A program also needs style if it is
going to impress anyone and the 128
Font Editor and the Message Con-
struction Kit for the C64 provide easy
routes to adding a 'designer look' to
your routines.
Instead of attaching a printer or
disk drive to the serial port, using it to
link through to another C64, C128,
Plus 4 or C16 can add a new dimen-
sion to games playing. With the Bus
Route 64 program you possess a key
which opens up the world of interac-
tive, two player games.
On the technical side there are
memory maps of the C128, C64 and
1541 disk drive Arith detailed tables of
many more vital statistics in a quick
reference format.
W
t
information to help any ser-
ious C64 or Cl28 user to get the best
from their computer. Utilities for
programmers and other computer us-
ers are backed-up by an informative
technical section and an extensive
hints and tips guide.
If your forte is Basic program-
ming, the GTX Compiler can convert
a program to run at over 30 times its
normal speed.
The Your Commodore Serious Users
Guide is more than a magazine, it's a
reference guide that deserves a place
beside every Commodore 64 or 128.

Ignore the square brackets and just
type in a shifted upward pointing
arrow (ie. the pi symbol).
down the CTRL key as you press N,
press the cursor key down twice, the
cursor left key five times, press the key
marked BLUE while holding down the
CTRL key, press the F3 key and,
finally hold the Commodore key down
while pressing the number two key (C2
would of course make the computer
print in brown).
Always remember that you should
only have a row of graphics characters
on your screen with no square brackets
and no commas, unless something like
this appears:
[SS],[C*]
In this case the two characters should
have a comma between them.
On rare occasions [REV Ti will
appear in a listing. This is a delete
symbol and is created by entering the
line up to this mnemonic. Then type a
closing quotation mark (SHIFT & 2)
and delete it. This gets the computer
out of quotes mode. Hold down CTRL
and press the number nine key
(RVSON), type the relevant number of
reversed T's and then hold down
CTRL and press zero (RN/SOFT).
Next type another quotation mark and
delete it again. Now finish the line and
press RETURN.
A list of these special cases is given
in the table but remember that only
one of these mnemonics will appear
outside of a PRINT string: the symbol
for pi. This may appear when its value
is needed in a calculation so this may
look something like:

around the keyboard for a suitable
graphic symbol. You may also have
noticed the funny numbers by the side
of each line of the listing. Fret no more,
it's all part of our easy entry aid.
Instead of those nasty graphics and
rows of countless spaces in PRINT
statements and strings we use a special
coding system. The code, or
mnemonic, is always contained in
square brackets and you'll soon learn
to decipher their meanings.
For example, [SA] would mean
type in a Shifted A, or an ace of spades
in layman's terms, and [SA10] would
mean a row of ten of these symbols.
[S+2] means hold down the shift
key and press the plus key twice. It
doesn't take a great leap of logic to
realise that [C+2] means exactly the
same thing except that the Commo-
dore key (bottom left of the keyboard)
is held down instead of the shift key.
If more than two spaces appear in a
statement then this will be printed as
[SPCA] or, exceptionally, [SSPC4].
Translated into English this means
press the spacebar four times or in the
latter case hold the shift key down
while you do it.
A string of special characters could
appear as:
[CTRL N, DOWN2,LEFT5,BLUE,
F3,C3]
This would be achieved by holding

Checksum Program
immediately because it will be used
with most of the present and future
listings appearing in Your
Commodore.
At the start of each programming
session, load Checksum and run it.
The screen will turn brown with yellow
characters and each time you type in a
line and press the RETURN key a
number will appear on the screen in
white. This should be the same as the
corresponding value in the magazine.
If the two values don't relate to one'
another, you have not copied the line
exactly as printed so go back and check
each character carefully. When you
find the error simply correct it and
press RETURN again.
If you want to turn off the checker
simply type SYS49I52 and the screen
will return to the familiar blue colours.
You can then do whatever it was you
wanted to do and if this doesn't use the
area where Checksum lies you can go
back to it with the same SYS
command.
No system is foolproof but the
chances of two errors cancelling one
another out are so remote that we
believe our listings are more reliable
than any other magazine in the world.
So get typingl
The hexadecimal numbers appearing
in a column to the left of the listing
should not be typed in with the
program. These are merely checksum
values and are there to help you get
each line right. Don't worry if you
don't understand the hexadecimal
system, as long as you can compare
two characters on the screen with the
corresponding two characters in the
magazine you can use our line
checking program.
Type in the Checksum Program,
make sure that you've not made any
mistakes and save it to tape or disk
