Now I am trying lo u«r ihe ^ Tompilcr

nothing abom the mechanic nl i^inb' the

'ou will nonce a slighily new look to THE ft<\tNHGW this month One
. the changes it 10 make your reading and understanding a bit easier
In most of the article* and tutorials, you will wc the keywords and commands
thui you type into your CoCo in d different style of iypc — one that lonkn
u I mi tic the teum that actually appear on the screen.

Ttm is the evolution or a process which began in the early days of 1 rainbow
when, using a dot matrix printer, wc used etiolation mark* to make the commands
luok a Utile different. From there, still with the dot mm rix printer, we experimented
with condensed type and, finally, italic type.

Once wc got into typesetting, after our first year, we continued using italic
type; this was better because of the typeset quality. Wc continued that for some
time, always looking for tomctlung belter.

Three months ago, after a lengthy search, we took delivers- of a new typesetting
system — a digital machine with a hard disk, three terminals, imuge previewing
and other "bells and whistks.*' One of its specialties was ihe ability to use a
large number of lype styles al ihe name lime, wherea* before, we were limned
to Its ui a lime. From among these added possibilities, we chose the digital
typeface to designate ihe command* you type inio your computer

So. now, we have something new. I have always believed the caster we make
it 10 read THF RAINBOW', the better you can u*c it This b a step in that direction,
We*rc taking other ntcps, too. You wdl notice some pans of the magazine
have undergone what our an department calls a "redesign " in the past lew months.
Harhcr than make a big deal out of this, wc are just doing ft a«= we go along,
The object, of course, is to make it easier lor you to read and use THE rainbow
For example, yon will see that our assembly and hamiov listings art done on
a daisy wheel printer — because it makes them uasierto read.

Look lor more changes. And lei me know youi reaction to them, Some may
he subtle, but we ihink ihey will help in your overall ability to use 1H£ rainbow.

By the way. the change m the way we show command? on our pages will
be incorporated in our other magazines, pt m and son SK tor. as well Mention
of PCM brings me to share some UiJormnlion una major change in that pubScattafl
which might be uf interest to some of you.

Beginning with Inst month's issue PCM began coverage uf the new Vandy 1000
and Tandy 1200 computer!!, as well as (he Tandy 300 the new portable. A»
many uf you know. plm heretofore covered the Tandy 2000 and the Model
100 portable. Of course, our coverage of those two machines continues.

Actually, the 200 is fully compatible with the 100 in BASIC - ihe language
mo*l of pcm\ programs arc written in t anyway And the 1000 and 1200 -
like the 2000 are MS-DOS machines, which means much of the basic, all
of the tutorials and many of the program* wc run anyway will work on all
three machines. So, wc see this expansion as a logical step

Moreover, we see the 1000. 1 20O 3000, 100 and 200 as the "HorTandy machines
Of the latter hall of the 1980s. I personally think the 1000 is going to be a
"star" in Ihe MS-DOS market. It is a heck or a bargain lor the price* Y011
might want to check out pcm.

Over the last hall sear, I have written a couple of columns on specific subject?.
- one about the Applu Macintosh and another nbom the need of new software
for the CoCo

I said that I thought the Mac was an rnlereshng machine, but that Kkf concept
was a little rftJTu'uii 10 use for any real computing because of the necessity to
"switch"* back and forth between the mouse and the keyboard. At the lime,
though, I particularly praised the Mue Paint graphics program,

On ihe suhjret of "new* 1 software, I was miking about the need to develop
new kind 1 * of software for the CoCo, Interestingly, there rj a new product out
(or the CoCo that combines those two ideas.

EOQ Gate can help you figure all the variables to see if
you 're realty getting your money s worth

Finding The

Ultimate bargain

by Paul Myers

The following program is an example of an operational
research (also known as scientific management) technique.
Its purpose is to identify the most economic quantity for
any type of stock that is relatively steady in Hs consumption*

(Paul Myers is a programmer f analyst for Teehnican Corp, Mis nine
yearx of data processing experience include working with both targe
scale ond mini-computer systems,}

and docs noi have a short shelf life. For cxamp.c* although you
may know your family consumes five dozen egj>s a month, you
wouldn't want to buy a whole year's supply H once, even at
a bargain price: the eggs have a very short shelf life.

Again from the kitchen, here is a good example of how EOQ
Calc could be put to use. Let's say your restaur mt serves about
1 ,000 cans of corn a year, Since canned goods have a fairly long
shelf life, this program could be used to determine how many
cans should be purchased at one time in order to spend the least
amount of money annually.

The heart of the program is the following formula.

j — — All ■ Annual Usage

/ 2 * AU * OC OC = Order Cost

W HC = Stock Holding Cost

V ( HC * UC ) UC= Una Cost

The Annual Usage value represents the total amount of a
product used in one year. Unit Cost is how nuch it costs to
buy one ol the product. The Order Cost represents several costs
involved with placing an order.

If you are placing an i>rder Tor a company of some kind, there
is a cost involved with processing the paper work. The more
people who must handle this purchase order before ii is approved,
the higher this cost becomes. The Order Cost also should include
any shipping charges the order may incur.

And finally, once the order arrives at the company s facility,
someone must receive it, which usually takes uill more paper
work and handling.

\ -.in may think if we were dealing with a situation such as
a housewife doing her shopping, this cost would be nothing. Not
true! There are two basic expenses lhai come quickly to mind,
If she drives, there is an expense for the gasoline, and possibly
parking fees, Plus, while she is shopping, she cannot be doing
any other work. There is cost involved with htr valuable time.
If you were paying a maid to do it, you'd see the expenses more
easily

The last variable. Slock Holding Cost, is the catch-all for all
of those hidden expenses for storing merchandise. Some examples:

While y«w money is lied up in stock,
il can^ her earning interesi in a bank.
Thiit'* casting you money you could be
making. There is a cost involved with
keeping up a building, usually referred
to as overhead. If you didn't need in
More products, you would require less
space Thereto re > you would be able lo
gel by with a smaller building, which
would piobably cost you less money to
maintain.

Iln- sunk Holding Cosl in this
formula represents a percentage of Ihcse
upkeep costs that each product must
bear. Generally speaking, this figure
will fall somcwherv between 10 to 50
percent This would depend on what
proportion of the building is used lo
store materials*

Using the Pmprum

The following Keys are available for
your use.

Up- Arrow
Pouii-Airos*
Left-Arrow
enter Key
@ Key

Aher you have CLEJGOed the program,
type Run and press enter. A question
mark will appear in the left-hand side
of the Tie Ed where the next input will
be placed. After you have pressed the
proper numbers, pressing the FNTRR
key will accept the value and move you
to the next field.

If you make a mistake while entering
u number, press the left-arrow and it
will clear what has been typed, IT you
wish io skip up or down without
changing the value at the current
position, use the corresponding arrow
key.

When you arc ready to perforin the
calculation, press the key. The
values will remain as you selected them
after the calculation is complete. This
will allow you to experiment with
changing one Held or another without
needing to retype all of the values again.
Also. EOQ Cak will not aliow you to
calculate if any of the values are zero,

One final note about the program,
I did not wish to use the 5gR {scjtiare
root) function since it is not available
on i 4K system. For those of you who
do have a system with Extended BASIC
you may wish to replace lines 5<Hl
through 650 with

53* EO=lNT(5QfllOUJ*ia-+.5|''lQ

This should help speed up the cai*
culaiion function.

BITS AND BYTES OF BASIC

I6K

Deciphering Printer
Control Codes

A significant problem for a program author is the
variety of printers Thai may be hooked tip to a given
machine. About the only thing that's standard is
the mlcrfacc hardware. Otherwise, prir ter control codes
vary with each manufacturer'* product line sometimes they
are different for various machines from the same
manufacturer Even wor*e are those machines which need
something more than just a carriage return to print a blank
line,

Fortunately, the situation is improving as most of the
large volume printers sold over the pa*! two years have
DIP switches that ran be set to configtre the printer to
match a computer for at least printing text. (Printing
graphics is a different can of worms thai we wont get
into.)

A BASIC program still needs to have tome adaptability
to the system's printer. Ability to change the Baud rate
covers most circumstances In the Serial mode, Radio
Shack printers support either 600 Baud ar a choice of 600
or 1200 Baud.

Most other modern printers can moste isily be purchased
with a standard parallel interface and connected to ihe
CoCo with one of the serial lo parallel interfaces advertised
in RAINBOW,

Some users then run iheir CoCos at 2 MX) or 4800 Baud.
I bought a serial to parallel interface to use with my old
LP VIII and run at 9600 Baud with no trouble.

i kit hard White has a fong background with
tttit rtu nmpuien and jpeaatizts in BfiSfC program'
ming. With Don Doifberg, he ii die author of the
TIMS database management program )

By Hirhanl White
Rainbow Contributing Editor

In the CoCo. Baud rate is determined by the values in
memory locations 149 and 150. After a cold start . 149 curries
a zero while 150 is set at 87 corresponding to WW Baud
Most owners will be able to send to the printer at Ml
Baud or higher and can forget about memory location 149.
The exceptions are those running old teletype machines
at 1 1 0 Baud or less.

There is a table in the Color bask' manual which shows
What to POKE into I SO for various Baud rates. This sysierr.
isn't perfect I know of some CoCos that need a seven
in 150 instead or a six to produce an acceptable 4 tiQtt Baud
The PUKt 153,1 for 9600 Baud is pot documented in the
manual, but works for all machines 1 know of. I do a
lot of priming and the benefits of W00 Baud versus 1200
are well worth a $60 adapter,

The printer routine for the CHECKBOOK program
starts in Line 600. The first order of business is a rattier
fancy routine lo calculate the currently set Baud rate and
give the user the option to change iu

First, we assure that CoCo is running at the standard
clock speed with the pokessw Nexi , we get the value
in 150 into variable BP

The nexi operation is lo find a value thai can be divided
into 9600 to yield ihe currently set Baud rate This is done

There was a bug in the code as published in the January
KAiMtow which we will set right in ibis discussion, and
perhaps learn a Ihing at two in Ihe prneev.

One needs to be very careful in automatic file naming,
particularly jf the code is to work on both (ape and disk.

By now you*ve solved last year's
grand pri/c dinners Rescue an Alpha
II. by Steven C. Mitchell, and 77w Utt&l
a/ r/jf /km/, fry Mark NeEs-oi* (both
appeared in <>ui Dccvmhri IW nsuel
iino" taken nine ol Micsr ongiruil
approaches, along with the innovation*,
iind have a good idea ul v*liJt is required
to uincl up on top. Othci uitJiiiug
entries will be published in Hie Seam J
Raiah o w Buok of A Jvemurts . W Inch
tl m the early stages of production.

What we're looking fur m Adventure
contents arc original concept thai
appeal u> a wide audience An Adven-
ture should be challenging, ye*, hut
|boVC all it should be fun to play
Arriving al a solution thould require
only h healthy portion of plain old
common sense, not the abilits ur read
the mind of no author you've never met.

The aspect of creativity is one that
cannot be overemphasized While wc
can appreciate scenario* involving
catties and dungeons as much as the
neM person, a steady did of them would
cast the Adventure as :i fad and it would
end up in a neap in one of those I JlWO-
rooni maie*

A creative program thji comes 10
wind is Yetto* Submarine, a graphics
Adventure hy Mark Fetherston of

Kenosha. Wis. Look for it in the sec and
Adventure book because the subject
obviously has great appeal. The mere
title suggests this is one dl those
programs which could cause permaneni
damage to your knuckles in your basic
to position it in the disk drive

We're also looking for programs that
demonstrate new capabilities lor the
Color Computer. Remember the excite-
ment of loading in the first graphics
Adventure? It gave all of us n collective
sense of accomplishment 11 nd a renewed
determination m fulfilling CoCo's
incredible potential, as evidenced by the
slew of graphics entries we received m
last year's contest. We also received
some entries that required joysticks*

"IT htii tt v rr looking for
itt t fii vntore rontvMx rirp
origittitf fit net' pis . . . "

We do expect some surprises because
Co Co users have, time and again,
proven themselves Bp be an innovative
group.

Now. let's gel to the rules. Our desire
for fairness dictates ihal we establish
a uniform set of guidelines. We've
already mentioned creativity, of course,
<Ji h e 1 con side ta L ions i ncl ud e or ig i n a I i 1 y „

clarity of instructions and," or documen-
tation, ease of loading, grammar,
resolutiun, responsiveness, level ot
challenge and. most importantly,
enjoyment

Plca.se remember thai each program
must be "memors resident"; thut is, self-
contained alter being loaded into the
Color Computer for practical reasi 'rt*,
entries thai access the disk while the
program is running will not be consid-
ered Disk-accusing lends to excessive
length in programs. All entries should
r in 011 standard k ;nhn Shack computei
equipment, wnli no special inudifiea-
ttous required because of the program.

We will consider only original,
unpublished iind unmarketed proj:i .im v
One ol the primary purposes oi the
programming competition is to bring
new ideas and concepts 10 the Cof p
Conversions of existing programs,
therefore, arc not acceptable. AI&U,
entries should be self-contained and not
dependent upon other commeiciat
propram* for iheir execution.

In writing the Adventure, be cJtttful
not to pack 1 he lines so tightly Lhui we
are unable to LIST or LLIST a line II

A Night Of Horrors
In Lurkley Manor

By Richard Ramella

It's Halloween. You Ye locked in Lurkley Manor with an
assortment of bizarre people and other unearthly things. You
must use your skill and logic to escape the house without
getting humped off.

Lurkiey Manor comes wrapped in a "fiendishly" long program
listing which requires 32 K and Extended Color HASir. 1 hope
you'll find the program worth the work, for it's an all-graphics
logic puzzle with 16 scenes. 1 1 characters, animation and text
in the Extended graphics mode. You will see the instructions
when the program runs,

If your computer does not support the poke £5^5.0 "speed
poke." you must delete it from lines 2 and 1 330 of the listing,

If you wish the text to stay on the screen longer before erasing*
in Line 2630 increase the timer loop from FDR T=l to im% to
for t=i TO 2000 or greater. The title sequence and instructions
may be skipped by inserting GOTO 160: at the start of Line 120,
Do not renumber lines 1 to 64: this will cause the program to
work incorrectly.

A self-addressed, stamped envelope gets you the step-by-step
instructions for escaping Lurklev Manor, Send your request to
1493 Ml. View Ave., Chico, CA 95926.

(Richard Rametta has written mt> bwks and numerous articles on TRS-
SO topics He is a writer far a California hospital.)

Now to gel to this month's topic. One
■ ►I the rucioor> mapped ureas I described
in last month's article is the area
reserved for the cartridge ROM pack.
I also said that when you plugged in
1 he disk controller, the Disk Operating
System I Disk basic) used lhis area,
This month, we will look into expanding
Disk u\sk hardware.

To recap this area* the *CTS pin on
the controller controls the ROM chip
that contains the disk software The
*CTS select line can access a total of
,$428 bytes, i Better known as IfcKj
It is memory mapped from 49,152
ISC00O) to 65.279 <$r*>Fh

The ROM that Radio Shack uses in
Disk BASIC is on ft RK long, the lower

SK, from 49.152 (SC000) lo 57,343
($[>FFF>> AH references to the "tower
SK" will be at this address. That leaves
ihc upper SK. from 57,344 (SF.000, to
65.279 <SFFFF\. of unu&ed memory.
All references to the "upper KK" will
he this area.

Actually, ihi* memory is not unused.
It is memory mirrored 10 I he lower XK.
This means it is not properly decoded
and when ihe upper HK accesses, the
lower SK chip responds. Far cxampk-
type in:

Hoth response* will he the ^11 me.
Now. if wc were uhte lo properly decode
thw area we could use I he free space
to add another chip, usually an
FPROM Thb chip could he used as
an extension of Disk RAStf or often
used utilities.

For example, the Spectrum DOS, by
Spectrum Projects, could be hunted
into T, PRO Ms. and whenever you
turned the computer on, it would be

What L intend to da in this article
in describe the utup ib-u in (hi,- Radio
Shack c« at roller when you buy it. and
the wav You can interlace two 8K.
EPROMsoronc I6K EPROM.

TheHK EPROM I will use is the Intel
2764; it is the most economical one I
have found. The 16K EPROM is the
Intel 27I2H <a little more expensive, but
a little less trouble) ( Khe r man u fact urci*
make the same chip, but make sure it
is the Intel pinout as opposed to the
Tl pinout. You can use the TJ pinout
chip, hut you'll have tu figure oat the
piuout changes for yourself. Another
mile: If you like to use the high speed
poke, fur POKE €5455,0 you must use
si 300 ns. access time chip, or faster,
in order for it to work. The slower 450
n*. chip works in the regular mode, but
not at the faster rale.

Now. the chip that contains the Disk
Basic software i.v made by Motorola.
This chip is a masked ROM ROM
means Read Only Memory. That means
I he data con lamed in this chip can ncvci
he changed, erased or lost f unless you
burn out the ehipj. The data is perm a-
nenity printed directly on the chip itself
at the time of production. It costs less
to produce a ROM as long as the
quantity is high.

The chip used here is an

MCM68AJo4, It is an &K by S ROM
Figure I shows the pinout of this chip.
By the way T the basic and Extended
BASK chips arc also the same chip, just
different masks.

The first way of using all of the I6K
memory in the cartridge area is to use
a L6K EPROM, Figure 2 shows the
pinout of an Intel 27128 EPROM.
Examine the diagram and compare it
to Figure I.

What is Wrong with this picture?
There are 28 pins on this chip. The SK
ROM Has only 24 This is a bit of a
problem, bui certainly not unsnrrnoum-
;ibi-.- Ifs lime to get the ol h toldcring
iron and wire out. The following is a
step-by-step procedure to modify and
solder up a 27128 EPROM to fit (kind
of) into a 24 pin socket, I recommend
only those experienced in soldering
attempt this.

The first thing we must do is study
the pinout for thus chip. Examine Figure
2. the Intel 27128 chip. The first thing
we notice is thai it ha* 28 pins, fout
more lhan Ihc socket. Pin numbers L
2, 27 and 28 are the odd ones. If you
line up pin ffJ of the EPROM and pin
#1 of the ROM. the rest of the pins
are almost the same as the ROM, The
different pins between an Intel 27I2H
and an MCM6KA364 are as follows;

When it is time to insert this chip
into the 24 pin socket, lei ihc odd pins
hang out. Pin *3 on the IC will plug
into pin tfl on ihe sock el Make sure
you get pin ^ I right. It is usually marked
with a small hole or a notch.

Step 1 - Bend pins #20, #21 and
#26<on the IC) out far enough so when
you insert the chip these pins will not
enter the socket. Make Mire it does not
touch anything.

Step 2 Solder a short piece of S.10
wire from pin ff20 to pin ff22 on ihe
IC.

Step 1 — Solder another piece of #X>
wire from pin tit to pin tt2% and pin
827 on the IC.

Step 4 - Solder one end of a one-
inch piece of tt22 wire to pin 028 on

the IC. Strip % inch of insulation from
the oi her end. This end will insert into
the empty pin it 24 0 1 ihc socket.

Step 5 Solder one end of a two*

IC Strip % inch of msulalion from ihe
other end, This end will insert into the

Siep 6 Solder one end ol a one-
inch piece £i[ ff22 uire to pin ol
ihe If Strip % inch ol insulation from
the ol her end. This end will insert into
the empty pin I K of the socket.

Step 7 Solder one end of a four-
inch piece of ft Mi wire to pin 026 on
the IC Solder I he oiher end oi this wire
to pin #37 on ihe edge connector, lite
side that plugs into Ihe computer Thai
is the second to last pin closest to you
on iop n on the nghl-hand side if you
are loo king at ihe fronl of the controller.

That's it! Carefully insert the chip
into the socket making sure there .ire
no shorts. Yoo now have a I6K
I- PROM in your controller II yiniwijrii
to erase this FPRQM, just remove all
of ihe solder spots and start over agum,
LI you do a good job in soldering and
de-sold e hog. ihe fcPRUM could stand
about 10 or so recyclings*.

If you don 'i want to use a loK
FpROM. or your present programmer
cannoi handle I (SIC chips, then using
two Hit F PRO Ms is the answer 1 here
ate two problems with using two UK
EPRQMs, The linti problem is how In
decode the two separate chip select lines
and the last address line. Figure _1 shows
the pinout of an Intel 2764.

Notice thai pin #27 is the pin used
in the programming of this chip,
Htnvrvct T il thiv pin is lou' durinjta read
cycle, the chip "deselects M — the chip
does not respond to a read. It stays
deselect all the time this pin is low, If
wc were to attach the last address line
to it (A l3l when ibis line was low, the
chip would not activate. The fact thai
A 13 is low means you are accessing the
lowef SK block. Since the chip deac-
tivates when it is low h it mceis the
decoding needs of the upper block.

On the other hand, pin &20 of the

is made to activate the chip when low.
So, if wc tied Aii to this line, the chip
would behove opposite to the first, tl
would be deactivated when A l> is high,
This would properly decode for I he
lower KK block and deactivate for I he
upper.

