I have yet to see a good use for self-modifying code.
Other than
subroutines and interupts placing data into a code segement the only
self modifying code I have seen was for the 8088.
Self-modifying code was somewhat common in the 6502 world. I have seen
(and written) several examples for the PET, VIC-20, C-64, and Apple II.
It's of limited use in cached architectures like the 68030, but it would
work fine with, say, the 68000, 68008, or 68010; but by that time, self-
modifying code was "out of fashion" (plus the 680x0 instruction set is
so much richer than the 6502 that there's much less need to try it).
