Back in 1981, one of the first bugs I had to find/fix was a COBOL (VS?) routine
intended to distribute the rounding difference to a set of records. Perform
until zero left to distribute. It looped at negative zero. I didn't write it, I
don't remember my precise fix.

Doing integer--as opposed to real fixed-point--arithmetic with
packed-decimal values is the real culprit here.
Integer arithmetic should never be done with anything but binary
integers. Operations on them are register operations, which are much
faster than storage-to-storage ones; and zero is

No such thing. A field is either comp-3 (or, nowadays, packed-decimal)
or comp (nowadays, binary) - or floating point which few COBOL
programs use.

If you are using AFP, you can create BCOCA (Bar Code Object Content

See how to use the AFP Toolbox from COBOL applications to create bar

With packed decimal data, the probability that the use of an

Rather, I would argue that mainframe developers generally have a
