The "Standard" also disallows GoBack - and if you asked (IBM) mainframe people
to "give that up" because it was "abuse" - you would be in REAL trouble.

Also, COMP-5 (and COMP-3 and COMP-4) are all "abuse" by this definition.

So is POINTER (in the '85 Standard) and "SET ADDRESS OF" a data-item WITHOUT the
"BASED" clause.

So is REDEFINES of the "non-original" data item.

So is CALL using of a "group-item" that isn't an 01-level (until the '02
Standard).

Should I go on?

I understand the "claim" that many (possibly even MOST) COBOLprogrammers don't
understand the difference between a CONTINUE and a NEXT SENTENCE. Furthermore,
I understand that having a NEXT SENTENCE in the *same* IF as an END-IF (or
SEARCH with END-SEARCH) may not be portable.

HOWEVER, for shops that "suipport" both NEXT SENTENCE (with END-IF) and
CONTINUE, the difference IS "well understood" - and maintainable.
