Then don't you use macros in functions?


Actually no. Or rather, I haven't used functions at all so far, just macros.


Writing up how it works for a few real world test cases helps a great deal in understanding if it really works or where the pitfalls are.


Yes, I do TDD. I'll have to look ...

Yes.
For a function, you would need to allocate the address permanently. It works better with macros.

The idea is to be able to use the zero page for all variables. You allocate a zp address when you need it, and when you are done with it (ie. at the end of the macro/function scope), you deallocate it.

It would be cleaner to have it take the exit condition back to the original != 0 check, but I'm not sure how to actually make that work. It's unlikely that I'm ever going to get *perfect* code out of LLVM, only better or worse.

Well, you can't expect a C compiler to output asm as a human would ...

So, if file A depends on File B and C, and File B and C both depend on file D, What file should include what?

If they contain only macros, I guess they can use include guards and each file can include it's dependencies AT THE TOP, before the code using them.

But if they contain instructions or ...

Hi!

I want to organize my code in multiple files, and have them depend on each other.

Acme has a pseudo opcode for including source: "!src" But when including, you must be careful to JMP past the included instructions/data or include them *after* the main function entry point. But when including ...

Hi!

I am trying to learn ASM on the c64, using ACME.

I'm a software developer by trade, but I do pretty much only web dev. Full stack typescript, react, graphql, postgres and all that good stuff.

Recently I wanted to get back to my roots. I grew up with a c64 in the early 90s, playing pirated ...
