QBasic variables and call absoluteby Ben (no login)
I was wondering about how to access QBasic variables with assembly then calling absolute. I know the obvious way of passing VARPTR and VARSEG to stack
;above won't actually work, just example.
But I know that it's possible to store stuff with NASM like this:
stuff: dw 0
So what I need to know is this: does NASM view the above as one of them "macros" (not sure about that stuff) and store the "stuff" in memory and
...nasm generated stuff...
Or maybe it stores the stuff in the ram close or something or same segment where the mov [stuff],50 is possible cpu instruction.
So what I want to know is this: can variables in qbasic can be put somewhere where it takes one mov to put stuff in/out of them?
