WHICH WAY TO SPEED?
Editor:
In your September 1983 issue on page 234
you stated that POKE 65495.0 can speed
things up but the operator cannot use I/O
operations (CLOAD. CSA VE, etc.).
However, on page 6 in the same issue you
printed a letter from Anthony Graves, with
good instructions for using various POKEi
to accomplish the I/O operations while in
the high speed mode.
Who is correct?
Max M. James
Lebanon, IL
Editor's Note: POKE 65495,0 can be
used to speed up the CPU before tape
I/O but the tapes will not be at a
standard Baud rate.
IT'S TERMINAL
Editor:
Is there any way to hook a Color Compu-
ter directly to a R.S. Model I II? (For things
like common programs— loading and down-
loading, etc.?)
Mark Rogstad
Yakima, WA
Editor's Note: One method of com-
munication is by use of a terminal
program in both computers using the
RS-232 ports. Another method is by
using (111 by Computer Shack to
directly transfer disk flies.
HINTS 1H* TIPS
Editor:
In the September issue of the Rainbow.
you published a program entitled Biblio-
graphy File. I typed in the program, but was
unable to get the title search routine to print
to the screen or my printer. I added the
following line, and the routine functioned
perfectly:
3445 1FLEN(TE$K32 THENTE$=TE$+
STRING$(32-LEN(TE$),32)
The problem occurred because the pro-
gram stores the book titles in left justified.
blank filled. 80-character strings. Unless the
search string is also blank filled, the program
won't be able to locate any titles.
I love your magazine. It is the only one I
buy for the CoCo, and it is more than
enough. Keep up the good work!
Howard Hartsfield

Editor:
In the June 1983 issue of Rainbow on page
68 there is a small program called Disk Dis-
play. 1 found one very good use for it; I
examined the sectors of Adventure games
such as Sands of Egypt by Radio Shack,
which as you know, docs not contain the
commands you need to use. By searching
through the sectors, the commands will
become present. This program gave me
some help in finishing Sands of Egypt.

games: Calixto Island. Black Sanctum.
Raakatu. Pyramid. Bedlam, Madness And

HIDDEN HINTS
Editor:
Reading Tom Szlucha's article on the
hidden commands of the MC- 10 (September
1983). I thought it might be of interest to
your readers to have the following infor-
mation:
USR vector: Store 16-bit addrcssat S42I6
(16918) Keyboard input character: use
JSR SF865 (returns in ACCA) Output
character to screen: Load ACCA with
ASCII, use JSR SF9C6
I have not figured out the parameter pass-
ing for USR yet, but this works well to
transfer control to an assembly language
routine. There is a J M P instruction at S42 15.
followed by a 16-bit address that is the user
vector. This points to an error message dur-
ing system initialization. Incidentally, in-
spection of the ROM at address SE000
(57344) will reveal a list of 16-bit addresses,
followed by the actual commands (ASCII),
followed by more addresses. The USR func-
tion is the third entry in the vector table
(SE006).
There is a jump table in RAM around
S42 1 5 that has the user adjustable vectors for
all the interrupts in the system, including
SW1. These can be very useful for figuring
out how the MC-10 works.
A couple more key addresses: the MC6847
video controller is located at SA000 (40960).
You can make all kinds of neat sounds by
flipping bit 7 of SA000 up and down (this is
"connected" to the speaker). Be careful not
to change the other 7 bits of SA000 as these
are the control bits for the 6847! Also, the
"powered up" byte in the MC-10 is located at
location SEA (234). On reset, the MC-10
looks in SEA to see if it contains a S55 (85). If
not, it reloads all defaults and clears any
program that might have been in the unit. If
S55 is found there. itdoesa"warm"startand
simply clears the screen and prints OK. I'm
sure it also reinitializes the system I/O on
either type of reset.
Hope this information is helpful.

Editor:
I have found out how to start on higher
levels in Donkev King. To do this you must
POKE 12889,10 to start on the rivets level,
POKE 12889,2 to start on the elevator level,
or POKE 12889,18 lo start on the conveyor
belts. All of these are on a high skill level. If
you would like to experiment with this you
can also change 12889 to other numbers
each of which will have some effect on the
game. I would also like to say that I believe
the Rainbow is the best magazine for the
CoCo, Keep up the good work.
Robert Williams
Moore, OK
Editor:
In the August Stained Glass article. Wes
Fauske asked why his "SG24" mode used
only 3K instead of 6K of memory.
When he set up his graphics he got into the
G1C mode instead of the SC24 mode. SC24
uses 6K and G IC uses I K of memory.
By not setting the "Video Control Regis-
ter," Wes did not get a true G1C but got
caught between G I C and the "TEXT" mode.
Change the last number in line 25 of his
program from 128 to anything between 65
and 90. The screen will be filled with 512
TEXT letters between A and Z. You may
poke address 13019 with these values if you
saved the program in machine code.

WHY NOT SAVE/LOAD?
Editor:
I am writing about Dan Downard's Ram-
bug Monitor. 1 have a suggestion for him. 1
would like to SEC disk save/ load machine
language programs. There is disk memory
examine/ change, so why not save/ load?
How about a disassembler, too?
Andy Janjigian
Editor's Note: Wesiwood. MA
Disk BASIC stores programs at a
higher location in memory than
Extended BASIC. Sometimes
memory conflicts occur. A solution
is to make the machine language
program reside at the top of
memory. Software author's for
Rainbow are encouraged to write
the ML portion of the program in
PIC (position independent code)
and also locate the program near
the top of memory so that it can be
protected by a CLEAR command.
MULTILINGUAL COCO?
Editor:
When 1 was reading the September 1983
Rainbow edition, I saw one article that
really made me wonder. The article was
about the new CoCo and its special OS-9.
I was wondering if 1 could get the OS-9
and the thing that lets me use different lan-
guages for my old CoCo. My computer sys-
tem consists of a 64K CoCo. one DOS 1,0.
one cassette, and an Okidata 82A printer.
Denny Reinhardt
Orofmo, ID
Editor's Note: OS-9 will operate on
any 64K CoCo and it is the system
that allows higher level languages.
FELLOW NEWSLETTER
Editor:
As I read through your magazine, which I
happen to enjoy very much, I often stumble
onto the fact that the Rainbow magazine
started as a two-paged photocopied newslet-
ter. I am sure that a few years ago you never
dreamt of a three-hundred page fully public-
ized major magazine. I commend and com-
pliment your magazine but 1 also would like
to ask for help. I am starting a newsletter and
I have not had much luck in syndicating it. i
feel it is a good little newsletter (only a few
pages) and I think it could do well for other
people such as column writers, unsung game
programmers and columnists. I ask you to
print this letter so people will send in their
contributions of these items. If successful. I
would like these people to write for my new-
sletter permanently and maybe someday it
will turn into a real magazine. If you would
ju. t send a self-addressed envelope (to 8
Paprota Cl. Parlin, NJ 08859). you will
receive our first newsletter with your articles
and submissions. I love to write and I love
my Color Computer and wish you people
would send your submissions. The small
businessman is welcomed and for you who
would like to advertise and have a program
to sell, please write me. I can't describe the
willpower and earnest of our staff (only 12)
but we have had no luck reaching people
who would like to contribute.

I just received my September issue of
Rainbow in the mail. I'm just "itching" to
read the darn thine: but, I had to write this
Thank You note, first.
After my notification that I had not
received the issue, you sent the issue priority
mail to me! Fantastic!
This example of customer interest is exact-
ly why the Rainbow is the number one CoCo
magazine!

Well, it has been two great years since I
bought my CoCo, and with the great articles
in your magazine 1 have improved my origi-
nal 4K to 32K and have a new keyboard.
I think you have the best magazine in the
world, without a doubt.
George Kaakee
Royal Oak. Ml
Editor:
I would like to comment on your maga-
zine. It is the best magazine for the CoCo
around. No other magazine has the great
graphic programs that you do. Since I've
been buying your magazine, 1 feel the pro-
gram called Roach is my favorite. Whenever
people come over, they ask to play the game.
Sometimes 1 wonder if they come over to see
me, or to play the game. Keep up the fantas-
tic job. and I'm looking forward to more
great programs!

THE BEST DOWN UNDER
Editor:
1 suppose there can never be such a thing
as an overload of genuine praise. Therefore,
1 send my compliments to both you and
our magazine. Today, out of curiosity, I
purchased some other Color Computer mag-
azines from a Sydney newsstand . . . there is
no comparison with the Rainbow!

LEARNING BY R.O.T.
Editor:
Rainbow On Tape is a "good buy," but the
teaching advantage is what I find to be the
most advantageous. I read almost all the
articles in all of the computer magazines. Or
that is, the CoCo computer magazines. In
doing this. I have not had a lot of time left
over to type in printed programs — espe-
cially the ones that are more in the "learn-
ing" category. However, as I have all of the
Rainbow programs on tape, I can RUN
every program. That way I can learn the
lesson that is presented and also see the pro-
gram in operation.
Please do make every effort that you can
to get the most — no all — of your readers
subscribing to Rainbow On Tape.

A COCO MATE
Editor:
In response to William Burns'query in the
September Rainbow, the Manncsmann Tal-
ly MT 1 60 printer is an excellent mate for the
CoCo. It interfaces directly (I run at 2400
Baud). With its multitude of features, includ-
ing graphics, EPSON and Daisy Wheel code
support, large buffer, proportional spacing,
etc., it's a dream. Any CoCo owner needing
cable fabrication or setup information can

My husband and I think your magazine is
the greatest! There are just so many helpful
articles in it.
We have a Radio Shack TRS-80 CoCo

ble with the Raaka-Tu game. We can get all
of the way through up until we get to the
rectangular room with the carpet over the
pit. You cannot jump over it and there is no
room to go around but you need to get to the
door on the other side. Wc would appreciate
it very much if any of your readers have a
solution. Please send answers to: 4 14 1 Ham-

1 purchased the C. Itok Prowriter 8510
printer a couple of months ago. It's a great
printer when interfaced to the Color Com-
puter with the BOTEK Parallel Printer
Interface. I just POKE 150.1 to set the com-
puter Baud rate to 9600 and set the Baud rate
switch to the same setting. This combination
works like a charm. This great printer should
be looked at by anyone in the market for a
new printer. I highly recommend it.
I would like to know if anvonc knows of a
screen dump program that works with this
printer the 85 10 uses different control codes
than the Radio Shack printers, so the screen
dump that they use doesn't work at all.
I've been with you since Feb. "82, and have
watched you grow from 3 1 pages to over
300. 1 look forward to each exciting issue in
my mailbox each month. Keep up the good
work.

which 1 use a tape recorder with. I just pur-
chased a DMP-120 printer from Radio
Shack. I would like to know how I can print
a certain number of lines so when 1 use fan
fold paper and come to the end of the paper.
1 can't have half a line on one sheet and the
other half on the next sheet? Is there a state-
ment I can type in that skips so many lines
and types so many and so forth? Thank you.

Editor:
I have Telewriter-64 and get tired of enter-
ing the same formatting information each
time I want to print something. I have added
the needed POKE 150.1 to line and the
appropriate POKE from page 33 of the
Telewriter-64 Reference Manual to line 210
of"U"to eliminate the sparkle but this is as
far as 1 have been able to get.
A letter to Cognitec was of no help. Is
there anyone out there who can figure out
how to change the other default format
numbers? As I told Cognitec. "1 don't wish
to meddle with a well-programmed piece of
software but not having to do an operation
(the same way) every time I wish to print
something seems a legitimate reason to
change."

"admit I realize that some of you will be reading this somewhat
late to do much about it, but just in case you are not, there is
-still time to make RAINBOWfest in Fort Worth Oct. 14-16.
1 think that this is going to be one truly great show! And, perhaps
more important, we have gotten the word that there will be tours of
the Tandy CoCo manufacturing plant during the RAINBOWfest. If
you want to see how, and where, CoCo is "born," so to speak,
RAINBOWfest in Fort Worth is the place to be!
The tour will be at "cost" — just what it will cost to rent the buses
to take us from the Hyatt-Regency Fort Worth to the plant, a total of
$3 per person. But the space is limited. So, if you wanted to make it to
RAINBOWfest but needed a reason until now — this is a great one.
I'm pleased, too, that we have what 1 consider to be an outstanding
lineup of people for seminars at RAINBOWfest. Tops on the list is
Mark Yamagata, the new Director for Computer Merchandising
— Personal Computer Products at Radio Shack. Mark has just been
appointed to his new post and this will be one of the first public
. ( appearances he will be making. We feel especially honored that he is
'J choosing to keynote our "CoCo Community" Breakfast. Be sure to
put the breakfast Saturday morning on your RAINBOWfest agenda.
Mark is not the only "name" we will be having. Some of the CoCo world's most popular programmers will
be on hand; as will a number of our Rainbow columnists. We think that RAINBOWfest will be not only an
excellent exposition, but an outstanding opportunity to learn, too. With people like Don Inman, John
Gabbard and Steve Blyn there, how can you miss out?
And, in case you missed the notice in the advertisement, we've been fortunate enough to set our keynote
speaker for the second RAINBOWfest of the season, at Long Beach, Calif., in February. Bob Albrecht, the
reknowned columnist and author, will keynote thai "CoCo Community" Breakfast.
By the way, someone asked me the other day why we're having four R AIN BOWfests this year, f he answer
is a simple one: We'd like to have the shows in locations that will be relatively easy for you to travel to. One
of the things which impressed me about the first show last year in Chicago was the long distances some of the
RAINBOWfest -goers came to attend. Thus, 1 suppose, was born the concept of "regional shows." Make no
mistake about it, having four RAINBOWfests is far more costly, in terms of both time and money, than just
one or two. But our aim, overall, is to make it as easy as possible for the most number of people to participate
as possible.
No, I'm not saying we're doing this just out of the goodness of our hearts. But I am saying that, frankly, we
will make less money by doing four shows than by doing just one or two. Still, we should do better than break
even, and we do want to "spread the word "a bout CoCo as widely as we can; making it possible for as many to
attend as inexpensively as they can. Thus, regional RAINBOWfests.
I'm especially pleased with some of the longer programs in this month's issue and, although I usually let
Managing Editor Jim Reed write about the contents of a particular issue, I'd like to "brag" on these special
ones.
As most followers of the Rainbow probably know by now, one of the abiding interests we have had has
been in data communications. And so, this is our Data Communications Issue. That, in and of itself, is
something important, but what's more important is the fact that we wanted to do something special for this
special subject.
Rainhoard was the answer to this special need. It comes from the talented Dr. Lane Lester who has, over
the past couple of years, made a number of significant contributions to the Rainbow. None of them is more
significant than is this program, which, I feel sure, will open up a whole range of communications possibilities
to thousands of you.
While expensive from the standpoint of telephone calls over long distances, communicating with local
bulletin boards is a way for CoCoists to easily ban together. Imagine! Now, in any local telephone calling area
where there is more one Color Computer, a person has the means to communicate without missing messages
and through the ease that a computer can bring. Maybe, just maybe, we should have saved Lane's program
until the January issue, called that one the "George Orwell Issue"and presented Rainboard — something that
is truly 1984-ish.
If data communications bore you, though, just consider this one: You can easily run Rainboard in your
own home and use it as a means to leave messages and the like with other members of your family. You don't
even need a modem to do that. Lane, thanks for a fine program that I am sure will have many singing your
praises.
The other two special programs are our two Simulation Contest winners. What could be more appropriate
heading into a presidential election year than Election 84? And, although the judging was completed before
Korean Air Lines Flight 007 was shot down by the Russians, what could be more timely than WarGamel It is.
November 1983 the RAINBOW 13
indeed, sad that we must live in a time when a nation can so
calmly slaughter innocent men. women and children as the
Russians did last month.
Special best wishes to our two winners. One will receive an
Epson FX-80 printer and 4K buffer from JARB Software
and the other, a Disk Drive and controller from us. Other
winners get prizes from Spectrum Projects, Custom Soft-
ware Engineering, Computer Island, Tom Mix Software
and Classical Computing.
And, our thanks to the many who contributed to our
Simulation Contest. There will be another, after the second
running of our Adventure Contest, which begins with this
issue.
And, on to the rules of the Adventure Contest itself. You
must submit an original Adventure program and certify to
us that it is your own, original work. The program should be
on tape or disk and can be either a graphics or a non-
graphics game.
All entries become the property of Falsoft, Inc., and none
can be returned. Deadline for submissions to the contest is
March 1, 1984. Winners will be announced in our special
Adventure issue. As usual, there will be a list of top prizes.
Duplicate prizes to be awarded in case of ties.
Please include full documentation, along with the solu-
tion to the Adventure. Entries should be addressed to
Adventure Contest Editor, Rainbow Magazine, P.O. Box
209, Prospect. KY 40059. Last year's contest was just super
and we expect this year's to be even bigger and better. Watch
future issues of the Rainbow for a full list of prizes.
I received a letter from one of our readers the other day,
asking whether we could show photographs of our office.
The writer expressed interest in seeing what our "office"
looked like.
I'd like to know what it looks like, too. As many of you are
probably aware, we have been expanding rapidly for some
time. So, the reason / wonder what things look like is
because between the people, furniture and computers, it is
almost impossible to see the "office" itself. We began on
our kitchen table, moved to 1200 square feet of renovated
basement and then to 2000 square feet of office space in the
Prospect Point Shopping Center nine months ago. We
choose the particular location that we are now in because it
was right next door to the Post Office and because of an
interest in helping us on the part of both the real estate
manager for the complex and the people who own it. When
things began to get crowded (about the day after we moved

in, it seemed), we wondered where we might grow into next.
Happily, as you read this, the problem has been solved.
We now occupy both sides of the Post Office and have an
additional 2850 square feet from which to continue to bring
you the Rainbow (and PCM — 77k? Portable Computing
Magazine) each month.
Splitting up means we had to split something up, of
course. So, we "left" our editorial and design staffs in the old
space and moved Customer Service, Accounting, Rainbow
On Tape, Advertising, Shipping and our other "business"
departments to the new location. For the first time, editorial
and design finally have room to do all the things they need
to, and the business side has enough space to really operate
and file things.
One of the things which has made this all possible is, as
usual. Radio Shack. Basing things on the excellent success
we've had with their computers (the "business" part of the
business is all on Radio Shack computers, too, and yes, we
do all the subscription servicing and so on ourselves), we
opted for a Radio Shack telephone system. Thanks to the
expertise of a great many people, we may be in two separate
offices, but we're tied together by one phone system where
— if necessary — everyone can talk to everyone else. We can
conference calls, use speed dialing and so many other things
this column might begin to sound like an ad written in
Tandy Center if we kept on. We won't. But, //you do have
occasion to call us, you'll be in good hands!
No, our telephone number will not change, nor, for all
practical purposes will our address. An added convenience
for callers is that we have almost doubled the number of
telephone lines we had previously, so there won't be as many
busy signals.
If you get the idea we're proud of our new offices, you're
right. And, by the way, we welcome visitors. So. if you are
ever in the Louisville area, please stop by. We'd like to see
you in person.
As you know, we're about a month ahead on these
columns and each issue of the Rainbow. So, we have not put
it all together yet, but please be aware that, as I mentioned
last month, we will have a subscription price increase. It will
most likely be effective January 1, 1984. As we did so a year
ago, we offer all present subscribers an opportunity to
extend their subscriptions at the present rate ($22 in the
United States. U.S. $29 in Canada and Mexico, and U.S.
$57 surface to other countries, U.S. $85 air mail to other
countries). Right now. we're working with our printer to see
what it will cost to publish next year and expect to formally
announce our rate increase next month. Meantime, if you
would like to extend your subscription by one year at the old
rate, now is the time to do so.
While on the subject of subscriptions, let me point out
that we do have some very nice gift certificates available for
holiday giving. Just ask that a gift subscription be sent when
you write.
And, this was mentioned to me some time ago as a sugges-
tion: A really nice gift you can give for all of the next year is a
subscription to the Rainbow to your local school or library.
Not only is it a way to help your school or library, but the
subscription cost is tax deductable as a charitable contribu-
tion. It would be a nice present, and may help someone get
started in computers the right way — with a CoCo!

THK ORIGINAL
Simply slated. Telewriter is the most powerful
word processor you can buy for the TRS-80
Color Computer. The original Telewriter has
received rave reviews in every major Color
Computer and TRS-80 magazine, as well as
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.
Telewriter gives the Color Computer a 51
column by 24 line screen display with true
lower case characters. So a Telewriter screen
looks like a printed page, with a good chunk of
text on screen at one time. In fact, more on
screen text than you'd get with Apple II, Atari,
Tl. 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, Telewriter 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...
— Color Computer News, Jan. 1982
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
don't 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 layout of
your printed page, all on the screen at one
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 of 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:

BUILDING NOVEMBERS RAINBOW
Our Data Communications issue . . .
Introducing the Rainboard BBS . . .
And, our Simulation Contest Winners . .
We get far more mail here at the Rainbow than at any other publication I've
been associated with. And, while only a small portion makes it into the Letters to
the Editor, or the new letters sections in both the CoCo Clubs section and the
new Reviews section, we do take our readers' criticisms, suggestions and obser-
vations to heart. One reader from North Carolina recently sent in his personal
list of concerns, closing with: "Keep On Keepin' On, But Do It Better! And
Hurry The Process!!"
Well, W.J.F., we're trying to do just that and, yes, we have modified Rainbow
On Tape so that you no longer have to turn off the machine after running the
menu. That was an oversight on our part and we appreciate your calling it to our
attention. Similarly, your other concerns and those expressed by other readers
are being attended to as quickly as we can do so, but do have patience because we
have a long lead time and thoughts expressed today may require months to
implement.
This month we focus on data communication, computer-to-computer com-
munication, a concept that sounds speedy, but can be painfully slow at 300
Baud. Still, the mostly untapped potential of data communication is fascinating.
For instance, with Rainbow Technical Editor Dan Downard's Remote, a
machine language driver program, you'll be able to run your CoCo by remote
control. With our list of computer Bulletin Board Systems, you'll be able to
"talk" to other computer users anytime night or day. With Alan Davenport's
Master Messenger, you'll be able to format "E-Mail" before you even log on
services such as The Source and CompuServe. And, as our special feature this
month, we have Rainboard!
Rainboard is a complete BBS, or Bulletin Board System, that our favorite
biologist. Dr. Lane Lester, has designed to work on a single disk drive with an
"intelligent" modem. And it's yours to have and to use for the price of this issue.
Now, the chance to be a "SYSOP"is within range of thousands of us. Just boot it
up and wait for the calls to come in. Ma Bell should pay us a royalty for the
increased business we predict this will generate. Rainboard 'isn't The Source, but
it is user modifiable and can be your source for lots of fun and new-found
friends. Enjoy!
As always, we have a diverse mix of articles and programs in addition to our
data communications theme. These range from a lesson in "disk washing" —
don't take that too literally — and disk calibration to the "glowing" love story of
"The Laserworm and The Firefly." Paul Hoffman has another X-Pad feature
and Tommy and Gail Pollock offer a musical "Bach to BASIC."
Finally, of the several prize-winning entries in our Simulation Contest, our
two top awards go to Bob Tyson for Election %4 and to Tom Weber for
WarGame. Both Simulations are exceptional, in length and in reward, as well as
in timeliness and playability, so don't miss them. No, you don't have to run for
President before playing WarGame. Simulation Contest Chief Judge Charles
Springer offers an overview of the contest and reveals all the other winners, too,
in his judges' report.
So, we keep on keeping on, with an eye to doing it better and a pledge to hurry
the process. You keep the letters coming and we'll respond monthly with a
Rainbow that weighs well over a pound. A full year's subscription is still just $22,
less than half the cover price. We do get a lot of mail, but we want even more.
That's why we, having just expanded again, now occupy office space on both
sides of the local post office.

THE TOP-RATED COCO WORD PROCESSOR:
Coiorware researched the word
processors available (or the Color
Computer. We came to the very
same conclusion that so many re-
view articles have! Telewriter-64
is, by far, the superior word pro-
cessor for the Color Computer.
Why is Telewriter so much bet-
ter than the others? For one thing,
it has overcome the 32x1 6 charac-
ter display limitation ot the Color
Computer. No small feat, Telewri-
ter accomplishes this by generat-
ing its own set of characters in
software. You select 51x24, 64x24
or 85x24 character displays by
merely issuing a format command.
If you have ever used a word pro-
cessing system, you know how im-
portant it is to be able to see a good
portion of your text on the screen.
TELEWRITER-64
Telewriter-64 also generates
true lower case characters. This is
much preferable to the reverse
characters that merely "represent"
lower case letters in other co-co
word processors.
Telewriter-64 is feature packed.
Besides the standard features
found in any word processor. Tele-
writer also includes: user-friendly
full-screen editing, rapid cursor
and scrolling control, page jump,
right justification, menu-driven
disk or cassette access, compata-
billty with spelling checkers (such
as Spell-and-Fix), and a clever
double check that asks the user
"Are you sure?" before executing
any operation that would kill any
sizeable amount of your text.
Telewriter-64 runs on any 16K,
32K, or 64K system (extended
Basic not required) and works with
any printer. It has all of the control
codes necessary to take full ad-
vantage of all of the features in any

RAINBOW
j- -y
Have you bought your CoCo a modem yet? Have you
sampled the joys (and the telephone bills) of roam-
ing through the Network Nation? All over the coun-
try there are BBS's (bulletin board systems), computers
waiting to take your call, systems dedicated to the interests
of Color Computer owners. Here in the small town of
Lynchburg, Va., there are very few Color users as dedicated
(euphemism for "freaked out") as 1, and communications
capability allows me to reach out with telephone tentacles to
like-minded individuals around the country. Some of my
most valuable exchanges of information have come from
Kent Meyers in LeRoy, Minn., by way of the Color Connec-
tion in Elgin, Texas. ( By the way, Kent has supplied much of
the information appearing in the Rainbow 's listing of BBS's
elsewhere in this issue.) In addition to your modem, you'll
also need a terminal program, several of which have been
reviewed in the Rainbow.
But this article is really aimed at those who have already
come to appreciate both the enjoyment and edification that
comes from communicating with other Color users via the
bulletin board systems supporting our machine. To many of
us, the SYSOP (System Operator, manager of the bulletin
board) is a godlike creature, sitting like a spider in the
middle of its web. The mighty SYSOP receives our trans-
missions from everywhere, answering our questions, and
controlling what messages, files, and programs are available
to us lower sorts. The aspiration to be like God led to Satan's
downfall and many of us have lusted in our hearts to be a
SYSOP, with all the adoration and power that accompanies
that position.
I must confess to you that 1 have long had a secret desire to
operate my own BBS. Of course, one very serious hindrance
to such a project is that while the computer is running the
board it can't do anything else. For the most part, only those
who have an extra computer to spare can be a SYSOP. One
day it occurred to me that since the CoCo in my office at
school is alone all night long, it could run a BBS at night!
Then I looked at the prices of bulletin board software,
almost all in the neighborhood of S 100 an up. Another blow
to my ambition. One day 1 purchased for SI 9.95 a very
interesting machine language program, RemoTerm by Star-
Kits. I could load and execute this program in my office
CoCo, go home and use my home CoCo by telephone to
load and run programs in my office. It occurred to me that I
could use RemoTerm to ran a BBS; all 1 had to do was write
a BASIC program to manage the system.
RainBoard, "With a Rainbow of Colorand a Pot of Gold
in Good Times," is now a reality, and I'm having a great
time. Perhaps you would enjoy operating your own board;
the following programs will allow you to find out without a
great expenditure in cash, only in time. As faras hardware is
concerned you'll need a 32K CoCo with Disk BASIC, one
disk drive, and an auto-answer modem. A price break-
through for this last item came with the development of the
Novation J-CAT, which is discounted for a little over $100.
But as important as is the right hardware, it's the software
that makes a BBS the special thing it is, so the rest of this
(Lane Lester is professor of biology at Liberty Baptist
College and holds the M. S. in ecology and the Ph. D. in

article will be devoted to describing the use of the programs
that follow.
There are four programs accompanying this article which
are included on Rainbow on Tape. Remote is the BASIC
program that I run just before I go home each evening. It
first loads RemoTerm, and then changes it to disable the
callers' [BREAK] key. The modified RemoTerm is exe-
cuted, and finally RAINBORD the BBS program, is run.
This version of REMOTEalso sets some parameters on my
Hayes Smart Modem, and would have to be changed if you
have a different unit. A timer turns off the system at mid-
night and then turns it on at 7:30 a.m.. so that it's warm and
waiting when I get to the office. S YSOP is the first program I
run, displaying the activity on the RainBoard the previous
night. It has some other functions that are self-explanatory
and aid in the maintenance of the board. GRAFMESS,
which I downloaded from the Color Connection and modi-
fied considerably, allows me to create the color graphics
screens that I believe add a nice touch to the Rainboard.
RAINBORD supports the following BBS functions:
Help with BBS functions.
Bulletins of interest to callers.
Scan message subjects for possible retrieval.
Read messages.
Leave messages.
Programs available for downloading.
Text files on various subjects.
Art gallery of graphics
Member list
Goodbye — leaves the RainBoard ready for the next
caller.
Perhaps the most logical way to describe the use of
RAINBORD is to relate my comments to particular sec-
tions of the program. Line numbers will be shown in paren-
theses. This should both help you see what's going on and
aid you in customizing it for your own use. An immediate
jump (20) to the bottom of the program avoids the notorious
PCLEAR bug. The Lower/ Upper Case Input Routine (3) is
called at various times in the program and allows the caller
to use either lower or upper case responses to prompts.
Single letter responses produce a colored stripe across the
screen which provides part of the Rain Board's promise of "a
rainbow of color." Three arrays are dimensioned (70), DIS-
PLAYS (for graphics, 15/picture), NAMES (BBS mem-
bers), and TEXTS (for message entry). Next (80) I load the
three graphic screens that I'm currently using which were
created with the graphics message program GRAFMESS.
The first two are displayed in lines 150 and 390, respectively,
and the third is in the Art Gallery ( 1 220). If you add pictures
to the Art Gallery, you'll need to change in line 1240 the
number 45 to 15 more for each picture. The list of current
members of the BBS is then loaded ( 100). Because the gra-
phics and member list arc displayed often, they are kept in
RAM to minimize disk use. The disk file of members is,
however, updated whenever a new member joins the board.
RAINBORD refers to disk drives either by default or as
D 1 . By making all of them 0(110) only one drive is required,
and the only limitation is on the number of text, program,
and message files that can be online. Once way to maximize
November 1983 Ihe RAINBOW 21
space is to keep the four BBS programs RAINBORD.
REMOTE, SYSOP, and GRAFMESS plus the graphics
files WELCOME, HELP, and those in the Art Gallery on
one disk which is only used at the time the Rain Board is
started. All other files can be on a second disk which stays in
the drive as long as the BBS is online. Text files always go on
the default drive (0), but because I am blessed with a Radio
Shack drive and a double-sided MPI drive wired as drives
1 and 2, my own version of line 110 reads: Dl = l:
1$="1":D2=2:D2$="2."
When someone calls the RainBoard, program line 130 is
waiting for a carriage return [ENTER]. The caller is given a
chance ( 140) to request 7 or 8 bits , which will determine at
various places in the program whether text or graphics will
be displayed. For callers who are using the smart terminal
program Co/orCom/£theCHR$(27)"G4"sets the program
to 8 bits. To speed logging on, the caller is asked for initials
only (170) which are checked against the member list (190)
and if a match is found, the caller is asked for verification
(200). November callers go through the "New Member Sig-
nup" section (220-340), while for members the message files
are checked and any new messages addressed to the caller
displayed.
You'll notice throughout the program that a string,
ACTS, is constantly growing. This is the record of the
caller's ACTivity which is recorded when the caller logs off.
FL is another variable whose purpose may not be imme-
diately obvious. It serves as a FLag to allow the program to
hang up on at least some mischief-makers. CHRS( 1 3) is used
where commas would ordinarily do so that callers with other

than 32-character displays will see a decent screen. The last
step in new member signup is the display of the text file
"NEWMEMBER" (340) which provides information for
beginners.
The Main Menu (350) consists of only a single line to
speed communication. If a person responds with an invalid
character, an "H," or simply a carriage return [ENTER], an
expanded menu is displayed (380-440). After they are
selected, most of the individual functions have available
complete help files on the disk. As each function is selected,
the GOSUB1300 keeps track of both the type and amount of
the caller's activity.
The "Scan Messages" function (480-560) next needs
comment. Each message occupies a separate granule on the
disk, and the scan function displays both the filename and
extension. Filenames indicate the subject of the message and
extensions the initials of the intended recepient. Messages to
"A 1 1 " have extensions such as " A09" to indicate the month
entered. The caller can request Help, a Complete scan,
Initials to scan, or Return to Main Menu.
The "Read Messages" function (570-720) offers similar
options with the ability to retrieve selected Subjects or
Initials. A directory search subroutine (640-710) serves all
options as well as the initial message search when a member
first calls the Rainboard. The ability to create private mes-
sages is provided when the subject specified is "PER-
SONAL" so that only the intended recipient can retrieve
them (670). When a caller reads one of his or her messages,
an asterisk replaces the middle initial in the file extension
(690), making possible the display of only new message
while leaving old ones for others to read. An opportunity to
reply is immediately provided the recipient (700).
The caller's options in the "Leave Messages" function are
different in that three letters are expected (740). A lengthy
series of checks and prompts insure that only valid disk file
specifications are given by the caller, and that duplicate
filenames do not erase other messages. Because most CoCo
terminal programs have word-wrap prevention, a 63-charac-
ter line length for those who print their messages after going
offline. A "." printed above each line helps the caller keep
track of the line length, but if he or she exceeds 63 characters
an error message is displayed and the line truncated to the
proper length (900-910).
The remaining functions do not require much comment.
For both BASIC programs to download and text files to read,
the caller can get a List or Descriptions (950 and 1090). The
Art Gallery ( 1 220) is a nice idea that 1 lack the artistic talent
to fully exploit. The Goodbye function writes the caller's
activity to a file ( 1 280), says a personal goodbye ( 1 290), and
hangs up the Smart Modem (1300-1320) before jumping
back to the beginning for the next caller. If you use the
Novation J— CAT. you can delete lines 1300-1301; it will
hang up after the caller.
The Display File routine (1330) is called whenever an
ASCII file of any type is to be transmitted to the caller. This
includes messages, text files, and programs. The Activity
Length Test (1360) keeps track of each caller's use of the
Rainboard and helps to prevent someone's monopolizing
the system. If a caller is having trouble using the BBS, you
can usually see what's wrong when you display the activity
file using the program SYSOP. Several places in RAIN-
BORD the membership list is checked (1400), and each
graphic screen created by GRA FMESS is loaded by the last
routine (1420). In line 80. the values of Y and Z determine
the location of each graphic in the single array.

