all I get 1* garbage.

Richard Parry, Speech Systems, owner,
tried unsuccessfully for Severn I wreU In

to do some modification programming on
Mmka 2 to eliminate the problem, 1 am
still unable to print music on my printer,
Mr, Parry also sent me * free mpy nf

after it became available. While I appre-

HINTS AND TIHS

One day you luiu on the old CoCo and
get the usual Logo on the screen. You sit
down and prepare yourself for a lew hears
of enjoyment and go to enter a command
on the screen, then . . . panic stations! No
maiier what yon dn, nnihing will etucr uu
the icrctn. No line numbers, no list
command, no directory rrtiumund nothing
— just the cursor on the screen.

In a wild pnnii: you lIiclI alt the electrical
connections nil light and plugged in, All
connections 10 die priuici, tape dciA, disk
drive, etc, — all tight and plugged in.

Yuu shut the machine off and an
nothing. You even disconnect the disk drive
(after shutting the machine off, of course)
and even the primer, to no avail. Still only
the logaj

"Oh, no I Nat a chip!" you wail in horror,
"not b long down lime, not now!"

seem to grow around the machine, and ihe

of the books and woe depressed.

When this happens, the computer will not
accept any keyboard input at all tat least
not the new 64 K version).

Try it. Hold the ffrebutton down and ley
to type something. Hope this saves some

Aboui three veins ago, give or lake a few months, a fellou by
the name of Wayne Green figuratively "shot himself in the foot"
by predicting the Color Computer was "dead" and would be
discontinued by Radio Shack. That article was accompanied by many
pious suggestion* for Tandy personnel on how to make the CoCo T s
successor survive

U there a "Peterborough Plague' 11 Thai inflicts resident* of thai
picturesque New Hampshire hum Let eveiy l luce years or so? Lt seems
so to read the latest from Michael Nadcau, who de spile being editor-
in-chief of a magazine that supports our CoCo T states flatly "The fact
is lhai most people don't need computers, and the computer industry
has I at led to come up with a good reason for consumers to buy one."

Nadcau*s column, "Digressions," also includes suggestions for Tandy
Corp He concludes "ft really is no wonder that the home-compute r market
ts dead in the water."

Michael uses the same word — *dead" — and makes the same mistakes
as did Wayne, who was founder and publisher of SO Micro.

Interesting.

Gee, Michael, 1 don*t know what you are using your home computer
for (unless you're trying to raise turkeys or something), but I have a
whole lot of uses for mine and keep finding new ones, too.

You make light ol checkbook balancing programs, but 1 keep mine
balanced with my Ironic computer. Also, 1 have a lot of hooks, and t
have ii really nice dai abase set up with my ToCc? to keep track Of where
they all are. And, my daughter weni from a t C 1 lo fin 'A' in French
in one six- week period just by using a little program f wrote myself on
Lhe Color Computer.

THE rainbow gets literally dozens of program submissions each week.
Usually these arc programs people have written to use at home. In short,
Michael, I think you, just like Wayne did several years ago. have sold
the CoCo and other home computers short.

1 remember thai f was putting out a prclty brash little newsletter when
the "Peierhoiough Plague" first struck and 1 wrote an editorial suggesting
to Wayne that if he didn't like the CoCo, he should leave it alone He
did for a time s but then apparently saw the error of his ways* and ended
up starting a magazine to support it.

A lot of people never forgave Wayne Green for declaring the Color
Computer to be dead. More than that, I wonder whether people should
he in the Color Computer-supporting business if they don't believe in
the product in lhe frrsi plan*

Granted, there are slower sales for CoCg righl now, but we sec new
software coming from Tandy arid from third-parly sources as well Wn
see an excellent computer system in place. We see a new CoCo on Ibc
horizon that will run circles around the competition. And yes, we see
our own business as good and the CoCo market as a strong and healthy
one.

Here at THE RAINBOW, wc like the Colo; Computer just fine.

Mom has saved just about everything I Ye ever written. Which,
considering all the time iVe spent writing things, is quite a lot of stuff.
Rut, in all that time, she \ never written anything (except letters) — until
now.

Mum's first journalistic effort is reproduced below, I know it dotsn 1 .

But, she's my Mom and it's her "first" article ever,

BUILDING OCTOBER'S RAINBOW

Pyramid Pow{d)er . . .
The KainbowTech Disk * . ■

Nearing tlie Billion-Page Mark , » .

Since this is, after all, a "building" mJi l, let \ liiscuvs l hrt Litest building
theory I came upon ii in the June Reader's Digest, U seems a sciential
now claim* thai the pyramids may have been built out ol concrete!
1 kid you not; that's what he says and, so far. I haven 1 heard anything about
his being disproved.

Concrete! Give me a break. If chemist Joseph David oviis of Barry University
Ln Miami Shores, Fla, r turns out lo be right, he should get a handsome award,
but the rest of the geologic* ami archaeologi\i\ wliu've pondered the "riddle
of the ueniuries" should turn in their pith helmets — or be ridden out ol
town an a rait. Scientific hint: Look tor some initials in the corners oi the
blocks, guys.

Legions of slaves heaving countless six-ton Limestone slabs, indeed. It may
turn out that the oldest of the so-called seven wonders of the world was
built using a team of camels pulling a ready-mix wagon Daviduvit* believe*

the pyramid builders filled wunuV nlds with a slurry of crushed limestone

niiard with a mineral binder. In fact, this theory may explain why the pyramid
Clones sire filled with liny air bubbles not found in the Quarry Irom which
they reported I > curac. Don\ as k me why ihe hijzh priests Of the scientific
temples cen t tell man made poured cement from natural rock, but 1 can't
say I'm DOt surprised, because I am. This shakes up some old foundations,
including my belief in science as a science.

If this cement theory holds logei her, move over Filidowtt Man, because
this guy may have uncovered the Hoax of the Ages, Stretching across the
centuries for a segue, I'd like some concrete ideas irom you renders on how
to .solve a problem thai seems to be pyramiding here at THE RAINBOW h You
see, we're considering something I've tentatively dubbed the Rainbow Tech
Disk, a new service, and we'd like to do it right the first time.

Often, we get letters asking why we don't put assembly language source
Code on ka l in HOw ON TAPE The miwi rre.cn I pita comes from Jacques Lahonle
of Act on Vale, Quebec He makes a good ulsc fui providing source code
on magnetic media, 1 agree that there's a need, but 1 don't think RAINBOW
ON TAPE is the vehicle. Ol the thousands who avail themselves of I his serv ice
each month, loo many arc rank beginners who would pull their hair out
trying to CLDRD and RUN source code. No, they need the assembled, running
binary file — only, There's more to it than that, though.

Others are asking regular iy when we are going to offer OS-9 piiiginmt
ready to load and run. Can't do ihat mi tripe, can you? Al least, not readily,
Besides ihat T si ill oilier* want templates for spreadsheets and database
ttrxuagrrv ami the growing following of "CoCo Gallery** wants these picture
data files ready to load m and view, but many of these are very long and
useful only to those who have the programs to load them. So* there is a
wide variety of programming material -- some I haven't even mentioned —
we need to package io tome convenient way.

Enter the ftpinbawTt'ch Dhk, n sort uf high-ledi «rvice for sj>cciaiiK:d
interest*, a diversified magnet ie iLs^eiublage of computer odds and ends- I low
to do it? Well we Have a couple of avenues for getting both US-V and Lhsk
BASIC files all on the same disk, without even flipping the floppy* but then
maybe you know a belter way. Also, is this something you'd like io have?
And, whal els* Would you want on this "hard-core hackers" service? Let u&
hear from you. ai this point* nothing is carved in si one

To this brief treatise* my usual footnote: Join the legions ol rainbow
sttbsciilicis and well order our scribes to parcel tfut, juai l&r you, u ^peciaJ
monthly ration of the almost 3(X>,tW0,WX> pages we prim annually — almost
a billion pages since we launched a four pace newsletter in June J 98 1.

By Bit! Bernico

Sesame Street teaches f unda-
mentals to youngsters, help-
ing them understand simple,
everyday words like large or small,
near or far, alike or different.
I lerc's a program that helps them
comprehend up liuu down.

This program, Elevator, at first
glance T may appear to he strictly
for young kids. Don't believe ill
There are some pretty slick pro-
gramming tricks integrated into
this one — tricks you may want
to use in your own programs even
if you aren't overly entertained by
an elevator making the rounds.

Constructing the seven ttnors ol
the building is done in lines 80-
220, the building being topped off
by the word "ELEVATOR" in
Line 230. Lines 240-250 ask if the
user wants to go up or down. Lines
260-290 accept use; input. Line

tSili Bernico is a sclf-iaught compuivrtsi
who enjoys golf, music and program-
ming. He is a drummer with a rock hand
and lives in Shtboy#on> Wis )

270 keeps the words "GOING U M"
on the screen and erases the l> OR. M
Line 280 keeps the word
"CniNCrnnthe first line, erasing
the rest of that line. It also keeps
the word "DOWN" on the second
line, erasing "(U/D),"

The basis of the elevator action
is held in lines 300 through 420,
Lines 300-350 are GOSUBed if the
user chooses T>' and lines 360-420
arc finsUBed if the user chooses
V\

In either case, *S* equals the
value of the sound, with the tup
floor having the highest sound, *W
equals the number of the door
displayed in the right window and
is poked into value *V\ t used POKE
instead of PRTNT P because PRINT B
left unwarned spaces before and
after the number.

As the elevator passes each floor
a character string that's half black
and half yellow appears in the
window, which gives the impres-
sion of the elevator being halfway

Uncomplicate
Programming Tasks
Using Your
ROM Routines

By R. Uarlly Bella
Rainbow Cunlributitig Editor

I recall a saving I used to hear. The
situation Wffli like this;
If 1 wanted to borrow my friend \
yoyo, I so id, "Hey. Bryan, can I burrow
your yoyo?"

He kindly replied, u Ah, go gel your

own, dummy,"

I said, "Why buy a cow when you
can milk one through the fence?"

He promptly hii me on ihe jawbone

with his yoyo.

You Bouf hi it with Your Computer

Well, there are a few things you con
borrow from your computer, without,
endangering your jawbone. They an
tailed ROM routines. Remember? 1
men tin ncd ihem in (he August column.

A ROM routine if a machine lan-
guage ruutmc thm resides in ROM.
Actually, your computer's KUM
{Read-Only Memory) is nothing but a
series of machine language routines and
liibtcs. Some of ihc routines only
operate as part of the a*Str ROM built
into your computer, but other routines

(R. Berth Bern ts currently a technical
writer for Tandy Corp. and i* a former
news reporter and magazine editor. As
the father nf If) rhitdrvn, computers are
his ejtape from leutity.)

can be called irom any program and
put to use.

itu kainbow has carried numerous
articles and listings dealing with ROM
tiiutitfo Hnd I do net propose to
compete with theux However, I have
talked to a numbej of people who, «fter
looking over the articles, still didn't
know of what value they arc or how
to put them to use.

Along with ROM routines, your
computer also com aim some tables and
value* in a " wurk space" area of R AM
that can also be borrowed atkJ manip-
ulated to make assembly language
programming a bit easier, I will leave
i hat discussion for the future.

Xtr ROM Routine* Worthwhile?

Dcfore encouraging you about ROM
routines. I should mention thai using
them is not always the best policy Ynu
may have experienced the frustration
of having a program thai works on one
version of the Color Computer, but
docs nut work properly on another
version.

Often this is due to a change made
in the ROM routines that the program,
attempts to directly ucees*. Candy, of
course, does not guarantee it will leave
ROM routines alone in new versions

of basic. Thus, using them can create
future problems for you or someone
cist.

A good example of this type pi
problem is found by attempting to use
the Telewriter word processor with the
JDOS disk controller. The JDDS
controller contain* its own Disk BASIC
routines, and Tekwrtter relies heavily
on using built-in Diik basic It does
not find what it is looking for in JDOS
find, as a result, cannot function. A
machine language program that is
totally Independent of ROM does not
have this type of problem and could
j»>Miihty operate on a totally different
6809-bascd computer.

Despite the problems involved in
using ROM routines, it is still a fun
way id program. There is something
exciting about doing a com plicated task
wtih very little programming. For
instance, There in a ROM routine
available to clear the Icjli screen and
home the cursor To ti.*r il, yon need
only one program line:

JSR JA928

That'*; all. Routine 5A928 clears the
screen and sends the cursor lo the top
left-hand corner of the screen. If yuu

Odotxj' THE RAIHBOW 29

wish to check this out from BASIC, type
FVFJC *HR*3?B and FKTFR T> « more
wml t1iu.ii typing CL5 and pi cuing
Enter, but it does the job. From
assembly language, however, such a
routine is much less work thaw writing
the code to do the job. For instancy
the code to only dear the screen might

Anytime sis lines of code can be
replaced with one it seems like a guud
nfttft9$$ However, I he onc-liiicprogniui
would never work in a 64K machine
with BASIC ROM disabled, The six-line
program possibly could.

The Son of Bytecotttr

I lvoa pleasantly surprised at the
in Iciest in the By (a odvt program of
some months back, If you remember,
it is a BASIC program designed to allow
you to examine and change memory
locations, lis purpose is to let you enter
a machine language program without
the use of an editor; assembler One of
its feat u i cv is the ability to save the
machine language program once you
have typed it.

t have gotten a lot of letters and calls
as a result of the program. Some wanted
lo say they enjoyed I he prugiani and
round it useful (thank you very much),
and others were having problems. Also,
a couple o| readers altered help and
suggestions.

To Richard D. King of Houston,
Texas., and Larry Geiger of Lawrence,
Kan., I give thanks Your stiggcsiron>
and upgrades arc appreciated and arc
included in my new version. For those
who wanted some way to examine
registers in BASIC, I nave included the
feature in the new version of Bytecoder.
The interest in Bytecoder seemed keen
Enough that t decided to upgrade il and
include a\\ of your ideas and sugges-
ting, ynur corrections and a few other
goodies.

What if Does

Bytevodvr now has ihrre displays on
the screen when you are entering or
examining code. Instead of just the
hexadecimal values of the memory
Locations being displayed, you also see
the decimal values and the ASCII
characters these values represent. If an

ASCI J v , A\u: i .1 m ji.ii h*' di^pl lived uu i In'
Screen (it is less than 32) then the display
shows "XX."

I have included the decimal display
for those who arc still not familiar with
hexadecimal. I have retained the
requirement that the values you enter
are in hexadecimal due to I he faci ih.ul
ibis is what most assembly language
listings show.

1 have included the ASCII characters
to allow you to read any text located
in memory.

Thanks to Mr King, Bytecoder now
adds an extension tu the filename if you
air utingrUsk T? also provides* prompt
that asks if you wish to save the
program to tape or disk and then acts
accordingly. As well, Mr. King included
some lines to trap filenames that are
too long or if you try to save a file
without a file name.

Mi CJeiger provided the solution to
the problem of wrong values being
displayed if a number less than 16 is
entered. The change is in Line 630 for
those who have been trying to track It
down yourselves.

As mentioned earlier, Bytfivder now
Ids you examine the registers from
basic The process is accomplished
through a machine language program,
but it is accessed by basic, so you need
not leave the program to use the
function.

Other chunges are mostly cosmetic
find have little hearing on how the
program works. The new lines have
been inserted between the old Lines so
you will have little difficulty in spotting
them to add to the original program.

Purring li to Vie

To use By winder f alter you have
typed it in or loaded tl from RAINBOW

starting address prompt with the
hexadecimal address ol where you wish
to examine or change memory. The

To move ihe cursor eighl bytes at a time
(to the next row above or below), use
[he up- and down-arrow keys, Use the
equals sign {-) or minus sign H
to move the display back 24 bytes, or
the plus sign (+) or semi -colon (;} key

quite satisfactorily without It

1 have tried to keep Dyiecadcr simple
to use but gave it the features it needs.

I have included the complete code in
Listing I heed use of the extensive
changes thai nave bren made.

As well, the assembly sunn* cude for
the register display function is included
as Listing 2- You may wish to put It
to use in other programs. All that
Listing 2 does is store the register values
in memory locations S7FF8 through
S7FFF I then used peek to obtain the

values, put them in a string and display
them (see program lines 840 through
950). You must use CLEOR I,4H?rC0
to protect the program and its values

"This game is for naturally mellow folks who
accept success as the reward for
perseverancQ , . . "

NO NINES
ALLOWED!

By Richard Ramella

To-nmcr is an innocent little listing. lt\ not
f^LJ rnuch trouble to type in and run. Riti
J. T beyond that, ifk » tricky test of your
thinking ability. Same players have been known
to never heal it, IT you want to consider that at
a dare, then do*

My best score h 39, so that's the score you should
equal or try to beat. I think a score of 40 or more
is impossible, but I hope someone proves me wrong
(If so, Td like to hear about it.)

When you run the program you Ye presented with
an cight-by-cight grid comprised uf all letter O's,
except for the *X* in the northwest comer. To start,
move the *X' to the position where you want to
begin. Tap the 'A 4 key for north, 'Z T key for soulh,
comma key for west and period key for east, When
ready to start the test, press *P* for play. A numeral
T appears in place ol the 'X' and youVe scored
one point.

From this start, directional moves count upward
to *8\ then start over al *V Every move you make
scute* a point.

Of course, there 1 * a catch. At any time during
play, ihe g»me ends if any two numbers in a vertical
row total nine or more. For example: At the start
you press *P' for play when the *X* is in the northwest
corner, Then, pressing the period key seven times
counts from *2* to *8\ ending at the northeast comer

The Analog-To-Digital
Converter, Part 1

By Tony DiStefano
Kninhow Contributing Editor

The world inside your computer
consists of zero* and ones — all
thai goci on inside your cumpu'
ter hinges on two values. Memory,
PIAs, CPUs, VDGs and SAM chips all
transfer information between each
oiher using only two different si Kiev
These Males are called logic Mute*

The firet logic state is zero* also
known aa "low" or "lo.^ In the Color
Computer I and most computers la logic
ttale low is zero volts, also known at
ground level. The second logic state is
one, also known as "high" ur ^hi "
Again* in (lie Color Computer, a logic
stare high is five volts, fx re pi for
specified tolerances, ail other voltages
in between are undefined and if encoun-
tered can Rive ihc computer some
unpredictable results. This is the digital
universe of rotnputrrv Figure I ihuw*
a typical digital wave foiiii.

The. real world, however, deals in ever
changing states. Digital ones and zeros
are just two of millions of different
states thai exist, The real world is an
analog world. A good example of the

analog world \s speech. You can Apeak
loud, you can speak low or many levels
in between.

sound waves are ever changing* i-or
example, if you lake a microphone and
amplifier and hum into il, the speaker
will vibrate, reproducing the sound you
are making. That vibration is a hack
and forth motion. The frequency of the
back and forth motion depends on the
frequency of your hum. Frequency is
measured by how many times a wave
form goes back and forth in one second.
Every llrae the speaker move* back and
forth \k one cycle.

From 1886 to 1888, the work of
Hcinncb Rudolph Hertz led to his

discovery of electromagnetic waves,
Ihc Uerman physicist's revelation
opened the way for the development ol
radio, television and radar. As a tribute
to him. ihc frequency of any wave, be
it digital or analogs is measured in hem
(or H/ t for short). In ihe audible range,
the frequency La from about 20 H/ to
20,000 Hz or 20 kite. The V stands
for "kilo" meaning thousand. Our
CoCos, for instance, run at K94 h UU0 Hz
or .9 MHl The *M' stands for "mega"
meaning million.

Figure 2 shows a graphic rcprescn-
taiion of the output of a *nun® wave.
Compare it to the wave form in Figure
I. There are some obvious difference*:

42 T*£ RAINBOW OclQC*r lftflS

Jl U t hese differences thai make H
impossible for a computer 10 directly
nad ncmr airly rend and duplicate hji
analog wave form.

Don't despair, there art ways around
it I his is the first of a two-part project
on how you can use a computer to
measure analog signals. This project
stems from several Letters received from
my i e.ule i s ic\|i]fMing rliai I build .t
computerised oscilloscope adapter for
the joystick port, 1 looked into the
joystick port as an input, but found it
to be inaccurate or not fast enough. By
i he iime you finish reading this, you'll
know why.

Anyway, lti« month well cover the
theory on how a computer (and a lit lie
hardware) can convert an analog signal
to a digital value. Next month well
cover how to build and calibrate the
analog to digital convener.

Now to the task of explaining how
n computer can convert an analog signal
to a digital value The first thing thr
computer needs is some hardware, a
comparator. A comparator an !(." that
has two inputs (the "positive" input and
the "negative" input) and one output.

The output has two states; on or oii.
good for a digital computer. The inputs,
however, have analog inputs.

Here is how a comparator works.
When the positive input voltage is
higher (more voltage) than the negative
input, the output is high. When the
positive input voltage is lower (less
voltage) than the negative input, the
output U low Figure 3 shows a block
diagram of a com puler-uonl rolled
comparator,

The way it works is simple. If we had
d known voltage at the negative input,
by reading the output (high or low) we
could tell If the test voltage at the
positive input is higher or lower than
our reference vnltage. Furthermore, if
wc change oui icfeicnee voltage and.
zero into the unknown voltage, we will
then know what the unknown voltage
is* This technique is know n as jiucccuivc
approximation.

