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

Register Call Stack Entry Termination User Exit Procedure (CEERTX) API

Will handle those scenarios.

- the job is ended

Not required, as there is no way to keep resources in use past the job ending.

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. )

Does try/finally really? I'm not so sure. What happens if you end a process from task manager.
That'd be the equivilant of ending a job. Does the code in finally really get invoked? May have to
test that...