Rainboard Procedures
The following is a step-by-step list of things to do to get
the Rainboard up and running:
1. Use DSK1NI0 to erase and format two disks. We'll call
them Disk 1 and Disk 2 in the following steps.
2. Put on Disk 1 the four BASIC programs REMOTE,
RAINBORD, SYSOP. andGRAFMESS. You can either
type them in from the magazine, get them on Rainbow on
Tape, or best of all. send me $20 for a disk also containing
supporting text and graphics files. Also SA VEM to this disk
either Remo Term or the machine language program written
by Rainbow Technical Editor Dan Downard and appearing
elsewhere in this issue. Edit REMOTE to contain the name
of the program you decide to use.
3. Run GRA FMESS (described below) and create the gra-
phic files WELCOME. HELP, and any that you would like
to display in the Art Gallery. Save these to Disk 1.
4. Run 5 YSOP (described below) and select menu option 6
to create the MEMBERS file. Save this to Disk 2.
5. On Disk 2 place the text files (described below) TEXT-
DESC. PROGDESC, BULLETIN, NEWMEMBR
SCAN, READ. LEAVE, PROGRAMS, and TEXT. Also
add any text files that you want callers to be able to read with
the Text option of RAINBORD.
6. Save on Disk 2 the BASIC programs you want callers to be
able to download to their computers. These must be in
ASCII format and should be given extensions as follows for
lines 980-990 of RAINBORD
POU-Utility
POA-Application
POG-Game
POO-Other types of programs.
Example command: SAVE"MILE MON/POA",A
7. Now you're ready to go! Turn on the modem, and be sure
that it, rather than your printer, is hooked to the RS-232
outlet. Place Disk I in your drive and flLWREMOTE."
After the files on Disk I are loaded, you will be prompted to
remove it and insert Disk 2. Pressing[ENTER] will load the
MEM BERS file, and you will receive the message "RAIN-
BOARD IS READY TO RECEIVE!"
8. The Rainboard is now waiting for callers, and requires no
further attention from you.
9. Each day at a time convenient to you, you should first
"call" the Rainboard yourself, either from another compu-
ter or directly by pressing [ENTER] on the Rainboard key-
board. This will allow you to read messages addressed to
you and to reply to them. Then, turn the computer off and
back on, insert Disk I, and run SYSOP. Use either menu
options I or 2 to view the activity file. If a caller seems to
have had trouble, you may want to leave him or her a
message about it.
10. Use SYSOP MENU option 3 to kill the old activity file
Periodically, you will also want to use option 8 to remove
messages that have been read by their recipients.
1 1. Return to step 7.
Text Files
The subject of text files deserves further comment. There
are two types of text files used by the Rainboard. one of
which provides information to the caller on the use of the
BBS and the other type on various topics of interest which
can be read through the Text function of RAINBORD In
this latter category, I currently have the following: DSK-
BASIC /073, a memory map of the new 1 . 1 Disk BASIC ROM;
COCO BBS/083, a list of CoCo boards; PROGTIPS/053,
programming tips; and FOR SALE/073, sources of good
buys. The extension gives the date of entry, e.g. 093 =Sep-
tember, 1983. When a caller requests a list of text files,
RAINBORD (1080) displays only the filenames that have
numerical extensions. The following text tiles, all of which
have the extension "DAT," are displayed at different times
in the use of the BBS:
TEXTDESC — descriptions of the text files that can be
read by the caller;
PROGDESC — descriptions of the programs available to
callers;
BULLETIN — news of meetings, etc. Note that line 460
of RAINBORD has to be edited whenever you update this
file.
NEWMEMBR — explains use of the bulletin board;
automatically displayed when a caller first joins the
Rain Board;
SCAN. READ, LEAVE, PROGRAMS, TEXT - help
files for each function of the BBS. Just as the Help func-
tion explains each of the Main Menu choices, these files
contain descriptions of submenus and other aid in the use
of the particular function. As an example, the SCAN file
is listed below.
Text files can be created most conveniently with any word
processor program that is capable of producing ASCII disk
files. Several of these are advertised in the Rainbow. If you
don't already have one, the cheapest way to produce your
text files is to RUN'R AINBORD" and use the Leave mes-
sage function to create the files as messages. You'll have to
enter your own initials as the recipient, but they can be
RENAMEDed later with the date extension needed for
RAINBORD's text file function. The example file SCAN
will indicate the necessary characteristics of RainBoard text
files. The line length should be set to 3 1 characters/ line, and
only capital letters whould be used. It is best not to use
hyphens to divide words. Some callers will have other com-
puters and will want to later print what they receive with a
longer line length.

GRAFMESS
The GRA fie MESSage generator program is used for the
creation of the graphic screens displayed by the Rain Board.
Instructions for the use of GRA FMESS are displayed when
the program is run. The user is prompted to select the
creation of a new graphic or the editing of one already in a
file. After indicating either disk or tape storage, a filename is
requested. If one is editing an existing graphic, it is then
loaded from the disk or tape. There is a delay while the
graphic array is processed for editing, and then a blinking
cursor indicates that the program is ready for keyboard
input. If a new graphic is being created, the user is asked for
a CLS value which clears the screen to that color.
The arrow keys are used to move the cursor to desired
locations. To select a particular graphic character, the
[CLEAR] key is pressed. Then two key presses are used. to
enter the hexadecimal value of the desired character. These
values are listed on page 14 of the Nanos reference card.
Each time the "@" key is presed, the selected character will
be displayed. Pressing the back arrow also displays the
character, and this allows rapid erasing of areas. Text char-
acters are simply typed as usual. When the graphic is com-
plete, pressing[SHIFT][CLEAR] will store both the ASCII
file for RAINBORD and the binary file for later editing.

easier than with other printers.
State-of-the-Art Design. The CGP-220 utilizes a
drop-on-demand ink-jet printing system, which
gives you higher quality at lower cost. Unlike ex-
pensive continuous-drop printers, the CGP-220
jets ink only where you specify, mixing colors to
produce seven vivid hues — yellow, violet, red,
green, cyan, magenta and black. And since there's
no ribbon to wear out (or become contaminated
with various colors), the print quality remains ex-
cellent for the life of the ink packs— approximately
four million characters per color.

■ Incredibly Quiet Operation
Fast, High-Resolution Printing in Three
Modes. The CGP-220 prints 2600 dots per second
in the graphics mode with a resolution of up to 640
dots per line. An 80-column text mode gives you
1 2 characters per inch at 37 characters per second
in a 7 x 5 matrix. The CGP-220 plugs into the serial
port of your Color Computer.
Print Any Color Computer Screen. A screen
print utility will let you make multi-color print-
outs from any graphics program, such as our
Micro Painter and Art Gallery programs. Com-
bined with the X-PAD, you can input and print out
beautiful video artwork, business graphs and

October 21
I tend to forget dates and, subsequently, find myself in
"hot water" at least once a month for forgetting a loved
one's birthday, anniversary or even a lunch date. I'm
lucky if I remember my own birthday. And yes, I bought a
pocket calendar ... but I forgot where I put it. Luckily, I
found a program that solves this embarrassing problem.
Bill Bruck's Appointment Book, requiring 32K Extended
Color basic and a printer, handily stores your appoint-
ments for any day within one year. It will print a calendar
with any number of memos per day. though each must be 1 6
characters, or less.
Type in the program and RUN it. The first time you run
the program you must create a datafile, which is a storage
space on the cassette or disk where data is kept (that cannot
be run). If no file is present, the program will look for one
and bomb. The program will check for the presence of the
disk ROM pack, and if it is there, data will be saved from the
disk, otherwise, the cassette will be used.
The default for the datafile names is "DIARY." By using
this name, you can press ENTER when asked for a datafile
name. Occasionally, the program will not run the first time
because of the PCLEARl command. Stay calm and keep
trying, it will work.
First, the program will ask you to input a month, day and
reminder, and end month, end date. Four options are given
after the item is entered:
(Y) — Put in a different item for a different day.
(N) — Return to main menu.
(S) — Put in another item for that same day.
(D) — Put in that same item again on a different day.
To delete an item, press D.
It is necessary to input the beginning month, date and day
of the week (this is only crucial in the printout command),
and ending month and date, so all days and dates will
correspond correctly. Leap year is a special situation. As the
program is presented, February 29 can exist only if you
make it the beginning or end of a given display or printout.
Otherwise, every fourth year will have the wrong day of the
week identified for quite a few dates in succeeding months.
So, to modify leap years, change line 788 by removing
"VB=60 OR" and change line 2030 by removing "D=60
OR."

It's called the premier Color Computer magazine for
good reason. The Rainbow is the biggest, best, bright-
est and most comprehensive publication a happy
CoCo ever had! Is there any wonder we get letters daily
which praise the Rainbow, the magazine one reader
calls "A Pot Of Gold" for his Color Computer?
The Rainbow features more programs, more infor-
mation and more in-depth treatment of the TRS-80
Color, TDP System-100. MC-10 and Dragon-32 com-
puters than anyone else.
Each monthly issue is well over 300 pages and con-
tains more than two dozen programs, some 15 regular
columns and 30 or more product reviews. And adver-
tisments: the Rainbow is known as the medium for
advertisers —which means it has a wealth of informa-
tion about new products every month unavailable
anywhere else! More than 200 companies advertise in
its pages every month.
But what makes the Rainbow is its people. People
like Bob Albrecht, the master teacher of computer
programming. People like Don Inman, the world's fin-
est computer graphics writer. People like Dick White,
one of the most knowledgable writers about BASIC
going. Or Dennis Lewandowski, who has that certain

Join the tens of thousands who have found the
Rainbow to be the absolute necessity for their CoCo.
With all this going for it, is it surprising that more than

We're willing to bet that, a year from now, you'll be

If you wish to move your data from cassette to disk,
follow these directions:
•Put in disk controller. CLOAD program, SAVE'W to
disk.
• Add lines 118 DC=-1 and 1045 DC=1.
• RUN program, but don't save this version.
Immediately save data. Type NEW and run program as
saved on disk. It is a good idea to save your data before
exiting or printing . . . just in case of a mistake.
After entering the appropriate data, your printer will
begin. At your command, the printer will provide you with
data between one week to a full year in a standard calendar
format. As you will see, this program utilizes your printer's
capabilities by taking advantage of expanded and con-
densed fonts, tab controls, etc. It is suggested that you print
two months at a time because the program does not skip
perforations, unfortunately.
Appointment Book is written specifically for the Epson
MX-80 and MX-100 printers. Since different printers use
different control commands, modifications will be necessary
if you do not have these printers. In this program, the
following control codes are used:
Emphasized mode: CHR$(27)"E"(And cancel emphasized
mode — CHR$(27)"F") in lines 680 and 700. If your printer
doesn't have these, eliminate them from the program includ-
ing the semicolon after them.
Double wide mode: CHR$(27)"S" — line 680 (My printer
stops printing double wide at the end of the line. If yours
keeps printing double wide, put the stop code at the end of
line 680). If your printer does not have this, eliminate it,
(including the semicolon) and adjust the space between the
days of the week to get them to line up properly.
Compressed mode: CHR$(15) — line 700. This is necessary
for the printout to make sense. Otherwise, you need a major
rewrite of this whole section and rethinking of how many
spaces are available. Substitute your code for this one.
An important note: LPVIIand DMP-100 printers — This
program will not run because these printers do not have
compressed characters.
LPVIII and DMP-200: Use the following lines:
680 PRINT#-2, CHR$(27);CHR$(19);CHR$(27);CHR$
(14);" S M (the rest as in current line 680)
700PRINT#-2,CHR$(27);CHR$(20);CHR$(27);CHR$(15)
Bill Bruck's Appointment Book has been a real life — and
love — saver for me. I no longer get dirty looks and the silent
treatment for forgetting important dates. Now, all I need to
do is find a solution to that darned name forgetting problem.

FINALLY!
A REAL SPREAD-SHEET PROGRAM FOR THE COLOR COMPUTER
DYNACALC™
Business people use spread-sheets to organize columns and rows of figures.
DYNACALC simulates the operation of a spread-sheet without the mess of paper and
pencil. Of course, corrections and changes are a snap. Changing any entered
value causes the whole spread-sheet to be re-calculated based on the new
constants. This means that you can play, 'what if?" to your heart's content.
But DYNACALC isn't just for accountants. DYNACALC can be used for just
about any type of job. Not only numbers, but alphanumeric messages can be
handled. Engineers and other technical users will love DYNACALC s sixteen-digi t
math and built-in scientific functions. There's even a built-in sort command,
so you can use DYNACALC to manage smal I data bases - up to 256 records.
DYNACALC will let your computer do just about anything you can imagine.
Ask your friends who have VisiCalc, or a similar program, just how useful an
electronic spread-sheet program can be for all types of household, business,
engineering, and scientific applications.
DYNACALC is designed to be used by non-programmers, but even a Ph.D. in
Computer Science can understand it. Built-in HELP messages are provided for
quick reference to operating instructions.
DYNACALC has a beautifully simple method of reading and writing FLEX data
files, so you can communicate both ways with other programs on your system, such
as the Text Editor, Text Processor, Sort/Merge, RMS data base system, or other
programs written in BASIC, C, PASCAL, FORTRAN, and so on.
Except for a few seldom-used commands, DYNACALC is memory-resident, so
there is little disk I/O to slow things down. The whole data array (worksheet)
is in memory, so access to any point is instantaneous. DYNACALC is 100$ 6809
machine code for blistering speed.
Color Computer DYNACALC works with the FLEX operating system from Frank
Hogg Laboratory (64k required). If you aren't already using this powerful
operating system, we have a special deal for you: order DYNACALC (regularly
$200)- and FHL Color FLEX (regularly $99) together for only $250.

Master Messenger
By Alan Davenport
T| yf aster Messenger is a program for network ad-
l\/H diets, like myself. It allows the user to write
.1. V.M. messages for bulletin boards off line and reduce
connect time, phone bills and most important, save money.
Master Messenger was specifically designed to be compati-
ble with CompuServe's Special Interest Group (SIG) mes-
sage boards. It also can be used to write letters to be sent by
electronic mail (EM AIL) on the CompuServe system. Using
this program, a network addict no longer need be afraid to
spend too much time and money answering messages.
Answers can be typed at leisure off line and uploaded any-
time. The only danger is to the person that you are writing
to — the danger of having to read a long message! Your
answers to messages will be better, less hurried, and more of
a joy because you will no longer be rushing to answer with
one eye on the all-terrible clock.
Master Messenger is user-friendly. There are error traps
so that you will not have to worry about typing a long
message and then lose it.
The program has these features:
Allows typing of uploadable text compatible with
smart terminal programs.
Automatic line numbering of message.
Listing of the text to the screen or to your printer.
Edit a line by replacing an error in it rather than re- 1
typing the whole line.
Insert lines in the middle of the body of the text.
Storing of text to disk or loading of an old file from disk
to be re-sent, finished, or edited.
List your disk's directory on your printer.
Program Use
Master Messenger has been designed for ease of use; it has
been thoroughly tested in actual use for several months and
has been steadily revised. This is the 10th version. Although
it is easy to use, it is important that you read these instruc-
tions. When you first type RUN.you will get a syntax error.
Just type R UN again. This is not a bug in the program, it is
caused by Extended Color BASIC'S handling of the PC LEA R
command. After typing RUN the second time, you will be
greeted by the main menu. To start entering text, select [I],
Just type until you have typed about two lines worth of text
onto the screen then press [ENTER]. Your line is now stored
42
Ui» RAINBOW Nuotmbf
in memory. If you type more than two lines, you may exceed
the maximum line length of 79 characters (two lines is 64
characters) allowable by CompuServe's SIG message
boards. If you exceed the maximum length, you will be
informed, the line will not be entered into memory, and the
line will be listed so that you can break it into smaller pieces.
Continue entering text this way until done.
At the bottom of the screen is a display showing how
many characters long your message is. CompuServe docu-
mentation says that you can enter a message up to 2,500
characters long. It is actually only possible to store a mes-
sage about 2K (2048) characters long. There will be an
audible and printed warning when you are have only 200
characters left. If you excede the maximum allowable mes-
sage length, Master Mesenger will not store the line and you
will be given the choice of editing the message or saving the
first part and finishing your message as a separate file and
uploading it as a separate message.
At any time, you can return to the main menu by typing
three Ms [MMM] on a blank line or at the end of a line of
text. If you do, however, that line will not be entered into
memory. You can also delete the current line being typed by
entering three Ds [DDD] at the end of the line.
Editing
When you are finished typing your message, you can then
list, print or edit it. Select [2] from the main menu. You will
then see another menu. Pressing[ 1 ] on the new menu will list
the message to the screen. If, when you list your text, you see
a line with an error, note the line number so you can edit it
later. Press [2] to print the message. You will be asked if your
printer is ready. If your printer is not ready press [N],
otherwise press [Y]. To edit, press [3]. When you select
editing, you will be asked for a line number. If you just hit
[ENTER], Master Messenger will start at the first line. If
you continue hitting [ENTER], the next lines will come up
in sequence one at a time. If you decide to edit a line, enter a
replacement string. Here is how it works. Those familiar
with CompuServe's SIG editor will find that Master Mes-
senger works in the same way; say that you mistyped the
word "THE" as "HTE." When asked for the "string to
replace," type "HTE." You will then be asked for a replace-
ment string. Simply type "THE"correctly and hit [ENTER].
The line will then be fixed, printed and you will be asked if it
is OK. If it is not OK press [N] and the line will not be
changed. You will then be given the chance to correct the
line again. When done press [Y] and the next line will
appear. At any lime, you can enter three other functions
when asked for the "string to replace." As mentioned before,
entering [MMM] will return you to the main menu. [BBB]
will move you back a line. Entering [DDD] will cause the
current line to be deleted from the memory.
Other Functions
From the main menu you can also perform other func-
tions. To load a file from disk, select [3]. Just enter a valid
filename and it will be loaded into memory. The file must be
stored in the ASCII format. Any old message will be
scratched (erased) and the new file from the disk will take its
place. You can clear memory by selecting menu item
number [4]. To store your text, press [5]. You will be asked
for a filename. Enter any valid filename with extention and
disk drive number (F1LENAME.EXT:!). If you type a file-
name that is too long, you will be asked for another.
Master Messenger also checks to see if the disk that you
are trying to store your text on is full. If it is, you will be
asked to substitute another. When you have inserted a dif-
ferent disk, just press [ENTER] and your text will be stored
or enter an [M] to return to the menu. Entering [6] from the
menu will end the program. You will be asked if you really
want to (so you do not accidentally lose your message!).
Press [E] and Master Messenger will end, delete itself from
memory, and reset BASIC. Use care here! When you first type
it in, SA VEa copy before trying this or you will have to do it
again! Selecting menu item [7] will allow you to insert a line
in the middle of your message. You will be asked for a line
number. Enter the number of the line that you want to insert
the new line before. If your text is long, it may take a few
seconds to open up a space for your new line. Menu item [8]
will list the directory of any of your disks on your printer. It
is useful to have a copy of your disk's directory handy when
on-line, especially if you are sending multiple messages and
cannot remember a filename!
1 have been using this program without problems for
several months now using Eigen System's Colorcom/ E
smart terminal program. To send a message using Color-
com/E select [R] from the menu. To leave a message on a
CompServe SIG, select transmit option 1, "NONE." Enter
[L] at the SIG's function prompt, then enter who you want
to send your message to. When you see the first line number,
(1:), press the down arrow on your keyboard and the
number [2]. Your message will then be uploaded (transmit-
ted) to the SIG message board. It will appear that the
message is not being received properly, line numbers will
appear in odd places, but when the message is completely
uploaded, press [ENTER], type [P], then press [ENTER]
again and you will see that your message is stored on the
board. After you see that it is okay, type [S] and a section
number (SO) and you will receive the message "Message
#12345 stored."
To send EM AIL (electronic mail), first load your text into
Colorcom / E by selecting transmit option [2], "ADD
HEADER." Then to go to CompuServe's EMAIL section,
type [GO EM A]. On the menu that you see, press [22], "To
send mail." On the next menu, select item [I], "F1LGE
Editor." When you see "ready." press I and the number [2]
and your message will be sent. When it is all sent, type [/ EX]
and you will return to the menu. Select [6] and answer the
questions as to who you want to send your message to.
For other terminal programs, refer to their instructions
for how to upload a file.
There are many error traps built in Master Messenger,
however, it may still be possible to crash the program. (I/O
ERROR on a disk, etc.) Many times, it is possible to recover
from an error by typing GOTO 480. (The start of the main
manu.) In many cases, your message will still be there.
That is it! This program has saved me hundreds of dollars
in connect time. I hope that you find it as useful as I have. If
you have questions, you can reach me at CompuServe
Number [72215,743] or write me at 31 Madison Drive,

ANNOUNCING
The VIP Library™
With a Terrific Sale!
Nelson Software Systems is now Softlaw Corporation, under
new management. Our Super "Color" Library programs have
also undergone a name change. All programs are the same
unbeatable Super "Color" Library programs you've heard so
much about, but with new VIP names. To introduce our VIP
Library we are having a special sale on the following pages. Our
low prices for such high quality can't be beat so get started today!
The Library Concept
State of the Art, Quality, Integrity,
Compatibility and Affordability. Five
things good software must possess.
Five things that 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 affordably priced.
State Of The Art
All Library programs are written in
machine code specifically for the
Color Computer, to work without
the interference of a separate
operating system such as FLEX. From
this comes speed and more work-
perfectly with every Color
Computer, from 16 to 64K. The most
advanced hardware and software
techniques are used to place
programs in rompak cartridges for
instant loading and total workspace
with any Color Computer.
Perfection With 16, 32 or 64K
The programs do not depend on
BASIC, and so allow total compati-
bility and workspace with any size
Color Computer, even 64K. 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 with
BANK SWITCHING to fully use all
64K, thus giving an astounding 61 K
of workspace with the rompak cart-
ridge, and up to 51 K with a disk
Lowercase Displays
State-of-the-Art graphics allow
instant use of four display colors, and
eight lowercase displays featuring
descending lowercase letters. You
can select from 51, 64 or 85 columns
by 21 or 24 lines per screen, with
wide or narrow characters in the 64
display. These screens provide a
pleasant and relaxing way to perform
your tasks, with as much text on the
". . . PICTURE getting your
instantaneous investment report

and data from your database with

with VIP Library 1 " programs ..."
screen as is possible. Each program is
easy to learn and a joy to use. We
take pride in the stringent testing
done to make these programs per-
form flawlessly. Every feature, every
convenience, sleek, simple and
elegant.
Total Compatibility
All Library programs are
compatible. Transfer and use of files
between programs is easy and
carefree. What's better, when you
have learned one program the others
will come easy. And every program is
the best of its kind available.
The Library Programs
For your writing needs is the VIP
Writer'", and its spelling checker, the
VIP Speller'". For financial planning
and mathematical calculations you
can use the VIP Calc'". To manage
your information and send multiple
mailings there is the VIP Database'".
For sending all these files to and
from home or the office and for
talking to your friends you can have
the VIP Terminal'". Finally, to fix
disks to keep all your Library files in
good repair we offer the VIP Disk-
Mini Disk Operating System
The Disk versions each have a Mini
Disk Operating System which will
masterfully handle from 1 to 4 drives.
It offers smooth operation for such
features as the ability to read a
directory, display free space on the
disk, kill files, save and automatically
verify files, and load, rename and
append files. Library programs simply
do not have the limitations of BASIC.
Professionalism
The Library comes handsomely
bound in gold-embossed, padded
leatherette binders to grace your
work area with the professionalism it
deserves. Welcome the VIP Library'"
into your home and office.
A description of each of the
Library programs, with the
special sale price, is contained
in the following pages. Please
indulge!

An Automatic Phone Dialer
For Radio Shack's Modem II
By Jorge Mir
A few months ago. 1 decided to "byte" the bullet and
purchase a Radio Shack Modem II to replace my
old one. The ability to dial a phone number from the
keyboard, as well as the auto-answer capability of such a
modem, attracted me to my new acquisition.
I am constantly using several favorite bulletin board ser-
vices (some are long distance calls, such as Connection-80)
as well as CompuServe and The Source. Keeping track of all
these different phone numbers while having a computer at
my fingertips did not make any sense at all. So, Telecom was
"born" to make things easier for me.
Telecom will automatically dial any telephone number
included in the data statements. It will identify it as a local or
long distance phone number and it will determine if it is a
voice or data phone call. If it is a data type phone call, it will
load your terminal program and EXECuie it after which
you can press BREAK and type in an "X" to activate the
modem for dialing the phone number. If it is a voice type
phone call, the modem will dial the phone and ask you to
pick up the handset after it starts ringing.
The program has sufficient prompting throughout its vari-
ous subroutines, so detailed instructions are not necessary.
Also, I have added sufficient REM statements to explain
what each section of the program is to accomplish.
Please note that the phone numbers are entered as data
statements which contain the name of the person or service,
the phone number and an identification code to determine
whether the number is a computer service (a number I), or a
phone number for voice communications (a number 2).
Step 650 checks to see if the number is longer than seven
digits. If it's longer than seven digits, it recognizes it as a long
distance phone number and adds additional digits for dial-
ing through phone services such as MCI. In this case, 1 have
used the phone number 222-3333 and account number
1 2345 for illustration purposes and you will have to change
the program step to your own number and account. Note the
two "ps" added for pausing approximately four seconds to
wait for the tone on these services before you can enter the
account code followed by the phone number to be called. If
you are not using this type of service, just replace these
numbers with a "I" to enter the direct dialing longdistance
network.
A few data statements have been added to illustrate the
format required.
(Jorge Mir, a Certified Public Accountant, is currently
controller of a Fortune 500 Corporation. Personal
computing is his main hobby and he publishes most of
his original work through the Rainbow.)
Please note that step 290 loads a disk version of Videotex.
You will have to change this step according to the type of
terminal program you have.
As a final point, if the telephone number you are search-
ing for is not included in the data statements, you will have a
chance to enter it from the keyboard. Of course, you can also
stop the program at that point and add it to the data state-
ments after which you should save the program so that it
would contain that phone number next time you call for it.
Although the program is designed for a Radio Shack
Modem II. it can be changed to work with other types of
programmable modems.

The Shell Game
By Dale L. Puckett
Rainbow Contributing Editor
Welcome to KISSable OS-9. Month Two. In our
first column we talked about OS-9 in general and
tried to get you excited about the prospect of
being able to do more than one thing at a time — or even let
more than one person work on your CoCo at the same time.
We told you that OS-9 works because it is made up of a
number of small modules that can be tailored to fit any
hardware you want to run it on and introduced you to a few
modules which are common to all versions of OS-9. This
month we'll move on to take a look at the SHELL — the
heart of OS-9 operation.
An Invitation
As the newly elected president of the OS-9 User's Group, 1
would like to invite you and your local CoCo club to join us.
One of the goals of our group is education. We want to help
others learn OS-9. By the time you read this our officers will
have held their first organizational meeting on Compu-
Serve. We'll pass along the details and our new address as
soon as we have it. We're hoping that Color Computer clubs
around the country will become the heart of our OS-9 users
group.
What Do You Want To Know About OS-9?
As we mentioned during our first column last month, this
is your column. We will attempt to give you the coverage
you want about CoCo's new OS-9 operating system. We'll
try very hard to find answers to your technical questions
about OS-9. I plan to reserve a portion of the column each
month for these answers. This is where you come in. If you
have questions — or are just a little confused about this
complex operating system — jot them down and mail them
to me at Rainbow. We'll be using your letters to keep the
column on track.
Again, Why OS-9
I looked back over last month's column and noticed
something which told me I should give you a recap. Last
( Dale L. Puckett is a freelance writer and programmer
who has worked with the Motorola family of microp-
rocessors since 1976. He just completed his first book,
"A Complete Tour Guide to BASIC09, "this summer. It
is being published by Microware and will be available
this fall. He is the author of DynaSpell. Readiest.
Esther and Help, which are available from Frank
Hogg Laboratories. He serves on the Info World
Software Review Board and is a Chief Warrant Officer
in the U.S. Coast Guard.)
month, we only gave you technical reasons why you should
learn and use OS-9. I sort of got the cart before the horse.
Let's try again.
The most important reason is the fact that OS-9 is on its
way to becoming the standard operating system for 6809
based micros. I didn't realize how many people were using
OS-9 until 1 attended the seminar in Des Moines. More than
50 different microcomputers run OS-9 now. These compu-
ters are alive and well on the SS-50 buss, the Motorola
Exorbus, the STD buss and yes, even the S-100 buss. OS-9 is
also running on several of Europe's major computers and
several systems in Japan.
Now that Tandy has made it the Color Computer operat-
ing system, there will be tens of thousands of OS-9 users in
the United States within a year. Also, the Tano Corpora-
tion, who bought the licensed OS-9 and plans to make it the
standard operating system on those computers.
If you're looking for more hardware reasons to consider
OS-9, think about the future. What happens when you fall in
love with OS-9 and decide to put everyone in the office on
your system. While there's not enough memory in your
Color Computer to do the job, you won't need to look far to
fill your expansion itch. For example, the GIMIX Level 111
machines access a million bytes of memory and run a half
dozen terminals at the same time and do it very effectively.
The direct memory access disk controllers and intelligent
input/ output cards make it all possible.
Yet, hardware that runs OS-9 is only half the story. How
about software? Why should you buy OS-9? It's new so
there's probably no software support for it, right?
Wrong! Just about every major language and other type
of system software that is available on the IBM and clones,
and the Apple, et al, is running today on OS-9 computers.
And, most of these programs run faster on our 6809s. The
applications software you need to run your business is run-
ning right now, too. And most of it is superior to similar
programs running on those Z-80 and 8088 machines.
DynaCalc for example, is superior to VisiCalc. DynaStar
does everything WordStar does — besides, it's easier to use.
OK, I realise not everyone likes WordStar . In that case, try
Stylo. It also beats the pants off anything the IBM clan can
offer. All the utilities you need are running right now too.
There's DynaSpell. DynaMail and Dynamite to name just
three. Would you believe they all come from different com-
panies? And don't forget: Computerware's Inventory Con-
trol and Order Entry System, or the RMS record manage-
ment system to name just a few applications packages.

the RAINBOW November 1983
II you don't believe there's a lot of software out there for
OS-9, ask Dan Downard, our Technical Editor at Rainbow.
I understand that Frank Hogg buried him in OS-9 software
that is ready to be set up to run on CoCo. Speaking of
Frank, we got a positive progress report on O-PAK from
him just as we went to press. They've done their homework
and should be shipping the 5 1 x 24 character high resolution
screen by the time you read this. It looks now like you'll even
be able to escape from the text mode and use the graphics
commands already in CoCo's memory. This means you'll
even be able to mix graphics and text on O-PAfCs screen.
The copy routines are coming along fine also and will prob-
ably have a command something like:
OS9:XCOPY FLEX%/dO/flexnameOS9%/dl/OS9path
Of course you'll be able to read and write Radio Shack
Extended Disk BASIC disks from OS9 as well as FLEX
disks.
Those Special Keys, Revisited
We picked up some new information in Des Moines about
those special keys we told you about last month. "Control
Q," for Quit has been changed. It is now "Control E." Now
instead of "Quitting" a process, you can "End" it. This
change was necessary because OS-9 Level 11 systems recog-
nize the standard X-On and X-Off characters used by many
terminals to tell the computer to stop sending. X-On is
normally "Control Q"on these terminals so there would be a
natural conflict.
And we forgot to tell you something really special about
the "Control C" key. You can generate it by holding down
the "Shift" key while you strike the "Break" key or, you can
hold down the "Clear" key while you strike the "C."
Remember when you are running OS-9 "Clear" means
"Control." When you type this command you will imme-
diately see the OS-9 prompt on CoCo's screen. But, that's
only half the magic. Try this:
OS9:list filename >/p
As soon as you see that your file is being listed to your
printer, type the "Control C" command. Watch what
happens.
You'll notice the "OS9" prompt reappear on CoCo's
screen. But isn't there something strange going on? Why is
your printer still printing? You have just told OS9 to run the
printing job as a background task. To prove it type the list
command again but leave off the ">/p." CoCo's screen
should start to fill with the listing while the printer continues
to print.
Last month we said that an operating system is nothing
more than a piece of software that lets you communicate
— talk if you please — to many different types of hardware.
It lets your printer or disk file understand what you are
saying on the keyboard. It gives you a way to hook CoCo to
another computer through a telephone line and modem.
Meet the OS-9 SHELL. When you talk to OS-9 by typing
a command on CoCo's keyboard, you are talking to the
SHELL. The SHELL is a command interpreter that trans-
lates the words you type into an action by the computer.
You'll know when you're talking to the SHELL because
you'll see this.
OS9:
When you see this prompt, you'll know that SHELL is
waiting for you to enter a command. To do this, you simply
type a command line followed by a carriage return. You can
use lowercase letters, uppercase letters or a combination
—the SHELL doesn't care.
Let's take a closer look at an OS-9 command line. The
first thing following the prompt should be the name of a
program. It can be the name of a program located in a
module in your computer's memory or the name of a file that
stores your program on a floppy disk.
It can be 6809 machine code that executes directly, a
module containing compiled intermediate code from a
higher level language like BAS1C09, Pascal and Cobol or, a
procedure file. Here's what happens when you give the
SHELL a program name.
If it finds a module in memory with the name you have
typed, it will run the program. If it doesn't find the program
in memory, it looks for a disk file with that name in the
current execution directory. If it finds the file, it loads it into
memory and runs it.
If the name you typed is not the name of a module in
memory or a file stored in the correct execution directory
you still have another chance — it may be a procedure file.
The SHELL knows this, and searches your working data
directory for a file with the same name.
"The SHELL is a command
interpreter that translates
the words you type into an
action by the computer."
If the SHELL finds a file in the data directory, it assumes
it is a procedure file and runs it. A procedure file is a special
case. Instead of holding object code that runs on your com-
puter, or I-code that is executed by a high level language, it
contains a text file that looks just like one or more command
lines you could have typed from CoCo's keyboard. When
the SHELL executes a procedure file, it reads text one line at
a time — as if it were reading data from the keyboard. It then
executes the commands in that line.
The program named the SHELL reads from your key-
board or a procedure file is usually followed by one or more
parameters. A parameter gives directions to the program. It
is separated from the program name by a space or spaces.
For example, if you want to list a file called "Rainbow" to
your terminal you must type:
OS9:list Rainbow<RETURN>
If you want a "hardcopy" of the same file you can type:
OS9:list Rainbow >/p<RETURN>
In fact, you can even send the listing to another file:
OS9:list Rainbow >CloneOfRainbow <RETURN>
Just like we've been saying, OS-9 is a very versatile operat-
ing system.
November 1983 the RAINBOW 59
Sometimes the parameters in your command line will be
options or modifiers. For example, when you want to list the
names of the files in your working data directory to CoCo's
screen, you type:
OS9:dir<RETURN>
Here's a way to get more information about the files. Try:
OS9:dire<RETURN>
This command lists all available statistics about each file
in the working data directory. The "e" is an option that
means list the "entire"directory record. Speaking of directo-
ries and options. If you would rather see the names of the
files stored in your current execution directory, type this:
OS9:dirx<RETURN>
Or, if you want to see all available information about the
files stored in your current execution directory, type:
OS9:dirxe<RETURN>
Pathlists And Device Names
When you used the LIST command above, you were
using a filename as a parameter. In this case the parameter
was an abbreviated pathlist. Since you didn't pass any
information about a device or directory, L/STassumed that
the file was located in your current data directory. But. what
do you do when you want to access a file that is not stored in
your current data directory?
No problem, it is easy to enter a complete pathlist. A
pathlist is just a description of the complete route your data
must take before it arrives at its destination. It may hold the
name of a mass storage file, a directory file or an Input/ Out-
put device. Microware chose the term "pathlist" instead of
"filename" because you must often give the SHELL a list
that contains more than one name.
For example, many "pathlists" contain a device name,
and one or more directory names as well as the name of a
data file. Each name in the pathlist is separated by a slash
"/."
Follow these rules when you work with pathlists. Pathlists
should contain names that describe three things.
1. Names of physical I/O devices
2. Names of directories
3. Names of regular files
Each of these names may be made up of as many as 29
characters or as few as one character. They must begin with
an uppercase or a lowercase letter. After that they may be
made up of any combination of the following characters.
1. All uppercase letter: (A — Z)
2. All lowercase letters (a— z)
3. The ten decimal digits: (0—9)
4. The underscore: ( )
5. The period: (.)
Here are some legal names:

the RAINBOW November 1983
If you're wondering how OS-9 can tell the difference
between a filename and a device name, here's the secret.
A device name always starts with a slash. If the device can
hold multiple files — a disk drive for example — another
slash followed by a directory or a filename usually follows
the device name. If however the device cannot handle multi-
ple files — a terminal or printer for example — nothing
follows the device name.
Here are a few standard OS-9 device names:
Name
Device
TERM
Primary system terminal
TI.T2
Additional terminals
P
Parallel printer
PI
Serial printer
DO
Disk drive zero
Dl
Disk drive one
You probably noticed these names in the list of modules
we gave you last month. That's because the names above are
the names of modules that hold "device descriptors." The
device descriptor "TERM" for example, tells SCF, the
sequential file manager, that CoCo's screen is 16 lines deep,
etc. It also points SCF to the driver module CCIO so that it
knows where to go to get characters from CoCo's keyboard.
Remember, if you want to name these devices in a pathlist
you must type a slash before their name. Here are some
common pathlists.
Group 1:
Group 2: /DO /dO/cmds
/dl / RAINBOW/ First.Month
The pathlists in Group 1 refer to devices that cannot
handle multiple files.
The pathlist "/ dO" refers to disk drive number zero. If you
needed to know the names of the files stored on this drive,
you would use this command line:
OS9:dir /dO <RETURN>
After you hit the <RETURN> key, the names of all
directories and files that you have previously saved on the
disk installed in drive "dO" will be listed on CoCo's screen.
Let's try another command line:
OS9:dir /dO/CMDS<RETURN>
This command lists the names of all files stored in a
directory named "CMDS" located on the disk installed in
drive "/dO."
Let's take it one more step:
OS9:Iist/dl/RAlNBOW/The.Article<RETURN>
This command prints a listing of a file named "The. Arti-
cle. "The file is located in a directory named "RAINBOW"
on the disk you have installed in device "/dl."

