were before!

For DISK users, the KEY-264K allows you to alternate between DISK and EXTENDED BASIC on the same si<te with
simple keystrokes. No need to pull your controller or power down. You can be in EXTENDED BASIC on one side and in
DISK BASIC on the other side and still switch back and forth and have full comunications between the two Sides,

The KEY-264K does this and MORE thru extensions to BASIC. No need to learn a new language! The KEY-264K adds
15 NEin^WIDS and 1 function to BASIC, including powerful new BLOCK MEMORY HOVE and GRAPHICS VIEWING commands.

The KEY-264K works on 32K systems with 'E", 'F', or even modified 'D' boards and requires EXTENDED or DISK BASIC
with GOOD e4K MEMORY CHIPS! Systems with piggy-back 32K or half-good 64K memory chips WILL NOT WORK! !

ORDER YOUR KEY-264K CASSETTE TODAY by sending check or money order for $39.95 plus i2.00 postage U.S.A.

REVIEWS

MANSION OF DOOM

Editor:

As a co-author of Mansion of Doom, \
would like to respond to Mr. Paul Gani's
review of our Adventure program on Page
230 of the February 1984 Rainbow.

Overall, his review was a fair (although
muddled) appraisal of this fine Adventure
program. However, some points need clarifi-
cation:

All Pal Creations Adventures have the
verb vocabulary built into the program to
make it easier for the Adventurer to get used
to the verbs used in that particular program.
If Mr. Gani kept using TAKE instead of the
accepted word GET, then Td say he has a
personal semantic flexibility problem. Other
Adventurers have had no problem getting
used to the verb vocabulary, especially since
the program tells you all the allowed verbs if
you use a wrong one*

All Pal Creations Adventures have the
instructions built into the program in order
to minimize constant referring back-and-
forth between the program and a piece of
paper. Also, with the instructions in the pro-
gram itself, it gives the player a better sense
of "being there," a very important part of
good Adventures. If this feature makes the
program unplayable on a 16K machine, so
what? Mansion of Doom has always been
billed and advertised as a 32K cassette
Adventure.

We appreciate Mr. Gani's PCLEAR tip
for disk users, but personally no one at Pal
Creations owns or uses a disk drive since we
specialize in 32K Adventures and simula-
tions on cassette.

We also decided against having a save
feature in our Adventures since most people
would rather try to solve an Adventure from
start to finish. If they can't solve it in one
night, then all they have to do is turn the
computer off, and they can try to solve it
another day. Then the next time they reload
it, they will know a little more of what to do
and what not to do. All of our cassettes are
of extremely high quality and can be reload-
ed time after time with no degradation in
tape quality.

But worst of all was Mr. Gani's reference
to a "bug" in the program. Pal Creations*
programs do not have bugs! If he had spent
more time reviewing the program, he would
have found clues telling him that "YOREL''
was the magic word to get out of the shack-
les, not "YORL"as he misprinted. And this
feature is not a bug, it was designed into the
program to provide a more magic-enhanced
Adventure environment. An Adventurer
needs all the help he or she can get when
battling against werewolves and vampires,
etc.

We at Pal Creations think that Mansion
Of Doom is an exciting, high quality 32K

Adventure and stand by its meager $14.95
purchase price 100 percent. We were amazed
that Mr. Gani thought it was overpriced
since marketing experts throughout the coun-
try keep urging us to raise the prices on all
our fine 32K Adventures to $24.95 and
$29.95 to be in the same price range as
Adventures that are inferior to ours. We will
continue to offer most our Adventures at
$14.95 in order to give TRS-80 Color Com-
puter owners extremely high-quality pro-
gramming at reasonable prices,

VIP TERMINAL

Editor:

One of the reasons that French food is so
good is that the French are merciless critics.
Thus, your often "goody goody** reviews,
obviously intended not to offend your ad-
vertisers, are a disservice both to your read-
ers and to improving the products.

The Color Computer is now maturing to
the point wher? there is some excellent soft-
ware atid worthy of such withering review.
But what do we get? Let's take the January
1984 review of the VIP Terminal program.
This program is certainly one of the best, if
not the best available for the CoCo ^nd eas-
ily worth twice the price. However, my copy
has some interesting features that did not
seem to be covered by Mr. Reed.

My use of this program has been strictly to
a host CDC Cyber computers (730 and now
835/855), Thus, my first annoyance is that
there is no way to reset the default parame-
ters along with autoloading the keystroke
multipliers (KSM ). My startup then involves
the program load, the ICSM load, and then
resetting the parameters. All this boring
detail could be avoided by simply allowing
the user to tailor his disk. The load itself
seems unnecessarily long since they seem to
have the initialization include reading a bad
track, and if it is faulty continuing the load.
They have the disk rigged so you cannot
write on it even though it appears (with the
help of their excellent ZAP program) that
very little is used of the total disk.

The next point is that the x-on/x-off does
not seem to work consistently in receiving
data. In the tests that 1 ran to the Cyber last
spring, 1 asked for my I/O to be recorded at
the host. The result was that in 51 -column
mode and 300 Baud, niy terminal would
send an X-off about half the time to suspend
host transmission; the rest of the time a
chunk of text would not be recorded.

If 1 get back into 32-column mode to make
sure 1 got all the text from the host, there is
no way to get back into 51 without getting
out of the terminal program. Even though
the documentation says that the parameter

table will always allow this, once you clear
the buffer and answer the prompt that you
waiit to get out of Hi-Res, the resolution
part of the parameter table never comes up
again.

Mr. Reed is correct that there are some
nice features in the disk handling part of the
program. One peculiarity 1 have encoun-
tered in the disk directory program is that
unlike the basic directory, the VIP Terminal
directory appears to scan every sector on
Track 1 7 beginning with the third. 1 am pres-
ently using a disk management program to
catalog and secure my disk dat^ which
duplicates the directory and granule tables
on Track 1 7. The granule table is duplicated
to Sector 1 and the Directory from three to
10 is copied from 12 to 17. Thus, the Termi-
nal directory gets two copies, and, if 1 have
killed a file without recataloging, then 1 get
the name of the killed file as well! (The disk
management program has a method of using
the backup copies to recover a file.

One feature which would be a nice addi-
tion would be to be able to change the print-
er mode without coming out of Terminal.
Thus some data you want to print out in 80
column and others, like FORTRAN compi-
lations, in 1 20-character mode.

1 mentioned in an earlier letter that I had a
problem with the printing of anything with
VfP Terminal (which also happened with
ZAP), The frustration was that 1 had no
problem printing using the POKE 150,18 for
my 2400 Baud interface with any other soft-
ware than Nelson's. The solution was a
retuning of the interface, but left me with the
implication that Nelson's was somehow
either more finely tuned or differently tuned
than that for the usual basic. Thus, 1 think
that those with slightly skewed Baud rates
would be better off if there was some mecha-
nism in the software that would let them
tailor their Baud rate to what works with
their equipment.

Joe Cain
Golden. CO

Editor:

1 must take exception with Jim Reed's
review of V/P Super Color Terminal, in the
January issue. There are some problems
with the disk commands in version 3.0 dated
June 1983. liTyoii have a disk with more than
28 entries, it is impossible to see the re-
mainder of the directory. This is contrary to
the instructions on Page 18 of the operators
manual, and apparently was not a problem
in version 2,0.

1 don't believe this is a major problem and
I'm sure Mr. Nelson, who obviously is a top
rate programmer, could correct this prob-
lem. However, I have written to Softlaw

206 the RAINBOW May 1964

Corp. detailing the problem, received a note
asking that 1 telephone their customer ser-
vice, which 1 did. 1 was then told that they
would check on this problem, and never
heard from them again. As a matter of fact,
the customer service representative didn't
even want my name or address, which
obviously indicated there was no intention
of giving me a reply.

I think the VIP Terminal is a fine pro-
gram. However, the support after the pur-
chase is completely lacking. If the other pro-
grams use the same minimi isk operating
system, Til have to be assured that 1 will not
encounter the same problem.

It seems that Mr. Reed is a friend of Tom
Nelson, who is a contributing editor to
Rainbow as well as general council for Soft-
law Corp. I feel sure that there is no way Mr.
Reed or Rainbow would publish a bad
review of any Softlaw product.

It should be pointed out that the disk is
copy protected which makes it very difficult
to try and fix it yourself.

John Spataro
Lynn Haven, Ft

Editors Note: The Softlaw Corpora-
tion (formerly Nelson Software Sys-
tems) ho longer copy protects its pro-
grams. This means that VIP Library
programs now can be backed up. This
should alleviate several of the afore-
mentioned problems.

OWLS EYE LIGHT

Editor:

In reference to the review on the Owls Eye
Light in your March issue, I installed an
Owls Eye on my computer and it looks like
original equipment. It is one of the best
investments I made for my CoCo. Yes, you
have to Unplug it to use the joysticks — big
deal. It fit my computer fine. Looks good
and works great.

Did your reviewer really hook it up or did
he gue^s at how it worked?

Mark Widuch
Princeton, IL

Editor:

1 felt 1 must reply to the review in your
March issue on the Owls Eye Light.

First, the ad states it plugs into the joy-
stick port so 1 had anticipated the joysticks
would not work with it. Some of us conipu-
ter nuts use our computers for more serious
things then playing "Pac Man'* games any-
way.

Second, 1 have the old style computer with
the RAM button and it fit fine.

Third, 1 don't think the reviewer even
installed the light. In the package it doesn't
look like a lot but when installed, per the
instructions, it looks like a part of the
computer.

1 have a light kit that mounts in the joy-
sticks. If you have a candle lit in the room

you can't tell If it is on. The Owls Eye can be
seen in bright sunlight.

You are giving a good product a bum rap
with your review.

