RE: Eval Exception Error Trapping

I'll have to look into that.  I've never used before.  I guess it's time to
learn it.

Thank you,

Joe:

Have you investigated the *PSSR internal subroutine?  When an error occurs
(most
of the time), control will transfer to this routine, you can do what you
want
inside the routine (like escape, bypass, return etc.).