OS-9 has many advanced features and we'll introduce you
to a few this month.

Computer Shack has become one of the sofware leaders
tor the COCO in less than 3 months. In the July Rainbow
we advertised one product, DFT. In this issure we have 1 1
new games, 5 utilities, and 1 business program. And, all
our games are exceptionally good! I n fact we have 5 of the
top 1 games. We do more than copy arcade games. We
try to originate, to be better! To be different!
WE are the only company that offers 4 original games for
the COCO all of exceptional quality; Two great games that
you can play with 2 players simultaneously; Games with
multiple screens and playing levels so you don't get bored
after a few hours; 24 hour shipment of most orders; Toll
Free order lines; Fantastic color packaging and ads; and
much much more. We want to be your favorite software
publisher. We want togive you more for your money. If you
haven't tried a Computer Shack Software program don't
delay try one today. If you are writing a program for the
COCO we would like to help you market It.
DFTII
The best value in terminal programs. One of the easiest
modem programs to use yet it can do things no other
modem program can. Itwill transfer basic programsfrom
a Model l/lll to a Color Computer. Transfer machine
language programs from one COCO to another COCO
without any conversionsXhat mode, ASCI I transmit and
receive mode, and much, much more.

SMALL BUSINESS BILLING SYSTEM
Imagine having all your customers at your finger tips
with the ability to print invoices or monthly bill easily and
quickly. Now imagine being able to keep a running total
of all customer accounts without having to even pick up
a calculator. Its all automatic, just say so and it performs.
you can acces9 a customer file, print a invoice, add sales
tax, shipping cost, interest, and even service charges
with the simple ease of pushing a button. All at once
you'll have time to get the important things done instead
of constantly worrying about customer accounts. That's
what you get with a BILLING SYTEM. Computer Shacks
Small Business Billing System, not an elaborate ac-
counts receivable program, but a simple and effective
way of keeping track of people who owe you money.
DISK ONLY $29.95
SUPER ZAP
At last the ultimate zap utility. Computer Shack and J.
Weaver Jr. bring you the SuperZap. A few of the things
Super Zap will do. It will repair disks, let you change
programs on the disk, a format utility (regular format or
format without erase), a high speed backup, copy and/or
verify sectors, a Granule map, kill files, list files, modify
sectors in ASCII or HEX, zero out sectors and more. All
this for only $29.95.
SUPER INPUT
Super Input is a machine language subroutine that you
can add to your basic programs to make them look and
run like they were written by a progessional. This is a
fantastic inkey routine that lets you input and edit your
data routines. Say you are dealing with an address list
and you type in a name, address, city and telephone
number and you notice that you spelled the name
wrong. All you do is hit the up arrow and go back to the
name line ane type over the mistake. You can use the
arrow keys to move all over the screen. When inputing
information the curser will automatically go to the next
input space. In other words you draw the screen and
then go back to the top for data input. Like the fancy
machine lanauage programs do.

During normal operation all input for your programs will
come from OS-9's standard input path. Likewise all output
either goes to the standard output path or the standard error
output path.
Reports, listings and other data generated by your pro-
grams are usually sent to the standard output path. Error
messages and various prompts are routinely sent to the
standard output path. Both output paths normally send
characters CoCo's screen.
When you redirect the input you tell OS-9 to get its input
somewhere else. Likewise, when you redirect the output you
tell OS-9 to send its data somewhere other than the screen.
For example, when you sent the directory listing to the
printer earlier in this chapter, you were redirecting the out-
put to the printer.
There are three redirection operators that you will use
when you give commands to the SHELL:
< means redirect the standard input path
> means redirect the standart output path
» means redirect the standard error output path
There are many ways to use these operators. You may
redirect the input to your program from another terminal
plugged into CoCo's RS-232 jack or from a modem. Or. you
may send output to a disk file for later printing. There is no
end to the possibilites.
About Memory
Some OS-9 programs need very little memory to run.
Others require thousands of bytes. This is not a problem
however because the header of each program module tells
OS-9 the minimum amount of memory needed to run a
program. However, when you need more memory, it is an
easy matter to request more with OS-9's memory size modi-
fier. There are two ways to do this.
OS9:copy #8 myfile yourfile
OS9:copy #2K hisfile herfile
The first command above tells OS-9's copy utility to use
eight 256-byte pages of memory — a total of 2048 bytes. And
believe it or not, the second example also gives the copy
command 2048 bytes to use. It is requesting two "k" or two
thousand bytes of memory.
There are also several ways to run a series of OS-9 pro-
grams. You can run them sequentially — one after the other;
you can run them concurrently — all at the same time; or,
you can synchronize them so that the output of one feeds the
input of another using OS-9's pipes.
There are two ways to run programs sequentially. You
may type one command line followed by a carriage return,
wait for the program to finish and then type the next com-
mand line — or, you may type more than one command on a
line. You must use a semi-colon to separate the commands if
you chose the second method. Here's an example:
OS9: copy hisfile herfile ; dir>/p<RETURN>
This command will copy the file named "hisfile" from the
current data directory to a file named "herfile" in the same
directory. It will then immediately print a listing of the
current data directory on your printer.
If you want to run more than one program at the same
time you must ask OS-9 to execute the programs concur-
rently by using an ampersand, "&."
You may run any number of programs at the same time.
The CoCo's memory will be the only limiting factor.
Pretend for a moment that you have just finished an
assignment in school. You need to print it so you may turn it
in to your instructor, but at the same time you need to be
working on another term paper. To do both jobs at the same
time, try this!
OS9:list Englishll. Assignment >/p&&004
OS9:edit Term.Paper Hisiory
Just like magic, the printer will start right after you hit the
[ENTER] key. Yet, the familiar OS-9 prompt will pop on
CoCo's screen almost immediately. As soon as it appears
you can type the next command line and start the editor. The
printer will run as long as it needs to print the English
assignment. It won't bother your editing at all.
Logging On a Timesharing Terminal
With OS-9 you can do more than just print one file while
you are editing another. One of the major uses for concur-
rent execution is terminal timesharing. For example, you
could use your editor to write a news release about a new
product using CoCo's keyboard and screen while someone
else in the family runs a BASIC09 program to balance the
check book. First, plug a terminal into CoCo's RS-232 jack,
then type the following:
ON COCO:
OS9:tsmon /tl&&005
OS9:
YOU'LL SEE THIS ON THE OTHER TERMINAL
OS-9 Level I Version 1.0 Timesharing System 8/19/83
21:30:35
Use name? esther
Password:
Process #5 logged 8/19/8321:31:36
Shell
OS9:
CoCo has prompted you to go back to work. But, while
you're writing that news release, your wife can probably
finish the checkbook. CoCo will pay for itself in no time.
When you first run the timesharing monitor program,
TSMON. nothing happens. The terminal remains idle until
someone hits its return key.
Also, when using a terminal with CoCo, you must log on.
To do this you enter your name and the proper password.
You will need to give everyone in the family passwords
before they try to log on the first time. If they don't know the
magic word, OS-9 won't allow them to compute.
To log off a CoCo timesharing terminal, you need only hit
the ESCAPE key. This represents an end-of-file signal and
returns your terminal to an idle state.
You Can Feel Secure
While timesharing CoCo with OS-9 you won't need to
worry about someone else writing in your data files. The
system protects you with its file security system.
Each OS-9 directory and file has several attributes that
tell the system who owns the file and who may use it. They
are:
1. Write permission for owner.
2. Read permission for owner.

3. Execute permission for owner.
4. Write permission for public.
5. Read permission for public.
6. Execute permission for public.
7. A "sharable" attribute.
8. A directory attribute.
Let's explain the special cases first. If the "sharable"
attribute is turned on, OS-9 will not let two users use a file at
the same time.
The directory attribute tells OS-9 that a file is a directory
file. A directory file is special because it cannot be changed
by the user. To change a directory or delete it during an
operation would create total havoc with the file system. In
fact, there would no longer be a system.
The other file security attributs almost explain them-
selves. They work because OS-9's file system automatically
stores the user number associated with a process when it
writes a file. If you are the owner of a process, you will own
any files it creates.
If you CREATE a file with none of the public attributes
set, you will be the only person that can READ. WRITE or
execute that file. You may even ask the system to protect a
file from you. For example, after getting a mailing list in
final form, you may clear both the public and owner
WRITE permission attributes to prevent accidental deletion
or modification.
Summary
By now you should be fired up and ready to go. Run
through the SHELL command lines we used this month and
practice with your own. Don't be afraid to make a mistake.
The worst thing that can happen is an ERROR #XXX
message.
Next month, thanks to Rich Hogg, we'll show you how to
change a byte in memory here and there to speed up your
disk drives and if you are using double sided drives, we'll
show you how to make the opposite side of drive/ d0,/d2.
etc. We'll also introduce you to pipes and show you how to
copy and entire directory with one swift command, via a
"pipe." We would pass along the information now but we're
not sure the advance version of OS-9 that Tandy provided
the Rainbow is the same as the Production version. As soon
as we can test our changes on a production version, we'll
print this information.

omeday soon a bleary-eyed indi-
vidual may sit down and write a |
k^J simulation program about what it j
was like to be chief judge of the Rain- |
bow's first annual Simulation Contest. |
It should be a good one because it will
include a dazzling array of graphics,
super sound effects and dozens of mind-
beading options.
Other special effects will include get- 1
ting buried under stacks of cassette j
tapes and disks and dozens of pages of j
instructions. He'll be forced to purchase
a new color TV set when his old one
suddenly loses the ability to distinguish I
green from red and/ or blue. There'll be I
visits to a friend's house to have a disk I
program converted to cassette. There
will, of course, be more I/O errors and'
seemingly dozens of PCLEAR1 state-!
ments. And, if he's as fortunate as I am, J

ion, will not keep changing their minds. I

But the real joy will be in sampling a wide variety of
simulation programs, the quality of which leaves him in awe,
anticipating what kind of programming developments must
surely lie ahead for CoCo lovers in the very near future. Via
his dream machine, he will: battle the Civil War and see the
world destroyed during World War III, travel to the Moon,
to Mars and beyond, conducting experiments along the
way; go bankrupt running a restaurant, make a million as a
manufacturer, and break even as a clothing store proprietor;
run for President of the United States; take responsibility
for mid-air collisions as an air-traffic controller; drown
while learning to sail or taking part in a colonial sea battle;
and experience the thrill of victory in the seventh game of
baseball's World Series.
He will, at times, experience exhaustion. He will be per-
sistent, however, playing the programs over and over, mak-
ing notes of the fine points, the strong points and the weak-
nesses. And in the end. like they say, the cream will rise to the
top, the judges will reach consensus, and the winners will be
rewarded.
Entries were received from readers across the country,
from such places as Solana Beach. California; Jupiter, Flor-
ida: Crivitz, Wisconsin; Downers Grove, Illinois; and Mt.
Pleasant, Pennsylvania. With seven entries, Illinois cap-
tured state honors for the most submissions. There were five
each from New York and Iowa, four from Pennsylvania,
and three each from California and Wisconsin.
The Rainbow's desire for fairness mandated that we
establish beforehand a uniform set of guidelines by which
each category would be judged. They included: I) clarity of
instructions, 2) ease of loading, 3) format, 4) vocabulary. 5)
grammar. 6) creativity. 7) enjoyment, 8) realism, 9) resolu-
tion. 10) use of color, 1 1) responsiveness, 12) use of sound,
13) level of challenge, and surprises.
Tough? They are meant to be because if you ever attempt
to market one of those gems you've created on your kitchen
table, vou'll find that the general buying public's demands
will be even harder to satisfy. Plus, if CoCo programs are
going to be used to help educate our youngsters, we as
creators must pay careful attention to such things as vocabu-
lary, grammar and spelling — not listed among the criteria
but most definitely a consideration. We also took note of
historical accuracy where appropriate, the overall educa-
tional value of an entry, and the degree of interaction that a
program allowed between the computer and its user.
Then, of course, there are the built-in prejudices that a
judge has no matter how objective he or she attempts to be in
such a situation. And there are those oh-so-subtle little
things that can make a differenpe in the quality of a pro-
gram, particularly in a simulation program.
Okay, enough sermonizing. There's no getting around the
fact that not everybody can win in a competitive situation.
So, here goes ...
Through a grueling process, which involved many reload-
ings and endless comparisons, we determined that the fol-
lowing 15 entries, which are listed in alphabetical order, are
the very best in a very healthy field. We have singled out the
best of show, the runners-up and a number of honorable
mentions:
BR ADD BALASCO of Mansfield, Massachusetts,
for Sailing.
DON BRADFORD of Solano Beach, California.
for CMl War.
RICHARD BROWN of Lorain, Ohio, for Ship of
the Line.
GREGORY CLARK of Syracuse, New York, for
Flood.
MARTIN LEE of Overland Park, Kansas, for
Baseball.
DAVID MANN of North Syracuse, New York, for
Restaurant.
GEORGE MAREK of Glastenburg. Connecticut,
for Air Traffic Controller.
F. W. McKENZIE of Saugerties, New York, for
Flight. .
GILBERT S. MURRAY of Columbus, Ohio, for
Big Business.
PAT PUGLIANO of Baden, Pennsylvania, for
Street Racer.
DAVID ROS1CKY of Pittsburgh, Pennsylvania,
for Street Racer.
GEOFF STARK of Winnepeg, Manitoba, Can-
ada, for Mars Sim.
JEFF STEVENS of Columbus. Ohio, for Con-
gress.
ROBERT K. TYSON of Jupiter, Florida, for Elec-
tion '84.
TOM WEBER of Milwaukee. Wisconsin, for War
Games.
For their efforts all of these folks will receive prizes from
the Rainbow's generous advertisers, and each of them can
expect to see their entries published in book form in the near
future.
In keeping with a Rainbow tradition that started with the
Adventure Contest winners announcement in January —
and a format that is followed in the Miss America competi-
tion _ the grand finale will come later. But first some special
awards and honorable mentions, then the runners-up, fol-
lowed by the top two winners whose programs are listed in
this month's issue.
The Up, Up And Away Award goes to F.W. (Skip)
McKenzie for Flight, a delightful program that provides a
panorama of mountains, trees and city skylines for you to
negotiate, using the arrow keys on your keyboard. Skip's
entry was fun to play and there was minimum use of confus-
ing indicators on what are usually difficult-to-read instru-
ment panels. The view from the cockpit separated this one
from the average flight simulation.
The Water Over The Bridge Award to Gregory Clark for
Flood. Due to heavy rain. Rainbow River overflows its
banks. Greg provided us with a very detailed and colorful
map in high resolution to track the river's progress, along
with timely weather forecasts and gauge readings of the
water level. The challenge was to use the floodgates, the
heavy equipment (trucks and bulldozers), the sandbags, fuel
supplies and manpower available to us to quell the ever-
constant threat.
The John Paul Jones Award goes to Richard Brown, a
freshman at Dartmouth College, for his Ship O' Line, feat-
uring sea battles as the one between the U . S. Frigate Consti-
tution and the British ship Guerrier, which almost ended the
War of 1812. A 17-page set of instructions, complete with
bibliography, will prepare you for the stiffest foe on the seas.
Separate screens allow you to keep track of your maneuvers,
and there are dozens of options available that have ob-
viously been carefully researched, lending a great deal of
authenticity to this sterling effort.
The Union Label Award to Gilbert S. Murray for Big
Business, in which you are the manufacturer of Enertabs, a
November 1983 the RAINBOW 69
new system of energy storage. Your contract is for between
six and 10 years, which are divided into quarters. You're in
competition with nine other companies, which can be
represented by CoCo or, believe it or not, nine other players
of your choosing. The program establishes a business cycle,
includes predictions about the economy and determines the
demand for your product. A good program for teaching
economics to would-be entrepreneurs.
The Sound Of Music Award goes to David Rosicky, a
young high school student, for the funeral music following
the demise of "A 1 E. Katt" who is wasted on his way home
with his paycheck. David also receives the Best Use Of
Special Effects for his title page, which features the name of
the program (Street Races) racing across the screen to put-
tering sound, and intermittent use of checkerboard pattern
that can only be described as hypnotic.
The Chapter Eleven Award goes to David Mann for
Restaurant, a simulation that has you inheriting the family
business. Your job is to run it and turn it into one of the
largest chains in the country. Hiring, firing, buying, selling
and advertising are all your responsibility. The problem 1
had was that 1 didn't know the first thing about buying food
by the pound and setting an appropriate price — so the first
10 times through I went bankrupt. You also have to pay
your employees a decent wage or they'll leave. You have a
choice of three levels of competition — corporate, partner-
ship, or entrepreneur. The opening graphic of a table set for
two was nicely done, creating the appropriate atmosphere.
The Golden Glove Award goes to Martin Lee for Base-
ball, a simulation of the seventh game of last year's World
Series between the Milwaukee Brewers and the St. Louis
Cardinals. A good baseball game for CoCo is long overdue
(so is a good basketball game for that matter) and this one is
a good start. Featuring the starting lineups in that game and
basing their hitting and pitching probabilities on their actual
averages, the game is uncannily consistent with what you
might expect in actual competition. Between each batter you
are given offensive and defensive option — and you can bet
that the Cards' Willie McGee will usually be successful in
stealing second base. I was a little suspicious when Milwau-
kee won the first five games, but then St. Louis got hot and
won the next three. There are high-scoring affairs and there
are pitchers' duels. The old favorite, "Take Me Out To The
Ballgame," is a nice touch between innings, as is the score-
board. If you like baseball, you'll enjoy this one.
The If You Walk, You're Fired Award goes to George K.
Marek for Air Traffic Control, in which you are responsible
for the safety of hundreds of air passengers. The display
provides information from radar and the ground computers
about aircraft location, speed and status. This one requires a
lot of concentration, as well as attention to the instructions,
because you can't leave anything to chance in the role you
are playing. Mid-air collisions and crash landings are com-
mon occurrences at first, but as you become accustomed to
the pace the odds improve significantly. This is a well-
conceived simulation, nicely packaged and with a lot of
potential.
Fifth Runner-Up is Bradd Belasco for Sailing, a must for
those of us who have the urge to head for the lake over the
weekend. Dividing the screen into three sections — the top
left for a side view of sail status, the top right an overhead
view of the board to show direction of the board, the boom
and the rudder, and bottom half of the screen to display the
navigational course. Using your joystick to determine the
proper setting, you must make it to the other side of the lake
and dock safely. If you make a mistake, the graphic changes
70 the RAINBOW November 1983
to a sinking sailboat and a man treading water. You are
given a danger signal if you place the boom in such a
position that the wind will cause to quickly swing around
and send you sailing like an opening kickoff, but you're also
given lime to respond. Bradd kept this simple and easy to
understand, with exceptional graphics. A fun learning
experience.
Fourth Runner-Up is Pat Pugliano for Life With CoCo, a
simulation with which many Rainbow readers can readily
identify. It's about a computer programmer who is trying to
make it big by creating games and writing articles for com-
puter magazines. But first he has to learn assembly language
and build up his inventory of equipment. Like many of us he
reads the ads to keep up with sales on software. He visits a
computer store and. if he has used his money wisely, he
purchases a utility program. The real problem for our hero is
that there are only so many hours in the day for him to do his
regular job, read computer magazines, work on his pro-
grams and articles. Sometimes he neglects his diet and his
sleep because he is so attached to CoCo. If he manages his
time, health and money wisely, he is a tremendous success
and all of us are buying his programs.
Third Runner-Up is Don Bradford for Civil War, a situa-
tion in which you are commander of the entire Southern
Army, reporting directly to Jefferson Davis, President of the
Confederacy. This game is loaded with options, multiple
choices and a nice map of the North and South pinpointing
the battle in which you are currently engaged. You receive
your instructions from the President via telegram which is
transmitted staccato style across the screen, telling you
where to do battle next. Before the battle, however, you are
required to submit a formal budget to the President. Unless
you go in the red. he will usually approve it. You are given
six options for the battle plan (including the ability to sur-
render the battle or to give up the war). Just before entering
the skirmish, you will usually receive a report from your
spies, unless they have been captured. After the battle, you
are given a report of casualties, desertions, prisoners-of-war
and whether you won or lost. You also can see a record of all
battles. After I3 battles, a winner is declared (usually the
North since CoCo is its commander). If you lose, you must
unconditionally surrender all of your territories, admit your
guilt and wrong-doing, be tried as a war criminal, and
hanged! Great fun and a good review of this historic period.
Second Runner-Up is Geoff Stark for Mars Sim. Geoff, a
15-year-old student, has done a tremendous job of creating
an action-packed simulation that allows you to do a visual
scan of the planet's surface, unless you land at night, at the
beginning. There are different directions and entirely differ-
ent views. Next, you are able to maneuver a robotic arm that
enables you to scoop up samples and return them to the lab
for examination. In the lab, expose the sample to oxygen.
Earth light, heat, and water to determine whether life exists.
A diagnostic function lets you check all of the systems
aboard the ship. Another option allows you to drill up to 1 .5
meters testing the planet's interior. Geoff's documentation is
extensive and indicates just how rapidly some students have
advanced in programming. Take a bow, Geoff, and stay
with CoCo because we're expecting even better things from
you.
First Runner-Up is Jeff Stevens for Congress. A high
school social studies teacher. Jeff uses this program in a
government course to show how a bill passes through Con-
gress and becomes law. It opens with a Presidential Applica-
tion, complete with dotted lines, which you must complete
to assume the office. Your object is to go down in history as a

QUALITY PROGRAMS SOLICITED
great President (sound familiar?) and your ability to get
your programs passed through Congress with a minimum
number of amendments and special favors will determine
how effective you will be. You are given two options for
major programs, which are strikingly similar to the ap-
proaches taken by recent Democratic and Republican can-
didates. The song, "Hail to the Chief," opens the game and
you're treated to other patriotic tunes when a bill passes
both houses. The visual effects are enhanced by digital coun-
ters which keep track of "yes" and "no" votes. When the bill
reaches your desk, Mr. President, you have the option of
veto (because of undesirable amendments), signing it into
law, or letting it take effect without your signature. Then,
you go on to another major priority of your administration,
following the same steps. You have only a limited time, of
course, to get your program through Congress and your
eventual stature depends upon your ability to get all your
programs passed during one term. A warning to Republi-
cans: both the House and Senate are usually heavily loaded
with Democrats, so you will experience a lot of problems. A
Gallup Poll is taken after your term and. if you do poorly,
you will probably be as popular as Herbert Hoover after the
stock market crash. On the other hand, you may be com-
pared to Franklin D. Roosevelt. This one was among the
most fun to play, while being very educational. Jeff Stevens'
government classes must be in great demand!
And now for the Best of Show, the Grand Prize winners in
the Graphic and Non-Graphic categories!
Graphics Best Of Show goes to Tom Weber, a freshman at
Marquette University, for War Game, a totally involving
simulation, which makes the movie by a similar name seen
rather tame. Tom plans to major in computer science at

Marquette and, judging from his entry, will put the school
on the map for something other than its basketball team
(sorry Marquette, but being a Louisville fan, I couldn't resist
the dig).
Tom says he is self-taught in many aspects of computer
programming. He is quite active in CoCo-MUG — the
Color Computer Milwaukee Users' Group — in which he
serves as a member of the Executive Committee.
He obviously knows what he is doing when he sits down in
front of his CoCo because War Game is a highly sophisti-
cated undertaking, which has been assembled in a relatively
short period of time since the smash-hit movie started mak-
ing its rounds.
While the subject of his simulation is rather gruesome, it's
no secret that computer war games hold immense fascina-
tion for the majority of us whether we want to admit it or
not. Tom's program, which loads in four parts, is, as far as
the judges can tell, a realistic version of what can happen
when and if some misguided power monger gives the com-
mand to start pushing buttons. It ranks high as an educa-
tional tool in that respect, as well as in loading complicated
programs — so please pay close attention to the loading
instructions after you have typed in the program. He says
that it will not run on disk because of memory requirements
— but that's never discouraged some CoCo users we all
know. Tom, you're a winner. Good luck at Marquette, and
keep those contributions coming to the Rainbow.
Non-Graphics Best of Show And Grand Prize goes to Dr.
Bob Tyson for Election 84. a simulation depicting the last
100 days of next year's presidential campaign. If the name
Bob Tyson rings a bell, it's because he's the same person who
created Strategy Football, which appeared in the Rainbow's
August issue. Bob is a Senior Systems Engineer at United
Technologies Research Center in West Palm Beach. Flor-
ida, where he works on high energy laser beam control
system development for use in defense and communication
systems by our country's armed forces.
He started doing the winning program featured in this
issue "because 1 wanted to do something that was relevant
and timely, and because I have always had a fascination for
politics." Bob also says he developed a hurricane tracking
system a few years back for his CoCo, a program which
undoubtedly would have great utility in Florida.
He's a graduate of Penn State University, where he prob-
ably picked up some of the finer points of the game of
football that were used in his August simulation. He also
learned Fortran at Penn State, a skill that he says served him
well in the Navy, and in development of the obviously strong
skills demonstrated in his latest effort. Bob says his wife Sue
was a great help in Election 84. although she was never able
to sit down in front of the computer. "She has her hands full
taking care of our five-year-old daughter Kia and two-year-
old son Andy," he notes.
Bob says he has been playing around with the idea of
doing a simulation on the 1984 Olympics. We hope he does
such a program because Bob obviously knows what he's
doing and we'd like to be able to share another of his
programs with our readers.
You will enjoy Election '84 because it includes all of the
aspects that make Presidential campaigns so fascinating.
And the suspense as the popular and electoral votes are
being tabulated will make all of the time that you have spent
typing in this great simulation well worth every minute. We
think you'll agree that Election '84 is among the best in the
field. _

Simulation Contest Non-Graphics Best of Show and Grand Prize Winner
And the winner is . . .
■ 7 lection V4 is a simulation of the
M"j 1984 presidential election cam-
m J paign. The simulation is per-
formed (played) by one or two persons
representing the Democratic and Re-
publican parties. In the one-player sim-
ulation, the computer will handle the
affairs of the opposition party.
Election '84 allows each player (the
campaign manager) to handle his or her
candidate's affairs during the campaign.
The campaign begins with 100 days left
before the election. A candidate can
travel to different states and campaign;
he can advertise in any of the states; he
can challenge his opponent to a debate;
he can raise funds for further campaign-
ing; or he can yield his position (and just
rest where he is). At any period where
the above options are presented, a cam-
paign manager can check his "intelli-
gence" and find the latest Gallup Poll
readings, the latest news reports, and
information about travel history of all
of the candidates. Each campaign man-
ager controls both his presidential and
vice-presidential candidates separately.
At the end of the campaign, on election
day, the campaign managers just sit
back and watch the election returns roll
in from all across the country. A tally of
popular and electoral votes is kept, and
before long, there is a new man in the
White House. Then you can figure out
where you went wrong, or pack your
bags for the staff job you earned. Maybe
President Reagan is reelected; it's up to
you.
Simulation: The campaign begins with

in physics and designs and ana-
lyzes high energy laser beam con-
trol systems using computer simu-
lations. He and his family live in
Jupiter, Florida.)
your choice of a long or short campaign
and then the selection of the candidates.
Choose the short campaign for the first
time through, the longer one for more
realism. Even if only one player is
involved, all four candidates (two presi-
dential and two vice-presidential) must
be chosen. The program gives six possi-
ble candidates for the positions on the
ticket from each party. These are the
most likely candidates from events this
summer (1983). Points for financial
strength, experience, and charisma are
assigned. Changes can be made if events
change between now and the summer of
"84. (See below for program descrip-
tion). After candidate selection, the cam-
paign begins with alternating turns from
the four candidates. If the computer is
handling the affairs of one party, deci-
sions will be made very quickly, but
some require your reply, so watch care-
fully.
If you have to make the decisions, just
follow the menu. This is where the fun
comes in. If you want to find out where
everybody has been, just hit "I" for intel-
ligence. You will see a screen display
with the two letter identification for
each of the 50 states and Washington.
D.C. (yes, Washington D.C. has three
electoral votes). Beside the state i.d. is

its electoral votes. Also alongside, you
may see either blue or red graphics
characters. If the upper red is colored in,
then the Democratic presidential can-
didate has been there; if the color ap-
pears in the lower red block, then the
Democratic vice-presidential candidate
has been there. If the upper block is
blue, the Republican presidential can-
didate has visited, and if the lower block
is blue the visit was by the Republican
Vice-Presidential candidate. Get it?
Democratic party is red; Republicans
are blue. Upper is Presidential; lower is
Vice-Presidential.
If you continue, you will get the cur-
rent Gallup Poll for the election. Re-
member, the Poll only tells popular vote
count; it takes electoral votes to win the
election, so use the "intelligence" fea-
ture whenever necessary (or just to find
out a state's identification). Oh yes, the
latest news report may be of interest.
Read it carefully and act accordingly.
You can also campaign in any state.
Just press T' for travel and follow the
prompts. Travel costs money, so be
thrifty unless you're on an all-out blitz
near the finish. You do not need to
travel to pick up votes. You can press
'A' and advertise in any state. This costs
a lot of money, but it's well worth it.
Many votes can be had for a few TV
commercials. When your total cam-
paign treasury total is below zero, you
will be forced to raise money. This may
be at an inopportune time, so you may
want to raise money early in the cam-
paign. If your total goes negative near
the end of the campaign, that's okay,
since everybody goes into debt running
for the Presidency. You and your credi-
tors will hope that you can pay it back.
If you press 'Y' and yield, you will
pick up more votes wherever you are.
It's a good rest. A high risk, but high
payoff, option is the debate, 'D.' You
can pick up thousands or millions of
votes across the country by just this one
event. But be careful, a debate must be
accepted by your opponent and one slip
of the tongue could ruin your chances.
When election day arrives, just sit
back and watch. You may be sorely dis-
appointed as your candidate loses tough
states by a few votes. But then again you
may be overjoyed when he wins by a
landslide.
How the program works: Setup takes
place in lines 5 — 102 with calls to sub-
routines to run the logo, the candidate
selections, etc. A large iterative loop
extends from 200—340 where the bulk
of the simulation is run. Subroutine
7800 creates the displays for the option
selections. The arrays dimensioned in
lines 10 and 1 1 hold the state identifiers
(S$), the votes cast, VT, the visits, VS,
the candidate strengths, SR, and the
money, MY. The other variables are
flags and codes to keep track of where
the simulation is and where it hasn't
been.
Changes can be made to update the
simulation. 4500 — 460 1 contain the news
stories. 8010— 801 1 contain the Demo-
cratic candidates and 8050 — 8052 con-
tain the Republicans. If you change the

