[A86] Re: Hey All, Some beginner Question :)


Ok, I know that is not a beginner question but this is an interesting question,
So .. I need to use the home screen hook so this will be [sqrt]Home..
It is called when the input buffer is modified(If it work like in the 83+ .. this will be simple to port my rpn parser ) ... But I can't make it work because TASM dos'nt like 2 .org in one file.. can somone help me with that detail, I can't make homestck( an prog that use home screen hook ) compile right.. I don't use asm studio because I'm in linux.. So How to compile a prog with 2 .org to make it work Correctly .. ??

Thx all