Using ihiS lechnicfue would solve our
first problem, hut we still have one more
problem: Where to put the second chip?
I hive used this technique before and
most likely 111 use it again it's great,
It is called ihe "piggyback" technique.
Wc will solder the two chips on top
of each other, except A 1.1 and a tew
more, to gel it to fit in a 24 pin socket,

Before wc go any further here* I here
is a difference between an Intel 2764
and an Intel 27128; The 2764 has an
N T on pin *26, whereas the 27128 has
A I J,

The following n a stcp-hy-step
instruction on how to solder up two

2764s lo fit in a 241 pin socket and he
accessed as a 16K chip.

Step t — Program the first chip with
the data thai goes into Ihe lower Kit
and mark it as the lower chip. Program
the second with the data that goes into
the upper SK and mark thai one as the
upptt chip. Ii is unponunl not 10 get
the two mixed up, they are not wired
up the same way.

Step I — Take ihe lower chip and
bend pins #20 and #2.1. Take the upper
chip nod bend pins B2Q and #27.

Step 3 — Mount the upper chip on
top nf the lower chip so pin #1 is on
pin #t t 2 on 2, and so forth, leaving
a small gap for air circulation. Solder
all the unbent lips nf the upper chip
to the bases of the lower chip, Even
il Ihe lower pin is burnt, in the cast ol
pin 023.

Slrp 4 Solder a one-inch piece of
030 wire from pin a 20 lo pin #22 on
the upper 1C

SlepS- Solder another piece of U ]A\
wire from pin #1 of the lower IC to
pin *2Z k nil and a 26 of the lower 1C

Step 6 Solder one end of a t wo-
men piece of #22 wire to pin #2 on I he
upper K T . Strip H inch l>J insulation
from the other end- This end will insert
into the empty pin ff21 of the socket.

Step 7 Solder one end of a two-
inch piece ol #22 wire to pin #2} on
live upper K" Sinp ! . ; inch of insulation
from ihe other end. This end will insert
into the empty pin tfl* of ihe socket.

Step ft Solder yet anoi her iwo-
inch piece ol #H) wire from pin #20 of
the lower IC lo pin #27 of the upper
IC Solder one end of another four-inch
piece of wire to pin #27 of Ihe upper
IC and solder I he niher end of thai lo
pin #37 ol the edge connector. See the
first Step 7 for proper location of this
pin,

You are now ready lo plug ihe
"spider" (as I call n> into the sockcl.
Remember pin #,1 in the spider goes into
pin #1 of the socket. The other lour
pins slicking oui over ihe socket are
ffl, #2, W27 and 'OH.

By popular request, for those of you
who do not want lo build this project,
there is a board adapter available, built
and tested, that you can buy from
R.(r,S. Micro which does the same
thing. See their ad in this magazine It
fits hi side only the JAM controller and
is made for two Intel 2764 FPROMs.

CoCo Becomes

If you uwn a small business and have
any employees, then you know what
a hassle payday can be. Nov. you
can pui your CoCo to work doing your
pay roll arid allow yourself more lime
for important matie^

Here's a payroll package that's
patterned after one used by a large
American corporation. But ibis one
only requires a I6K CoCo. a disk drive
And a printer.

Payroll Package is a sophisticated set

( Dennis Weide is a iommumcathns

Payroll System Program Description
(As listed an Disk Directory)

COMPUTE BAS - Comput cs p ay roll for all employ ees. C alculates
nei and gross pay Keeps track of employee
attendance. Generates all data for alJ databases.

EMPLOYEE/HAS — Prints pay checks, pay stubs and employee
mailing list.

EMPLOYER,' BAS — Database manager for payroll database.

Allows editing of the database.
PAYROLL/ DAT — Database for all employee data. Used to

comptite pay and print paycheck*..
EMPLOYER/ DAT - Database for all employer records, Used to

compute payroll for employer

The Paymaster

By Dennis H. Weide

of four programs that should make your
business Hie easier. It shows the
usefulness of the CoCo in small business
applications- These four programs will
compute the payroll write the pay*
checks, and keep employee and employ-
er payroll records as well as alien dance
and vacation records.

It can be modi lied to analyze or print
the stored data in any format desired.
You can modify it to prim the W~2
forms Uncle Sam requires from every-
one. Table I gives a brief description
of each program and its function.

The program* arc straightforward
with no fancy gimmicks (peeks and
POKE*), so they will work on any version
of the CoCo with I6K or more and Disk
basic. The variables are listed along

with an explanation at the beginning
of each program so any experienced
programmer can easily modify them.

How it Works

On a normal weekly, bi-weekly or
monthly schedule. Load and run the
payroll program. Enter the payroll
codes for each employee, then ask for
the paychecks to be printed and sit back
and relax or go play a fast round of
golf.

A hard copy of the employee's payroll
data is provided for the employee and
employer to sign and save for reference.
After the payroll data has been entered
for all employees, you can command
the program to prim the paychecks and
pay stubs.

Selling up the System

This month well see how to build
and manage the data files used m the
package To get started, key in program
listings J and 2 one at a lime. It's not
necessary to key in any lines using
REnarks. however, it will make it easier
to modify the programs later.

After you have keyed in each pro-
gram, save at to disk using the program
name listed in Line 1 ,000 of thai
program. Vou can save a lot of time
if you notice that some subroutines and
remarks arc common to several pro-
grams. Save them to disk using the
ASCII option and merge them with
each program as needed. Since youll
be reading and writing to disk, itV ;i
good idea to make a backup cups ptf

Now lei's take a look at the data files
and ihc programs that manage I hem
The employe* dm a file consists or ■
program ami IiIl 1i>r storing all employee
pLtv, rtiPl information Each employee is
assigned a record number in the file.
A built-in editor allows you to correct
errors and retrieve, print, delete or
move .5 filc.

Finding a Record Number

To use I he editor routine* yuu must
know the employees record number,
I hi- number represents the order the
record is stored on disk. To find the
record number enter *$' from the main
menu of the EM FLOY EH program
(LIST RECORDS*. The program will
read all record* on the di&k and prim
each record number and employee
name on the screen

Editing an Employee Record

To edit an employee record, enter '4'
from the main: menu and follow the
prompts- To make corrections, enter
the new data at the appropriate prompt

then press f.MER, If no correeiicm is
required for a prompt, press LM'tH and
the program will jump to (he next
prompt without changing the data.

Prompts showing commas require
more than one miry. If all data should
remain unchanged, press ENTER until
i he next prompt appears- ff one entry
i.rt i muliipli: input entry is changed,
you most make an entry for each input.
Always verify data when finished by
requesting a printout of the edited
employee's ilk

Frio ting a Record

To prim an employee's record on
paper, enter "3* from the mam menu
Youll be prompted lor the employees
record number. If you enter ALU the
program will print a record for every
employee on file II you enter NONE,
I he program will return lo the main
menu

Entering any number from one lo 10
will print the record for that employee.
A sample employee printout is included
(Figure I). It is self-explanatory, so
when you practice using the package,
you should a \ have any trouble LfftdkH .

MovjriR and n elding i Record

When an employee leaves or retires
from the company, you may wani to
remove thai record from disk Use the
edit function of the EMPLOYEE
program to change the employee's name
lo NO NAME. The program will now
disregard the entire record,

If you wish to overwrite thai record,
select l 5 H from the program menu
(MOVE EMPLOYEE RECORD), The
program will prompt you to verify that
the overwrite is correct. The program
will only overwrite a NO NAME
record, This prevents accidentally
overwriting the wrong one and destroy-
ing valuable dau. I J >ou change a
record to NO NAME by mistake,
change it back to the correct name by
editing it again.

The Employer Dili File

The employer data I He program
stores all the pay period, monthly and
year-to-date (Vto-d) totals for the
employer's records, It can print, edit or
create files much the same as the
employee data record program- Prompts
and inpuis are similar lo the employee
program so t won't go into much
explanation.

You should note that making any
changes in the employee data file will
most likely require a change in the
employer data file, also. Again, a
sample employer prim out < Figure 2} is
shown here and is k 1 1 -explanatory,

I'sini the Package

To uvc these programs, first build the
employee and employer data files. Start
by typing hum * "epipldvee " " and enter.
The EMPLOYEE program will load
from disk and a menu will be displayed
on the screen,

Enter *2'to reserve disk space for your
employee fife, Youll reserve 10 separate
records in the employee Tile, each
labeled NO NAME. A warning will
appear on the screen telling you you're
about to erase all data. This is to prevent
accidental erasure of ihcduia file. Since
there m no data file yet. enter 'R' lo
reserve space.

F nier 4 T f r om the ma i n men u t o i nput
employee data into the data file. Youll
be prom pied for the field entries. The

60 THE RAINBOW Mjrcn ISflS

prompt* are *eif-explmi&i,ory. bui note
that any displaying comma* must have
commas separating the entries an
shown. After all q nines have been
made, yon 11 be asked if the y are correct.
Enter *Y* to save all information to disk.
Enter *N* to erase the entries from RAM
and starl over.

If you don't wish to create an
employee record, you can enter NO
NAME for the name prompt and
ENTER lor ail other* until yuu return
lo ihe main menu,

Errors can be corrected using the
employee data file editor- After each
record is created, you'll be asked if you
want to create another. Enter *Y* for
yen or *N' to return to the main menu.

While this program only handles 10
employees as written, you can increase
its capacity to over 500 employee* by
changing the proper loop values in the
programs. Table 2 shows the program
names and lines to change to increase
or decrease the number of employees.

After building your employee data
file, you can get a hard copy of all the
daia by entering '3' from the main menu
and answering the prompt with ALL.
AJJ employee data will be output to the
primer, allowing you lo verily each
employee record in the file, Use the
editor function to correct any errors,

When your employee data Hie has
been confirmed correct, enter 'IT to load
and run the EMPLOYER program.
This program records all pay period and
y-io-d information for the employer in
the employer data file.

When the menu is displayed, enter
T io reserve file space on disk. Again ,
you will he warned about erasing
valuable data* but at this point, there
is no employer data, so enter b R' to
create the fife on disk. There are no
other entries required Tor ibe employer
dai a fife, The information stored in this
file is computed by the COMPUTE
program.

All employee data is stored in the
EMPLOYEE} DATfts while employer
data is stored in the EMPLOYER/
DA r file. You can locate these tiles on
disk tiMtig ihe directory DIR command.
I used direct access files to save as much
disk space and time as possible.

Some Fhwl Notes

Next month, well take a look at the
programs which actually compute the
payroll and print the paychecks. In the
meantime, it would be a good idea to
prat lice using I he two data file managers
we have just discussed, fry creating an
employee daia file and editing and
deleting records from it.

For anyone not wishing to key in Ihe
programs, 111 tell you how to get copies
next month. If you have any questions
or comment*, you can write to me at
14201 Marquette N.E.. Albuquerque.
HH 87123. Please include a SASE If
you have a major program bug, he sure
lo send along a program listing and
sample printouts.

The "Wishing Weir is a little over
,i ,l\u wkl ru'\\. jiuI the ideas and
wishes keep pouring in ai a steady
pace. Some arc quite good, others are
totally off ihe wall.

The biggest problem 1 have found in
writing this kind of column is Irving
loeome up wiih material which is useful
and interesting to the greatest number
nl readers and C'o( o timers. Unfortu-
nately, ion many readers have noi taken

through his software firm. Illustrated

tbc world could use

Slill. qude often, some wishes will
have a thread ol an idea which will serve
as i he stimulus for a full-blown project
and program listing. This month's
Iisiing is one such example,

Some readers have asked when they
would get to see another "Sccrbo Color
Computer Game." As I gave it some
thought* I realized that I had not
published a real game since ihc appear-
ance of Snail's Revenue in I he See mid
Anniversary Issue in July ol l*>fcLl. Seeing
ihai this is now I9H5, I came to ihc
conclusion (hat ihe "Wishing Well" was
in need uf a game. (After all, being
almost two years between games is
stretching it a bit. so I figured (he lime
was ripe for a little fun and games. I

I hcrctore, i! this mouth'* "Wishing

he surprised. A game docs nui require
I he technical detail and hue kg round
ihai some other articles have required.
Don't worry. Vein 're not getting chealed.
Those of ynu who still don't have
Ft ms brow i >in t Aft will find that this
short listing wilt be easy to type in.
Besides. I really believe ihai the game
you have listed here will be equal in
speed, color and challenge level to some
game* you may be paying for.

The Whh

Almost l wo years ago 1 purchased
ihe first of my iwo MC-IO Color
Computers. As you are well aware,
software Inr this compact little model
was and sldl remains largely non-
existent I quickly wrote up a number
nl programs, winch would lit imo 4K
and fttHl lake advantage of the beauty
and color o) ihc Microsoft basic which
Tandy so wisely pul into ils computers.

One such program was a mini-arcade
game called Demon's Dcfujrue. Ihe
game was much like ihc space-bird
games available for home arcade game*
iind incorporated some ol the lectures
ol the color /ftraAotfr-style games which
dale hack to the early days of Pong,

I old into 4 k, Ihe HASH" code I wrote
had to be extremely small and efficient.
I vciv single hue had to be cllicicnth
utilized There was no room for uustc.
Therefore, f lemon had almost nothing
lor a title card, no skill levels, and had
lo rely totally on the keyboard and
space bar fur action since the MC'-lO
had no provision for a joystick,

I he resulting program was delivered
to I he Programmer \ Guild. Unfortu-
nately. Ihc ntarkcl for MC-IO solt^aic
appeared lo be a* big as the market
foi the MC-IQ itself. < Tandy dropped

Mflien ^ft ThE RAINBOW 77

Ihc MOW from ill line lost year due
to poor sale*,) So much far Demtm*

When 1 decided to offer up a game
here m the M Weir in response to your
requests for one T the klea came along
to revive Derrnm in a new und enhanced
form. With a little- work, Dtnmn
became Demons Defuimc ft. The code
is Mill vety etticicnt hut some new
feature.* ha\c been added.

Hirst, Demon U can use either the
right joystick or rtit- arrow keys and
space bur for action Nc*L 1 have
included ihc option lor using the high-
speed poke to allow for n last or stow
game. Believe me. you are going to he
very surprised in see how good and
rapid a came we can generate without
using Hi-Res graphio

Hie l*ro(Enim

\ lew things should be kept in nond
before you try typing in 0| Uftftg this
program. First, since it u*ei the
pqke&hss . <d fur high speed, keep in
mind that some CoC'os might not be
able to use the poke (especially the older
ones or some C'oloi BA.sK' machines I
If your CoCo cannot use the POKE or
if vou have otilv C olor HAMt , then
delete lines 24.0, 250, 2t»0 and 270

Secondly, make sure you save ihe
program before running ii. If you do
run it first, be sure to POKE^S-i^a to
slowdown the computer before you try
to save it or you witl lose the whole
program.

Ncfct since the program uses a lol
of screen POKE*, be sure to check the
accuracy o| your typing bclorc running
ihc game. A wrong POKE , and pool goes
the program into ibe iwilighi /one of
a loeked-up computet.

Another area of concern should be
your accuracy in typing in the fiotp
statements at the beginning. Some lines
have groups ot just commas, so do not
leave any out. The DAtft creates the
colorful title card which was missing
from ihc original Demon.

You will notice that some lines
include lowercase letters in the listing.
Be sure to press SHIFT 0 to get the
reversed lowercase letters. Shift again
to finish typing any uppercase letters.
This should he no problem for any of
you who arc old pros ul CoCo program-
ming hm might be new to our newer
ownei s

Finally, ihosie of you wiih tbK
Extended computers may wish to
PCLEW 1 before keying in the listing,

This should free up enough memory

for those of you who need it fjt is
always hard Tor me to tell how these
will tit since i do the programming on
aMK machine, A PCI ERR 1 never hurls,
bui I6K Color Mstt users will not need
or be able to use this command.)

the Illusion

I here iiic a lew iricks which I used
in this program to greatly speed up (he
action. One trick involves the positioning
of the shots you fire up the screen.
Rather than draw Ihc stun all the way
up the Screen anil have lo reset u after
each appearance. I only have the shot
appear a few times on the screen. This
will goc the illusion of it traveling up
the screen bui di>cs not waste the time
and memory of drawing n nil ihu way
up the screen. Whcnymi >cc the resulls.
y. i ■ i ■ -a ill he ama/ed how *ell rhis
technique works

Also, rather than check lo see if a
square is set or nul, I have stored that
inhumation in a multi-dimensional

u . . . you are going to he
very surprised to see how
good and rapid a gamv we
can generate without using
Hi-Res graphics "

array, Checking the array is much faster
than testing Ihe screen The speed we
pick up is impressive and you will never
notice that this is Ihe method we are
using.

The Demon bin! uciunllv appears to
fly by printing two different positions
ot the bird on top oi each other over
and mcr again. I his Happing gives the
illusion of a living bird

Overall. Ihesc simple illusions go a
long way toward making this game look
arcade quality

r laying the Game

Demon "v Defiance //is actually tiuiic
easy to play, but lough lo master. You
control a cannon al the bottom of ihe
screen. A Demon bird hovers over you
firing laser bolts at you. You can shoot
the hud, hut your main goal ii to blast
out Ihc colorful force shield ul Ihe top
of the screen,

I'niurtunately. the Demon has help.
\ ncutrali/cr beneath your cannon will
destroy you if you lire while the red

square is directly below your cannon.
You only gel five lives to start with.

Clear I he screen and you will gain
a nc* life; Your score and lives arc
recorded at the bottom of ihc screen.

Sound easy"* Well, here is where the
skill level comes in. As you blast out
the shield, the Demon will rebuild pans
of it. l evel one does not rebuild the
shield but higher levels will ut increasing
speed. This new feature really makes
Demon It a tot ul fun and rather
difficult to completely master. When
the game has ended, pressing I Mt U will
rerun the program.

In time, I expect lo see some of you
listing your high scores in 1 lit KAIftmW
Scoreboard.

Is this cffkicnl Bask code? Well, the
actual game lines only Hike up about
Mi -hort lines Bj the lIIu iem placing
of I then statements, ihe program
runs in a relatively straight line with
little looping or messy, misplaced
subroutines.

Another way in which 1 kept ihc
speed fast was by noi making this listing
work on an MC-IU as some of my other
recent Color BASIC programs have. As
you may recall, in those 1 included a
variable MC which was equal to ihe
offset value for the screen pokes on the
MC-10 If I had included thai value,
the program would really have slowed
down and taken up much more memory.

Besides, it would never still fit irt 4K
as the original Demon did. Therefore,
those of you with MC-10* will have
to iry to track down a copy of the
original Oemtiti if you really want it.
{My guess ii that very few CoCo
programmer have tmty an MC-10.
Odds are. if yuu have HAlMtoW. you
have a regular CoCu as well )

f one fusion

There you have it. a small, efficient*
rapid, colorful CoCo game. I tried
translating this to ihe VTC-20 just to
sec how it would work und let me tell
you. I gave up after a week Many of
you don't rcali/e how lucky you are lo
have such an easy-to-use language in
ihc CoCo, The Commodore language
is an absolute nightmare when il comes
to screen positioning of character codes.

Now ihut I have gotten my feel wet
into game programming again, y ou may
see a few more brand new games
Popping op in upcoming months. I
might even create Snail tft or Snail:
The Final Chapter for an upcoming
issue like the anniversary issue Some

70 1Mb RJUNHGW Mftrrr- 'ftg*

of you might wuni losnggc*! &o me game
co nee pis or ideas in your wishc.v

Somewhere inside mc. I Jo have a
graphicv Adventure Homing around,
hut I am waiting for just ihe right
stimulus to eome along so J can make
it tin absolute killer (Wait! Maybe a
game with killer kes would work, or
a Michael Jnuksou takeoff game or > . .
sec how tfiwy u in in i^trt started?) Only
time will tell.

Oopft! Some I urrectiuns

I have taken great tare in trying to
keep the "Wishing Well" free from
error*, but as can be expected, *omc
quirfci have worked their way into the
mechanism.

For example, some copies of the I cm
Version of the Screen Quiz Program*
on rainbow 0* r*PM ended up with
the word next included in every single
ejatA line. I don It know how it got there
ll i» not on the paper list, but somehow
it crawled onto the ft \istit>w on t*pf.
If you have such a copy, just edit out
the word next in each omfl line at the
end.

Another render wrote to point out
that the check sum values do not work
on some listings if you are using ihcm

(you know, those tunny numbers at the
top of the list}. Since I write these
programs using a full screen editor,
sometimes a few blank spaces get
included at I lie etid of the line. Th Li
mi ally throws nil the check sum valacv
j have tried tti *(.iSve this by U£tnjj ihe
regular EDIT command lo rccdu I he end
of eueh line sifter the pmgtam is finished
>o ihat ihi.s does tun occur again S . t \ \ \ 1

finally, u tew readers had problems
with the C&Co Itnunumviu PfpgrWrW
trom a few months ago. There arc nC\
any real errors in the listing. The errors
some of you have gotten have come
from not understanding fully how to
use the logic of the program, which is
probably my fault anyway,

For example* in an eight-man bracket,
some of you found the computer would
lock up if you included eight names and
only ranked [he firsl seven.

If you slop to think about it. you
are asking the computer to sotvt i
problem which it cannot do with the
formula I have written. Logically, if wu
have ranked seven of eight players, you
have, in facu ranked the remaining
player in position ciuhi I herd ore. this
problem i* avoided if you only rank six.
or rank all eight in the D&Tp line. The

same goes with 15 out of 16. just rank
all in

AJso, you cannot rank zero players.
You miM rank ut least the first or you
will jiL-i :ni I run Vgam tin* a the
way the logic in the formula has lu be
written or else we would have to include
quite a tew E f TH£k statements.

