I am using tasm 5.0, and I noticed an annoying occurence. Immediate values are assumed to be words. So when I write an immediate value to memory that is a byte value, it writes over the next byte in memory with a zero! Took me a while to figure out what the heck was going wrong with the code...

Well, I figured it out. I had to cast the function into a int (PASCAL far*)() like this: ptr=(int(PASCAL far*)())myproc; Just figured I'd let you know how it is done.

I have a simple windows program that "should" have a standard window with a nice menu. I should be able to click on Help->about and see a nice little box. In order for this to work perfectly (a quick fix adds a small bug in which the about box doesn't dissapear after you click OK) I...

What do the functions brk and sbrk do in C? I need to allocate more core memory, and I need some good information on how these functions work. Thanks.