The ptrurdufe for succeiiiivt approx-
imation is as follows: Start by putting
half of the maximum voltage your
device can measure to the reference
voltage. If the output of the comparator
is high, ihat means the unknown voltage

OUTPUT

is higher than the reference voltage . We
then increase the reference voltage by
half the difference of the present value
and the Last value and test again. If the
output of ihe comparator is Low, thai
means the unknown voltage if lower
than (he reference v ullage. We would
then decrease the reference voltage by
half the difference and test again.
Continue to do this until we have
reached the unknown voltage.

Let's take an example. In this exam-
ple. I round off the reference voltage

lo I he neare&l whole number for ra.w
of calculation. The maximum vnltage
is I DO and the unknown voltage 47. Thv
first reference value is 5U loo high,
so we subtract from the present value
using the successive approximation
methodi . New reference is now ( 1 00-50)/

1 »i 5ft- 25; ihe new reference it 25 —
loo low. si.i ddil, The new icfcieiiLX
is now (50-251/2 or 25+13; the new
reference it 38, still too low. Add again.
(25 28)/ 2 or 28+7, The new reference
is now 45, again mo Low, Add (53-45)/

2 or 45+4 and l he new reference is 49,
TrmlV too high. <n uifalrwl (44-4S)/
2 or 49-3. The new reference is now
4b, which is too low, so add (46-49)/
2 or 46+2. The new reference voltage
is now 48. Too high, so substract (49-
48)/ 2 or 4$~L We have now reached
the point where our reference voltage
matches I he unknown voltage.

Actually, the rounding off is not
limited to integer calculation, but rather
to the resolution oL the reference
voltage. When zeroing into the
unknown voltage, you divide until the
unit change in voltage Is one. You
cannoi divide and get a more accurate
fix on the unknown value. Ho matter
how dose you get, the comparator will
always give a higher or lower value. I he
more murine the reference, the closer
you get to the real value of the unknown
voltage.

This reference accuracy is one of ihe
reason* why 1 chnsr. nnl ta use ihe
joystick input. You sec, inside the Color
Computer there is all ol the previously
mentioned circuitry; a voltage compar-
ator, a variable voltage reference, an
unknown voltage input (joystick) and
the interfacing circuit to control it all,
A more common name for a variable
voltage reference \i "Digilal-to-Analog
Converter" or UA<J for short. Ihe
UAC inside the UoLo is limned, it has
a fixed output of .2) to 4.75 vol is and
the resolution of about 0.07 1 5 volts.

I he range is not very gnoil fm iin
analog to distil project.

Another rcojon lor nut using Che
joystick input is speed. You see, the
successive approximation method

Iced about earlier is Lime consuming.
The. CPU hits iu calculate the next
reference voltage vh I iicr.sel uplhe DAC t
read (he comparator nuipui ami make
the proper decision.

The speed at which an unknown
voltage can be found is very important.
When the unknown voltage b stable
and noi changing, the compuier can
rake fill the time in the world to figure
out what the voltage is. Rut, if ihe
unknown voltage is changing, like the
humming mentioned earlier, speed is
important.

The amount of time U lakes the CPU
m <rfher Jcrvitre to find an unknown
voltage value is called the "conversion
tunc." The faster the conversion time,
the more samples can be taken and the
more accurate the wave ahapc repro-
duction can be. For example, a I you
have a I nop to read the A to D converter
which lakes 10 ms (ms ~ milliseconds
* 1/ 1000 sec ci mis), itini menus you have

100 samples per second. If you are
sampling a w«vc form thai is I ♦000 Hz,
yuu will truss h hit of inform at Eon, II
is safe lo say ynu need .U Ir^i 10 Eimcs
the sample rate to reproduce a panic*
ular sine wave with reasonable
accuracy.

A basic loop using the J0YSTK
command will limit you lo about 3 Hz
— uul vny faai. in machine language,
you can get n In I ix\Wt. but ii is mil
slow due tn I he overhear! rreaird by
the CPU having to do the conversion.
In the case that the CPU has an external
A lo D converter, a great increase in
tipeed and accuracy can be achieved.
Whh the right software the effective
conversion rale fur an external A to
D could be as high as fiOfl 1>r/i/

the Last thing I must mention this
month is that the A to U circuit requires
negative voltage. I his is no problem
with the first CoCos. but U is with the
CoCu 2. The CoCo 2 has no negative
tuliagu available si the cartridge
connector, There i*> however . negative
vollagc available inside the CoCo 2

To bring this voltage lo the cartridge
connector is simple; you just need one

piece of wire and a soldering mm Fuse,
unplug the computer, then open it and
locate the chip with the number
SC77527; this is the SAL I chip. You
will find - 1 2 volts on pin 1 5 of this chip
(just what the doctor ordered), Solder
unc end of -a piece of wire to that pin.
Locate pin ff I nf I h e cartridge connector
(it is the lop pin dunes! tu the hank
ol the computer) and solder the other
end of wire to this pin Bel ore you plug
anything into the computer, measure
ihc voltage to thai pin. It should be
*ibom -12 vohs T give or take two volts.
On thr CoCo 7 ihh pin is normally
not connected to anything On ihct
regular CoCo, this is the regulated
12 volt pin. lhe -12 volts you just
added to that pin are not regulated, but
in this and most cases, it will not matter.
Tli trie will be a negative voltage reg-
ulator nrt the A lo T> convenor Of all
the peripherals I have seen for the
CoCo* only one uses the negative
voltage and U doesn't matter that it is
not regulated,

[f all is well, close your computer and
111 we you next month with Pan 2 of
the A in H converter fSSi

There arc quite & lew punctual ion
marks in the preceding paragraph.
Using punctuation marks correctly was
almost becoming a tost an until
recently. The "back to basics H move-
nirnl occurring in many \chr»nl sry^iems
has included stressing the teaching of
written expression. The proper use of
punctual ion murks is an esse n lid part
of this skim

Punctuation Quiz reviews the uses of
punctuation murks. A chart is displayed
listing major puniliiitrifin marks And
Shows thcii keyboard symbols. The
student is i hen quizzed on when to use
each of the marks illustrated on the
chart. The mud Bin's task is to type in
the answer to the computer's questions.

it proper, in this case, to require the
correct spelling of names of the punc-
tuation marks. This is always a difficult
decision to make when writing any
educational program. It presents a
douhtc-edgeri sword On hue- hand, we
always prefer to leach correct spelling,
on the other hand, a child often feels
cheated if he knows the correct answer
but misspells it and gels marked as
wrong.

We compromised on the issue this
time. Fx act spelling is (he only way to
get, a correct answer in tlii* pttigr&in.
I he pressure is eased, however, by
omitting any scoring in the program.
White wt 1 do wont the children to learn
lo spell words correctly, we do not want,
at I he same time, tu penalize them too
severely fnr minor spelling tuislaLes.
After each group of five questions, the
student may press "C to continue or
'E* to end the program. Ihe program
may be played continuously until the
student leams all of the mark*, in the

}HUgJHttt.

Punr t not ion Quiz al%« helps lu
f amiliarize children wiLh the keyboard ,
typewriter symbols. Punctuation marks
are often contusing to beginners
because the SHIFT key must be used to
product some or them. Fortunately* the
GuCoV keyboard U very similar to that

of a Standard typrwriirr More than
halt ot the punctuation marks are in
similar positions, Many other compu-
ters have keyboards that are quite
d iff e rem from a standard typewriter
keyboard.

Beginners should he encouraged lo
gain familiarity with using all of the
CoCo's keyboard symbols. The only
odd punctuation marks we have ore the
brackets. The left bracket is made by
sijmdianeously pressing the shjk I and
down-arrow keys and (he right bracket
h made b) pressing ilie sutri ami righi-
arrow keys. (1 have trouble remember-
ing this myself and always have to check
it out first.)

Line 50 reads ihe DATA statements
necessary for the chart. Line 60 reads
the DATA date menu for the questions
and answer*. Lines 70-100 print out the
chart of quotation marks and their

symbols,

Lines 190-320 contain the quiz. Line
210 randomly selects one of the 11
possible question and answer sets. Line
220 prints the chosen question, Lines
260-270 check hi sec * he then he answer
is correct. If it ts incorrect, the correct
answer will be displayed.

After live questions, the student may
begin again or end the program by
pressing either the letter "C T or 'b T . J ne

routine on lines 32U-34U takes care oj
this task, A record of I he student's score
could be added between lines 320 33®
if you desire one. This can easily be
ach i«ved by iaciementing a counter on
t\nr. ?M Tnnrhirvr M»k mU\ r®=rp+i
at the end of Line 260,

Each tunc a question is answered

correctly, the counter will increase by
one, You could then create a line such
us 3<th PRINT CR:CR-e. this would
indicate the score and reset the count
to zero for the next round.

A* ducrussed earlier, we did not feel
the need foi a xcoicVHfd in thii par-
ticular program. The choice, nf niwrw,

is yours. As always, please feel free to
allrr this program as you see fit to help

Computers Can Play
An Important Role
In Art Education

By Michael Plog, Ph D,
Rainbow Contributing Editor

When dealing willi compiiTn s
and education, the subject
matter area ecu ins the short
end of the electronic stick Li the urtv
This is understandable in some ways,
but really doesn't malce much sense —
fnr the Ati% rn foi education.

In general, elementary schorls ustr

computers most frequently with math,
fallowed by language arts, readme,
computer programming, social studies*
science and then art. (This is a finding
from the National Cam mission for
Employment Policy. "Use* of Compu-
ters in Education," conducted by
bducalion Turnkey Systems. Inc.) We
eao easily understand why computers
are most frequently used with mat he
marks. After all, computers are
mathematical calculating machines,
and math tfiacticrrs have been trained
in such things as calculating mauliinc*,
Art teachers arc creative people who
deal with such things as paint, clay or
other products.

Of course, the concept of "art* covers
a wide range of activities. There arc the

(Afkltael Plog received his Ph. D. degree
from the University of Illinois. Hr hm
tuughT aortal studies in high school,
worked in & central office of a school
district and currently is employed $t
the fflinais State Board of Education.)

performing arts, such as dance, theater,,
minis, nt<igu-. music and so on, Com-
mciual ait cover* much things as
photography and drafting Some
schools even include I tlm making in the
curriculum*

The amazing thing is that in most
fields of nri the com pater has been used
by professional arttE.li, but not in the?
schools, whoe students are usually
introduced to the arts. Much of the past
"computer art" depended on the ability
of the computer to produce random
numbers. Then, a song or painting or
some other artistic product was created
using the random numbers.

The random effect has hi-.cn used in
the past with some degree of success
Mo*art fin 1777) composed a piece of
music by using dice to help pick a scale.
One hundred and eighty years later
(I937) T Lejaren Hiller and Leonard
Isaacsori composed the "Iliac Suite for
String Quartet" using liuinVwi number*
generated by a computet. Genet ally,
however, the random number approach
to art results in a product that is
appreciated only by the artist (if that
much).

There is much more to computer-
assistpii art (and an education) than
random numbers. We listen to a lot nf
computer music. Moog synthesizer and
electronic guitars are commonplace
today. The computer provides not only

the music, but in some cases h provides
the structure of a piece and relieves the
artist of many mundane tasks, irom
writing musical notes to reading them,
Vangclis, who provided the score for
the movie ChaihitA of Fire, cannot read
music. But. he can generate art.

Computers are used to help in all
kinds of animation, from Saturday
morning cartoons to commercials. In
fad, were it not for computers, we
wnuld have mnrh Iris animation today
than in the past. Salaries have Increased
a lot since Watt Disne y direc ted a tea in
of animators.

Computer-generated graphics are not
only used to present subatomic particles
and the structure of DNA (which looks
like an to me), but pieces that hang
in museums. Computers have been used
to analyze the movements of dancers
and runners lor training purposes. John
Swart z welder has even used a CoCo to
create one-line jokes (example: Scien-
tists discuvrr new moon orbiting Rate
Smith). Computers have been used to
mathematically analyze prose Had
poetry of great mailers and then mi nin-
th at style to product? ( some not so great)
literary efforts.

So, if artists use computers* why
should art sett dents noi be using them?
There arc scvetal reason*. First, we do
nut expect students, rsprrially elemen-
tary students, to produce grcai woi k\

October '005 THE RAINBOW 55

of art, We expect them to learn about
art instead of attempting to compete
with profession fits. Second, moat of the
computer jippkcaiions mentioned here
involve rather sophisticated software,
which artist* are unwilling 10 share with

group of elementary students. Also,
there are few software puhVtsher* wlin
provide computer-assisted Instruction
puck apes (still the mryu frequent uat of
computers in schools) for art. Finally,
art teachers may not realize what
student? can do with the help of a
computet

I hold the position thai students —
even in primary grade* — can «w inr
computer to help them learn about the
arts, f believe students should learn art
by actually doing it, Thev should learn
about painting by organizing color* and
shape v about musk' by organizing
.sound in meaningful patter n*. about
dance by studying movement.

Consider the easiest one first: musk,
My nephew recently showed me a music
program for the Color Computer, I he
screen shows the music staffs, and by
movement nf the Cursor and command
keys, no to aic placed on I lie *iaff It
seems lo make sense that students
would learn about music by writing it
and listening lo their compos lUona
being played. The teacher could intro-
duce such concepts as chords and
harmony by showing students how to
improve the! j own music. The students
have a stake m their creations. Music
by other people becomes more "real**
to one who has written music.

It is difficult to convince a band to
pLi> i p.ccc of music written b\ U
elementary student- Especially when
there may he 10 such students,, each
wanting to hear their own creation LOO
times. It is not so difficult, on the other
hand, to convince the Color Computer
to play a musical com position written
by a student. It is easy for the student

lo make changes in the music stored
in h Culor Computer and hear the
results, h is ha id fur a student to change
a few notes in a piece of music and
expect a "live" band to immediately
play again the altered piece. Thus, this
piece of software seems to be an ideal
teaching tool.

The initial barriers keeping the
leaclici away from the student are more
easily overcome. The ttodenl learns
about music by actively engaging in the
process of organizing sound. It seems
reasonable that such an approach
would increase the motivation to learn
hnw io play an instrument.

How aboui os her arts? The computer
can be used to help the student learn
aboul painting as well as music Thr
l_ olor Computer has some wonderful
graphics packages. Students can first
create, then print their masterpiece on
paper lo be displayed on the refrigerator
door.

Beginning students make simple
mistakes thai can ruin an art project.
With a graphics package, it is easy lo
correct these little problems before the
Una! product is ready. This makes the
fin. 1 1 pruduct easier to accept, as well
as giving tlie \Uulcnl a valuable lesson
that art is a dynamic, changing expres-
sion rather than a "first rime only"
event

In kindergarten classes, a prc-nrt
activity Is to learn colors and shapes.
The Color Computer is an ideal
machine for lumputer.a&siiued instruc-
tion with kindergarten students. It is
easy to imagine a student running a
program which draws a triangle on the
screen while tbc cassette recorder is
talking about mangles. The triangle is
colored red while the cassette provides
a verbal e* pi arm lion of the color red,
As with all compuier -as*! hied instruc-
tion packages, a major advantage ittliat
the sludent can participate in the lesson

u.H many times, as needed.

Now, I do not know U such a program
is already on the market. 1 doubt that
it would require a master programmer
to put together a unit on colors and
slmpes. If yuu have written one, please
let me know about il and I will vluue
that information through these pages

So far, we have presented examples
of computer assisted art lessons lor
primary students. The same graphics
packages mentioned could be used as
a supplement h I activity In a drafting
class in a high school The >| ndcnl could
design the initial drafting project using
a commercial graphics package, then
complete the paper version based on
changes and corrections made to the
electronic rough sketch. Dance students
in high school could use the screen as
a model of a stage for choreographing
movement, then translate the menial
image to physical move merit.

There is probably no end to the
opportunities offered students with this
bjend of the computer and the arts.
Refute leaving this idea, a pratieal point
should be raised. The at Is ate a very
important part of education and one
of the key subject matter areas for
students to learn about our cultural
heritage. Yet, when budget crunches
happen in schools,, the arts often suffer
The must The use of computers can help
continue tlm uncial part of education
while still allowing for budget
reductions,

I must mention one of the most
creative arts, computer programming.
Just think, by your knowledge and skill,

work of beauty. Your programs can hr

wanted to experiment with animation.
Being an avid "Bug* Bunny 1 * fan, lVe
nflrn said i«i myself. "Hey! I'd lilt* to make
cartoons, too/' Now with the help of my f ulm
Computer and this program. I can create
animation lor games, graphics demonstrations
or just for fun.

The first problem confronted in designing this
program was space, I wanted the pictures for

(Way a? Thumr works as a programmer/
operator af AhpuA Ctirpurutinn, a division
0/ North American Phillips* He did hit first
programming on the Color Computer,
Wayne lives in Trappc, on the Eastern Share
of Maryland.)

By Wayne Thume

Mm ciiii ruMiitm to be held in the computers
memory and not on tape or disk. Since storing
loo many pictures would lake up an incredible
□mount of space, 1 decided to ledutx each
picture to a I6-by-32 grid.

Now before you quit reading this article in
di*gusi T let roe assure you there is more than
enough room for significant nigh resolution
animation. Using itm grid 96 pictures can be
created, which will allow for about 20 seconds
of animation. Ill be the first to admit thai 20
seconds doesn't sound like very long, bul after
drawing % pictures you will be convinced that
il is far too long.

The (tent problem was which language to write
the program in, I chose BASIC »o anyone could
easily interpret and modify the pr rig rani to suit
his or her own tastes. Using GET and PUT, I
was able to store and retrieve pictures at the
high rate of speed that is needed to show the
uiumation. The pictures are stored on pages five
through cjghi of ihe graphics memory. They are
d i splayed on lb e Hi-R c-s sk rce n Pn DOE 4 « 1 which
uses the first four pages of graphics memory.

ECU

Using shis small amount ol memory allowv for
enough room 10 create a program to utilise the
graphics for some different programming
applications.

Alter program is typed in and run T there
will be a menu which allows you 10 either
1) create a picture, I) nee l hp animation,
J) save animation. 4) load animation or 5) qtiii
the program C hoosing the first option will take
you to the Hi-Res screen pmdde 4,1 where there
is a Hashing rectangle, The size of the rectangle
represent* I nr. ii/c of the area you may animate.
The rectangle may he moved to any area of
the screen with a joystick. Once you have chosen
the area 10 animate, press the joystick fireboiton
and the area within the Hashing rectangle will
be enlarged and placed on the Lo Rca screcm
You have several commands 10 create the picture
iit i his pmnl (llimr are all summarized in a chart
at the end of ink article). Once your picture
is finished, it Will be stored and you will again
return to the menu.

The second option in the menu will display
the animation that has been created. II you
choose this option, the computer will switch to
the Hi-Re* mode and the Tint picture in the
animation sequence will be shown. To start the
animation, press the space bar. Vou may stop
the animation at any point by pressing any key
other than the space bar, I o resume animation*
press the space bar again. To quit the display
MHjLirnce before it ha* ended, press *Q" and the
liingidiii will return to ihe menu.

Option three will ivave ihe picture sequence
on cassette tape or disk drive. If you choose
this option* you will 30c what appc<us to lie
garbage forming at the top of the screen. This
"garbage" is actually the screen locations tor
nil $6 pictures that have been poked into the
video memory . The program stores all of the
information in two files, one fur the screen
locations of the pictures and nnr for ihf pictures;
themselves. Unce you have given a Hie n a rue ;ind
specified tape or disk, the computer will save
the data and return to the menu.

With the fourth option you will be asked for
the name of a file that has been previously saved.
Once thk is erne red, merely specify whether you
are using tape or disk drive Had the computer
will toad the pictures and return to the menu.

The lait option allows you to exit the
program The screen will dear and return 10
the BASIC mode.

There arc many areas of the program that
ore not explained adequately, so T have included
a sample animation program- Since an actual
cartoon would be too long to create, I had to
nick to a simple graphics demonstration, The
animation is thai of a eiide Hoveling in sine
wave moving downward. The circle is simul-
taneously passing back and foith aon\> w

vfiriud linr: in the center of the screen. It may
not be the hett example, hui it dues show how
much greater speed can be achieved! in your
BASIC programs.

When 1 he program is run, it will first display
a line and the circle, then the program will GET
the l6-by-32 area which includes the circle and
pail or the line. Next the computer clears the
screen and redraw* ihe picture with the circle
moved to the new position. Slowly, each new
position is drawn and recorded until the ciidc
reaches the bottom. The reason it takes so long
to draw this sequence is because the computer
must draw and erase each picture before it can
draw the next one.

After this sequence has been recorded the
a mm at i on wil I be d isp layer! FirsMnmr colorful
patterns ore drawn on cither side of the screen
to demonstrate that the animation can be
displayed on a screen without having to erase

any picture which may already be there. Next,
vou will sec the circle mine down the screen
— note the smooth and quick movement as the
circle glides down the screen*

And now to explain the gimmick Refer to
the graphics picture above. There is no program
included to draw thie picture, The fact is, I drew
this picture dot by dot with a graphics editor
and it would be impossible 10 create a short
program to reproduce tL When I create my
animation. I display it on the Mule movie screen
in the picture: this makes my feeble cartoons
took much more impressive.

If you would Like a copy of this screen, 1 would
be glad in send one if you send me 3 tape or
disk and enough money tu pay for postage to
send it bock. I would also like tu see any
animation you create using my program. My
address is Route 2 t Box U9> Trappe, MD
21673. □

In the tradition of good guy I bad guy conflicts . , .

Want great sound without sacri-
ficing tost graphics? Zonx
provides you with both! It
proves i hat. without a doubt, the CoCo
tan product sound without slowing the
act ion , and as an added bonus, Zonx
is fun!