Finally L when yon arc doing Ihe
runkiFiir nl .ill ciyhl ,i» I fi.vnu -.lumld
include the lol lowing line.

For eight bracket:

194 IF NW=8 THEN FOR mTONW:
PR*( I |=PL»| 1 ) :ND(T : Krr02?4

For sixteen bracket;

1^* IF NJ^IG THEN TOR IMTfWJJ:

Pftt{ r 1 -t*L% I J | '.Hltt 1 tGTlTlWB

Somehow, these lines got fcfi nut o)
the listings. This should clear up any
problems some of you may have with
the programs.

Again, thanks tor pointing these out.
The instances in which these error*
would occur just never came up hecau^c
of the way in which 1 was using the

program.

matter how careful we are with our
money, there never seems in be enough
at the end of the month I always
wondered where U all was going-

As a result, I knew that this would
be a perfect job for .1 great record-
keeper, my Color Computer. So, I
wrote a program thai would not only
show bow much money was going 10
individual expenses each month, but
that would accumulate expense for the
ycar-to-date. as well as express every
expense as a percentage of gross
income

This would be a ureal help at tax time,
too. By forcing myself to keep a daily
record of expenses, a nd keeping all the
receipts. I have a pretty good idea what
] spent, for instance, on items on which
sales tax was paid B> making simple
calculations, maybe I could beat ihe
sales lax tables (which always seem too

If you arc realty serious about
keeping track of your finance*, you
must keep a detailed record of what you

By J.D. Ray

emarkabk progress has been made
with the Color Computer, and the
software available is staggering. When
t passed the phase of discovering what our
marvelous machine could do, 1 began a
successful quest lor useful software for various
and unique applications. Color Computer
owners can be very selective, and with
magazines such as the rainbow, the choice
is sometimes very simple.

I was presented a challenge by a close friend
to develop a system he could use to help
manage his rental property. My first thought
wa* to set up one of the available spreadsheet
programs, or perhaps even a database to fit
this specific ap plication . J proceeded in this
direction, but soon learned that the application
would be very limiting, and require constant
modification of the "packaged" software,
Therefore, I began to develop the following
program system.

First, 1 made a list of what we wanted the
program to accomplish:

(J. D, Ray is minister of music at the Cooper River
Baptist Church in North Charleston. S C He ?njo i >
water skiing and woodworking as hobbies. He has
two children. Jeff and Jenny.)

If A file program lo have pertinent
information available when
needed, such as renter's name,
rental dale, deposits, phone
numbers and mortgage
informal ion.

2) A financial journal to record all
financial transactions each month.

3() \ financial summary of income
and expenses on a mnnthU basi.v.

4) A financial summary of individual
property transactions on a month-
ly basis .

5) A ycar-to-datc summary on in-
come and expenses

6> Applicable on a IMC D=A System

with primer options
7) Sufficient screen prompt* to

prevent keeping paper nole* and

instructions.

We soon discovered t hut unc program
*uuld be too cumbersome and too large
for even a 32K system. I developed the
system using four different propftWIlO
perlorm the various function*. A menu
program coordinates the entire system.

Progntm Summary

it f:\TM ENU seta up the basic
foundation of the system and fdtowi
you to enter any special command's ihot
wilt be needed lor the other programs,
Since graphics are not needed, a
PCLEfiCl is added to lake advantage of
all available memory. This wiU be
especially important io I6K uvcrs You
can also insert commands to alter your
primer ftaud rate Once the Baud rait*
tsse< in the menu program* you do not
have to MM ii again in the oilier four
programs.

program needs to be run first so you
can scl up your accounts Once cstab-
li-dted. you should mH have (0 tlttl i his
program except to change ihe accounts.
The first menu will let you enter
property codes ta three-digit number,
letter combination), income accounts or
expense accounts.

Property codes are codes that you
a&sign to your various properties. The
codes can be set up by location,,
acquisition or value. Expense accounts
are those expense categories that you
determine will be used. U» categories
such as maintenance, advertisement,
Utflhics, mortgage or loan payments,
etc.

1 advise you to scl up at lensi two
miscellaneous categories so you can
expand later. You can change the
account names at any lime, and these
will he reflected immediately in |be
program However, ihe previous file
summaries will not refteci this update.
Be careful when adding accounts after
1 lit- program has been in use for some
lime. Income account* are similar to
expense accounts and you should use
such categories as real income, refunds,
deposits and miscellaneous.

Dodging the lane jumpers with

By James W. Wood

"WT^i/ei is a Inch rcsi*liilu>Ji yarue
which involves dodging Lars as

The roiid animal inn is accomplished
by storing three different sets of center

drawn and \toted as anavv I hey can
he quickly PUT onto the screen. Your
races is at the bottom of the screen.
Use the let I- and right -arrow keys to
dodge l he oilier cars a* you fl> b> ihem.

As the game proceeds, it becomes
mure difficult. After a short while, the
cars that appear at the lop <d the screen
will jump from their original tunes into
the other lane. The car* only show in
five positions as they move from the
lop Lo the bottom of the screen. II one
lane jump doesn't cause you to rear-

end i hem, the game will later cause the
curs lo possibly jam planes in the second
and third positions us they come down
i he screen.

There is room for improvement in
Han't. (Isnh that I her best pan'/) One
could add a hotter title page or add lines
to allow more than one crash, The crash
sequence could stand improvement:
perhaps a high resolution crash could
be stored nn graphics Pajje six and
shown at the run mem of impact. Study
the line description lo decide which
enhancement you will program, or

Flow Rate of Return

lis William S. Itoiiiu ll

In business, projects arc attractive if
they produce a rait* of return on
investment greater than a company's
cost o\ capital. Thi> produces n net
inflow nl cash into the company. If a
cum puns has unlimited funds, it invests
in all project having a rate of return
greater thun the oim pany eosi oi
capital In reality, projects arc rejected
even ihoujm they lime a favorable ratc\
of return because funds are limited.

Capital budgeting rank* projects

ness and select (he *cl which ntuximi/cs

considering those tor invest men t which

rate r,l re i U in. the cnsl of capital.

The program described in this article
determines the CFRft and PW or a
project and allows sensitivity testing of
the assumptions made in the
calculations.

The required parameters lot cale il-
lation of CTRR and PW lot a project
arc;

1) Expenses by year

2) Savings by year

cost of operations. They arc not

opposite nl cspciiics and represent the
in How of cash from the alternative in
question Ispenses can be netted out
of savings or both can be entered
separately. Examples of expenses arc
labor, overhead and raw maietiuK.
Savings result from prcvenlcd expend-
itures or reductions in labui, over head
and raw materials.

Capital expenditures arc invest mcms
in building and equipment which are
allowed by law bo be recovered over
time through depreciation,

The lax rate is the percentage of
profits which the organisation must pa\
to ihc government. Investment tax
credit is a means ihe government uses
to stimulate business investment in
capital equipment Generally in the year
following the capital expenditure, the
. i minion is not taxed lor a percent-
age of the expenditure.

The required rate of return depends
on Ihe nature of the company involved

fcMrch HKS THE RAINBOW 131

If the company finances us operations
b> borrowing, the cost of capital is the
borrowing rate, If projects have a rate
ol return greater than the borrowing
rate, they will be profitable. fhcreforc,
the required rale of return is the
borrowing rale

In companies financing their itera-
tions by common stock or a combination
of siock and debt, ihe cost of capital
is more difficult to determine. In these
eascs. the cost o| capital may be a policy
variable supplied by management as a
benchmark for comparison «r projects
in general. It may he unrelated 10 the
true cost of capital lunds lo the
company,

I he PW of a projecl is defined as
the net cash How |inf1uw*oult1owi when
all flows haw been discounted to the
present. The basis lor this concept ts
a dollar invested for one year is worth
more than a dollar m ihc end of the
year. Similarly, a dollar received u year
from now is not worth as much as a
dollur now. The value now of a dollar
received u year from now is:

1 d+r).

where r' is the rale ol return .1 dollai

cost of capital. The vidue now of one
dollm received iwo years from now is,

And in general, Ihe value of a dollar

The straightforward answer might seem
to he SUM) since $1,000 went out and
52,000 came in. but this ignores the
alternative uses of these funds.

Cash llow rate ol return tCe-RH)
is defined as the rate, %* which makes
PW wiuril to zero in the following
equation:

PW = CH * CF2 tl+r)«l + CP*,
fl+r|*»2 ♦ + CFtN\(l+r}«*N-t

where "CFN M is the net cash flow (in-
out! at the beginning ol year *N* for
at the end o! year N-l).

CTRR is analogous to lending >um
ol inunuv and receiving annual payments
which eventually pay oft the original
deposit plus 1 rue re si The interest rate
earned is like CFRR

To be accurate and of use in business,
tax and depreciation effects on tUXM
must be considered. Depreciation is a
method for recovering the cost or
capital assets over lime. Government
policy determines how quickly the
investment can be recovered Faster
recovery is moie beneficial to business
because of the tune-value ol money.

Money recovered sooner is more
valuable than money recovered later.

There are many methods of depre-
ciation depending on the type and life
ol The asset I *in.j» straight line depre-
ciation. 20^ of an asset's value can be
recovered each year after the first,
assuming a live- year tax life. It is
recovered by subtracting depreciation
from profits. This means a company can
shield a portion of ns profits from taxes
by depreciating its assets. This is an
incentive for investment in new assets.

An accelerated method of deprcciu-
lion is Sum or the Year's Digit*
fV>W>i II an asset huts a depreciation

depreciation factors is usually one.

Double-declining balance is another
accelc rated method of depreciation. In
the first year alter capital expenditure*
the depreciation factor is two divided
f>> the asset life. In subsequent years,
the icmaiuirig fraction to be depreciated
is multiplied by 2 (asset lifcf The

PERT: Project
Evaluation and Review
Technique

Rv Jur-jr Mir

Having the ability to evaluate and
review ptojects can be very
useful, at the office as well us
at home, especially when time bl ol the
cue nee and you want to make sure (hut
projects arc completed on time with a
minimum of supervision.

There are many types of **Pf : ,R I "
programs available on the market.
Some of these arc quite sophisticated
(and expensive) and require a large
mainframe in which to operate. The
PERT version I have developed fur the
Color Computer is a simple one* yet
U has sufficient "bell* and whistle*** to
make it quite beneficial at work.

Following are the main features of
the PV.R T program

\\ Calculates minimum 1 1 nit: needed
To complete project.

21 Calculates probability ol comple-
tion by a target date.

3) Determines whether activities are
critical or non-critical.

4) Calculates expected duration and

standard deviation for each
activity

5) r>eK'rmines earls and late start

and finish times
b\ Calculate* slack lime for each

activity (if any!

In addition, several output reports
are available:

1) Worksheet I or developing a prece-
dence table.

2) Complete activity schedule,

3) Aelivil y scried u Ic by response biJ n >
4* Complete Uanu type schedule.
M (iantt schedule by responsibility.

The activity and tiantl schedules
both clearly indicate the ''critical"
activities so ihe user can concentrate
on evaluating those activities, as well
as monitoring progress, as the project
advances through the various stages of
completion.

The program is fully prompted for
all input data, *o these will not be
covered in detail The input and output

a cassette system, you will have to
change those routines so data is saved

lo tU!->oileS instead nl disks. \\sv r a

printer is necessary lor the various
out put reports.

Please note that a loial of 100
activities is i he maximum established
by 1 be pr mmim f'his Li n iii anon can be
changed hy changing ihe Dl rt statements
at the hcginninu of the program

In nrdei to proper \\ enter all data.
,1 precedence table (which activity
comes before another activity! is
necessary. After you enter all of the
activities, you will be able to develop
a worksheet for this purpose. After you
have the worksheet completed, you can
then run the program in its entirety.

Here arc some hints Tor properly
completing the worksheet

A "nude" ca;i hi- '. u^-.-Ji a-- a I -
in the project ( hat is. at which stage
an activity must commence and al
which stage it must end These nodes
serve as ihe key for determining the rest
of the calculations in the program, so
care should be exercised in planning this
aspect ot tile projeei.

The hi art node ut each activity must
appear as the end node of some other
activity tn the project In other words,
all activities must be linked with each
other fesceptions arc those activities

More than one activity can have the
same itart or end nodes: just make sure
the beginning node of an activity
coincides with the ending node of the
activity that must precede it* Here is
a simple example (cooking a meal):

Bake pot aloe*
Broil meat
Cook vegetables
Serve meal

Buy all Ingredients
Man rone meal
Wuvh tcgcluhnlc*

Start
Node
I

End
>CMk

In (he example, you cannot broil the
uuMi (start node 3) until the meat is
marinated (end node 3), Mao, this
project may require two people since
ihcre arc two activities siartiag al the
same node (i.e., one marinating the
meat and the other washing the
vegetables).

11 there is a start node which docs
am coincide with an ending node in one
i0 ihe filter activities, I he program will

Slop execution and inform >ou ol those
activities for which starting nodes must
he Lhiinged

The best way to get used (o the
prtTg r u m is t o ru n som e si m p1o c \ urn p1& ,
,is i he one iioieil I hat w;iv, you will
get .9 good leel In/ till the prompts for

reports, as well as the various ways in
which a program of l his nature can be
put to good use.

I ol ten gel involved in some complex

T-bill Computation

By Walter J. Tucker

On Monday of cuch week the
U.S. Treasury borrow* billions
of dollars by auctioning LVwcck
nnd 2fr-wcck T-billMireiisury bill*). The
52-wcck T-biUs arc auctioned on the
fourth Thursday iirc-ufh mumh Vlan\
of ihc T-bills arc purchased to th..
public mi ihc "average" price, which is
a v it i la blc uf I c r i he a u ct ki n . l"h e d i>e n u n l
rate is published on the following day
in ihc financial pages of many news-

fWhttif Tui kvr.u nwd mginrrr frttm
!h t Voict "f Amenta" ami an ami
ratiu* amateur with t/w tuit KAUiQ.
Iul\ hrittfii t)umrrtui,\ mhrr fmamtai
prt*xrurn>. }

r Some oi these also include the
price ( The results of the most recent
a action can he obtained from a Tele-
phone tape. 2t)2 2;s7.J|(K).)

T-hfif tUmpuftitum provides Ihc
investment rale which equates the
coupon rate of other iti vestments, a*
well us the number ul days to maturity .
profit, and the amourtl of your federal
income lax on the T-bill. The interest
on I' S. I rcasury bills is not subject to
state income iax.

If your state has an income las, the
amount ol this savings is also shown,
the pnoln on ;i 52 -week T-bill differs
I rum the mveitmeni rate, which is
comparable to the coupon rate on an

investment which pavs interesl
semiannually.

The program requires the discount
rate. It also requires cither the com of
the T-bill or the exact number of days
to maturity , If neither of these arc
available, use- Ml. and .1M Jays to
maturity, respectively « for 13-, 2cv and
52-wcck bills, as these figures arc likeh
to be accurate since ihcy change only
when the day o I issue or maturity would
tall on a holiday.

purchase U,S, Treasury hills call 202-

By Raul Poulosky

his I6K ECB
graphics display explains
exactly why there arc so many CoCo

on the first anniversary of having my CoCo,
CoConuts is a program designed to be expanded
upon, We challenge ambitious programmers to make
another screen or two. Good luck?

So, You Want To

Many people write a piece of

people could use and enjoy 1 lu re are
three ways to go: donating ihe soli ware
to the public domain by sending il lo
CompuServe or other hu lie tin hoards,
submitting it lor publication in IHF
R MS how or another magazine, or
trying to sell the program.

People who decide to iell a piece of
software that they have written then
need to decide whether they want to
sell il themselves or if they want lit
submit it In an existing software house.
Ihcie arc many pro?, and cons related
lo each choice. Hie final decision i>
truly an individual one. often hnscd on
the amount ol hme and money the
author has in invest in his 'her program
and nut on the quality of I he software.

its database of registered company

used a name already in use or a name
that is very close to one already in use.
You should not start using your
business name until your slate has given
you ihc go-ahead.

After i he slate OKs your new business

You will need to develop a logo to use

The Stock Market

By Patrick H. Lowrie, Jn

Yuu ton gauge your own perfor-
mance in the stock market with
Stock Index. It works equally
well lor measuring ihc performance of
mutual funds, bond** or anything where
the price fluctuates with time.

Measuring yimr perEtirmanci; js cum
if you just buy same shares nod hold
I hem. The price of the stock limes the
number of shares you hold tells you
whether you Ye made money or lost it.

But. when you hoy a few shares of
this- stnuk tddii>, j lew more shares in
another stock in a couple of weeks or
month*, then sell some shares after
another month or so t how can you tell?
With some slocks increasing while
others arc decreasing, determining the
nei performance can be a chore.

Stock Index will take the work out
of iL It doesn't care whether you're
buying or selling, or whether you Ye
reinvest i ng the d iv id ends o r t ak i ng t he m
in cash, h will faithfully show you not
only how you are doing r but it can show
how well you would be doing if you
had invested different ly t or how any
group of stocks, bonds funds, elc> are
doing.

It s very important to note here thai
you don't have to actually buy stock
to use this program. On the contrary,
this program provides an ideal tool by
which you can experiment with hypo-
thetical purchases and sales to evaluate
an investment method before you spend
any money!

Running the Program

Once the program is loaded, run il.

f Patrick Lowrie, president of Lowrie
information Systems, inc., holds a
bachelor's degree with special honors
in electrical engineering. He has heen
writing programs professionally and for
fun since 19&0J

To pass the title, press any key. If you
answer *N M to the query about the
printer, the program disables the PRINT
commands so you can't inadvertently
request a print (which would cause ihc
program to lock up without a primer
attached I.

Amount Invested

After you have entered the date, the
program will prompt "total invest-
ment?". Enter the total net amount you
have actually (of hypothetical^ I spem
in purchases of shares as of that date.
I.lf you don't know ihi* number, or if
you want to just compare stocks, for
instance, against a baseline dale, see
"Determination of Baseline" below,!

tf you want to know precisely how
your investments ate doing, this number
should include broker's fees, coal of
wiring the money or com oi the certified
check, and any other costs immediately
associated with the purchase. If your
purchase was for less than SI, 000. it's
more important to include these costs,
as they arc a larger percentage of the
total investment than for larger invest-
ment*. They arc real, however, so lo
ignore them is lo make the picture look
ivuiiL^ksn uv-wv i\un :i i cully iv

If you have sold shares, reduce the
total amount invested by the amount
ai cash you received from (he sule J and
he sure to reduce I he NO SHARFS
by the number sold).

Dividends Taken In Cash

Next, the program will prompt
"Total dividends taken in cash 0 "* As
any dividends you have taken in cash
are part of the return on your invest-
ment, entering this value will allow the
program to more accurately compute
your performance. (Any dividends that
yuu have rein vested will increase the
number of shares of the stock in

question, and should be included in the
HO. SHARES.)

libit of Kivtries

Next, the program displays a table
of three columns. The first column is
for entry of me identifier of the stock,
fund, bond, etc. This identifier may he
up to eight characters long. An example
might be E-'DM or FREEDOM for a
mutual fund named "freedom," or
GMC or GENMOTOR for Gene™!
Motors Corporation,

If you have several different stocks
or funds, a list of names and their
abbreviations is handy, Press ENTER
after enlering the name.

The NO, SH ARES column is for the
number of share* you own [or owned)
of that stocV or fund on this date. If
your investments arc in mutual or
money market funds, thii number
should be carried out to three decimal
places, for example: 34 567. Press
ENTER after entering the number The
cursor automatically moves to the next
column

PRKT is the price per share on ibis
date. Your broker (if you have one) can
tell you this price, or you can get it
out of the newspaper for this dale. It
must be entered as a decimal rather than
as a fraction, and may be carried out
to two decimal places This corresponds
to bow the prices are listed today in
most newspapers, though they are
usual I) quiited m fractions nvci rhu aii

This process is repeated for each
stock you own or are analyzing You
may List up to 12 entries. But, what if
you have more entries than 12?

This program will let you list as many
entries as you wish flit explain bow a
bit later 1 1 but I hey must he in blocks
no greater than 12 crimes long. When
all (or J 2) stocks have been listed, press
ENTER in the "Stock" column of the
nest row. If you have listed 12 entries,
the correction phase wilt be automat-
ically entered,

Corrections

The entries will now be relisted on
the screen followed bv the words
CORRECTIONS? (Y/N). If you made
□ mistake during the entry of the slocks,
now is the time you can fix it In
response to your pressing 'Y\ the
program will prompt fcMTFR NO, OF
LINE TO BE CHANGE O This number
must be followed by ENTER.

You can also add slocks by selecting
a number higher than those listed, (If
you enter a number greater than 12,

the program will announce "improper
entry," and request "'Correction?"
□gam,) That is, if three stocks arc listed,
you can add another stock by selecting
a number larger than W. The program
will always list the next entry with the
next successive number, so, if at the end
of a three row entry, you entered a '5'.
the program would enter a "4' because
thai is the neKi number in the series.

