PSSR -PROGRAM STATUS SUBROUTINE
In RPG, there are Program Exception/Errors (divide by zero, array index error, etc.)
and File Exception Errors (any file error). As with MONMSG in CL, you can trap errors
at the program level or the command level.

Program Exceptions:
If a program encounters a program error, it checks to see if there is a *PSSR subroutine coded in the program. If there is, it executes the subroutine. If there isn't, the program "fails" with an error message.
A *PSSR subroutines may be executed like any other subroutine (using ExSR or CASxx). The EndSR for a *PSSR subroutine can contain a return-point instruction.
