Hi,

just curious, to your knowledge, what is the reason behind forcing
programmer to adjust stack manually after each OS call? I mean favorite:

move.w #param,-(sp)
trap #xy
addq.l #2,sp

why last line couldn't be done in OS?

I guess because the OS does not know how many params you actually havepushed.