To play Zonx. enter dud iuu the
program listing, if you have Extended
BASit, begin by typing pcLERfi 1. Alter
you type RUN, the program begins
reading the DflTfl s i mem em s and poking
the numbers into memory. These
numbers make up 4 Ttinrhmr language
program. After all the number* arc
poked, the basic programs will save

( f)u vhl Biften is a sttf^emptoyeed
programmer His hobby is music 1
jyntktxis. ranging ft urn his Co Co ft)
S'vncho drums.)

the 1 n j chine language program to tape.
You can Uwd I his program by typing
CLDROM and run ii by typing EXEC,
Before testing Zonx, be sure 10 save the
BASIC program that created it jus* in
case you make a typing error and it
does not work.

On ire the program is up and running
the fip.st ihiiig you see is a title screen.
At this point. Zonx a bo plays a little
heavy metal rock-aiid-iull 111m.it: while
waiting for you to press the right
joystick button.

The game begins and your joystick
mruiols bi ship that moves right or left
near the hotinrn of the screen. The ship
will not Slav trill — something to do
with gravitational photon intcrventmn.

Two different types o| characters will
fly down the screen. "Zonxes" and
"Zugs." Zonxes are the ones that flash;

Zugs arc the slugg>-lonVing things. A
Zonx will not harm you k but if you can
touch it with the very tip at your ship,
the game will have a brief "spasm" and
100 points are rewarded. Conflict with
a Zug is always futal and, since the goal
is to earn point*, I suggest avoiding
them,

You will encounter a wave of Zon*e* +
a wave of Zugs and a wave of both.
If you survive this far, bonus points arc
avoided and the level of difficulty
increases. Afler the fourth increase in
difficulty the game never get! any
harder. If you make it thai faij yuu arc
doing incredibly!

Deleter lB£a THE RAINBOW 71

Have a Httte Halloween fun with . . .

The CoCo

Hv Fred It, Seer bo
Rainbow Contributing Editor

Editor's; Note If you fane at: idea far the "Waking Well "
wltmit it in Fredcfo THE RAINBOW, Remember* keep your
Ideax spectfu:. and don*i forget that this is BASIC, All
programs result tag from your wishes are for your use but
remain the property of the author,

F

our years ago, hack when TMF RAINBOW was still
a photocopy publication of about a dozen or so
pages, t submitted my first program to Lonme Kalk
for use in hb new publishing venture. The program, Zelda %
Bat Bottle, was a simple arcade-style graphics game with
a Hail a ween theme. Bau would circle above a witch's
bulling ken It while she tried to *«p I hem into her bonle
with holla from her magic wand.

Fortunately, that game was the atari of a very ions
friendship I have enjoyed with THE KA1NB0W stall, although
our contacts are usually restricted to phone conversations
or a RAl NBOWf est encounter, Now, some four years down
the rood, ■ Wishing Weir is in full swing on a monthly
Uni^iv, find I Am Mill hawH^ ti> nmrU iu n Bfoalinfl new
program* it 1 was with ihe original Zelda game

With all this in mind, the thought occurred to me that
it might be time to create another Halloween game tor
the October issue. I toyed for a few days with the concept
of creating a game called Peter. Peter, Pumpkin Eater,

(Fred Scerbo is a special needs instructor for the North
Adams Public Schools. He holds a master's m
rduratiutt ttndhw publtxhrd xome ofth? first xuftwurr
available for the Color Computer through his
software firm. Illustrated Memory Bunk u

but no matter how hard I tried, the program kept looking
too much like Pac-Mnn or my own Snail's Revenge. Some
ideas even surfaced for Zclda (L but none seemed to catch
my fancy. Over and over again* I kept coming back to
4 lit idea uf doing something with a pumpkin, while at the
varue time not making ii something limited to ilie munch
of October only. Deadline was approaching, what could
idol

The Wfoh

1 took another look over my recent mail, A consistent
pattern was always visible: People liked games, but they
also tike programs that could teach something. Most of
ail, readers indicated that they usually got the most out
of programs they could alter, with my instructions, to
include things they would create After much thought, 1
CHtue up wiih a program thai would include all of iUis
and still fit into my plans for a special Halloween program.
The result is the Co Co Puzzle Maker t written lor 32K
bx tended Color BASIC,

1 he Program

Like a puzzle you would buy in a box or find printed
in the pages of a magazine, Co Co Puttie Maker jumbles
an image on Ihe &ctcen that the user must reassemble. To
lit I he Halloween spirit, the image I have chosen is a bright,
smiling jack-o 1 - lantern. Every time the program is run, the
puzzle will be jumbled in a ddtcrcnt way, bach square
ol the puzzle on the grid will at some point be surrounded
by a flashing square. The square may be moved around

THE H JON BOW UclDMI

When ihe flashing box surrounds a piece you wish to
move, pursi ihe enter key and the image in the box will
vanish. Use the key* to position thr square over another
section where you may want in put ihe piece selected.
Position it where you wish and press fntf.r a^ni n Thai
piece will vanish and then the two pieces will have
exchanged places,

Continue to move pieces around the screen until you
have assembled the image the way it should look. When
the purrle is rnmpleir, press the Letter 'S' and the screen
will clear and tell you how many minutes ii took to complete
the nuzzle,

Al this point you may cither press T 1 to view the pnr/le
picture without the grid lines, or press "R* to run the
program again and try Tor a better time. When you view
the completed puzzle, pressing bNTER will return to the
text menu.

Sound simple? Well, while the couoepi is simple, you
will be amazed at how tricky it is to complete the puzzle
quickly. On lirst running the program, you will notice the
screen is either red or blue. If the screen is not red, press
Reset and run again until the screen is red. When it is
icd, pies* Pirn* to start the program. (1 used this me I hod
rather than the type used in last month's column since
some of you may wish to use your own graphics for the
puzzle and this is a more consistent method to use,)

Cresting Your Own

Mere's where the beaut) 1 of Co Co Puszk Maker comes
in. I have Icfi ccuixiderablc space between the start of the
program and the actual pu/zle routines for you to draw
your own picture to use within ihr pivs?lr Those who have
Graphical!,. CoLo Max or one of the other graphical
programs available could also use graphics created with
these and mer^c them with Puzzte Maker according to
whatever instructions those programs give to merge your
graphics with programs.

Let's say you simply wish to draw graphics using
t'xtended Color BASIC commands In that case, place your
lines between tbc numbers 200 and 1999 fur the drawing
You may delete my graphics by typing DEL2lfl*r399 and
pressing t.viER. Now, enter the following lines to create
a concentric: circle puzzle:

210 CLS& : PM ODE 4 ,1 : PCL50 : SCREENS » 0
228 FOG I -I TD 180 STIPB
236 CTBCLE{12B.96)»I,l»-9
24* NCXTI

Believe it or not, the puzzle you create with these few
lines will be very challenging to solve. Even I have had

difficulty with it. so if yim try tt 1 you will see that this
program can be for almost any age level, depending on
how difficult the design is. If you really want it to be a
chalJcnpi, ehunpe Line 220 to this:

22& FDRI-l TO 208 STEP*

Thai will really make ihe puzzle tough.

If you Want to draw a simple: ih^ign, iry drawing the
image outside the program starting with Unc 210 Tn get
an idea of the area the drawing should remain within, you
may first wish lo draw a box using the i_INf_ command
with the di mmensions:

LINE13Z,3?)-(2?4 N IGRJ .PRESET. B

or

LINE: 32. 321 [224,168) ,PSCT,B

This gives you a square to draw your image within which
the shape of the puzzle will fit.

1 chose nut to use the full screen since some of you
may make drawings which would leave too much blank
space for the puzzle piece v Also, some of the available
graphics programs do not fill the whole screen because
they use a border for the colors and keyboard command*
I think you will find this size his those programs very
well, but you will have io do the experimenting; I do not
have any «>f those commercially available programs at my
disposal. Judging ft um the artwnrk that has been submitted
to the "CoCo Gallery/' 1 am sure you will come up with
some outstanding puzzle graphics. Please refer to the
instructions of your graphics program to deteimuir Inm
to merge with other basic programs.

Conclusion and * Few Mora Points

You may now wonder what is educational about this,
I firmly believe that using pozzies helps young students
with logic skills. Molding this with the rnmpuler keyboard
is only bound to help with those skills,

You will also notice the program does not tell if the
completed picture is correct. Pressing l S" only tells how
much time it look to complete, not whether or not you
got the picture done correctly. Adding that feature would
have made tbc program a hii too Jung, As it is, I regret
that 1 could -n't crunch this down into InK. hut ii may give
some of you an incentive to upgrade.

Also, be patient while the program draw* [he puzzle
picture. It may take as long as a minute, hut the program
is working Umil next month, enjoy the pumpkin puzzle.
Happy Halloween! □

A Final Session
With The f A' Option

By Joseph Kolar
Rainbow Contributing Editor

C rent i ng graphics on CoCo is bo
rewarding :md iht possibilities
so, rndlrss To prove I he point,
we are going to have one final session
using the 'A' option of DRAM. Consid-
ering that we have limited ourselves to
utilizing a single design element w©
ha\e ?otne a long way, baby! As a
beginner, you realize the door being

opened fur you hu uinmrlrss avenues
to explore. The only limitation it the
depth of your imagination.

You are urged to ask yourscll ques-
tions while proceeding through this
tutorial. Make a note of them and later
pursue these byways; you never know
where they will lead. Rest assured you
wilt have learned .something.

Turn on your b&st friend. CoCo. and
from Listing 1 key in lines 0 through
40 and 500. AS and CS design units
are the same ones you used previously.
Perhaps we are in a rut, however, these
muis air ideal tu demonstrate fhe&cope
of the *A" nptinn

Our project for today is to create a
display using the eight possible orien-
tations, radiating from a single, central

fJuyupii Kuiut n a /ree-iiitite mittt and
programmer dedicated to proselytizing
for computers m general, and the CoLo
spcctfit&Hy*)

point (LHUERFDfi). They will be
displayed one ai a time and then erased.
We will put them in an endless loop
and HI tempi (ogive the display m feeling
of motion.

Line 40 creates the horizontal design,
AS, rudiiiTing to the Iclt Irom a central
point, Note that you coutd have started
in some other quadrant (orientation) of
AS. (You may want to explore this on
ymir own.)

After you key in a line, RUN and study
it; BREAK unless otherwise directed,
Vou will get the maximum benefit by
progressing slowly through this
tutorial.

Key in Line 50, CoCo did not require
any new or additional information, so
il added C% hi the disj»la> Ktiy in Line
60, The only new information CoCo
needed to know was the new orienta-
tion, "AL" Hey in Line 70, It is similar
to Line 50. serving the same purpose,

LIST and look over what you have
worked up. Without inferring to Listing
I T create and key in the foot rlcMgu units
needed to display all eight orient alionv
They will be designated as lines SO. 90.
100 and 1 10,

Note that the diagonal units begin
at the central starting location, We
prefer Eo back off three units from the
central point to give the entire diNpluv
a twist to the right. In Line 20, insert
alter the opening quotation mark ("),

BL3. In Line 30. insert BK3. Now the
design elements appear to rotate Like
a whirligig,

Frankly, backing off three units from
the central point is a time^onsu ruing
project and must be given as infnrmji-
lion changes to CoCo m lines 40-1 10,
You may want to work it out on your
own. 11 you want to puzzle it out land
it is worth doing), after deleting BL3
from t ine 20 and BH3 from Line 30,
make a csfwe "PUZZLE" and set it aside

to work on later.

Our next step ia to remove each item,
one at a time, in the same order that
we displayed them. Key in Line 120,
We used CO to inform CoCo of our
wish to blank out AO of AS- In the two-
rolor PM0DC4 T use either CO, C2 ur C4
to blank nut I be dcaign. Try them all
and see! You may prefer to use only
the CO .

Vou must have figured what Line 1 JO
should read to erase the first diagonal
— key it in I Then key in the reit of
1 1 1 r- linrv I4Q tjffOUgh NiV Yuh will
notice £hr display was completed and
then erased. Tn recycle it to continue
indefinitely, key in Line 200. The only
trouble is that nothing happens! Why*.'
Notice that in Line AO no 'C color
ption is given. CoCo knew it was CI
oecause, without instructions, it knew
that it is the color you desired, H is
the default option, CoCo is given a

color change in Line 120. CO, When
it recycled buck to Line 40. the Lost
information regarding color thai (JoL'o
had was CO. it assumed there was no
change and you see the net result.
Nothing'

The solution is to edit Line 40, ima I
CI, or if you prefer. CJ, right oiler the
opening quotation mark ("J, Now CoCo
knows for sure that every time it reaches
Line 40, Cl is demanded r

compare new results with previous
ones; it is u good way to Learn. The
newcomer gels to know what to expect
when he does thi& or that. Ask yourself
if I do this, it looks like this. If 1 do
ihHl, it luuks like that, What is the
difference? Wlmi didl ihtrnge? How did
it affect the display? Is i his imponmii
information t want 10 squirrel away? M
That is what the keys are lor! Tickle
theml CoCo won't Ret mad\

Lion. The more diagonals* the more
distortion, i he rule is play it safe. Use
sizes beginning with S4 and increment
upwards to larger sizes by +4.

Make lines 15, 700 and 710 Rfcfl lines
by inserting an npustrophy (*) at the
bc^muiug of each line Ruck to the
drawing board!

Add to Line 40 + W SI0 , *+AS+ ,, S8*\
The S10 increases the size and AS prints
this larger design element over the
smaller one, 5g maintains the sue of
(he diagonal element, CS t in the
following line wifhoui di*r orbing it

80 and I IX). In order to make the
blanking lines, 120, 140, 160 and JKO.
erase these additional design units and
add +' 4 SI0"+AS+"38" to them.

The design is off-center due to the
insinuation of the I a > get aiie. Adjust
this by changing the BM 128,96 part of
the instructions to CoCo in Line 44) to
BM 138,106, The design is swept oil the
screen very nicely, but the placing of
the units 1$ Jerky; adjust Line 600, Use
a value of nbuin 30 or 40 to get a rapid,
yet smooth rotation.

Just Lo sec what happens, icimrvc the
BL3 from Line 20 and RflJ from Line
30, it's OK but it must be recent ered
by changing the BM values In Line 40
to the original BM 12B.96.

Tin i Id we add four 54-sized units to
the AS r.1e.menls* Change the S3 at the
end of the Line 40 to ^S4" and arid
+AS+-SIT. This adds a small unit to
the firs; horizontal onentauon. Make
the same changes in the other three
one at at [ons ai line? 60, SO and 100.
Tliat looks good enough. The S4 units
add interest to I he di spiny as it is
created. Not erasing it enhance*
grand design.

Just m case it looks better blanked
out, modify lines 120, 140, 160 and 180
by changing SK to 54 and adding
+AS+"S&" Check it out! If you like this
result, C5AVE it If ynu prefer I he other,
readjust lines 120, 140, 160 and 1 80 ami
CSflYT.. Kc member lo adjust the pause
in Line MX) to some value that pleases
you,

Out of curiosity, in lines 120, HO,
1 60 Hiid I SO change S 10 to and delete
the rest of the line. This is just another
variation that erases only i he S8 nn bulh
the AS and CS clement*. CO AVE. if you
desire ►

You could Wi up the diagonals by
adding to Line 50 +"54*'+C$+"Sr , 1 ete.
Or try this: Change the last AS in lines
40 r 60, 80 and 100 lo CS, There is no
end to what you can i/rvetiigaie

* f The point is that a beginner should
always try different valaes> Take time out
to do so* Every try allows you to compare
new results with previous ones$ it is a good
way to learnt*

When in doubt, it is best to put ;dj
the required option information that
CoCo may require, such a* *S' for size
and "C for color, and since we arc
working with *A*. *A* for angle orien-
tal ion, Even if it is redundant, it won't
detract from or affect the resultant
display. As We progress, you will Omit
Ihc citiuiieous instructions to CoCo.

Wr hsive r rapidly revolting whirl-
igig. Suppose we wanted to slow it
down. We could try putting pauses
between each element displayed, hirst,
let us try slowing down the part that
dmws the elements. Add Line 45: 4a
for t-\ To zga: next then hum and
press BREAK. You should put un a few
more to get a better view. Key in lines
55. 65 and 75 to read the same as Line
45.

That is not too bad! Since we are
going to require many pause lines, we
might k> well create a G05UB routine
Hey in 6®e FDR ? = l Tn ?9idt NEXT:
RETURN. Re-key Line 45 to read 45
G0EUB Gee, If it is OK, rc-Sicy Lines 55,
65 and 75 Key in required lines 85, 95,
105 and 1 15 fall GGSUB E«(J>.

h looks neat I You might like to
change the value in Line 600 (200) to
sec if a longer or shone i pause appears
to be more effective. Using a value nf
300 provides more time to study the
dUpla> as the elements arc augmented.
A value of 100 or less (lo about 30)
gives a better sense of speed, tt is up
tn you |o chouse a value. For the
purposes of the tutorial. 200 will be
used,

The point is that a beginner should
always, try different values, 1 akc lime
out to da so. Every try allows you to

AU these GQSUS tines could have been
tacked on to the DfiRw lines, separated
by colons (:), to make multiple line
Maienieniv When you are in a mad
frenzy of creativity, make separate- linr>
Why? It is easier to follow the listing
and you may decide to odd additional
items to the UWHW lines.

tt is easier to edit short program lines.
Also, errors are easier to spot* There
is plenty of lime when I he program is
finalized to make it more elegant by
tightening it up: removing unnecessary
or redundant program lines and,' or
making multiple-line statements.

There is no sense m putting G0SUB
routines between the erased units in
lines 1 20- 1 90 Mir in \ i-MVi-i u» < m kJ In-
additional pauses that would cumula-
tively become one long, additional
pause. Who wants to Look at a blank
screen?

Suppose we added four AS units, size
S4, to give the displav more body? Add
+"S4 in +AS to lines 40. 60 T SO and 100.
Uh oil! Befotc wc gu any Luther, lei\
change the size to SI2 and RUN. Li is
too large! Let s try S10.

Note: Usually only S4, SB. S12 and
S16 will work properly when diagonal
lines H. E, F and G are used lo create
a design Thr figures will become
distorted, Co incidentally, the designs
we Created. AS and CS. have propor-
tional Lines tn even number of units.
2, 4, 6 and 8, and the geometrical
relationship did not suffer,

Let's take time out to illustrate this
point. Copy from Listing I lines 15, 700
and 7 10 but omit the REM marker*, After
running, try in succession S 13 to Sift
You Will get varied degrees of distor-

You arc encouraged in dream up
things to add> remove or change. Take
tunc out to try them all. Make this
tutorial a springboard to further
experimentation, if you play around +
your endeavor* may suggest unex-
peaed avenues to explore.

Mentally* question everything you
key in. Never be afraid to alter a
pmgnim. You sliuulU ttlw^i strive to
modify a program, giving il yuuf
personal imprimatur. Create your own
designs on graph paper and even
substitute them for the designs m hues

20 odd 30, You will be fascinated at
the startling designs you create. Are you
still sure you're a beginner?

Let me leave you with a challenge.

ment in htm. It wou*l pruve anything

SOUND SYNTHESIS

Disk

* a 1

By Stephen Gunn

After seeing Jeremy Spillcr's
'Analog-to-Digital And Back
Again* article (June I9B5, Page
3ft), I jusi had 10 iry ill I typed if in
and it worked; ihe only problem was
I hat it would only give about 13 seconds
ot sound. The program only used 32K.
so 1 modi fled it Tor 64 K.

The assembly language listing as
rather shorty so it has been modified.
Also incl nded tin? four r on lines for
moving blocks of ujcmoiy Cm mm ilii-
upper page of RAM into the lower page
and bock again* there) ore the BASIC
SflVEM and LDftDN commands can be
uted,

Hiiw the Nr-w Frogmen Works

The &A.S1C program no tnnge( pukes
the routine into memory, but loads tt
from disk (or cassette}. Ibis makes
changing the assembly language routine
easier. The uaSIC program then sets a
flag in RAM, so even if you press
rrfax and | lien Q) IW I he program again,
it won"! bo ihe i reloading the machine
language routine The BASIC program

(Stephen Gunn has had his computer
fat ihret? i rar\. Hr plans jo en wr college
i his fall mid major in rompuirr \tirtur J

also turns off the interrupts which
allows for better sound quality.

You are presented with a menu
similar to the old version's. Selection
oue is iht same as in the original
program. Select mo iwu i^, iliffrrenl in
that you can now also control the speed
at which the tape is read in. Selecting
a speed o! one will give a higher
sampling rate, hence better sound but
less playing time (about IS seconds.).
Selecting 1 5 as ihe speed will give much
lower sound quality, hm I lie- playback
time is 75 seconds, five times longer
than the original program,

(One note: If you want something to
sound the tame when it plays back,
select the same speed of playback as
when it is read in. For example, if you
read something in ai Iht: speed of 11 T
to have it sound the same il most play
back at the speed of 1 1,)

Selection three is playback, same as
in the original version. Selection four
lets you save what is in memory to disk,
btil be warned I hat a disk will hold only
two complete dumps from memory,
The filename has to be seven character*
or less because the program saves
memory out in three files, adding the
numbers '( ; T and \T to the luename
given. After you save memory out, what

is in memory is more ni less destroyed
by the saving process, so tn listen in
the same file use Selection five to reload
it. {Selection five loads files back into
memory,)

The modifications were created for
a disk system, but I see no reason why
they shouldn't work for cassette if you
change all of the LOAD Ms to CI nflrVl*
mid oil of the SflVrjM* to CSAVDls.

