I believe the following sequence of Assembly Language code is Intel x86 based but I am not sure.
JMPC
SET_W
SET_SW
SET_W
What do SET_W and SET_SW do?
It's been a few years since I've done any Assembly (college, Motorola 68k too) but it looks like SET_W can be an alias for SETW which is a looping mode subroutine to write the word value (the 'W' part of SET_W) to all components of a block. SET_SW may be for short word or byte? I'm taking a stab at the last part there. Here's the link I found: RTF/68k Syntax
