Error handling between ILE modules

[Loyd Goodbar <loyd@xxxxxxxxxxxxxx>]

I have a new ILE program composed of a CLLE driver module and multiple
(SQL)RPGLE modules. It implements a one-way process over data for
first-of-the-month processing; we are automating a manual process. If an
error should occur in any of the modules, I would like control passed to a
module to perform cleanup (displaying the job log, send an email, start
ended subsystems) and abort the program.

What is the best way to go about this? Do I need to write an exception
handler and attach to each module?

Thanks,
Loyd