Simulation Contest Graphics Best of Show
90 tht RAINBOW November 1983
by Thomas G. Welier
I
|1 he idea for this simulation came from
the movie "WarGames" which was
about a high school student who taps
into the United States defense computer,
and by doing so, almost starts World War
III.
In this simulation, you are in control of
the NORth American Defense (NORAD)
facility, and are required to take part in a
simulation of a thermonuclear war between
the U.S. and Russia. Both countries have 10
bases. The country to lose all 10 of its bases
first loses the simulation. No matter which
side loses first, though, chances are that the
other side wouldn't do much better, due to
the damage done to its country.
In WarGame, you'll have eight com-
mands you can enter: USCON, SOVCON,
JAM, SUBS?, DESUB, LAUNCH, TIME?
and ?, which prints out the previous list.
Every command except ? must be ended
with a carriage return in order to be acted
upon.
USCON prints out the condition of the
United States in terms of estimated kill
ratio, and bases remaining.
SOVCON does the same thing as USCON
except using data concerning the Soviet
Union.
JAM will jam Russia's launch code for a
short time, during which they cannot launch
any missiles from their bases, other than one
which may already be in the air (it should be
noted that Russia can do the same thing to
you).
SUBS? will detect any enemy subs near
the Pacific coast.
DESUB is a special mode you enter to
destroy these subs. It is important that this
be done, since these vessels launch missiles
at your bases as frequently as, or more so
than, the Soviet bases do. Even though
knocking out the subs will save your bases
from destruction, it will not affect the num-
ber of bases you have to get. Along the same
lines, you don't have to get any of the subs to
conclude the simulation . . . just the bases.
When you enter the sub destroy mode, a
flashing dot will appear in the center of the
larger map of the United States. You can
move the dot around anywhere within the
boundary of this map. The idea is to position
it near the center of a submarine using the
four arrow keys. When you hit the "kill
spot" on a sub, you get a pulsing tone, telling
you to launch the missile (by hitting [EN-
TER]). Make sure that before you launch,
you hear the tone at least twice with your
fingers off the arrow keys. This assures that
the sub will really be destroyed, rather than a
near-miss. Once you've launched a missile in
this mode, your flashing dot will return to
where it started. You can now either go get
another sub, or return to the regular corn-

to them:
Soviet Bases:
1) Moscow
2) Leningrad
3) Kharkov
4) Volograd
5) Rostov
6) Archangel
7) Yakutsk
8) Kamchatka
9) Vladivostok
10) Minsk
mand mode by hitting [BREAK]. You
can also return at any time while in the
DESUB mode by hitting [BREAK].
Launch — the syntax for this com-
mand is "LAUNCHx-y," where x is the
number corresponding to the U.S. base
launch site, and y is the number corres-
ponding to the Soviet base target. (Don't
forget the "-" in between them.)
TIME? will tell you, in real time, the
"game time elapsed"and the "estimated
time remaining" in the simulation.
Not all the missiles launched by one
or the other side will make it all the way
to their destinations. Occasionally, a
missile may fail to launch at the launch
site or malfunction in midflight. Neither
of these indicate that the launch site
base will not launch future warheads
correctly, but rather indicate a fault
with the individual missile.
Usually this simulation is completed
within five to 10 minutes, so think and
act quickly; and Good Luck, General . . .
Here are the names of all the bases,
along with the numbers corresponding
U.S. Bases:
1) Nome
2) Fairbanks
3) San Francisco
4) San Diego
5) Spokane
6) Denver
7) Houston
8) Charleston
9) Chicago
10) Seattle
Loading Procedures
Using an Editor/ Assembler like Ra-
dio Shack's EDTASM+, type in the
program called PART 1 . This routine is
similar to that used in the "Micro-
Meltdown" article {Rainbow, April
1983), to allow the player to type in
Hi-Res, but contains a different char-
acter-set, and contains a few other ML
routines.
PART 2, which draws the NORAD
war room scene, takes a long time to
load and run, so for this reason, after
completing its picture, it saves it out to
tape as a ML file which is then loaded
back in with a CLOADM command.
The picture loads and is ready to go
much faster than it took to load and run
PART 2, so after you have saved its ML
file, you can kill the BASIC program if
desired.
PART 3 is the instruction program. It
gives a brief description of what you
must do, and also will help you to match
the base numbers to their locations.
This program will automatically load in
the next one.
PART 4 is the actual simulation part
of the program, and, like PART 2, takes
awhile to load. When PART 3 has fin-
ished loading PART 4, you'll see an
"OK" prompt in the lower left corner of
the screen. You can type RUN and
[ENTER], then the war is on . . .
Editor's Note: WarGame uses a speed-
up poke in Lines 40 and 101. If your
computer will not accept the speed-up
poke, remove POKE 65495,0 from these
lines.)

RMS is a complete DATABASE MANAGEMENT package
for the 6809 computer. It is made up of five machine
language programs that make up the most powerful
business programming tool available for the 6809. It can be
used by the relative novice, to implement an incredible
variety of information storage and retrieval applications,
without any programming. However, the programmer can
use RMS as pan of the solution to a larger problem, saving
many hours of unnecessary program development time.
RMS can be used to handle data input, editing, validation,
on-line retrieval, sorting and printed reports. Custom data
manipulation can be filled in by the user's BASIC programs.

FINE PRODUCTS FOR THE COLOR COMPUTER AND TDP-100
Coco-Accountant II
We've turned a fine accounting program into a great
accounting program for the home or small business.
The all-new Coco-Accountant II provides everything
you need to keep track of your finances and make
income tax time a breeze. Spend a few minutes every
month with your canceled checks, credit card bills,
cash receipts and payroll stubs. Data entry is quick and
painless. When you're through, Coco-Accountant II will
list and total expenditures and income by month,
account or payee, provide a year-to-date summary by
account and figure your net cash flow. Better yet, it will
provide a printed spreadsheet to show your year at a
glance.
The program sorts entries by date, lists most func-
tions to screen or printer and saves your files to tape or
disk. A special feature flags tax deductible expenses
and expenses subject to state sales tax. It even com-
putes the sales tax you paid. In addition, COCO-
ACCOUNTANT II includes a separate program to bal-
ance your checkbook the easy way and print a
reconciliation statement. Up to 450 entries per file on
32K tape version, 500 per file on 32K disk and 750 on
64K disk version. For 16K Coco owners we have a
simpler program that tracks expenses only, without the
tax options. It will handle 200 entries per file. All ver-
sions are easy to use and menu-driven and come with
complete documentation. And here's the best part —
the price! Coco-Acountant II is only S21.95 on tape,
$24.95 on disk.
!
Play Blackjaq!
This is as close as you can come to the real thing
without losing your shirt! A full casino simulation, with
up to 5 players and 9 decks. The computer plays vacant
hands by card counting rules, keeps track of every-
body's winnings and losings, displays two card-
counting algorithms and even prints out the results of
every hand if a printer is on line!. Great for the beginner
or experienced player. Use it at home for fun or brush
up on your technique before hitting Atlantic City or Las
Vegas. Requires 16K Ext. Bas. Only S19.95 on tape,
S24.95 on disk.
Kokomath!
Teachers and parents: Are your kids bored by dull
educational programs? Let KOKO the Math Clown
make arithmetic a joy. KOKO gives your youngsters 10
math problems. If they get them all right, they give
KOKO a bath! He keeps track of their score. Add, sub-
tract, multiply an divide at three levels of difficulty.
Colorful graphics and music make this a kid-tested
winner! Includes both Extended and Standard Basic
Versions. Only $8.95
To order programs, send check or money order to
FEDERAL HILL SOFTWARE, 825 William St., Balti-
more, MD 21 230. Your personal check is welcome— no
delays. Add S1 .50 per order for postage and handling.
64K Breakthrough!
Did you feel gypped when you found out your "64K"
computer still had the same old 32K in Basic? We sure
did. So we've developed HID 'N RAM, a program that
will access that "hidden" 32Kfrom Basic and use it for
data storage. Imagine writing a 28K data handling pro-
gram with every bell and whistle you can think up and
still having 32K left for the names, numbers and ad-
dresses you're crunching! HID 'N RAM is a brief ML
driver embedded in a Basic demonstration program (a
mailing list) that shows you how to store your data in
the "other" 32K and access it using regular Basic com-
mands. When you see how it works, you can delete our
program and write your own. The ML driver stays with
the program! Use it from tape or disk. What's the
catch? There's only one. Your data must be in strings of
equal length — which the program takes care of — and
that length must be a power of 2 (such as 8, 1 6, 32, 64 or
128 bytes). Of course, you must have a 64K computer.
Comes with complete documentation. HID 'N RAM is
onlv $19.95 on tape, $24.95 on disk.
The Handicapper
Use the power of you Color Computer to im-
prove your performance at the track! The Handicapper
is two separate programs for thoroughbred and har-
ness horses that apply sound handicapping tech-
niques to produce rankings for the horses in each
race. Factors include speed, distance, track condition,
post position, past performance, jockey or driver's
record and other attributes. With a little practice, you
can handicap an entire race in a few minutes and a
whole card in less than an hour! Easy enough for the
beginner, sophisticated enough for the veteran horse-
player. Cassette comes with both Extended and Stan-
dard Basic versions. Includes complete documenta-
tion and betting guide. Thoughred or Harness Hand-
icapper, $24.95 each on tape. S29.95 disk. Both pro-
grams only $39.95 tape or disk.
Printer Artist
This unique printer utility introduces the Color Com-
puter to the little known but delightful craft called
"Artyping." This is the art of creating pictures using
typewritten characters, and Printer Artist puts it at your
fingertips. It includes two programs with 12 ready-to-
run drawings of of ships, birds and animals, holiday
and patriotic themes, famous Americans and more. In
addition, there are two utility programs and in-
structions for 40 additional drawings. Create your own
file of printer art and save it to tape or disk. Complete
documentation. Fun for home or classroom. Only
$19.95 on tape, $24.95 on disk. Requires Ext. Bas.

By Michael Plog, Ph.D.
Rainbow Contributing Editor
The impact of microcomputers on the educational
scene presents several unusual features. Some are
downright weird. It is not stretching truth or credibil-
ity too much to say that a real revolution is underway. We
won't know the full impact of this revolution for a few years
yet, but it is easy to tell that changes are happening now.
Well, what are some of these features?
First, it is no secret that many students are much more
knowledgeable about microcomputers than most teachers.
This reversal of roles is completely new in the educational
arena. Never before, as far as 1 know, has a field of study
appeared so important to the nation's schools, with the
adults in those schools having less knowledge than students.
No matter what you may think about teachers you had (or
have), this is definitely not normal. Math teachers have
always known more about mathematics than students being
taught. The same holds true for teachers of English, the
social sciences, and physical sciences. Even in the less tradi-
tional courses taught in schools, teachers have almost
always started with more knowledge than students.
In many schools around the country, students with
microcomputers in their homes were asked to help set up
courses and computer labs. Often students provided teacher
with a "first lesson" in microcomputers.
Ah, this is just a passing phase of the computer revolution
in education; the situation cannot last for very long. Now.
notice, 1 was talking a bout knowledge of the subject matter.
That is different than talking about the ability to learn
something, or the intelligence involved. The unbalanced
situation of students' knowledge beinggreater than teachers'
will soon pass away — because of the nature of teachers.
(Michael Plug received his Ph. D. degree from the
University of Illinois, the M.S. from Memphis State
University, and the B.S.from the University of Ten-
nessee. For his foreign/ 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.)
Teachers are a strange breed; they return to school them-
selves, and appear to never tire of learning. After all, educa-
tion is their way of life, their reason for existence, their base
of personal satisfaction and self-image. Have no doubts
about it; the next few summers (plus this last one) will see a
large number of teachers returning to state universities for

courses in computers. I was in a discussion with a man (over
40 years old) talking about his 12-year-old son. The man
commented casually, "Jeff took a BASIC course this summer.
So did I." All over the country, expect to see teachers
pouring over textbooks they would never have noticed a few
years ago.
This means the students of the future will come to school
at age five, knowing less about computers than the teachers.
(Teachers do know how to study.) For the present, however,
we are stuck with an unusual situation.
There is another passing phase in the computer revolution
worth mentioning here. There is a different type of person
interested in micro applications in schools now than in the
past. Let me tell you a story about a man who is a perfect
example of the past type of micro/ education. About seven
or eight years ago, I worked for a school district. I heard
about a sixth grade teacher in the district who had an
interest in microcomputers. He even purchases a kit and
built a computer. It had few applications, of course, but he
was an electronic nut. His kit ended up in his classroom,
where the students promptly discovered the power of

humans over machinery. A few years later, I was in a differ-
ent job, and again heard about this fellow. He now was
director of a consortium of schools, with the task of imple-
menting microcomputer education in several districts.
It used to be the case that only one type of person was
interested in educational microcomputer applications. We
all know thay type of person. Typically male (why?), inter-
ested in electronics, wanted to poke around inside machines,
enjoyed Adventure games, and was often a member of some
futurist organization. When these people buy Color Com-
puters, the first thing they do is take off the case and play
with the internal parts. Now, however, the situation is for
teachers to learn from; and some may be technicians. It is,
however, impossible to replace a teacher in education.
Today, the typical administrator considering putting
microcomputers in schools is a lot different from the elec-
tronic nut. I have heard several superintendents comment
that they did not understand microcomputers, did not like
them, never wanted to touch one, even admit they were
afraid of computers; but know they had to have the ma-
chines. They realized that without some background in
microcomputers, their students would be unable to cope in
tomorrow's world.
This change of potential educational market may have
greater import than we realize. Naturally, the early interest
people will continue to expand their microcomputer uses in
schools — both in types of applications and number of
machines available to students. But the late-comers are
more numerous, and represent a different type of market. It
would be interesting to see the outcomes of each type of
school administrator: attitudes of students toward micro-
computers, educational applications of the technology,
types of machines purchased, etc. I'm sure someone will do
such a study in a few years.
There is one last change, another passing phase, in educa-
tional uses of microcomputers to be discussed here. When
microcomputers were first being used in school, a common
fear was expressed — that teachers would be replaced by
machines. Yes, you and 1 know that is pure bunk, but people
who do not understand either education or microcomputers
had said it. If anything, the use of microcomputers will mean
more educational professionals, not less. Now, some of
these professionals may not be teachers. Some will be devel-
opers of computer curriculum; some will be resource people
for teachers to learn from; and some may be technicians. It
is, however, impossible to replace a teacher in education.
Unlike the other two passing phases in the educational
computer revolution — type of school people using micros
and knowledge level of students compared with adults —
this phase is not yet occurring. There is still uncertainty,
maybe even fear, in the schools.
A few years from now, this situation will have changed. It
is out responsibility to help that change happen. After all, if
you have read this far, you must be a computer evangelist.
Keep it up, those who will become reluctant converts still
need you.
Before I sign off for this month, 1 want to thank all of you
who have written me. I appreciate hearing from you. I'm
looking forward to the software evaluation process begun in
September. (If you do not know what I'm talking about, dig
out your September issue.) It will take several months before
anything is reported, but keep mailing those forms.
Until next month, keep thinking education. As long as
you keep learning, you may grow up, but you'll never grow
old.

7- -A
Remote Operation
Of The Color Computer
By Dan Downard
Rainbow Technical Editor
I guess that the first experience that I had with computers
was in school when everyone had to stand in line for
hours just to use the keypunch. After you labored over
the magic keys for a few hours, you were ready for the acid
test. Usually a tray for student projects was situated at the
entrance to the computer room. You would place your card
deck and the programs would place your card deck and the
programs would be run on a first-come, first-served basis,
sometimes at night when business use was at a minimum.
The first computer 1 remember was an IBM mainframe with
all kinds of flashing lights and switches. It occupied a large
room in the basement of the administration building. Other
than an operator's console, all input and output was
accomplished by punched cards and a printer. My, if they
could only see me now.
I guess the only real difference, besides price and state-of-
the-art changes, is remote control and time sharing which at
that time were very expensive and in their infancy. At the
same time, present technology allows home computers with
the power of those old mainframes and, with the advent of
OS-9, you can now use the CoCo for time sharing and
remote operation. In this same issue the Rainbow is giving
you a bulletin board if you are interested in remote opera-
tion of the CoCo. One of the most important aspects of
BBS's is the driver routine. This is the link between your
computer and the outside world. To be more specific your
Serial I/O, or RS-232 port as we like to call it, is your
communications link to printers, modems, ham radio, etc.
In this article, we will examine the three major operating
systems for the CoCo, Disk BASIC, FLEX and OS-9. and
examine the ways to use remote terminals, whether they be
direct connected or by use of a modem. As you are probably
aware, FLEX and OS-9 already contain software for remote
I/O but what about Disk BASIC? A very short program
called Remote is included to allow elementary remote con-
trol of the CoCo.
In addition to your CoCo, you will need a terminal, or
(Dan Downard is an electrical engineer and has been
involved in electronics/or 24 years through ham radio
(K4KVVT). His interest in computers began about five
years ago and he has built several 68 XX systems.)
remote computer, whether it be another CoCo, and MCIO,
Model 100 — anything that has a screen and a keyboard,
and a modem. Even the modem is not required if you wish to
direct connect the terminal. The remote terminal must have
software to translate keystrokes into serial output signals
and remote input signals to the screen. Several commercial
pieces of software are available such as Super "Color" Ter-
minal, "Colorcom/E. "and "Videotex. "What we are inter-
ested in doing is the exact opposite of a terminal. We wish to
replace the keyboard with a remote signal and reroute out-
put from the screen to the RS-232 port.
Disk BASIC
First, several commercial programs are available allowing
remote operation of the CoCo. A few that come to mind are
Remoterm by Star Kits; RTD3.0, by Ed March; and RTD28.
by Lee Blitch. All have many features besides driver rou-
tines. Why do you need a program like this in the first place?
The three programs mentioned above are synonymous with
bulletin boards. As we all know, BBS's are becoming a great
medium of information exchange regarding computers.
Why not start your own?
On the other hand, there are several other uses for remote
operation of the CoCo. Serious word processing requires
more than a 32-, 5 1 - or 64- character screen. How about that
budget too? How many of us can afford to have two com-
plete computers with disk drives, etc. With a remote termi-
nal, you can have one complete system and one bare-bones
terminal to effectively give you two computers. Model 100
owners can have a disk system before they are marketed.
Listing I is an elementary remote terminal driver for the
CoCo. It allows both local and remote operation of the
CoCo. Local I/O is obviously the keyboard and moni-
tor(TV). All output to the screen is also sent at 300 Baud to
the Serial I/O port. Input can either be from the keyboard or
a 300 Baud signal from the port. No frills or bells and
whistles are included in this version. If you have a serious
application I would recommend one of the above commer-
cial drivers. Remote should provide you with a method of
experimentation with a remote terminal.
Running Remote
Remote is written in PIC (position independent code) and
118
the RAINBOW November 1 983
will execute anywhere in memory. To input Remote the first
time, use a monitor such as ZBUG or an assembler such as
EDTASM+.
With ZBUG, enter the object code one byte at a time at
your selected address. The listing is assembled at S3F00. A
typical session would appear as follows with [E] meaning
[ENTER] and [DA] meaning Down Arrow:
Z[E] Enter ZBUG tromEDTASM+
B[E] Enter byte mode
3F00/ Open memory at address S3F00
BE[DA] Store $BE at S3F00 and increment address
01 [DA] Store $01 at S3 F01
68[DA] Store $68 at S3 F02
After the program is in memory, save it to tape before you
run it using the ZBUG P command for the listing given,
S3F00 is the start and execute address. Exit ZBUG and
CLOADM the program from BASIC. Type EXEC and you
are in the remote mode.
FLEX
A remote terminal driver is built-in to Frank Hogg FLEX
5.0:4. It is called the EXT command. At any FLEX +++
prompt you simply type EXT,[hex 1],. . . ,[hex n] [E] and
you have it made. [Hex 1] thru [hex n] are hex numbers sent
to change the preset values for terminal parameters such as
delay after from feed, delay between characters, etc. A com-
plete description of this command is given in the Flex
manual,
rate of the external terminal.
A typical remote initialization of FLEX would appear as
follows:
+++SETUP PB300<E>
+++EXT„„2, 1 B.6 1 ,2, 1 B,60<E>
The first command sets the Baud rate at 300. The next
command enables the remote driver. The hex string 2, IB,
6 1 ,2, 1 B,60 are codes to turn off and on a printer attached to
the terminal. This is a very nice feature of FLEX since more
elaborate terminals also have a printer port.
OS9
I hated to save the best until last, but OS-9 is designed for
remote operation. The previous operating systems are capa-
ble of remote access with one limitation: Only one program
and task can run at a time. Since OS-9 is both multi-user and
multi-tasking, you can now think of your CoCo as a main-
frame. While you are using BASIC09 from the keyboard
one of your buddies can run PA S CAL from a remote termi-
nal. Sounds unreal, doesn't it? Well, it's really simple. OS9
has three commands that affect remote operation. TSMON
is the command that implements time-sharing, or time-
sharing monitor. LOGIN provides a security system for
logging on the CoCo by remote users. XMODE provides
initialization for non standard terminals.
First, let us take a look at the LOGIN command. LOGIN
requests a user name and password, which it checks against
a validation file named "password." The system notation of
the password file is /DO/ SYS/ password. A typical line in
this file would appear as:
DAN DOWNARD,REMOTE,l,l,/DO/CMDS,/DI/DP
D.SHELL
From left to right the codes stand for user, password, user
ID, priority, pathlist of initial execution directory, pathlist
of initial data directory and the name of the initial program
to execute. In addition to LOG I N , each file in the system has
attributes to protect against public access if you so desire.
With XMODE, you can control the characteristics of the
remote terminal, or to put it in proper perpective, you can
initialize output to the remote terminal to match its parame-
ters. The following parameters are initialized to default
values but can be changed if desired:
upc
bsb
bsl
echo
If
pause
null

bsp

The Baud rate has a range of 1 10 to 19200. Tl is the device
number of the RS-232 port, so a line to initialize the remote
terminal at 300 Baud and generate line feeds would appear
as:
OS9:XMODE/Tl baud=l If
Finally we have TSMON. Assuming you can use default
values for the above commands, all you really have to do to
activate the timesharing monitor is type "TSMON ,'TI&."
The ampersand (&) is a modifier for concurrent execution.
Any XMODE or LOGIN changes should be made before
TSMON is activated, but as long as the Baud rate is correct.
XMODE can be accessed by the remote user if you have
given him access to that command.
All of the OS-9 commands are well documented in the
Radio Shack manual including the above three. At the sake
of repeating myself, OS-9 is designed for remote operation,
one of the reasons it is such a popular operating system for
small computers.

Hardware
One of the most difficult tasks facing you will be making
an interface cable between your CoCo's RS-232 port and the
remote terminal or modem. A few hints are in order. For
RS-232 operation the serial I/O pinout is defined as follows:
CoCo
Pin 1
Pin 2
Pin 3
Pin 4
Description
Carrier Detect
RS-232 IN
Signal Ground
RS-232 OUT
RS-232(25 Pin)
**
Pin 2
Pin 7
Pin 3
Jumpers may be required on the RS-232 connector. For a
start, try shorting Pin 4 to 5 and Pins 6,8, and 20. If this fails,
try to obtain assistance from a manual or from the
manufacturer.
Summary
Remote operation of the CoCo is a reality for whatever
reason you desire. Personally. I have always dreamed of
connecting my ham radio to a modem under computer
control and carrying on a QSO (contact) from my office at
lunch. It's getting closer to reality. 1 still like to check into
bulletin boards and see what's going on, but you might say
that OS-9 will make them obsolete, but who knows? By the
way, assuming you have enough disk space to initialize
users, OS-9 will only accept 65535. Any more than that and
you're out of luck.

COMMUNICATIONS
Teach CoCo To
Dial Up Some Fun
By Ric Manning
There's a device you can plug into your computer that
can deliver free software, computer games, loads of
technical advice and information and perhaps even a
date for Saturday night.
The device is called a modem and when it's matched with a
terminal program and your Color Computer, it becomes
your passport to a world of fun and information. But be
careful. Data-tripping can be addictive and a computer can
be like a teenager — once you teach it to use the telephone,
it's hard to get it off.
More than 1 ,000 other computers around the country are
out there waiting for yours to dial up for a chat. A growing
number of bulletin boards are run on Color Computers and
dozens of others are loaded with information, merchandise
and fun things to read about and do.
Here are just a few examples:
• The Mines of Moria bulletin board in Houston
(713-871-8577) contains 17 tutorials that give you
step-by-step instructions for solving some of the
most popular adventure games.
• Callers who dial up Dickinson's Movie Guide
near Kansas City (913-432-5544) can get a brief
review of the movies playing in the Kansas City area
along with a list of the stars and a synopsis of the
plots.
• The Fantasy Plaza in Burbank, Calif., (213-244-
1 100) is a computer set up like a large department
store. Callers can shop for hardware and software
(including CoCo products), videogame cartridges,
health and beauty aids and even kitchen products.
• The Big Top Games system in Milwaukee (414-
259-9475) lets you play any of about 20 games while
you're connected.
• The flagship of the Dial-Your-Match system in
Burbank, Calif., (213-842-3322) is an electronic
(Ric Manning is the editor of Plumb, a newsletter that
covers news and features about specially bulletin
boards and computer communications services. A
five-issue subscription is $20 from Plumb, Box 300,
Harrods Creek, Ky.. 40027.)
matchmaker on which computer nuts can meet and
get to know each other.
Best of all, most of the computer bulletin board systems
around the country contain a library of free programs that
can be transmitted directly to your computer.
A good example is Dr. D's CoCo Corner run by Gary
Dunsford in Pensacola, Fla. (904^56-7195). The system
contains 15 programs including a disk utility, copy pro-
grams, several games such as Missile Command and Saucer
and programs for creating graphic displays.
Plugging In
So how do you find a seat at this banquet table of compu-
ter goodies?
First you need a modem. That's shorthand for modulator-
demodulator, a device that translates the digital signal put
out by a computer into an analog signal that can be carried
by telephone lines. For the Color Computer, any modem
that plugs into an RS232 port will do.
Also, you'll need a program that tells your computer to
act like a terminal — an extension of the computer you call.
Some of the more popular terminal programs for the
Color Computer are Colorcom/E, which is available on
disk or ROM pack for about $50, and Nelson's Super Color
Terminal, available on tape, disk or ROM pack for $50 to
$70. Others include Color Term Plus, Autoterm, DFT II
and Videotex.
And, of course, you'll need a telephone. The garden var-
iety phone will do just fine, but one equipped with a Touch-
Tone dialer will let you take advantage of long-distance
discount services such as Sprint or MCI.
Stepping Out
Once your computer is all dressed up with the right hard-
ware and software, you'll want to find someplace fun for it to
visit. You aren't limited to calling only other Color Compu-
ters. It makes no difference if the computer you call is an
Apple, an Orange, a TRS-80 or even a large mainframe
computer; in most instances, you'll be able to speak the same
language.
There are several ways of finding other computers to talk
to.
* Check The Source and CompuServe. Both publish lists
122
the RAINBOW
November 1983
of hundreds of bulletin board systems around the country.
The lists, however, are not always up-to-date because sys-
tems come and go faster than network television shows.
Notices of new boards are often posted in the Color Compu-
ter Special Interest Group section.
* Try a specialized newsletter such as PLUMB, which
contains news and features about all sorts of computer
communications systems plus a list of 100 bulletin boards
coded to show their features and special interests.
* Many CoCo boards contain a list of other boards that
are run on a CoCo or contain software and technical infor-
mation of interest to CoCo owners.
* Check the letters section in the Rainbow. CoCo owners
who start their own bulletin board system often send in
letters announcing their boards and listing their phone
numbers and hours of operation.
Your modem will know it has reached an available board
when it hears a high-pitched tone. Put your computer into
terminal mode and the two computers will shake hands and
determine if they are speaking the same language.
Most boards will introduce themselves, then ask if you
have a password. If you're a new caller, it will ask for your
name, the city you're calling from and perhaps your phone
number. Passwords are often required to use some of the
features, such as the download section. If you plan to be a
frequent caller, it's a good idea to ask for one.
Sysop Dru Simon makes callers pass an addition test if
they want to enter her "adult" sections. She asks a series of
questions designed to prove that callers are 21 years old. If
you can't answer her questions, you don't get in. And
software-seller Tom Mix says callers have to make five visits
to his board before they are allowed to begin downloading
software.
Once aboard, the system will show you a set of commands
for the functions it supports. One command may adjust the
screen width, another will move you from one section to
another, and so on.
Here's a sample of some of the commands found on many
Color Computer boards:
Application Lets you apply for a password
Configure Sets screen display parameters
E-Mail Lets you send messages to other board
users
Help Just what it says
Merchandise Catalog shopping section
Time Tells you how long you've been on the
board
View system Displays information about the board
Board numbers Displays a list of other boards
Download Lets you capture programs from the board
Goodbye Logs you off the system
Logs Shows a list of the board's regular callers
Sysop page Calls the board operator for an online chat
Upload Lets you contribute a program
Want ads Just like the newpaper
? Displays the command menu again
If you get confused, try the Help command or page the
sysop who can break in, talk directly with you and help you
find your way around.
Tech Talk
Many of the early systems were literally bulletin boards —
electronic versions of the push-pin-and-paper variety where

November 1983 the RAINBOW 123
notices of club meetings, equipment for sale and help
wanted ads were posted.
Ward Christiansen and Randy Suess, two Apple compu-
ter and ham radio hobbyists in Chicago, are credited with
writing the first BBS software for microcomputers. The
board was originally designed as an information clearing-
house for members of the Chicago Area Computer Hobby-
ist Exchange Club and their CBBS board (312-545-8086) is
still populated largely by want ads, meeting notices and
requests for technical advice.
Lee F. Blitch said he wrote a BBS program for his Color
Computer virtually out of self defense. "I had become a
telephone junkie. I was always calling other boards." His
board can be examined between 6:00 p.m. and 6:00 a.m.
(404-378-4410).
Blitch said he has sold about 15 copies of his BBS pro-
gram. Interest in telecommunications is relatively new
among Color Computer users, he said, "but I think you'll see
more and more of it."
Potential sysops, though, should be willing to put in some
hard work and a good bit of money. "The amount of work
needed to keep a board running is tremendous," said Mar-
shall Goldberg, founder of The Boston Bullet, a TRS-80
board. "The software has to be maintained perfectly and
your hardware is running 24 hours a day."
Blitch blamed the demands of the BBS for overheating
and his vintage 1980 CoCo.
"1 would warn anyone interested in running their own
board that if they don't have a lot of time on their hands,
they better not get into it," said Greg Moore, who runs a
Color Computer board in Arlington, Mass. (61 7-646-6809).
At least three BBS programs are available for the Color

Variety And Spice
Although most boards are stocked with technical advice,
some offer their own, unique features. Some may contain
stock market reports, movie reviews or online games. Dr.
D's board in Pensacola, for example, has a collection of
novelty peeks and pokes for the Color Computer and the
Doctor's own computer industry rumors and inside dope.
Some systems are also devoted to particular specialties:
* Education-80 in Greenwich, Conn. (203-629-4375)
keeps its eye on education conferences around the Northeast
and new developments in the use of computers in education.
* The Joke Byte board in Atlantic City (609-927-5922) is
loaded with some really awful jokes.
* The Apple-Med board in Iowa City (319-353-6528)
contains postings about medical conferences and reviews of
medical hardware and software.
* The Magnetic Fantasies board in Los Angeles (213-
388-5198) is devoted to discussions about science fiction
films, literature and software.
* Want to take a trip to the moon? Check out the Gas-Net
board in Greenbelt, Md. (301-344-9156). It's a board that
caters to people who want to keep up to date on space flight
programs.
* The Notebook in West Palm Beach (305-686-4862) is a
place for writers and editors to exchange messages about
freelance assignments.
What's Ahead
Several retailers of computer products have found that a
BBS is good for business. Moore and Dru Simon said
catalog sales of products listed on their boards help pay the
board expenses.
And Mix, owner of Tom Mix Software in Grand Rapids,
Mich., said his new board (616-364-8217) is a convenience
for both his business and its customers. They can call when
rates are lowest "and we don't have to answer the phone
after five o'clock."
Bob Rosen's business. Spectrum Projects of Wood haven,
N.Y., grew out of Connection-80. a board run on the Model
I that was the first board to exclusively serve the Color
Computer. Rosen has now added two other boards to his

Rosen and Mix are both working toward the time when a
large amount of software will be sold and delivered via
modem. A couple of other firms are already running such
systems. One is The Telephone Software Connection in
Torrence, Calif, (213-516-9432) which has developed a sys-
tem for high-speed transmissions to Apples.
Mix said he believes the day will come when vast amounts
of software will be purchased that way. Mix said he's work-
ing on ways to prevent rip-offs from such a system.
Others are using bulletin boards for other commercial
purposes, such as delivering customized stock reports or
special newsletters to members. Howard Young is a former
psychologist who explored using a bulletin board to post a
newsletter about software for investors.
Young said he thinks the frontiers of electronic informa-
tion exchange haven't yet been reached. "I think we're at the
infant stages of something that will be so explosive that
people will wonder why it took us so long to see it."

