Craig,
interesting I thought NUMPROC(PFD) would cause an abend but PACK wouldn't
get a data exception (0C7).

There does not appear to be a combination of NUMPROC and OPT that will
cause
an abend.
NUMPROC(PFD) tells the compiler all your numeric display
and packed-decimal (comp-3 for you old timers) fields
have valid signs; the compiler takes you at your word
and uses non-packed decimal instructions whenever possible
(because they are generally faster). So a MOVE of such
data will generate an MVC, which will never S0C7, instead
of a ZAP, which can S0C7; separate issue: and of course,
PACK never gets a S0C7; if you have bad data, its the use
of packed decimal arithmetic or editing operations on bad
data that can S0C7 (and, of course, CVB if that's
generated along the way).
Kind regards,