PHONICS II

tditor:

This letter is directed toward the March
1984, Page 242, review of Phonics II. a
sound-letter association program which uses
the unique ability of the Color Computer to
direct audio instructions and prompts from
a cassette tape recorder through the speaker
of the TV to the user, in this case, students
just learning to read.

The review was subtitled, *'Only Phair,"
presumably for two reasons which the re-
viewer mentions. First, he states that the
tutorial mode of the program does not
require any student participation, after
which he mentions that the program "does
expect the studeht to repeat aloud the di-
graph sound with the narrator. "That sounds
like student participation to me. In addition,
the current release of Phonics II (version 2.0)
also requires that the student type the con-
sonant digraph before going to the next
audio prompt. More student participation.

The second "disappointment" the reviewer
mentiohs is with the single sheet of instruc-
tions. If he had taken the time, he might have
noticed that the program was well docu-
mented within itself. For instance, points at
which decisions are to be made within the
setting up of the program parameters have
the option "NEED MORE INFO." Select-
ing this option brings forth screens of infor-
mation useful in making parameter choices
(a nice touch, 1 thought, siqce many people
misplace or won't read the documentation
which comes packaged with the software).
Perhaps the reviewer would have preferred a
"user-hostile" program with reams of docu-
mentation necessary to render it under-
standable.

On to more important criticisms, The
reviewer states that the instructions were
confusing because the program description
follows brief loading instructions and a very
short warranty statement. He says that he
likes to know about something before he
attempts to use it. By the way, the instruc-
tions he talks about are on the inside of the
package. If he had bothered to read the
information, which we conveniently placed
on the outside of the package (so people
wouldn't have to guess about what's on the
inside), he would have seen a similar pro-
gram description!

As the coordinator of software evaluation
and computer-delivered instruction of an
elcinentary school of over 500 children and
the author of a courseware evaluation in-
strument used by at least two school districts
in Tucson, 1 attempt to evaluate software on
the basis of its educational merit and useful-
ness with children (witness my review of
LOGO in the December 1982 edition of the
Rainbow).

I would limply ask that all software (mine
included) reviewed by the Rainbow be
judged on that basis, rather than the degree
to which its packaging conforms to the per-
sonal tastes of the reviewer.

Incidently, anyone desiring a copy of my
software evaluation form should send a
S.A.S.E. to 8370 E. Lee, 85715

GRAPHICOM

Editor:

My thanks to Paul Hoffman for a very
kind review of Graphicom. There was one
technical error in his review that must be
corrected. In his advice to readers on what
parts to get to make your own custom joy-
stick or foot pedal for Graphicom, the
author directed the readers to use a "five-pin
DIN connector" for the joystick port» This is
wrong. The joystick port requires a six-pin
DIN connector. Radio Shack, on its joy-
sticks, uses a six-pin DIN plug that has been
altered by having its center pin removed.
Though the resulting plug has only five pins,
they ar^ spaced quite differently from the
spacing of the pins in a true five-pin DIN
connector. Worse yet, while true ftve-pin
DIN connectors are readily available at
Radio Shack, the necessary six-pin DIN
connector is not available.

The required six-pin joystick plug should
be available from local electronic supply
houses. If you have trouble finding a source
of six-pin DIN connectors, you can pur-
chase two (used but in excelletit condition)
of them for $5 from us at Cheshire Cat.

I personally highly recommend that pur-
chasers of Graphicom make their own cus-
tom joysticks. We have come to prefer a
joystick made Using a Radio Shack joystick
mechanism (Cat. No. 271-1705) mounted in
a small chassis box (3!4 x 2 x 1 in.) with
two buttons mounted along the 3 14 by I J4
inch side. Such a box is not available from
Radio Shack, but is available from supply
houses handling LMB chassis boxes. The
alternative of using a footswitch for the
menu button is not quite as good, but it does
work reasonably well and is much simpler to
construct.

My one overall criticism of the review was
that it made Graphicom sourrd a lot more
complicated to use than it really is. While it
does take a bit of getting used to, once you
learn how to control the program, drawing
proceeds extremely quickly and simply. 1
invite any sort of comparison of how long it
takes to draw a given artistic picture and a
given technical illustration to be made be-
tween Graphicom and any other existing
CoCo graphics drawing program. I'll eat my
hat if any other program allows general pur-
pose drawing that is even a quarter as fast as
Graphicom i.

Model I I III Emulator
Should Be Quite Useful

When the Color Conlputer first came out, a lot of people
were asking if it could run Model 1 software. Theanswer, of
course. Was no; the CoCo is far too different from the M ode!
1 and 111. The Microsoft Extended BASIC languages are
quite similar, though, so the only thin^ stopping many
BASIC programs from running on the CoCo is the very
different screen display and character set.

Spectrum Projects' 64 Column Model Ijlll Emulator
produces a 64 by 16 text displijy using the P MODE 4 high-
resolution graphics mode. The screen memory is placed in
the upper 32K of RAM, so 64K memory is required. The
character set (in the range 32 to 191 decimal) is almost
identical to the Model lll*s, though the actual character
shapes are very different. The block graphic characters are
available, both for PRINTing and normal point graphics
(using S'fr, /?£5'£rand POINT). A Model l/lll BASIC
program will run on the CoCo with the emulator if:

— it is written entirely in BASIC ahd does not use PEEKs,
POKES or USR calls (all the locations are different);

— it does not use basic commands or functions that are not
available in Extended Color BASIC (such as DEFDBL,
DEFSNG and DEFINT); and

— it can be loaded into tlie CoCo (if you are willing to type it
in). Since the CoCo's cassette and disk file formats are
different from those of the Model I or III, you will have to
have some special program on one machine or the other
to bridge the gap. Another way would be to send the
program over the RS-232 serial I/O ports (if you have
RS-232 in the I or III) as an ASCII file; you'll need
RS-232 cables on each machine, a "gender-changer"
adapter to connect the two male DB-25 plugs and (on the
Model III) a null modem adapter, (What I have to say
about the Model 111 gbes for the Model 4 as well, assum-
ing you are using it in Model III mode.)

The display is rather hard to read, as 64-cblumn Hi-Res
displays usually are. The characters are only three pixels
wide, and are plagued with the notorious false cqlors of
PMODE4, (Of course, you can almost always turn the color
level down to get rid of the color fringes.) The PR/NT ^
command now has a range from 0 to 1023 to match the
Model 1/ Ill's screen locations; SET, RESET and POINT
now run from 0 to 127 horizontally and 0 to 47 vertically. If
you want an expanded text display simply for your own
programming, the emulator will serve reasonably well as
none of the CoCq's BASIC commands have been removed.

The 64 Column Model Ij III Emulator should be quite
useful to those who have been running BASIC programs on
the Model I and III, although the text display has its
problems.

DOUBLE DOS BASIC

364,000 BYTES!

That's right! Using your 64K Color Computer, and an 80
track drive, you too can have more than TWICE as much
storage on your disk drive system. DOUBLE DOS BASIC
allows you to use 35, 40 or 80 track (double or single sid-
ed) drives all on one system, all at the same time! Your
system could consist of a 35 track drive, a two drive
AMDEK system, and an 80 track drive, all working, and
hooked up to your system! (The AMDEK drives are 40
track drives.) ALL commands are supported in DOUBLE
DOS BASIC. The DOS is totally transparent to your
BASIC programs! If your system selection is 80 tracks, a
PRINT FREE command will return 158 granules! Com-
pare this to the 68 granules your system now returns! The
40 track drives would return 78 granules, 10 more than
the 35 track system. EVERY command in BASIC is sup-
ported by DOUBLE DOS BASIC. If you haven't already
upgraded to 64K, now is the time! Use your system to its
FULLEST! DOUBLE DOS BASIC also gives you RESET
PROTECTION, unlike most of the other 64K programs.
AND, used with our ROM MOVE program, you can also
get another 8000 bytes of BASIC addressable memory!
DOUBLE DOS BASIC - $24.96
DOUBLE DOS & ROM MOVE - $24.96

Whole Numbers And Decimals
Handy Aids For Teachers

Whole Numbers and Decimals are education software
programs designed to prepare printed worksheets for any
number and variety of mathematical problems. Designed
and distributed by Shamrock Software of Radnor, Ohio,
these programs provide welcorned m^iterial for the class-
room teacher- The programs are designed to give practice on
addition, subtraction, multiplication and division of whole
numbers or decimal numbers. Please note that these pro-
grams are sold separately.

The program contains a series of subroutines used to
formulate each problem type. The programs are written in
BASIC language and instructions are given for ways to alter
the programs for varied use. This is a welcomed feature and
not provided by many software distributors. The changes
need to be made prior to running the program because the
[PREAK] key and the list command will be disabled when
the program is run. You can restore the list function by
POKEing 383,0 as mentioned many times in this magazine.

The programs are printer-oriented and the math prob-
lems generated by the programs are not listed on the video
screen. Thus, if you do not have access to a printer, you will
find this program rather frustrating.

The programs print an actual worksheet of mathematical
problems. You have the options regarding the number of
problems generated, the range of numbers used (up to 9999),
and the number of worksheets printed (each one is differ-
ent). If you want multiple copies af the same worksheet, you
would need td use a copier. The answers are given on the
worksheet and designed to be left on the sheet as an aid to
the students, or they can be cut off and used as a checklist for
grading.

The programs can be used for any age group because any
limitations can be utilized. For example, for first graders,
simply use numbers less than 10, and adjust the program for
addition ohly. For high school seniors, use numbers in the
thousands and mix subtraction with (Jivision. Working with
decimal numbers is always a little more complicated than
working with whole numbers.

The programs are Very basic in nature and are cut and dry.
There is no title screen, no mUsic, and no bells and whistles.
The programs should run on a 4K machine with standard
Color BASIC. This program could be used by teachers or
parents who waqt to help their children brush up their
arithmetic skills. The documentation is short, but adequate
for the operation of the software.