"'Slock Index doesn't

reinvesting the
dividends or taking
them in cash. It will
faithfully show yon not
only how yon are doing,
but it can show how
well you wo old be
doin£ if you had
invested differently , .

You can also delete a stock by
pressing ENTER without any entry in the
"Stock" column of the row to be
deleted. Following each correction the
program will relist all entries followed
by CORRECTIONS'.' (V,'N) You will
stay in the correcting mode until you
respond to the "ComectionsT prompt
with "N".

Remits

When you have completed the cor-
rections, the pi op ram will print the
results, of the calculation on the screen.
The screen will fust list lite date of this
analysis, then the amount invested,
dividends taken, and a table of all
entries with the value of each entry
noted in the right-hand column.

If the total number of entries exceeds
six, the program will state at the bottom
or the screen PRESS ENTER TO
CONTINUE, Pressing ENTER brings up
ihe res i of the data.

At E he bottom ol the table sou will
note I row entitled AGG I, **AGG"
stands for aggregate. This row is the
one row equivalent to all the other
entries. This is the feature of the
program that lets you analyze a* many

iti vestment units as you wish. Before
[ explain how, note below the AGG I
row the "total value " of the entries
listed, and below that the "Index."

Index

The Index is what this program is
all about. If you haven't made or tost
a penny, the Index will be 100.00, This
means you still have 100 percent of your
investment.

If you have made money, the Indies
will be greater than 100. and the Total
Value of your entries may be greater
than the amount invested.

Please note, though, if you have
taken appreciable dividends in cash, the
"total value* number can be smaller
than the "invested to dale." while the
Index is greater than 100 This is
because the program includes these
dividends in its calculation of the lntkx T
but they do not show up in the value*
Of the investments listed. Nevertheless*
if the Index is greater than lOfl.OQ, you
have made money.

The Index will not be below 100 00
until the value of all your entries plus
dividends taken arc Jess than the total
amount in vested .

Printout

If yuti answered "V* to the "printer
connected?* prompt, vou will see at the
bottom of the screen PRINTOUT fY
N)?, A "Y" response to this prompt will
result in a dump of the entire table to
ihe printer. Since the printer is not
limited by screen size, the complete (tip
to 12) entries are printed on one table

Additional Entries

If you answered 'V to the "printer
L'onncctcd?" prompt, or if you answer
*N" to the Sprint out?" prompt or at the
completion of the printout, the prompt
MORE STOCKS? will appear m the
bottom of the screen with the (Y/N)
flashing

If you respond with 'Y\ the program
returns to the stock entry ublc. but it
firsi enters ihe AGG I row to this new
table as entry tt I . This includes the total
aggregate entries of the first table us
the first entry of thU new table. As a
consequence, the results of these new
entries will include the results of the
previous entries as well

By a wcri ng * Y * i o the "more stoc ks "
prompt, you can build your total
analysis to include as many entries as
yon choose Each time a new AGO is
calculated, the AGG identifier will
increase by one {the first will be AGG

The most difficult type of math
example for many students is
often the verbal problem. These
arc problem* thai iclt a short story and
a*x a question, and [he student must
decide how the information given can
lead lo a solution Many time*, the
solutions arc n o t o b\ ious; these so luti am
become obvious only after much expla-
nation and practice.

It is not usually the math of these
examples ihnl thwarts students. The
difficult) ij in deciding how to solve
the problem. The information must be
internally processed in a meaningful
manner. The child reaches the point
where the solution becomes some
arithmetic function of the pieces of
givun Hitormaium

There is a unique lormula that
accompanies each ol these types <il
examples, When the formula is familiar,
it is a matter o| plugging the numbers
in I he right places and performing the

solid foundation early on lo make the
road ahead a Utile lc*s painful.

Verbal problems come in an almost
endless variely. Among them are
distance, mixture, coinage, age* perime-
ter and interest problems. Fach has its
own distinctive method of obtaining the
solution. Distance problem. 4 !, for exam-
ple, use variations of the formula Rale

that will be charged. The method for
computing the amount of interest owed .
therefore, is based on the principal, the
rate and ihe duration of time I he money
is borrowed.

Almost all ol us have borrowed
money for one reason or another
Mortgages, ear loans and even charge
cards are forms of lending. Small
amounts may He borrowed for u period
of a year, however, large amounts arc
usually borrowed lot a period of years.
It should therefore be explained to the
children that the rate of interest is per

Reading vs. Computers

Is there a problem wall literacy in
this country",' I have read that at
lensi 2} million adults arc function-
ally illiterate, and ihu( number is
reportedly growing each u'ar I do nor
know huw "functionally" is being
defined, but lor the sake ol argument
we can accept ihe figure, or at leusl the
uic;i ihni a Ifi i>1 people cannot read.

It has also been reported lhai honk
reading rot people under 21 years of
age has declined 13 percent in the Inst
five years, So, even if people tan read,
ihcy choose not to,

Not in mil studies have addicted the
problem ol students not being able to
read in school and even teachers who
cannot read It does seem thai this
country should have the highest literacy
role in the world, and we should ideally
have a literacy rate over 99 percent

Recently. I overheard someone bilk-
ing about siudenls' low level of reading,
and reasoning: that technology is the
cause of tack of ability to read. With
computers, arcade games and video
per lor mances, the argument goes,
students do not take llie time nor have
the desire to read The lure of the
u-k-UMon xcri-L-Ei. w rJi .is c-om pu i ot
generated graphics, is too much com-
pete ion for hooks or maga/uie*.

I disagree uuM this position I here
has always been competition with
hin>ks, including such thing* as fishing,
cloud watch-.ng. tree climbing ot mst
plain "hanging around " It m,c as a
nation dn not read, ihe laud lies not
In our electronic gadgets, hut in
ourselves. i My apologies to
Shakespeare.)

Current technology may impose
many ills upon society, but a lack of
reading is not one ol them. We may
lose our privacy, our dignity and even
our definition of "good" lasle. but
technology will not cause us (o lose our
ability to read.

Mow the microcomputer is hut otic
component of current lechtiolui.^ U
however. i> more often accused of

calling a lack of reading than some ol
the other technologies. such as video
recorders. Il is my contention that
current technology (including the
microcomputer! wjJI help eliminate
itl iie racy, il is gratifying to know that
olhcrs. in positions of prestige and
power, share this view ,

l-a*t year* Congress requested a si udy
on the future of books, given ihe
e lee ironic method*, of access to infor-
mation. The library of Congress
recently released a report responding m
the ret) il est

1 1 is true thai technological e?t pans ion
has ' deprived the primed wind of its
I radii tonal monopoly on access to
knowledge* information, and the mas-
lerpicces of civilization. " according lo
the study. Losing the monopoly, how-
ever, does no i mean people have less
access to knowledge.

The report goes on to explain Ittal
nev, technologies expand access lo the
world of books. For example, many
classical pieces of literature arc cur rem ly
being reformatted to movie or lelcv ision
pi i " 1 ii n i ions T ' h esc "i r a ns lai io ns, " d ra w
more people to libraries and bookstores
lo read the original works.

182 THE HAHNflOW Mju n 1585

In o more direct sense, the conversion
of books and newspapers lo mierolilm
increases the availability ol sources of
in form nil nit; sources l hut are being used
by the American public. Computers,
naturally, arc used to compile and itOCB
more enmnreheasive reference work*,
and greater detail of information, than
ever before.

The report claims ihai far from being
a threat to the printed word, new
m forma turn Technologies promise lo
aid in i hr spread id knowledge and the
war on iUilcrac} In taci. the "culture
of ihe hook" benefits from the devel-
opment BJ computer^ television and
even radio.

So, hack to the ordinal thought for
a moment. On Orsi glance, it muy
indeed appear ihai Modems are nut
rvudinu as much as in the post, because
ihey Have entertainment in their home
nmrrtn'ompulers. I hat position is a
simple response lo a problem, and din.''-
not even stand up against "common
sense" arguments.

In otdct tii operate a computer, even
a relatively inexpensive, but high
p ^ ■ vv ._- r i.' l1 machine I j kc the (."oli.ir Com-
puter, a person has to read directions.
r\lso, computers lend to be in affluent
homes more than in poor homes, and
students Irom al fluent backgrounds
usually lend lo read better than their
peers of lesser economic means.

And, anyone who has had a computer
more ihan three weeks knows thai the
machine docs noi reduce paperwork,
sun ply processes paper more quickly,
Producers of all thai papei hau- lit be
able to read it.

Ii may be true itiui students today

iU> nol read a> wdl ;isin pa>[ general inn*
However, u may nol he true, for several
reasons I he mo*i simple explanation
tor ihe lack of irulh of this assertion
is in the numbers and types of students
lakmg tests now, compared wiih stu-
dents taking tests 20 ycat* ago.

It used to be that only college-hound
students were administered the naiion-
wide letting for college admission.
Then* the trend changed to testing
almost all students which could be
done easily because ot computers. By
adding lite lower academic students lo
the group taking tesis. the scores have
to tied inc. If scores of Jess academic
students are included in national
results, the average (mean) must de-
crease. In fact. I understand some
prmupah ha 1 , c improved then school
scores dramatically by only having
selected students take the tests.

to ■"urn.- ropettv it makes no dilTcr-
cucc whether students today can read
as well as their counlerparls of past
years. It is simply unforgivable for any
student in America today to not be able
lo read. The solution to increased
literacy is noi in abandoning technology,
but in using technology to open more
duois lor students as well as adults. In
essence, nist whal ihe study from the
Library of Congress found is starting
to 1 1 Lip pen I ducat ors have a respon-
sibility to use all available means to
provide reading skills to students.

I am pleasantly surprised at ihe
availability of computer software for
education, including programs for
le.idine. \ few days ago. a person I
work with asked me aboui educational
s^iliware lor the Color Computer. He

has a CoCo, mostly for his daughter's
use, but Had noi purchased many
educational programs.

We started going through THf hmn-
ttntt . looking for educational sol t ware.
In ihe firsi .10 pages, we found adver-
tisements from eight companies for
educational software. Me ouit making
notes at ihai point, realmna ihe
abundance of available software. This
can be contrasted with jusi a lew years
ago. when almost all advertisements
were for games.

So. Ihe lack of software is no excuse
lor not using the computer to help
students rendu Neither is the argument
thai computer^ ,ire detr imcnial in
reading. Wc must use ihe computer and
other means at hand to improve reading
aptitude of students.

I realize that you read, and cur
probably read well. After all, THE

10 use both u printer and a modem, you have la either
plug and unplug each of them lime and again, or buy a

sach a switcher, you si til are unable to use both at once
And some find the need to switch annoying So, one reason

For those of you using OS-9. there; is even more reason
to consider buying a hardware RS-232 port. Because the

the power of 0&9 to print out material as a background

A hardware RS-232 port is also a must if you plan on
having a second user hooked m through a terminal under

Of course, you must cither be able to write or buy

Differences Berwcen the Device*

Unlike the PBJ product which comes only with traces
provided for soldering in an f PROM socket, the Tandy
product comes with a terminal program on j 24- pin, SK
by K-sociclcd ROM inside the device. I his might stem
lo be a tremendous .id vantage, until you realize lhal the
program supplied cannot use the disk drive. This is a serious
limitation, because of its lack of support for disk systems
.11 1 J its overall poor structure and quality* I would advise
potential buyers to ignore the supplied software in the ROM
m the Tandy Pa k, and look at that pack a* solely a hardware
port without a oft ware.

When one does thai, the Tandy product docsn"t look
bad at all The RS-232 port it provide* connects to the
rest of the world using an industry standard DB 25
connector* not ihe CoCo 4-pin DIN counselor. The PBJ
unit uses the "CoCo standard" 4-pin DIN connectors; In
addition to the signal ground, transmitted daia T received
daia. and carrier detect IDTR) line available with the
CoCo's built in. or with the PBJ "s port, the Tandy product
also provides CD fPin 8). CTS (Pin 5), DSR (Pin ft) and
TD 8 (Pin 2). Thus, it represents a fuller implementation
of the RS-232 protocol* If you wish to program iin
application that will need to use those other lines, your
only choice in hardware packs is the Tandy product,

On the other hand* you can use your existing modem
cables with the PBJ unit And I know of no currently
ex is ling or propo&cd CoCo * oft ware thai uses the extra
lines provided by the Tandy Pak.

The Tandy unit provides about plus and minus 10 volts
on its lines. The PBJ unit provide* about plus

and minus 4.7 volts Both figures arc wtlhin specifications
lor ike industry standard for the RS-232 protocol. But
because the Tandy unit puts out somewhat more voltage
than the PBJ unit, it may he preferable tot those lew
applications where you warn io run 50 or more lee! of
RS-2.12 cable I must add that I know of lew users who
need more than 10 feci of cable.

Assuming one does not use the ROM supplied with the
Tandy unii T one has u 24-pin sockci io play with* The
PBJ unit if designed to support n 23-pin socket that you
solder in If you arc a hardware hacker, this means that
you can put up to a IftK by 8 1 27 1 28) EPROM in the
PBJ unit* whereas the ceding on HPRQM sire with the
Tandy unit us supplied is an 8K by 8 (687641 EPROM,
You really should «U PBJ if you plan io use the traces
provided for the socket. There arc a few del ails of how
to wire it that you should be aware of, depending on which
EPROM you want to use

Since many Radio Shack Computer Center employees
know little uboui the Deluxe RS-232 Program Pak. it V
rather hard io get good inlormation on how to use it
PBJ, in my experience, \s readily available to aid its
customers with prompt and knowledgeable advice The
folks at PBJ are always up lo date on what software —
both third party and from Tandy - works with their
products.

Hackers will be delighted to learn lhal PBJ makes the
uvaibhtr p.s n bllf bo*r(i «n, documentation rhc
price of this is $19. Bui be warned: While the circuit is
noi verycomplicatcd.andajl needed in for mat ion i> present,
this is no Heath kit! You need some experience in electronics
if you want to tackle the hare board. I buill iwo of them.
10 t know! 11 you do decide lo get the bare board, be
litre local! or write PBJ tor the latest revision of corrections

to be made to < he hoard, II you plan to wire uo ihe E PROM
socket, thi*. cspecialls importum. Purchase! s of the
assembled and tested unit need noi worry aboul thi*. as
all my reports indicate the units ordered have arrived In
excellent working condilion.

J\e saved the biggest difference for nearly lasL While
the Tandy Pnk provides only one hardware RS-232 port,
the PBJ unit gives you two lor almost the same price (only
SJll morel! One port Us addressed to the same place as
Tandy's (SFF68). and should run with all software dcuencd
to work with the Tandy unit. The second port is addressed
just above it starting at SFF6C To use tike Second port
as a printer port, youll have to alter Ihe wiring of the
busy line frnm your serial printer, as PBJ uses the M CD"
pin of the port as its busy detect, whereas the CoCo proper
uses the "receive data fine." instead. If you are using the
PBJ t'-C Bus expansion port device as well* PBJ ictU you
how to "Strap the interrupt lines" to use its device under
interrupt control. This option (not available lo Tandy
Multipak users) is useful to folks using a multi-user OS-
l ) -y^icm on the CoCo, but tor hltle else, Using this option
requires significant hardware and gciftwWRi experience. PBJ
nlso sells driver modules for the 2SP to be used with

Recommendations

h + s not an easy choice between these iw'o excellent unil*.
If you are sure youll only want one hard wart port forever,
i hen ihe Tandy Deluxe RS-232 Pak is a good choice, It
costs S1U less than the PBJ product and is available at
Radio Shuck. But. it" you are running OS -9, or if you're
a hardware and or toft ware hacker, you may do well to
get the PR* product, because of the extra flexibility offered
by having two* rather than one port,

All I can find for ;i reasonable price arc 2764s."

"Hew .i<imn l.i .;'■■..-,] up m> ri ms divt drives?"

**| sure like Spectrum DOS, but I cant run some machine

"How about new business?"

The chairman of the society , Bob Rosen, addresses (he
meeting

"I havt iht dm«er to oj these problems 24- Pin
■fi-Pin EIPROM Adapter from Spectrum Projects,"

Meeting adjourned so we can all go home and try the
new product

The 24-Piii/2tl-Pin EE* RUM Adapter is not fancy All
it consists of is tVftt tickets connected by a 2-ifttih pket
of ribbon cable. One male socket plops into the existing
ROM! socket in your disk controller, or your basic socket
if you wish. The other end of the cable has a 28- pin socket
that is adaptable to a 27 64 <SK v V). 27)28 06K x «J t
or 27256 Q2K * g| EPROM. Address lines, A 13 iwd A 14
are separated from the rest of the table such that i| an
EPROM greater than it K u used you can hank select the
portion of the HP ROM you wish to use.

What's the most practical use for this device other than
being able to use the less expensive 2764 EPROM? Wclf
Bob sent us a Z7I28 EPROM already mounted on the
board that noi only has Disk BASIC, but Spectrum DOS
H Mil. 1 hey are selectable by a small switch on the side
of our disk controller Another use that comes to mind
is to switch between basic 1J and 1.2, If you have access
to 27256 E PRO Ms you could select between four different
DOS*

The adapter kit comes with adequate instructions. For
a 2764 EPROM, no additional wiring is necessary. The
27128 and 27256 EPROMs require a small switch I two
for the 272561 to allow bank selection of the memory you
wish to use.

What if I want Disk basic and Spectrum DOS an a

If you've ever tried to make an adapter socket to convert

Inspect Your Programs
With BASIC Searcher

BASIC Searcher us a machine language utility that
searches through the tmes of your hastc program for any
selected string of characters, I he program can easily Hod
variables or key words and phra.^s. It allows you to find
your way through large programs looking lor key elements,

BASIC Searcher operates from protected high memory
and is called by a simple C*EC command. The program
searches tor the string of characters which you assign to
the BASIC variable SFS. You specify the hue to start the
search bv assigning the line number to variable 51.. Finally,
you can specify output to your printer by set ling SP'1.
or direct the output to the screen wtlh the default SP^O.

The program is supplied on tape for a I6K Color
Computer, Simple instructions show you how to load the
position- independent program for your particular memory
si/.c- The program is easily backed up to disk or tape, A
two-page description of the program's operation accomb
panics the tape.

Typically, you search a BASIC program by typing in the
simple commands *5Tffl*ffi: "SL^sfl land optionally

SP-0 or J) followed by E*£C. The program then scans
the bash test for thr first occurrence ol the "string"
characters, The program presents you with the BASIC line
containing the string. You then have the choice of pressing
'N* for the next occurrence, pressing l R' for the rest of
the occurrences, or "X" to exit the command.

BASfC Searcher has several uses beyond simply finding
a single word or phrase. The program can be used to list
all data statements in a program by using DRTft as a search
string lind pressing l R -\nothei viinpk' applicmor i> to
list all tfE J1 statements in a program as a means of
documentation.

The program does its job precisely as specified, It doesn't
miss any combinations of characters; 1 was unable to find
any technical flaws.

If you compose programs using u typical word processor
or screen editor* these search features may already be
available to you Rut, Sor many beginning programmers,

TALKHEAD And Real Talker
Reveal .New Dimension
In Voire Synthesis

By Kenneth D. Pcier*

Not only can your CoCq have a voice, but a realistic,
masculine face lo go along with ilf Colon* are has. an
animated "Talking Head'* program that uses high speed.
Hi-Res graphics to create a realistic audio-visual
simulation- TALKHEAD require* a MK CoCo and the
Colorwarc Real Talker voice pak* but the combination
may be hard to beat!

1 used both the cassette and disk versions of TALKHEA D
and found no difference other lhan speed of loading, Disk
mttH simply invert the disk and run TALKHEAD {a bask
loader program); cassette users CLpAO and rum t which takes
four minutes longer. The rest is automnlie. Three machine
language modules arc loiuk-d Jinti excvuivd. apparently
containing an Fnglish text -to- phoneme code translator* the
graphics for ihe head, the movement of eye*, mouth and
jaw, and the Col or ware logo, t rjlorware has its own unique:
audio- visual logo present ai ion that cani be missed! When
the Logo H linished, ihc I ll Kill 4 f ' &W .ippi-.n-- iftfl
says Talk he atl ready,"

At this point, " 1 :i Ik head" is ready for anything you care
io da next. You can experiment with typing various words
and phrases lor TuJkhcarf to say. write a program and
come hack lo I jl khc id. or toad programs from tape or
disk thai already ultli/c Talkhead's ability. A demo
program is provided on both disk and cassette version*
called Daisy. Remember the song "Daisy, Daisy, give me
your ,m>wer true ." 1 Well, I must have been hall crazy
lor running ihe demo so many times! won * *nnt!3V* ' gives
a fairly good icndttion at ihe song done by none other
than 1 alkhead himself ] was impressed by hot a the
audio and the visual achievement of TALKHEAD. It's
a simple song, and its not perl ecu hul I've heard worse
m risers, I he Talk head lace seems so lilelike I caught mywlf
following Ihe movement of his eyes and mouth just as I
would if listening K) u run her person. 1 he three-dimensional
quality graphics of the head combined with the appropriate
movement ol the eyes, mouth and jiaws during synthesized
•nfiecch is quite reulislic and well dune

Daisy demonsl rates what can he done with TA LKHEA D.
But more importantly, a look ui the program also shows-
how cosy programming Tallin tad can he in HASti , Two
new commands are available: SAY and PI I IK

SAY It very similar lo the PRINT command. Assuming
J ALKHEAD is Leaded ami ready. >mt c.rn sonpK lype
SflV kt frELLO, I RM HR. TRLKHERD" (and press
ENTER J. The screen immediately changes lo Hi-Rcs
graphics, filled with the life- 1 ike three-dimensional figure
of f alkhead. and he begins talking When he's through
talking, the graphics screen disappears and you are returned
to the text screen lalkhead always appears on the screen
automatically whenever he has ■mmethinii to SAY

Talk head speaks words or phrases in the immediate mode
or within a niogram. hither \\A\ r lour rules mom be
followed-

1) SAY must he the only command on a program line.
\o other commands, functions or siaiements are allowed
on the same line.

