Helen,
thanks for this. The fields ARE Char fields - a CHAR (15) and a CHAR
(30). I assume that what you're saying therefore is that IB Objects
now returns Char fields untrimmed? The thing that confuses me about
this is that if you use AsString anywhere outside of the
OnCalculateField event it trims the field fine. If we do have to use
FieldsTrimming I assume we simply use:
FULLNAME=r
to right trim?
TIA,