The Investor — A Good Idea,
But A Good Investment?

How would you like a program that will analyze your
stock portfolio? Just enter your purchases and sales of
shares, dividends taken in cash or reinvested, commissions
paid, and splits. You can enter up to 175 transactions
divided among 24 different investments. In return, you'll get
an up-to-date display showing your current cost basis and
market ' value, realized and unrealized gains and losses,
shares purchased and sold, shares purchased with reinvested
dividends^ annualized rate of return, and other goodies for
each stock. YouH also get grand totals for your entire port-
folio, and weighted averages and comparative bar graphs so
you can compare your holdings and see how each one con-
tributes to your overall position. That's what The Investor
will do for you — but with some difficulty.

The program actually comes in two parts. The first pro-
gram on the tape, INVUPDT, is used solely to enter your
dat4 into a file and write the file to a cassette. Then you
CLOAD the second program, INVESTOR, and input the
file from the data cassette. This second program is the one
that gives you all the answers.

That can be a bit of a nuisance when you have several
transactions to enter, and some of them happen to be sales of
mutual fund shares, for whiph, unlike other securities, the
cost basis is generally figured on an average cost rather than
on the first-in-first-out method. So you have to stop and

write your file to tape, read it into the second program,
calculate your cost basis, and then read the file back into the
first program and enter the sale.

I dont know why J & A Enterprises chose to do it that
way. Neither the cassette label nor the instruction manual
has an address or a phone number, so 1 couldn't call theqi to
ask, I can only guess that it was the only way they could fit
the program into 16K and have enough memory to handle a
reasonably large number of records. I'd rather have a single
self-contained program that requires 32K.

The instruction manual — three 814 by 1 1 sheets folded in
half to make six pages — carefully illustrates each screen, and
describes the various menu options. Most of the essential
information is in there somewhere, biit youVe got to go
through it carefully several times before starting to enter any
data or youll waste a lot of time and effort doing it wrong.
The manual could be greatly improved by the addition of a
summary section and some mention of defaults.

After you enter each record, you are asked "IS DATA
CORRECT (Y/N)." Guess which one is the default condi-
tion. I found out the hard way after keying in several records
that didn't get into the file.

If you change your mind while keying in a record, there's
no exit key to return to the main menu. Either you finish
keying it in and then go through the delete process, or you
[BREAK], if you [BREAK], where do you get back in
without losing your data? 1 figured out the right line by
listing the program, but a business application of this type
should be usable by someone with zero programming
knowledge. If you must [BREAK], then at least the manual
should tell you where to GOTO.

To enter a purchase or a dividend reinvestment, you nlust
put in the dollar amount, the cost per share, and the number
of shares. If the number of shares is not correct, based on the
first two variables, the entry will not be accepted, and the "$
AMOUNT" prompt will come up again. This may be a silly
question, but if the program has already calculated the
number of shares, why in the world does it have to be
entered?

Changing or deleting a record is more difficult than it
needs to be. All fields must be reentered even if only one is
incorrect. The record to be changed is located first by
account number and then by date. If you have more than
one transaction in the same stock on the same date, there
seems to be no way to change the second one without
deleting the first one.

If your portfolio includes mutual funds, as mine does, you
may occasionally receive a capital gain distribution (either
cash or reinvested in shares) along with your annual divi-
dend. TJie Investor makes no provision for these.

Error trapping should have been better. I read a file full of
incorrect data into the Second part of the program, and
when I selected one of the comparative graph options, it
crashed oh an FC Error. I believe that a well-written pro-
gram should never b^ crashed by bad data. It should either
give an answer of some kind, however wrong it may be
("Garbage in, garbage out"), or display a "data out of range"
message as a signal to the user that there may be some fault
in the entry of records.

There's no doubt that TJie Investor is a very good idea for
a program, but 1 wouldn't buy it in its present form.

Excitement, Realism
Mark SAC Text Game

A wargjimer once said, on being accused of being a war-
monger, that "the study of war no more made him a war-
monger than the study of cancer made a research physician a
cancer monger. "The recent revulsion for all things military
has been partly to blame for a void in one of the most
stimulating areas of simulation and gaming, human war-
fare. This void has been partially filled by SAC, a real-time
nuclear flight mis$ion simulation.

SAC requires a 32K Extended CoCo. Its premise places
you in the cockpit of ydur B-52 on the ready pad at Ramstein
Air Base, Germany. Suddenly, the tower orders you to
scramble and gives you take-off information. Your fingers
fly as you start the big ship's eight engines, advance them to
full power, release brakes and begin your take-off roll. After
lift-off, you receive information about your assigned target
and a fail safe code which must be used to arm your plane's
single nuclear bpmb. From this point you use your naviga-
tional computer to fly to your target, bomb it, return to
Ramstein and land. Sound easy? It's anything but.

In the immortal words of one M^jor ^'King" Kong (pilot
of a B-52 in the movie "Dr. Strangelove"), "Well boys, it
looks like this is it . . . noocleeeur combat, toe to toe with the
roooosskies." All the way to and from the target yoii will be
hounded by MlGs and SAMs bent on turning you into a

charred scar on the Russian landscape. You are far from
defenseless, however, for your B-52 is equipped with nine
sophisticated navigational and weapons systems including
missiles and a chaff dispenser for thwarting MIGs and elec-
tronic counter measures to avoid the radar of Soviet SAM
bases. Some of these systems may become damaged due ,to
enemy action and must be repaired by the flight engineer,
which takes a varying aniount of time. You haven't felt
excitement until yoUVe screamed in on a target at 600 KTS,
rapidly approaching the drop point, while the F/E tries to
repair the bomb ragk in time to drop the bomb. The last
thing you want to do is to maKe a second run ori the target.
Dropping the bomb within five miles df ground zero results
in the target being destroyed.

This is a text style game, not an arcade. All aircraft
conditions and combat reports are in text (a la Star Trek)
but it is still real-time and the action is fast. 1 feel that more
realism is possible in this $tyle of simulation. There is one
very nice graphics feature, however. It is a PMODE4 map of
Russia which you can toggle anytime you want it. It is very
nicely done and it shows the position of your B-52, all 36
possible targets and Ramstein.

Primary aircraft control can be selected prior to starting.
You can select keyboard only or combinations of keyboard
and joystick. I preferred the keyboard only mode as 1 felt it
provided better control. Difficulty is selectable also and
ranges fron) "A piece of cake" (the easiest) to "Orte way trip"
(the hardest). If you are in a vengeful mood yOu can even go
after Tehran.

Documentation is good and completely covers all asj)ects
of the simulation, from take-off to touchdown,

I liked this one a lot, it is exciting and realistic. It also has a
sobering aspect that makes one hope that this never really
happens — at the same time, you gain a new respect for
those men who are faced with the task if it ever does.

Small Letters On CGP-115

This may be of interest to anyone who ahs the CGP-1 15
printer. It changes the size of the print from 40 columns to 80
by using the printer's built-in C//7?5f/<5j command instead
of by using the DIP switches in the back. Also, it seems to
speed things up a bit.

To place the printer in the srinall letter mode, one must
first type in PRINn-2XHR$(18) and [ENTER]. Then
type in PRINTU-2rit^C and [ENTER], No\v type in
PRlNn-2,CHR$(l7)[^mEK\ and then type in PRINT
#-2, "test" [ENTER] again. This should place the printer in
the 80-column mode and print the word "test" in small
letters.

Let Your CoCo Spell
With Color Dictionary

It's nice to see Radio Shack increasing their Color Disk
library. Their newest edition which 1 received to review is
Color Dictionary. It comes in their familiar thrQe-ring
binder, as do Disk Scrip$it and Disk Spectaculator. Upon
inspecting the binder, something surprised me — an insert in
the beginning o\ the book. This insert is also the same one I
found jn my copy of OS-9, It is entitled "Read Me First'' and
continues:

All Computer software is subject to change, correction,
or improvement as the manufacturer receives tustom^
er comments and experiences. Radio Shack has estab-
lished a system to keep you immediately informed pf
any reported problems with this software, and the
solutions. We have a customer service network, in-
cluding representatives in many Radio Shack Compu-
ter Centers, and a [a rge group in Fort Worth, Texas^ to
help with any specific errors you may find in your use
of the programs. We will also furnish information on
any improvements or changes that are "cut in" on later
production versions.

The reason for quoting this notice is that 1 can finally give
credit to Radio Sh^ck for offering quality after-market sup-
port for the Color Computer. They are finally recognizing
the importance of their product and (hopefully) see it as a
long-term investment. With this sheet comes a registration
card that is filled out and mailed to Fort Worth. The sheet
also contains a space for a Version Log and the version
purchased is listed already. Both the versions of Color Die-
tionaryand OS-9 are 01. 00.00. 1 like this idea and 1 hope that
Radio Shack has made this their policy indefinitely.

The manual is laid out in the same format as Disk Scripsit
or Spectaculator leaves none or very few questions to ]>t
asked if the manual is thoroughly read. The program cpmes
with two diskettes. Ohe is the dictionary and the other the
system disk. Although much easier to use with two drives,
the program will work with only one. Color Dictionary is
written by Robert G. kilgus, the same author who wrote
Disk Scripsit, so it wasn't unusual to see the same type of
operating system implemented. In fact, the first menu that
appears after typing' RUN** DOS*' is the same menu that
appears irt Disk Scripsit if selection 8 i^ chosen to "Return to
BAS|C."There are five choices: 1) Return to BASIC; 2) Run a
Program; 3) St^rt Clock Display; 4) Display Free Space
Map; and 5) Copy a File, These all work the same way as in
Disk Scripsit. At this point the manual informs you to make
a copy of Disk Scripsit onto the diskette you are using for
Color Dictionary. (Note: A backup copy of the system disk
and the dictionary disk should have been made by now, and
the originals stored away!) This is done by choosing option 5
and copying the file "SCRIP/ BIN." What Kilgus has done is
incorporate Disk Scripsit with Color Dictionary to be able
to switch back and forth between each other. Vm not sure
how he accomplished this, but when ip the main menu for
Disk Scripsit, the program will no\y allow you to press the

number 9, which will send you back to Color Dictionaryl It
onjy works if they are on the same diskette. Now all of your
Scripsit files can be transferred to the Color Dictionary disk
and you can go from Scripsit to Dictionary and back by
using menu selections. Note that menu selection 9 does not
appear on the Scripsit menu, but it is there.

