MONITOR performance

I thought I had seen this discussed recently, but couldn't find it after 
searching
the archives for about 30 minutes.

Have a need to catch decimal data errors so that the program can handle it 
without
crashing.  When I suggested using MONITOR and trapping errors that way, a 
colleague
offered that the *PSSR might be a better performer.  I'd like to avoid PSSR 
because
MONITOR seems to offer better recovery options, so that processing can 
continue. 
The program in question is a RCVJRNE exit program.

This is an error that we expect will nearly never happen, but if it does, 
crashing
the program is "not an option" the client can live with.  The error did happen 
in
testing yesterday under circumstances that we don't expect to see in 
production, but
that we can't rule out either.

That said, the solution should provide the same performance as if a DDE never
occurs.  I.e., the MONITOR group or the *PSSR should never impact performance 
when
there is no DDE.

TIA, GA
