Shane,
I had a few occurrences of looking at code that way. After looking at
a IFCEREP1 module I found a really bad code sequence (causing cpu
usage to sky rocket when running a specific report) The damn module
did a sequential table look up that was absolutely terrible. It
could have been handled with very few instructions with a load and a
shift left double. For each device it looped through a table.
Something a rookie would have done. I tried to apar it and they
refused to take it as a performance issue. Fast forward 20+ years and
the damn module still sucks up cpu time. No one cares.

Too long ago ....
I do however recall sitting down at a (very old) fiche reader in
the computer room at one time looking through the source for
IEBCOPY. Hard way to read code.
Can't remember if we had an actual problem, of it was just a "I
wonder" moment.
