Did the use of your self-modifying code in the past propelled you to the
future from where you're sending us mail in the present? :-)

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.
Back when I took Assembly langauge (8086) at college, I used
self-modifying code in one of the assignments (the teacher and I didn't get
along and this was my attempt at getting a "rise" out of the teacher). The
assignment was to sort a list of numbers in ascending or descending order
(depending upon user input) so I simply changed the jump instruction after
the compare in the sort routine. It saved either two copies of the routine
(differing in only a single instruction), a complicated logical nest in the
middle of a sort routine, or using a callback routine.
As far as I can recall, that was the *only* time I've ever done
self-modifying code.