2) You cannot use siring manipulation, forexamplc SAY
{AS+HSJ, within a SAY statement

3] The length of the expression folio win $ the SAY
command is limiled to 212 phonemes or approximately
35 words.

4) Numeric variables musi be converted to string
variables first if you warn to SAY the numeric variable.

All the rules are simple to follow and pose no problems,
especially if you are beginning to wrile h program from
serai ch.

A ImEc exita work may he required, however, to convert
one of your existing programs for o*c with TALKHEA D.
Putting TALKHEAD lo a more practical use. I modified
a spelling program I had written using the Real Talker
with the old WJtWo-speceh translator software, in which
U=USR| All had lo be used every lime you wanted the value
of AS spoken. TALKHEAD uses Ihe new "enhanced"
software for the Real Talker, which simply use* SAY AS
whenever yon want to have the value of AS spoken. (This

software has been available since about May So,
il yuu have been using [he new. improved software for
/far/ Talker, you should find TALK HEAD can be used
immediately without any modification of your programs.
I, on [tit at her hand, had u- -.uhslitule the nc^ ruu.\
(SAY AS* for the old syntax (l-USR<AS|l Being in the
habil of writing programs with multiple command lines,
I soon found there was more to do than simple so hs lit ut ion-
After making the necessary substitutions, each multiple
command program line with SAY had to be broken away
from the seimcnce and n luted tm a separate hue hy ilsl-II
H look a little more work, but the endj roult wax worth
it-

My son, aged 7. had used the old spelling program fusing
ihc voice synthesizer without TALK MEAD) extensively in
first grade last year, He thought it was really neat to "see
someone" on TV giving him his spelling words! My older
daughter aged III, agreed, fcven my preschooler wanted
Talk head to do her spelling words, (she doesn't have any!),
Bui she is satisfied with just being able to type in letters
and words she knows to see Talk bead speak. She is in
speech therapy, so I hope to use TALKHEAD and the
fteai Talker to help her,

I spent a lot of time talking about SAY and the use
of one command line, but it's an area of interest that must
he considered more by those people who purchased Real
Talker* prior to May I , 19K4, and consequently might
demand mod tftcat ions to their existing programs in order
to incorporate TALK HEAD,

The second rule stales you cannot manipulate firings
within a SAY command, for example say a»+bs. You
tan issue t lie command SAY AS for any Value of the string
AS just as well a* 5av "This ts thf value: gf
Manipulations have to he done prior to wanting to say
the final result: Ci^s+fl* then SAY ct.

A single SAY line is limited to about 35 words or 2M
phonemes- When you think about it, that is anywhere from
four to six lines of text on a standard CoCo screen. If
that's not enough, you can use multiple SAY lines (many
program lines with one SAV command) or read in the
string variable within a loop.

SAY requires u string format, thus either a string vai table
or the lext ttilhin quotes is required. Therefore, il you
want to SAY a numeric variable (for example (he value
of X), you must first convert the numeric variable to a
siring variable using the 5tR* function in BASIC

I mentioned earlier that there were two new commands
to use TALKHEAD in BASIC, The other command is
PITCH. TALKHEAD was programmed lo "simulate"
singing "Daisy" by ihe use of the PITCH command.
HI It'll, which can be abbreviated PI on a command line,
\ itta i be piieh of the phonemes, words or phrase*, following
rhc PMCH command. The value of PITCH remains in
effeet until a new value is issued. If none is issued the
default value is I. Pitch levels available are U. 1.2 and
J. with zero being the lowest and three heuig the highest.

Iriiri^LH'J by ihc demo ion^. I just had m try my hand
at composing. WelL actually I didn't compose it t but I
programmed Talk head to sing it foi me. Ten to 1 5 minutes
of programming had Talk head singing "Mary Had a Little
Lamb."

TALKHEAD is really the "enhanced*' Real Talker's
machine Language tcxMo-speech translator combined with
ihe digitized Hi-Res graphics of the head, so up to now
anything other than graphics thai has been said about
TALK HEAD also has described the "enhanced** updated
ZQZ the. rainbow Mftf iftfis

Real Talker software A few additional comments about
Real Talker are necessary here to point out other
improvement* and addition! to it since my original re vie v*
of it appeared in the July Ti4 KAjNjtow.

Perhaps ihe mo.st noticeable tfilfcrcncc is the increased
ease of use for the BASIC programmer. There arc no DtFuSfl
or LISR statements to worry about. In making the Real
Talker extremely user-friendly, only one thing is left lor
you to remember: You musl uDBO and EXEC the Real Talker \
translator utility software first before you load another
program or »iart programming! The utility automatically
takes care of the rest, relocating itself and providing three
new commands for you to use in BASH : SAY. PITCH
and CONVERT, The first two commands have already
been discussed. CONVERT create* a stand -alone, talking
BASIC program that no longer requires use of the machine
language translator program. In other words, plug the voice
pak in. load your COWER Ted BASIC program and it talks!
All program Lines with SAY literals t e.g., 5«v "*t*olJu'M
in your program will be converted to stand-alone talk me
lines.

Among oilier improvements is the Phoneme lid nor now
tips as improved and expanded Help screen, and Ihe
translator now recoym/es and understands (pronounces)
dollars and cents whenever a '5' is encountered, finally,
ASCI TALK has been added to the Real Talker support
soil ware. This program will recite any ASCII file, from
a word processor ur a terminal program, line by line?

I enn'i think .H .mythin^ I d-'Ui like: or mould ;idU lit
I lie programs, nor ha^e I luund any taolts with the
documentation. Documentation lor both TALKHEAD
and the enhanced Real Talker sterns to be quite thorough,
I checked every sentence and tried every example Both
docom eolation booklets were extremely well -writ ten with
easy -to- understand explanations and examples. These
programs were a pleasure to use in HASH. .

The cassette version of both program* can be transferred
to disk should you upgrade to disk. Documentation gives
complete and clear instructions on l ransl erring to disk,
I actually did the transfers and ran TA LRHEAl) and Real
Talker from thai copy: it was no problem. Everything
performed as it had from the cassette version. For disk
users, thjs software will not run un J DOS. I had to switch
to Disk basic

If yoo have Colorware's Real Tulker and a h4k machine,
don't deprive y« uracil ol the exceptional graphics and
realism of TAI KHEAD If yon have the old version of
Real Talker, you might consider updating, with ih added
features and increased ease ol use I have all lour speech
units for the CoCo and definitely feel Real Talker has
become the simplest lo use in a hash - program — just
snv 1 'Uhatffuer ■ «. Ji's a fast r easy and convenient way
to make your program talk!

II you're looking for a piaelical reason to buy
TALKHEAD and Real Talker, my kids have all used the
program and feel they would rather have 1 alkhead give
them their spelling words and math problems than just
having to look at a screen without the tacet Were all in
agree mem in this household thai TALKHEAD is a good
addition lo the voice and makes a ureal head for the Real
Talker voice oak.

Music Library 200 A nd 300
Make Beautiful Tunes

Quotum: Doc*. «be availability of new hardware gene rale
software, or docs the availability of software generate
hardware sales?

Speech Systems h not taking a chance when it come*
to supporting their music-generating programs lor the
Color Computer. 1 hey have released two additional set*
of musical libraries to support their Mwica 2 system.

Recent reviews in THf KAtsaow have covered Mwka
2, the music compiling program, and Music Library fQQ,
the first release of musical compositions which were
eemr wiled dsnsfi the Coloi Cornpuia E he relent nt Mum
tJhrury 200 ami 3i\0 tremendously increases ihe amount
oJ pi -j recorded music which can be played on the CoCo.
or modified if one has the Musica 2 program,

First, I will briefly review Mwska 2 which was used to
generate Music Ubrar\ 200 and 300,

h alums v.Mi io create musiL'aJ Lompourions with up
to lour-part harmony (four voices played at one time).
The results are quite unlike anything you've ever heard
using the 5DJ*jd and plhv commands. The sound m the
songs is ouiic electric, similar to the tones created by a
Moog sy nth r siier, but abo reminiscent of a harpsieord
m a Wurltucr band organ without the cymbals.

The Color Computer and Musica 2 create the music
by generating a stream of numbers lhai the CoCo converts
to voltages through the sound port (six-bit digiiaMo-analog
converter). By varying the numbers and then the voltages
at tbc appropriate rate, a tone is produced through the
TV speaker. Pilch is varied by skipping a certain number
of values. This method of varying pitch makes il possible
to produce more than one note at a time.

Musical notes are displayed on the standard treble and
bass staffs as you create or edit them.

Music Uhxary Jfrfl and SOU does not contain the Musica
2 program. You cannot create or edit music with these
programs, only play the *elcclton* contained on thorn.

Musit I ibrdrv 2W contains:

Volume II More music from the '40s H "Mb,, "60s and
70s (39 minutes, 21 selections)

Volume 12 More music from the *7lh (43 minutes.
21 selections)

Volume 11 More 0WS$O Irtim the '(r!K and ^IK (43

minutes, 21 selections)
Volume M — More music from the '40s, '50s, 'bCfc and

*7tbf54 minutes, 21 selections)
Volume (5 t he Beatles (.17 minutes. 21 selections)

tmy penional favorite I

Music Uhran 300 consists of:

Volume 17 Nostalgia (42 minutes. 22 selections)

)9 selections)

Volume 19 - More music from the movies (40 minutes.
23 select ions 1

Volume 2t> - Music from the 'WK. 70s and TlOs (42
minuter 1 5 selections}

Each nl these musical libraries i* availuhle no cither disk
or tape The disk version is more desirable as it displays
ii menu of the awiiUhte titles and allows you to play any
selection at random, or program a series of your own
selections like a jukebox — except you don't need any
quarters.

The quality of the compositions range from OK to
fantastic, Clark Rulaford, who composed (or transferred)
these songs* using Musfea 2, obviously look extra time on
a few to maximize the results using the capabilities of
Musica 2. "Lady Madonna" and "Penny l-aoc," from the
Beatles disk, arc outstanding examples of the capabilities
of Musica 2. but "Norwegian Wood," also on the Beaiks
disk, drags.

To maximize the lonal quality of l he songs, it will be
necessary io add either an external sneaker to your TV
or purchase the Speech System-! Stefeo Pak accessory which
redirects the output ihrough your stereo. The small TV
speakers just don't have the tonal range to do justice to
the capabilifics of the Musica 2 system

A word Of warning. If vou purchase any of the Mu\U

Software Review J

Arithmetic Tutor Is
A Good Practice Tool
For Problem-Solving

Sometime* 1 view computer program* somewhat
analogous in television programs. A greai many of them
(mostly games) are for entertainment only. These are the
sitcomv variety shows and soap operas of computerland,
Applications! word preceding, etc.) are similar id TV news
programs .Finally, ed ucati o n al p ro grams f o r com pu I c rs ca n
be compared to educational programs on television: some
arc great and some arc very boring,

With thus in mind. I looked at an educational offering
from Computer Island called Arithmetic Tutor. This
package is primarily made for a classroom environment
and allows practice in multiplication, long division, factor
operations and the hierarchy of operations, Significantly,
the program provides feed hack not only in a "number right"
report, but also provides a diagnostic listing on various
aspects of the u pel at tun*, needed to complete a problem
rhc leaehci f 01 patent) can then help the child overcome
his specific compulation problems by checking oat what
problems continue to crop up on the report.

Prom a programming standpoint, Arithmetic Tutor is
thoogbJiuil] nuiJ-. rhc<twfcutiiJc»d o, T -rv..-.u/p ihE-.u^h
the problem-solving process, and is prompted at every
operation to tell what (he next computation will be. I do
have a criticism with Arithmetic Tutor in this area as ihe
program seems to he more interested in computational skills
than in process. That is. the program leads the student
through the process basicalh asking, for example. "flK.
now it is time to multiply; what is 8 times 77" instead
of "do 1 multiply or carry a number nest?"

On I he positive side, as with most good educational
programs made for computers, the nRFAfc and t i t.* r keys,
are disabled to prevent students from destroying records
of other vludcnis' work that hasn't been saved to disk.
Arithmetic Tutor also features a Help command to give
the students aid if they run into a problem area. The
program wdl automatically "help" students if they press
ENTtR without giving an answer. All this is recorded in
the report area so the teacher can check what areas the
stndcm needs the most help in later.

Although each session will hold information on a class
of only 15 to 17, the program will extend to hold more
students if disk space is available A password must be
provided to reveal diagnostic ml formation a« well as iv
start a new session One potential problem is no provision
is made if students have the some name. One student may
wipe out another's file if both are named "Ted," for
example. The documentation suggests using a different
name for one of the "Teds.*' My experience with children
is thai they aru \ct\ proud o\ tlu'ir names and tney don't
cart to change it for anyone (including a computerj!

The most important test of any educational program
is how well it works with its intended student. Here. I
must get back to the television analogy- The best
educational programs hold the student's attention while
they continue to involve the viewer in some educational
process. Here is where Arithmetic Tutor has a major

problem. After the initial interest in Ihe program because
of the computer gimmick. 1 lound children quickly discover
Ihe program is mostly drill and practice with tittle reward
and they lose interest. My daughter also complained that
it was too hard to do the computations on the keyboard
and video screen, and she soon resorted lo paper* wondering
why she was doing such problem* on a computer, anyway.
Hie .answer, ol course, is the diagnostic areas provided
for the teacher. The teachers, when using this program,
will have to be ready with some answers lo these questions
if they attempt to use the program in class.

A few Ojueslions are noi answered in the documentation
provided with the program, The author docs not attempt
to affiliate a grade level with the program. I suppose this
is not important as far as the arithmetic port inn la teacher

as students have goiten bored with I he "talking head"
approach to television and television moved to much better

B-XREF Is A Good Utility
For Any B ASIC09 Programmer

Anyone who docs much programming knows about
cross-reference programs. They arc utilities that take
programs and create such niceties as a variable dictionary
consisting of the location and type of variables, listings
of those lines pointed to by other lines by EOT Us and tiOSuGx*
and other useful references. These programs arc hard to
come b>\ however, since they are complicated lo write and
demanded only by the more experienced of programmer*

Since hasioh is relatively new, many companies have
not put much lime or money into the development of such
"risky" programs Fortunately, for those of us who program
in UASlow. one company has. It is Interactive Micro
Systems and their program is called B-XREF This is an
excellent program that can be used by anyone, from first-
lime users to old hands at programming.

The operation of the program is extremely simple; simple
enough, in fact, to warrant a one-page instruction sheet.
On the tact-filled page there iv a program description,
installation procedure, general instruction restrict ions and
a li*l of error messages.

Installation refers to placing the program where it can
be used. This is simply to copy the program from ihe master
disk unio Your working disk Venning can be simpler than
that, lo invoke the program is only a few keystrokes more
difficult than the installation 1 he command line that makes
B-XREF go to work 1st fc*r»f j«f>] [*\ \ i\ r i tai
(in-ru*? . . . ] [>outfij«j with the items in ihe square
brackets being optional.

All of the options preceded with a dash are called
switches. These allow for a customized output with as little
extra work by the user as possible, The switches are as
follows;

-f allows form feeds to be suppressed for use with printers
which do not accept Form feeds,

-w creates a narrow report, as opposed to a wide one,
which is especially useful for on-screen out puis.
I will present the listing of the source procedure:
otherwise the procedure is printed out before the oross-
re fere net nu informal! o n

Another feature of B-XREF is that more than one
procedure can be cr^s- referenced at a lime: simply add
the procedure name to the command line. In addition lo
multiple procedure names, the command line may have
any valid output path. This allows tor the output o| the
cross-reference to go to a file on disk, to the screen or
to the printer.

B-XREF has only two ohvious limitations, as is staled
in the documentation: The utility should be used only on
unpacked, emir-free procedures* If, however, it is fed a
procedure with a misspelled keyword, for example, there
is a good chance B-XREF will help you find the mistake.
The second restriction is there may be no mote than 500
total references This includes the use of a variable name,
procedure name or line number There is a note that if

ihe latter restriction is a problem, simply contact Interactive
Micro Systems for help.

Any utility would not he complete without error
messages. These are few in number (four) and cover
problems in opening files, lack of available memory, or
a full reference lable. The messages are sel (-explanatory*
but the documentation goes even lurther m explaining their
meanings.

The oulpui of l he utility is clearly laid out. At the top
of the page is the source listing of your procedure, unless
prohibited bv the -I switch, Aller ihuL. ihe program starts
lisiing all variables and procedure calls in alphabetical
order. On the left-hand side of a line is the name of the
variable, and on ihe right side is the type o I variable: integer,
string 20] > procedure name, etc. Un the nest line appears
Ihe line in which the reference occurs. The source program
lines need not be numbered, as in Disk BASIC, so when
B-XREF lists the source node u includes line numbers of
its own.

In general, I think B-XREF is a well-done an Ins which
will be useful to any programmer who uses BASIOW. Perhaps
it would be helpful lo have ihe program cross line numbers
as well as variables, hut since HAStc^y* docs nol require
them, this is a trivial omission, If only there were more
utilities such as this for other languages for the CoCot

On the first screen yaa dash madly about on four floors
of play, negotiating eight different stairways while
attempting to catch enough of Elsie's kisses [red heart*
that float from the lop of the screen Ho till in i tier >tl squares
on the Sailor Mans house. As on all of the screens, you
are vigorously pursued by none other than Bigfathadguy
who has fob own ideas aboul who ought to be getting Elsie's
favors. You're in danger of being eliminated until you can
-wallow a can ol spinach, which will ujvc you incredible
power over Your enemy . There's a punching bag at the
lop of the screen which, if your liming is exquisite, can
send a bucket down onto Bigfal bad guy's head - a feat
that will bring smiles to any onlookers.

The principle is the same on the second screen except
thai you are expected lo catch musical notes. Oh, yes. there
is the Otduglyscawoman who appears at higher difficulty
levels to hurl empty battles at you. You must punch them
to avoid being bounced into ihc water. The objective is
to calch enough notes lo play Elsie a love song, which
advances you lo the third screen where you must collect
etKWfch Letters (thrown by Flsjr's cries for H-E-L-P) lo
build a ladder to the crow's nesl where Elsie Is trapped.

One of the real delights ol the game is watching
Bigfatbadguy sail through the air. bouncing off the left
and right sides of the screen and then hearing the highly
audible splash "hen he hill the watei

Adding interest are the various musical interludes
between screens. Youll recognize and appreciate a (aM-
muving version of I he Popeye theme song. However* if
you lire of ihc music, pre** the 'M' key tu toggle tbc music
on and off.

By pressing the CLEAR key, you may select the number
of players, ihc level of difficulty (from I to 9), the number
of attempts, and the screen on which you wish lo begin.
Starting with any more men than three will prevent you
from entering your name on the high-score table.

After a while you forget the nnvelty of playing a 64K
gpiqti because the difference really isn't lhal noticeable,
which actually says a lot about the quality of the fames
already on the market for the Color Computer. However*
any feature you ever wanted in an arcade game is included

and number recognition. These programs are designed to
utilize the I o/n* fi/A by Spectrum Projects, hut donl feel
left out if you don't own unc. Alpftaiaik and Counwrn
work well without the voice.

In the program AlphatuJk* the child mutches Idler* on
the screen with keys on the computer, When run. Atphatutk
graphically displays on the screen a letter of the alphabet.
It randomly chooses .in upper- or lnwcrcaM; letter It um
haw the Voice Pak, the program will say the letter and
watt lor a response IL. allei iiu seconds, no kcj been
pressed, the letter will be spoken again. Jf the wrong key
is pressed, the letter will he spoken again and the program
wail* for I he correct key. When the right icy i* pressed,
a clown face appears, a snappy tune plays and the voice
tells them they are correct. The next letter then appears.

The colors and graphics arc nice in this program; even
those kids who were old enough to know their alphabet
forwards and backwards had fua with AlphataJk. My one
criticism, though, is with the graphics. Aiphamtk is all done
in low resolution graphic;,. This makes ihe letters hard to
read sometime*, particularly for those children who are
not very familiar with lowercase letters.

Countem is a Hi- Res graphics program. When ton, op
to 10 interesting objects appear on the screen. They may
be cars, birds, lamps, TVs or robots. The child counts the
number of objects and presses trie appropriate key. As in
Alphatatk. Cottntetn does not punish a wrong answer with
noises or flashing display*, but simply waits lor the cor reel
response. When the right key is pressed, the screen changes
to a pair of robot-Like creatures who shoot a laser back
and forth There is a muskal tunc and a >pnkcn. reward
The nc*,t group o! object* then appears on the screen. This
program reinforces number recognition as well as counting
skills.