Option 2 at the main menu allows yog to run a program.
To get to the next menu of Color Dictionary, select optiort 2,
then type "CHECK" [ENTER] and the second menu will
appear. Us choices are: I) Lookup; 2) Check Spelling; 3)
Correct Spelling; 4) Go To Scripsit\ and 5) Return to DOS.
Lookup i$ a great feature. With it, you can search the
dictionary for any word, words, group of letters, words
beginning with certain letters, ending with pertain letters,
and so on. For example, if you wanted to see all the Wor(ls
that begin with the letter "z,"ybu would enter **z*," the
being a wild-card character giving the whole z section of the
Dictionary. You could also type "zoo*" or any amount of
letters. The other wild character the program uses is the
question mark "?." While the stands for any amount of
letters, the "?" stands for only one, although more than one
can be used in a search. A good example is if you fprget
the spelling of a word. Let's use the word "receive." You
can't remember if the "i" is before or after the •*€," You
simply enter "rec??ve" and all the words in the Dictionary
that have "rec"at the beginning and "ve"at the end and are
seven letters long will appear. You cpuld have also typed
"rec??ve*" and words that match that are seven letters or
longer would appear on the screen. If the question mark is
used as the first letter, the entire Dictionary is searched for

matches. (The process can be stopped at any time by hitting
[BREAK].) After the list has appeared on the screen, you
have the option of printing it or hitting [ENTER] to con-
tinue. One note. Color Dictionary does not have a section to
set the Baud rate of your printer. There are two options here.
One, insert a line at the beginning of the "DOS/BAS"
program to POKEyour Baud rate, or go to Scripsit from the
Color Dictionary and set the Baud rate from Scripsit and
return to Dictionary. This lookup feature will be a joy to
anyone who does any kind of word puzzles. With a 60,000
word dictionary at your fingertips, finding the right word to
fit should be a breeze.

Of course, there is another powerful feature of this pro-
gram to check and/ or correct your spelling from a Scripsit
document. These are options 2 and 3. After pressing 2 at the
menu, the program asks for a filename which should be on
the disk you are using or you will need to switch disks before
you enter a filename. The filename is assumed to be in
Scripsit format with "/TXT*" as an extension (default). After
entering the filename and placing the Dictionary disk in the
appropriate drive, the program proceeds to search through
your Scripsit file and check each word against its dictionary.
The "suspect" words (words that are not in its dictionary)
are displayed and can also be printed. When this is com-
pleted, selection 3 from the main menu corrects the spelling.
Each suspect word is shown and you are asked to enter the
correct spelling, skip to the next incorrect word or return to
the main menu of the "CrtECK" program. If a mistake is
made when correcting, you are given a chance to change it
again, making this part of the program very easy to work
with. Upon completion of all the changes, you can resave the
file using the same filename or by entering a new one.

Color Dictionary will prove to be a great asset to any
Color Disk Scripsit user, as well as anyone who just wants
the program for finding words using the wild card character
searches. Among its drawbacks are that words cannot be
added or changed in the Dictionary, meaning it cah't be
customized. For us Canadians (Canuks!), the Canadian
spelling of certain words has been left out. For example,
"colour" as opposed to "color." It does have quite an exten-
sive list of words, and most forms of words are included,
including most plurals, which are always listed directly
below the root word, although it may not be in alphabetical
order.

DRB Utility
Is Reasonably Priced

If you own a disk system, you have probably discovered
by now that the DIR command leaves a lot to be desired.
Not only does it scrpll the file names off of the screen, but it
also does not give you all that much information about your
files.

The latest offering to tackle some of these shortcomings is
DRB (Directory with Bytes). DRB is written in BASIC and
will work on a 16 or 32K machine.

When you RUN DRB, it asks you if you would like your
directory displayed on the screen or printer. If you choose
the printer option, the program checks to make sure that it is
ready. If it is not, it will let you know and then END itself.

The directory display produced by DRB includes the
information you are used to, plus it will show you how many
bytes long each of the files are. If the screen should fill up
while displaying the directory, the program will pause and
wait for you to hit the space bar. Once all of your directory is
displayed, the program will also display the number of free
and used files, granules and bytes on the disk.

When 1 first ran DRB, I thought to myself, "Oh, that's
nice,"and decided to try it out on another of niy disks. When
1 typed in /?C/A^ again, all 1 got was an OK. It was only after
loading the program again that I discovered that it does a
A^£W^ after it is done. Why, I don't know.

DRB comes with another program called "DSKNAM."
What this program does is allow you to put a name on your
disks, which will then be displayed along with the directory.
It does this by storing your name in the last eight bytes of
track 17, sector 18, which is not used by RS DOS.

All things considered, DRB is, at best, an interesting
utility program. Despite the fact that it is very reasonably
priced, most of you could probably write it yourself in an
hour or so. If you have never written a basic program, and
have never read your disk system owner's manual, then you
might want to consider buying it. Otherwise, a "do-it-
yourself" project would be yoUr best bet.

Cultivate Action, Fun
With Demon Seed

With such a large amount of software available for the
Color Computer and so many variations of each, it is some-
times difficult to decide on what to purchase. In the area of
popular arcade games, there can be as many as six or eight
different versions from assorted companies, so you can flip a
coin to decide what to purchase or, instead, pick up the
Rainbow and go through the reviews to help you make up
your mind. So pull up a chair right next to me and we'll boot
up this program together and take a look.

Confiputer Shack has released a new arcade game called
Demon Seed. The object is to protect the world from the
demonic forces that want to take over the universe, or
something like that. You, brave warrior, must (as usual)
save the (pick on^ of the following): world, cosmos, earth or
your pel hamster from this evil. Do you have what it takes?
Are you ready? Can you handle it? Do you want to turn the
page?

When the program appears on your magic tube, the first
thing you will see is the title screen of Demon Seed. If you
would like to watch the demo mode for awhile, jUst leave it
alone. Otherwise, hit the [ENTER] key to begin the game.
As the game unravels the first wave of bats will swoop down
on you against a black background. You may fire upon them

by pressing the button on your joystick, or defend yourself
with the available shields by moving the stick forward.
When you bring up a shield you become immobile for awhile
until the energy of the shield wears off. The shields last about
six seconds, so be ready to move again. You can fire through
your shields if you want. Also, the amount qf shields given to
you are unlimited and you don't have to "s^ve'Uhem for the
harder rounds.

During this first waVe you may only have two shots on the
screen at any given tittle. The second found is identical to the
first pile with the bats, but only one shot on the screen is
allowed. Each Screen will end once you have killed off every
intruder in sight.

The graphics and game play improve considerably when
you reach the next level. Here, the visual effects are colorful
and very smooth. Small eggs forni on the screen and swarm
left and right, back and forth, growing right before your
eyes. Whoosh, swoosh, lik0 a slithering snake. Then they
hatch. The Demon Seed. Wicked wings flapping furiously,
blue 4nd red and yellow. They fire upon yoti randomly,
quickly, sometimes machine gun-like.

They swoop down at yoii, on you, past you, and return
again at the top of your screen. You need quick reflexes now.
Shoot a wing off. Wl^ichever one you hit grows back in a
short time. If you shbot both wings off, the demon turns
back to an egg.* Tuff stuff, eh? If ydu hit the demon squarely
nght between the eyes you finish him off. The sound of the
shots and hi^s are electronic, These third and fourth rounds
use the s^^me firing principle. Two shots on the screen the
first time around and one for the second,

If you have survived this far, you have the privilege of
blowing away (pick one): the mother ship, the flagship, your
landlord or your citizenship to save face and the world.

There it sits, waiting silently, suspended in the darkness of
space and your living room. Our old friends, the bats, arrive
for a return engagement to hassle you. You fire at the
bulkhead of the ship, putting a dent in it at best. The ship
slowly starts to descend, giving you less time to avoid the
shots beiilg fired from the ship. The middle portion serves as
a rotating protection device to disperse the damage you
inflict, so you must continue to aim for the same spot when it
comes around a couple of times to finally open up a channel
and lay waste to the king baddie hiniself. Get in one clean
shot and whappl The ship explodes all across your screen
and you can start all over again.

Another feature of the game is a display of the high scores
of the evening. You can also pause for some fresh air or
restart the game anytime ypu want,

I should like to point out at this time that the disk 1
received for review was copy^prptected. When you purchase
Demon Seed^ yo\x will not be able to make a copy for your
backup files. Neither the backup nor copy commands \yill
work. Also, as the program loads, the disk head travels back
and forth at least eight times to achieve a load ^vhich I feel
brings about unnecessary wear and tear on the disk drive
unit. I also think the disk would wear out sooner than
normal because of this.

All in all, Demon Seed is a good arcade gailfie that will
grow on you. It is available in 16K and 32K versions.

A Guide To Food Contents
Gives Nutritional Information

For those trying to lose weight, or for others looking to
eat a balanced diet, the search for proper nutritional infor-
mation often leads to piles of magazines and stacks of
books. A Guide To Food Contents is the first attempt by a
programmer to cover this area for the CoCo.

