How about something like this:
D DS
Dunitsds 1 120 3
D dim(12)
D units1 1 10 3 INZ
D units2 11 20 3 INZ
D units3 21 30 3 INZ
D units4 31 40 3 INZ
D units5 41 50 3 INZ
D units6 51 60 3 INZ
D units7 61 70 3 INZ
D units8 71 80 3 INZ
D units9 81 90 3 INZ
D units10 91 100 3 INZ
D units11 101 110 3 INZ
D units12 111 120 3 INZ
C EVAL unitsds(month) = something
units1...units12 are fields defined in a physical file.
Hope this helps
Mark

Please respond to
RPG400-L
Question:
It would seem to me that he could use either Overlay or a basing pointer
to do the exact same thing, correct?
Which is the more "correct" way to do it? I would be apt to use a basing
pointer to an array and point it to MONTH01, but does Overlay have some
advantage, even if it is easier to maintain.