Both of These programs arc simple enough for pre-
schoolers to pi ay and enjoy without much adult intervention
Children it* young as 3 and as old as 6 had fun with
Couniem. Alphatatk was enjoyed by all who were ready
to learn both upper- and lowertia.se letter-*

LIZPAC: An Extensive
Stalisltcal Analysis Package

By Frank .1. fcistr

A variety oi statistical packages have existed for
mainframe computers for quite some lime, Tney are an
invaluable aid to sckntisls and engineers, and give these
people l tie a hi lily to pul observed data into somt
meaningful lotin and. quiir often, display [he resuhs in
graphical form, These packages offer a number of different
routines or programs, and depending upon what the
individual desires, dict.Oc which ol ihc routines he would
use. Sometimes more than one routine will he found Q&Ttll
wis! at other times, ihc data output from one may be fid
into anolhet to produce Mill another set ol data. Whatever
the desire of the user, the bottom line is thai he has at
his disposal a act of routines to help analyze data sets and
reach a conclusion without Uie need lor I nog und lengthy
manual calculations. To anyone who has gone through
such manual calculations, you know what a pruhlcm ii
can be.

What has all lain got to do with LtZPACmd the Color
Computer? Well, a statistical analysis package has come
to the world ol the Color Computer, Those of you interested
in frequency distribution, regression analysis and so on,
this is what Lt/.PAC is all about. | am not a whir, at
statistics and cannot begin to determine if everything is
present that would be desired However, t can attest there
is an awful lot offered by I his package (hat should more
than delight the heart of l he user.

The programs come on eight 5'i-incb diskettes thus
is correct — there arc eight diskettes lull of programs and
editors. The documentation is contained in a standard
three-ring binder and consists of around 140 page* of
instructions, and approximately 35 pages lit printer listings
of individual program runs. The last section contains the
instructions for SHOWPACK LO which will help create,
label and edit Hi- Res graphics screen displays.

UZPA C consists of SM siuiistical and file management
programs. LJZPAC programs arc loaded by a single
keystroke from the control program, Minimum requirements
for Ul PA C arc 32 K of memory. Extended b*sjc, » printer
and at least a single disk drive. According to the
documentation, LIZPAC can be used by individuals who
have only a superficial knowledge uf the use of computers.

The excellent use of menus and screen ptompts are enough
so the user need not worry about data files, etc. Many
of the programs ask if data file* are to be constructed
during the running of [T11.1 progiani 1 he usei is lhrn
prompted how 10 enter the data.

The doc-omen 1 at ion also states UZPACdvc* not assume
the user has an extensive knowledge of statistics. However,
the user must be sufficiently familiar with the statistical
process ;oul terminology as, id he able to provide
appropriate responses to LIZPAC' queries and prompts:
if you dunt know anything about statistics, this package
is not for you. U7.P4C k written entirely tn basic, and
can he listed und modified should the user feel the urge

in ill* so

LIZPAC is broken down into five packages. The
following is a brief description of each of those packages.

Package A — ( ore Package

Data file Ad mi nisi rat ion Has a complete editor for
editing data hies, utilities to perform sorting, merging,
deleting from and adding to data files.

Descriptive Statistics Consists of one-way frequency

Comparison of Means Comparison by t-tcst. Schelfc's
lest and Tukey*s test, examination of means for polynomial
trends, parti tinned AN OVA tables and standard A NOV A
r-0-.lo.

Regression Analysts - Mass production of Pearson's
Special packages for polynomial regression and
exponential regression analysis,

labeling LIZPAC graphs saved to diskette.

Dataoack Converts ASCII files to LIZPAC files or
converts LJZPAi files to ASCII files,

Package R — Factor Analysis

Programs in this package provide for preparation ul the
raw data lite and the correlation matrix, extraction of the
principal components and estimating the principal factors
by iteration. The rota u on methods available arc Quart i max.

the standard manner

The UZPAC package is ijuilr impressive. The authors
have gone through quite a bit ol work to ensure the
programs run as they should and have added some very
nice utilities. The EDITOR is not a Tttvwitor-64 t but is
functional and docs the job very nicely. SHOW PACK is
another good example of the type of utilities lhai were
added: it will lei you plot your dala on the screen in the
Hi- Re* rn^dc You e;in tht:ii labd the charts graphs, etc..
however you want. The entire screen display can be saved

and. if so desired, can become a part of a slide presentation.
The programs themselves are quite concise, and from the
very simple icms I ran. straight forward to use. Every
attempt has been made by the authors to make the programs
usable by someone other than a computer expert. One nice
fcatuie *>f each data run is the ahiliiv [<i add to ihc output
listing, the date ol the run and the person performing ihc
rwn\ Thai appears on each printed output even it it goes
tn the disk.

I am nol a statistician nor do I perform the type of
daia analysis in my everyday job that these programs
provide, but I do know that UZPA C is not for everyone.
For those who need to perform data analysis of any kind,
be it social studies, agricultural studies, scientific studies
or any type of dala manipulation, 1 think this is the set
of programs for you. The only hard part is getting the
dala on the disk for processing. A utiliiy called DATA PACK
will take a UZPAC file and convert ii 10 an ASCII file
orati ASCI [file to a UZPAC V\k So if sou have a ler nun.!
program and your data is on some other machine* you
can dial into thai machine, access ihc fUc, and UZPAC
will do the rest,

Mike UZPAC tl is well-done and Che documentation,
though not for the beginner. \s also well-done. There afc
eight disks full of programs and sample data files. Again,
this package is not for someone who docs not have at
Icasl a good general background in statistics or data
manipulating, it assumes a knowledge of certain skills is

Be A Battleship Mate
In Talking Shiphuni

Jf you're looking Tor a version of "ILIccirome Baltics tup"
for the CoCo, your search u over Talking Shiphuni is
a ilnucpc |jainc rc^| lining 32K Lit lend cd hami , tmr
joystick and QW player For the fees! cffccl. Spectrum
Projeci \ t <Hi r Pak with Del Software's f ramhtc program
should He used in conjunction with the program. Shiphunf
i an he played wit ho in voice, but ii s much more interesting
when CoCo talks to you.

A ihon instruction >fieei included which letis you how
to bad in the program*. Shphwtr is supplied on easscMc.
hut can be easily saved to dhk or another tape for a spare
copy. Before loading, make sure ihe CoCo is off, Ihen
insert the VoUr Pak cartridge. Next CLOftD' *shiphjmt 4 '
run ii. You arc I hen asked w Po you Wiim nic la talk?"
If yes. pul the Translate program into the cassette player
and press + Y'(o load and execute. ( Translate is the machine
language icxt-tivspeecri program j Before the game begins,
instructions can he read and; or heard.

Game pint: is similar to the pegboard game "Bat lie-Ship. "
One big difference between the two is that the player does
all the guessing in Shiphunt as to where i he computer hides
(he ships. The player doesn't have ships of his own lo deploy
for CoCo 10 find. My attention span would have been
longer if this capability was included

Ai the *tari, ah 12-inch Hi-Res graphics grid a drawn
on the Icli nE your screen with 71 shots available, I prefer
to use the keyboard to place the cursor in the spot J wish
to fire upon. However, response li me between the keystroke
Until i be cursor moves from bluck to hi nek is slow and
can be aggravating The right joy-stick musl He plugged
in 50 the cursor doesn't drill across the screen, h can also
be used tor movement, but ihe keyboard provides beticr
control.

The object is lo sink alt five ot Ihe computer s ships
before your shots are gone. Five hits are needed to sink
the battleship „ four for the cruiser, three for the submarine,
i wo lor ihe destroyer, and one for the frigate If you miss,
a green oar appears in the block you last shot Hits are
i h p tycd as yellow burs. Indicators at the right of the screen
list how many ships* and which ones, have been hit or
sunk, and how many shots are left.

Throughout i|*c game, you tan hear ihe capiain giving
orders to his crew. "You scrub ihe deck," "Ijoad Ihe
cannon," and "Get ready to nrc," arc a few. The captain
will also talk lo you, saying things like if Ptease« can't we
talk Ihis over?" Some limes ilS hard lo undci stand what
is spoken, but if you lorn the volume op and listen closely,
I he sentences make sense Anytime during ihe game, hilling
T will turn the speech, off. This will speed up execution
of the program, but it s rioi as entertaining without speech

There is no big finale at the end, When someone win*,
a test display of the grid is flashed on ihe screen ior a
few seconds, which shows where the remaining ships (if
any | are and what your score is.

Talking Shiphuni is a good game lor the younger children
and inexperienced name players who don't want a lot of
action. If you plan lo purchase it, make sure you first
have the fWtv Pak wiih Del Sof I ware's Trawtaic program.

Gamble Casi no-Sly le
With Bttkersfiehi KENO

Anyone who has ever visiicd one of our gambling mcccas
liLt-s probably played keno, Yuu can't help nut playing u
because it^ everywhere; in the rcstta urant*, lounges* the
casino game areas, even in washrooms

My favorite casino hast a great S.I steak and eggs breaklnsi
in IK diriiiiL' liall tit i ht- middle .'I (he tahtcv u?rh rhv vdt
and pepper ^takers are keno irays filled with forms and
pencils. The roving game steward is. only loo happy 10
pLk up your game ticket and net at your table. Thai S3
breakfast usually winds op costing a lot more after losing
a number ol kenu games.

BakvrsfieU KUNQ comes on cassette and requires 32K
Extended tiASU and b not copy -protected. After you run
the program/ your eyes arc treated to a Hi-Re* graphics*
display of numbered Ping-Pong balls bouncing around a
glass jar just like in the casinos. An attractive keno board
fill* ihe screen thai serves as both the yd me ticket and
the name board.

The program prompts you for the starting bankroll thai
cannot exceed SLOOO. The maximum bet allowable £*$9 k $99
or k ■>>. if: pv rid me. i>n hov much you IWTO* tftft I' be program
keeps track oj your bankroll, bets and payoffs.

Next, you pick how many numbers will be played with
o choice of from one to 15, You can use the left-arrow
key to go back and change a number before starting the

actual name j nav leauire. I he computer ihen selects
15 numbers at random and more times than not, they are
not the numbers you picked (just like in the casinos)! I
played over 100 games and only won once, which made
mc wonder if ihe game it rigged. This theory was quickly
blown to shreds, however, when a Iriend of mine who does
very well in casino keno won a Jot more than I did using
this program

When you run out ol money or eorne vers close to
wiiimnn. any one oJ a number ol humorous phrases is
displayed, such as "CLOSF BUT NO nCSAR."

Baken field KENO can be considered lo be both a home
version ol the game and a serious simulation of the real
thine, except lor one detail. Only one game curd enn be
played per game. I would have liked to have been able
to play several cards at once or play along with friends.

I could find no bugs in the program, and great care
has been taken to reject incorrect user response.

I be documentation consists of one typewritten page thai
IS mainly a puyoir chart with simple instructions to run
Ihe prngrant. Tvcn if you have never played keno before,
the documentation is sufficient to get you goinp and
underhand all ihe learurrs and "nti-wis

Hakvtsfu td ht \ t) is Inn to play and is sure lo please
those who can't afford tn drive to Reno every lime the
keno bug hiles. t-ven though I kept on losing my bets,
it ^as hard to stop playing (just like in the casinos)! Nothing
else is requited lo use ibis tine program except the feeling
that "Lady Luck" might be on your side today.

TEXT Teaches Valuable
Lesson In Word Processing

What could possibly be i merest ing abowi a program
culled TEX 71 h it something you read with or write with?
H must he boring with a name like thai.

Thm \ whai I thought I was wrongl You Ye noi goi ng
id he ra//!cii unci da/? led with lights and colors, but your
child will receive u valuable lesson in a pre- word processing
activity,

/'/■.' V7~ allow* children in type, tdit and fornuu words
and sentences on the video display. The letters are targe
and appropriately sized for young children. Fach line holds
13 characters and each screen. >even Sines The program
can hold up to three screens of in format ion in memory.
The cursor ha% loiir-u^y nondotrLictue control; U"U in
noi destroyed when the cursor ts moved Paging is
controlled hy placing the cursor in the bottom or top currier
and pressing the right- or left -arrow key. When paging
lo I hi? oc\l screen,, a brie! waiting period is encountered
whj Je p aging takes p lace This wai i wou Id be inco nsequcntial
for small children.

Whai would n word processing program he without somu
filing and retrieving capabilities? TEXT has these, also.
Pressing the shut and left -arrow keys at the same time

invokes the uldity menu From this menu, saving and
retrieving from disk or tape is possible. Printing the file
is also an option mi the mil My menu. All printable keyboard
tharacicrs are programmed into the TEX 7 program

TEXT would he a tamable tool for schools and parents
who desire an mlroduclion to word processing for children.
All the terms and conditions o( t i sophisticated word
processing program can be introduced and demonstrated.
Used properly, a child would benefit greatly from this
program

There are a few problems with the program that need
to be addressed The lollowiog enhancement suggestions
would add to an already fine program. The program is
written in bask and the hrf Ak key is not disabled. This
is an absolute must for programs thai are to be used by
small children. No recovery procedures are built into the
program. Another feature that would be nice ii auto key
repeal This would provide an even more realistic word
processing experience. One last enhancement would be
improved documental ion. It a program is io be used with
young children, ideas and projects should be offered for
the parent ut leather FE XT documentation is one copied
sheet with instructions

In summary, TFXT\s well-constructed and bug-free, it's
a lesson for learning thai should not be missed?

(For information on Graphkom see l»t KAtNHOW, April
I95W \ Shan* requires a 32K QoCo and one disk drive.
Use of up to four drive* is supported by Shrinx ;

A small, well laid out upt/aiurs m nuiai at in m panics

was up and running quickly t found one small problem
in ihc hoot portion of the manual, it stales: "Put the disk

push the l"N 1 1 tt key. Drive 0 will start and you will be
greeted with the Shrinv menu." the did m<i w<>rk u^ing
Ihc standard Disk basil I had to type: blin* ■ shrink* *
then press eivti-k,

Following is a list of Shrinx commands:

J = Disk Directory Typing a Twill list .ill Ihc binary

L ~ Load — Typing "L" allows you to load binary picture
files from a Rodin Shack formatted disk.

W = Write — Pushing 'W permits you to write a picture
to a Radio Shack tut matted disk.

P - Drive - Typing *D' allows you to change the drive
that is currently being accessed by the Loud. Write and
Disk Directory commands.

E '* Enlarge The Enlarge function divides the ictccii

S " Shrink Pressing *S* scales the original picture
into lour quarter-frame pictures hy deleting horizontal and
vertical lines Fach quarter-frame picture is unique because
dillcrcnt lines are removed from each frame.

V * Variable Shrink - You can scale a picture to a
desired size using the Variable Shrink function.

I = Transfer The Transfer function allows you to
save a picture to a Graphtcom picture disk.

G ■ Gel - Using the Oct command permits you to
load a picture from a Graphkom picture disk.

The Shrinx command structure allows you to easily
transfer picture*, from Radio Shack formatted disks to
Graphkom picture disks and vice versa I found the Shrinx
program \cry user friendly, When used in conjunction with
Graphkom, Shrinx can be an exceptional tool for the
programmer artist and or novice.

is used in the Disk BASIC version, but unfortunately it is

If you do not have a lull-screen editing program, yoc
should consider Radio Shack's version before you decide
on one. It is a good version with an excellent instruction
manual. The manual's last ihiee pages are a glossary nf
the 7y££/}/7~ commands, and after you initially go through

requires the OS-9 Operating System, 64 K RAM and one

The transfer is both fast and painless. You may iransfer
both texi files find programs saved as ASCII files irom
one operating system to the other, however, TRSCOPY
moves the files without modification; control and oiher
special characters arc copied, hat not translated li yi-.n

appear as an ASCII file on the disk. Ynu will frafVC io

at least, remove the PROt bIHJRI line at the lop of the
program.

Again, if you do not already own a fullscreen l Jimi
or a TTTSCGPy-lypc program, these programs deserve your
attention. Radio Shack did a good job developing T/S
EDIT and TKSCOPY and more support seems to be
around the corner II you do a lot of debugging, but are
not sure you need these programs then a slop at your
local Radio Shack for h demonstration may be in order,

Omega File: Good
Management System With
A Price To Match

By Rubn-l Foilr*

(Jfm'Xu Fib is a single debased tile management system
which doc* not require 64 K and allows the user to handle
files with retards in one file as large as 4.0K0 character*.
Just so we are alt talking about the same thing, a nrcw^
i» a group of data arranged in data Fields or lines, and
ii ft h- i- .1 fuLlcctinn of These records,

This program is designed io pcnniL the user to create
individualized records with up to 16 data fields and each
field may he comtmeied to hold from one to 255 characters.
Since this is a single disk system, ihc number of records
thai tan he handled by the program is dependent upon
the size and number of fields selected for each record. For
example, if the user wishes to create | file with records
which, each use the maximum 10 fields and each lie Id m
the maximum of 255 characters long, then this Hit would
he limited to only 37 records, Hut. a file with records limited
to tO fields of 20 character* each would allow for about
7SW records. The urinal file size (e.g., number of records
in the file]! is limited by the storage space available on
the disk in use,

The program allows Tor sorting of records and a "iert
i Ml" is created Thus, if the user plans to store close to
i he maximum number ot records on a single disk, some
planning is needed to leave room on the disk for the sort
Tile. The user might store several small files, with sort file*
lor each, on the same disk with a little planning. However,
thou Id it happen that the user didnt do the homework,
i he program will flash the "Disk storage is getting low""
message on the screen belnre more Jut:; ran he entered

The hardest pari of creating a file is the thought that
need* to he put inlu deciding wlui the records should hold
To get to the I ask of structuring records for a file, select
the Create option Irom the rile Maker Menu. As noted,
each record may have up lo 16 data Fields and each of
those fields is to he labeled (up to 10 characters long).
The usci also sets the length ol the data field (Up to 255
maximum}, in effect, this creates a tcmpluic for each record
to be m the file.

A Her the form is designed, it is just a matter of i> piu^
in the proper information for cadi record tn noisti net the
file. The program author has provided several good
examples it* follow in setting up the record format and
a ho has provided several worksheets in the back of the
manual to facilitate formatting a fife.

When the user completes the designing of the record
format or wishes to abort the efforts by hitting the *{Sr*
key, the program returns to I he main menu From the
main menu, the user now has the choice of "using" a file
and. once I he title is entered, the Fife Maintenance Mena
appears.

To speed up operations of the program, the program
author has used the I why* mode, which jumps the program
to the next line or option when the designated number
of characters is reached or kmi-k is nil, After the first

eight characters of 3 filename an entered, the program
goes tight to the Field Maintenance or working menu. Also,
while entering the data into the tlala fields of the records,
when the designated number of character* i$ reached lor
that field, ihc program jumps to the next djia field. 1 Mi-
ls fast, but it can cause problems Tor an inattentive user.
However, the user may go into the Change option and
correct the error

At least one problem the user docs not have to worry
ah Liu 1 is the saving to disk of the data. The program takes
care of saving to disk n\ i\ needed. (But he careful: Upon
ending the session, when ilie program ask* if you warn
to "Save file*** anawcr *Y* or the program Will kilt all ihc
rccoTds in the file!)

Another speed up method in the program allow* ihc
user to repeal an entry in succeeding records by hitting
the key while in the data Held The data field will
automatically be filled with the information located in ihc
same dulu Held of the preceding record Repetitive entries
are a snap.

The Maintenance Menu now provides the option of cither
adding records 10 the file, changing information in
indiwdutt! records, viewing records in sequential order, or
calling up a single record by its record number. If desired,
deleting any record is possible: however, the record is not
actually removed from ihc file, rather the first line of data
in replaced by an '<£>* and the rest of the data fields are
blanked It appears that once 4 record is created and then
"deleled," it still takes up space in the file and this space
cannot he used again- IT>us h the user should think about
using the Change option to save storage space on ihc disk

The Sort Option can he used on any one data field within

it record, and the tine or data field selected wilt be used
K the key for an ascending order "sort file." Only one
sort file per file is accepted by the program. If the user
changes I he *ort field, the program will overwrite the old
sort file. A* nnled earlier, if a file is getting close to the
maximum number of records the disk can store, there may
not be room for a sort fdc and n DF Error will occur
causing the program to hang up. However, several short
files with sorl files can be on the same disk, depending
on storage require menu of each file. The size or the sort
file is direcily related 10 ihc number of records in the file
being sorted as the program list?, the order of the records
by their record number in this sort fde.

The last option in the Maintenance Menu is the Prim
routine All printing functions are -,ci lo the C0C0 default
WXf Baud. However, the user has the option of printing
to un HO- or |}2-eoiumn primer.

The output 10 Ihc printer allows for many configurations.
Hie u.ser iua> select 10 have ihu material primed with or
ttltltOtf a heading, with or without records* numbers, all
or only some of ihe data fields, everything printed one
line under 'he other, or each data Held following
hon/onlalk the program also provides for a priming of
only those records that match the first 25 character siring
m a selected data field. The user may also decide margins,
both lop and bottom, and ihc number of lines between
each record The order in which the data fields arc printed
out is up to the user The records may be printed out
from the file Of they were entered or printed out from
the sorted file. Once a print formal is set* all the variables
are stored by the program. If the user wishes to change
any ol the optional ways of print i ng nut the file, the program
provide* thai option, too!

