RE: Starting out with sub-procedures

JT

  >> But if the procedure is written in another language, then those
languages do not have a PI defined so there is no checking until run time.

All languages have the equivalent of a PI (RPG's *ENTRY PLIST is the same
thing with different syntax) but not all have prototyping - notably CL and
COBOL do not.

The real problem with this statement however is "there is no checking until
run time".  Leave out the words "until run time" and the statement is
accurate.  i.e. "there is no checking".  The reason that prototyping is
valuable is _because_ there is no run time checking of parms.  Only nasty
explosions if you are lucky, and corrupted data if you are not.