Loading Instructions

First, using a.n editor /assembler, type
rn anil Assemble the ML program. If
you bdvc d disk system and are using
the cartridge EDTASM, assemble it to
tape, then reconnect the disk controller
and transfer it to disk, If you arc using
disk BDTASM, just assemble it to disk.
Make sure you use the filename
SOUND:

If you have lite old BASIC version of
Jeremy's program* you can just add my
routines and changes to his program,
otherwise you will have to type m the
whole program (it isn't too long),

1 enjoyed modifying AID DRV it for
64K, and 1 hope you will enjoy using
it* If you should have any questions
regarding this new version, you may
co ntact mc at 944 Wisconsin, Oak Paik,
IL603U4, Please include an SASL. O

Guess My Number — A Mary board

Here is a "Guess My Number" game we play with very
young children using paper and pencil. First, we write down
ihe numbers from one to nine.

1234567B9

Then, we secretly pick u number. Lcfs pick seven. The
child guesses. Suppose she guesses three, Wc put a ^pointer"
above her guess.

1214 5 6789

I tic pointer f» points toward our secret number. Of
course, it also means "greater than. " So we say. "My number
is greater than three."

Nuw suppose she guesses nine. We put a '"less than"
profiler above Hr,

By Jim Ktfnl

I've been a rainbow reader for years. The
first high resolution machine language
girij.ihic* piugiriiii 1 ever winked wax Dennis
Lewaudowski's shoot- 'em- up space game in the-
November J 982 "Assembly Corner." Since then,
I've bean plugging away at my little CoCo and
no w have a program of my own t o of fer Digital
A quanum.

A "digital aquarium 7 ' is no substitute tor a
real aquarium, it docsrfi make gurgling noises
(though there are bubbles) and the fish won't
recognize you or flare their fin* M a mirrur. Slill,
there are no water fillers lo etc an and, if one
tires of a Hub, one can simply remove it from
the object List with no twinges of conscience. It
is also a good example of what your CoCo can
do when you ask it to. There arc over 50 objects
being moved at once* (I'd like to sec that on
a Commodore! 1 )

(Jim Kent is a programmer at Island Graphics. He
studied math at UC in Soma Crui, Calif, }

Uctc.ce r lBBi THE RAINBOW 107

ll would really be besi to get RAIN-
SOW ON TAPF in enjoy this article. IVc
included a listing of the assembly
language sou ret, Those who don't
already know can sec that machine
language programs lend to be very long
if they intend to do much. I his is
because each line in assembly code does
only something very simple. The basic
liner

i- j + k

if anslaT.es 101

Ida j
adda k
st a i

Similarly, a basic line of any com-
plexity \% apt let lorn into a CoCu
screen-full of assembly language
Unless yon are trying to learn assembly
language, typing in Ibis program will
probably be impossible* Cor a single
typing error will be enough to make
everything it 01 work. It U 3 pretty
program, and T hope people no4 trying
to learn assembly language will he able
to enjoy it as wcIL

For those who have done some
graphics programming. Digital Aqua-
rium derives its remarkable speed and
MTiuuthncis through the use of p ra-
sh [fled shapes, a OR^u-riRAui architec-
ture, as well as from being wrilferi in
fairly tightly-coded 6809 assembler.
Anyone wishing to incorporate parts of
this code into any of their programs,
even commercial ones, should feel tree
lu do so. 1 hope it encourages soma
games chat don'i Involve missiles in
space or jungle munch-'em-ups.
only regret with Digital Aquarium is
that it docsnt use joysticks — yet.

There are two listings that accom-
pany this article. Listing L, written
to be assembled using The Micro
Wurks" Macru-80C, is the machine
language code that actually docs the
work of animating the fish and also
contains the code to produce a small
aquarium. Listing 2, WW, is a BASIC
program thai uses the Digital Aquar-
ium as a use [ } routine , The aquar-
ium will run until a key is pressed, then
it will return to HASir The PCI 5 [ 3
call can be followed by other RAsrr
graphics commands it a more elaborate,
non -moving background is desired.
(The October 1985 RAINBOW ON TAPE
includes a longer version of the machine
language program, called F LARGE, as
well. To use this program, ju>t change

Line 20 of Listing 2 to LOADti
^FLflRGE*.

1 have tried to document the assembly
language as much as possible. 1 did not
have the luxury of an 80*column screen
when T developed this program! SO
con 1 incuts appear tin the line after the
code they refer to rather than hi The
end oj the same line. All parameters
are passed to subroutines in registers.
Subroutines are required to save
registers ihey use unless those registers
return values. The one exception to this
is the software hi iitcr (rectangle mover)
routine named XORBLIT.

1 he only truly hairy routine in ihis
package is CLPBLT or "clip bit*.*
Personally, I am just happy ft works

and that 1 no longer have to understand
exactly how, This is a vital routine,
however, If n weren't for CLPBLT. the
fish that are half on screen would also
hr hair nn ihr rode, and believe me,
tins in place of RTSs lead quickly to
seaweed soup!

Most ot the machine cede is set up
lt> interpret the animation list, which
is declared at the bottom of Listing I
and Listing 2. Members of the am ma*

ti4.nl list me characters, which are
themselves composed of three parts:
position, path and image. In each frame
three t unctions are called for each
character. First, a function associated
with the path of the character is called
and update* the position, then a
function associated with the image is
called and stuffs Register X with a
"raster" (a recta ngutai array of pixels
little square dots), and Registers A
and B with ihe dimensions of the raster,
Next a function to draw the raster at
the character position is called. The fun
pari of this set up is that different images
can have the same path and vire-vrr*a
Furthermore, new types of paths and
new types of images can easily be added.

Currently there are four types of
paths; STRAIT, BOUNCE, YBOUNC
and SAMPLED. The STRAIT and
BOUNCE paths require only two

numbers to define in addition to a "type
byte" at the begin mug. These are
naturally the horizontal and vertical
offsets to be added to the character
position in each frame.

The SAMPLED path is a bit more
complex. The formal is a type byte
I'm Mo wed by two bytes to say how many
samples there are, tw» bytes to say
which sample we're on now, and then
a List of the samples themselves. The
samples are really offsets just like the
straight type path. The difference is that
you move each frame on to the next
offset rattier (ban always using the same
one.

To go with the four types of pal lis
there are three types of images. The first

of these is STILL. A STILL contains
the type byte stating it is a STILL,
followed by the dimensions of the raster
containing the image, followed by the
r alter itself. STILL shapes will jerk if
moved horizon tally, but require only
one-fourth the memory uf the other
types of shapes.

The second type of image is GLIDE
As you may know, in the color Hi- Res
screen modes of your C0C0 a single
pixel takes up two bits, This means
there are four pixels in a byte. The
CoCo Is a byte-oriented machine ; it is
not especially good at si lifting around
bits within a byte — it will do it. but
not nearly as fast as it will throw around
bytes whose bits it doesnt have to
twiddle.

The upshot of this is that if you want
Mrnuuli movement in the horizontal
direction, you must have four copies
of an image, one for each pixel that
lives in a byte, This way, when you want
the first pixel of an image to go to a
place on the screen that is itself, say,
the third pixel of a byte, you do not
spend ages shifting the whule image a
bit ai a time before making rhc copy,
but rather simply decide which one (in
this case the third) of lour pre-$hifted
images to put as a byte array onto the
screen.

"The upghot of this h that if ynu want * month
movement in the horizontal direction, you
must hare four eo pies of art image* arte foi
eaeh pixel that lives in a byte J*

108 T MC RAINBOW Odninn <Hfl"i

Therefore, when an image is declared
lo he type GLIDE you supply the first
raster just as if it were a STILL, but
then you reserve space for three more
copies of I he Image — pie-shifled
copies, for the machine in fill in nnce
>t gets going,

The type WIGGLE is wry much like
GLIDE, except instead of the Co Co
doing the pre- shifting you do it yourself.
The ad vantage of this U that without
using ritij mi'nf mcmurj C tin n tl would

take for smooth motion, you can have
a shape that wiggles a little as it moves
horizontally.

If you don't have KAINBW ON TAP£ T
for a copy of the program on disk (So
and til supply disk), fresh shapes to
animate or perhaps to engage in a
digital fish exchange, contact me al
I0OI-A O Reillv. San Francisco. CA
95129. As it stands, the program only
works on machines with Extended
Color Dbt BASIC, To get it to run on

a cassette-bated system add the line: 25
POKE 3 BAG, 8 to Listing 2 This Wits
it your screen is stalling <il $800 ins lead
ot SLQU. It should run on |6K machina
with no problem.

The Digit ai Aquarium wa& written
using a Mktu Works Macro-8DC
assembler and editor wiih local labels.
(That's what alt the A®** are, fnlki )
If you own a less intelligent assembler,
I'm afraid youll have to make up new
labels for them* □

READING "RITIW AND RAM

Computer literacy is being touted as the
fitui ill 'R* in ethical ion circles these

unfamiliar with the possibilities of
computers as learning tool*, but con-
cerned with their children's education
— wondering what to do.

The New American Library has just
published a book, Ctimptikids: A
Parent's Guide to Computer x attd
Learning, that is designed to provide
parents with all the information they
need to know about their child's
computer education.

Written by Felicia Antonelli Holton,
Ctimpukidi seeks tu explain computers
and how they are used: al different age
and grade levels; in teaching aubjec it,
like art* music, math and grammar; in
homework; and in the education ol
children with handicaps or learning
disabilities. The book also tries to help
pH rents assess ihe quality of computer
education ilieii diililirn are leceivmg

An Adventure
Into Sound
Experimentation

By Bill Bernico

A demonstration on sound production with the
SOUND, PLA Y and EXEC commands

One of the things a lot of programs overlook is also one of the
things the CoCo is very good at . , . producing sounds. With
the help of SOUND, PLAY and even EXEC commands, you can
produce some very impressive sounds to help showcase your programs
and make them more interesting.
The SOUND statement is the simplest. A com bi nation of SOUND

I SI J i^nilND ??fl,7:5mNn IB, 5. for eif ample h wilt
produce three separate notes. A shorter, easier way
is to use the PLAY command. With U T simply tell the
computer to PLAY "CFG* and you will also get three
separate notes.

As for EXEC, 1 had to experiment with different
combinations to come up with a sound. For example,
in lines 530 and 550, 1 used it to create the "helicopter*'
and "rasp berry 11 sounds. EXEC 43345 hy itself will
piuducc a shoil "click* 1 ui "blip" sound. Enclose it
in a loop, as in Line 550, and you will get the raspberry
sound,

Id Line 530 youll probably wonder why there Is
a CIRCLE command when there are no graphics.
CIRCLE is there only to create a delay between EXEC*
so there wont be one continuous sound, rather a
broken sound such as a helicopter taking off. You
can substitute a short FOR^NEXT loop if you dout
have F Mended BASIC.

Running the Program

Sound Story could have simply been a menu with
different sounds ;<■> pick from, but careful aim lysis
tcvealed that the attention span of the program would
be about 83 seconds. With that in mind. I decided
to integrate these sounds into a short (and 1 do mean
short) Adventure.

( B\U Bernico is a self-taught computcrist who enjoys
programming, golf, TV and music. He has played
with a Ws rock band for IB years.)

The memory for a page is used for
storing each function you use to draw
the schematic. If you start running out
of memory spacr, the computer will
warn yuu hy beeping.

The main portion of the screen is
taken up by the schematic work area.
The sides at the work area have grid
marks on them to ease ih« drawing of
lines between pages. The work area
itself Is stippled with dots every eight
pi*el». When you arc in the schematic
work area, your cursor will "Snap" to
cither the dots or to the area halfway
between the dots* This makes the
positioning of line end points, compo-
nents and text easier,

OK. u quick review: To select a
function from the menu, move (he
arrow cursor to the function and cl*k r
then move down into I he schematic
work area; to exit a (unction move the
cursor hack into the main menu. Easy,
isul it?

The next menu selection is the box
function. Well include in our discussion
of the box function (he fourth menu
item (dashed box) and the fifth menu
item {erase), as these functions arc very
similar.

Select the box function and move the
mouse w the point cursor is in the
schematic work area Move the cursor
lo a point where you want oni* corner

point cursor back again so youll be all
<cl la draw another box.

The du>hed Ihia inn] cnisr Amnions
work much in the same way The
differences ate that with the dashed
box, when the box has been defined,
A dashed box will be drawn. With the
erase, the area En the box defined will

grammed components from the com-
ponent library, Get the arrow cursor
hack and go op and select [he c-ompo

the bottom of the menu on the left are
the words "PREV and "NEXT."

and be replaced with a new one.

The first item in this new menu is

A Rumor Behind Its Time

• A/v question is about a rumor I
heard about the new Disk SASic Li
ROM coming out: if this is true or if

fFJ FJlers. a RAtsmw and PCM Kit iff
member, is a self-confessed electronics
fanatic whose other interests include
.science fiction.)

it already came out, what does it have
niter Dhk S4StC t.G?

Rkk Cadutrttr
Btddeford, Maine

Disk BASIC 1.1 has been around since
late 1983. The only advantage it hat
k a DOS command for booting OS-
Q Matty r.ii" i Ik; routines in 1. 1 have been
moved from their I ft location*, ami
quite a few programs that used them
directly did not work with 1.1. For this

reason I recommend sticking with 1.0.

Is It Extended, or Something Rise?

* / am 9 years old and just love to
play with Dad's CoCo. When the new
ft A how comes, I grab it and type in
the '"One-Liner Contest " listings from
tt, Sometimes they will not Jit in. and
my dad docs something called "edit"
and then they will Dad says his
computer is Extended and wry long
"packed" line* cannot bp put into a
standard computer, fan thi\ he mj ?

What do all the people without
Extended do?

Sataiha Swainc
Hantsport. Nova Scotia

ThMi tried (using i lie EDIT mode tu
squeeze a few extra characters in) li

quite common In our "One-Liners."
Your father i& right in that EDIT is an
Fx tended hamc command and isn\
avail ahlc on the "mttdaid " trnxlcls I
suspect, though, that a program that's
been packed in this way is likely to have
been written for Extended BASIC
anyway. At any rate, those without
Extended Color SAStC can always
divide I lie One-Liner into i*o si h oner
lines in nrder to use them.

Reversed in Some Respects

• / decided w try a hardware project
in your April IQ&5 issue, the video
reverxer modification P*Turtt Vttur
Monitor inside Out." Page 116). The
project is relatively simple and ajter
completing, u, it worked fine, except
n hen I went to the edit mode of
Telewriter-64. 77r* scretn was again
white with Mack lettering My quest inn
is, Lx i his normal, and if ah. why?

Bill Spiltaiw

Phoenix, AZ

The video rewerser project simply
forces the 6847 video chip, when it's
in text mode, to me the green-on-black

154 THEHAOieOW Oi-rmr** lQfli

characters instead of black -on-green.
Telewriter \ edh mode uses the PfltJDE
4 Hi-ftc* screen, which is unaffected

horbidden Variables

• When i have attempted to use the
*trtng vatiuhlr designated us Fhf$> \ get
an error message. Why?

Marc A. Sehenider, Psy.D*
Evanston, JL

Some of Microsoft's several hasics
designed for various computers (includ-
ing i he CnOA BASIC) arc vci up so you
can't use variable names that arc the
same as commands or I unctions. In this
cose, tMcndcd command DEF FN
predudes I he use of FN as a variable
name. Later basils like the BAfciti on
I he IBM PC, let you Jo I hi*, but ihesr
al&n wake ymi ly|ie * spate hciwceu
a command word and the rest of the
command (such as FOR N = I TO 1®,
instead of FrjRN^lTQia),

Umrmsint* thai WniiH Stmrt

* in the January I 9B4 RA WSQW, Page
48. there is a disk utility far transferring
programs from tape io disk, At the time
I didn't haw a disk system, so it has
sat in my raw bow o.\ lAPt cosmic

and have need to use the program, only
to find that it won't work. What

five columns in the upper left corner

t\j the >t rrrrt r arid the cassette player
motor starts. Tftt computer is locked

I have wondered ij there is an error
in the program. I have not been able
to locate the February or March 1984
issues to see if there Is an errata. Could
y<tu please check for me?

Modern Mailers

• What happens in the modem signal
when it enters the serial ffOprtft? How
is it processed^ and in which memory
locations? I am thinkinx of making a
communications program, I want to
know how the other programs access
ihe serial I/O port, and how they
translate all of those beeps into char-
acters and characterx into hveps.

Robert Bavvi
Winnipeg, Manitoba

F\rM it f nil, the "beeps'* are handled
in the modem, which takes DC vgnulv
Irom the computer and Uanslalc* lite in
into tones while translating the tones
from the other end into DC signals for
the computer. [\n RS 212 interfaces a
'V is represented by a positive voltage
tif i in cp vulit or more; a '0* is repre-
sented by a nrgalivr voltage, not by *ero
voltage as in a computer's own logic
circuitry.)

The CoCo handles serial J/O using
an inexpensive method ihat, unfortu-
nately, makes terminal programs more
complex. The serial input and output
signals (shifted to the standard **TTL"
levels) arc connected to twn inpui .un\
output lines on the second PI A ( Parallel
Interface Adapter) chip. Input is ted to
input bit fj of Port B "at address FF22
Hex); output comes from output bit I
uf Pun A fat FF20 Hex). This means
the microprncrtstu ihetf has to take
care of the Daud rate, number of tttri
and 3l op bits and such. Dade is land-
ably. Ibis makes senal i s O on the CoCo
somewhat unreliable and slow, espe-
cially when both sending and receiving
are invoked

Many other computers use a circuit
called a "Universal. AvynchroiKius
Keccivcr/ Transmitter" (UART for
short), which can ttt programmed ">■
take care of the Baud rate and number
of bits automatically. The processor
I ken sends the data to be sent out to
the 11 ART in parallel form and the
UART sends it out serin Ely. while also
taking incoming serial data and con-
verting it to parallel io send to Ihe
processor, landy's Deluxe KS-232
Program Pak and some other packs
provide UART-based RS-232 ports for
the PuTo, which make modem and
other operations more reliable atid
taster as well as freeing up the CoCoS
senal port for printer hookup.

Using association to team the parts of the heart

A LESSON STRAIGHT

FROM THE
HEART

By Denis Santerre

The CoCo is a wonderful machine for learning.
It is an asset when assnriaiion is helpful. In
Ihe September 19R4 issue of 1Kb kajNBqW,
Joseph S. Paravaii showed Ul how association can
he usrrJ rn Irani the states and capitals ("GeoGraphics, 1 "
Page 177), From his program J got my character data,
wHich he had gotten from TRS tiQ tfewj, April I982 t
by R. Van Dyke.

Heart Quiz is a program that uses association lo
learn the parts of the heart. Before you load the
program, type POKE 23fl4B,fl s poke 25,3$ and enter,
then type new and fntfil Tliis will clear the memory
for 12 pages of graphic* instead of the usual eight.
If you do the poke after you load in the program,
ii will be gone, so be sure to save it as soon as it
i> typed in.

When you run the program the computer will draw
the heart in two locations in memory. These iwo
drawings are a little different one is the outside of
the heart and the other \\ the in vide chambers, For
each part, the program will sdeel one of these two
drawings; it then will copy the selected drawing, To
this drawing it will add the needed graphics for the
pari llutl is lo be identified, By switching pages hacV
and forth, this added graphics will give a flushing
image until a kev is hit.

(D$nh Santerre is a hj&mcdicctf equipment wrhnicinn m
Eastern Maine Medicai Center He is a setf-taught computer
hubhyisl.}

OraOQvrlW^ THE BAM BOW 163

As an aid to Hir durv I he Length of
words is given with dashes. Spaces,
numbers and unrelated keys will be
ignored. J he back arrow key will dear
all you have typed in and let you change
your answer. If the answer is wrong,
i he iwretri unjiwcr vv i 1 1 be giww Your
score will he shown as a percentage of
correct answers to the total answers. A
new pari of the heart is selected and
the routine is repeated.

The heart is only one of the many
KiihjetMS that L h an htf teamed with this
type of program. To seteU yom own

drawings and words, simply repbue i|u a
Ones in Heart Quiz with your own. To
make the drawing easier, a temporary
routine at the end or the program will
help. This will let you find line lengthy
DRAW statements and circle sizes.

I have* included such a program. Type
in listing 1 at ihe cud of the program
into which you want to put DRflu
statements* From the menu, select the
function you want: UlKCLE., LlNL t BUX
or DRAW. The joysticks and keyboard
are used to control the size and shape
of the added famine; typing * and

pressing ENTER will give the statement
needed for the added feature.

You can use the space 1 left to put
each new graphics line as it comes up
I see remark lines). If you prefer, you
can put your lines anywhere as long as
you put RFTliRn n\ die end of yoin l^i
line and change the GtJ^UB line number
on Line 540.

ill you have any questions about
Heart Qui-, you may contact Denis at

GAME

An arcade game calling more for
menial than physical reaction,
Number Bumper works in
Color basic usid — with the change
noted an Line \ 50 — on the MC-1CL

IVe corrcspfjndcd wilfo hundreds of
Color Computer owners, and while we
all share one interest — the CoCo —
we are a community of differing
physical abilities. I know of a recovering
stroke victim who use* two fingers of
ihc same hand iti type the basic listings
found in the ratnrow. And there are*
users with degrees of impaired move-
ment or paralysis caused by a range of
circumstances.

