Thanks for all of the replies.

This type of thing always strikes me as being "programming archeology", in
that you had to be there to really know why something was done (what it is
doing is not too hard to discern, but the "why's" become dimmer over

time).

There should probably be some project launched as a wiki to collect and
document these kinds of idioms. Somebody 10 years from now won't have any
idea why this was done, and those who remember, well, they might not be on
this list. Legacy COBOL is probably the same way (to pick another widely
used language with an enormous legacy code base).

Absolutely.  MULT 100.0001 has to go in there!  I can't imagine anybody
but an (old) RPG programmer being able to decipher that one.

I have a couple of old 8085 assembler tricks rattling around in my head
as well <grin>.
