RE: Matching Records

From: Booth Martin

Why not select?

select
when *INMR and FILE1DS = FILE2DS
* (do nothing)
when *INMR
write MR_Diffs
when *IN01
write NMR_01
when *IN02
write NMR_02
endsl

Isn't that about all of the choices that there are?

Close, except the comparison of non-key fields is only valid when both
records are read in, which only happens when *IN02 is on.

select
when *IN01 and not *INMR
write NMR_01
when not *INMR // *IN02 is implied
write NMR_02
when *IN02 and FILE1DS <> FILE2DS // *INMR is implied
write MR_Diffs
endsl

You ignore primary matching records entirely because you can't see the
secondary fields yet. You only process secondary records if the data fields
don't match.
