EXCEPT & *PSSR

I retrofit an old program with a *PSSR to serve as a generic error
handler. Today, the program encountered a duplicate key error on an EXCEPT
to a program-described file. It raised an unhandled exception without
hitting the *PSSR.

Is there a way to get the *PSSR to handle this? The program is rife with
unnamed EXCEPT conditioned on a large number of different indicators, and
I'd rather not have to trap for exceptions on every EXCEPT.


TIA
