RE: Help me with my homework--I mean this subprocedure

["Wilt, Charles" <WiltC@xxxxxxxxxx>]

The problem with this idea is that you're required to have one for each field you need to do this to.

Where as with Mike's procedure, you write it once and then just:

Pfld1 = GetPrintVal(Ffld1:%len(pfld1):%decpos(pfld1));
Pfld2 = GetPrintVal(Ffld2:%len(pfld2):%decpos(pfld2));
Pfld3 = GetPrintVal(Ffld3:%len(pfld3):%decpos(pfld3));
