Code overview:
AG03 - Subfile pgm to show a list of members
Will accept option to print a member
AG01CL - Does overrides and calls AG01
AG01 - Print a source member. Presumes that
the member is pointed to by a prior
OVRDBF
AG02 - "List members" API
The intent is to model somebody converting some OPM code to RPG IV and
starting to build a "WRKMBRPDM" like tool. Currently it accepts only "P" to
print the source. The code is purposely traditional looking.