Available on tape or disk, the program requires 32K
minimum for use. A one-page instruction sheet details con-
cisely the program's operation, which is simple and direct.
The program loads in three parts. The first section puts up a
screen listing the abbreviations used in the program and
loads "Part 1." Parts 1 and 2 run in an identical manner,
showing a menu listing the food categories covered in that
parti and giving the option to load the other part. Part 1
covers vegetables, fruits, meat and poultry, and fish and
seafood. Part 2 gives information on milk, cereal products,
cakes and puddings, spreads, etc., beverages and alcoholic
drinks.

After choosing the desired food category, a listing of
individual foods is given, each prefaced by a number. It is a
good idea at this point to have a paper and pencil to jot down
the numbers of the foods you intend to look up, as this can
save a lot of frustration going back and forth from the listing
to the menu to the listing and then to the screen searching for
your particular food item. The listings are for the most part
alphabetical, but this varies with each food category.

After you have compiled the list of reference numbers tor
the particular foods in your chosen category, you will be
asked to enter a number, or to press [ENTER] to return to
the main menu. When the number is entered, the name of the
food is listed, often with a qualifying remark (boiled, fried,
raw, etc). Below that is the listing of contents, as below:

BEEF, HAMBURGER (2.6 oz.)

cal,195

wat.l37gr

pro,l 1.3gr

fat,15.8gr

carb,1.5gr

vit. A, folic acid, Bl, B12, niacin
min, iron, phosphorus

Sometimes there is some minor confusion, caused by
slight differences in food description (i.e., "beef, chipped,"
chosen from the food category becomes "beef, chopped" in
the listing). The greatest problem, though, is not due to what
is in the program, but what is missing.

It is possible to use this program to find information on a
number of individual food items, but a number of very
important items, both individual food items and even cate-
gories, are missing. In individual foods, there was no listing
for skim milk, french fries or baked potatos. No mixed
foods, such as pizza are given, no soups, and no breads and
very little in starches. The lack of these common foods
would seem to make diet planning somewhat difficult.

In testing both tape and disk versions, the tape proved
easy to use, running with no problem and to my full satisfac-
tion. The disk did cause a problem, though. The first section
loaded with no problem, but when Part 1 would begin to
load the disk drive would just light up and do an imitation of
a Mazda (instead of going "click, click, click," it just sat
there and "Hmmmmmm"ed). As 1 could not load it, I could
not LIST to find the error. A friend found that by using a
well-known processor (Nelson Software Color Writer II) it
was possible to "read" the disk, and so found the problem.
There was a "speed-up" POKE in the second line of both
Parts I and 2. Two computers, a stock 32K "E" board and a
home upgraded 32K "E" board, each had this problem, but
removing the POKEs allowed the program to load and run.
Even without the "speed-up," the program was, in effect,
instantaneous, so its removal was not a detriment.

A Guide To Food Contents lives up to its name, providing
a useful quick reference to many food items. A little more
polish and perhaps the addition of some foods not included
in the guide would raise this from an interesting guide to a
real tool, to be used in diet planning.

Business A ccounting System
To The Rescue

By Bruce Rothermel

From early morn' to setting sun, this humble reviewer is
the Director of Marketing for a manufacturer of power
tools. The accounting functions for the company are per-
formed by a group of bean counters and number crunchers
affectionately (?) referred to as the Sales Prevention De-
partment. They magically feed numbers into our HP-3000
Computer which spews endless reports on reams of greenbar
paper. With corporate sales of over $200 million dollars, this
immense accounting group is necessary.

However, after the pinstripe suit is returned to the closet, 1
become the President, Chief Executive, Head Honcho,
Boss, and entire staff of a small home-based business called
Cobra Softwear. No, that's not a misspelling. 1 have a mail-
order business which sells Mustang and Cobra emblem La
Coste golf shirts to owners of these exceptional vehicles.

What started out as a very small operation has progressed
into a real business. And my previous methods of account-
ing — shoving bills into one drawer and checks into another
— has become woefully inadequate. To my rescue has come
the Business Accounting System (BAS) from Mark Data

Products.

The BAS is a family of programs which operate interac-
tively. They require a CoCo with at least 32K RAM, and
80-column printer and at least one (two preferred) disk
drives.

On loading BAS, the Mark Data Super Screen program is
executed converting the TV screen to a 51 character by 24
line display, a great improvement over the standard screen.
The operator is presented the program menu, which lists the
options available to the user. When a task is selected, the
CoCo loads the program to handle that task from the system
disk. This modular system reduces the amount of memory
required. When a transaction is completed any pertinent
data is automatically transferred to the data files of the other
programs in the BAS.

Using BAS, you can create, update and maintain data
files and prepare the necessary accounting reports including
transaction journal, a P&L or income report, and an interim
or trial balance and a balance sheet.

Operation is similar to standard manual accounting
procedures with the CoCo providing assistance during each
step. An understanding of accounting fundamentals is help-
ful; however, the documentation and self-prompting screens
walk the user through the basics of getting the system going.

The system is shipped with dummy data loaded on the
disk. The first part of the 3 1-page instruction manual takes
you through the basics of starting the system, entering trans-
actions and printing reports. After getting familiar with the
system by working with dummy data, you get into the meat
of the program by customizing the supplied Chart of
Accounts for your business.

The Chart of Accounts then becomes the heart of the
accounting system. A Chart of Accounts is supplied which is
so complete that it could be used by many businesses with-
out change.

I found that is was too complete for my needs. I didn't
need all the accounts furnished so 1 deleted many of them
and added a few to meet my specific use.

The Accounts are grouped into the following classifi-
cations:

Assets
Liabilities
Equity
Sales

Cost of Sales
Operating Expenses
Other Expenses

This accounting system observes the rule — the sum of all
assets must equal the sum of all liabilities plus the sum of all
equities. Each transaction must affect two accounts. The
computer insists on it. In fact, the message "Assets = Liabili-
ties -{- Equity'' is displayed at the top of the screen as each
data record is reviewed.

While the 10 programs included in BASmitv^ci with each
other to create one system, an explanation of each program
may help you to understand the capabilities of the total
system.

1 ) START — reserves the required disk buffer space and
calls the SETUP.

2) SETUP — program which sets up proper printer
operation and loads and executes the Super Screen pro-
gram. SETUP then requests the "workdrive" number 0

The actual operation of the BAS program is easier to do

My little shirt business is now set up on BAS and a
biweekly run of the system will help me keep one of my New
Year's resolutions — to get organized. It will also be of great
value at the end of the year when tax time rolls around. My
accountant will love the printed reports and a running audit
trail for all sales and expenses.

The only difficulty I encountered was that the Super
Screen program included in BAS is not documented. Error
messages are given in numerical code rather than in the
two-letter alpha code the CoCo usually uses. Mark Data has
stated that a Hsting of the error codes will be included in
future shipments. 1 would prefer full documentation, but an
explanation of the unique error codes is a help.

The Business Accounting System is not inexpensive, but
considering what it can do to organize a small business, it is
quite a value.

Software Re¥lewi

Number-Kruncher
Good For Basic Math

When 1 first unpacked my Color Computer, I typed in a
program called "Drawing Board" from the Radio Shack
manual. This program makes colored lines on the screen
when you press the arrow keys. My wife's unappreciative
comment was: "Wonderful, now we own a $500 Etch-A-
Sketch."

The program Number- Kruncher, from Moonshot Acres
Software, is sort of like that. It gives your several hundred
dollar computer system all the power of a $10 pocket calcu-
lator. Number- Kruncher allows you to key in a number,
select an operation, and then key in a second number. The
two numbers and the answer are all displayed simultane-
ously in a box in the center of the screen. It requires 16K of
memory and Extended Color BASIC.

While you might sometimes want to use your computer
like a calculator, this program is too limited to be useful.
First of all, it has only the four basic functions: addition,
subtraction, multiplication and division. No square roots,
trig functions, or other advanced features. Second, the for-
mat of numbers used is very restrictive. Numbers may have,
at most, six digits to the left of the decimal point and, at
most, two digits to the right of the decimal point. The
program does permit chaining of operations and can hold
one number in memory. The program provides several
screens of instruction and help screens to remind you how to
use the program.

The documentation suggests that you might want to
incorporate this program into your own software. One sug-
gestion is to use it as an on-screen calculator for a financial
application, like an income tax program. But Number-
Kruncher is too limited to do even the simple calculations
you'd want in an income tax program. For example, the
income tax rate in my state is 2.2 percent. Since you're only
allowed two digits to the right of the decimal point, you can't
multiply by .022, and so you can't calculate the state income
tax.

All in all, I can't imagine any reason to buy this program.
Editor's Note: Moonshot Acres Software advises us
that a percent function has been added to Number-
Kruncher and that present owners are being mailed
patch instructions.

Beam Rider — A Colorful,
Energizing Chase Game

Spectral Associates has done it once again folks. Beam
Rider is not only pleasing to the eye, but is also a lot of fun to
play. Because of the many different ways that one can play
the game, young and old alike will find it hard to stop trying
to find new screens, gain higher bonus scores or to just see
how long they may be able to survive.

As is the case with all of Spectral Associates programs, the
loading instructions are very Clear and easily understood.
You will need at least 16K RAM (Extended BASIC is not
required) and one joystick. If you are using a cassette sys-
tem, type CLOADM and [ENTER]. With a disk system
type LOADM and [ENTER]. When you receive the OK
prompt type £'A'£'C and you will be presented with the title
screen, which is also the high score screen. To begin play,
push the fire button on the right joystick and you will be
jumped to the first screen.

Each screen or board contains blocks (blue) arranged in
different patterns that must all be cleared off before one can
proceed to the next board. Each board also has three
characters:

1 ) The bea mer (white solid circle) which you control with
the joystick.