Number Bumper is a game that such
liters can play. St is not meant to
ton descend to anyone's physical dis-
-ihliiy, but rattoti tu equalize play
among the range of our CnCr* family
by making the gist of the game a mental
decision triggered by the Up of any key,
I think Number Bumper will be chal-
lenging to all who enjoy recreations
catling Tor nimble wit*.

( Rkhard Rameita u it farmer newt-
paper editor who now works ax a •writer
for a California hospital. He hux
published more than 200 Color Com-
puter programs.)

To start the game, type run and press
Entfr i Orange bar> are drawn at top
and bottom of the screen, wiili ihc word
"SC URE^ at the bottom. Tap any key
to start the game. As play begins, a
number ranging from zero to nine
scoots across the top of the bottom
orange bar. Pressing any key shoots it
id the lop of the screen. It rests where
it hits,

If a number Is allowed io acuut all
the way across the screen. 10 points arc
deducted. Points are scored by shooting
a number up to rest against a higher
number Fur example, a '9' has stuck
again*i the tup bar: a*r comes scooting
across. A key tap srnds the l V upward
10 suck against ihc *9\ Since 9 - I -
8, the turn is worth eight points. There
is no score if the top number is lower
than the number that hits it

The game ends if two of the same
number end up touching, either side by
side or top to bottom. ThU produces
a mixing sound ♦ after which a run ( her
game may be started by tapping any
key twice,

(For those having any questions

The authors appear to have done thorough research on

You have twu opportunities to answer the questions

However, t found the flashing prompt "Press any key for

Get Organized With
Easy-To-Use Merge *n Mail

I need lo pet organized. My bass keeps telling me to
get organized, my wife thinks I should get organized and
my kids think. I should get my siuff together. It 's nut ihut
I tun a sloppy person, I ju»l use the "file by pile** mcilmd
nf si mage and ictticvaJ. When something comes in I need
to keep, 1 put it in a pile. The problem is that I end up
with piles ol stuff here, there and everywhere, and 1 spend
too much lime rooting through piles looking for stuff I
know is there, but 1 just dont know where.

All I needed was the correct software w help my Co Co
store things and retrieve thera on command in a usable
format. To my assistance comes Merge Vi Matt fioin ilie
folks at Com p ait rw a re. Designed primarily as a mailing
list maker, this program has additional capabilities and
also functions as an easy-to-use mini-database.

The emphasis with this program is on ease of use, Unlike
dBASE fll t which I have great difficulty using because
of its complexity, Merge h Mall is wry easy 10 u«

The fields which wmitrl mo ma I ly he used In generic
4 mailing list are preset. These fields are;

Maximum
characters

Last Name li>

First Name ! 3

Company 26

Address 30

City 20

State 2

ZIP 5

There is also a set field for telephone numbers,
Additionally, there arc up to 12 Fields which can be
configured by Ihe user, For these fields, the user also
specifies the number of characters each Held contains. Once
these fields are set. changes can be made to the data stored
in the data file, but nut to ihe fields themselves and ihelr
characteristic*.

The*e additional fields can he used to store information
which you want to store about the person* but not
necessarily print on a mailing label I such as birthday,
spouses name, etc.). Examples are given in the well-
documemed instruction manual. These would aptly pertain
to ;i computer club In I hut instance, pertinent dttla could
be the number of drives, maximum memory and date dues
arc due.

Merge h Mail can also print out the data on standard
Wi by J J -inch sheets as well as labels. Two choices are
altered: long lis ling with all the programmable fields, or
a short listing with just the name and address fields.

For primers* offering com pressed priming ( 1 37- characters
in the iiuriiiHl HO-culunin spiicc), I lie jiio^ijui iilluws )iiu

to enter the printer conl ml codes fm cuiKpirvj^l nm\
expanded typcstylcs to obtain maximum function hum
your printer. My D MP- 1 00 does not have this capability,
so I used the standard short listmg mode which worked
just fine.

Once data has been entered, it can be recalled for
ririimnifiikia t change*, uddinons vv deU;iion* r Several
search option* arr given In nssisi yon in finding a particular
file in the database. As new persons are added in the
database, the entire lite is re-sorted by last name. When
labels are printed, you are given the option of re-sort ing
by ZIP code, since significant mail cost savings are available
if bulk mailings can be presorted by ZIP code.

Merge h Matt also has u feature which allows you 10
merge the information in youi database into a form letter
that won't look like a form letter. (Hence the ** Merge"
in Merge >t Mail).

After composing a letter on any ol the disk based, ASCII-
generating word processors \ Color Scripmi* Telewriter
changed to ASCI t output, VIP Writer , etc ) T you put Control
cuttes where you would normally put the name, address
and the other data which is now contained in your database
liks. Merge Vi Mail then pulls this data oul, prints ilie
information, justifies the remainder of the text and
continues onward until the List is completed. Votta*. horm
letters without the "form letter" look. My friends and
relatives are going to be surprised when they start receiving
letters fiom me. IVc even put a field for birthdays in each
file so birthday cards will be nn lime

My list ol suggestions for improvements for M*rgt> to
Mii ft is a short one. I he first eight fields are fixed regarding
subject and field width. While this simplifies the set-up
routine for most mailing applications, the Lack of flexibility
regarding field width creates some problems.

The 71 P cudr block h set to five spaces, thus eliminating
the ability to use the six-dlgii Canadian alphanumeric postal
code. The first name U scl di LI spaces F.nough tot i*nc
first name, but L ran into problems with entering the first
names of married couples 1 wanted to include on' one Idler
(Le,, Dear Mary an ne and William}, ihe ability to specify
ihe field width in the first eight fields would eliminate ibis
problem, or jus) adding a few more space* io these field
width) would help.

U you are very good at BASIC, you can go into ihe
program and modify it. but he forewarned that it was
written to be memory efficient, not easy to modify, 1 took
a peek at the listing and gave up,

The other limitation is only one mailing list can be on
one disk, even if it is a very short one. Not a big problem,
except that disks (and ihe required backups} arc not cheap.

Merge *n Matt requires a MK disk HoCo. This is not
a problem with the progtam. as the features, justify ihe
memory required l il jusi limits the number of potential
users.

Overall, 1 consider it an excellent program — more than
jnsl » simple mailing list and less than a full-featured
database. Considering the |nici\ ji rs quite it value.

Personal Bookkeeping 2000
Has Significant Improvements

Pe.rsnnai Rnnkkrppmg 7QW is ho enhanced version of
Personal Bookkeeping 84. In the November 1484 issue uf
THE RAINBOW (Page 214), I did an t\ tensive review of
Personal Bookkeeping 84. This version is basically the same
program, except the author has modified many of the areas
I found objectionable in the original review,

Tliose improvement* include the ability to easily define
your own expense calegoiirs rather lhan have to live with
those selected by the author. En the nnguisd program, it
only provided for check numbers of three digits; you can
now enter four dipils. 1 think this will meet the needs of
most users. You can now easily add service charges to
your huto urn!* which makes it much easier to reconcile
accruals

In the earlier version, it was adorned we nil would make
entries into our bookkeeping system rm it daily basis.
Because of this you hod to go back to the mailt menu
to change dates. With Personal Bookkeeping 2000 that
is not necessary and, believe me, it makes data entry mn . ;,
mure over friendly, especially for those who enter these
lype records no a weekly basis.,

Another significant improve meoi is in i he documentation,
li s more clear than (he original and ihr mtb/cw has included
a tutorial that shows how to use most of the major functions
of ihc program,

Personal Bookkeeping 2000 is a powerful program that
is n*ri friendly. It provides the user with a wealth of
information li requires 32K ECU. disk drive and printet.

Software Review,

Probuloto — Not Jusl A
Random Number Lottery

tC& in the news u loi lately: "Local Citizen Wins Millions
in St Air 1 rtltrry " Wilh matt And mar? si ales gelling into
i he lottery famines*, Probaioto. by Gary Olandcr, may be
just the ticket for you.

The documentation points out that Frobafoto h not "just
another random number -^enerp tine, lottery program"; the
object, however, is to pick the numbers to win you millions.
This machine language program is available on tape for
16K RCB. while flic version I received ml disk requires
m ECB (or 64K under J DOS). It is well-documented
and the program is menu driven — it's so easy to use
that alter going through the documents lion once, vou'U
pcobabh file it away.

The user is prompted for information about the particular
lottery being entered: how many numbers are picked and
out of how many numbers. The example given for a regular
lottery picks six numbers, from one to 40, but these
parameters can be changed, Output can be routed lo I lie
screen, or to screen and printer. Printer Baud rates Lrom
300 to 9600 can be selected,

The first three selections from the main menu are strictly
random number generators. The first picks three numbers;
{zero to nine), lite second picks font nuinbci%(£cro In nine)

and the Lhird picks si\ numbers tunc lo 4U>, lor what is
called the regular lottery game.
The fourth selection from the main menu is labeled

make* the program! more than jusl a random number

LTnri .inn Mil: i:vcr has l\tC OtHlOR ill \r[ltnj' n;- -Ac i^l trs'

data files untng lists of past winning numbers which arc
available where lottery tickets ora purchased, litis is easily
done by tinswering prompts to input the number of limes
each number tone to 40 or zero to nine) has been a winner.
These files can be labeled and saved to disk {or tape) and
a hnrd cupy ran be Ikied by the primer

The weighted random sciectinn prnces* can use (hesr
data files in one uf two ways. If the user feeb tli at the
process used to select winning number* picked iwicc as
many ts as 17s in the past, and is, therefore, likely lo
continue that trend in the future, Probalow can weight
towards the tnost-picked numbers. In the example given,
I he program would be twice as likely to "randomly" select
a 4 m -a \l Jf howrvrr r fhp u«r feek thai ladv I -lick
plays her hand such that poor old 17 is due. the program
can weight toward least-picked numbers.

This weighted selection procedure can also be used to
set up data files which will favor the selection or your
lucky numbers, or conversely, tend to avoid your unlucky
umuberv

To test this weighting process, 1 wrote a shall BASIC
program to generate at random regular lottery-game
winning numbers. 1 input 60 sets ot six numbers into a
data file and used this lo have Prvbototo moke selections
weighted toward the most-picked numbers, 1 then had
Probahw make an equal number of selections strictly at
random When ihrae results were compared in my origin nl
list, the weighted selection s produced 7 5 percent more
matches than the random selections. My original list was
fairly wc Undistributed. More pronounced variations in
frequencies m the data input would have added to the
weighting effect and increased thai percentage.

My criticisms of frubaioio are very minor. The data
file print nut produced by the program ]s u narrow column
near the left margin consisting of numbers and the times
each has been picked. For a regular lottery game this
column is 40 tmes long, using much more paper than would
be necessary if the output were better formatted. Also,
when finished with either printing or saving a data file,
the program returns to the beginning with initial questions
Hlitinf your 1 1 ale's lottery It would be more useful lo return
to the main menu at ilm [mint. 1 astly (dare 1 he so picky''),
the word "array" is misspelled on one of the screens.

If you ore into playing a lottery and believe the game
is truly random in practice as in theory, stick lo the random
number generator already in your CoCo, On the other
hand, if you feel thai Lady Luck is not always random
.iinl want to use some sophist letted m;i I hematics lo bring

Dutigfftti Que at by Cumputcrware is a graphics
Adventure game uising a LiHuhinjiiniii nj ihc keyboard an J

to play the game. 1 he action is similar to games played
on home video arcades which involve using a joy a lick with
a Touch pad combination.

In the game, you are a lad named Brodric who has just
unite of a ge . H e h. a restless lad and decides to go out
into the world and mate his fortune His father gives
Brodric his inheritance, a rusty old sword which ts nimuicd
to be magical. As Hrodnc travels to the Eaat, Ik hcao

story short, the emperor named Darius dies of a pltiguc
and, having no heir, decrees that the finder of hi • crown

answer the questions: "Do you want to have the objects

senuul being a more complex maze of tunnels, corridors

1 here are several types of treasures which, besides
increasing your wealth, also move you up the social ladder

Print Master Helps Master
The Screen Dump

By Dp mi K A. Church

Prim Mii\(vr, fiom Dataman International, is a two-
program package thai helps solve the problem of getting
the graphics screen to the printed pugfc. You are thinking
that this is a graphics screen dump program. Yes, that
is what it is, but it is different and more sophisticated m
several ways.

Print Master w<u, ir\ iewed from the disk version* It Is
con mined no a single, copyprotected disk and requires
a 32K Color Computer, it has some features which take
advantage of a 64 K CoCo It is also available on tape.

I he main program is titled PMA ST{ for * Print Master").
With it you select trom an extensive list of options designed
to load your graphics screen and print ii out any way you
want it. You select and execute option* almost exclusively
with joystick 4ml foe hut tun. They call it "clicking the
mouse" and it will work with tt mouse, but i found the
joystick more convenient.

Eos* of use for this program is not very user friendly.
The question Is, will 1 instinctively know what 10 do from
the choices presented! lo end up with what 1 want? The
aritwn ii, "No " Rut I'm one of those who doesn't think
"instinctive " programs are ail that possible; I expect 10
need a manual to operate a complex program, 111 past

say that Print Master presents easy options to those who
understand the options. It also recovers from improper
input without damage to your work, Though you can
HKfeAK in the program, the graphics screens are all intact
when you rerun.

The menui<ivnil»r)!r hi c the Main Menu, File 1/ O, Image
Dump and Dump a Screen. Graphics screens may he loaded
from lapCn disk* Graphicom and CoCo Max, Image dump
pafumctcrb arc pixel iize (con I roll ins the we of Hit.- imaij,ei,
inverse* rotate, dumping more than one graphics screen,
shading, tabs, dump using text, as well as a choice that
selects a user-programmed option for unique primer cudjes.

Before dumping ime or nmre graphics scieens, you can
scicei the PtiOOE and which screen (or portion of screen}
you wish to print, You can have two PtfDDC 3^4 screens
in memory at once: eight if you are in Pf1UU£ a. A MK
computer gives double thin area. The added memory alto
makes it possible 10 store screens in high memory, luad
a second screen and print multiple sercrux in a usei-sclccicd
order

Before any image can be dumped, however* the printer
dnvcr must be loaded. It you have n primer ot the following
type, the driver is included wilh the program (with mare
promised in time); Tandy, Gemini, Image writer, C. It oh,
Spirit 80 T Mannesmann Tally and the CGP-II5 If you
don't have one of these printers, ui you want to employ
custom ende* in the printer driver* the second part of this
program comes into play. It is called The Cuitomizcr,

The C'ustomijcr creates a printer driver for use by Print
Master, e ven though il is menu driven, it requires a good
understanding of your printer. The manual warns that using
The dtstomiier may be difficult because of poor primer
manual;. ;mtl ihe oiiuph-Miy *i\ dm geiiphii^ jti inliug (Tl<al
warning rang ii ue on \cvcral midnight sessions for mcj

Here is a sampling of knowledge needed to design a
custom printer driver. Baud rate, number and configuration
of pins in the print head, Most and Least Significant bit
order required and the control codes you warn sent to
the printer in sets of custom designed strings. The
Cusiomimr includes a Store Ruffei T Clear Ruffe i ant] Test
Gptiafts capability. Bad control codes can be selectively
replaced before saving the file. The tile you create Irom
Tlie Customer is the printer driver you load to Pmti
Master before making a screen dump,

As 1 mentioned, the manual warns about the complexity
of the program. The manual itself is an impressive looking,
ihrronng hint Iff [niine.l in brown on brown in a cuiinux
two-column formal. It has on index, a helpful appendix
and reproductions of program menus and other illustrations,
t suspect the manual was prepared asm? this program plus
two other Dataman program* helpfully explained in
appendix D: Text Master and Graphic Master. Despite
these assets, ii srill requires a eairful, L-uvrt-uwovet reading
to ir*r l he piogrnm effectively.

I obtained pr to touts of their test picture and a Gtaphfcom
picture you select within Print M 'aster Irom the Graphicom
menu on both a Gemini- 1 UX and a Line Printer VTL
Options to control theme and rotation of the dump worked
well. (No, the program doesn't make the LP VII any
quieter. \

Now f imift fanll litis pmgrnm Iking my Oemini-lOX
printer, the graphics output invariably left a blank line
between pnnthcod passes. Using one- by -one pixel size, the
blank was one pixel in size. Larger printouts resulted in
larger blanks. "Now is ihe time for The Customize^ I

Personal Program Protection
With EZ Cassette Encrypt
And EZ Disk Encrypt

If many jieople use your disks or tapes and you don't
want them to be able to access nil of the program*, here
is a solution. This solution is very easy to twe for disk
and a bit bulky, but workable, lor cassette.

EZ Dtsk Encrypt and EZ. Cassette Encrypt take the flic
(on disk* any type of Hie; on cassette* only ASCII files)
<Mi<) eat'lusivr-OR it with any password you choose. Not
an cAUcmcly >tupemtou* fear, but it does the job*

With EZ Disk Encrypt, the program reads the file off
disk a sector at a time, cxclosivc-ORs it with tlic password
and writes that sector back to the same place on the disk.
This could present a problem if on input/ output error
otvurs during the process. Only part of the program would
hi* niL-rypird and it would nm be recoverable* You mwti
have a backup copy "f \Uc ilk- t*rfurt you use this program I

With EZ Cassette Eturypt. the ptogriou orach in the
entire Qlc before it starts encrypting it It Own dors its
job and prompts for a name for the output Hlc. This way
is DOl as fast, but it is mere reliable than the disk method
and the only method possible for cassette. With this
procedure, ihe file can only be so long* but with the disk
procedure, a file of »ny length v-m be encrypted*

To decrypt a file, renin (he piugraiu using the exact
same password- U will be decrypted because cxdusiveOR-
dig is the exact opposite o! itself T

Unless you shore disks or cassettes with other people
and have confidential files on them, 1 see no real need
fro ihese pi obtain*. But if you require such protection,
then they will work well for you.

blank; a few mare and still not a sound. You panic. How
could your masterpiece have crashed the system? As you

spent three weeks drawing finally appears. Now you realize
I he problem is something much worse than a system crash
Your program is S-l -O-W!

A high speed POKC won't help now. It is time to rccodc.
but what pan of the program? EZ Preftkr by Land ware

saved at TEMPI BAS. The new version will then be loaded
and you muvi type BUM (o execute the new program.

Running the newly created piog^am is exactly like
running the old version, except for a speed slowdown as
the profiler tabulates the execution data. When the source
program is terminated bv an END or STOP command or
by pressing break, a subroutine thai is appended by EZ
Profiler m\m be executed. This routine will Jump the
tabulations to either the screen or a printer.

The result is < imply a count of how inatiy limes each
program line is executed, which, according to the
instruction sheet, "will show . , , which loops in a program
are most heavily used, These loops can then be rewritten
to make the overall program much foster/'

The major deficiency of EZ Profiler is thai ir offers no
suggestions lo speed tip the tode, nor dues it even hint
at how In detei iitinc width i limine* ate tiuly "wasteful"
and which routines art written as tightly as possible. (For
example, a FOR'NEXT loop might have been executed 500
times, but not neeessartlv be wasteful.)

The instructions that come with the program are
MdrtjUiiie enough to operate the program, but really arerfr
enough to put I be program lo use, which is the mutt
important reason for using a utility.

Other problems with EZ Profiler include the additional
processing time it odds onto the source program (almost
a i.QQO percent increase) and the additional memory
required. The time factor is only deadly in applications
where program flow is greatly changed by timed responses
(such as games). In I hi* ease, ihe program b of dubious
value.

The memory factor can be dchabihtating. The program
appends an additional 2U characters onto each line which,
oo longer program mi nji endeavors, could prevent the
program from loading into memory.

EZ Pro/tier it not a program that will answer all
programming woes. It wilt help streamline software, but
not unless the programmer is willing to put io much mure
work than the program. EZ Profiler is essentially an
extension of Basic's TROn command and should be treated
as such, H does exactly what it claims, but be wary of
reading 4ti> other uses into .t pr.ienlial uuivJulm-i'-. '.bt '.iJj
beware that although EZ Profiler can help hone their
pmgrH mining lechmLjucs. the work is still op lu them,

EARS Pioneers The Way For
Spoken Command Response

By Randy Graham

Personal computing is a pvox of cuke Just turn it on
and start typing: it all appear* right ih«e on the screen.
If you make a mistake, back up and correct it Write
programs in many languages* Run so It ware for word
processing spread sheeting - even play games, Print it all
out leiier-perfcci then save it and share it. Nothing to it,
1 1 ulcrs^ yim have no hands to type or no eyes to see the
screen,

I work with handicapped people. Jonathan whs a lineman
before his accident Because he severed hin spinal cord,
he is confined to a wheelchair. He has very poor use of
his urms: he needs help to dress and to eat, When 1 met
him, he was beating everyone in the rehabilitation unit
m i lic^ I ihouglu thai a good chess player ought to make
a goad ami pule* progiaruwer,

Paul has had cerebral palsy since birth. HccHngci mound
With crutches although it is difficult his arms and legs
just wont do what his brain tells them, His speech b difficult
for most of us to understand*. He is a college graduate
and would like to be a writer, but trying to type can be
a tearful frustration for him.

As a result of a disc ase, rveryihmg looks blurred to Betsy.
She can manage to read with a magnifying glass* , holding
the material close to her face; she has not hern able to
find n computer screen she can read.