How To Be A Printer Artist
In One Easy Lesson
By Michael J. Himowitz
Ideas for programs can turn up in strange places. In this
case, it was the bottom of a cardboard box of 20-year-
old junk that 1 was rescuing from a flooded basement.
There 1 stumbled upon two books entitled Typewriter
Mystery Games that I had bought while I was taking a
typing course in junior high. They were very simple but, as 1
dimly remembered, a lot of fun. Each contained sets of
instructions for 15 different typewriter pictures: type so
many Xs, so many spaces, etc. The gimmick was that you
didn't know what you were creating until you were almost
through.
Immediately I thought of the computer and the advan-
tages it would have in using this kind of instruction. First,
when you're using a typewriter, you often don't know if
you've made a mistake until it's too late— then you have to
start over from scratch. And even when you have finished a
drawing, there's no way to reproduce it, short of using a
copier or retyping it. Creating your own drawings is even
more difficult for the same reasons.
The computer, on the other hand, gives you the potential
for retaining a drawing in memory and allowing you to edit
it. Eventually I developed several techniques for doing this,
the simplest of which is the program listed below. It is the
first step toward developing a library of printer artistry.
Also printed here are three different Printer Mysteries. 1
won't say much about them, other than they're appropriate
for the season. Look for more mysteries in future issues of
the Rainbow. These, by the way, were created by Julius
Nelson, author of many typing textbooks and the founding
father of the craft known as "Artyping."They are reprinted
with his encouragement and permission.
Here's how to use the program:
When you run Printer Art you will get a menu with six
choices:
1. CREATE A DRAWING
2. SAVE TO TAPE OR DISK
3. ENTER FROM TAPE OR DISK
4. PRINT DRAWING IN MEMORY
5. EDIT DRAWING
(Michael Himowitz is a Washington correspondent
for the Baltimore Evening Sun and proprietor of Fed-
eral Hill Software. He uses his computer extensively
and has written several programs including "CoCo
Accountant. " He is interested in meeting people who
use their computers in journalism.)
This is what the various options do:
1) CREATE A DRAWING— If you are using the pro-
gram for the first time, begin with this option. The computer
will ask if you want to print out each line you enter as you go
along. This is a good way to check on your progress, particu-
larly if you're creating your own drawings. But as you get
more familiar with the program, you'll probably want to
wait until the end and correct all your mistakes at once.
The computer will then ask you if you want to start a new
drawing or continue entering an existing drawing. If you
have a drawing in memory, starting a new one will erase
everything you have already entered. So, save one drawing
to tape or disk before beginning another one.
If you are starting a new drawing, the computer will
immediately prompt you for the first line. Select the mystery
drawing you wish to enter and look for the first line. We'll
use the first line of No. 1 as an example. The instructions are
as follows:
44SP 2%
Follow the instructions, type in 44 spaces ("SP" stands for
space) and 2 %s. Then hit the ENTER key. Do not put
additional spaces at the end of a line. When you hit ENTER,
the program will ask you if the line is correct. If it is correct,
type"Y"and the computer will prompt you for the next line.
If it is not correct, type "N"and the computer will ask you to
enter the entire line again. Line 2 consists of 43 spaces and 4
%s, and so on. Other lines include punctuation marks such
as colons and periods.
If you are doing your own printer drawings, do not enter
lines of more than 80 characters unless you have a printer
with a larger carriage and have instructed it to accept lines of
more than 80 columns.
The program has two features which will speed up your
work. If the line you are entering is identical to the previous
line, just type the word SAME and hit the ENTER key when
prompted for the line. If the line you are entering is identical
to another line earlier in the drawing, just type in the number
of the line you wish to duplicate. Forexample, ifyouareon
line 24 and it is the same as line 1 2, just enter the number 12.
You may create a drawing up to 80 lines long. When you
are finished with the drawing or want to return to the main
menu at any time, just hit the ENTER key with no other
input when prompted for a line.

in this article.
2) SAVE TO TAPE OR DISK— The computer will ask
you whether you arc using tape or disk (if you are using disk,
you still might want to make a tape backup to protect
against disk crashes). When you have answered, the compu-
ter will ask you for the name of the drawing. Enter a name of
no more than seven letters. If you are using disk, do not put
an extension on the name, as the program will automatically
add the extension "/ART" to your filename.

The program will prompt you to prepare the tape or disk
(insert a tape and depress the RECORD and PLAY buttons
if you are using a recorder). Then hit ENTER to save the
data. When the drawing has been saved, you will be returned
to the main menu.
3) ENTER FROM TAPE OR DISK-This is similar to
the SAVE function, the only difference being that you
should depress only the PLAY button of the recorder. If you
are using disk, do not put an extension on the filename. The
program will do this for you.
4) PRINT DRAWING IN MEMORY— This is the
payoff. The program will ask how many copies you want.
Enter the number, then position the paper so the printer
head is at the very top and hit the ENTER key. After a brief
delay, while the program figures out the centering parame-
ters, you will be told to hit ENTER again. The program will
then print out the picture, centered horizontally and verti-
cally.
5) EDIT DRAWING— When you have finished and
printed a drawing, you may notice errors or omissions. This
function will allow you to correct, delete or add lines to the
drawing.
To change a line, use option I . When prompted, enter the
number of the line you wish to change. The computer will
print that line on the screen and prompt you for a new one.
To delete the line, just type in DEL and hit the ENTER key.
To change it, type the whole line again (correctly this time)
and hit the ENTER key. At this point, the computer will ask
if you want to change another line. If you do, type "Y" and
the computer will repeat the process. If not, type "N"and
you will return to the main menu.
To insert a line, use option 2. The computer will ask you
where you want the line inserted. Enter the number of the
line immediately preceding the line you wish to insert. For
example, if you want to insert a line after line 23. ENTER
the number 23. Then type in the new line and hit the ENTER
key. Here the program will ask you if the new line you've
entered is correct. If it is not, the computer will go back to
the start of the process, which means you must again type in
the number of the line after which you want the new line
inserted.
Odds n Ends
The program will work with any printer. If you have a
printer with different fonts, you might want to experiment
by typing in directly the command for the font you want
before loading the program. It will not. however, work with
expanded 10 cpi fonts. Also, use of the condensed font
available with Epson. Gemini and Okidata printers will
result in a somewhat distorted picture because the type itself
is more elongated than the standard size.
Now YOU can create custom
overlays for your programs

I have also encountered a problem of some columns not
lining up because my printer is set to receive at 2400 Baud
(standard is 600 Baud). If you are running this fast and have
trouble, you might want to poke in a longer line printer
delay (POKE 151.128.POKE 152,0) to straighten things
out.
If you look carefully at the program, you may notice that
it converts leading spaces into "<" marks and colons into
"=" signs. This is because I/O routines have trouble with
these characters. The program converts them back to the
proper characters before printing.

four-program cassette and tutorial with 12 ready-to-run

ED
ED is both line and screen oriented This means that you can edit by line number or by
using screen type editing where you move the cursor to where you wish to edit and then
make your changes The line editing mode is very handy (or programming as most
assemblers and compilers refer to line numbers when an error occurs, thus making it easy
to correct if the editor like ED can go to a line number to edit Once there. ED can switch to
screen editing to make the corrections
EO also has cut and paste type ot editing, where you can split a line and move the other
halt You can also delete and rename files on disk from ED. edit more than one file without
leaving ED. and many more Here is a list of features

FHL ED/ASM has been recognized as the most versatile package in us price range for
FLEX Now the best is less Save $30 by buying ED ASM
LOOK AT THESE FEATURES
ASM
ASM is a fast and versatile (8 bit) macro assembler It has the necessary elements to
support strucfured constructs like WHILE and FOR etc These are the ability to detme
macros with substitutable parameters, conditional assembly directives, and the ability to
change the value of a label or symbol In addition, source code may be assembled in
modular form That is as a series ot LIBrary tiles A short file containing a list of tile
specifications in standard assembler source format may call as many library tiles as
desired Symbols detauli to a maximum length of 6. but may be redefined to a maximum
length ot 3 to 30 characters
ASM supports auto fielding and automatic label generation Labels may be automatically
generated and accessed within expressions.
This (unction has great power when used within macros An example is the BASIC
statement PRINT "HI" A macro would be created as
An example would be
BRA 1
FCC "Hl".4
EQU '
becomes:
BRA L0001
FCC "Hr',4
L0001 EQU '
ASM supports the following directives or pseudo operators.

This BASIC compiler generates pure, fast
efficient 8809 machine code from easy to
write BASIC source programs. 'Uses
ultra-fast Integer math, extended string
functions, boolean operators and run-time
operations. Output Is ROMmable and
RUNS WITHOUT ANY RUN-TIME
PACKAGE. Supports IF-THEN-ELSE
structure and random access. Supports
the following statements:
REM, END, CALL, FOR/NEXT,
GOSUB/RETURN, IF/THEN, ON ERROR
GOTO, ON-GOTO/ON-GOSUB, STOP,
GEN, STACK, INPUT, PRINT, CLOSE
FILES, OPEl\, CLOSE, WRITE, RWRITE,

SCRATCH, KILL.
Includes Chess In A/BASIC source.
Comment: A/BASIC does not compile RS
BbsIc or any other Basic. It Is an integer
only (no floating point), version of
BASIC. It can be used for games and
graphics, but it has no built in functions
for them. A/BASIC is a powerful addition
to your library, and it does not require a
license to use or sell the compiled code
produced from it. FH

Dynasoft Pascal is a portable p-code
implementation of a Pascal subset
specifically tailored for small scale
microcomputer systems.
Dynasoft Pascal is PASCAL SUBSET
which Includes the control structures of
standard Pascal and supports the data
types INTEGER, CHAR, BOOLEAN,
scalar (enumerated), subrange, pointer,
and ARRAY, along with the dynamic
memory management functions NEW,
MARK, and RELEASE. Its design is such
that It is virtually impossible to write
"spaghetti code", and the result Is
programs that are highly structured and
highly readable.
Dynasoft Pascal Is COMPLETE. I!
Includes a fast one-pass compiler, a p-
code Interpreter, a supervisor program,
and program SAVE, and LOAD routines
that can be adapted for media ranging
from paper tape to cassette to floppy
disks. For speed-sensitive applications
there Is a built-in interface to machine
language routines complete with
parameter passing.
Dynasoft Pascal is COMPACT. The
entire system will run on systems with as
little as 12K of available RAM without
overlaying. It produces ROMable p-code
which is also compactia typical algorithm
compiles to less than half the size of the
same algorithm expressed in the native
code of an 8-bit processor. This means
thnt you can get a lot of program In a
surprisingly small amount of memory.
Dynasoft Pascal Is PORTABLE. It Is
currently available for systems based on
the 6809 microprocessors and more are
planned. Programs written In Dynasoft
Pascal are compatible at both the source
and p-code levels: they can be
transferred to a new machine without
even re-complllng.

Dynasoft sets a new price/performance
standard with Dyna-C: a new Small-C
derivative unlike all the others. Pyna-C
produces compact, ROMable, position-
independent, re-entrant, OPTIMIZED code
that runs circles around anything in Its
price class. "C" for yourself:
As compared to Introl-C, Wordsworth 2.0,
Duggcrs, and Intersoft, Dyna-C has the
fastest Compile/load time, the fastest
execution time and the lowest price. (All
timings under FLEX9 at 1 MHz using
sieve benchmark from Sept 1981 Byte.)
Dyna-C supports a large subset of
standard C, including all statement types,
most operators (Including ?: and ,), and
all data types except float, long,
unsigned, struct, multidimensional arrays
and bitfields. It goes from your source to
executable binary in two quick steps: the
one-pass compiler with built-in pre-
processor AND OPTIMIZER produces
assembly code which is assembled straight
to binary using any standard 6809
assembler (including TSC's ASMB,
Microware's ASM, Lloyd I/O's OSM and
FHL's ASM). While this means maintaining
libraries In assembler source form it
actually saves disk space and time by
eliminating the loader step. It also
supports separate compilation so you can
split large programs or build your own
libraries from C.
Source code for the entire runtime
system is supplied, so you can customize
to your own needs. Requires 36K of user
RAM.

screen editor equally suited to the tasks
of program preparation and document
processing. With the addition of the
optional DynaForm print formetter/mall-
merge program it is a complete word
processing package for your OS9/FLEX
system.
DynaStar Version n features no-nonsense
"what you see is what you get" editing.
To edit, simply move the cursor where
you want it, and type. Any printable
character you type Is entered directly
into your text, and any non-printable
control character is interpreted as an
editing command and is executed
immediately. It's that simple! Single
keystroke commands move the cursor in
any direction, by character, word, tab,
line or screenful, and delete characters,
words, or a whole line. Two keystroke
commands augment the simple commands
by moving the cursor to the left or right
margins, top or bottom of the screen,
next paragraph, or the top or bottom of
the edit buffer. You can search for a
string, replace It with another, do It
again, mark text blocks, move, copy or
delete blocks, write them to side-files,
read them in somewhere else, set tabs
and margins, and center lines.
DynaStar features automatic word-wrap,
and optional right justification right on
the screen as you go, so you see how It
will look BEFORE you print It. For
programmers there Is an auto-indent mode
to help you write those well-structured
programs. DynaStar permits editing of

up, and the 0S9 version will even let
you go back to the Shell to do almost
anything you want (Including edit another
file) without even losing your place.
DynaStar Includes a unique macro facility
to let you define more powerful
commands by converting any control
character to a command/text string of
your choice. You can use this feature to
completely remap your keyboard if you
don't like the way we did It, and you
can provide a special "startup string"
which Is processed every time you enter
the editor to customize the editor to
your own taste.
For complete word processing, the
optional DynaForm text formatter
provides all the standard features
Including pagination, headers and footers,
single, double, and multiple spacing,
boldface, double-strike, and underline.
DynaForm has its own macro facility
with string variables, nested include files,
FULL MERGE/PRINT facilities, and
automatic generation of Index and Table

FLEX USERS:
Because DynaStar does its formatting on

a general word processor. DynaStar still
makes an excellent screen editor for your
programming needs and can be teamed up

value of 10. You can increase the value of a characteristic by
spending Power Points according to the following price
schedule.

Just like it says, press ZERO (0) to start over or press a
number from 1 to 8 to change the value of a characteristic. If
you press a number key from I to 8, the CoCo asks:
NEW VALUE?
Type your new value and press <ENTER>. The new value
appears on-screen along with a new TOTAL POINTS. You
can select a characteristic and enter a new value as many
times as you want until you get the character you want, with
exactly the number of TOTAL POINTS the GM said you
could have.
We begin by setting up fixed arrays to hold the character-
istic abbreviations (CHS) and the prices (PRICE).

This is a disk-based editor, macro assembler and
monitor, written lor Color Computer by Andy Phelps.
THIS IS IT — The ultimate programming tool!
The powerful 2-pass macro assembler features condi-
tional assembly, local labels, include tiles and cross
referenced symbol tables. MACRO-80C supports the
complete Motorola 6809 instruction set in standard
source format. There are no changes, constraints or
shortcuts in the source language definition. Incor-
porating all of the features of our Rompack-based
assembler (SDS80C), MACRO-80C contains many
more useful Instructions and pseudoops which aid
the programmer and add power and flexibility.
The screen-oriented text editor is designed for
efficient and easy editing of assembly language pro-
grams. The "Help Key" feature makes it simple and
fun to learn to use the editor. As the editor requires no
line numbers, you can use the arrow keys to position
the cursor anywhere in the file. MACRO-80C allows
global changes and moving/copying blocks of text.
You can edit lines of assembly source which are
longer than 32 characters.
DCBUG Is a machine language monitor which allows
examining and altering of memory, setting break
points, etc.
The editor, assembler and monitor — as well as
sample programs — come on one Radio Shack com-
patible disk. Extensive documentation included.

SOFTWARE DEVELOPMENT SYSTEM
The Micro Works Software Development System
(SDS80C) is a complete 6809 editor, assembler and
monitor package contained in one Color Computer
program pack! Vastly superior to RAM-based
assemblers/editors, the SDS80C is non-volatile,
meaning that If your application program bombs, It
can't destroy your editor/assembler. Plus It leaves
almost all of 16K or 32K RAM free for your program.
Since all three programs, editor, assembler and
monitor are co-resident, we eliminate tedious
program loading when going back and forth from edit-
ing to assembly and debugging!
The powerful screen-oriented Editor features finds,
changes, moves, copys and much more. All keys have
convenient auto repeat (typamatlc), and since no line
numbers are required, the full width of the screen
may be used to generate well commented code.
The Assembler features all of the following: complete
6809 instruction set; conditional assembly; local
labels; assembly to cassette tape or to memory;
listing to screen or printer and mnemonic error codes
instead of numbers.
The versatile monitor is tailored for debugging pro-
grams generated by the Assembler and Editor. It
features examine/change of memory or registers, cas-
sette load and save, breakpoints and more. SDS80C

Centronics-compatible parallel printer may be used
by adding the Micro Works' PI80C parallel Interlace.
For those of you with special terminal applications,
Microtext has selectable parity; it sends odd, even,
mark or space. With mark parity (which is default) you
can send to computers requiring either seven or eight
bits. All 128 ASCII codes can be sent. Exchange pro-
grams with other Color Computer users! Basic pro-
grams may be downloaded from other computers or
timesharing systems.
You'll find many uses for this versatile module!

sends the CoCo back to line 3 10 to start over. Lines 720 and
730 cause the CoCo to ignore any key other than a number

Things To Come
Next time we will start writing programs to store informa-
tion on cassette tapes. If you don't know how to set up and
use cassette files, we suggest you read pages 2 19 through 230
in "Getting Started With Color BASIC." Try your hand at
writing these programs:
•The Name Machine #1. Write a program to ask for a
name structure (See "GameMaster's Apprentice," July.
1983). then generate random names, one at a time. Press "S"
to save the name on cassette tape. Press the space bar for
another name. Press "N" to enter a new structure.
•The Name Machine #2. Write a program to ask for a
name structure, then generate names numbered zero through
nine. You can save any name to tape by pressing its number
key. Press the space bar for ten more names. Press "N" to
enter a new structure.
•The Name Machine A3. Write a program to select name
structures at random from a list of name structures (perhaps
in DA TA statements or in an array). Generate ten names
numbered zero through nine. You can save any name to tape
by pressing its number key. Press the space bar for ten more
names.
• Store Character Records On The Tape. Write a program
to store the name and seven basic characteristics for a char-
acter on a cassette tape. Enter the information from the
keyboard in response to questions on the screen.
•Find Character Record. Write a program to search a
cassette file for a character record by name of character. If
the record is found, display it. If it is not found, print an
appropriate message.
•Scan Character File. Write a program to read and dis-
play all records in a cassette file, one by one. Press the space

the RAINBOW November 1983
This, quite
literally, is the
color computer
America has been waiting for.
One of the best sellers in the
United Kingdom, the Dragon will
soon be manufactured by TANO
to serve American consumers
who want a serious, affordable
computer; one that has
proven itself at providing
educational and home
management applications as
well as fun and games. To
meet this challenge, the
Dragon was born. With a
standard 64K of RAM. A
professional typewriter-style
keyboard guaranteed for
20 million key operations.
And an impressive array
of options which include
disk controller and
drive, a printer, audio
cassette recorder, a
modem (RS-232 serial
I/O), joysticks, game
cartridges and a free
BASIC training manual.
THE COLOR
COMPUTER
YOU'VE BEEN
WAITING FOR.
Using the new 6809E Microprocessor (a great advance on
the original 6502 still used by our competition), the Dragon
brings advanced computer functions well within your
reach. And priced below $400, it's anything but expensive.
But these aren't the only points of difference with which
our Dragon roars. Unlike most units, the Dragon gives
Extended Microsoft"** Color BASIC as its standard
language while the competition is still stuck in Microsoft"**
BASIC training. The Dragon's advanced graphics features
include set, line, draw, circle, paint, print (a and print
using. Of course the Dragon also features advanced
sound capabilities.
"Microsoft" is a registered trademark of Microsoft Corp.
And full editing
features allow you
to insert, delete
or change at will.
Oh yes — don't forget
the colors! The Dragon features
nine; with five different resolutions
from 512 points of text (16x32)
to 49,152 points (256x192)
at high resolution. And you
can view these amazing
phenomena through
either your composite video
color monitor or VHF TV.
So goes the Dragon's
story. If you'd like to
know more, just mail the
coupon or call George
Merchant (our Director
of Marketing) toll free
at 1-800-327-7671.
Software developers
and dealer inquiries
are welcome. The
Dragon is destined
to become legend
as America dis-
covers its great
performance is
no myth.

FANTASY ROLE PLA Y1NG GAMES
Millions of young people, and many not-so-young,
are playing fantasy role playing games. A role playing
game is a game in which one or more players create
and control characters (adventurers) who live their
imaginary lives in a specially made game world. The
game world is created, managed, and operated by a
GameMaster (GM), also called a referee, adventure
master, or dungeon master (DM).
Most people who play role playing games use a
formal rule system. Some of the best known are shown
below.
Dungeons & Dragons (D&D). From TSR Hob-
bies, P.O. Box 756, Lake Geneva, Wl 53147.
RuneQuest (RQJ. From Chaosium, P.O. Box
6302, Albany, CA 94706.
Tunnels & Trolls (T&T). From Blade. Box 1467,
Scottsdale. AZ 85252.
Worlds of Wonder (WOW). From Chaosium,
P.O. Box 6302, Albany, CA 94706.
BEGINNERS BEWARE! The rule books are very
difficult to understand. If you are a beginner, first try
Worlds of Wonder or Tunnels & Trolls. Programs in
"GameMaster 's Apprentice" are based on the game
system used in Worlds of Wonder and RuneQuest.
For general information about fantasy role playing
games, try the following book, excellent for beginners.

WHO KNOWS WHAT'S for the
CoCo? Already, Radio Shack has given
us one of the most sophisticated operat-
ing systems on the market in OS-9. and
now, this month an Ink Jet printer will
really liven things up for the Color
Computer.
But, truth he it known, there are more
and more people — including those in
Fort Worth, as we hear it —working on
loads and loads of other things for
CoCo in the months and years ahead.
A year ago we wrote that a full-blown
compiler would be one of the best things
to come down the pike, when and if one
did. There are a couple on the market
now, and so we must wonder where
things will go from this point on.
One of them seems to be in the area of
memory. And, in this instance, "memory"
would seem to come in two forms:
dynamic memory and disk storage.
Yes, we know that disk storage does
not fall into the area of memory per se,
but it is a viable way to increase the
storage capacity of a computer.
We are reminded of an article which
Alan J. Morgan wrote in an early issue
of the Rainbow which spoke about the
need for additional memory. Morgan's
thesis at the time was that programmers
who are able do not need more memory
— though they might need more storage.
If you will think about that for a while
and add in the fact that most things for
which you need memory can be done
with a disk as well — sorts, for example
— then the line does begin to blur
between "real" memory and storage
"memory."
Couple that to the fact that even
though dynamic R A M memory is becoming
less and less expensive, "real" memory is
still a pretty costly proposition. And
that includes bubble memory as well.
Truth to say, although there have
been some interesting, from a technical
point of view, articles in several journals
concerning bubble memory, the fact is
that it probably won't be viable on a
cost basis for CoCo. Just too expensive
to produce on a mass basis.
That leaves our hybrid, disk memory.
And. after you hook up four disk drives,
what can you do?
Why, do to a hard disk, of course.
We expect that there will be some
moves toward a hard disk for CoCo in
the coming year. Whether they arise
from Tandy Center or elsewhere, it
seems certain that this is the way that
things will go in the future. And we'll be
surprised if someone doesn't have a
hard disk drive for CoCo available by
this time next year.
And what else? Rumors. seem very
persistant about even newerColorComputers
from Radio Shack. We could be wrong,
but we don't see anything really innova-
tive in the next few months. One of the
things Tandy seems to have done is to
generate two "lines" of CoCos, with the
64K and the CoCo 2. We think they'll let
the dust settle for a little while before
things start popping again.
One other trend we see. though, is for
more "home" education products to
make their appearance. We're not talk-
ing about formal educational setting
materials, though there will be more
and more of those, too. We believe the
computer at home is a very viable
appliance, if you will, and the develop-
ment of quality "home education" pro-
grams is a very real market, along with
the other, more traditional, ones.
HIGH RESOLUTION screens seem
to be all the rage right now. The Rain-
bow has already reviewed at least one of
these packages. Super Screen by Mark
Data Products. Another one, for use
with OS-9 from Frank Hogg Labs, is
due for review in a future issue.
Now comes still another, called Hi-
Res Screen Pak from Cer-Comp. The
Cer-Comp version allows for all kinds
of different displays, including double-
wide and double-high characters. It
allows use of PRINT@ and will display
up to 255 characters per line. The high-
est character-per-line displays are not
readable, but they do allow you to for-
mat page layouts and the like.
SPEAKING OF GRAPHICS the new
idea of the month award goes to All
Event Video for its Comp-U-Trace pro-
duct. This is a screen overlay that lets
you place a clear, reusable vinyl overlay
that you can attach to your screen and
then "trace" the same picture with pro-
gramming. Very interesting.
While on the subject of graphics,
there is a new product out from The
Micro Works called Magigraph for the
experienced BASIC and ML programmer.
This new program will allow drawing of
very detailed graphics, including use of
a full set of logical operations and pixel

ANOTHER AREA WHERE we are
seeing some rapid growth in the compu-
ter world is in the spreading of program-
sales stores. Two of the most active
firms in this area have been The Pro-
gram Store and Software City.
What is most interesting to us in this
area is that the primary aim of such
chains is software, not hardware. In
many ways, this breaks the mold of the
"traditional" computer store — which
pushed one or two brands of computers
and, for that reason, carried little more
than software for the brands they carried.
Judging from the success of The Pro-
gram Store and Software City (The
Program Store has just opened a fran-
chise in Littleton, Colo, and Software
City is moving into London, England),
we believe this is a development that will
prove interesting in the months to come.
BRIEFLY NOTED . . .
The Software Connection in Fort
Lauderdale has something everyone near
a large body of water might be inter-
ested in owning: A hurricane tracking
program.
Mark Data Products, which pioneered
CoCo Adventure games, is out with new
one: Shenanigans, which is said to com-
bine both text and graphics and which
does not require a disk system.

REDCHASE
By Rich Dersheimer
This program changes the text screen to the orange/ red
mode, clears the screen to red blocks, and then demonstrates
a chaser for the lo-res color graphics.
The color changes can be used to highlight titles and
instructions, or if used in groups of eight, for a burst of
colors without changing the original block graphics.

Now, You Can Easily Generate
Graphic Data
Statements
By Fred B. Scerbo
One of the greatest strengths of the CoCo is the ease
with which one can create graphic displays and
drawings without having to POKE complex geo-
metric formulas to the screen. Commands such as CIRCLE,
LINE. PAINT, DRA W, GET. and PUT can be used to
manipulate any sections of the graphic screen so as to dis-
play any item which you have the patience to draw. Add to
this the release of the X-Pad by Radio Shack and a variety of
drawing programs by independent software dealers, and
you can create almost any kind of graphic display in up to
four true colors at one time.
What happens if you use one of these graphic generators
to create a detailed display which you wish to incorporate
into a BASIC program? Most will allow you to save the
contents of the graphic memory to tape ( CSA VEM "name"
1 536,7679,0) or to disk (SA F£A/"name ",3584,9727.0). This
can be later loaded back into memory from a program.
However, there arc several drawbacks to this technique.
First, tape and disk versions can not be interchanged
unless they are offset loaded, which can be tricky.
Secondly, you cannot shrink your graphics down to a
smaller size.
Thirdly, using the machine language screen dump re-
quires additional I/O from tape or disk.
Fourth, there could be no opportunity for a listing of your
graphic display in a magazine such as the Rainbow , unless it
were a dump of the graphic memory done with POKE
statements.
Here is where we introduce the Graphic Screen Data
Compiler. This short program will take whatever graphics
you have drawn on the graphic screen and create a BASIC
program which will recreate the same graphic from DA TA
statements using the DRA Wcommmand.
Before we go any further we should probably explain
exactly how the CoCo's graphics work. When you draw in
any PMODE, your graphics will remain in the graphics
memory until you use the PCLS command. You can even
(Fred Scerbo is a Special Needs instructor for the
North Adams Public Schools. He holds a Master's in
education and has published some of the first software
available for the Color Computer through his software
firm. Illustrated Memory Banks.)
wipe your program memory clean with the NEW command.
Your graphic memory remains untouched.
(You don't believe me? Try this. Write a few lines to create
any graphic display with the commands you are familiar
with, such as:
10 PMODE4,l:PCLS:SCREENl,l
20C1RCLE(128,96),20,1
30 GOTO30
RUN the program and then enter NEW and LIST. Now
type SCREEN], l:FOR 1=1 TO 2000:NEXT and press
[ENTER]. Your graphics are still there.)
Therefore, if we draw a graphic display by whatever
means we choose (a program, the X-Pad, a graphics pack-
age, etc.), we can load in the Compiler without destroying
our graphics. We can save only part of the screen if we wish,
since the program asks us at which position on the graphic
screen we wish to start and end, from vertical position
through 192.
While the Compiler will work in 1 6K, it is likely to create a
ready to run program which will only run in 32K. (Sorry
about that for you I6K folks. Now would be a good time to
upgrade.)
Here is how the program works. Each graphic line from
to 192 is analyzed pixel by pixel. The Compiler then writes
two DRA ^statements counting the number of pixels and
their color. Two statements are created per line since a single
statement might exceed 255 characters, the maximum
length of a STRING. When the line has been compiled, the
program will write the statement to either tape or disk
preceded by a line number and the command DA TA. The
information is written in ASCII form so that when we try to
reload the file the Compiler creates, we will be loading a
ready to run BASIC program. (The CoCo's internal mecha-
nisms recognize this as a BASIC program when it sees the line
number.)

When you run the Compiler, you may choose either tape
or disk. Simply follow the instructions shown on the screen.
Now let us talk about the drawbacks to this program. The
Compiler is very slow. After all, it is analyzing a tremendous
amount of information and compacting each string as it is
created. (The program may take up to half an hour to create
the ASCII file so if you are using tape, make sure it is at least
a C-60.) Once you have created your file program/ BASIC
program, you may reload and run it. It is wise to resave the
listing since the ASCII version loads more slowly than a
normal CSA VE.
Notice also that the Compiler uses the PMODE4 and
PMODE3. If you wish to change to another P MODE you
must alter the listing yourself.
You will notice that I have included REM statements that
say speed up and slow down. If you wish, you can use the
high speed POKEs, especially with disk (while some will).
Simply insert POKE65495.0 to speed up and POKE65494.0
to slow down. If you use one, however, you must use the
other, otherwise you will crash your disk or mess up your
tape. If you are really daring, use POKE65497.0 to speed up
and POKE65496.0 to slow down. This will disconnect your
screen and fill it with garbage while the data is being ana-
lyzed so do not press break or you will lose the program.
You will gain some speed with these POKEs but you are
probably better off being patient. Walk away from your
CoCo and let it do the work for you. After all, that is why
you bought a computer. Just imagine how long it would take
to write these DRA If statements by hand!
Earlier 1 mentioned using this program to shrink your
graphics. Here's how.

Keep the rest of the lines the same. What you have done is
draw only halfway across the screen since you have changed
size from 4 to 2 in the DRA ^statement. By switching from
PMODE1 to PMODE4, you will have created a graphic half
the size of the original. You can rerun this graphic through
the Compiler and create the lines needed to recreate this
smaller graphic inside another BASIC program. Experiment.
What uses can this be put to? You can generate small parts
of the graphic screen which can be merged with other BASIC
programs. Create a complex small graphic which you can
read into a G£7"and PUT statement in your own games.
With a little manipulation, you can generate DRA W state-
ments small enough to fit into a 16K game. The process is
slow, but once it is done, the results can be pleasing and you
can use a graphics package to create detailed, arcade-like
graphics for your own BASIC programs.
In time, 1 hope some of you will use this Compiler to
submit some complex graphic computer art for Lonnie to
run on his Radio Shack Color Graphic Paint printer for
inclusion in the Rainbow. This could even become a
monthly competition or listing. Then all of you can really
show off your CoCo's power to those friends of yours who
bought a fruity computer. (Just dare them to try it on their
machine.)
Included with this article is a printout from the Rainbow's
CGP-220 Ink-Jet Printer created from a very long but
detailed graphic listing which displays everyone's favorite
alien in PMODE4. (Rememberthisisjustanartisticdisplay
and cannot be used for promotional purposes as the actual
image is protected from such unauthorized use for profit.
Still, cartoonists use this image for artistic expression, so
that is what we are doing here. This is for your own use
only.)
The listing for DRA W-EZ is not reproduced in the maga-
zine, due to its extreme length, but is included on Novem-
ber's Rainbow On Tape. DRA W-EZ requires 32K since
there is so much detail in the drawing. Those of you with
I6K might try part of the listing just to see the results partly
displayed.
Now let's see what all of you can come up with. Let's see
some real computer art submitted to the Rainbow for future
issues. You have the tools to do it now. ^^^,

r ^\
Welcome back to the land of fantasy gaming. You
may recall that we have been putting various
portions of the tedious work associated with
record-keeping and character creation process on the com-
puter. The built-in problem with this has been simply that
the existing fantasy role-playing games were never designed
or written with computers in mind.
Having realized that, we have been working on a combat
system designed from the ground up to be computer sup-
ported. That has been very well received, so what you see
here is the start of a grander (perhaps grandiose) plan for a
whole fantasy gaming system designed from the ground up
to be computer supported.
This summary of the new game is not cast in concrete, and
some of what is below will possibly be altered in the future,
but we have been test playing it for about two months in our
own group, so you will find most of it to be workable as is.
There are eight character attributes, and each of these are
found by rolling five four-sided dice, throwing out the low-
est two, and adding up the highest three. In the listing below
you will find a neat little program to roll up characters and
also check to see which characters qualify to be which races
and classes.
You will notice that when a character is rolled up, you
have a choice to reroll or continue. If you choose to con-
tinue, you will find the program ends with an error. That's
because 1 haven't written the rest of the program yet. Even-
tually the program will do a very complete character genera-
tion. Well then, on to the summary.

