RE: Change Column Heading for a field

["Raikov, Lo" <RaikovL@xxxxxxxxxx>]

Oh, that I understand. As long as record format does not change (and level
id is the record format attribute, isn't it?) everything is fine. I just got
an impression from Al's message that IBM had all but annihilated level
checks for DB files. Sorry, I probably read into it more than the message
actually contained.
