job descriptions

Hi there.

I am trying to submit a planned job that should look every morning for
certain changes in a couple of tables, and send mails to a few people
advising accordingly.

The application works (I am able to call it from the command line), but the
scheduled job it's giving me some trouble.

This program needs the library 'MMAIL' in the library list to be able to
find a service program it uses during execution. When I run the program
interactively I just 'addlible MMAIL' and be done with it, but I am trying
to figure out how to achieve the same thing with the job scheduler.

My first hunch was that I needed a job description with this library in the
initial library list, so I created the jobd 'IVAN/ILYTEST' with a couple of
work libraries in its initial library list (MMAIL, ALTIDAT, and IVAN), and
to made the scheduled job to use that job description. But it doesn't work
as I expected. (Meaning, I still get the error about not being able to find
the service program).

What's the proper way of accomplishing this?

Thanks in advance for your help.

Regards,

I.-
