IBM has used this sort of call return fairly consistently in many of their
development products. In fact, some of the red books on PL/1 programming
(smile) recommended using function calls instead of procedure calls and
returning integer values exactly as you prescribe above.
My first C programs were highly influenced by my mental separation
of procedures and functions. Those of you who have drunken heavily of
Pascal can probably relate to this odd state of mind. =)
