RE: DoU...

Jim,

Instead of using READ, use READE with a KLIST that only has the two parts of
the equipment number.  That way, you don't have to check when you run out of
records with a matching equipment number.  Or you could define a logical
with all proper fields to check against and then just do a SETLL to check
whether the record already exists.
