True. I hadn't considered compatibility with the overflow behavior of the
fixed format operations. That doesn't change my NSHO though. I maintain
that if you insist on using techniques that require that behavior, you
should be forced to use the fixed columnar format, and key your programs on
punched cards too. No sense using up valuable terminal time when you're
just coding.
