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.