For Jonathan and Paul and Betsy, the keyboard and
screen which give its access to all the marvels of personal
enmpuiers are just as formidable harriers to computing
careers as the six -inch curb which locks them out Of a
> hopping mall 01 an office building. We uin an notches
in the curbs and build ramps around the steps Whai can
we do to open up our favorite activity to some very fine
people?

It was for these friends and others that i Mew to the
K MN ROW test in Chicago to find out what Rich Parry
and Lester Hands were up to ni Speech Systems, It was
tun meeting them and I because mi excited about thdr
work that 1 brought an EARS heme with me so I could
join Lhe adventure, EARS | Electronic Audio Recognition
System) is a device and program through which a Color
Computer responds to spoken commands.

Yea, J said spoken commands! No other computer has
it — jnsi CnCo We are coming Along with voice
synthesizers which can elect to me ally vocalize text in
memory, but going the other way? Little more ihau a >c«i
ago I attended a conference in which an expert in the Held
said that speech recognition was not even on the horizon.
He was wrong. Say "hello" to the expert, EARS.

What You Get

In a nice plastic envelope you get two pieces of hardware,
a piece of software and a very good manual. One piece
of hardware is a ROM pack which contains the magic

djid i he til lie* piece is u headset There are no earphones
in the device, it is just there tn hold the microphone close
to your mouth. The headset plugs into the ROM pack
and you know where that goes.

The software | tape or disk) contains a machine language
program, a utility and ^ei-eral demonst ration programs.
Load and execute the EARS program and you are in
business. To i he user, the effect is that all of your Extended
Color BASIC ROM still works but some new commands
have been added. Tunc lo stall learning

Hnw it Works

LISN is the fini n*w command vou meet. Like all BASIC
commands, it can be used in direct mode or within a BASIC
program. Type LI5N *l~ and say "one," You have taught
OCn/F.ARS in find word. Lets note that you have also
taught it your accent — and language.

EARS is a "spcakcr-dcpc ndc nl '* sy item. The user teaches
the machine and thereby sets up a unique relationship
There is nothing romantic about this: it seems to be the
easiest way to do it. A "speaker-independent "system which
can icvugnkc any voice in any accent, pitch and inflection
must be much mote complex. This way* whether I say
"one" or 4 >uno" or "cin," when I say it again, EARS will
respond with "'one," Space is reserved in memory for a
speech synthesizer Uke Vaice. If you tell EARS to SAY
1l oner it will apeak U from the speech system,

OK, I have taught EARS one word. I can now repeal
dial process. In its present shape and form, EARS can
*Mearn" 64 strings. Apparently, (he program sets up a two*
dimension array. One clement is a siring of up to 1 6
characters which J type an. The other cfcntcnl is a voice
print of what t say into the mieto phone. EARS calls this
pair a "template." Let's see what i can do with this arrav

MATCH lets me use the vocabulary list. After this
command, I say "one"; there is a noticeable pause, then
i he screen prints T EARS has searched the array of voice
prints, found a mairtb and printed the character string.

Let's note ngum that the relationship between the input
string and the spoken part is what I wont it to he.
"Gadzooks" can make the computer type out "My name
is Randy 4 * if that is the way t made the template.

What if I forget my own list? TLIST will produce the
string pari of the list of templates for me one screen at
a time. TSAVE will save the whmlc- tiii <.•[ brings and voice
prints to tape or disk (EARS checks to sec which yuu
are using); TLOAD will load a list so I do not have in
do it over every lime.

Yuen I Programming

Now fin | tic great pan. I have taught EARS the digits,
alphabet and as many basic com mantis as it will hold.
Time for another command,

DRECT instructs EARS to accept BASIC statements from
me. 1 can say M o ne- zero- a-eq uais-onc- two-ihrcc-c nter " and
a basic line appears on the screen. Then, "two-zero-pnnt-
a-cnicr* and the second line is in place. 1 can say "list"
and it will (because I ridded the "enter" to my string); when
I say 1 *run. %t it docs it! Primitive? Yci, but I wrote and
ran a BASIC program with nut touching ilie keyboard! I
feel like I have the first horseless carriage in town.

While in DRECT mode, the computer will accept
keyboard input, but it will continue to respond to voice
commands until turned off with BREAK.

problem you may encounter on the more difficult levels
is a greater chance of fire and disease, which wilt diminish

to switch from the program disk to the data disk when
prompted. According to the author, the package is desijmed
to truck liitle league, high school college or any level
desired. 1 1 is uot a league secretary but can be used for
one if desired. It is primarily designed around nne team,
with individual learn and opponents stats.

Football is completely menu driven and very user
friendly Single key entries are used when possible, and

to-understand, nine- page documentation booklet is
included 10 give you a general overview of the package.

After running the boot program, you are a<ked to enter
the number ol drives and Baud rate of your system. The
main menu program is used to move from item to item.
When returning from a support program, you are relumed
to the main menu.

Included with Football are two disks: One is I he system

is a sample data disk with 75 team mem tars' siais recorded.
I did si ail my own data disk hi id just used my imagination
tor all the individual player's statistics, but soon gave up
us the task was very monotonous because of all the different
statistics to be entered.

Finally, I decided to try number 1 1 from the main menu
(RUN TEAM SUMMARY) using the provided data disk.
The following was printed on the 21-page team summary:
my score nod the opposing team's scores in each quarter,
the total score, pen allies, penalty yards and first penalty.
Then my team's roster was printed, which included each
player's number, height, weight, year {or grade I and
position played, Next* for each of the 1 1 opposing teams
recorded, each of my player's and the opponent team name
was primed, with the total quarters played and number
nf plHyhi for each individual. This amounted In about \2
pages. After that, the passing stats for certain quarlti Iwk v
were printed, including passes attempted , passes completed,
yards, intercept,, first down and touchdowns,

To save space, I will only list the last six slat sections
primed. Rushing stats t Receiver stats* Kick off team, Kick
reteival team, Punting team and Punt receival team. The
last two total sections were for defensive and oppomn;!
team stats.

There was a small problem with the PRINT/ BAT
program, CoCo gave me a syntax error in Line 170 when
the program began to run. This was a result of a FILES
3 statement, in conjunction with my 1.0 disk ROM which
lias a few bugs A simple fix for this is to type PluES
3 from the command mode before running Football.

Overall I was impressed with ihc case nf use and wide
vanely ol options and functions. If you arc interested in
keeping track of your favorite football team* and don't
want to keep notebooks full of your sloppy writing, help
our economy and purchase Football Statistics Package*

Sound Generator For The
Sounds Of Your Life

Sound Gprtprator is n program I hat allows I Hp cntlivn
design ol sounds, As the instructions explain, son nd is a
combination ol sound waves and loudness. With this
program vou can enter anv wove form desired. You are
also allowed to enter the "sound envelope," which is simply
the varying loudness of the sound. Either of these can be
entered aphis. ally or numerically

To get started, the instructions tell you how In load in
cither of the two sets of wave and envelope tables recorded
on the program tape, they then take you step by step
through most of the commands avail able, s ho wine vou
how to use them, The first command is to allow you to
draw or view the table. The second will allow numeric
entry nf either table. Their art commands to allow changes
of pitch, number of envelopes to be played and caueite
save and toads.

Others allow the listing of the table values to screen,
delete current table from memory, stretch table, end
program, shrink table and duplicate table values. Three
of these need some explanation. The first, ttretch table,
takes the current table and duplicate** each clement,
truncating the last half of the current table. Shrink saMe
will delete every other clement, [caving the last half of the
table empty, The lost* duplicate values, will take the portion
of the table entered and repeat it until it reaches ihe
maximum table length, allowing you to enter only part
of m repealing table.

There is one mhei coniohind wMl 1i iv r vrllrni 'Vi vtnmd
synthesis, This command will allow you to create a machine
language sound effects routine. The way it works is by
prompting for the pitch and number of repetitions ol each
note to be played, It will then use the wave form and
envelope tables 10 play each of the notes entered. This
u great fur playing xongs.

If you are interested rn \mim1 synthesis 1 rerommend
Sound Generator. Although there *cems lu he an
expectation of a previous know lege of how sounds arc
generated . the instructions are helpful enough to get you
started. From there you eon experiment and learn what
you didn't already know.

BASTXT Puis A Variety Of
Options At Your Fingertips

By Dale Shell

If you do a lot of ha&ic programming and you are getting
lired of seeing I he same i • leJ green and buff MTcen, Valley
Mien* SyMrius unty have just ointe to your fescue wilb
BASTXT BASTXT was developed to enhance basic,
adding 21 more commands and eight functions* ft also
adds high resolution text to the graphics screen, BASTXT
requires 64 K and at least one disk drive.

There are two teJtt screen mode* with BASTXT. 32 by
16 and 42 by 10. The 32-by- 16 mode should allow most
BASIC programs In run unmodified. The 42-ny-fft iihmJc
is very' handy, but remember when the PRINTS statement
is used, it will not cover the entire screen, Mode 42 will
also not allow any color or inverse highlighting commands
to be used, Some of your BASIC programs may have to
be modified, but this mode allows almost a third more
information to be displayed on the screen

Inverse highlighting i* invoked utirig I lie fNVFRSF ON
command. The INVERSE command can be used two ways,
INVfcRSE can totally reverse the text and background
colors. The second use. highlighting text, its vcrv useful
to call attention to special words on the screen.

Another way to bring attention to certain parts on the
screen \\ to underline words This can be dune using the
I JUNE ON /OFF command, It can he used to underline
any text printed on the screen. Once this feature is turned
on. it will underline everything that goes to the screen until
it is turned off* even if the program running is stopped.

MA S TXT has many features to enhance the appearance
of your screen, Smooth scrolling is available; with
SMOOTH ON, the screen is scrolled up a pixel at a time
ins lead uf a line. This slows I he scroll i rig down comidVi ably
Another vt.iv to >low tilings down is with the SPECD
command. This command changes the speed at which
characters are printed to the screen. I he detault, SPEED
0. is Ihe fastest, with SPEED 255 being the slowest —
it really creeps along at a snail's pace. You can choose
any speed in between,

BASTXT nUi* ha* a PA OF command which causes the
scrolling to pause every time the screen fills up. Two other
commands allow you to tab to any horizontal or vertical
position (i.e., X I AH and V I AH}, A WINUUW command
has also been included. This command allows you to protect
from zero to 14 lines of text at ihe top of the screen from
scrolling. You can still use PRINTS* to get into ihe window,
hut the window is protected from commands like CL5 and
WCLS. WCLS is a fancy way of clearing ihe screen. It
makes the screen sort of "dissolve'* away. Vou can also
disable the RRS.Ak kev with a simple command. BREAK
ON OFF.

There arc three different cursors you ean choose from,
01 you can edit and ticalc your own. The three I hut come
with BASTX7 include an underline I non definable I, a single
block (singtc-characicr definable! and a man waving his
arms (seven character definable), A SCAN command is

GotubsM 19BS THE MlW»0w 205

The neat turn commands, BLACK, RED, BLUE and
NORMAL, provide four different colnr\ of piinting The
NORMAL is close to BLUE but appears to be a different
9 bade. All these can be used together and m conjunction
with the INVfcKSfc command; they con yield some
interesting displays, [NIT is used to put all the commands
back to I heir default values and EXIT is used to disable
BdSTXTmA return your nystem back to normal basil.

The cighi function* available are com par able ki assembly
cade instructions. I will not describe their function* but
will list them. If you ore familiar with machine language,
then you will probably have & good idea of what they
do. They are. COM{0-255), ARSL<0-255}, LSUQ-255) h
ROL(0^55), EOR<0-65535,0-65535), ARSR{0-255),

Valley Micro Systems has done a lot of work and they
have developed a very useful product, but "every silver
lining has its clouds," as ihey say. 1 tried to evaluate
HASTXVx compatibility with as many DOSs; as 1 could
get my bands on. flAS TX T appear \ to ut fully compatible
with KDOS and works fine if the DISABLE command
is used with ADOS before booting the program. It would
not work with J DOS version Ml; a later version was not
available. Of course, the Radio Shack DOSs worked line.
I didn't have other DOSs available to try,

included io cause the computer Lo pause until a key is
pressed. This seems the *ame at EXEC 44 539*
November 1984 (Page 140). I wish they would put that
command back.

Because the BACKUP command uses some of the graphics
area uf mnuruy, you cannot use BACKUP with one tingle*
sided disk drive- If you have two diives T oi me using a
double-sided drive as two single*, you can use QPCKUP from
one drive to another. Vou ju.it cannot use the single drive
backup, Also, when using backup, toe graphics; text screen
dill go "bonkers" and Ml up with garbage. Don> worry,
this is normal, just press ihe CLfcAR key when the backup
is finished.

One othci guud fcatuic nf HA ST XT is ihr ability io
enter BASIC commands in lowercase, However, if you want
the program to print text in lowercase, you have to insert
the text with the EDIT mode. You must also be tarcfuS
not to enter a command in lowercase when in the EDIT
mode or you will get the old SN Error.

Now fox the bottom line. All considered p I believe
DA S TXT is <a very useful and well -dime program if you
arc aware of its limitations. They may concern you or they
may not be limitations at all. if you do a lot of
programming, vou will enfov tnt different opiums you will
have at your fingertips. The WINDOW. ULINE, INVERSE
K tu .J commands can provide some very impressive displays.
Rut, if ymi give or sell your program to someone who
docs not have BASTXT and you uxr some of the effect i
and features of BASTXT, the person who geis the jnogtmn
will not be able to use it. You may want to contact VMS
about including their program embedded in your own if
you want to market iL

The second function of LoLo tcho will take whatever
text it lyped from the keyboard and send it to the printer.
To n w this function, you need to press the shiki and down-
tut ow keys hi the same lime. You can end this duplicating
process at any time by pres-vng the shift stud down-arrow
keys a second lime.

As I have a 16k Extended basic computer, 1 was only
a We to try oul the first version ol to Co Echo. 1 was happy
with the ease of operation. Although the instructions J
received with the program were very short, i had no trouble
gelling it loaded stnd running.

Since I wanted in I ry nut the 32K veranin of I his program,
I called my local Radio Shack store and explained what
1 wanted to do. When I got to the store, Don (the manage*
of the computet center I, took me to a computer, set up
the printer and let me go. With a ,12 K computer, you need
to type CLEOB 228,32580 and rMhH before you type

P nRtlrliFXFCi and ENTER Tllis will load ihc program
into the lop of your computer \ menuny niu\ oul of yoiu
way. You use this program in the same way vmi usr inr
Ink version. Once again, I had no trouble with the program
operation.

Some of you might be asking yourselves. "Gee t it sound*
likr h r..mil f 3 o ,itt* . 3t i i *hai i.-j -oicl T Ljs.e if for? 1 ' Well
let's «tay you would like a directory of pm^iiiw No

and you will get a hard copy of the directory. How about
if you Ye typing; in a Basic program: just turn on ihc
duplicating process and while you Ye writing your program,
yottH be getting a hard copy of the listing at the same

Echo. Vm sure if you hay iE you wfII find more.

As you might have already guessed, I think C<tC*> fit ho

Telepatch — An Excellent
Enhancer For Telewriter

By John R, Curt

When J first got Telcwriter-64 last year, I was in heaven,
1 could n I believe the program's versatility and case oi ii.se.
I didn't have lo study the manual and several other books
Tor a month before I could start using it, I did tit have
to remember complicated command strings. Most of my
il nun men I* were lea* than >t* pages lung This wai the
word processor I had been locking for.

As time went on, though, 1 began making a mental wish
list ot things Telewriter -64 didn't have that it needed. This
list included key dick, block move, key repeat, easier disk
I O and more. Telewriter-64 was still the word processor
Tor me; t just wished It had some little improvements.

F nter Spectrum Prujrt;!** Tfhpatch by Bob Van Der
PocL As the name imp Lies. Tetspatrii is a Tftswritrr-tU
enhancer. It adds ail of the above improvements and moic.
After using it for a week, I cant believe Telewriter never
had the enhancements thai Telepatch provides,

Telepatch requires a 6AK Color Computer with at least
one disk drive. You must also have the disk version of
Tt>trwri<t>t-64 Fven with nil of the enhancements, the basic
functions of Telewriter^ are slill the *ame

Installation of Telepatch is very simple. First, make a
backup of your Telewriter 64 and Telepatch diskettes,

I Never use your originals!) Next, formal a blank diskette
(known as the destination diskette;. Insert the Telepatch
diskette and type RUN 'PAT CHE P and press ENTER. After
this T all you have tn do is follow die prompts — it* ks
simple as that.

When finished, your new systems diskette should have
the following programs on it: TW64f NEW. TfBAS, *}
*♦* and TSPQOL/BAS. These four programs handle
everything including disk I/O. TW64fBfN is the new
patched TW64fBIN. T}8AS replace* 675^5 as the boot
program */•** it the new disk I/O routine replacing Sj
XXX. S/BlNsndS/ASC. Ill discuss TXPOOL/BAS imer
m the review.

To boot your patched Tetcwriter-64. just tyjje RUN 1"
an 3 press in i re, You will be greeted by a new title screen,
It slates that Telewriter*64 is "modified, improved and made
better in many ways" (it's the truth). You wont notice
anything different on the main menu ot tbtz format menu.
However, the Disk I/O menu ha* been totally replaced

I ne new features added to the editor are: True Block
Move, Visible Carnage Returns, Key Beep. Key Repeat,
Lowercase, Faster Cursor Movement and Overstrike Mode,

The new boot program is the best improvement, With
regular Trlrwrfrer-64, I had to set all of the print parameters
in the format menu before J could print u document This
aggravated me very much! With the new boot program,
you can ad almost all of these parameter* beforehand and
not have to worry about them, I his is made possible because
the boot program now uses the puke command to set the
parameters.

Vein u»ti idio determine whether or not the new features

that you need.

The format menu's printing parameters that can be set
are: page numbering, spacing, queue function, printer type,
one-page function, where lo put the page number,
characters per line, upper margin, boilom margin, left
margin, lines per page and printer Baud rate. As ynu can
sec almost all ol the formal features can be set to any
default value needed.

The editor features which can be set in the boot program
include: editor screen's background color (preen or buff),
key dick oh or off, key click length, key click tone* key-
repeat rate, repeat delay, thirWcpeHl delay, lowercase/
uppercase toggle and ove r strike /insert toggle,

there are also several disk I/O parameters that can be

I will aim explain the TSPOOLf BA$ program. In order
to run I hit utility, ynu must exit to basic from the disk
I/O menu, and type RUN "T SPOOL" and press ENTER. This
utility program allows you to print a file to the disk instead
of a printer. This means the file will be printed to disk
in the exact same format as if you had printed it on paper:
margins and spacing will be observed, centered text will
be centered and pages will be numbered,

This enables you tci prim the Hie at a later time using
a simple little BARIC program with I lie L IHE INPUT

would have to actually use this feature to appreciate it.

The wily limitations of this utility are thai it will only
work with files thai have been laved in binary format and
il will not work with Tiles that have cmhedifrd *Q* (queue)
commands.

Tetepdich tf On excellent program. It adds several

whether you already own or ore thinking of

RS232IO Allows Adaptation
Of Compatible Peripherals

Why do you need an RS-232 I/O program? Well, wr
can start out by saying that the four-pin DIN connector
on the hack of your Co Co is not in itself a complete user
port. Program* are often required to allow the use of this
port to drive RS-232 compatible devices,

Ttir software package* for the CoCo that make use of
this port are, usually dedicated to a specific hafdwarc device
such aa graphics screen dump pjogiams auxi telephone
modems. Hut what if you want to control some special
purpose device such as o robot? What software would you
use?

RS2S210 is a short ( 1 34 byte) machine language program
which provide* the CoCo programmer with the loo Is needed
to run jus! about any prxiphnnl from (hr CoCo purl that
ut RS-232 compatible, The program is multi-saved on
c jj-wef to [ apt; and a nine- page instruction manual is supplied.

The software is not copy protected and backup copies
for the original owner are easily made. The program can
also be saved and executed from disk and is fully relocatable
to any unused RAM area which can be protected with
a CLCflft statement* or il can he stored in a gi aptnes pug*
without the need for a D_CfiE statement

While the documentation Is thorough, it must be studied
carefully. Several spelling errors were found, hut did nut
prevent comprehension of the information. The author
gives in detail how to load and make use ol the software.
Ai written, il provides one start bit, two slop bits and
eiglit dairt hi l* to be either sent or received via the C oCo
RS 232 Port.

After loading RS232fO, il in necessary to Poke in five
variables which control where in RAM the data far tending
and/ or receiving is stored. They arc;

1 ) Data In Count Counts each data byte received
from one to 25b.

2) Match Byte - If the match hyie is the same vol tie
as the received data, transmission stops. It can be

turned on /off with a puke.

3) Oaia In Address — Tells Lhc computet whete in RAM
to store the received data,

4) Data Out Address J ells the computer where in
RAM to store the data to be sent*

5) Data Out Count - Counts each date byte sent from
otic i" 65536

My simply poking these addresses with this program in
RAM, you are able lo "customize" your RS-H2 pun.
Receive and send Baud rates can also be changed. 'One
word of caution, however: This l& not arcady-lo-run, menu-
driven program; rather, it allows the user to develop his/
her own BASIC programs that call the RS232IQ as a
subroutine.

With RS23210 and some BASIC \\\ ugramroing skills, the
user can adapt many RS-232 compatible peiipbernl* that
do not offer companion software for the CoCo.