The program's biggest drawback is the type used to print
ihc manual: h is a very condensed type {print size one
might expert on a legal form!} Tlie material is presented
in a logical order and includes samples 10 follow to get
a user started It would have been helpful if the program
author had included information on how to figure the
amount nj disk storage required by the record size and
number of records, ll would be even nicer if ihc program
would read the disk and then, based on the record size
designed, display on the screen the approximate number
of records which might be stored on thai disk.

The program makes mv of sound to assist the user in
the prim option, but the use Off a beep when the iunvr%
mode jumps to 1 he next line would be very helpful. If the
user were copying data from a list and not watching the
screen all the itmc, the sound would be an alert of the
hue jump. Also, the use of sound with the '"Disk storage
is getting low'** message would be help fid or better yet,
at least Weep the message on screen until the user hits ENTfcH,
again Should the maximum disk storage space be reached
and Ihe t^tr does noi see the message, the DF Error may
occur and ihc program crashes. As noted earlier, if the
size of Ihc record is small, the rmuimum storage space
may never be a problem. One option some other systems
have, which would he a nice enhancement, is the "Reverse
at Comma" option,

A manual printed tn a more user-friendly type st/c and
a few more "beeps" al the right lime would be the only
improvements needed to make this excellent program ever,
better.

Create Graphics Masterpieces
With Rembrandt

By Bruce Kolhermel

I really like my Color Computer. However. 1 sometimes
look ai [lit capabdmc* ol ihe newer meg a -buck computers
with more than a little jealousy. For example, the
Macintosh computer has graphics capabilities that make
mca little green with envy. Admittedly, she Mac's graphic*
are monochrome, but they sure arc nice

Well, I'm pleased lo report that a program has been
released which gives advanced graphics capabilities to the
CoCo. Appropriately called Rembrandt, this program
Jill cm* the Color Computer lo:
— Draw lines, circles and ellipses
Fill in ureas ipaitii} in 16 patterns.
Repeat a pattern trom one part of. ihc screen Ui
others (Stamp).

Enlarge u portion of the screen and edit thai area.
Pul IcM oil the graphics screen.
- Save and loud pictures,

Rrmhramit % graphics utilize the highest resolution PfffiDE
4 screens with "artifacts'* to produce more than the two
color* Radin Shack siiyi you can have in this mode, A
small BAStC program is included to ensure that ihc Hi-
kes graphics colors are correct.

There are three operation modes in Rrnihrandi , These
are the full-screen line-drawing mode, the menu, select
mode, and the close-up en Nit ye edit mode

The full -screen 1 1 tic-drawing mode is used to create the
general foundation or framework of ihe picture. The menu
modes allow you in select a particular function or parameter
by presenting 3 list of options. The main menu mode has
several options, all other submenus are selected trom the
main menu.

I he enlarge edit mode allows you to ^hlowup" a portion
ol the screen lot detailed close-up editing It is used to
pui the finishing touches on a picture you have created,
or to natch Errors that would be loo tedious to correct
in the full -screen mode.

Almost ull functions con be control let! by the right
joystick. The only lime the keyboard needs to be used u
to enter tc*t or enter the name o! a picture to be saved.
In operation, after the program is loaded, you are greeted
with the main menu. At this point you have 12 options:

W htc, Black. Red, Blue. Paint. Circle. Screen Modes.
Stamp Function. Enlarge/ Edit, I/O Functions. Initialise,
or Return

The first four choices change ihe current color, Thi
current color is shown with a dot nc\t to it.

flawing lines In dime urmt- in ihc fuU-*Srwil mode 1 to
right joystick controls the position of the cursor which
ii surrounded by a ho\ in the screen. Lines ore drawn
by tapping ihe joystick button where you want the line
to start and then moving and lapping the cursor where
you want the line tu terminate.

Circles arc drawn by lapping the joystick at the center
point of the circle. As you hold the tuition, a circle with
an increasing diameter appears lapping Ihe button a
second time freezes the circle. Moving tJie joystick left or
right, up or down, while ihe circle is being drawn turns
o into an cllipsc.

Painl allows you to fill-in any ipeeificti area with up

22$ THE RAINBOW Mjrth 198*

to In colors und put terns. A nice feature with Rembrandt
is ihut you have the option to erase your last command
by pressing the 1 1. 1. AX button.
The lust graphics option available from (he mam menu
the Sump lumtmri I hi* i»pin>T> ,iHi>ws vou lo sirled

to duplicate whatever is in that box anywhere else on the
screen. Option* allow you So place this M.imp on lop «if
or under anything on the screen^

tniiiali/e wipes whatever picture is in memory by painting
the current screen in the current color With many of the
options, siibmcmtsjjivc you additional options to customize
your creation.

Text can be added to your drawing by pressing 'X' on
the keyboard A red crap hies cursor then appears. By
pftfttSllg ihc arrow keys, graphics can be placed anywhere
on the screen, True lowercase with real descenders is

possible by pressing stm t und 0: this acis a* a toggle
between caps and lowercase und all capitals.

Ihc mode uliich make-, Rembrandt very usable for fine,
detailed drawing is the enlarge edit mode. In this mode,
you can select any portion o| the screen so ii can be enlarged
12 times lor detailed examination and editing Fach 01
the 49.152 pixels (dolsi which compote the screen can be
individually colored to add detail or correct errors. You
always have a reference as lo what this enlargement will
look like in the actual size version, because beneath the
blowup the area being worked on appears in normal

The detail lhai can be obtained in this mode is unite
impressive, although filling in ihc screen one pixel ul a
time is quite time-consuming, but with ihc tools offered,
very impressive graphics can be created.

The only shortcomings 1 found were a complete lack
i>1 am tcltrenee in Hie tape \cr>mn reyardinc- fn>\v youi
completed masterpiece can he printed. Whal good is
spending hours creniinp ihe iiltimmc Color Computer
graphics :t it can «itil\ W displaced on a screen? lis Ljuile
difficult carrying your CoCo and TV around to show vour
creation

The other objection 1 bad is the reaction of the cursor
when it is being controlled by the Jovsiick The block
surrounding thecurtnr moves in Ihe directum of the cursor,
but not at the same speed As you mnve the cursor, lor
example, to the upper-left comer ofLhc bos., the bn^ dull-.

in ihut direction, but at i different speed- This results in
a lot of wiggling und overshooting your target on the screen.
It Talics n lutle gctiing used to. It would be nice to have
the option of moving the cursor with the arrow keys as
well as the joystick.

If you have a MK Fx tended basic disk system, an
advanced version of Rembrandt Ls available- The main
.ulv .iniaye ul ihv oVk Msiun is ihi ahdity to rapid ly save
and access picture*. Com pic led wrap hies are stored on the
disk and a small iik management program i* included [<i
simplify storing and recalling your masterpieces.

The good news is that the disk version, being a later
release, includes brief instructions on how 10 use a screen
prim program and a dot matrix printer to make & hard 1
copy of your creation. The had iieus is thai Ihe instructions
don't work. Completed pictures have be to loaded into
the computer using the BASIC command lOAON" ■ t ilurmnttf
REtV '. rather than the *.rjAu" * f i liiniiwPEfl* ' instructions
given in the manual.

The screen print shown is a greatly reduced reproduction
created by one of the demo drawings supplied uith ihe
program. While it dues not show the brilliant colors
obtainable with Rembrandt, it gives ynu an idea of ihe
fine detail available when using the program

If you are "into" computer graphics, Rembrandt seems
tn maxmii/e ihe capabilities ol the Color Computer With
it. you are able lo create graphics and pictures thai are
otherwise impossible according to Radio Shack documcn-
l at ion. Suddenly that Macintosh doesn't look as good
anymore!

ihm > Forget is a disk -based program Irom Compuierwarc
that allows you in construct and maintain an appointmcnl

I J I urn on your Color Computer , monitor and printer

2) Put ihtr program disk in Dnu- f».

,1) Put a blank formatted disk in Drive I

A) bun "fttriEnBEe"

5) The program will ask you Ion an excellent Hi- Res
screenl to say which drive has which disk. Jl will Ihcn
uxk you whether you arc going la use keyboard arro^
or joystick

6) You will then he gftttf) u menu. Choose ^Build a
new calendar year."

T) Choose i he month iind year where you want Ho begin,
the program will draw a picture of that month on (he screen
- one ol its talents

H) Move the cursor to a dale and enter. You will be
given a ~puge M with icons tliltle pictures - the latest rage)
at I he lop. mnm io enlcr two line* in a section called
"Special Occasion*." line* wiih hour Headings to enter
appoint mcntv. and a .section labeled "Memo*"

9} Say; on a particular day. you have a dentist
appointment ui 7:00. Move the cursor to the keyboard
(com FMtK (to show that you are poinu to type in
something), move the cursor to the "^iOO" line. l\pe in
-dentist" and enter Is this das locA birthday 1 M^f ihe
cursor to Special Occasion and type "Joe's birthday,'* Now
move the cursor in (He Memo section and type "pack up
cake at bakery lor party" and enter

U\) li that aJ) for this duy right now? Move the cursor
lo the disk icon and enter. Drive I will come on and save
ihe data Move (o another day. or another month, and
continue for as long as time and patience permit For
example* £0 through the year and pot in all birthdays,
anniversaries and holidays Put in the dates of conferences,
vacations, etc. Just remember to save each day's entries
lo the disk before you leave that "page"* or your entries
will be tost.

I i him- rhe appointment calendar, repeat the steps above,
except in step 3 ynu will put your calendar disk in Drive
I You can now call any month and date, add other entries
and look at what is already entered.

Suppose you want to know what is on the schedule for
today. This is ihe sequence: Turn on your computer, load
the program disk Jlld calendar disk, run the pui^iam, tell

f!| OPTION 4

it the program is in Drive 0. thai you are using joysticks,
that voti wani February I9B5 nod that ynu watii to hoc
ihe Nib Do you want to have a hard enpy? Move ihe
cursor to the printer ieon and enter It will prim out just
what is on the screen. You can also print out a week's
calendar 7 days from the day you are in.

Another option is lo print oat a blank calendar for the
selected month to use as u scratchpad for appointments
lo be entered on your calendar disk al a convenient time.

Suppose you changed \our demist appointment to 4;I)U.
You can move the cursor to the s 00 line and enter, now
move the cursor to Ihe scissors icon and enter, and then
move the cursor to the 4:00 line and enter. Or, you coukl
move the cursor from the scissors io the trash can icon
and enter. (1 is now deleted Did you change your
appointment to Thursday? Move the cursor from the
scissors to the clipboard and enter. It is now saved. Move
the cursor lo disk and save Ihe revised day. Go back to
ihe February eatendar page and select Thursday. Move
the cursor to the clipboard, enter, move it to the lime of
>our appointment and enter tro to the disk icon lo save
i his da>

Does that seem kike a complicated way to maintain an
appointment calendar tar the year'? Well, what is the
alternative? You will have to go to any stationery store
and buy a book which has preprinted calendar pages.

Why would anyone want to use a computerized calendar ;
Well, if the first thing you do each day is to turn on your
CoCo. it is not too hard to ran this program first. And
don't forget that if your CoCo is a business and office
machine, more than one person can use Han't Forget
each with his or her own calendai di*k. There is also the
convenience of setting up the second and succeeding years.
Don't Forget will cop) all the special occasion ileitis onio
your new disk for you.

Which system will serve yon best? There is an old
computer maxim that if a 3 x. 5 card will do the job, use
it; it is quicker and easier. Is this the case here? As one
who must live hy an appointment book. I am addicted
lo one that show* a week on facing pages with a column
lor caeh duy with hours and half-hours shown, plus room
lor memos, Each January when I gel a new one* I have
to go through and put in all ihe birthdays, anniversaries,
etc The phone rings all da> long, and I am constantly
checking, entering and altering entrics.

|s there anything the program cannot do as well as the
book" One ihmg I do frequently is check back and sec
when I mel with Mr. Jones. With Don't Forgei, after
loading, etc.. I can search the calendar hv kej word and
it will give me the calendar pages on which Mr. Jones*
name appears. My only other problem was that I could
not figure how lo show an appointment lor 10:30 or 3:15
- all Don't Forget 'i lines show even hours and I could
not overwrite them.

Compulerware is a large and dependable sollware vendor
and this program's quality is up to their standard. It
performs flawlessly and its HhRcft screen U siatc-oMhc-
nrt. As with most of their offerings, documentation is rather
ihm. with just enough instructions 10 get you going. Some
little problems we had to work out wilh some trial and

The author contends that people — especially children — are Hkefy to stay with a
program longer if joysticks are used for input. Test his theory on this joystick menu
and see if you agree.

Joystick-to-itiveness

This tutorial shows you I he advan-
tages of incorporating joysticks
in all your programs 1 have also
provided a program to give you a taste
of the joystick menu.

Here arc seven advantages:
I) Pcopk rind inputting with joy-
sticks easier because all the options
arc in from of the person. There's
no way a person will gel a syntas
error.

21 Inputting a number is let* error
prone. iVople don't have to keep
reaching up on the key hoard when
typing.

ij It's easier for kids and adults.
Most kids don't like Icarnine the
different commands keyboard
input programs hn\e. And adults
don't have two hours to spend
studying what the game will do
if you press a certain key,

4) Joysticks will make your program
more entertaining, enjoyable and
user-friendly. This will help people
improve what they 're doing instead
of being bogged down by the
tiring process ot keyboard input

i fT+C, Tenth fs tttt auittur vf the game
Do or Die, and h a member of Color
America V*ers Group J

5} It's easier lor people who can't
type. And, since the avcrauc kid
can't type, more kids will buy
joystick controlled games. When
you .add up .ill I he udulls and ki(^

that van I y«w joystick com rolled
program, you will have a hip
market for your program,
n) If you have played a multiple-
piaycr game, ynu know how hard
it is to keep maneuvering when
k\ your turn at the keyboard.
With joysticks, people can play
multiple- player program* lusiei
Kvcn sharing a joystick would be
more practical than using the
keyboard
7i Jo wicks sire just plain Inn.
If yotiVe convinced joysticks will
make your game a "cut above the rest,"
l lien type in the program below nr buy

The program listing below is a
joystick controlled menu that can be
used to choose parameters for Adven-
ture c^urnes. If you use a joystick menu
an your Advent ore, it would come after
all the data has been read and after the
title screen. You can do what you warn,

Jf you don't know how (a use the

How To Read Rainbow

Please nolo (hat all Ihe basic program
listings you will find in the rainbow are
formatted for a 32-character screen —so
thf.-y will show up just as I hay do on your
CoCa screen, One oasy way to check on
ihe accuracy of your typing is to com>
pate what character "goes under what
It the Characters match - and your tine
endings come out the same — you have
a prelly good way ol knowing that your
typing is accurate

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

Finally the little cassette symbol on
listings indicates that program rs availa-
ble through Ot*r RAINBOW DM TAPE SSTVrCe

An order "form tor this service is on ihe
in&erl card bound m the magazine.

Whal s A CoCo

CoCo is an alfeclion^tc name which
was first given ro the TRS-80 Color
Computer by us many tans, users and
owners As such, it is almost a generic
term for three computers, all of which
are very much alike.

When we use Ihe term CoCo we refer
totheTRS-BO Color Computer the TDP
System- 1 0X) Computer and the Dragon-
32 Computer It is easier than using the
three "given names throughout the

Jn most cases, when a specific com-
puter is mentioned, the application is for
that specif ic computer However
the TDP System-iOO and TRS-BQ Color
are, tor an purposes the same computer
in a different case, these terms are
almost always interchangeable

The Rainbow Check Plus

The small boxes thai you see accom-
panying programs in the the rainbow are
the Check system, which is designed
to h€tp you type m piograms accurately,

Rainbow Check PLUS will count the
number end values of characters you
lype m You can ihen compait Ihe
numbei you get to those primed jfl the
rainbow On longer piogrums, some
benchmark lines Eire given. When you

tf ach the end al one of those lines with
your lypmg, simply chuck to see it the
numbers match

To use the Rmnbow Chuck PLUS,
type in the program and i.hfWf. il for laler
use. then type m ihe command klj* and
press enter Once the program has run,
typeNiwENtEnto remove il from the area
where the program you're typing in will
go.

Now. whenever you press the down
arrow Key. your CoCo will give you the
checksum basec on me length and con-
tent ol Ihe program in memory This is to
check against the numbers printed m
the rainbow II your number 15 diffetem.
check Ihe listing carefully to be sure that
you typed tn the correct basic program
code. For more details on ihis helpful
utility refer to H. Allen Curtis article on
Page 21 of the February 19B4 rmk&ow

Since flamcow Check PLUS counts
spaces and punctuation, be sure to type
in the fisting exactly the way it s given m

Using Machine Language

Machine Language programs are one
of the features of the rainbow. There are
a number ol ways to get these pro-
grams into memory so that you can
operate them,

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

An editor-assembler attows you to
enter mnemonics into your CoCo and
then have the editor- assemble i assem-
ble them into spc-cihc instructions that
are understood by the 6B09 chip that
controls your computer

When you use an editor-assembler aii
you have to do. essentially, is copy the
relevam instructions (rom therai^b .
listing into CoCo.

Another method q1 getting an asstm-
hly language lifting into CoCo is called
hand assembly. As ihe name implies,
you do the assembly by hand. This can
somefrmes cause problems when you
have to set up an ORIGIN statement or
an EQUATE.. In short, you have to know
something about assembly to hand
assemble some programs

Use the following program i» you wish
to hand assemble machine language
listings

Addition

With the fun part over, it's time to get hack to arithmetic.
As you know, your editor assembler has several math-
oriented operation codes. And, despite my reluctance lo
admit it, additions and subtractions arc the foundation
ol assembly language programming,

Hither an K* or lb-hit operation is fSSfW addition that
adds the contents of a register to a specified number or
memory location, f he operation can use eit her accumulator
*A" or *B\ in H-bit functions, or both "A" and 'B* (register
*D1* in I6-bil functions. The following example Jem oust rates

J chose mcmorv location S4t>0 and 5402 10 store the
value* of 50 and 1 50 so you can sec whai i* gomg <iii
He\ 4iK» ls the beginning of I he lexi screen, and anything
stored there appears at I lit tup Icii-hund corner of your
video screen. Memory location S402 is I wo column?! to
the right on ihc lop row of your screen, OJ course, the
program moves too fast to *cc anything but the result,
which is the storage of 5(1 and t50 at Ihc top of the screen.
The value of 50 is represented by a reverse number 2 and
(51) is represented by a graphic symbol

Use the AO (absolute origin) switch to assemble the
program to memory. Then, to lest the program, type %'
to enter *bug. Press a EAK >o the screen won "1 scroll, then
type GSthhi 10 run the program, You can verify the displav
screen results by isping *R* to examine the registers.
Remember the register values arc in Hex.

Thr direct Approach

A* well as using the ADD op code in extended addressing,
you can also ose it in direct addressing, such as this program:

addition* in the *D* register can he either extended or direct.
In ihe above operation, the Hex number ,132B is loaded
in *D\ then *fV is stored in memory location $4<». This
puis m location 400 and S2B in locaiion 401. Then
S34.1D is loaded in + IV and *D* Ls stored in 5402 I his
puis S V| m 402 and S3D m $403,

I he Dumber stored ai 5400 and S401 is then added to
the number in D* and the result is stored at 5404, Again
ser l l ti memory is used for storage so yoo can sec the result*,

A Kit iirSirblmciinfi

I am pleased lo announce that subtraction works exacth
like addition, except! The "cxcepT is a fairly major one,
however, and introduces an important concept in computer
number handling.

But. before we gel into the complicated, Jei\ look at
some of ihe things that arc easy The following program
accomplishes a simple siibi Taction, using a memory location
and the W accumulator.

This program first loads aceumuJator H A" with ihe value

To calculate a negative value using two's complement,
first subtract the numbers using normal methods, then

When you reserve ibe MSB of a binary number a* a
*ign hit you have actually reduced Ihe value that numhej
is cupahlc Of %Uirin^ by hull To see this, look at the 8-
hit binary number IIIIMN. This number in decimal is
255, 1 28+64+32+ 16+8+4+2+ L When you reserve the first
bit as sign hit you have the binar> number II Mill, pr
127 in decimal.

In fuel, some computer* rcprrseni numbers in this way.
On the Radio Shad Model %, numbers above .12.768 are
represented as negative numbers. The highest mcrnorv
location is -I, nil her Ihnn f«55?fv there isn*t room lo show
ynu how such u number is formatted but, using a maximum
•■ aluc nf 19 rather than 65536, the following churl shows
how you can COUTH to l*> wiih such a method:

0 I 2 J A 5 6 7 II 9 -10 -4 -fl -7 -b -5 -4 -1 -2 -1

With this method, -4 now represents 11, -5 represent:, 15.
and - J represents Ifc

To show vmi how two's l< implement can accomplish
the job of subtracting, let's Mibuacl the binary number
ID from 5, In decimal, it looks like ibis.

hi MlW binaiy. when I he two numbers are subtracted, ihe
xesuh is

J flictaal, wlih a «l

en bit at

So far. aside from the number hemp negative, things
don't look too good. Bui, let's do a twos complement
ope ration on the result to complete the operation

Thai looks better and. even more impressive, il tj correct.
For simplicity in this example, only 4-bit numbers were
used The process is exactly the same fat target. H-hit or
16-bit numbers, howcvci

By now you probably wonder how your fttiUM knows
whether you are operating in lwo\ complement mode or
in absolute numbers. Ihe answer to the question ts thai
it doesn't, bui you do (at least you should), ,lus1 lo be
on the safe side, the 684)9 always acts as though two's
complement is being used and oulput.s ihe necessary
information. If you don'i need iwos complement, you can
ignore the signs that ihe processor send* oui. If you need
two's complement, you can make use of the signs.