2) The red chasers, which follow your beamer around the
board attempting to get in your way whenever possi-

ble. Coming into contact with one of the chasers when
your beamer is not energized will destroy the beamer.
On the first board there is one chaser, while all of the
rest have two. The chasers start off slowly, but as you
clear the blocks from the board, they get faster.
3) The spinner (white spinning circle) which moves about
the board at random, if your beamer or the beamer's
energy beatn contacts the spinner in any way it will
destroy your beamer. Whenever the spinner touches
one of the blue blocks, the block becomes multicol-
ored and for a few seconds (while it is still multicol-
ored), it will be art energizer.

Clearing an energizer causes your beamer to become
energized. While you are energized all point values are
doubled and the chasers cannot destroy your beamer. While
energized a bar will appear at the top of the screen. This
gives you about seven seconds of energy. When this is gone,
the bar will disappear and yoiir beamer will be vulnerable
again until you are able to clear another energizer. If you are
able to beam through a chaser while your beamer is ener-
gized, you will be awarded 1000 points and the chaser will be
immobilized for about 1 .5 seconds. Each time an energizer is
cleared the bonus counter will increase by one and when the
current board is cleared of all the blocks, you will receive a
bonus of 1000 times the tiumber of energizers cleared. An
additional beamer is given for each 50,000 points scored.

There are three basic ways to approach this game. The
first is to go for only as many points as possible, not worry-
ing about clearing boards. (1 was able to score over 160,000
on the first board this way.) The second way is to clear as
many boards as possible, not worrying about the amount of
points scored. (A friend was able to get to the sixth board
this way.) The third method of play is the obvious combina-
tion of the first and second methods. Score as many points
as possible early in the play of a board and then trying to
clear the rest of the board before the chasers can get too fast
aiid trap your beamer. There is a fourth method that 1 have
discovered, but I will nbt reveal it here. I am, at this writing,
in a bet with my brother-in-law for the championship of the
family and 1 don't want to give him any advantage in the
final playoff!

Each board is differertt. 1 don't know how many different
boards or screens there are, but I wouldn't be surprised if
there were about ten. Some of the boards are good for
scoring points, while others are better for just running and
trying to get to the next board without dying. All of the
boards have a very pleasing symmetery or design.

1 particularly like the way the red chasers have a blurring
effect when they become very fast. The destruction of your
beamer is an event that has to been seen and heard to be
believed! The sound of your destruction is like a tomato
hitting the wall and as if that isn't enough insult, when your
beamer is destroyed it goes to pieces, bouncing all over the
bottom of the screen!

Overall, this game is easy to play and learn, but offers
enough of a challenge to make any dedicated gamer an
addict in one short evening. The graphics are well done and
the sound effects are functional without being a nuisance.
(Just don't go to pieces!)

Get The Real Sound
mth Spell-A-Tron

As voice packs for the Color Computer gain popularity
and additional users, (see November '83 Rainbow), more
programs are being released which take advantage of its
speech capabilities.

For those not familiar with CoCo voice packs, a quick
review. The voice pack is a ROM-type cartridge which plugs
into the ROM pack slot. When a machine language program
containing a text processor and a dictionary are loaded into
memory, your Color Computer can then speak words and
phrases contained in basic language programs.

The resulting speech is slightly electronic with a Swedish
east-coast accent (to my west-coast ear). 1 refer to the result-
ing voice as Uncle Sven.

An ideal application of speech capability is spelling test-
ing programs. Since the computer can pronounce the word,
it is unnecessary to "flash" the word on the screen or use
audio tapes which make it difficult to change the test words
or the order of the test words.

Jarb Software has released their Spell-A^Tron program,
designed to assist children in mastering their spelling words
with the assistance of a 32K minimum Extended BASIC
CoCo, a voice pack using a Votrax SC-01 synthesizer chip
and DEI Software's Translate program. (For this review 1
used Spectrum Projects Voice Pak and included software.)

Spell-A'Trpn consists of two separate programs. Spelling
and Wordmaker. Spelling is the spelling quiz maker. After
loading the program and a user specified word file, the
following options are offered :

1) Hear and see all words

2) Hear and computer will speak all words

3) You spell the words you hear

4) Load a new wqrd file

In the "Hear and see all words" mode, the computer will
pronounce the word, display it on the screen, and pronounce
the word again.

In the "Hear and computer will speak all words" mode,
the computer will pronounce the word, then display and
pronounce each letter, and then pronounce the word again.

In the "You spell the words you hear" mode, the computer
will pronounce the word to be spelled twice and then accept
the student's response. Pressing the [/] key repeats the word.
If the correct spelling is given, the student is congratulated
and given the next word to spell. If the incorrect spelling is
given, the student is asked to try again. After three incorrect
tries the correct spelling is given. After all words are pre-
sented, all incorrectly spelled words are displayed for
review.

The second program, Wordmaker, is used to create cus-
tom word files used in the first program. Spelling, The word
file contains each word in two forms, the word correctly
spelled and the word in phonetic form. Wordmaker offers

1) Enter spelling word

2) Find a word

3) List word file

4) Sort word file

5) Create word subfile

6) Load word file

7) Save word file

The enter spelling word mode is the main workhorse of
wordmaker and offers the options of:

1) Enter pword

2) Save pword

3) Speak pword

4) Delete pword

5) Main menu

Pword means phonetic word, the string that is passed to
the voice synthesizer. In most cases, the spelling word and
pword will be spelled the same, however some words have to
be misspelled for them to sound right when spoken. Televi-
sion is tell-a-vision phonetically. Using Wordmaker, the
word is pronounced and you just change it until it sounds
right and then save it.

Spelling and Wordmaker can hold up to 200 word? in
each file.

A textfile called Tronlist is included on a separate tape. It
contains about 200 words in the sixth grade to adult cate-
gory.

In use, the program works fine. The student is asked to
spell the test word which is pronounced twice. The ability to
repeat the word by pressing the [/] key is very helpful. On
some words in the Tronlist file, 1 had difficulty determining
the pronounced quiz word. Vowel sounded a lot like foul.
To eliminate these sound-alikes, 1 used Wordmaker to
change the pword to overemphasize the accents and add
spacing. Submarine became sub-m^-rine. It is very easy to
play with the pwords until they $ound right to you.

1 just returned from a trip to many cities across the coun-
try. After sampling speech patterns in Boston, Dallas, New
York and Los Angeles, I am sure different pwords will be
used in different areas of the country for the same spelling
word. 1 found the different speech patterns to be delightful.
Here in California, a "Yawl" is a fore-and-aft rigged sail-
boat, in Texas the same pword is used as a greeting, i.e.,
"Y'awl have a good day!" What 1 am trying to get to is that
you can have your CoCo pronounce the word the way you
say it.

In summary, Spell-A-Tron does a good job of giving a
spelling quiz. It does not keep score; proper spellings are
rewarded with "Right," "Correct" and "Super" responses
being said to the user. The only improvement I would sug-
gest would be adding some interesting graphics to the screen
to hold the interest of younger students.

To display any portion d memory in any of Coco's 26 documented display modes, and to move
ttirough memory using the arrow keyi To slow the action to a crawl, or freeze it at witt. Instantly
switcti between watching the output of your program and watching Peeper dynamically display
(on screen or printer) the contents of the 6809's registers and stack, showing changes as they
are happening In the slowest speed mode. Peeper provides continuous singl^stepping; faster
modes give a coarser trace. Or, halt the action and single-step by repeatedly pressing the space
bar Peeper supports breakpoints, memory examine/change, and more. Tliink how much easier it
wouid be to modify someone else's ML software if you could determine what routines were being
executed at any given point!

For tun, (and this requires no ML experience), use Peeper with arcade games, watching the fine
details of the animation effects in slow motion. See how the game looks and plays in other
graphics modes. Or watch what is happening on "hidden screens" you never see, (Makes a
superb demonstration.)

New Friction Option
For Printers

When I was deciding to buy a printer, one of the most
important aspects that I had to consider was whether 1
wanted the "Friction" option. All printers have the usual
"Tractor" mechanism, and if you desire the added conven-
ience of using single sheets of paper, such as stationery, your
personal letterhead or whatever, the cost is usually around
$100 extra.

Now, for those of you who have bitten your fingernails
away completely because you now wish you paid the extra
scratch for the friction feature, a cheaper (but sturdy) way to
get the same results is available for any printer. It's called the
Paper Tractor.

The Paper Tractor is a flexible plastic device that is
inserted into your tractor mechanism and will carry your
single sheets of paper through without any hassle.

To use this handy device, you just place the paper you
would like to use in and under the half-inch folds provided
on the top, right and left hand sides of the "tractor."The fit is
snug and the paper will stay firmly in place. Then just thread
it over your printer sprockets as though it was your usual
tractor-feed paper.

You may align it at this point, checking to make sure that
your print head is at the desired height on the paper. Then
just print as normal.

One precaution you should take while printing is to make
sure that you do not go past the end of the paper and onto
the device itself, or worse, onto the platen of your printer. If
your printer has a "paper out" detector, it will still function
as usual.

Even though my printer has friction feed as a standard
feature, I tried the Paper Tractor as described and it worked
beautifully. The samples I ran were at 9600 Baud and bi-
directional, which I thought might have had a negative effect
because of the speed and irritation to the Paper Tractor, but
it came out beautifully.

After using the tractor a couple of times, 1 found that I
could even print on the very last line of my samples since the
Paper Tractor itself extends into the paper-out switch
because of its length.

The only inconvenience 1 can imagine is that if you intend
to print an awful lot, the time needed to withdraw the Paper
Tractor and insert new sheets of paper will slow things up a
bit.

The Paper Tractor is a handy complement for you non-
friction printer owners. It handles up to 1 1 x 14 paper, will
work with any printer, and can be used instantly by anyone.
The documentation provided does not actually explain how
to use it, but if after looking at the photos provided you can't
figure it out, you shouldn't be near a computer, anyway.

