split a basic program into two different areas of RAM?
|
| |
...
I think you could simply let the next-line pointer of the last program
line in the "lower" part point to $4000, and treat the program as if it
was one single thing. I.e. just GOTO and GOSUB to your heart's content
between the two parts. You might or might not be able to just let it run
past the "break", you'd have to try, I'm not sure if the line linking... more »

I want to know, if it's possible, how to change the state of a pixel in hires screen with a poke instruction.

Mixed Language programming
|
| |
Hi everyone,
Last year I started to learn the basics of i386/x86-64 assembly
language using NASM armed with an online book written by Dr Paul
Carter. It goes without saying a beginner needs to see an output of
the result(s) of their programs. It is not a trivial thing for
beginners to write their I/O routines. Since the day of the original... more »

"LINKER", a program found on Asimov's "EDASM.DSK"
|
| |
Hi, y'all!
First of all, if you're going to play with "LINKER", do NOT just
launch it. First, launch "EDASM.SYSTEM". Then, enter 'EXIT LINKER'.
If you start "LINKER" without going through "EDASM.SYSTEM", any error
messages issued by "LINKER" will disappear before you get to read
them. I wasted LOTS of time before I finally figured that one out.... more »

ProDOS Assembly Tools docs
|
| |
I know I'll probably get crucified for this, but....
Looking for official documentation for ProDOS EDASM. I know it was posted to the gmail account and promptly taken down over copyright issues. However, since it was never determined who holds the copyright (besides Apple) and it isn't for sale on any of the Apple II sites, I was going to ask if someone who has a scan of the docs to send it to me with the caveat that I'd purchase it whenever it became available (or sell me their hard copy). I have the DOS Toolkit Assembler manual, but there were enough changes between the DOS and ProDOS version to warrant the need for accessing the newer docs.... more »
