This is a great place to use the Product Library feature of OS/400
commands.   A Product library get's inserted at the beginning of a
commands execution and is automagically removed when the command's CPP
completes.   (If you want to see an example check out your library
list before and after entering the STRPDM command).

IMHO, the most important reason to use Product library in this case is
that it precludes you from having to hard code a library into a CL
program.  I STRONGLY discourage this practice because it makes testing
more complicated and potentially much more dangerous.

For the same reason just listed above (testing), we use JOBD to set
the library list.  It's much easier to configure, doesn't require a
program change everytime you make an adjustment, and best of all,
doesn't require a last minute (untested) program change right before a
program is moved from test to production.