Nittriguide Lets CoCo Guide
Calorie And Nutrition Intake

Dj i n. Cijiiiici

Nittriguide, by Homcsftfi Company* ts a fun program
trjutblijig l be uwt tu analyst? mcaEs ur daily food intake
in terms of II Ethnic nutrirnK, laitgmv. fnun caluntr* to
cholesterol. Tht program also enables you in keep a regular
weigh l chart, advises on recommended caloric intake to
mcontuin reason nble weight levels arid indicates how your
present eating style compare* with recommended caJorie,
protein, fat and carbohydrate intake.

I Li in iw.ihtrr i dietician nor a nutritionist but t as a
biosiatiyticum, I have analyzed the data pertaining to
m-vc«,iI icAcrjiu li |<ri<jiv-is in wliti h daily milHliorml intake
waa of critical impoi tancc. At picscui. inter \ itujctri is uUrady
mom ion ng the sodium (salt) intake of patient.* with high
blood pressure. Another researcher is attempting to prevent
the re Formation of gatl stones (after first chemically
dissolving them) by recommending a diet relatively high
in fiber and protein. All these undies have shown me the
import nun* of uur everyday iJit;t to our slate of health and
how useful it is to monitor, in nutritional terms, out daily
food intake.

Nuirigukie comes on a disk together with an IS -page
booklet. The disk contains several programs, including a

very targe fond file, which arc all run fmnra tingle pnijgjninT,
NUTRIENT* The programs ajc wiiltcn in Basic, ajiait
trom the tood tile, and an attractive initial screen display
which mixes text and Hi Res graphics. The whole program
it; very dick interactive.

The booklet gives detailed, step-by-step instructions on
hour to usee Nittriguide and how to use each program option.
It contain* the indet nf thr 6S8 typev of food in I he food
file and gives a useful summary of elementary nutritional
information.

The author recommends making a separate disk copy
for each person using N'uirigwde. since the space remaining
on a single-sided disk is limited. As I wanted to try out
the program with my family, 1 copied it file by file onto
a double-sided disk (JAM DOS) wilhmii problems. After
entering RUN "NUTRICNT* and watching the Hi -Re* display
(which informs you the program is written Tor people
between 2b and Ml years ol age, between 56 and 70 inches
in height for women, and 61 and 75 inches in height for
men), you are presented with a menu of options: Set Up
Frruinal File. Daily Nuiriuon Report, Examine Weight
Record, Start New Weight Record,, Rfi ipr Pvaloatiun,
Food File Menu and End This Program.

I he limitations by age and height Affect only (lie
recommendations included in the program; the breakdown
of food intake into nutrient components remains

CoCo Calligrapher Captures
Calligraphy^ Penmanship

"What." you ask. M is a calligrapher?" Well, the phrase
Once upon a lime** is a good beginning. Way back In
the nil! tl»>!k (well befurr. CoCo) the world's scholars often
wrote their manuscripts using a quill pe». A quill pen h
a large leather with a hollow stem which was uac4 to hold
ink land was often plucked from a large, unsuspecting bird).
The beautiful penmanship that often resulted >♦> known
today a£ "calligraphy"; it is 9 skill learned with a great
deal of practice.

Today's caUigmpher* use much more modern tool* to
practice ihmr art Sprriaf prns and inVs allow unique arid
beautiful printed text Most high school diplomas and
college degrees are good examples a I calligraphy as arc
formal invitations to weddings acid graduations* and so
forth,

Now this attractive printing technique can be accomplished
with your 32 K F\ie tided Color bash; CoCo and a bh-
imagc printer. Printers such as Ep.ion* Gemini, several
Radio Shack. Okidata 92. Banana and the Pro writer 8510
can be used. The resultant lettering on the printed page
is approximately 36 point or VHnch high letters which
are variabh s.p,-..*u'iJ ai jn average of upper- or 2h
lowercase- per line. The Epson, Gemini and Pro writer also
rmivide the capability In eentet I he tEM as well These
printers also allow the Use of Condensed letters, which will
double the number ot characters per line. The maximum
number of lines per message is 17*

The disk version supplied for this review worked
beautifully, It contained three fonts: Old English, Gay
Nineties and Cartoon Each was tried With no problems.
The program is menu driven ami requires ihc type of printer

After the printer is set up and online, the program will
ask you to select any of the three supplied fonts nr yun
can select a special font, While the instruction booklet docs
not state what these special fonts arc, the advertisements
appearing in k AiNBOw do list quite a few optional fonts
sold separately. The three that are supplied, however, are
excellent and the results muM be seen to be believed. I
used the Old English fonts to make up several certificate*
for our church members; they were genuinely impressed
and could not believe thev were the result ol a computer
program!

A nice feature of the program is that automatic lowercase
is selected during the menu option to print your message.
Tbi.s makes, your keyboard respond like n typewriter in

It you prelcr all uppercase h you can press SHinr-0 as t$

the program will take you back to the main menu in
uppercase for further selections or additional copies.
Provisions are made to save the text onto tape or disk,
depending on which version you have* *nd also to correct
or change the text.

I hc tour-page instruction booklet is complete* well-
written and to the point. A VU-day exchange warranty is
included ttnd a procedure for making personal backup
copies of the software is explained.

1 liked CoCo Caitigraphcr. It offers many uses for the

A Five-Star Choice
For A Printer Utility

By Larry Birkenfeld

Having a hard Lime getting that beautifully orttstic
creation oft the disk and into a more tangible form for
others? to admire? Never fear, HARDCOPY is here. U is
such a greai printer utility it will make yoti want to hire
an ait 1st just to create picture* to print- HA RDCOPY was
written by Eric White and Scott Smith and is distributed
by Compuitrc, Inc.

HARDCOPY requires a 64K CoCo or CoCo 2, one
disk drive and a primer to match the version you buy,
At the time of thii writing, the only printers supported
Are i fin Epson MX^O/100 T RX-80 and FX-BO, the 1,D.S,
560-G and the Okidata 92. Support for other pi infer* It
supposedly on the way. 5im:r mch vrrsmn suppon* only
one printer, you must be sure to order the one that matches
your printer, I reviewed I he MX-&0 version and it ran like
a dream. Needless to say, I was very impressed,

The package comi-i with a single diskette and a nicely
printed 27-page manual The manual is well-organised,
nicely illustrated (by HARDCOPY no doubt) and is Ljuiic
sufficient.

HARDCOPY itself is capable of using four disks. They
arc I) the HARDCOPY disk. 2) Urophicom Part 11 user
fonts, J) (jrophicom tormal picture disks and 4 1 any disk
containing a Hi- Res picture in binary format, including
those saved from CoCo Max using the SCREEN. BIX file.
I tested using the sample file> nil the HARDCOPY disk
find a small picture made with Graphicom; ail wot kerf fine
bach picture processed is 6144 bytes long. The manual
slates that only 6 J 44 byte images from Co Co Max can
be processed, however, Bruce, at Computet, has informed
me that (his is no longer true. If you have CoCo Max
and are interested in HARDCOPY, you might discuss this
with him,

Before booting the program there are three parameter*
in the boot file that may be changed if you so desire. The
parameters and their default settings are as lot lows:

1) Self-centering or ncn self-centering joysticks: default,
self-ceittering.

2) Printer Baud rale: default, 9600 Baud.

1) Charactci «l default, ASCTT/5FT {Grttphicum Part
//fonts may be used}.

Alter booting you will be requested to press Reset until
the screen corner appears red. After this, pressing any key
will bring up the main menu. At this point, pressing the
space bar selects the keyboard as the main input device,
while pressing the joystick fifebulton selects the joystick
as the main input device. Once selected, the in pin device
may be changed while on any menu succu by pressing
either the space bar or the joystick lircbutton,

Unce the mam mem; has appeared you see eight possible
choices:

Ulxl print VA page)

2) 2 * 2 pilot page)

3) 3 x 3 print {full page)

4) Label print
M Card Shop
fij Poster

7} Special Effects

8] Disk Access
Fat h selection is represented by a picture on the screen.
Your choice is made by placing a movable square around
the picture representing the desired option and pressing
the fire button {I selected the joystick as my input device
for this, review).

The first three main menu options produce identical
submenu;. You may I ) return to main menu; 2) look at
the screen; 3) change PMOOE; 4) select color or black-and-
white print, 5) choose a pt»itive print, 6) choose a negative
print Since multiple printer dots are required in provide
shades of gray for color prints, the color option is not
functional on a I a I print.

The Special Effects option lets you define two shades
of gray . rotate your print, choose only a portion of a picture
lo print by using u variable window, change the size of
a pi*d in the V and/m y direction, adjust the space
between pixels, make the space between pixel* either black
or while, and produce mirror images, If all this doesn't
impress you, nothing wilL These features make HARD-
COPY a very versatile printer utility.

The Label print option has all the features of the first
Mirer uptiunv The "color or B & W feature has been
icplaccd with a U H of labels'* feature Once a print type
is selected, a label Size window appears ovei the picture
J or you to select which portion of I be picture to pri nt on
the label.

The Card Shop option let* you take a picture, add text
above or below it (you choose the text size), create text
for the inside of the card and print all of t hk on one sheet
of paper in such a fashion w as lo be able to fold I he
sheet into a greeting i:ard\ cnrupleie with yrrni picture and
test,

The Poster option allows you to take a picture, or part
of a picture, and enlarge it into a poster. It is mode of
several 8^ by I J-ioch pages and must be put together to
form a cumplcte picture. You may choose your own scale
factor A word of cauhiiii »* in urder berec A large scale
factor produces many output pages. This may overheat
your printer heed, so it is beat to consult your printer
manual before printing posters.

Last but not least is the Disk Access option. Naturally,
this allows you to load the picture you wish to work with,
You may also view a directory or view each pie tyre on
the disk one ai a Time,

For those who would like tu pjini pielures from vuur
own BASIC routines, HARDCOPY provides a "ustrcair
i tie and complete instructions lor passing all required
parameters through the BASIC routine to the uscrcall
routine.

HA RDCOPY Is an excellent product thai gives excellent
rrxitlis Tf you're looking for a printer utility, it is a five-
star choice.

Color Computer Machine
Monitor Gets The Jab Done

Scnouj programming in as-icmbly language requires a
good editor/ assembler, a monitor, possibly a disassembler
and other software devices. Minor patching or debugging
nf" assembler programs requires only a monitor, which is
a machine Language program to observe (or "monk or")
change* in RAM caused by the assembler program one
is debugging.

The standard for assembler-support software program*
is Kiidto Shade s Lli'IASM* because not only is it easily
available and low in price, but it is the most frequently
used assembler for CoCo ML programs. Considering that
a monitor program represents only a portion of the
F.DTASM+ package, this implies that h monitor program,
to be competitive, must sell for about 40 percent of the
EOT ASM* price and ought to be more user friendly; ft CIS
Color Computer Machine Monitor for L'CMM tor short)
easily meets these requirements.

What must one have in a monitor? To begin with, its
piiniHiy purpose is lu observe the contenu of both RAM
and the CPU registers a* ilie value* vhiv during prugiMm
operation. The monitor mutt be capable of ronvenienrly
inserting break points into the ML program being
debugged, and displaying the values of memory and
registers when these break points are encountered.

The ability to remove the break points is as import an I
ax I lie ahilily m set ihem. One must be able to begin
execution at any location (to simulate unusual tut lies or
unexpected branching) and also limit execution to a ihort
enough series of commands f or the user to understand what
happened. In addition, the ability to list the data to a primer
must be present.

A good monitor must also include a FILL command.
This is used Ui load large pieces of memory with a user-
defiued hcAadcLiJiiiil value wliose change wilt br rc tidily
apparent. A COPY or MOVE command mast be available
<i> relocate subroutines. All ol the commands should ideally
ba single keystroke and the monitor must be written in
relocatable code so it can be loaded where it will not

interfere with lha program being debugged, Other features
are nicr T but these mentioned are the "bare bones" monitor
icqurremeni*. RCTs CCXfM Includes all these monitor
nplinn*

ideally, the monitor should he small (so as lu Leave a
lot of memory (or the programs being worked on) and
be self protective. KCl's mom lor comes in two version *
in one package and is small enough that it might even
work in the older 4K models. The documentation is not
too dear on whether 4K operation is feasible, but thjs
program will work properly in 16K models that do not
have Extended Color basic That puim may be very
important lo some users,

Unfortunately, the RCl monitor got poor marks From
me on self-protection; I could crash it quite easily and
ii usually required .1 cold start {with loss at ihe program
under development) to get going again. In addition, the
keyboard sensitivity willi CCMM running changes, which
made me Uncomfortable. The docunienlatiun, while neatly
printed, conveniently arranged and cotn|iieheusive T is
unintelligible. (I'm an Mi l engineer and 25-year computer
uit?r. and I often could not understand this author.)

1 must give RCXs effort only a second place rating. Still,
what is user friendly to me may be the opposite to you,
and Color Computer Marhitif \f<tniivr may be well-suited

lor your particular assembly rawrto

OS-9 Hi-Res Screen Dump
Utitilim For Quality Printouts

Tandy has released a new product in I he line, a
Hi -Res screen dump package called OS-V Hi- Res Screen
Dump UttiUles. The program* come neatly packaged in
a 7 by I f -inch book- like container including the instruction
biHlklcl, prngrnm diskette And Software reghirnlii.111
int'ormdiii/n. This information will allow the owner lo
receive updates to the programs. Enclosed with the
registration card is a software version log lo help avoid
any confusion with later patches or problems.

QS-9 Hi- Res Screen Dump Untttm comet in two
versions, both requiring 64 K One for Tandy (or
compatible) dot inairi* printers and ihe other for ihc ink-
jet pijutei and its col 01 capability. These pfogiatm will
allow the user several options, the first ol which is 10 print
whatever ts on the graphic* screen to the primer, "I his mode
hus several options I will discuss later.

It is also possible to prim a picture file 10 the primer.
The third tnou> "tie I found rather interesting. It will
Allow l tin graphics \cxtrn or pin lire filr to he vnl lo disk
This is not so great in itself, but all it tales to print the
tile hater is to LIST <j3athnnm H > >*'p. Why is this so
great you ask? If the picture has been dumped to the disk

in this manner, it will he much easier to make multiple

printouts of it,

Each of the programs has its own m of option* to pillow
the user to customize the dump. The black-and-white
program has three options: T, *C" und "?\ Very simply,
these stand for Inverse (swap black and white h Condensed
dud I P VJI(7) mode If the LP VII or DM P* 100 is used,
the *T option must he used lo aceiimtnuJate those printers.
AJso f the Condensed mode will not wtirfe on cither of these
two printers.

The color dump program has 10 different options, each
specifying a different color set. The First six del ermine which
set of lour colors are to be used and the tost lour ore
for sening the two-color modes. When using the two-color
mode*, the hari/uninl resolution is 256; the four-color
modes each have a hot isumal resolution of 128. The iwo-
color modes consist of combinations of bl-n k. white and
green, while each ol the tour-color modes consist of
combinations of the colors available in Extended Color
HAMC«

These utility programs are very well-packaged, suffi-
ciently documented and extremely easy to me. The disk
is not in any way pt nice ted which allow* cn^y backups
for archival purposes. One thing 1 would like to have seen
in the documentation is a procedure that could be used
10 save a section of graphics memory to a picture file.

A drawback to these programs is that if the user has
the H\~Res(0+PAK) program installed and calls up either
of (he programs to dump 1 hat screen, the screen is cleared
and the programs logo is printed on the screen This icsuIk
in loss of the information on the Tii-Res screen and punt
out ot the screen dump program's banner — a major
problem. The only way around that is to save the screen
to disk and then print ii in (hat manner which once again
demonstrates the need for a discussion of saving graphics
MJtecm to disk.

If you use the Hi-Res graphics capabilities of OS-9 und
wish to have a printout of your Hi-Res sciecuv I wiruld
highly recommend this package to you.

The Letter Box
Printer Buffer
Part 1

/// Dermis Kitsz's premier article, he begins the first
in a series on a vast -efficient way to build a printer
buffer.

By Dennis Kites
Rainbow Contributing Editor

Quirk I Rni*c yttuj hand if you've
heard of a 6805! No. \t\ not the
microprocessor in the MC-tty
ithjis 1 , ll OKU.ii ) I he 6UUJ c, u
close cousin, a microcomputer on a
chip. It's the heart of a 64 K printer
buffer - ■ I call it 'The Letter flux"* —
for your Color Computer,

This, is the firm part nf a series on
huikUni: j primer bulla. I'll tinker
these questions: What is a buffer? Why
do you need one? Why use a micro-
processor for just one job? What makes
the tiKUJ microprocessor a goud chuicr
fur this job? Can tile buffei perform
i filler useful functions' 1

This project has been a Long time m
speculation. My Inends often say*
"You've been talking about a printer
buffer for months. When will il be
done? 4- l\e rold ihem + "1 warn ii entrap,
cheap, cheap' If I wauled il cipeiiuvt:,

What is a Buffer?

Shortly after using a computer

(Dennis Btsthuty Kitii is a lompt.wer,
snff*itr« 'author and an electronic
designer : if is computer career began in
19?? after paying his dues as a librarian,
truck driver and graphics designer, t

compared to the computer* themselves
- printers are alow mechanical devices,

seem to take forever to print a program

World Scries and do two loads of wash

quality doisv wheels, such as t>!r,at
oi brother, to prim j lomi article.

A printer buffer acts as an electronic
waiting room, it's a place for informa-
ihm to mi aft ci lhc corn p liter semis il
to be printed, and before the printer
is able lo look at it.

Most printers have some kind of
run |1 in n union buffer, but it seldom
holds more than one line {256 charac-
ters). Newer uniis offer buffers of 1,024
in. 4.n% cliaiHCters, tin I even these fill
up idpidly.

Some sophisticated Color Computer
setups with disk drive ^ and high-level
operating tiyst ems have so called virtual
buffers, also known as spoolers,
reserved on several disk tracks. The
ope rating syvtcnt fuok tbe computer
into "printing" to Lhc disk {spooling).
The operating system later extracts the
information trum the disk whenever the
printer needs more to print (dcspool-

itig) r {A box of burnt resistors lo the
first person who can recoil the origin
of the term "spool." Hint: It's an
acronym.}

Those of us without the pleasure of
an expanded disk system and tiny
buffers in out printers need something
else. The Letter Bo k is a smart buffer
thai holds a whopping 63.232 charac-
ters, and plugs into the computer's
printer jack- Best of aJ) t you can burld
The Letter Box for under SI 00.

Why j Microprocessor?

A printer buffer appears to be a
simple thing. You transmit a series ol
characters, it receives and stores them,
and transmits them to the printer when
necessary So. why use a microproces-
sor? Partly Hi reduce the amount of
hardware, but, belter yet, for hells and
whistles!

With n microprocessor tMHU) in
control, you can program the buffer to
act "smart" and do other things: print
a test routine of all the primer's
dim Holers; *lup for not) after u dcsig-
ruiTerl number nf lett lines,; stop (or not )
after every form feed: atop (or not) after
two carriage returns (a paragraph):

My goal in designing The Letter Bos
was to stuff the greatest number of
iVrtinit-s iruo ilitr MimllrM number of
parts for the least amount of dollar*.
With 64K DRAM (Dynamic Random-
Access Memory) prices spiraling
downward, these chips were the logical
choice for a large buffer. Even cheaper
(free I) are 16K DRAMt pulled out of
Point Computer 7\ lhai have been
upgraded to 64 K

The butler's o perilling system would
have to be in some kind oi LPKOM
(Erasable, Programmable, Read-Only
Memory), and some "cjue chips'* would
be needed, f Glue chip is a clever "tcchte"
term fur I lime mlscdlmieou*, integrated
circuits that keep a computer's proces-
sor* memory and input /output all held
together.)

The biggest obstacle in building a
cheap buffer is finding an inexpensive
technique to perform serial input and

least until I took a good look at the
680 I / 6803 microprocessor family. I got
the hint by tinkering with Radio
Shack's Micro Color Computer, the
Mf-in, which con I a ins. a (tROIF rmcrn-
proccssor. Although the MC-10 was a
market ine flop* 1 had always been
impressed by its speed, features and the
number of commands and options that
bad been crammed into its MicrccoJor
hamc operating system.

But what really caught my attention
wa* the ftftflVs hni ll-in serial input/
output system. Depending on the choice
ol crystal frequency and the sequence
ot internal commands, the 6b*0_< can be
made lo transmit and receive serial data
at 150, 300, 600 J 200, 4*00,9600, 38400
and 76800 Baud.

Since the nROI ensi less than $10, my
solution seemed at hand — almost.
Some questions remained; Could the
6&03 switch between Bauds {say,
between 600 and 4800) "tin the fly "7
Could the 6803 be set up lo perform
the memory refresh necessary for
DRAMs? If it could refresh PR AMv
would the number of glue chips grow
too complex and expensive? And.
finally, could u parallel printer port be
squeezed into the design with no
additional parts?

A Closer Look

To answer these questions, a closer
look at the b8U3 is needed. Among other
connections, the 6803 has pins for Vcc
1*5 volt power?, Vm (ground), Xtal and
Extal (crystal or master clock inputs),
"E* tenable signal used to synchro iii/e
with memory w peripheral*, uuc-
qu ortcr the master clock frequency )*
NMl (Non-Maskablc Interrupt}, I HQ
I Interrupt Request) and RES t reset)*
We'll describe how all of these are used
during the theory and construction pari
of this series.

