In RPG if an *escape message is sent to a procedure lower on the

I won't argue that it isn't as feature rich, but could you provide an
example of the ON-ERROR not be executed? I use MONITOR *a lot* in my code
to pass custom errors.

your monitor code will not run in the following situations:
- you call a COBOL program and it uses STOP RUN to exit.
- the called procedure sends an *ESCAPE message back to the caller
of your procedure
- the job is ended

you want your exception handling code to handle all exceptions. try
finally does that. monitor end-mon does not. ( actually I am not sure
if try finally does handle all exit situations. I just know that
monitor ... end-mon does not. )