THE MAGIC SYSTEM-A Quick Overview
The colors of magic are complex, and we will go into them
in detail next time. To quickly summarize, players must
align themselves with the white, green or black if they are an
Arcanist, Guardian, or Champion. The main thing to keep
in mind here is that these colors are not related to the
concept of alignment used in many games. A character's
choice of magic color is unrelated to good or evil. There are
several other colors of magic known, but they may not be
used by player characters.
There are three levels of magic. These are trivial or trick
spells, battle spells, and regular spells. There are also several
levels of power among regular spells. A spell user can cast
spells each day up to the limit of his force points. These are
figured as follows: Faith + Intelligence + Stamina + (Level *
3). Trivial spells use one point. Battle magic uses two points,
and regular spells use their power level times five points. If
the caster is a warrior, rogue, or thief, then double force
points are used up in casting spells.
Magic is written in a special language that can be learned
by anyone having an intelligence of nine or more. Once the
language is learned, any character may try to cast spells as
detailed below. If you cast spells past the limit of your force
points, the extra is deducted from your hit points, and these
will be recovered at the rate of one per week. There has never
been a case recorded of them being recovered more quickly.
Arcanists and Guardians can form a chain of power. This
will combine their force points and chance of success.
DESCRIPTIONS OF CHARACTER CLASSES
Warrior: To be a warrior, a character must have agility of
seven, stamina of nine, and strength of nine. A warrior has a
combat adjustment of six. If a warrior learns the magic
language, he can try to cast spells of trivial and battle magic.
Thief: To qualify as a thief, the character must have an
intelligence of eight, speed of eight, agility of nine, and
manipulation often. The combat adjustment is three.
Thieves have the following abilities: PICK LOCKS 30% +
(5% * (level -1)) + (5% if manipulation is 1 1 or 15% if 12).
PICK POCKETS 30% + (5% * (level -1)) + (5% if manipula-
tion is 1 1 or 15 % if manipulation is 12). STALKING 40% +
(5% * (level - 1 )) + (5% if intelligence is 1 or more) + (5% per
point above 10 of agility). HIDING 30% + (5% * (level -1))
168
the RAINBOW November 1983
+ (5% if intelligence is 1 or more) + (5% per point of agility-
above 10).
When a characteristic reaches 85%, it begins going up 2%
per level, and can never exceed 95%. If you fail to pick a
pocket, the intended victim always notices the attempt.
Also, picking pockets is just that. It confers no ability for
more complex maneuvers. It is impossible to stalk or hide in
noisy or shiny armor. If a thief learns the magic language, he
can try to cast spells of trivial and battle magic.
Rogue: To be a rogue requires physical beauty of ten,
intelligence often, speed of eight, agility of nine, manipula-
tion of ten, stamina of nine, and strength of nine. This
character has the combat adjustment of a fighter and the
thieving skills of a thief. Rogues can cast trivial and battle
magic spells, as well as regular spells up to first power level.
Check out the points for rising in levels before choosing this
class. No complaints later!!!
Arcanist: If you have intelligence often, manipulation of
nine, stamina of eight, and faith of nine, you can be an
arcanist. Combat adjustment is zero. Arcanists must choose
between the green, black, and white, and can never turn
back from a chosen way. The chance of successfully casting
a spell (assuming directions are at hand) is: Intelligence * 5 +
manipulation * 3 + Faith + (level -I)* 10. This is for a spell
of first level of power. The chance goes down by 25% for
each level higher. However, there is always a 3% chance of
failure or success. Each time you correctly cast a spell, your
chance on that spell goes up 2%. If you miss a spell by 25% or
more, you must roll on the dreaded spell mis-fire table to see
what happened.
Guardian: You need an intelligence of nine and a faith of
12 to be a guardian. A guardian must choose between the
green, black, and white, and can never turn back from the
chosen way. Combat bonus is two. A Guardian can turn
aside undead if he successfully rolls a saving throw. How-
ever, the level of the undead is added to his roll. The chance
of successfully casting a spell (assuming directions are at
hand) is: Intelligence * 3 + Faith * 5 + (level -1) * 10. This is
for a spell of first level of power. The chance goes down by
25% for each level higher. However, there is always a 3%
chance of failure or success. Each time you correctly cast a
spell, your chance on that spell goes up 2%. If you miss a
spell by 25% or more, you must roll on the dreaded spell
mis-fire table to see what happened.
Champion: These fighters for the cause need an intelli-
gence of ten. faith of 1 1 . speed of ten, agility of ten, stamina
of ten, and strength of ten. No. we won't see many of these!
These fighters have a combat adjustment of 6, and because
of the force being with them, they are + 1 to hit. They can cast
regular spells of the arcanist up to first power level, and
guardian spells up to second level. However, only spells of
the proper color can be cast. Champions are immune to
poison of any kind. If they leave the way of their color, they
will invariably sicken and die of unknown causes.
For All Classes: Hit points are Faith, Stamina, and
Strength added together. When hit point level reaches zero,
the character is unconscious. Death occurs at double the hit
point level below zero. Each level after the first adds one hit
point. Females subtract two from strength and add two to
manipulation. They get the benefit both ways. If the deduc-
tion drops them below needed strength, they qualify any-
way, and if the manipulation brings them up to qualifying
level, that's fine too.
Climbing: All classes climb the same. For a rope or easy to
climb wall, the formula is (Agility + Strength + Level) * 3.

standard deviation, correlation coefficients, covariance. F and t tests. Powerful data editing and manipulation abilities such as trans-
formation of variables including log. exponentiation, raise to a power and multiply by or add a constant. Data plotting, Student t tail
areas, Gaussian cumulative probability distributions, and more. Flexible I/O (screen or printer, tape or disk). Very good documentation.
16K Extended BASIC Cassette S29.95
SIMPLEX — New!! Linear programming by the "simplex" method now available for the Color Computer. This powerful decision making
tool finds the optimum "mix" for a given set of constraints. Ideal for business students, teachers, and professionals. Dynamic model dimen-
sioning, with maximum size approximately 45 constraints and 45 variables. Disk compatible. 16 page manual included 16K Extended
BASIC Cassette S29.95
PAGE PLUS — Attention BASIC programmers! Here is the software you've been waiting for! Up to 56K available from your BASIC
programs. This utility, written by Chris Hawks, does the memory management necessary to utilize the two 32K banks of memory. Easy
enough for any "intermediate" level BASIC programmer to use. Includes documentation and demo programs to Show you how to use
PAGE PLUS to get the most out of your computer. Works with 64K tape or disk systems. Cassette S27.95 Disk S29.95
MDISK — Hal Snyder's latest breakthrough for the 64K Color Computer! MDISK lets you use the upper 32K of memory for rapid storage
and retrieval of programs and data. Whether you own an actual disk drive or not. MDISK puts the "hidden" 32K to work for you as a "virtual
disk," with capability to save and load up to 15 programs, view a directory of files stored in "page 1 ," kill unwanted page 1 files, execute
BASIC or machine language directly from MDISK, chain to a BASIC program while preserving data already created, and more. These
functions are available not only under manual keyboard control, but from programs in progress as well, permitting high-speed swapping
of programs or data. Unlike many 64K utilities, MDISK doesn't copy BASIC to RAM. This greatly increases the amount of workspace
available to you (by 22K in a disk system). MDISK is written in position independent code, and will work on disk or tape based 64K systems.
Full documentation included. Cassette S27.95 Disk $29.95
ROMBACK — Why pay more? The easiest to use ROM-pak dumping utility available! At the best price, too! Comes with full documentation,
including detailed patching instructions to allow several popular "problem" cartridges to run from tape or disk. Stop plugging and
unplugging your disk controller! Don't blow any more SAM chips or 6809Es! Use ROMBACK. and run those programs from tape or disk
instead. Works with any 64K Extended BASIC system. Cassette $16.95
QUICKSORT — A machine language sort routine specifically designed to be used by BASIC programmers. Speeds up those programs
where a BASIC sort is just too slow. Great for mailing lists and databases. Can be incorporated into many existing programs as well.
Written in position independent code, works on tape or disk systems. 16K required Cassette S12.95
64K BOOT/PAGER — The 64K Boot allows you to modify BASIC by moving it from ROM to RAM. The PAGER is a menu-driven utility
allowing you to manually page between the 32K banks of memory, copying BASIC or data from one page to the other. The complete
assembler source code for both programs is included. Both are written in position independent code and run on 64K tape or disk systems.
Cassette S19.95
STRUCTURED MACROS — An assembly language programming tool for users of the Macro-80C assembler, by the Micro Works.
Structured macros come close to transforming your assembler into a high-level language. Your programs become more understandable
and debugging is simplified. Commands include IF, ELS, ENDIF, IFTST, IFCC, WHILE, ENDWH, REPEAT, and UNTIL. Disk $19.95
WIZARD 64 — If you've got 64K, then this one's for you! Uses both 32K pages of memory for graphics and action— combines the features
of Wizard's Tomb and Wizard's Tomb Part II into one great game. Challenging enough for adults, yet entertaining for younger players too.

For easier or harder conditions, the adjustment will be
provided by the moderator. Use percentile dice.
Finding Secret Doors: : All races have the same percen-
tage of chance. If not actively looking, the chance is (Intelli-
gence + Level) * 2. If looking, the chance doubles.
Fin and Remove Traps: Everyone has the same chance.
(Intelligence + Manipulation + Level) * 2. Roll twice —
once to find and again to remove. The moderator rolls the
chance to find. Use percentile dice.
Races: There are three races which can be player charac-
ters. These are Human, Elf, and Dwarf. Anyone can be
human — there are no qualifying scores.
Elf: These need physical beauty ol 1 1 . intelligence of ten,
agility of ten, and manipulation of ten. They subtract one
from the initial rolls of the dice for strength and stamina,
and the result must be less than nine or it will be reduced to
make this so. These adjustments are made after class qualify-
ing, and the hit points are reduced when applicable. Elves
have wood sense, which operates only above ground. They
are never lost, they can find any available food or water, and
they sense large ( man-size or bigger) animals within 1 50 feet.
It is not possible to sneak up on an awake elf above ground.
Dwarf: If you covet Dwarfhood. you need a strength of
eight. Dwarves subtract one from speed and physical
beauty, and if either of these ends up higher than eight, it will
be reduced to that level. Again, this is done after class
qualifying. Dwarves have stone sense when below ground.
They can sense pits in the floor large enough to fall into, and
hollows in the rock larger than ten feet across within 50 feet
— even if blocked by rock. They never bump into walls
underground, even in pitch blackness. They can't see them,
but they know they are there. They are never lost under-
ground, and always know the distance to the surface.
In the case of both elves and dwarves, the "never lost"
assumes that they went to a place while aware. If they are
teleported or carried unconsious. they won't know where
they are.
Saving Throws: If a saving throw is required, the charac-
ter must roll a 30-sided die and obtain a number lower than
their current force point level divided by two and rounded
down. A 30 always misses and a one always succeeds. The
moderator will specify plusses or minuses as necessary.
That's about it for this month. Below is the character
generating program. Remember, it works as is, but isn't
finished yet. We will be adding on to it next month. In the
meantime. 1 want to warn you to beware of the dragons in
this game. They are very, very powerful. No more easy
Dragon treasure! By the way, the tentative name for the new
game is Dragon Magic, suggested by Pal Zircher, the artist
who drew the pictures at the head of this column every
month. If vou have a better name, let me know.

DATA COMMUNICATIONS
An Introduction To
Synchronous Data Transmission
By Harry Hardy
In the April and June issues we took a look at asynchro-
nous transmission, in particular as to its relationship
to the Color Computer. As we now know, asynchronous
transmission can be implemented rather inexpensively and
is rather efficient, at least for our needs. We also know that
the error detection methods are not foolproof and error
recovery is seldom implemented. Finally, asynchronous
transmission is usually limited to speeds less than 2400 bits
per second (BPS). Probably 300 and 1200 BPS are more
commonly used. I have heard that faster speeds can be used,
but I'm not familiar with those devices. Speeds up to 9600
BPS are used but the only asynchronous terminals IVe seen
operating at speeds this high are connected directly to a
computer for in-house use only or they have some kind of
protocol converter to convert from asynchronous to syn-
chronous transmission. We'll look at that later. Well, that's
enough about asynchronous terminals for now, let's look at
some newer technology.
Since the theme this month is communications I thought 1
would introduce you to another type of data transmission
where speeds up to 56000 BPS (56K BPS) are not uncom-
mon, and even speeds up to 1 .54 million BPS and faster may
be found. This type of transmission is called synchronous
transmission.
Before we look at this technology, 1 should let you know
that my background is with large IBM mainframes using
either their terminals or what are known as plug-compatible
terminals, mainly those made by Teletype Corporation.
Since this environment (IBM) is my forte, the examples we
will be looking at will be of those device types in particular,
however the principles involved apply to all devices capable
of synchronous transmission, also some of the examples will
apply to asynchronous transmission; where this overlap
occurs 1 will point them out.
A good place to start is to look at how synchronous
transmission differs from asynchronous. You may recall
that 1 defined asynchronous transmission as one that lacked
any continuity between transmitting and receiving stations,
and in order to achieve this continuity or synchronization
start and slop bits were used so the receiving station could
get synchronized on the character being transmitted so it
would know when to start assembling bits into a character.
Let's briefly look at how efficiency is affected in an asynch-
ronous environment.
(Harry Hardy, who has 15 years experience as an
applications and systems programmer in telecommun-
ications is currently employed as a telecommunica-
tions consultant by a large company that provides data
communications products and services.)
Assume we are using an 8-bit character which will be
preceded by a start bit and end with a stop bit. That gives us
a total of 10 bits per character. Since each and every charac-
ter will require these framing bits, we have a 20 percent
overhead on each character being transmitted. As you have
probably figured out, if you are transmitting a lot of data,
this 20 percent overhead can really delay the actual process-
ing of this data by your program. For example, if your
program requires 100 characters of information to process a
given transaction, 200 of the 1 ,000 bits, or 25 characters, are
overhead to your program to get the 100 characters you
require.
How does synchronous transmission differ from this, you
ask? Well, to help understand this let's look at the RS-232C
interface you have heard about. This interface is a standard
that has been agreed upon by the Electronics Industries
Association (E1A) for interfacing different manufacturers'
terminal and computer equipment. The RS-232C port on
your Color Computer meets this standard, even though in
just about the most simple form possible to perform data
communications.

If you look at the cable you connect
to your computer and your modem, you
can see the obvious differences in plugs.
The computer end is round and has only
four pins, while the other end is flat and
rectangular in shape. Although there
may be only four pins in that end, there
is space for 25 of these pins. Figure 1
lists these pin assignments by number
and E1A circuit identification. Note
that all pins are not assigned; however,
some modem manufacturers do make
use of these unassigned pins. We will
not discuss those pin functions here
since assignment purposes may differ by
modem manufacturer.
Your Color Computer uses pins 2, 3,
7 and 8, a very simple EI A interface for
data communications. Synchronous and
some asynchronous transmission devi-
ces use several of the other pins. Let's
see which ones as we proceed.
Synchronous transmission, in addi-
tion to the transmit data lead (pin 2),
requires either a separate clock lead
from the transmitting station, or a mo-
dem that includes the clocking informa-
tion when it encodes the data, converts
from digital to analog. In other words it
is up to either the DTE or the modem to
provide the timing, or clock, as it may
be referred to, that was accomplished by
using start/ stop bits in asynchronous
communications. At the transmitting
end this clock signal, if provided by the
computer, is received on pin 24 from the
computer. This signal is then put on pin
2 at a different frequency level than the
data. If the modem is providing the
clocking, then the clock signal is re-
ceived from circuit DB (figure 1 ) or pin
15 on the modem, not the computer.
This clock signal is then placed on pin 2
just as before. At the receive end, this
signal, data and clock, are found on pin
3. Let's not get into the electronics of
how this is done, but what happens is
that, at the receive end, this timing, or
clocking, is recovered from the side-
bands of the received signal to indicate
to the DTE the appropriate instant to
sample the data stream on the received
data lead, pin 3, for a character or
information. This recovered clock sig-
nal is then placed on pin 17 for the
receiving station. This inclusion of the
clock "beside" the data stream provides
the synchronous continuity that is lack-
ing in asynchronous communications.
By providing this continuity we have
defined the term "synchronous trans-
mission." By the way, in probably 99
percent of all installations the modem
provides this clocking, not the DTE.
By eliminating the start/ stop bits, we
have created a couple of side effects.

One is good. While the other may seem bad, it is easily
overcome. First the good; since all bits are used to represent
data, we have eliminated the 20 percent overhead or the 20
percent waste characteristic of asynchronous communica-
tions. Now the other side effect. As you recall 1 said that
those start/ stop bits served another purpose besides timing,
that being framing bits. This meant that the presence of a
start bit indicated to the receiving station to assemble the
next eight bits into a character, the following stop bit indi-
cated to start monitoring for the next start bit. Since these
framing bits are absent in synchronous communications we
must provide another method of determining which group
of bits constitutes a character. Sound like a problem? Not
really— in fact, the solution is quite simple. Let's see how this
is accomplished.
The framing of each character is accomplished by defin-
ing a synchronization character, commonly called a "syn"
character. This syn character is usually one that has a bit
pattern different from that of any of the regular characters
that are to be transmitted in a data stream. This is done for
reasons that will become obvious. We wouldn't want the
DTE to think that the bit pattern for the letter A is a syn
character. This would create a lot of problems, as you can
see. Each reception of the letter A would indicate to the
receiver to start assembling bits that follow as a character
and to ignore the letter A. If your DTE transmits in ASCII,
the syn character is made up of the bits 01 101000. In the
world of IBM, this character would be 001 10010. Why the
difference? IBM equipment uses a code called EBCDIC,
extended binary coded, decimal interchange code. This code
uses all eight bits for data, therefore 255 possible characters
can be represented where only 127 characters are available
with ASCII. Although their synchronous devices talk
EBCDIC, their computers can support certain synchronous
devices using ASCII.
Back to our syn character: No matter which one we use it
will precede the data characters in all transmissions. It seems
we've reduced our overhead quite a bit by sending a syn
character before each block of data. Well, there's a little
more to it. Suppose the first syn character loses a bit along
the way. We then lose our data, for the DTE wouldn't know
it was to collect the following bits as data. Well, to allow for
this condition we send one more syn character than is
required. Typically one syn character is required, therefore
our synchronous device will send two syn characters. I
know, you don't have to remind me— what if both syn
characters are destroyed? Well, the line has to be drawn
somewhere. We could send 25 syn characters, but then we
would be approaching our 20 percent overhead again, so
what's the point? Just like in asynchronous transmission,
why not send 20 stop bits in case the first 19 are destroyed.
Ridiculous, huh?
So. we will send two syn characters followed by our data,
correct? Well, let's look a little deeper and sec what we can
find (sounds like we may be losing ground on our savings).
Actually each synchronous transmission has four characters
of overhead. Besides the two syn characters, we have a
leading and a trailing PAD character. The leading pad bits
are 01010101 and the trailing pad bits are all ones, to the
computer. From the computer, all transmissions must have
at least two syn characters, data, and a trailing PAD charac-
ter. This PAD has the format of 1 1 1 1 xxxx where x is either a
I or 0. So from the computer we have three characters of
overhead. In addition to this, two syn characters are auto-
matically sent every second during transmission to or from
the computer. This is done to make sure the model clocks are
still in sync and the data is being sampled at the correct
interval.
Does it sound like we haven't gained any in the overhead
department? Let's look at a situation and see if that is really
the case. Consider the speeds at which we transmit in a
synchronous environment. For a computer to terminal data
link, the speeds are usually 2,400, 4,800 and 9,600 BPS—
7.200 BPS may also be found. Probably 4,800 BPS is the
most common speed with 9,600 rapidly gaining in popu-
larity.
Let's say we are running at 4.800 BPS and we have 594
characters of data to transmit. We also have four overhead
characters, those being two PADS and two syn characters,
and possibly two syn characters will be sent in the middle of
our data. Add all those up and you can see we have 600
characters with eight bits each for a total of 4,800 bits to
transmit. Of these 4,800 only 48 are overhead. That works
out nicely, for depending on the distance between sending
and receiving devices, we can send this data in one second.
Now. take those same 594 8-bit characters and send them
asynchronously. We would still have 4,752 bits like before,
however we now have an additional two bits per character,
or 1 , 1 88 bits overhead for a total of 5.940 bits. Besides this
excess overhead we see that we can't even send the data in
one second, assuming we could transmit asynchronously at
4,800 BPS. For you mathematicians, that's one percent
versus 20 percent of overhead. Let's not get too anxious; in
short blocks of data we would still have those 32 bits of
overhead. In those instances— I didn't figure one out— the
overhead in synchronous transmission would outweigh the
asynchronous overhead; however, in a busy interactive sys-
tem that isn't likely to happen very often during the actual
transfer of data between computer and terminal.

Now that we have some idea of how synchronous trans-
mission works, what about the line discipline or protocol
that is used to govern this type of transmission? There are
different types of synchronous protocols, but I will focus on
only one of them here. The reason is that, although the
Color Computer doesn't support synchronous communica-
tions, other personal computers do. Apple. Radio Shack's
Models 12 and 16, and IBM's PC offer a package that
supports binary synchronous protocol. Maybe you own one
of those computers in addition to the Color Computer or
maybe you have been thinking about getting one. In either
case, let's look at some of the concepts of this protocol.
Binary synchronous, or bisync as it is more commonly
called, has an extensive set of control codes to ensure that
the transfer of data is done in a very accurate and precise
manner. In addition to a choice of error detection schemes,
it also employs a complete error recovery procedure. There
are three types of bisync configurations, these being: point-
to-point private line, point-to-point switched line, and a
private line multipoint configuration.
The choice of error detection methods is dependent on the
type of terminal. If the terminal uses ASCII to represent
data, then VRC and LRC are used, resulting in a one-byte
block check character. If the terminal uses EBCDIC then
the CRC-16 method of error detection is used resulting in a
two-byte block check character (BCC). CRC or Cyclic
Redundancy Check is an error detection method in which
the check character is generated by taking the remainder
after dividing all the serialized data bits of a block by a
predetermined number. With CRC-16. the 16 tells us how
many bits are in the BCC. providing error detection of
bursts up to 16 bits in length, with more than 99 percent of
error bursts greater than 16 bits being detected. Therefore.

systems that use the CRC method of error detection are
more effective at detecting errors than those that use
VRC/ LRC.
As I said, there are several control codes used by bisync to
control data flow. Let's define a few of them.
SOH — Start of heading.
STX — Start of text.
ETX - End of text, terminates a block of data
and indicates BCC character(s) is next.
EOT — End of transmission, indicates the end
of a message, is also used to respond "nothing to
transmit" to polling sequence. More on that
later.
NAK — Negative acknowledgement indicates
previous block received with an error, retransmit
data.
ACKO/ ACK I — Positive acknowledgement in-
dicates previous transmission was received error
free. ACKO is used to acknowledge even-num-
bered blocks. ACK I is used for odd-numbered
blocks.
WACK — Wait before transmit positive acknow-
ledgement indicates that previous block is error
free, but receiver is not ready to receive next
block.
RV1 - Reverse interrupt, a positive acknow-
ledgement, but is is also a request for the trans-
mitting station to terminate the current trans-
mission as there is a high priority message
waiting to be sent.
ENQ -■ Inquiry, used to bid for the line in a
point-to-point environment. In multipoint, it
indicates end of polling or selection sequence.
Also used to request retransmission of NAK or
ACK if the response was garbled or not received
when expected.
DLE - Data Link Escape. One use is in for-
matting WACK. ACK, or RV1 as these are two-
character codes. Example: ACKO is DLE1 or
1031 in ASCII. Another use is to indicate trans-
parent text mode. This mode is necessary to
transmit binary files such as machine language
programs, for some of the characters in this type
of file can be bisync control codes. DLE STX
start transparent mode. DLE ETX ends it.
There are a few other codes, but these will be enough for
our example. For the first example, let's look at a point-to-
point data link (figure 2). This type of data link is also

YOUR COLOR COMPUTER JUST GOT WHEELS!
REVOLUTION!
You accelerate hard down a long straightaway,
braking heavily at the end for a hard 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 final 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 are
playing Revolution!
FANTASTIC ACTION
Revolution uses high resolution, machine language graphics
for action that is smooth and fast. The emphasis is on
authenticity in the control and motion of your car. As in
driving a real race car, accuracy and precision in your driving
are what counts. Frills and non-essentials have been left out.
PURE COMPETITION
Like a real race driver in practice and qualifying sessions, you
compete against the clock and against the existing lap record
for that track. Revolution records the lap records and the
name of the person who set the record, so you always know
who reigns supreme on your favorite track!
DESIGNED WITH YOU IN MIND
Revolution is menu-driven, and self explanatory. Informa-
tion screens tell you what you need to know. When you're
ready to play, a menu of the names of all your tracks is
displayed, along with the lap record for each track and the
name of the person who set that lap record. You select a track
with a single keystroke, and Revolution takes you there.
A NEW CONCEPT
Revolution is a unique game, because it allows you to create
the most important part of any race game: the track itself.
The first time you run Revolution, you will be able to choose
from several tracks and cars which are included with the
game.
But, with Revolution, this is only the beginning! You can
create as many tracks as you like. You can make each new
track as difficult or as easy as you wish. You can make easy
ones to begin with, and tougher ones as you become more
skilled. You may find creating tracks to be almost as much
fun as driving on them!
You can save your favorite tracks to run on again whenever
you wish. Revolution will automatically add these new tracks
to the menu. And you can exchange your favorite tracks with
other Revolution owners.
Be careful, though, about letting your friends play this game.
They may not want to let you have your computer back!
THE EARLY REVOLUTION
A prototype version of Revolution was published in the
September, 1982 issue of Rainbow magazine, under the
name The Track. The response to The Track has been terrific.
Revolution has all the features that have made The Track a
favorite, and Revolution's fast, high-resolution machine
language graphics are dramatically improved over the
prototype's.
REVOLUTION NOW!
The original Revolution for the TRS-80™ Color Computer
requires 32K and one disk drive. A new cassette version has
action just like the disk version, and similar track-saving
features excluding a menu of available tracks. The cassette
version will run on a32KColor Computer or TDP-100. You
can upgrade to the disk version later, too, for a nominal fee.

known as a "contention" system. I'll explain that in a
moment. Before I do, let's get an idea of what the format of a
message would be. 1 haved used the / to separate fields and
the data flow will be from left to right.
/BCC/ETX/TEXT DATA/ STX/ HEADER DATA/ SOH/
The header may or may not be present, but all other fields
must be.
For our point-to-point example we will be transmitting
between points A and B in figure 2. Let's start by sending a
message from the computer "A" to the device at point "B."
This could be some type of terminal or another computer.
Location A will start by sending an ENQ asking "are you
ready," B will respond with an ACKO. "A" will then send the
message followed by ETX and appropriate BCC. If B
received the message error free, it will respond with an
ACK1, A can now send another message or send EOT
saying "I have no more messages to send now."
If the message was received with an error being detected B
would send a NAK and A would then have to re-send the
message. This time, if it was error free, B would respond with
an ACK I . If another error was detected the NAK sequence
would continue a predetermined number of times, then A
would send an EOT, and probably notify an operator via the
system console that an unrecoverable error has occurred
and would not try to send the message again until some
command from the operator instructed it to do so. Once this
command is entered the scenario would start over with an
ENQ.
Now, suppose that after all messages were sent by location
A and an EOT had been sent, A had another message to
send. At this same instance, suppose B had a message to send

to A and they both send an ENQ to each other. Interesting
situation, if I do say so myself, for neither will respond with
an ACKO since ENQ is an invalid response to an ENQ. We
now have defined why this type of link is sometimes called a
contention system, for both have "bid" for the line and
neither can get control. This situation only happens when
both bid for the line at the same time. If point A had not bid
for the line, B would have control and could send its mes-
sages in the same fashion described above for point A.
To get around this problem a concept termed "Master/
Slave" is used. What this means is that the location desig-
nated as the control or master station will bid for the line in
an interval that is less than the slave station, in this example
point B. This enables point A to seize the line and send its
messages prior to point B. Thus, we have eliminated this
"contention" problem.
These are the basic concepts of a point-to-point data link
using bisync regardless of the type of facility used, switched
or private line. What about this new configuration called
multipoint? The rules governing this type of configuration
are different; let's see how.
Unlike point-to-point bisync, the remote terminals in a
multipoint environment can never initiate the transfer of
data, they can only send data upon an invitation to do so.
Look at figure 2 again. I have included a multipoint circuit
which contains four points. Point A again will be used to
represent the computer, while points D, E and F could be
anywhere from as nearby as the same building, or as far
away as across country. Each remote point has an intelligent
controller with two terminals each. We could have as many
as 32 devices per controller, and as many as 32 controllers
per circuit, however I doubt there would ever be a single
circuit with that many devices ( l ,024) as I suspect response
time for each transaction could, depending on the applica-
tion, be unacceptable.
Each controller has all the intelligence to perform error
recovery as described earlier, and has enough RAM for
buffer space to handle all the devices attached to that con-
troller. Now that we know something about each of these
controllers, let's see how we will communicate with them.
In a point-to-point environment we saw that if one station
wanted to send data to the other, it bid for the line by
sending an ENQ. We can't do that with a multipoint circuit
for we wouldn't know which device bid for the line, and
when the computers bid for the line, each controller
wouldn't know if we wanted to send data to it or one of the
other controllers. How do we get around this? Well, the
computer would solicit data from each location by invita-
tion or "polling"as it is called . There are two types of polling
we could do. One is called a "general poll," the other is a
"specific poll." A general poll will ask a particular controller
for data from any of its terminals, whereas a specific poll will
ask a particular controller for data from a specific terminal.
Let's see how that would work.
Suppose we wanted to see if controller "F" had any data
from either of its two terminals. The computer would send
the general polling characters for that location. Those char-
acters for location "F" would be FF""ENQ, or 4646222205
in ASCII. Bisync always sends the station's address twice. I
don't know why that is, just the way it was designed. That's
why two Fs are sent. The two ""s indicate that it is a general
poll and the ENQ simply asks "Do you have anything to
send?" If it does, controller "F" would respond by sending
the data with the appropriate framing characters such as
STX, ETX and BCC. If the data was received error free, the
computer would respond with an ACK-0; if an error was

detected it would respond with a NAK and the same error
procedure would be followed as described for a point-to-
point data link. If controller F had no data from either
terminal, it would respond to the poll by sending an EOT.
Why didn't controllers "D"and "E" respond to the poll?
Well, even though each of these controllers did see the poll
on the line, they knew by the two Fs that the poll was not
meant for them and simply ignored it. Had we wanted to
poll either D or E, the Fs would have been replaced with the
characters of the controller we wanted to communicate
with.
Now that we have just received a message from controller
F, we probably want to send some kind of reply for the
operator. Maybe the message received was a request for the
work location of an employee and we needed to get that
information back to the terminal. To do this we would do
what is called a "selection" sequence for that particular
terminal on controller F. But how do we know which con-
troller and which terminal on that controller to select? Well,
part of the data we received from the poll were the codes that
identify the controller and terminal that requested the infor-
mation. The software in the computer would be aware of
this and would save this information for the reply. Now that
we know which terminal to select, how do we do it?
Assume we need to send the reply back to terminal A on
controller F. The selection codes for controller F now must
be different from those used for a poll so the controller will
know what we are trying to do. The selection code for
controller F is 57 in ASCII. That is the code for the letter W.
The code for terminal A will be 41 in ASCII. Our selection
sequence will then look like this: WWAAENQ, or 5757414105.

it would respond with an ACK-0 and the computer would
now send the data. If it was received error free the controller
would respond with an ACK-I. Again, if an error was
detected by the controller, the same error procedure would
be followed.
When do we use a specific poll? Well, this could be done
instead of using a general poll, but it would take longer to
service each terminal on a controller. Example: suppose
controller D had I0 terminals. We would have to do a
specific poll for the first nine before we got any data from the
10th one. That's not too efficient, particularly if the first nine
had no data to send. Probably the most common use of a
specific poll would be in the case where the host software
determined that part of the data it received was incorrect, an
invalid part number, etc., and sent a message to the terminal
notifying the operator of this error. We would do a specific
poll to receive this corrected information so we could pro-
cess the transaction. Again, the specific polling characters
would be unique to that device. For controller F, terminal
A, the codes would be FFAAENQ or46464l4!05 in ASCII.
As you can see, this is similar to a general poll except we
have replaced the two quotation marks with the terminal
code.
One more example, then we will leave this topic. Suppose
that device B on controller D has some kind of problem
— perhaps this device is a printer and it has run out of paper.
Also, assume we have just selected this printer for output.
Obviously, we can't print without paper, so in response to
the selection the controller will respond with an RVI. This
RVI is a positive acknowledgement but it is also saying, "I
have a problem with one of my devices, if you will poll me I
will tell you what it is." The host software would then poll
the controller and receive this status message. All status
messages take priority over any other messages. In response
to this status message the host would send an EOT or RVI.
Now we can poll the terminal for input, but we still can't
send any data to that printer until the error condition is
cleared. How would we know when this happened? In
response to some future poll, the controller would again
send us a new status message saying "the problem has been
cleared, you can now select that device."
As you can see, multipoint is a little more complicated
than point-to-point; however, there are benefits that make
this extra effort worth it. The major ones are probably line
cost, and the saving of ports on the computer. In our exam-
ple, we had six terminals on one circuit. If it wasn't for this
multipoint capability, we would have to have six separate
lines that would probably be more expensive than one mul-
tipoint line, plus we would need five additional ports to serve
the other locations.
Now that we've seen how bisync protocol works once each
point on the data link is ready to communicate, let's take a
quick look at what happens prior to any data transfer taking
place. To do this, I will be referring to Figure I again. The
first two pins we want to look at now are pins 4 and 5,
request to send and clear to send. Before the DTE will send
any data it will first turn pin 4 ON to condition the modem
for data transmission, and on a half duplex circuit to control
the direction of data transmission. If the modem is ready it
will turn pin 5, clear to send, ON. The DTE can now send its
data. There is some delay in this RTS/CTS sequence. The
actual amount of delay is dependent on the modem being
used, but typically this delay will range from 50 to 250
milliseconds.
There are two more leads we should consider: those are
pins 6 and 20, data set ready and data terminal ready.