Well, now JfOU need |o know that the flags for regain*

best way to tec this b to execute the program again, hut
this time single step through It

To single step, first assemble the program in memory
without errors Then go to zeu£ and type STfifiT. The

beginning at SWT. Enter a comma every time you wish
to im pie men i a new >tep.

After each step you can look al the registers by entering
TC I xamine the registers after lines titillO and 00140

Building A Program
A Piece At A Time

Bv Dimirl \dums iMisthiini
Hainbmv t oiUr i !iu Li ri^ Lililor

Tim month we arc going la talk
about a feature in OKI i Pascal
which provides yoo with the
ability to develop and compile an
■ nJiMiUhM program >m sacral '•niiillei
pieces ratherihan us o single, large unit
While Ihln separate wupiUttitm feature
is not part of standard PASt AU must
Pascal compilers (including pascauw,
UGSD PASCAL .mil Microsoft PASCAL
|nr the IBM PC) incorporate a form
of it.

There are a nombcr of advantages
m developing a pjueiaTii ml his mamiei

I) You can develop a set ol utility
routines as a program "piece," and then
incorporate I hut piece into many
diflcreni programs.

2> You can t:ikc u targe program \*nh
perhaps man> subsystems and make
each son-system a program "piece.**
This allows you 10 develop and lest each

sub-system individually before trying to
put I lie whole thing together.

.1) You can let more than one person
work nu an individual program at the
same- tune h\ Inning raeh one develop
Jus own "piece"* at I be program.

4) You can use more than one
programming language in a single
program by having each "piece" written
in a Jiltercni language With iriir />/ FT
Postal Workbench, trie languages
available are PascaI and
assembler,

Modules

J he term module is used to describe
one of ihesc program pieces regardless
or which programming language is used

10 develop it. A I I he same liniir, PF'FT
Paieal has a keyword, MODULE,
which denotes a particular lype of

1 1 A Mr At module In Of: FT 'Pascal there
ore two type* of modules:

1) A PROGRAM is a module that
contain* subroutines, variables
and the main sequence of instruc-
tions to be executed by the overall
program

2) A MODULE is a [nodule that
contain* subroutines and
variables,

A complete program can be made up
of one or more modules bui one of

these {and no more than one) must be
a PROGRAM module. As you can see,
every program we have written so far
has been developed as a single PRO-
GRAM module.

We already know what the syntax of
a PROGRAM module is The syntax
of ,i MOfU'l I i- almovl the same:

• i-.'. IOI k*f I -vf ..I ! ■-

<typc declaration^

<V*Tl(lhlr •!'•< li:>! UwV*5

<fTor.i-4i.rcr tad functtfio dcCler*UlrtwJ

The onlv differences between a
MODULE and PROGRAM nrc that
the MODULE does not have any
parameters, nor does it have the BEGIN
<exccuiable statcments>at the botiom
lite a PROGRAM does.

PUBLIC and EXTERNAL

The purpose of a MODULE is to
provide variables, procedures and
fufictioos for use by the PROGRAM

URITE FOR
UR CRTRLOGj

In this example, we hqvc a number
of private and /?nM< iambic*, proce-
dures Hnd fu net i tins, The variables *R\
T and "C" are nil private variable* in
that I hey yre known only within the
module Keyboardists. The variable
This Dale, on the other hand, is a pub ltd
vuniihk- because ihe V \ Ft ->t.jlcmenl
*hieh declares it has a PUBLIC
attribute fallowing il. This mean* thai
This Dale can be accessed by other
modules while *R\T and 'C cannot.

By 1 he soi me loken, ihe procedure
DisplayKrror is a private prtieedurc
while I he fund ions Ciel Percent ant!
EelYesNo. its well us the procedure
ficiDiiie. are Ml publicly known These
lasi three all have the PUBLIC attribute
fnlliiwifigihe FUNCTION or PROCF-
I) I RE ^tiuemem

Kcavpns Tcir I tunning Pl'BLEf

The above declaration* have been
made lor ;i pariiedur purpose. In this
ease, the variables *R\ T and T" are
local work variable* Tor use by all the
routines in Key board Data. There no
rea.son lo allow other modules to ulll-v.

these variables and> by keeping them
private, we can ensure that other
modules do not inadvertently modify
them,

ThbDatc, oniric other hand, is piihiic
because it contains the result of the
procedure Get Dale, Routines in other
modules would invoke Gel Date in
order lo prompt for and validate a dale.
On return, ihe resulting date can he
accessed from Thi s Dale

The routines Gel Percent. GclYesNo
and Gel Date are all publicly known
because they represent the purpose of
the module to prompt for and validate
■. :i ri:-j - n pehol lixita I n>in the keyh iard
Therefore , these umiii^ will he directly
invoked from uther modules in order
to perform a particular function. J he
procedure DisplayErroi has riul been
publicly declared because it is merely
a locai utility routine Tor u*c cxcIuHivcly
within the module.

The EXTERNAL Part

The next ihimj lo do i« access this
module from your main program
example:

In this program, we had to declare
the type Date in order to property
declare the external variable IhisDate,
Like the PUBLIC attribute, cxtuiul
variables arc declared in a V A R
statement that contains the keyword
EXTLRNAL immediately after the
keyword VAR.

The routines Get Percent. GetYesNo
and tit t D ate are declared £ X T F R N A I
Notice that alter the declarations of
These routines, there is only the word
EXTERNAL; there is no body to these
routines.

Down in the executable portion of
the program, the external variable and
routines are used exactly as though they
were local to this module.

Linking Ihe Modules Together

All of ihcHc external identifiers
represent Ihingj* which arc not present
■ ti ihe program module My Program*
hut which arc present in other modules
which will be linked together with
Wi Pr. >t>rutn hy D/iTT Linker. Because
I hey arc not locally present, ihe compiler
cannot completely generate the required
instructions when any of them arc
referenced by executable statement*.

Whui the compiler does is generate
it nnie to i he linker thai thir, module
is referencing an item that is present
in some other module. Later, when the
linker reads in all the modules that arc
lo be linked together, il can deienmiic
whin PUBLIC identifiers are present
and wha( their addresses arc. Then,
when Ihe linker encounters one ol these
note* from (he compiler, it can deter mine
what the proper address should he and
inserts il ai that point in the code tn
complete the instruction.

IMKH^ACE Blocks

As vou can see, (here arc a number
of lines of code the main program must
have in order to allow it to access the
module Keyboard Data, These lines
essentially declare the public interface
to the module Key board Data. DEFT
Pascal contains a second mechanism
called an INTERFAX 1 Mock lor
specifying the inlcrface to a module,
Htr nample, using ihe INTER* A< I
block in \t yVrnjtrurn Would look like
this:

PROGRAM Hy Program (Input , Out put );

TYPE Date * RECORD

Honth, Day j Year : Integer;
END;

VAR EXTERNAL

This Date : Bate;

VAR ... (* local variables *)

FUNCTION GetPercent (Prompt : String) : Real;
EXTERNAL;

FUNCTION GctYcsNo (Prompt : String) : Boolean i
EXTERNAL ;

PROCEDURE GetDate (Prompt : String);
EXTERNAL;

. (* local procedures and functions *)
BEGIN

IF GetPercent ( 1 STARTING PERCENT' ) > ,5 THEN BEGIN
« GetDatc C * STARTING DATE* ) ;
IF ThlsDatc.Year > 1060 THEN

END.

252 THE RAINBOW Mirth

INTERFACE Key board Da ta ;

TYPE Date - RECORD

Month, Day, Year : Integer;
END;

VAR ThlsDate I Date;

FUNCTION GetPerccnt (Prompt i String) : Realj
FUNCTION GetYeaNo (Prompt : String) : Boolean;
PROCEDURE Get Date (Prompt I String) j

EM);

PROGRAM HyFrograa C Inputs Output);

VAR ... (* local variables *>

•** C* local procedures and functions *)

BEGIN

IF GetPercent ( 1 STARTING PERCENT 1 ) > *5 THEN BEGIN
Get&ate ( * STARTING DATE');
IF ThisDate.Year > I960 THEN ***

END.

I'sirig (his method, there is no
declaration of any ol public identifiers
(or the required TV IT definition) from
ihe module KcyboardData in the
program My Program. Instead, the
enure interface appears to be prf tiffined*
Notice in ttK WTEKFACF hlocfc thai
there is no uw of the keyword EXTER-
NA I,, nor do any til Ihe proved urus oi
functions have bodies Thai u, because
all ihc variable*, procedures and
functions declared with an ifilerfsice

Mock are automatically declared as
c \tern id

An INTERFACE block m usually
put in n sen ;i rale source fijc from any
other source Hie that might need it. A
%C compiler directive is then used to
ine I ude t he dec liif at i oni at the he p i n ro n ii
of the file. The suridurd PASCAL library
is declared in exactly this way by always
doing an implicit %C on the lite
PASCALfBl £,Vf at the beginning of
jitiv l>\Sl \l program.

Example Program

This month's example program
pel u iilly consist* o[ two separate lEstings.
The first it an expanded version of our
KcyboardData module. It contains the
three public routines and variables that
ue have been using as ao example

The second is a listing of the program
/merest which com pule*, the total value
of an investment. You supply beginning
and ending dales, the interest rate,
whether il is compounded quarterly {as
opposed to yearly! and the initial
investment amount, tnttfrrst use* the
routines m Keyboard Data in order to
prompt for and validate the information
that fa entered. It alio contains a Local
subroutine* Co tint Days, that gives an
absolute day number to a given date.

You will notice that we used an
INTERFACE block to link tmtrtst to
Key hoard Data. The main program
then not only used the variable, function
and procedure identifiers, but also the
type Dale which was declared in the
interface,

You use EX4 MOD to examine a
disk file and determine what type of
modules it contains. It reports the
modules language, type, si/e. data
storage requirements, revision number,
edition and the offset from I he beginning
of the module 10 its execution address
Like the LOOKUP package above.
EXA MOD\ out put can he redirected
to any device ot file on your computer,

CtWRFV gives you a shorthand
met hud of changing the version number
of b AS ICO* I -code or 68(W object code
modules in a Tile 1 1 automatically
updates the header parity and CRC of
the module after it makes the change
for you

The LUMar package Jrom JHM is a
group of f>8>09 object code modules thai
can he called from KAStttw to perform
a number of tasks that are olten
required in business programs- Some

of these ta*ks can already he performed
from bash'W by running the SHELL
command. Oihers could be written
direct I v in flASicw. However, both of
these methods add overhead; either in
the lor ai ot additional jobs running
concurrently un your computer or in
extra mcmon and stoker speed.

II >ou plan in awe the routines a lot
you can even load them into memory
with a command in your STARTUP
file. They total less than 4K bytes nl
memory, I n save space, well define the
individual routines thai come with
IjdMat in table form

Routine function

Bhll Fill a string with spaces

Caps Capitalize all lowercase
letters in a string

CFdl Fill a string with the

Cmpar Compare corresponding
fields in similar structures

ComCRC Compute the cyclic re-
dundancy value of a
module

FilMjcr Return files' si/e or po-
sition in file

GAti Return the attributes of
a Ilk

I iet 1 D R ctu map rucess number

(J Mod Return names nl modules

GPri Report the priority nl a

HiC Convert OS -9 n rings in

BASICW strings

Psil Position a source string

SclULD Change a program's user

cess temporarily
SPri Set the priority of a

process

Siiucc/ Remove all spaces from
a string

Tctrl Set characteristic* of a
terminal

Tnmbr Report the name of a
User's terminal

The A DM 8 package gives you a way
to copy data structures, comments and
subroutines from a Library Pic lo a
source code file This makes it caster
lo use the tame routines over and over,
and eliminates the lime wasted when

you continue lo rccodc the same
routines each time you need them.

($AM U a package ui HASictw
programs that let you create and Use
Indexed Sequential files It eon lams
three prog i am* and one procedure to
let you create, update, review or
reorganize youi ukv

Another JHM package named XMF
will let you use ISAM I lies lhai require
more than one key Lor example, when
you are searching through a 11 le con-
taining a list of your employees, you
may want to locate an employee's
record by name, by payroll number or
even by the date he came to work for
you. The A7f F pack age helps you create
the muEu*kc\ index you need to do this
type of job.

And finally, J6M sells a siring
arithmetic system that lets you add,
subtract, multiply, divide or compare
very large a umbers accurately. When
we say large, we mean 18 digits. Ii is
well-suited for financial application*
where accuracy is a must.

In recent months JBM has released
three new packages We haven't seen
thenv but they look like they could
prove useful in a typical office. They
are .\f£SS \G I , u niuJu terminal mail
system for OS-£l evel II systems; t 4U
a personal appoint men I diary: and
GEN VS. a stand-alone sort program.

C ommrnls about Yertdon LOLUfl

The local Radii* Shack in S pi i ngl idd .
V ;J tinalh received their second
shipment of Color Computer OS-9
Version 1.01 00 a few days be I ore
Christmas, By the lime i received my
copy, the comments were starting To
arrive.

Hawkins oi I ad y smith. Wis,, reporting
that the new version of OS-9 would not
work with the Dusk Fa utility package
sold by Computcrware. Since at one
time or another I have used bulb
Co mputcrw arc's new VC DISK module
and D. P. Johnson s StMSK package,
1 was concerned.

Yet, stnee I knew both packages
simply contained replacement module*

module. I couldn't imagine why (hey
wouldn't work. But. rest easy (rtends.
Roth packages do work with the new
Radio Shack Version 1 .01.00. I tried
them myself, I lien, later I confirmed
thai other people were using both
packages with the new version i»1 OS-

spoke wjth Brian l,ant/, a free-lance

authored Com pu I er ware's new DA TA
8 A iVA database manager p roc rmn, He
reported ihat he also has been using
hnth SDfSh and Compulerwarc's
CCDMK with Version 1.01.00. This
make* me Ihink Ihat a reminder is
necessary.

Remember' When Von purchase ihe
new version of GS-o t you mast again

I suspect Hawkins honied up
with his new Version 1. 01. 00 disk, and
Then iricd lo read a double-* ided, 40-
truck dink he hud initialized after
installing Cnmputerwnre's CCDJSK
into Version 1.00 00. Since i be t t PtSh
moduk in the new version of OS-9 is
basically ihe same a* the CCDISK
modute in the old version, it mill cannot
read double-sided disk v Thus, Uuwksm
found a problem. Again! Aficr you
hring your new Version a\ OS-9 to life,
don 1 ! forget to reinstall any custom
module*. \mi have tH'fii tisme.

Along those lines, here's a trick you
can use with D- P. Johnson'* SDISK.
If you only own single-sided disk drives
and only use SDISK to read or write
a standard OS-9 di.sk every once in

After you have used SDISK and

DVMPM

Ad nanus wrote ihis program before
he realized the QS>9 DUMP uldily had
an **'V* option. You can use it in dump
a file to the printer or the screen.

When you start ft, DOMPM asks if
you want to dump 10 the printer or
screen. Next, it asks lor upaihlist Here,
you enter the pathlist to the dircclory
thai contains the file. It u ill give you
a directory of that pathlist and ask you
if you want another pathlist

If you have the right directory, you'll
be asked for the name of the lik you
would Si ke lo dump 11 you jsked for
the printer eariier. Pl'.hfPM will dump
out 16 addresses per line h dumps eight
addresses per line on your screen. Both
modes display the ASCII values of
character-, at the end of each line. When
the program is finished, it asks you if
you want to dump another file

DeLfilr wu\ just a "fool -a round'*

I In* program run* much like

then displays a directory It then asks
you hir the name of the file you would
like to delete, alter you type the name,
it delete* the file and asks if you want

I hese two programs were my first

write .1 piogrum wuli no line Humbert,
goto statements or GOSUB staicments.
Again, I wrote [>t Kf P\f because I
didn't know the "-I option was

Now you can recover that deleted file
By Brian A. Lantz

E

ver have something like this happen? Delete
the wrong Rlc, thinking you had a readable
backup that only produces an I/O Error?

In Extended Color BASIC this has happened
to mc many times, as it may have to you.
Fortunately, a long time ago 1 figured out
how to painfully recover the fitefs). If this
has happened to you more than once, you may have also.

But what about under OS-9? If you are like most OS-9 users
(not just CoCo users), you are totally lost when it comes

to recovering a deleted file* What's that? You say only a dummy
has that happen! Only a beginner!

I can disprove that by using an Incident that happened to a friend
of mine as an example. This friend is a computer professional from
way hack. Almost two decades ago he was involved in the
development ol one of the finest educational languages developed
to date. He helped design one of the largest computer installations
I have ever seen. Whai this man doesn't know about computers
doesn't need 10 be known! Surely something like this could not
happen lo a knowledgeable, computer professional like this, right?

He was in »hc process of cleaning up his hard disk when someone
distracted him. Instead of typing in the entire line, he typed:

DELD1R . v\ i"KR

Murphy's law took its turn again as he looked at the terminal to

Not knowing his previous mistake of
an incomplete palhlisu he r uf course,
typed in a 'D' aruj entered So, OS~ u
proceeded to delete all the files in his
current directory. This directory had
the only copies of the source Tor a new
version of a complete new language for
OS-9. Before the mistake was nolued,
over In file* were deleted! I promptly
received a desperate telephone call tit
help him out. The happy ending b that
we were able to restore 16 out nl 16
files, completely!

How rci Save Deleted File*

Now for the "how-to 1 ' pan. How can
ww save those valuable dies d they
happen to be deleted bv mistake or
accident?

First, the ideal tool needed; the
PATCH utility command. This is
&vai table in Ihe frisk tfa & Vtiiilm
package from Compute n» art Other
utilities can produce the same results,
but 1 recommend using PATCH for the

least work and fastest recovery lime.
I will explain haw to restore files using
PA1CH, but even if you don't have
PATCH t the principles are the same.

Now for a little knowledge of how
things are organized on (be OS-9 disk
doesn't refer to a disk bv track
number and sector number like most
operating systems (i.e.. Ff FX). GS-9
uses a Logical Sector Number MSN)
The first sector of the disk is LSN 0,
followed by LSN I, etc Fhis IS the way
OS-9 can access differ ent types of drives
in l he -.a me way No matter how many
tracks and vector* it has, LSN 43 is the
44t h actual sector u\ ilie di*k,

266 THE RAINBOW MUCH nu&

"A File Descriptor is
a one-sector
information center for
the fiio; each fite has
one, including
directories. Severs!
things are stored in the
Fife Descriptor sector,
including the fife's
attributes, the file
owner's user number,
the modification date
and creation date, the
fife size and the
segment list."

The OS*9 directory is a Utile different
from Color Disk Basic, also. Each
directory entry is 32 bytes long- J be
first 29 bytes arc the filename. 1 be last
character of the filename ha* the Most
Significant Bit set. The other three bytes
are the pointer to the File Descriptor
sector of the file.

A File Descriptor is ll one-sector
information center for the 5k; each file
has one. including directories. Several
things ure siored in the File Descriptor
sector, including the file's at I rib met
{viewed with a OJR L), the file owner's
usei numhei. the Mu'dif»catiusi dale and
creation date, the lite sue and the

segment list. The segment list is a table
of five -byte entries Mint tell where the
fife's sectors are actually located, and
how many sectors arc in each segment.

I nd of Basic Training

Now Wilh (lie basics oul ol the wa> .
I..' i '> I li rough the restoration process.
Die first thing that needs to he done
is n> enter the PATCH ulility. Ict%
assume lor our discussion that the
deleted file was named NEEDED. FfLE.
and was located on drive , DO. We
would enter the PATCH utility by
typing:

PATCH -OOP

This opens the em ire disk located in
drive DO for patching. The next thing
*e sec I hi: iop>f inhi run ice. and the
prompt T which look* Like this:

The first I hing we want to do is locale
the root directory for / DO. Ffifii
ail .pi itiatmn ii local t-d m I KN 0, along
with several oi her useful I id bits. To do
this we use the D" opium of PATCH,
This will display in Hex and decimal
l he byies requested, If only one number
is given on the command line, then 256
bytes are displayed, starling with ihe
byte requested To display LSN 0 t type:

The result is Tsample I, This Is frnm
one oi my disks, and is actual output
from PATCH. The root directory's File
Deveripior sector is located in the
eighth, ninth and tenth bytes of I SN
U\ which, in this case, is 00 00 03. You
will find that, wilh rare exceptions, the
root directory's bile Descriptor sector
will alway s be this, but it is wise to check
anyway.

In order to find a file, we mu.M loaf

Note this i we needed two additional

been given as:
