Commodore 128 & Commodore 64
TIPS AND HINTS
Various sources used.
Complete reference listing is available upon request.
128 Key Repeat
The keys on the C-128
repeat when held down. If you want to change the C-128 to have non-repeating
keys like the C-64, type POKE 2594,0. This will only allow only the
spacebar, the INST/DEL key, and the cursor keys to repeat. To return to
normal, type POKE 2594,128 try It.
Load and Run Programs
If you type a colon ":"
after the ",8. you can hold down the shift key and press RUN/STOP and the
program will automatically load and run.
Did You Know?
With SPEEDSCRIPT and
PAPERCLIP (and maybe other word processors) you can draw lines on the screen
by holdln9 down the Commodore key and the @ key.
I Spy and Secret Codes
Partly out of pride and
partly as a form of security and copy protection programmers and system
designers will often sign" their work by embedding strange pieces of code or
cute messages In their programs. The most famous "signature" In Commodore
circles Is the music code which plays "POMP and CIRCUMSTANCE" stuck In the
middle of BABY SCRIPT. The latest 1s In the C-128 and you can see it for
yourself. Type in SYS32800,123,45,6 (In C-128 mode of course).
Fool Your Friends!
Try this on your friends
when they aren't looking. Type POKE 744,0 on their C-64 and then ask to look
at their latest BASIC program creation to see the listing. All they will be
able to show you are the line numbers. Or try POKE 22,35 and list the
program with no line numbers. Now it is up to you to get your friends
computer functional again, no fair turning it off and on ...that's the coward's way
Cold Start vs. Warm Start?
The C-64 User's Guide
says Cold Start (SYS 64738) restarts the machine as if It were Just powered
up. The fact is, It just resets all pointers in Zero Page. Your variables
are still there, but the machine does not recognize their presence. Warm
start (SYS 64759), does the same thing with the exception of screen display.
The System call I use to cold start the 64 is SYS 64760. After using this
call, I can 90 into the memory and all traces of my old arrays and variables
have been erased.