Atom — Fast Action
With A New Twist

When 1 took chemistry in college a few years ago, the
worst part was trying to memorize the periodic table of
elements. It would have been bad enough just to memorize
the abbreviations of 103 different elements, but some of
them (like "Pb" for lead) are based on Latin names and have
no apparent connection to the common name. (My mother
told me a cute way to remember the symbol for one element;
when you think of antimony, think of alimony and then
remember the ''Sb" who's paying it.) Depending on the field
youVe in, you might remember a few from the names of
various combinations that you come across (like NiCd for
nickel-cadmium batteries or HCl for hydrochloric acid), but
remembering the whole list would take a lot of work and, by
the time you get all 1 03 down pat, a few more may well have
been discovered!

Radio Shack's Atom is actually an educational tool dis-
guised as a fast-action arcade game. The object is to
maneuver a gravitron around a nucleus, pick up orbiting
electrons and fire them into the "electron holes'' on the inner
ring surrounding the nucleus. By doing this, you build up
atoms of different elements, starting with hydrogen and

working up through the table. (For various reasons, the
game uses only the first 54 elements.)

The only controls you have over the gravitron are moving
it in a circle around the nucleus, moving inward and out-
ward and picking up and firing electrons. The game's great-
est problem is that the directions of movement are those seen
from the gravitron 's point of view and not the directions that
you see on the TV screen. This makes it very difficult to
move around, as the direction of movement on the screen
doesn't match the direction in which you point the joystick.
(Yes, 1 know that this method is scientifically correct; it
works well if you are able to see the field from the point of
view of the gravitron, but you can't.)

The manual uses something akin to a split screen;
throughout the book, the top half of each page is devoted to
a lesson about the structure of atoms while the bottom half
contains the game instructions. Another nice touch is the
large wall chart of the periodic table, done in a science-
fiction style with the symbols placed in a picture of an atom
complete with a gravitron "gunship" carrying an electron.

Atom would be a terrific game if the controls were easier
to handle, but as it stands it takes a lot of practice just to
keep from crashing.

The Sourcerer
Bares All

A lot of the more advanced hackers have a great interest in
finding out how a particular program works. With machine
language programs, the only way to find out is to disassem-
ble the program (unless you have the extremely rare talent of
being able to decipher code in your head). One guy 1 know
has file drawers packed with disassembled listings of every
program he has in his library. (Td hate to have his bill for
printer paper!)

The Sourcerer, from Computerware, is billed as "proba-
bly the most powerful disassembler" for the CoCo. It is
capable of sending its source code to the screen, printer or
tape or disk files. In the most basic operation, you simply
specify the starting and ending addresses and let it rip. The
resulting source listing can be entered into an assembler to
regenerate the program that you are dealing with. If (and it's
a big if) you can figure out the workings of the program, you
can modify it to suit you and then reassemble it.

One flaw common to all disassemblers is that they can't
tell whether a particular section of a program is actually
machine code or if it's a table of messages, values or what-
ever. The Sourcerer has a Zap mode that finds those areas
that are not valid 6809 machine code and displays them; you
will still need to figure out what they are (and which "valid"
instructions really are not) yourself. The Long mode gives
you a. listing of the machine code together with the corres-
ponding assembly instructions, while the Symbolic mode
gives you the assembly statements only (which is the way
that you would enter them into an assembler).

The cassette version (which 1 tested) comes with a pro-
gram called the Apprentice, which simply finds the loading
and execution addresses of a binary file from tape or disk.
The disk version has a FIND program which does the same
thing as Apprentice 'and a COM PA RE program that checks
to see that two files are identical and prints a table showing
where they differ.

The Sourcerer is a very effective disassembler for the
CoCo and should be a great help to any assembly language
fanatics. Those of you who use OS-9 will be happy to hear
that an OS-9 Sourcerer is also available.

Taxi Ride
Fairly Smooth

Children's Computer Workshop has developed a series of
programs for Radio Shack with a goal "... to create
software that is wholesome and engaging, encouraging
children to play constructively and learn actively.'* Taxi is
one of the games in the seven- to 1 0-year age group focusing
on cooperation and strategy. The three- to six-year-old ser-
ies is for " Basic Pre-School Skills" and the 1 0 and over scries
stresses '*creative exploration."

Taxi is designed to allow one or two players to drive
around various cities while picking up fares, earning pay-
ment and getting tips.

The game is suited to one player but is designed for two
children to develop an understanding of cooperation and
strategy in picking up their fares and thus earn more money
and higher tips. The two-player "company" works towards a
higher score through cooperation — helping each other with
spotting fares, dividing up the city into sections and driving
carefully without running red lights and getting fined or
getting into accidents.

Trying out the game with two sets of youngsters (David,
10 with M ike, 1 2 and Jennifer, eight with Sarah, eight) gave

me insight as to whether Tq^i does what it claims. It does.
Both sets of children truly enjoyed the game and did start
developing a system to make more money. Cooperation was
evident from explaining the introductory instructions to
each other to playing the game. The first time around, an
adult was needed for suggestions. But after that the children
were on their own.

The game design, with high resolution graphics and
sounds, is excellent. The children were enthusiastic in play-
ing and kept at it to improve their scores.

The program, as good as it is, has some problems. These
problems deal not with the game, but with the execution.
The worst of the problems is the loading time. The introduc-
tion loads in a respectable 28 seconds. When RUNy a poem
and then a high resolution taxi picture are put on the screen
while CLOADing another 28 seconds. The directions ask if
you want instructions. If you answer yes, it takes almost a
full five minutes to load. The children had a hard time
controlling themselves waiting this length of time. Remarks
such as, "This tape is too long" and "1 don't believe it" were
made. In a classroom setting a teacher had better have
something for the children to do during this load. At the end
of the load (providing there are no I/O Errors), the screen
asks a series of questions. How many players? Do you want
to practice? We practiced and the program gave a sample
screen of city blocks, taxi, and fares to pick up and where to
drop them off. The practice is almost a game by itself. The
child also learns how to position the joystick to drive and
pick up passengers by centering it (the new self-centering
joystick by Radio Shack would be good in this game). When
the practice is completed, you have the choice of practicing
again or continuing with the game. We continued and it

took 32 seconds to load the game introduction. You are then
asked a series of questions, including how many players, taxi
speed, what kind of traffic, long or short game. You have
choice of three cities, Dallas, New York, and San Francisco.
Since this is on tape, it is wise to go in numerical order,
otherwise yo\x are instructed to rewind the tape and start
over. The city loaded in at 23 seconds and then the high
resolution graphics loaded in at about 45 seconds. We could
then start the game.

The screen shows the city on the top five-sixths of the
CRT and the bottom one-sixth includes a game time (about
three minutes), plus a separate fare and tip total for each
player. When the game is over, a chart shows how well each
player did and shows gross total minus fines, for net total of
the company. You can also get a chart of the individual
player's totals.

The next fault with Taxi is the instruction booklet. The
authors did a superb job of drawing high resolution graphics
of the cities. Being an ex-New Yorker, I spotted the Empire
State Building, Kennedy Center, the Twin Towers and St.
Patrick's Cathedral. IVe been to San Francisco and recog-
nized landmarks there, though I cannot name them. Dallas,
well, I can tell you J. R. is not included. And this is the flaw.
Nowhere in the instruction booklet is there an explanation
of the city graphics. What a shame! Even the streets are
modeled after the street designs of each city.

The booklet, while going into excellent detail about load-
ing and playing the g^me, and even activities, does not
mention how muqh RAM is needed. My CoCo is 64K but I
do not know if this game will work on a 16K machine.
Extended BASIC is required. But do not have your disk
plugged in or the game will not work. The game uses auto-

start and will cause problems with a classroom networking
system. With such a long loading time this would cause
difficulties for a teacher having to load computers individu-
ally from a recorder.

My general overall feeling towards Taxi is positive. My
recommendation is that it is worth the money. However, 1
hope the authors develop future programs that will be disk
driven, and include complete explanations for directing and
graphic screens.

Responses To Queries
In Question And A nswer

There are many programs on the market that drill chil-
dren in addition and subtraction. Question And Answer,
from Moreton Bay, not only acts as a drill, but an actual
teaching tool. It works with the concepts of numbers that are
equal, greater than and less than, as well as providing prac-
tice in addition and subtraction. There is also instruction in
the computer techniques needed to answer the questions.
Question And Answer is actually a series of programs, each
dependent on the skills learned in the preceding program. It
is written for a 16K CoCo with Extended BASIC.

The first program in the series is called Step 1. In this
program the child learns how to use the program and also
the kinds of responses that he will need. Practice is provided
in completing simple numerical equations like X + Y = ?, in
which the child enters a number, or in deciding if a number is
equal to another number or greater than a second number.
This is done through the keying in of True [T] or False [F].
Step 2, the next program, is like Step I except the concept of
"less than" is introduced.

Step 3 introduces more complicated problems in which
the numbers before the equal sign are to be entered, e.g., ?+
Y = Z.

Step 4 instructs the child on how to enter the symbols =, >
and <. The problems can now take on the form X + Y ? Z or
X - Y ? Z.

The last program is called QAA. It is a summary program
which incorporates all the instructions and practices all the
skills used in the first four steps. In Steps 1 through 4, the
numbers are all one digit. In QAA, the numbers can be up to
four digits long, depending on the skill level.

After CLOA Ding Bind RUNning the chosen program, the
user is asked to wait while the rest of the program loads,
after which he is asked to [ENTER] his name. He then has
the choice of being instructed on the skills ^nd keys needed
to use the program or proceeding to the mathematical prob-
lems. The skills are taught in a clear and concise manner and
the child cannot go on until the questions are answered in a
way that shows conceptual understanding. 1 find the exam-
ple used to teach a child what "True" means, unfair to many
children. If the child using the program is named Johnny,
the statement "Johnny loves Santa" is displayed. The child is
expected to respond with "True" [T]. If he does, a screen
appears that says, "Santa loves Johnny, too!" There are
many children for whom Santa Claus is not a part of their
life. A response of "False" [F] to this statement produces a
screen which displays, "I'm so sad Johnny doesn't love
Santa." I feel that this kind of statement produces feelings of
being an outsider for the child who does not believe in Santa
Claus. I think a more appropriate and universal statement
should have been used.