Data set ready is used to indicate that the local terminal
equipment is connected to a communications channel; it is
not in any type of test mode; and, for switched lines, any
timing functions required by the switching system to com-
plete a call have been completed.
Data terminal ready is used to control switching of the
data communications equipment to the communications
channel. The ON condition prepares the equipment to be
connected to the communication channel while the OFF
condition causes the equipment to be removed from the
communication channel following the completion of any "in
process" transmission.
This should take care of the pins, or at least most of them,
that are required to perform data communications. This
interface is a standard and all types of data transmission
may make use of the pins discussed, or at least part of them.
As you know, we only need four of them for use with the
Color Computer. For a complete definition of all the El A
leads there is a publication available from the Electronic
Industries Association in Washington, D.C. The complete
title of the document is Interface Between Data Terminal
Equipment and Data Communications Equipment Employ-
ing Serial Binary Data Interchange. "
So far. we have been discussing the use of modems, thus
implying that our facilities, whether private line or dial-up
are analog. We know that these analog facilities were origi-
nally designed to transmit voice and in order to transmit
data we must convert the sending DTE's digital signal to
analog and back to digital for the receiving DTE. This
conversion process does take up some time no matter how
minute this time period may be. Why not have facilities that
are all digital and eliminate this conversion period? Well.
such facilities are available. Let's take a brief look at some of
them.
So far, we have been talking of speeds up to 9,600 BPS
using modems and the various telephone companies'analog
facilities. There is an offering by AT&T called Dalaphone
".. .with fiber optics already
being capable of transmit-
ting at speeds over 400 mil-
lion bits per second, who
knows what tomorrow will
bring?"
Digital Service, or DDS, that supports speeds of 2,400,
4,800 and 9,600 BPS without any additional equipment,
except a device called a Data Service Unit that replaces your
modems. This is an all-digital offering and is designed for
synchronous transmission only on private lines. The inter-
face at the DSU is the same standard RS-232-C interface as
we found on modems. This service allows you to still use
telephone company facilities and it is maintained by them.
There are other digital services available; however, they
all require special equipment to be installed at the user's
locations. These offerings include microwave, satellite,
AT&T's High Capacity Transport Service (HCTS), and Bell
Labs' Fiber Optics. HCTS offers two speeds, 1.344 and

1.544 million bits per second. The other three offer speeds
from 2.400 up to several million BPS. Also, DDS has a
56,000 BPS offering. Since we know there aren't many, if
any, terminals that operate at speeds above 9,600 BPS. how
can we make use of these speeds beyond that?
Let's take a look at Figure 3 and see how we can do this.
What we have here is several ports from the computer going
into something called a multiplexer. The multiplexer will
take the data from each of these ports, combine the data into
a single data stream and transmit all the data at a high rate of
speed to another multiplexer which will separate the data
and send it out on its ports onto the appropriate lines to the
attached devices. The same is done for data coming from the
remote network to the computer. In this example. I show a
56K BPS DDS data link between multiplexers. This data
link could be any one of the other services as well. For
9600 bp.

example, this link could be two earth stations transmitting
to each other via a satellite.
By the way, if your computer network was all asynchro-
nous you could make use of these high speed data links, for
some multiplexers have the ability to convert the async data
stream to synchronous and even perform error checking and
recovery for you.
What is the advantage of using these types of services?
First of all, we can see that these systems were designed for
the large users. By using such a system they could be saving
in line cost. for. instead of having several circuits they would
only have the one high speed link. The time period to realize
a savings will, of course, vary depending on the type of
service providing the data link. Satellite earth stations and
the service itself aren't cheap. Of course, there may be situa-
tions where you wouldn't have much choice as to which
service to use. For example, if you had a data center in Los
Angeles and one in Australia, you might have to use satellite
services to get there.
As you can imagine, there are other configurations that
we could use these high speed facilities for— let's not get into
all of them here in any detail — but some more uses would be
to transmit voice, facsimile, and of course, television
broadcasting.
1 hope it has been interesting to look at some ways to
transmit data and to look at some of the new technology that
is available today. And, with fiber optics already being
capable of transmitting at speeds over 400 million bits per
second, who knows what tomorrow will bring? I'm not
saying you will ever have an earth station in your backyard,
or a microwave tower on your roof, but just think: with the
way technology is progressing and the cost of hardware
continuously comingdown. maybe one day when you log on
to your favorite bulletin board with your home computer it
may just be at 4.800 BPS or higher. Wouldn't that be nice?

TUTORIAL
BASIC is a special type of computer language in that it is
interpreted. This means that a machine language
BASIC interpreter program must be resident in the
computer to run a BASIC program. While a BASIC program
runs, the interpreter takes each statement in turn, looks up
what to do, and goes to the code in the basic interpreter that
performs the required task. If you run a FOR TO NEXT
loop that prints "X" 100 times, the interpreter must look up
the PRINT token 100 times. This takes time. In a machine
language program, either the address of the required code or
the distance, in bytes, to the required code is in the program
and the microprocessor goes directly to the address. How-
ever, getting or writing a program in machine language takes
some doing. Most high level languages produce a machine
code file. Some run directly. Others need some runtime code
that interprets an intermediate code. Best is a stand alone
machine code file that you can LOAD, EX EC and be in the
program.
OF THE
80s
C was written in 1972 by Dennis Ritchie at Bell Labora-
tories. Ritchie worked closely with Ken Thompson in devel-
oping the UNIX system. Nearly every software tool now
supplied with UNIX including the operating system is writ-
ten in C. Subsequently, C has just grown in use on its own
merit. It has not had true believers out preaching the faith
and bad mouthing competiting languages. It has not been
"marketed." More like a carpenter choosing a good saw to
quicker finish the job, programmers have chosen C so they
can get good code to their client faster and get the paycheck.
C feeds the family, if you will.
LANGUAGE
Writing in assembly language is one way to get to a
machine language program. The assembly language source
code is run through an assembler program which converts
the assembly language to machine code also called the object
code. Assemblers can be remarkably small, efficient pro-
grams. Radio Shack's EDTASM+ for the CoCo combines
an editor, assembler and a monitor to run the machine
program under operator control in less than 8K bytes.
Another approach is to write in a language whose source
code is converted to machine language by a program called a
compiler. Fortran, PL/ 1, and Pascal are all compiled lan-
guages though Pascal needs a runtime program to interpret
the compiled file. Cis unique in that it compiles to assembly
language source code for the microprocessor in question
and the assembly language file is then assembled to obtain
the final machine code file. C is a small language so its
compiler is small. A limited, but very useful C compiler fits
easily into 16K. There now exist a number of C compilers for
CoCo as well as a number of excellent references the begin-
ning programmer needs to learn the language. Further, C
has been implemented on many other micro and mini com-
puters in such a way that C text is more transportable than
most other languages. For these reasons, C makes a good
loice for a next language to learn after BASIC.

C comes out of a family of languages whose traditions
stress reliability, simplicity and ease of use. An international
committee designed ALGOL 60 in 1960. Highly sophis-
ticated, ALGOL has had major influence on programming
language design but never caught on in the United States.
Combined Programming Language appeared in 1963 as an
attempt to "retain contact . . . with the realities of an actual
computer." But, CPL was big and its hosts of features made
it hard to implement and hard to learn. Basic Combined
Programming Language was a 1967 attempt to boil CPL
down to its basic good features. Ken Thompson at Bell Labs
further simplified CPL to B to use on an early implementa-
tion of UNIX. But, BCPL and B were so condensed that
they could only deal with certain kinds of problems. Build-
ing on these roots, Ritchie's C restores some lost generality
without sacrificing simplicity or "computer contact." As for
power, C's limited stock of parts can be assembled into more
complex parts and combined into elaborate assemblies.
How does one get to the machine program using C on
CoCo? Here are the mechanics without going into language
details yet. First, an editor or word processing program is
required that supports all the characters available from
CoCo's keyboard when running in BASIC. Unfortunately, I
thought that my beloved Telewriter-64 did not make the
grade since characters like the backslash did not seem to be
available and are indispensible to C. I subsequently made
the mistake of reading the instructions (nobody ever does
that) and found the backslash is CLE AR-COM M A and was
provided just so Telewrher-64 could write Ctext. Two other
needed characters were found by typing errors. These are "["

produced by SHlFT-@ and "]" produced by SHIFT-
CLEAR. In the mean time, a surprisingly good editor, Mr
Ed, was published in the June 1983 Rainbow, page 140. I
modified the program to accept lowercase commands (Bits
and Bytes of Basic, Rainbow, August 1983), modified the
program name line to follow C's comment convention and
have been very satisfied.
The Csource code for the program is prepared, edited and
saved to disk. Oh yes, C runs on disk only and gives a disk
drive quite a workout. Cassettes just cannot do what has to
be done. The C compiler is then loaded and executed. The
compiler calls the C source code and converts it to assembly
language source code which is considerably larger than the
Ctext. During the process the CCompiler is reading in the C
source from one disk file, converting it and saving assembly
source to another disk file. Little of either C or assembler
code is in memory at any time and you can combine a
number of C source files to make a large assembly source
file. Next, the assembler program is loaded from disk and
executed. It goes to work on the assembly source file and
you sit back while the disk chugs and chugs some more. I do
believe the disk gets warm after a five to 10 minute session of
constant rotation. The output object code is on disk now
ready to LOA DM and EXEC. If all went well you have a
"C comes out of a family

tions stress reliability,
simplicity and ease of
use."
running machine language program. Since all never, ever
goes well with any computer program in any language, the
program will probably bomb and you will enter the debug-
ging phase. Actually, the Ccompiler sends a variety of nasty
messages which you will have responded to prior to assem-
bling a corrected assembly source file so the problems now
are ones of basic program logic and not ones of language
systax. Now you can start to see one of the negatives of a
compiled language compared to BASIC. When you write in
BASIC, you need only RUN the program to see if the code
you just entered works. With a compiled language, you have
to compile your source code , and in the case of C, assemble
it before you execute it.
C is a structured language. You need to declare your
variables by type before you use them in each function that
they are used. Further, variables are local to each function
except those declared before "main()". This is somewhat like
using DIM in BASIC in that it reserves space for that varia-
ble. Then you write your code in groupings called functions.
These are analogous to subroutines in BASIC, but are named
and are called by name. There are also standard functions,
some of which are provided with the Ccompiler, which are
not part of the language, but which you call from your
program to perform certain tasks. C itself has no input or
output statements. These are all in the standard library,
provided with the compiler, and are written for the specific
computer in question.

So. what does C source code look like? Following is a
simple program that prints a table of Fahrenheit and Celsius
temperatures. The table is not exact since the program per-
forms integer math only.
/* FAHR CELS.DAT */
/ * print Fahrenheit-Celsius table for fahr=0, 20 300 */
main()
@
char c;
int lower, upper, step, fahr, Celsius;
lower = 0; / "Mower limit of table*/
upper = 300; /*upper limit*/
step = 20; /* step size*/
fahr = lower;
while (fahr <= upper) @
Celsius = (((5* IOO)/9)*(fahr-32))/ 100;
printf("%d %d/n", fahr, Celsius);
fahr = fahr + step;
S
c=getchar();
$
#asm
LIBS 1NCLIB.TXT
#endasm
First note that C is written in lowercase. The first two lines
are comments enclosed by the / *. . .*/ delimiters called for
by the compiler. Then main() defines the start of the pro-
gram which is enclosed between the first @ and the last $.
Next the variables are all declared, in this case as a character
(char) and as integers (int). Variables can and should be
meaningful words since this makes the source easier to read.
Don't worry about space. None of the comments or varia-
bles get to the object code from the assembler. The "while
(fahr<= upper)" is a control structure that tests if fahr is less
than or equal to upper. As long as this is true, the following
three lines between the @ and the S are executed. The first of
these lines calculates the value of Celsius from the current
fahr value. Then, both values are printed using printf().
Printf() is one of the standard library functions that is
tailored to the particular computer. It is somewhat like
PRINT USING in BASIC as it provides for some print
formatting. The "%d%d/ n" tells printf() to print a number.
%d, print a few spaces, print a second number, %d again and
then start a newline, /n. The variables containing the two
numbers follow as fahr and celcius. In the library are a
number of utility functions like printf(). Typically, the
library file may be in a C compiler readable format and
added to your program by the compiler or it may be in
assembly language and added by the assembler. You can
develop your own set of functions and keep them in a library
to be added to your own programs or to be shared with
other. Finally fahr is incremented by step (20) and looping
continues until the test after "while" becomes false. Then
this program goes to the next statement after the S which is
"c=getchar()". getcharQ is another library function that
works just like C=INKEYS in BASIC. Here it serves to stop
the program until a keyboard entry is made so one can read
the table.
All function calls, even main() which is a function, are
followed by parentheses where data to be sent the function is
listed. In the printf() example, the peren's contents was

("%d%d/n", fahr. Celsius). The printf() code got the full
string of characters within the quotes and copies of the
values in fahr and Celsius. How printf() handles its work to
get the values of fahr and celsius onto the screen is of no
concern to the programmer. printf() is a black box that
prints things to the screen in a way the programmer can
control through what goes into the perens.
A C program is really a set of user written and library
functions. Execution starts in main() where needed func-
tions are called in their order of need. Ideally, main() will be
as simple as possible with major blocks of logic in other
functions which in turn call functions including themselves.
This system makes C usable for a variety of programming
tasks where needed statements are not in the kernel of the
language. C has no math functions like log, sine, cosine,
powers and the like. But, utility functions to do the tasks can
be written and used just as the printf() function was used.
Likewise Cdoes not contain any string handling statements
like RIGHTS, LEFTS and M1DS. Again, functions to do
these things would need to be written or obtained from
others who have already written them.
If, after all this, you are still interested in learning more,
start with The C Primer, by Les Hancock and Morris
Krieger, published by McGraw-Hill Book Company
(S 14.95). This and the other books mentioned below can be
obtained generally off the shelf. Some computer stores will
carry one or more of these. If the Primer turns you on. you
will certainly need a copy of the bible. This is The C Pro-

that the beginner finds the water quite muddy. But such
conciseness is on the mark in a reference volume for the
serious user. In addition this book is the definition of Stand-
ard C which is closely followed by most users and writers.
Finally comes "The C Puzzle Book," by Alan R. Feuer,
Prentice-Hall Software Series ($14.95). This book provides
a series of short examples program for you to figure out with
detailed analyses at the back.
"A C program is really a set
of user written and library
functions."
But, it's no fun just reading and figuring while the compu-
ter sits cold on the table. Dugger's Growing Systems has an
ad for their C compilers in this issue. I have the one for
TRS-DOS which fits into a I6K machine. More memory
may be needed for the text editor and text file, but not for
either the compiler or the assembler. At this writing. Version
1 .2 supports only the most necessary parts of the language.
Version 2.0 implements another chunk and should be avail-
able by the time this is published. Duggers Compiler for
FLEX is the 2.0 Version. Also coming from Dugger is a text
editor written in C and an assembler written with assembly
and linkage of C produced source code in mind. The Version
1 .2 TRS DOS compiler was designed using Computerware's
assembler. One of the attractions of this assembler is the
ability to include LIBS assembler commands which will call
additional assembly source files and combine these to pro-
duce a single object file. The other available Ccompiler for
CoCo is from Frank Hogg Labs and also runs under FLEX.
1 have no information on this program. However, if it is an
adaption of a compiler for another 6800 or 6809 based
computer to the CoCo (one of the things FLEX makes
possible) it may be the most comprehensive compiler for
CoCo. Perhaps users will report their experiences.
By now you should know enough about C to decide to
look further or not and know where to look should you
choose. Obviously, we can only hope to touch a few bases in
an article like this. To summarize and to help you calibrate
your expectations should you go further, here are a few
thoughts. If assembly language programming is low level
and BASIC, PL/I, Pascal and others are high level, C is
somewhere in the middle. A lot of thebellsand whistles of a
high level language are not there. While the BASIC pro-
grammer has access to the machine with PEEK, POKEand
VA RPTR, these are used with restraint, in C there is need to
deal with addreses of data and manipulating pointers to
data. As I read about Cand its syntax logic. 1 think about
how the computer is working more than I do when pro-
gramming in BASIC. Finally, assembly language pro-
grammers should find Ca natural step up the ladder since C
permits assembly source inclusion within the Ctext. in the
example above, #asm and tfendasm enclose an assember
command. They could just as well enclose assembly source
code that the compiler passes directly to the assembler as
part of the assembly source stream. ,=-

DATA COMMUNICATIONS
Communicating With
Your Color Computer
By Bob Rosen
One of the added features of the Color Computer is
the built-in RS-232 interface. It can be used to hook
up a serial printer like the DMP-100. More impor-
tant, though, it can be used to help you communicate.
Communicate? That's right! There is a whole new world of
telecommunications that many CoCo owners are unaware
of. Besides playing games and writing programs, you can
connect a modem to your RS-232 port. A modem is an
electronic device which converts the computer's electrical
pulses bit by bit into audible sounds that can be transmitted
over the telephone lines. Modem stands for MOdulator/
DEModulator and there are two types available.
The two main types of modems currently on the market
are the direct-connect modem and the acoustic-coupled
modem. Both have their advantages. The direct-connect
unit hooks right into the phone lines. For instance, Spec-
trum's Mini-Modem allows you to unplug your phone from
the jack and hook it into our unit. Then you can plug the
cable from the Mini-Modem back into your phone jack.
This assumes that your phone and jack are modular. If not.
Radio Shack sells two adapters, 279-393 and 279-351, that
will convert your hook-up to modular. Since the direct-
connect unit hooks right into the line, virtually no external
noise can be detected which means someone else in the room
can be watching TV or listening to a stereo. The acoustic-
coupled modem is even easier to hook up. The attachment is
the same as adding a telephone answering machine. If you
have no extra jacks. Radio Shack sells two "Y" adapters,
279-357 and 279-370. for modular and four-prong systems.
The acoustic-coupled modem is more susceptible to line
noise as you are placing your phone's receiver into the unit's
two cups, or "synthetic ears." This can be a problem if you
are calling long distance and the signal on the other end is
weak. Another problem is that today's modern phones
might not fit the modem's circular cups (Slim line phones,
for example). One advantage to this modem is that it is more
flexible to use with multi-line phone systems than a direct-
connect because all you have to do is push buttons to use the
modem on another line.
(Bob Rosen is president of Spectrum Projects and has
been running a successful CoCo mail-order business
for a year and a half. He is ably assisted by Paul Rosen,
Tom Delabo, Tom Genoski. Jerry Lato, A I Hartman.
and Mel Silverman.)
The only other piece of hardware you will need for your
modem is a serial cable to hook it up to the RS-232 port. For
the Mini-Modem, you will need a 4-pin to BD25 cable.
There are two other cables which can be very handy. One is a
printer modem extension cable, which allows you to place
your modem in another location. It extends your three-foot
Radio Shack cable another fifteen feet. The second cable is
the RS-232 expansion cable. This is a "Y" adapter cable
which allows you to hook up your printer and modem inline,
independently, at the same time. This eliminates constant
swapping out of cables, since the Color Computer has only
one RS-232 port. Also, as you will see later on, it will come
in handy when using a smart terminal program.
Now that you have the hardware situation taken care of.
you will need software. As with modems, there are two types
of software. The first type is known as "dumb terminal
software." Radio Shack sells a version under the Videotex
name. It is catalog number 26-2222 and includes one free
hour on the Dow Jones and CompuServe Networks. The
software allows access to these networks, but that's about all
it does. It lacks the desired features that a smart terminal
program contains.
Now you might ask. what can a "smart terminal program"
do for me that a dumb terminal doesn't? The smart terminal
program can take the information you access from a tele-
communications system and store it into your computer's
memory. After you go off line from a system, you have the

use 1200 Baud modems. You can run your printer at 1200
Baud and insert a carriage return after a linefeed.
Another bonus a smart terminal program has to offer is
that you can scroll on line or off lineup to 12 lines at a time.
Where can you purchase such a program? Spectrum Pro-
jects sells a smart terminal package under the name Color-
corn I E. (Other popular terminals include Super "Color"
Terminal, by Softlaw; Color+Term+Plus, by Double Den-
sity; and Autoterm. by PXE Computing.) These do not offer
any free time for CompuServe and Dow Jones, but do offer
the desired features of a smart terminal program. One can
still purchase from Radio Shack a Universal Sign Up Kit
(26-2224) to go on line with CompuServe and Dow Jones.
However, this kit contains no software. It can be used,
though, in conjunction with a smart terminal program.
Now that you know more about the hardware and soft-
ware which is involved, you may ask, "What else can 1 access
besides large data bases which charge for the use of their
systems?" The answer is a growing phenomena called Bul-
letin Board Services which are mushrooming all over the
United States. A Bulletin Board Service, or BBS for short,
consists of an individual with a personal computer and an

auto-answer modem set up to have outside callers access
their computer. (Yes, your own mini CompuServe!) Aside
from the auto answer modem, one needs special BBS soft-
ware to run the system. For example. Spectrum Projects
owns and operates three BBS's which totally support the
Color Computer. The three systems can be accessed by
dialing (212) 441-3755, (212) 441-3766 and (212) 441-5719.
These are operated and run on three Model Ills with a
Corvus 20 Meg hard disk drive. The system is free and no
passwords are needed to access the system. Some features of
the system are a message retrieval section, the Rainbow
Tape section which contains over 300 programs from the
pages of the Rainbow, a merchandise section, and a Rain-
bow Review section with over 100 evaluations of hardware
and software. Using a smart terminal program, you can dial
into the system and capture files from the download section.
These files consist of games and utilities which you can run
on your Color Computer. In the message retrieval section
you can leave or retrieve messages with other users of the
system. It is a way to get info on the Color Computer that is
not readily available through other channels. You can ask
technical questions, get opinions on Color Computer hard-
ware or software, and place an ad. In the merchandise
section is a list and description of products for your Color
Computer.
There is one last thing you can do with your modem.
Become a CoCo sysop! Sysop stands for SYStem OPerator.
The minimum requirements to run a BBS on a Color Com-
puter are 64K of RAM, a disk drive, and an auto-answer
modem. And of course. BBS software! (See Rainboard
elsewhere in this issue for a complete free software program
to start your own BBS.)
Bulletin Boards have proven to be very profitable invest-
ments as yours truly can attest to. Just imagine sitting in
front of your CoCo BBS and watching it being accessed by a
complete stranger at any time of day or night from anywhere
in the world! Make way for the Bulletin Board System — the
wave of the future!

By Richard A. White
Rainbow Contributing Editor
Color BASIC owners listen up. Most string handling is
accomplished using Color BASIC Commands. So when we
discuss strings and string functions, the only Extended
BASIC one involved will be LINE INPUT.
Extended BASIC and Disk BASIC owners listen up. Did
you know that the bulk of non-graphics and non-music
programming is done with keywords and functions from the
Color BASIC ROM? I wrote a program for the Rainbow that
tests a program and reports back the number of Color
BASIC, Extended BASIC and Disk BASIC Keywords and
Functions used. I was suprised how few Extended and Disk
commands were counted in programs that were designed to
run from Disk or Extended BASIC. The message is that we
can write many useful programs without Extended or Disk
BASIC.
In fact, the Tutorial Program on Strings at the end of this
column will run fine in Color basic. This is in response to
those cards and letters to the Rainbow asking for more such
programs. Tutorial programs help you learn in two ways.
First, RUN'mg the program helps some to focus on the
elements of the lesson in a step by step manner a little easier
that following text in a magazine. Secondly, those who type
in the code will see multiple examples of what the tutorial is
discussing. In either case, once you have the program on
tape or disk, it will be easy to load it into CoCo sometime in
the future and get a quick review of the subject.
We think of computing as dealing, for the most part, with
numbers. There are some programming languages whose
reason to be is to deal with numbers. While dealing with
numbers is important, dealing with characters and words
has become a major task for modern computers. Word
processing and data base management, including mailing
list data, client lists, employee information listings and
inventory all work on the computerized handling of strings.
A string is a series of characters. Characters are anything
not treated as a number. Letters, numerals, punctuation,
control characters (such as carriage return and back space)
and graphics codes are all just characters and are treate d in
(Richard White has a long background with micro-
computers and specializes in BASIC programming.
With Don Dollberg, he is the author of the TIMS data
base management program.)
the same way by BASIC. A string of characters does not have
to make sense to still be a character string.
Characters can be entered into the computer in a number
of ways. We will concentrate on program and keyboard
entry, leaving data entry from cassette or disk to other
columns. Strings may be part of a program. Here are two
examples:
10 S$="DEMONSTRATION"
20 PRINT "THIS ISA "S$
In Line 10, the string "DEMONSTRATION" is assigned
to the string variable SS. As we have said before, SS docs not
equal the string. It represents the string and allows the
computer to find the string.
Once BASIC runs Line 10 it knows where SS string is and
can use it anywhere in the program. In Line 20, there is also a
string, "THIS IS A "that is not assigned to a variable. This is
a string that basic uses when it comes to it in Line 20 and
nowhere else. Note that basic also uses S$ in Line 20 to
print THIS IS A DEMONSTRATION.
Strings can also be put in a program in DA TA statements.
In this case, the DATA must be read into string variables
before it can be used.
10 FOR X=l TO 4:READ S$(X):S$(X)+" ":NEXT
20 FOR X=l TO 4:PR1NT SS(X);):NEXT
30 END
1000 DATA THIS, IS. A, DEMONSTRATION
A FOR.. .TO.. .NEXT loop reads the the DATA into
S$(X) string variables. We then add a space to each string. A
FOR. ..TO... NEXT loop is used to print the strings and we
get the same THIS IS A DEMONSTRATION printout we
had before. Note that the program never reached Line 1000,
but found the DATA and printed it all the same.
BASIC is set up to find the DA TA wherever it is put in the
program. The obvious place for DA TA statements is at the
very end of the program where BASIC can find the informa-
tion, but does not waste time running over DA TA lines.
I don't use DA TA statements much. I like to define varia-
bles, including strings, at the end of program, send the
program over these lines once and have them available from
then on. Here is an example.

'The big value of LINEIN-
PUT is in word process-
ing and data base man-
agement programming
where all keyboard charac-
ters need to be entered
into strings."
The Extended BASIC statement LINEINPUT AS allows
entry of any keyboard character except the carriage return
[ENTER], which terminates the string. It allows only one
string to be entered at a time and does not support printing a
string after the keywords. The equivalent of the above
INPUT code follows.
100 PRINT"ENTER YOUR NAME ANDTELEPHONE
NUMBER": LINEINPUT NAS : LINEINPUT TLS
The big value of LINEINPUT is in word processing and
data base management programming where all keyboard
characters need to be entered into strings.
In the ideal program, all operator choices will be entered
as single keystrokes. Why enter a character and an [ENTER]
when we can do the same thing with one keystroke. 1NK.EYS
is our hero.
20 I$=INKEY$:IF 1$=""THEN 20 ELSE RETURN
This subroutine is a real workhouse. Put it early in the
program so BASIC can get to it in a hurry. You can then call it
from various places in the program. A good example in the
tutorial is Line 18, which lets the user pace himself through
the program.
Once the character or string is entered, it is processed or
used in some way. BASIC includes a variety of powerful
processing facilities.
Strings can be combined or added to each other in a
process called concatenation.

Here three strings were added to form a new one. AS,
which was then printed. This becomes a powerful tool when
you need to make a string that includes characters not
available from the keyboard. There is no other way to make
a string in a program that contains a quote than to add it to a
string using CHR$(34). In the tutorial program, I need to
print to the screen example lines of BASIC that define strings.
How would you write BASIC that prints the following:
10 AS-TEST STRING"
The First try might be:
10 PRINT'MO AS = "TEST STRING""
But that won't work since BASIC will read the second
quotation mark as the end of a string. It will think that
TEST is a variable, which has not been evaluated, of course,
and print a zero. It treats STRING the same way. The final
"" is thought of as a null string, a string with nothing in it
which prints nothing. If you run line 10 you get:
10 AS=0
The ASCII value of "is 34. Let's rewrite Line 10 to tell the
program to print CHR$(34), the character whose ASCII
value is 34 whenever we need to print a ". We will put the
whole thing into a new string so we can easily print it any
time we need.
5 A1S ="10 AS=" + CHR$(34) + "TEST STRING" +
CHRS(34)
10 PRINT AS
This will do the job. Key it into your CoCo and prove it to
yourself.
What CoCo can put together, CoCo can take apart. Tak-
ing strings apart, or getting pieces of strings, is fully as
important as putting strings together. Color BASIC offers
three functions that return a part of a string.
L$ ■ LEFTS (AS.NUMBER)
MS = MIDS (AS.POSITION. NUMBER)
R$=RIGHT$( AS.NUMBER)
In all cases, AS is the string we need to get something from
or take apart. NUMBER is simply the number of characters
from the left end of AS that need to be put into L$. AS
remains unchanged, and the characters in question are in
both AS and in L$. When RIGHTS is used, it works the
same way except it counts back from the right end of AS to
determine which characters to get.
MIDS is more general, and more powerful, but has only
one more parameter to remember. POSITION is the
number of characters from the left end of the string where
BASIC is to start getting characters. NUMBER is the length
of the string to get and put into MS. Did you happen to think
that we can throw LEFTS and RIGHTS away and use
MIDS for all string disassembly? The substitution for
LEFTS is simple to use I for position.
L$=MID$ (AS, I, NUMBER)
This will work exactly like LEFTS above.
To substitute MIDS for RIGHTS, we need to know how
long AS is and subtract NUMBER from that length to get
the starting position.
I00L=LEN(AS):R$=MID$(AS,L-NUMBER,NUMBER)
Looks simple, doesn't it? Well it is and it isn't. The prob-
lem is not in knowing how to use LEFTS, RIGHTS and
MIDS. It comes when you need to write the program to
calculate POSITION and NUMBER. This I cannot simply
lay out in a tutorial. It depends on the logic of the program
you are writing. Indeed, string handling functions are basi-
cally simple. It is how they are used that gets complicated.
Do not despair! Many before you have learned and come to
appreciate the power of BASIC strings.

HARDWARE
Custom Interface For The
Gemini-Id
By William R. Hall
Interfacing the CoCo to a Gemini-W line printer has not
been an easy path to tread. From bulky serial-parallel
converters to factory interfaces, there's been a price to
pay, if not in dollars, then in transmission speed. The inter-
face presented in this article can be built for less than $20
(complete kit); and transmission speeds are selectable from
1 10 to 9600 Baud. We call it the 8010 interface.
Before you decide to upgrade or backup a current inter-
face, let's cover a few bases. This interface is only for the
Gemini- 10 or 15, and not the 10X. The 8010 uses the intelli-
gence of the printer, but does not require any modification
of the printer or CoCo. If you use the printed circuit in
Figure I, you can mount the 8010 in the same place as the
factory interface and still have access to the set-up switches
without removing the case. All options and buffering of the
Gemini remain functional. In short, the 8010 emulates the
Star Micronics serial interface for the signals required by the
CoCo.
Circuit Theory
Understanding the circuit theory is not necessary to build
the interface, but for those who wish to know . . . read on.
The Gemini is capable of handling serial inputs, providing a
status word is read to set up the microprocessor for this
function. The 8-bit status word is strobed into the micropro-
cessor on pin 8 of CN2. All timing of this word is also
managed by the processor through pin 5 and pin 6 of CN2.
Table 1 shows the function of the individual bits in the status
word. The SN74 165 is used to create this status and permit it
to be retrieved by the Gemini's electronics.
The remaining electronics are buffers and signal condi-
tioning circuits. Data from pin 4 of the serial port of the
CoCo is inverted and converted to TTL levels and then fed
to pin 3 of CN2. The system busy signal (pin I of CN2) is
buffered and then sent to CoCo to stop transmission when
the Gemini's buffers are full or off line. "System BusyV is
also fed back through pin 9 of CN2.
Power is supplied by the printer through CN3 in the case
of a Gemini-10. or CNI2 with a Gemini-15, (see Figure 2).
Only +5V and ground are required to interface the CoCo.
Using The Printed Circuit
The circuit board shown in Figure I has been designed to
mount inside the printer, directly behind the serial port
panel. All components and cables are mounted on side 1,
except the switch bank and data cable. This is done to enable
the switches to be accessed through the serial port panel. The
vacant IC position and the diode pads are reserved for a
68188 line driver, for installation over 50 feet between host
and printer. Jumping pins 8 and 9 of this vacant slot will
enable operation without the line driver. Pin numbers on the
upper set of pads correspond to CN2, and the lower set
correspond to the serial port of the CoCo. The personality
jumpers shown in Figure 1 are for operation with the CoCo.
Step By Step
1) install IC I and 2
2) install RI
3) install SW1 on side 2
4) connect ribbon cable pads 1 — 9
5) connect wire to pads +5 and G
6) solder jumpers as in Figure 1
7) connect data cable (3 wire) to the pads next to SW1
on side 2 and to 4-pin din
8) install connectors on cables
9) use small mounting brackets and 6mm x 3mm screws
for mounting
10) set switches (see Table 2)

How does your computer read your mind?
How
Is
How!
Here is a cute number guessing game sent to us by
Henry Portela of Martin, Tenn. Called How, it
requires 16K and Extended Color BASIC. Although
it requires hardly any effort on the user's part, it is fun.
especially for children. The most impressive aspect of How
is the hi-res graphics used in the title page and throughout
the game. The title page is done in perspective, giving it a
three-dimensional look.
After typing and RUNning the program, press R to start
the game or ENTER to see the instructions. You will then be
asked to pick a number between one and 100 in your mind.
You will be presented with an array of numbers and asked if
your secret number is among the cluster. Respond by press-
ing Y (yes) or N (no). The CoCo will repeat this procedure
several times, using different number clusters. Then your
CoCo will "read your mind" and tell you your secret
number.
Program Line Description
Line Comments
1 speed up the action with POKE 65495,0
2 clears string space
3 — 6 letters and numbers data
7 GOSUB46 — draws title page, circles and sound,
waits for R to start the game, or ENTER for
information
GOSUB6&— draws information and waits for R
to start game
1 1 transforms the words in drawings for the screen
12 — 30 main loop
3 1 transforms all numeric data in drawing for the
screen
39 — 46 numeric data
47 — III part of main routine or loop
Henry included a high speed poke, so remember to POKE
65494.0" before CSA VEing.
How does not require skill or a certain amount of intelli-
gence. It's just a very simple math trick with brilliant
graphics.
(Henry Portela, a foreign student residing in Martin,
Tenn., came to the United States four years ago "with-
out knowing a word of English. "He has had his Co Co
for only two years and this is his first submission to the
Rainbow.)

