Here's a moodified version of a program our menu system uses to add and
remove libraries as they are needed. In our situation, this program is
called, and is passed a parameter to indicate 'wakeup' or 'shutdown.'
This version should be fine as an in-line program.
The code to 'retrieve the real name of this program' was sponged from an
IBM menu generator way back in the dim ages of the S/38. The idea is that
you can have a whole bunch of programs that save their LIBLs, each tracking
just the changes it made.
This program retrieves the LIBL as it exists right now, and saves it to a
data area it creates in QTEMP. You then mutilate the LIBL, adding and
removing libraries as needed. Now call your application's first menu.
When you're done with your application, RETURN to this program, which will
retrieve the LIBL from the data area, change your job's LIBL back to what
it was to start with, and exit.
One note about the 'mutilate your LIBL here' section. I recommend just
adding and removing libraries. Do not replace the LIBL in its entirety.
If your shop has any libraries that -you- require, replacing the entire
LIBL would remove those, too!
