The genius who wrote it declared all subscripts as COMP-3. Changing
them to COMP-4 knocked 30% off the execution time.

Oh, wait, COBOL didn’t have typedefs ...
I suppose I could have done the equivalent of s/COMP-3/COMP-4/ in the
text editor of the day, but that would have also changed the fields that
were not only legitimately COMP-3, but which could not have been held in
a COMP-4 variable.
Sometimes you just gotta Do the Right Thing, no matter how long it

Helps if you are charging by the hour. ;)