STAR - KIBBITS
Welcome to the tenth of my monthly chats. Many of you
have commented that you enjoy reading them, and they are
interesting to write too. So here goes for this month.
In addition to having a Color Computer, do you also have
a 6800 or 6809 system on the SS-50 bus? I do, and I suspect
some of you do too. I often get a letter from a reader who
either wants to buy or sell such a system or components
(hardware or software) for it. Unfortunately, some of the
older items are hard to get, yet some of you may have an
unused one stashed away in the cellar. So why don't we set
up an
SS-50 EXCHANGE
If you have some SS-50 item for sale, send me a self-
addressed stamped envelope with a description and price
written on the back. If you want to buy an SS-50 item, send
me a postcard with a note on what you want. I will try to
match up a buyer and seller, put the buyer's postcard in the
seller's envelope and mail it back out. From that point on,
it's up to the seller to contact the buyer and make the deal.
I'm proposing this simply because I really like 6800 and
6809 systems, and hate the thought of something going to
waste in someone's cellar, while someone else is desperately
looking for it. (as an afterthought, let's extend it to anything
that is 6800 or 6809 related.) But since this may potentially
involve a lot of work for me, I insist that you follow the rules:
postcards for buyers, stamped envelopes for sellers, only
one item per card or envelope, clearly stated on postcard or
back of envelope.
Now let's see whether we can rescue some of those gems
in the cellar or attic!
AMDEK TOO
Yes, we've gotten a pair of Amdek 3" drives, and now
supply our software on Amdek disks too. Just specify on
your order. There's a $3 extra charge due to extra handling
and higher media costs. By the way, those little 3" disks are
neat.
SPEAKING OF NEAT THINGS
The little MC-10 computer is also quite neat. It uses a 6803
microprocessor, which is more like a 6800 than a 6809. I'm
sure that it's used because it contains two input/output
ports which save the expense of an external I/O chip,
interestingly enough, the 6803 has a built-in port for serial
input and output, but the MC-10 doesn't use it because it
doesn't support 600-baud operation, needed for
compatibility with the larger Color Computer. Instead,
serial output is handled the same way as on the Color
Computer, with a software routine. Though the manual
doesn't say so, you can change the output baud rate by an
appropriate poke. For example POKE 16932,245 switches
the output to 300 baud. You can try other values for other
baud rates too.
By the way, the MC-10 also has the CLOADM and EXEC
commands, though the book doesn't mention them. We use
those in our MC-10 software. Available so far are the
HUMBUG monitor, REMOTERM remote terminal
package, and COMMTERM communications program. A
disassembler is coming too.

Copyrighting
Part 3
By Tom Nelson
Rainbow Contributing Editor
Your Software
That crispy, fresh certificate from the Copyright Office
sure looks good on your wall. So what does your
copyright give you. What are your rights and what
are your obligations?
Yes, obligations. Your copyright is a bundle of rights
created by Congress which has certain requirements to be
retained. You must follow the technical requirements of the
law to obtain and retain your copyright.
Let's first investigate the rights you get with your copy-
right, registered or not. Section 106 of the Copyright Act
gives the owner of the copyright exclusive rights to do and to
authorize several things:
1) Reproduce the copyrighted work in copies;
2) Prepare derivative works based upon the copyrigh-
ted work;
3) Distribute copies of the copyrighted work to the
public by sale or other transfer of ownership, or by
rental, lease or lending.
Well, there you go. You get the right to control the .sale
and manufacture of your computer program, the translation
of your program for use on other computers and the copying
of your program. You get to reap the benefits of your
creativity — for awhile.
Your copyright is not unlimited in duration. Still, for the
purposes of the viability of your program in the marketplace
you have a virtual monopoly. Your copyright is good for
your lifetime plus fifty years, unless you are the owner of an
anonymous or a pseudonymous work, or a work made for
hire. Then the copyright is good only for seventy-five years
from the date of first publication. That's a long time with
computer programs. Even the Color Computer will be long
gone by that time, and your computer program will be
antique and quaint at best (yes, even the VIP Writer").
These rights are great and give you virtual control over
your program. I say virtual because the copyright law
includes certain exceptions to your exclusive rights. One
limitation is that there are certain "fair uses"of the program.
Section 107 of the Copyright Act states that uses of copy-
righted works for purposes such as criticism, comment,
news reporting, teaching, scholarship and research is not
infringement of copyright. As you can see, the "fair use"
(Tom Nelson was formerly a special assistant attorney
general for the State of Minnesota. He currently is
general counsel for Soft law Corporation, makers of
the VIP Library 7 '', and of ColorQuesf games.)
exception is rather limited, and applies only to a very limited
extent to computer programs, since only rarely would a
critic or scholar ever look at your object code.
This and other minor exceptions to your copyright rights
are insignificant compared to the giant exception created by
the 1981 amendment to the Copyright Act for computer
"Your copyright is not
unlimited in duration.
Still, for the purposes of
the viability of your pro-
gram in the marketplace
you have a virtual mo-
nopoly."
programs. The 1 98 1 amendment added a special section 1 1 7
to apply to computer programs:
Notwithstanding the provisions of section 1 06, it is not an
infringement for the owner of a copy of a computer
program to make or authorize the making of another
copy or adaptation of that computer program provided:
1) that such new copy or adaptation is created as an
essential step in the utilization of the computer pro-
gram in conjunction with a machine and that it is used
in no other manner; or
2) that such new copy or adaptation is for archival
purposes only and that all archival copies are des-
troyed in the event that continued possession of the
computer program should cease to be rightful.
Any exact copies prepared in accordance with the provi-
sions of this section may be leased, sold, or otherwise
transferred, along with the copy from which such copies
were prepared, only as part of the lease, sale, or other
transfer or all rights in the program. Adaptations so
prepared may be transferred only with the authorization
of the copyright owner.
This section is potentially devastating to the author of a
program and perhaps even to the microcomputer software
industry as a whole. It allows the owner of a copy of your
program to legally make an archival copy and legally alter

your program to work with the owner's special use.
This section was added to the Copyright Law after con-
siderable study, and after a special committee investigated
the relation of copyright law to computers. Unfortunately,
this committee was comprised of specialists who were only
familiar with the computers of the time, that is. mainframes.
In the short time from the late 1970's to the present, micros
have become of unprecedented importance. But the prob-
lems of micros are not identical to those for mainframes, and
the solutions differ considerably.
Mainframe computers are generally of limited quantity
and are programmed with high-level language programs.
Software for mainframes is sold in very limited quantities
and for very high prices, such as $ 1 00,000. The programs are
usually customized for the particular use and company,
either by the program designer or the company itself. Thus,
to allow copies and customization by the program owner
applies quite logically to programs written for the limited
number of mainframes. The investment of such a large sum
of money, and the special application for which the program
must be designed, make it imperative that an archival copy
of the program is obtained and the right to modify subsist.
Micros, a phenomenon new to the computer industry,
have lead to a different software situation. Software for
micros is generally not meant to be altered by the end user.
Alteration assumes a specialized use. a concept alien, by and
large, to the micro market. Micros are mostly used for
generalized purposes, for example, word processing, data
management and communications. Moreover, software for
micros is very cheap, and easily replaceable. Thus, the logic
which allows a company to make a copy to protect its
$100,000 investment does not apply to the inexpensive
micro market.
Still, the law exists, and has caused a considerable disrup-
tion of the software market. It still allows the end user to
make copies and make alterations. If limited to the skills of
users this would not be a problem.
The problem arises from the provision allowing people to
legitimately make archival copies. This "loophole" allows
companies to sell "copy" programs to allow end users to
make "backups" of their programs. If the end user had no
such right, copy programs would clearly be illegal as instru-
ments only for infringement.
It is obvious to all that these so-called "backup" programs
are not just used by the honest to make backups of their
programs, a practice approved of by all; they are used by all
sorts of persons to steal programs. Of course, the makers of
such copy programs include all sorts of disclaimers, but the
user often is not mindful of these when in the privacy of his
or her own home. The temptation to avoid even the smallest
amount of money by just making a copy is just too great.
The ability of any Tom, Dick or Jane to steal programs
rather than purchase them will eventually have two results.
It will inhibit software houses from producing programs for
a particular computer, and it will substantially decrease the
quality of programs available. There is little incentive to put
months, even years, of research into a program when you
know that only 30 percent of all copies of your programs
used by people will have been legally purchased.
So the law, as it stands, will eventually lower the quality of
software. Obviously, for the benefit of all concerned, the law
has to be changed for the micro market to prohibit the end
user from making archivals. while perhaps requiring archi-
val copies to be supplied by the manufacturer. You, as an
author, should do what you can to make sure that the

section 1 17 is suitably changed to protect your interests in
your creations.
What a digression! You've now got an idea of your rights.
Now, how to use them. As owner of the copyright you have a
few options to make the most of your program. You can
market your program yourself, you can license your pro-
gram for marketing by another company, or you can totally
assign your rights in the program.
Marketing your program yourself gives you two options.
You can either sell copies of your program, or you can
license the use of your program. Licensing theoretically
gives you more control over the use of your program. I'm
sure you've seen these types of license agreements. For
example, Tandy uses them. With a license, the end user is
not buying a copy of the program, but paying for the right to
use the programs under the conditions set out in the license
agreement. Thus, the licensee could be prohibited from
making archivals or altering the product in any way,
It sounds wonderful, almost too good to be true. Well, it
is. Licenses work well when there is a negotiated agreement
or an atmosphere of contractual agreement. These do not,
however, typify the merchandise market where software is
"sold." Instead, software is "sold" like apples or records.
You go in, see the package and buy it without any thought
that there may be some strings attached. In fact, you think
that you are buying the software, not licensing it.
Here's where a sticky contractual problem arises. For you
to have agreed to the terms of the license, you must have
read them first, otherwise the transaction must be consi-
dered a sale of the software. Thus, if the license is contained
inside the package, and the user doesn't see it until he or she
gets home, there can be no license. You agreed to buy what
you saw in the store, not what you saw once you got home.
This is why companies are now placing their license agree-
ments in a conspicuous place on the packaging so that they
can argue that you should have read it, and therefore agreed
to it. Some companies even require you to sign an agreement
before you can have the software. All this is even more
pertinent with the mail order business. You can hardly claim
that a person who orders over the phone has read your
license agreement. And placing your license terms in an ad is
next to absurd.
As you can see. licensing is not all that attractive. If you
put a bunch of fine print legalese on your packaging or in
your ad, you run the substantial risk that the purchaser will
be turned off and won't buy it. If you try instead to slip it
inside your packaging to get a "license by intimidation" it
simply will not work. Technically, the user owns the copy of
the program and is not bound by all that fine print.
Thus, many companies choose to just sell copies. You
have to make your own choice when you decide to market
your own software.
On the other hand, you can choose to have someone else
market your software. This can be done by licensing your
software for royalties or by assigning all your rights for the
software for a lump sum. Next time I will discuss the legal
considerations involved in licensing or assigning rights in
your software, and I'll discuss many of the standard contract
provisions and things you should look for.
See you at RAINBOWfest!

mative. It is not intended as legal advice. If you should

CUSTOMER SERVICE
That's right, we believe we have the best customer service
of any software producer m the industry, and this is why
WE'RE PROUD OF OUR SPEED: Over 95% ot our orders
during the last 6 months were shipped within 24 hours ot
receipt, and the rest were shipped in 48 hours
WE'RE PROUD OF OUR WARRANTY: It you EVER find
you cannot load a Prickly-Pear program — for ANY reason
(even If the dog ate it) — just send what's left to us and we
will replace it at NO CHARGE. There Is NO TIME LIMIT on
this warranty.
WE'RE PROUD OF OUR SUPPORT SERVICE: It you
have trouble using one ot our programs, just call or write
for quick help. Do you have a tape version and need an
upgrade to disk? NO PROBLEM! Just send us the tape
with $5.00 and we'll send you the disk by return mail. No
time limit, no hassle, and NO EXTRA CHARGE This is the
same $5.00 we charge for a disk version if you buy it to
begin with
MOST OF ALL, WE'RE PROUD OF OUR CUSTOMERS:
Some companies treat you like a thief! Have you noticed?
Some companies fix their software so you can't make the
backups you need and are intitled to make because they
assume that you plan to steal their product. We do not now
sell (and never have sold) a piece of software you couldn't
back up to protect your investment, and we never will.
Some software companies inconvenience you because
they don't trust you. Have you seen it in their ads? Look for
things like "no personal checks", or "no COD'S", or
"personal checks take 3 weeks to clear". They wouldn't
say that it they trusted you, and if you want to see how we
compare, look at the phrase "Your personal check is
welcome — no delay" that appears in the ordering infor-
mation at the bottom of EVERY ADVERTISEMENT WE
HAVE EVER RUN
Lately people are fond of talking about "the bottom line"
Well, the bottom line here is simply this: We want your
business. We have some outstanding programs — in some
areas we believe they are the absolute finest available —
but that alone won't do it. There are a lot ot companies In
this business, and we have gone from being one of the
smallest to our current position as one of the largest in less
than two years by following a simple guideline: It is our
intent to provide top quality products, and it is our further
intent to provide the absolute best in service and support
You've made it possible for us to grow and prosper as a
company, and we won't forget it. That's our promise.
Omni Clone
If you have a disk drive, you know how important it is to
back up your disks Virtually every book on computers tells
you to back everything up, and many recommend at least
two backups This is simply good computer practice
However, the BACKUP command on the color computer
will only handle disks with a standard tormat. so many
disks could not be backed up,
Enter Omni Clone. This amazing program handles most
any non-standard disk wit h ease. It handles variable sector
lengths, non-standard sector and track addresses, deleted
address marks, forced CRC errors, un-formated tracks,
any amount of sectors, any number of tracks(up to80), and
single or double density. Omni Clone is 100% machine
language, and it is completely self-contained. It has its own
disk drivers and keyboard scan. It uses no ROM callsat all
Unlike many programs of this type, you don't need to know
anything about the disk you want to clone, Omni Clone
does it all for you, including the formating of the destination
disk, and it's all automatic. Don't ever be caught without a
backup again! We can't promise that Omni Clone will
back up any color computer disk, but we haven't found any
yet that it can'l handle. It has even backed up some Model
III disks" Omnl Clone can be used with either one or two
drives and requires 32K to run $39.95

The Lciyzrcoorm

By Josef A. Laake
I had a strange idea for a video game one day and I'm just
crazy enough to spend hours translating it into reality
forall you fellow CoCo-nuts. Now you, too, can learn to
think like a Laserworm! Just type in the following program
and RUN h. It's pretty much self-explanatory, but herearea
few pointers. First, you receive points for your shots as
charted here:
Scoreboard
1st shot — 1,000 pts
2nd shot 500 pts
3rd shot 250 pts
4th shot 100 pts
5th shot 50 pts
In addition to shot points, after connecting five shots you
receive bonus points for the amount of time left in your turn
(as indicated by the remaining energy indicator line at the
top of the game screen). Every five connected shots increases
the level of play difficulty (as indicated in the upper right-
hand corner). This number also acts as a bonus multiplier,
so you can see that as difficulty of play increases you are
rewarded for quick shots. You are also rewarded with an
additional laserworm for every 10,000 points. (You have
three laserworms to start with and the number of laser-
worms left is indicated by the laserworm cocoons in the
upper left-hand corner.)
I have used the high speed POKE in this program, so if
your CoCo can't handle high speed be sure to delete the
following statements:
In line 26 DELete 'POKE65495.0'
In line 163 DELete 'POKE65494.0'
DELete line 200
There are several ways to lose your laserworms, but you'll
find out what they are soon enough.
So grab your joystick (right joystick, that is) and go get
those pesky fireflies! „ ,^^ >

m a BASIC program which calls the compiled
program Passing information Irom BASIC to
compiled programs is very easy In a 32K ma-
chine, the compiler leaves you a full l6Kof work
space The Color Compiler generates position
independent code so that you may put the
compiled program anywhere in memory, in-
cluding into a ROM-pack'

TURN OF THE SCREW
Build A Speaker/Amplifier
For Your Computer
By Tony DiStefano
Rainbow Contributing Editor
(Tony DiStefano is well known as an early specialist in
Color Computer hardware projects. He is one of the
acknowledged experts on the "insides" of CoCo.)
January 9, 1981; that was a great day. I bought my first
Color Computer. Today, two and a half years later I
bought a video monitor. It is a standard composite-
video monitor. It is a 9" green phosphorous screen Hlectro-
home. I know what you are thinking, "Oh no, not another
video monitor adapter!" Well, I'm not about to bore you
with another version of this adapter. 1 used one of them
myself rather than design my own. When I connected my
monitor, I was delighted with the clear, crisp quality of the
picture. I found that it had one thing missing— a speaker. 1
could not make any sounds with this monitor because it did
not have a built-in speaker. At first, I would keep my color
TV set next to it with the volume up. That was quite an
inconvenience. Well, you guessed it, this month's project is a
low cost, built-in speaker and amplifier for the Color Com-
puter. The whole thing fits under the keyboard. It even has a
volume control with an on, off switch.
The heart of the amplifier is the power IC U LM80. This is
a complete preamp and amp in one. It requires a minimum
of support parts and is quite rugged. It also has a high input
impedence. about 1 50k ohms. A high impedence is needed in
our case because the sound circuit on the Color Computer is
high impedence. If you look in the "83 Radio Shack catalog,
you will see that they say the power supply has a maximum
of 10 volts. That is not true, it must be a mistake in printing.
It can. in fact, take up to 22 volts for B+. We will be using 12
volts.
To construct this project you will need the standard pro-
ject tools things like screwdrivers and pliers and cutters
and soldering iron and solder and a drill to mount the
volume control. You will also need everything on the list of
parts. See Figure 2. All of these parts are quite common and
need not be bought at Radio Shack. As a matter of fact. I
had all of the parts in my parts bin. I have included the
Radio Shack numbers, where possible, just as a matter of
convenience. Mount all of the components except the
speaker and volume control on the Proto board. Following
the schematic in Figure 1. solder all the components
together. All the ground points indicated on the schematic
should be soldered together at one point. This is to prevent
what is known as ground loops. A ground loop is when an
electrical signal has two or more paths to gel to the same
point. This path or loop can act like an antenna, in which it

The HJL-57 Keyboard
Compare it with the rest.
Then, buy the best.
If you've been thinking about
spending good money on a new
keyboard for your Color Computer,
why not get a good keyboard for
your money?
Designed from scratch, the
HJL-57 Professional Keyboard
is built to unlock ALL the
potential performance of your
Color Computer. Now, you can
do real word processing and sail
through lengthy listings.. .with
maximum speed; minimum errors.
At $79.95, the HJL-57 is reason-
ably priced, but you can find
other CoCo keyboards for a few
dollars less. So, before you buy
we suggest that you compare.
Compare Design.
The ergonomically-superior
HJL-57 has sculptured, low-
profile keycaps; and the three-
color layout is identical to
the original CoCo keyboard.
Compare Construction.
The HJL-57 has a rigidized
aluminum baseplate for solid,
no-flex mounting. Switch contacts
are rated for 100 million cycles
minimum, and covered by a spill-
proof membrane.
Compare Performance.
Offering more than full-travel,
bounce-proof keyswitches, the
HJL-57 has RFI/EMI shielding that
eliminates irritating noise on
displays; and four user-definable
function keys (one latchable),
specially-positioned to avoid
inadvertent actuation.
Free Function Key Program
Your HJL-57 kit includes usage
instructions and decimal codes
produced by the function keys,
plus a free sample program
that defines the function
keys as follows: F1 = Screen
dump to printer. F2 * Repeat
key (latching). F3 = Lower case
upper case flip (if you have
lower case capability). F4 =
Control key; subtracts 64 from
the ASCII value of any key
pressed. Runs on disc or tape;
extended or standard Basic.
Compare Installation.
Carefully engineered for easy
installation, the HJL-57 requires
no soldering, drilling or gluing.
Simply plug it in and drop it
right on the original CoCo
mounting posts. Kit includes a
new bezel for a totally finished
conversion.
Compare Warranties.
The HJL-57 is built so well, it
carries a full, one-year warranty.
And, it is sold with an exclusive
15-day money-back guarantee.
Compare Value.
You know that a bargain is a
bargain only as long as it lasts.
If you shop carefully, we think
you will agree. ..the HJL-57 is
the last keyboard your CoCo will
ever need. And that's real value.
Order Today.
Only $79.95, the HJL-57 is
available for immediate shipment
for either the original Color
Computer (sold prior to October,
1982) or the F-version and TDP-100
(introduced in October, 1982).

would be wise to add a small heatsink to the IC. Also, make
sure that the ground wire that goes from this board to the
main board is at least 22 gauge. Make this wire about 4"
long. Now. the B+ line (12 volts) should also be 22 gauge.
This wire will go to one side of the switch on the pot. Make
this wire 5" long. The other side of the switch will go to the 1 2
volt supply. You might think this to be heavy wire, but this
chip can deliver up to 8 watts. (That is a lot of power.) The
switch-to-power wire should be about 10" long. That will go
to the B+ on the main board. The connections for the
speaker should be 24 gauge. Make these wires about 5" long.

That should be long enough to reach the holes on the other
side of the computer just underneath the keyboard. Solder
the other ends of the two wires to the speaker. There are two
more wires from the board, and they go to the volume
control— one wire to the center and the other to the left side.
Make them about 5" long. too. That will be long enough to
reach anywhere in the front of the computer.
Open the computer in the usual way and remove the
keyboard. Place the components in accordance with Photo
#1. You may want to tape them down temporarily so that
they don't move around too much. Drill a hole in the com-
puter to mount the volume control. Personal taste will judge
exactly where to drill it. The hole should be 5 / 1*". Mount the
volume control in the hole. Be careful not to break the
attached wires. Make sure that the position of the volume
control will not get in the way of the keyboard. The next step
is to connect the B+(12 volts) and ground. ITyou have the
"F" (or 285) board, find the power by looking at the photo.
It is the jumper for 16/64K. memory. Use the one marked
I6K. For the ground connection, scratch off a bit of the
green coating on the PCB just to the right of the keyboard
connector, under C59, and solder to that. If you have
another version, use Test point #9 for the 12 volts and Test
point #4 for ground. The last connection to make is the
input. That connection goes all the way to the top. It con-
nects to pin #3 on the RF adapter. This is all that has to be
done: but before you close the computer, check your work.
Replace the keyboard and turn the computer on. To test
your amplifier, any sound command will work. This one line
program works fine:
10 SOUND RND(255).I : GOTO 10
Turn the volume control on. You should hear a click. Turn-
ing the volume control up should result in some random
sounds coming out of the speaker. 100 IF SOUND = NONE
THEN TROUBLESHOOT ELSE CONTINUE. Only kid-
ding folks, but that is the next step. If you don't get sound,
check your wiring and check for cold solder joints. Make
sure that the chip is plugged in the right way. If the sound is
loud at first and drops as you turn the volume control up.
you have the outside wire on the pot on the wrong side.
Unsolder, and reverse it. Other than that, you should have
no problems.
Now, you could leave the speaker and amplifier just taped
down, or you could use some rubber cement or screws.
Don't use a permanent glue though, it could make a mess if
ever you have to remove this thing from the computer or
change the speaker. When all checks out, replace the cover
and enjoy your new speaker and amplifier.

AUTO LOAD Auto Load will put any program or file
from tape to disk! All machine language programs thai
load below the top of your disk system are modified so
thai they will operate properly with a disk system!
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 sided) 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! Compare 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 supported 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 address able me mory!

REVIEWS
SEA DRAGON
Editor:
Adventure International would like to
comment on the review of Sea Dragon in the
September issue by Neil Edward Parks.
Normally, we would be reluctant to do so,
but we felt that the tone of the article and the
conclusions drawn by the reviewer do not
remotely reflect the high quality of Sea
Dragon.
Clearly, two-thirds of the review deals
with items that have nothing to do with
game play, and by the author's own admis-
sion, he states that "Even in the Practice
Mode, I've never made the first plateau."
This, I would suspect, would be the reason
so much time was spent with what (game
play options) Mr. Parks states arc "major
faults. "Sorry ... but the game does not hang
up in the middle of play, nor does it do less
than the advertising promises. Ifthiswasthc
case, we would agree that Sea Dragon has
major faults. Mr. Parks rightfully points out
that there was a problem with how the
options work . . . but. we consider this a
minor fault. In fact, we have yet to receive a
single complaint and if Mr. Parks would
have given us a call, he would have found
that the problems had been noted by Adven-
ture International and were fixed.
Mr. Parks also states that he is not "ena-
moured of the packaging"and finds it bulky
and "awkward." He is certainly entitled to
his opinion, but his opinion docs not reflect
the fact that Sea Dragon is sold in the best
packaging available in the industry and was
designed for ease of use and durability.
Adventure International buys its hardboxcs
in quantities of 50.000 to' 100.000 units.
Therefore, the cost of our software is not a
reflection at all of the high quality packaging
we use. Instead, Mr. Parks should consider
the high cost of doing business and ask what
part the cost of advertising, printing, art-
work, salaries, color separations, royalties
and overhead play in determining the final
cost of software. I assure you it is con-
siderable.
Adventure International acknowledges
the minor problems noted by Mr. Parks, but
we feel he may not be suited to stand in
judgment of a product that he. by his own
admission, cannot play. Wc. at Adventure
International, wonder how one can reason-
ably Criticize a piece of software when less
than one-tenth of Sea Dragon has been
played.

VOCABULARY BUILDERS
Editor:
Our 32K program, Vocabulary Builders.
was reviewed in the September issue of the
Rainbow. We appreciated the kind words
that were written, but feel that several of the
criticisms were humorous at best. Great
care, preparation and much field-testing go
into each Computer Island program.
The reviewer's main criticism was our
method of randomly selecting the questions
used. I have described, in several of my arti-
cles for this magazine's educational column,
various ways of randomly selecting ques-
tions in a program. Our Vocabulary Buil-
ders program selects 50 out of 200 questions
randomly for each set. On the next series of
questions, the program selects again 50 of
the next 200 questions. This guarantees that
some questions will be repeated and some
will be new. The reviewer suggests that some
of the 200 questions may not be used after
many, many rounds. Exactly our purpose!
We extensively field-test all of our pro-
grams and have found that children easily
memorize answers in short reading and lan-
guage arts programs. After several rounds, it
is often unclear whether the child has mas-
tered the work or merely memorized the
location of specific answers. Our method of
presentation insures that new words will
keep cropping up set after set of questions to
prevent the memorization factor.
The reviewer also felt that we should have
used INKEY instead of INPUT as the
method for having answers entered. Wc
though of using that method but found it to
be unwise in this case. When field-testing
this program, we noticed that children often
hit the wrong answer key by mistake. IN-
PUT gives the child a second chance by
allowing him to use the back arrow and
change his answer before hitting [ENTER].
Wc are looking for accuracy, hot speed, in
this type of program.
Finally, one of the main strengths of our
Vocabulary Builders program is the amount
of questions it contains. Children use these
programs to prepare for various types of
system-wide school tests. The more ques-
tions and examples covered, the better pre-
pared they will become: We met that need by
preparing 32K programs packed w ith DA TA
and examples. Our reviewer's suggestion
that our program could be reduced to 4K
finally reduced all of our credibility in his
credentials.
Wc truly wish that the reviewer had spent
more time discussing the degree to which our
program actually teaches vocabulary. An
educational review is not the proper place to
state one's philosophy of education or de-
bate programming techniques. It should be
the place to report whether the program
works well on the children for whom it was
intended. In a two-page review, the reviewer
made no mention at all of his using our
programs with any children.

TALKING SPELLER
Editor:
I am writing in regards to a review of
Talking Speller published in September 1983
Rainbow, page 199. We are always happy to
see one of our products reviewed, but in this
case the review requires comment. I am not
critical of that portion of the review directed
to the actual performance of the Talking
Speller, as I feel it was very adequate. I do
object strongly to the inclusion of editorial
comments into a review, as this destroys any
pretense of objectivity on the part of the
reviewer. In this case. Professor Tchudi has
his own concepts of the proper use of com-
puters in education. That is his right. How-
ever, since the same issue of Rainbow car-
ried an article by the good professor ("The
Write Idea," page 139). I believe your read-
ers would have been better served had he
confined his philosophy lecture to his own
article. Since he did not. I feel compelled to
reply.
Granted, use of a word processing system
and a spelling checker may well be the best
method to really master spelling— for those
students capable of utilizing such educa-
tional aids. However, in this part of North
Carolina, we have very few first-, second- or
even third-graders who know how to type.
Many of them do not even know how to
operate a computer, much less use word
processing. Perhaps elementary students in
Michigan are so advanced that Professor
Ichudi's theories apply. In our case, they are
not necessarily valid. Many of our elemen-
tary teachers do not feel that spelling drills,
of whatever form, arc "trivial" or "pedagogi-
cally obsolete." Instead, they are convinced
that a student must learn proper spelling of a
few words, by whatever method, before the
students can be launched on their writing
career.
Professor Tchudi missed the point com-
pletely. Talking Speller is aimed at the pre-
school and lower elementary levels. At this
level, regardless of how pcdagogically ad-
vanced the educational system, you cannot
teach advanced concepts when the students
do not have the basic motor skills.
Happy Bits and Bytes.

Colorful Budgeting
With Color Finance
By Frank J. Esser
Finance programs on today's market run from the simple
programs to balance your checkbook and provide informa-
tion on where your money goes to those that provide a more
complete financial picture. MSI Color Finance, from Micro
Services, Inc.. and distributed by Delker Electronics, is a
program that gives you the ability to better manage your
personal finances. Properly set up and maintained. MSI
Color Finance can give you an accurate picture of your
finances at any time during the year with surprisingly little
effort. Color Finance is set up as a double entry bookkeep-
ing system, tailored to a personal finance application. For
those not familiar with double entry bookkeeping systems,
do not despair. Color Finance has excellent menus and
documentation to take you through its setup and use.
Color Finance comes on a single 5'/ 4 -inch diskette and
requires a Color Computer with 32K of memory, disk drive
and a line printer. Optionally, a cassette recorder can be
used to provide backup of the data files. The disk is not copy
protected. However. Color Finance does have a safeguard
which will discourage unauthorized access to your financial
records. A plug is supplied which must be inserted in the left
joystick port before Color Finance will run. A neat way to
discourage tampering with your records — like the lock on
your personal records file.
The documentation is of excellent quality and comes
bound with a plastic spiral binding. The manual is well laid
out and very easy to follow. It is divided into four parts:
Introduction. Getting Started, Commands and a Sample
Session.
The introduction gives a brief overview of the program
and its capabilities. Part 1- Getting Started is just that. This
chapter takes you through the steps necessary to get Color
Finance up and running. The account codes are explained
along with their classification. There are three account class-
ifications and a range of code numbers associated with each.
They are:
01-21 Asset Accounts
22-42 Liability Accounts
43-96 Expense Accounts
97 Income Account
Several examples of each account type are given. For
instance, checking and savings accounts are assets, while
charge accounts and bank charge cards would be liabilities.
Items such as food. rent, gasoline, clothing and heat would
be expense accounts. Also explained are the 75 descriptive
categories available. These categories are used to help
explain each entry made into the system. I found that, in my
personal application, 1 used only half the available entries.
There is also a table explaining how each type of entry
affects each class of account.
Part II— Commands is the heart of the manual. It is set up
such that it follows the menu presented at startup. There are
10 selections presented on the main menu. They are:
1) Daily Posting Module. Provides the ability to add
entries, print account statements and exit this section.
This module handles the entries for a given period, in
this case a month.
2) Monthly Update Module. Updates your financial
records for a given month and prepares the balances
for the upcoming month. Will also print description
summary, general journal entries, trial balance, ac-
count statements for any given month.
3) Yearly Module. Provides the ability to obtain on a
year-to-date basis the following reports: budget, des-
cription and the accounting statement.
4) Account Maintenance. Provides the ability to enter
the account titles for each of the account classifications
along with the beginning balance and the month that
balance is valid for.
5) Description Maintenance. Provides for the entry of
description codes to be used during actual data entry.
6) Change Today's Date. Allows for the entry of the date
which will appear on the heading of each report

this section in the first chapter before you initialize the disk.
The initialization process will wipe out the data in the files,
thus making the sample session impossible.
Color Finance is a well-designed and smooth running
program. The menus are excellent with clear crisp lettering
done in the graphics mode. All the menus used by Color
Finance are done on the graphics screen, thus they are not
limited to the standard 32 x 16. Instead, the screens are 42 x
32. The options are always explained and a prompt line
appears at the bottom of each menu handling data entry or
correction. If an error is made it is easily corrected.
Color Finance is a complex program and, being such,
requires more than the average effort in becoming familiar
with it. However, if you are willing to put in the time and
effort I am sure you will find the investment well worth it.
How does Color Finance provide these financial services
and how does it work? Color Finance is a double-entry
bookkeeping system tailored to a personal finance applica-
tion. A double-entry bookkeeping system is one in which a
corresponding entry is required to offset the original entry.
Thus, at any one time, the summation of all the debits will
equal a summation of all the credits, indicating that the
books are in balance. Setting up the accounts for Color
Finance is simple and really depends on how complicated
you want your application to be. If you simply want to track
your monthly expenses and not cover your net worth or
charge accounts, then all that is required is a list of your
monthly expense items and descriptions of each. However,
if you want Color Finance to track your entire financial
picture, then much more information will be needed. You
will need to know what assets you own and to whom you
owe money. You will also need the above mentioned

expense lists to complete the list. Items which would fall into
the asset category would be, cash on hand, either in savings
or checking accounts, cash value of life insurance policies,
savingand investment plans, and IRAs. Examples of liabili-
ties would be a bank loan for an automobile, charge
accounts, bank credit cards and any other open loans.
Expenses would be items like the mortgage, clothes, food,
auto, recreational activities, medicine, doctor/ dentist, insu-
rance and utilities.
1 think by now you are getting the picture. You are now
ready to create your accounts and descriptions. Data is
entered from your checkbook stubs on a month-by-month
basis. You can enter a month's worth at a time or as many
months at one sitting as desired.
1 think I write more than the average number of checks a
month, between 50 and 60. It took a little more than 45
minutes for me to get them entered for a one-month period.
The reports ran a little over an hour and 15 minutes. Not bad
considering it needs to be done only once a month.
Some of the hardest items to budget for and track are
