Then you'll enjoy RPG IV in V5R2 which introduces the concept of
array data structures. These are sort of like MODS's, but you
explicitly code the index. Thus, you can refer to multiple
occurrences (or elements) in the same expression. That makes one
fewer reason for using pointers!  ;-)

Well, that's something to look forward to and something that I will
definitely take advantage of, however we no longer have our own AS/400 but
run on ones at corporate, so I have no control over when the systems are
upgraded from V5R1 to V5R2. :(

The first program that I wrote which needed the simultaneous access to real
data (because it updates both occurrences) was written on V4R4.  I'm
working on a program now which I thought was going to need it, but because
of some database changes I'm making, I'm pretty sure that will not be
necessary.

Enjoy your time off with your family.
