RETURN (RETRN) is required for an RPG to end when *INLR is not turned on.
Tuening *INLR *ON is sufficient to end a program—RETRN is not needed here.

Personally, I prefer to use IF, FOR, DO, WHILE blocks rather than tags and
GOTOs, etc. Although it is often done, I don't think there's a _need_ to
use multiple return points, which, IMHO, are thinly veiled "GOTO's to a
labeled ENDPGM".

Do I hear the mob advancing on this thread?