When the user gets to the part of the program in which he
has to solve problems, after the problem is displayed on the
screen, he is told what kind of answer he needs to input. For
example, if the problem is 3 +4 =?, he is told to respond with
a number. If he answers correctly, a screen appears which
graphically displays "RIGHT!" or a happy face. An incor-

C Compiler Version 2 for color computer
OS-9 DOS for color computer
Relocatable Assembler for Flex and CoCo DOS

C Compiler

Dagger's Growing Systems C is the original C Compiler
for the 6809 and is the proven leader in the field. It is a grow-
ing subset of the C programming language. It runs in 20K,
has assembly language output, position independent code,
an extensive library in assembly language source, and code
optimizer.

The Color Computer and Flex (which will run on the
Color Computer) are now both available with full floating
point package (float, long, for, goto, etc.) in addition to
the basic C commands. CoCo Dos also contains features
which use the BASIC ROM functions (els, polcat, partial
floating point, etc.).

Dugger*s Growing Systems has the cost effective C
for OS-9. It contains all the necessary C commands (while,
if, if else, int., char, etc.) which may be linked, loaded,
and used in a multi-user, multi-tasking environment.

Relocatable Assembler

The relocatable assembler package includes assembler,
linker, and manager. May be used with the Color Computer
or Flex.

Symbols up to 32 characters □ Many special characters
allowed in symbols ($, %, etc.) □ Multiple files assembled
without exiting the assembler □ Direct output to printer at
any time □ Generates either absolute or relocatable mod-
ules which are linked together with RLINK to generate exe-
cutables □ Supports two types of global variables ( VAR and
COMN) Fortran type common □ Compatible with source
for most assemblers □ Macros with parameters □ Condi-
tional assembly.

Linker

Use text-like files which are generated by RASMB or any
other source □ Allows inclusion of multiple source files,
each of which can have any number of program modules
□ Provide for library files, whose modules are included
only as required □ Specify at link-time execution address
and global storage area for easy generation of ROM-able
code □ Will link together both absolute and relocatable
modules □ Extensive linkage information output on request.

Manager

Provide a tool to build a *Mibrary" of re-
locatables □ Edit feature to list, insert,
and delete modules.

rect answer produces a graphic "NO!" (rather harsh) or an
unhappy face. After every five problems, a scoreboard
appears. To end the use of the program, "S" is inputted when
a problem appears. This causes a final scoreboard to be
displayed.

The documentation recommends that if the child is a
beginning reader, an older child or aduh will be needed in
getting the young child started. After the child has mastered
the concepts being taught, he should have no trouble using
the program by himself.

There is no limit on the time needed to work out a prob-
lem. A child should be encouraged to use paper and pencil or
any other tools he may need in order to find the answers. In
the last program, Q A A, the child or the adult can choose an
appropriate skill level. A number between 1 and 1000 is
entered. This is a bit much. It is difficult to distinguish the
difference between skill level 250 and 25 1 . However, it's nice
to see a program that allows a child to work at his own pace
and at his own level.

According to the documentation, the correct answer will
be displayed after an incorrect answer has been given.
Unfortunately, this is not the case. Learning is definitely lost
when a child cannot find out what his mistake was.

Another flaw in Question And Answer is that when the
answer requires a number and characters other than numbers
are entered, the answer is considered incorrect. I would
much rather see an error message displayed and the problem
repeated. It is just too easy for little fingers to hit the wrong
keys by mistake.

I especially like the fact that teaching a child how to use
the computer is incorporated into the program. There is so
much learning going on in these programs that I found
myself overlooking most of the things that are wrong with
them and concentrating on all the things that are right.

Software Review ^SSSSSSSS^SSSSSY^

Math Invasion
Adds Up

Having three grade schoolers, I can appreciate the value
of a good educational program, and that is definitely the
category for this program.

Math Invasion is loaded by an auto-load, auto-start pro-
gram. Anyone who has bought much software has seen this
loader. The title screen is d isplayed while the program loads,
and from the title page the computer starts a demonstration
of how the game is played.

Once you have seen the computer play the game, you can
try yourself by touching any key. This leads you to a menu to
select the home galaxy of the invaders: Addition, Subtrac-
tion, Multiplication or Division. Once this is done, you must
select one of three skill levels. Now you can start to blast the
invaders, but unlike other invader games, you must load the
gun with an answer to one of the invading problems. Using
the numbers on the keyboard, the answer must be fired at
the proper invader using the right and left arrows and the
spacebar. There are four invaders on the screen at all times
trying to get to the surface of your planet. As the game
progresses, they come faster and faster. One point is given
for each right answer and one subtracted for each wrong
answer.

Although this game uses low resolution graphics, it is an
extremely fast, clean program that gets and holds the atten-
tion of the child playing the game. This simple-to-operate
program gets the job done. Math Invasion is worth its
weight in gold to anyone with children learning math.

Adventure At
20,000 Leagues

Have you ever wanted to go deep-sea diving in search of
treasures lost centuries ago; the cargoes of hapless ships, who
set sail and were never heard from again? It's a fantasy that
has infected each of us at one time or another. But the
practicalities of life forbid all but a few from ever becoming
deep-sea treasure hunters.

Now, however, every owner of a CoCo can become an
underwater treasure hunter without ever donning a wetsuit.
With the introduction of Sea Quest, a 32K Extended Color
BASIC graphic Adventure, the armchair Adventurer can
comb the beaches, explore the hurricane-sacked houses, and
scour the ocean floor in search of clues to treasures that
would ransom a king.

As in most Adventures, the object of the game is to find
several treasures — in this case five — and return with them
to a central location. Now, this is not the toughest Adven-
ture Pvc ever embarked upon, but it's guaranteed to occupy
several hours. To dale, Tve managed to find four of the
treasures, but the fifth eludes me completely; I haven't a
clue. IVc been aggravated, puzzled, perplexed and dis-
gusted, which, as bad as it sounds, is exactly what puzzle
solving is all about. It's the quest, the mental stimulation and
the sweet taste of victory that make all the aggravation
worthwhile.

Besides, in this particular game 1 was surprised to meet up
with this knife-brandishing character that, each time 1 tried
to pass him, kept saying, "Dis be my island, mate, and 1
don't be liking strangers." I would almost swear that I ran
into this guy in Miami one summer.

Both the cassette and disk versions of Sea Quest come in
stylish packages with short, but ample, documentation
printed on the backs of the packages. After all, you don't
need a textbook accompanying an Adventure that even
EXECutes automatically. The thrill of these games is in
discovering what works not being told. Right?

But, after all else has been said, it's the graphic screens
that are the shining stars of this game. They're some of the
best that I've seen. The fantastic strides that have been made
in this genre of games in such a short time display clearly
that their potential is only now beginning to be realized —
potential limited only by the imaginations of the pro-
grammers. What's more, Mark Data appears to be on the
cutting edge of the new graphic Adventure technologies. I've
spent some time scratching my head over each of their
releases, and I've been more than impressed with them all.

All things considered, you simply can't go wrong with Sea
Quest. The worst thing that I could say about it is that I'm
going crazy trying to find that last treasure. As for the price
of $24.95 lor cassette and $27.95 lor disk, 1 figure that the
time I've spent playing the game converts to around $3 an
hour and I'm by no means finished solving it yet.

If only all of life's little pleasures were as cheap!

Speed Reading
The Fast, Fun Way

Speed Reading by B & B Software, consists of six text
programs. Side one includes /4 Service of Love by Henry,
The Adventures of Hercules, and Life on the Mississippi by
Mark Twain. Side two has ne Teii-Taie Heart by Edgar
Allen Poe, Hamlet, Prince of Denmark by William Shakes-
peare, and The Hollow of the Three Hills by Nathaniel
Hawthorne. At the beginning of each side of the tape is a
number drill which is designed to improve peripheral vision,
a necessary skill for speed reading.

Speed Reading was written for either 16K BASIC or 16K
Extended BASIC. However, in the latter case a POKE
25,6:NEWis required.

After the user RUNs one of the text programs, he is asked
to choose a reading speed. The parameters are between 100
and 3000 words per minute. The documentation states that
the average reading speed is 250 words per minute and I
found this a good place to start. The user is then asked to
/NPUTa starting page. Each page is a text screen, 13 screen
lines in length. The stories range from 27 to 36 pages long.
The user can start reading at any point in the story. If he
enters a page number that is past the end of the story, the
text begins with Page 1.

If, while reading a story, the user finds the text too slow,
he can speed it up by keying [F]. This will increase the speed
by five percent. Conversely, if the speed is too fast, it can be
slowed down by keying [S] and this will decrease the speed
by five percent. This can be done as many times as the reader
finds necessary. B & B recommends choosing a speed that is
faster than you can comfortably read.

When you wish to stop, depress [E] and the screen will
clear. The program will then display the final reading speed.

It is necessary to understand that this is a training pro-
gram. We all know that "practice makes perfect."

There is no testing at the end of the text, and the reader
should be careful to monitor his comprehension as he pro-
gresses. If the story doesn't make sense, he needs to slow
down.

This is not a program for young children. The stories arc
quite involved and very different writing styles are employed.
I would estimate that a person should be at least in junior
high school in order to use these programs effectively. How-
ever, the text is brought to the screen through use of DA TA
statements and the user could include new .stories by doing a
lot of typing and changing the DA TA statements. Although
a fair knowledge of programming is necessary, this makes
the scop
