Subject: Re: how to create logical file with one key over two fields

Well, if you aren't insisting on being able to read it in RPG with CHAIN
or READ but are open to embedded sql then it's quite easy to do
select * from masterfile where (UPC1=:UpcVariable or UPC2=:UpcVariable)
You'd get better performance if there were two indexes over masterfile.
One by UPC1 and one by UPC2.