One of the WWW* attractive feature*
b that it has two input/ output ports,
Port I is a complete eight-bit parallel
port (maybe for that parallel printer
option?); Port 2 is a specialized five-
bit port. It can be used as an ordinary
parallel port, hul ii also usable as a

timer and as an SCI (Serial Commun-
ications Interface). The SCI is the key
to the functioning of The Letter Box,

The 6803 also has an Internal 12S-
byte RAM. With its option Tor battery
buck up, this RAM L-an be very handy
for lah or industrial control This
project won't use the backup feature,
however.

The 6803 has the usual address lines
JS through 15. An important consider-

a I ion in lining the 6803 is the multi-
plexed dniav low-add tes* ban. Because
the number of external connection* is
limited to 40 pins, the designer* had
to soueezc the eight data lines tD0-D7)
and eight low-address lines I AO A7}
onro the same connections. The AS
signal (Address Strobe) Is used to let
thedo uit tunw when | he addre.v* lines
are changing to data lines.

The whole proccsn of multiplexing
and de-mulliptefcmj; is ai firsi a mys
lerious one, and there are two major
instance* of it in t hi* project; with the
6803 microprocessor (squeezing eight
data and eight address lines logo her),
and with the dynamic memory (<rp tree-
ing lb udd rcs> 1 1 iil- > onto eight pinsK
More about that later.

How Do You Start?

This project imnlw* building ;i
computer. How do you even start
thinking about that? It's overwhelming.

Some of the thinking is done simply
by acknowledging what you need to do
— have cheap memory, a serial inter
face, a simple operating system, low
parts count and low cost. And part ol
lluit work is ilune Jiiiure I he type uf
memory (64 K DRAMs) and the micro-
processor 16X03) have been chosen to
fill the essential needs* Mow what?

What about, memory refresh? What
is ii, and how is it accomplished? By
now youVe probably heard the analogy
1 1 mi dyriauiii: Eiicminy is liken tile wiih
a slow leak — it needs a hurst of air
every so oltcn to keep it inflated. 11k
technical characteristics of this kind ot
memory are such that 256 contiguous
memory locations have to be read or
pulsed ai least every I / 500th of a second

ACCESSIBLE APPLICATIONS

Using A Spreadsheet
As A File Manager

By Richard A. White
Rainbow Cuulri billing Editor

Ah! You noticed lite new liflr for
the column* After a few week*
of discussion around THE RAIN-
BOW offices, "Accessible Applications"
surfaced. 1 rather like ii for what it
communicates in two words. The power
wl' ilif cMiiipni^r should be accessible
to the user. I think ihm means easy iu
use.

How cosy? tasy enough to start
simply and do something worthwhile,
then, step by step, team the Harder
task*, The second requirement is that
it he fairly easy to remember how to
use the application. Spiradsheeis
typically meel these reqiiir^mrnK
Other applications dont necessarily,

A powerful file program may Let you
define simple record structures, enter
duta, save ii. reload it and review it,
Wlien it come* lu printing that data in
a nicely formatted report , the new user
runs into a wall in the learning curve
There is a lot of complexity in describ-
ing to a computer just what is wanted.

berg, he is the author of the TIMS
database management program.)

Spiewhheets tame off well in the
printing area, since "What You See Is
What You Get" — WYSIWYG fot
short. As lone as your work bobs good
on the screen, Lt should look good
printed.

On the other hand, learning the
complexities of one of the CoCo file
programs can he a lot simpler than
trying to write a piogiuui in rash in
do the same thing.

There are differences between pro-
grams of the same type, too, A fairly
simple file manager like TfMS tf very
easy I a use fur small databases, but it
wilt not open Trior disk fdet and draw
selected data Out of each to generate
a report, hor this you need something
like EUte*Fdc, which has some horse-
power, and you need to figure out how
io use it.

The word processor, even a simple
one, can vastly increase one's produc-
tivity. Frankly, I would not even icy
to write this column without a word
processor. t here never was any love Lost
between me and the typewriter.

And, we are dealing with applies
i i< i ok. These are computer tools to gel
work done. 1 have named three types.
They handle the bulk of the work I hat

is done on computers, but there are
others: accounting software, telecom-
mimicaiion*, inventory management,
ordering, shipping, hi! liny Jim! <m on
There arc separate softwaie pack Hge*
for each of these applications. Some,
however, can be done with a spread-
sheet or a file manager. Indeed, a
spreadsheet or file manager does:
unfiling imi.il the user programs an
application into it. Tinny can he con-
sidered a higher order language io ilu-ir
own rrght whose purpose is to help the
user access the computer,

rainbow Managing: Editor Jim Reed
tried ihe loan payment template in my
June column and immediately found
.some problems with iwo equations. In
one case, the leiler 'H' had been
substituted tor an up arrow and the
following open parenthesis had been
dropped, In the other ease, the up arrow
was again dropped and the letter "C"
which immediately followed had been
prio led in lowercase. It smells Like a
machine problem. In mew heir, vnntc
sol t ware is thinking the up arrow is
signaling that a control code is follow-
ing and we are on that trail.

A question that Jim had was how
did I replicate the part that calculates

238

lHfcrtfliNeQW ucioftpr r«ft5

the individual loan payments for each
month the loan is outstanding* To
rclrcsh mcunfinps, a portion of ihe
spreadsheet showing only two months
is shown in Figure I.

The objective was to copy the A 14
- - * DI6 down the spreadsheet starting

in fell A 17 Elite* Cafe simply lets you
copy the range in A IT You nerd lo
tell Eiitt whethei oi nul lo dntiige llir

rate, and B\ the payment per month,
are referenced for each month's caku
I ai i on they s hoy Id not be changed T while
all I he others must be. Ncxl. you copy
iwo mnnlW worth a* a limn, ihrn four,
etc.

Life is not so simple with DynaCaic
or VIP Cale> They provide only a
replicate function that allows you to
replicate one eel] to a row or column
of i < Its That's not what we want.
Rcplkatc can also copy a row of cell*
lo other rows H That's closer, and we will
have to settle i or thai in some way.

In Viy Utk you would replicate
range A14 < . < DM to A 17. Next
replicate AI5 ... DI5 to All? and
finally A In DI6 10 AI9. That
handle* one month. Repeal (he process
till you have replicated all 1 l>c u ion elm
you need. Jim couldn't unite imagine
me doing: that for a range ol 36 months.

] can't imagine doing that either, hut
he caught me cold months after 1 made
I he spreadsheet and ) could not imme-
diately remember how 1 did do it. Thr
answer is a command in hyrmCnk
colled "Kcysaver." Properly used, it is
better called "Lifesaver.**

[ try to deal mainly with functions
that are common to mod of the CoCo
s(iirrukli?el!> There are times like this
where rules niu&i be broken. Many
DynaColc owners need to underhand
it,

Simply stated, Dynatale remembers
all the keys you press after pressing the
BREAk key. There is probably a limit „
htu I haven 1 ! reached it yet. After you
have Li) molded a seiicv of command
keystrokes, press */ * and 'K". DytutC air
asks "times? 1 ' Type a number and press
ENTER. DynaCalc then perform* the

saved keystrokes in the exact scries the
number of limes you specify.

How does this help? Say 1 were to
replicate range AM . . . DM to AH
and then moved the cursor to cell AIT.
If T had preued BREAK just before
starting the keystroke sequence, I could

now enter Kl. DynaCaic would start
at AIT (that's where the cursor was),
tall Replicate, define the start range,
A|7 r , . D!T. define (he larget cell, A20 t
respond to t he Same-Relative quesi ions
for each equation and move down to
cell A20 at the end. Wow!

But, 1 needed more than one more
replication; 1 needed 33 « So I used 'K33
and vat bac-L to wateh the screen dance.
Ranges A15 . D15 and A16 . . Dl6
were, handled the same way and the
whole spreadsheet was done over a
pehod of several minutes. Other Key-
saver uses include inserting or deleting,
bunches of rows or columns. You could
change the format on all the cells in
a row or column without disturbing the
data or equations in the eelk

Keysaver isn't perfect. I have had
infrequent problems with arrow key
movements, but arrow key movements
at the end of a keystroke sequence seems
to work all right.

Moving onto! he title topic, a spread-
sheet makes a simple but effective file
manager, so let's discuss some basic
concepts of file management, A file is
a collection of records. This brings to
mind phonograph records, and you
rnjght havu qui te a few. You could make
a file of the tides of all the albums
Widen Column A to 20 or 25 characters
and type in the names into cells down
the column,

OK, they are out of any logical order
so there needs to be some sorting out.
Spreadsheets sort by exchanging
column* or inws. Fveryfhing in (he row
or column is swapped with the next,
t his is not a mindless swapping — the
spreadsheet looks within a range you
give it and does the sorting according
to the contents of the cells in the range.
Ai i his puini, to sort the album file,
you would use a range in Column A
to include all I tic titles* The suit

Function works from the left- most
character in each name com pn ring
characters wil]i the next uuint tin III a
mismatch is found, A swap occur*
according to fixed rules.

First porting can arrange the record:?
in ascendiist ordvr. nhcre thr -,:riailesi
is first, or in descending order, where
the smallest it last OK for number*,
but which is smaller. 'A' or *B^

characters you can type from the
keyboard, and then some, are shown
with a number aviignrtl lo cm U Hint
number is the ASCII value and ii's that
number that CoCo uses to decide iT 'A'
is larger than 'B\ A\ ASCII value is
66 while B's is 67. so the computer
i hink-s B*is bigger and you jrcn'i goiqp
tu change its mind.

Let's check out the tats in A$Ctl\

computer books on my shelf sorted in
ascending order.

A record with a leading space always
sorts to I he rnp of an ascending sort.
You may not notice the spate and
wonder how a record got so out of
order. ThntTs how Programming the
ZSO got to t he top.

Numbers have lower ASCII values
I ban letters so 1-2-3 A to Z h just where
it sliuuid he. By i he way, The order of
numbers ts 0 1 234S67h<J If you enter
dates like 7/4/85 and ID/ 12/85. month
10 will sort before month 7, This is why
you see computer- produced dates 1 1 ke
07/04/85. The leading "0" sorts ahead
of *r and puts July before October.

Finally, lowercase letters sort after all
Uppercase letters. There are some
punctuation and special characters
before the numerals and some after, hut
all son before the alphabet.

The album file only contains the
names of the albums. These are only
in Column A, F_ach row is a record and
each has only s>ite field in use, the
Column A cells. Lcfs call Column A
the NAME field,

There is other data that is associated
with each album sucli as performers.

A column could be devoted to each of
these data types with the particular data
entered in the proper column in the row

each row is a record that now would
have a number of Heidi of data. You
have done this sort of Usl mi papei
before, but you were probably nut
i hi n king in terms of records and fields
when you did.

Now you j sorting options become
broader and you can do a number of
mii k i hi the file First, lei's son the
whole file by type of music Call the
sort again and give the range for the
column containing the music type data
and include ail the rows in use.

With that sort mode, you might want
the hard rock-type music sorted by
perform? i. All haul rock albums should
now be in one group in the spreadsheet.
Stat using the performer column, hut
limit the range to only those rows that
include the hard rock entries, Vou could
hate sorted bird rock b> utk- oi even
year uf publication as well

Which way ittnulsl the file be stored,
on tape or disk? It's something m think
about. It you have spent some time
making multiple sorts, think about
storing the file that way. You can always
load it and resort it if it needs to be
arranged differently for a specific
purpose, Vou can even s;ivr it sorted
in a number of way* 1m different
separate hies, but keep in mind that
when updating time comes, you will
have to update multiple tiles.

Don't forget the columns; they can
be sorted as well without jeopardizing
the ifilrgiby of ihe iofnrmalion in a
record. The fields will just be in a
didcrcnt order in a record.

DymCaic has a Locate Label I unc-
tion called by >L. DynaC ate then asks
for a string to search for. This string
is just a sequence of characters and need
out he a full \v\ Ic ur name. Using my
book list, I might search for r and get
lour books reported, tf I gave the
program C. only, The C Programming
language would be found, J his pro-
vides a fairly powerful and useful search
capability Even the famous Lows f-
2-1 on an TRM PC cannot do this so
easily.

Hut. the starch supcfstai lias lu Ik:

ysiu cart find values, labels or the result
of a formula. You can mask a string

search so t'JP Cate will ignore cose. Vou
can even have wild card character* if
you don't quite know the right spelling.
This combined with VIP's large data
huffier makes the program a good
candidate if you have some spreadsheet
file work and would prefer to learn just
one program.

you can print a file, For example,
matting labels are out With the whole
record on one line. You could save the
records out to disk as an ASCU file
and use a basic program to read and
rearrange each record 1 then print it to
a mailing label. If you arc only going
to pnnt the list one way, the task is
not particularly hard it you know
BASIC. If, however, you arc a user and
not a programmer, it's another matter.

You can son the eolumns or move
thr mhirrhiis 10 get a number of fields
adjacent and print those fields and nut
others. Say you were selecting music
to piny on some program and wanted
to use playing time as on important
selection criteria. Sort the file on the
p laying-rime column, then group the
name, performer and playing-time
fields next to each other ami print these

Niw (Graphics Drivers
Announced at NCC

The really big news from Des Moines
came in a joint announcement from
Micro warr T Hilachi and Graphic; Soft-
ware Systems. The three firms joined
forces to develop a complete set of
graphics support modules Eur Hitachi's
new ACRTC device the HD63dg4.
The new drivers conform to the pro-
posed ANSI/ ISO Virtual Device Inter-
face (VDI) s lamia id and give n>flwarc
developers a way to write portable
graphics-oriented applications soft-

ware, The standard itself was selected
by both IBM and AT&T as the de facto
standard graphics development envi-
ronment for PCs, Now, it's available
on OS-9.

""We have achieved an incredible level
of integration of all the hardware and
software pieces tmUtM needs to build
a state of- the -art graphics system / said
Ken Kaplan* president of Micro ware
Systems Corporation, " Hitachi and
Micros re tun now offer a total
solution to manufacturers of personal
com put crs. C AD i C A M systems, graph
ics work stations and similar products.*

The drivers let programmers mix
graphics Images with text data dis-
played in mulliple font*. The software
itself can be developed! using Micro-
ware's C compiler running on a 68000-
bnscd development system or a Large
DEC VAX lime sharing system. BASIC.
PASCAL and assembler programming
languages with graphics capabilities are
also available.

processors, It operate lll a clock speed
of 10 megahertz, draws at a 4QQ nano-
second per dot rale and creates images
of up to 4.096-by-4.096 pixels. The
hardware itself can draw dob, tines,
rectangle*, polylines, polygon, circles

(iood Reviews

I've heard good comments about
several of the programs weVe highlight-
ed in this column during the summer
Otmrge Horner, OS-9 Users Group
treasurer, reports in Issot Number
night of MOTD. that XCum9 - OS*
*Vs first ^trccWBrc" program — is a real
bargain.

*'XCam9 > & major advantage is its
XMODEM protocol for uploading and
downloading file*,'* Domcr said.
"Other notable featinc* include nil
ASCII mode which strips panty. rahs
and other bothersome eharuetcrs. Vou
have complete control over most of the
program? parameters and can even
send a break with the 6830 A CIA."

Domei also had many good things
to say about Steve Odncal s Kama* City
BASIC for OS-9. Odncal was one of
the first programmers to bring the
FLEX operating system to the Color

Barbara liny BASIC, whteh wai
published in Dr. Dobbs' journal several
years ago, and added many enhance-
ments Quoting Domcr, "KCB looks a

Bruce A. Williamson had a similar
problem and came up with yet another
solution, a BAS1CQ9 program, We'll also
share it here,

Bruce owned 8EMrack drives and
wanted Llue option of using either /dO
or ,'dl while he was compiling hit r
programs, [lis solution was a "brute
force" das ices program named erj. In
his words. "It may not be the best
example of programming or

may not suit everyone's needs, but it
is very easy to modify. One possibility
I've already considered is in add admin
command at the end to chain to the
.lw?i lilc,"

Bruce s program requires thai
CPREP be patched and renamed
D.PREP. He shows you how to do it
in i he listing named cDiff. Although he
would not have had to rename his LIB
and DEFS directories, he did sn
because he did not want to merge
directories on du. If you do not rename
your directories, you will need to
change ibe appropriate lines in the
program and patch CPREP (see
Listing named t Oiffi. He is ptrsently
rewriting ccJ in C and plans lo make
it available in an OS-9 database.

Three Prime Number Pro crams
without GOTO*

We pcally woke up (he sleeping giant
when we published Hie challcngr ui
rewrite the prime -number generating
program without line numbers. This
month, well show you several versions

and share some of the dialog we

received,

Our lirsl listing was submitted by
Kevin Cant well, of the Washington
State Department of Licensing. Kevin
has a degree in mathematics, lives in
Olympia* Wash., and has worked as a
programmer foi both I lie United Slates
Air Force and the National Oceanic and
Atmospheric Administration. He writes:

*T changed some of the logic to
correspond lo the apparent design
attempt of the program . , , since for
i he version printed (he l XXXX is a
prime number!' message and ihe last
prime divisor would not be pinned. Hie
listing. fnmesJ, corrects this problem
and eliminates all GO IDs. It is a bit
elower and takes just under three
minutes to discover that 44440 is a
prime number.

"It may he wonhuhile lo point out
thai the real use of the Prime* and
Primes? programs arc lo find the prime
divisors of a number, rather than to lind
primes, lf you simply need to find out
whether a number is a prime, the second
p/ogram, QPn'mez t will check it much

taster. This pmgiani economizes in iwu
ways: It stops when the first divisor is
iound, and it makes u*e of the fact thai
a composite or non-prime — number
must have one divisor smaller than the
number's square root."

Our next challenger was Steve Gold-
berg of Beth page, N.V, He gut rid of
the GOTQs in the original listing by
using the WHILE . . . END WHILE,

the eight-digit number, 1 2345678,

recursions from Sherman's Procedure
Prime. They were not needed and
merely used up memory."

Greg Law sent us a note with a tip
for people attempting to install a patch
thm leis you use the Q%-9 DCheck
utility with a hard disk The patch it
one of a group written by Sandy Trevor
and stored in a file named II A R D.PAT
ia One Of the OS 9 S|G s databases, Jt
seems the patches for DCheck are for
OS -9 Version 1.00.00, Here arc the
off st is for Version 1 01.00,

Essentially, the patch changes thc*D'
in /DO to un H and makes it read
J HO, Then, it corrects the CRC bytes
in the file so OS-9 can load and execute
it

Uhk Traiufer Program

I havens heard from D T P. Johnson

what lVc been readings the ttitihur of
SDISK is Maying busy. He ha* a new
package named PC- ,Y FER available
7655 S.W. Cedarcresl St., Port-
land, OR m-2M-% 1 52J that you
will find handy if you work wuh an
1RM or v.\ww Hi the office and need
l o carry leu filrs hnmr in your Color
Computer

Johnson's PC Head uiiiity can read
a file from an IBM PC single-sided disk
of up to 40 tracks. The only restriction
h the file you are copying off the IBM
dialf must be in the ruul directory.
Conversely, his PCWtitr utility wnirv
u file into the root directory of an IBM
disk so you can carry work you did at
home back to the office.

The PCFormm utility will format a
standard IBM single-sided disk, PCDt-
fctp will delete a file from an IBM disk.
Iti addition to the IBM unique utilities,
Johnson's PC-XFER package gives you
utilities that read and write data from
Or to a standard 35 track Radio Shack

catalog rjumbcr of the ioflware voj arc
registering and the version number
ulready prc-ttamped on I he cards. Big
companies usually know how to save
lime, looJ

As it happened, this particular r»r<t
didn't have the Catalog Number
stamped on the card. In my haste to
slap on the stick-on label and get the
c>«d in the mail, I didn't notice the
missing num I ir j As h result,, 1 got a
nice kltcr from Norma Alexander Ut
the Sot i ware Registration Dcpartmem
at Tandy, She explained how to register
software when yon lose the registration
card or it is missing from your manual.
I i hough i 1 should share the three
methods with you. Ttiry sire:

1 ) Send d copy of t he i eveij it *l mw i rig
the original purchase with the
stock number indicated.

2) Send the oriainal titJt page Irom
i be toft ware manual. It will be
i ecu rued lo you.

\} AsJr for written verification at the
store where you purchased t he
item.

Be sure to include the stock number
and version number for each item you
arc registering. If you have any prob-
lems vi questions about software
registration t you may write Norma in
care of the Software Registration De-
partment. P.O. Box 2910, Fort Worth,

Next Month — A DynaCaic Tutorial

In the Nnvemher issue we hope to
present & tutorial on DytmCatc We've
been talking about the need foi appli-
Csiii'm programs Jong enough — it's
time lo show off an excellent one. Joe
Turner at Computer Systems Center in
Chesterfield, Mb., has given us a few
tips and \y letting use some sample
spreadsheets available tn the SS-50
crowd but not the Co Co owner.

Well list several procedure files thai
extend the width of ihe original CoCo
OS-0 D1R and M DIR utilities, The
pi of ed ure files show how you Can
actually accnmplisii some program-
ming task* with the powerful OS-9
utility command set — right from the
operating system command prompt.
They were contributed by Donald L
MeGarry of Northport, N.Y. Well also
give you our first reaction lo three new
piogfams — the OS '9 CBitg Debugger,
the OS-9 Ttxi Formatter and (he OS*
9 Macro Assembler — that just arrived
from Compute rwarc in Cncinttas, Calif.
Till then, happy hacking! ^
