TGroupPosInd and TGroupPosInds indicate the position of the current record within its group.
TGroupPosInd = ( gbFirst, gbMiddle, gbLast );
enum TGroupPosInd { gbFirst, gbMiddle, gbLast };
TGroupPosInds is a set that indicates where the current record sits within a group of records. It is a set because if the group contains only one record, the current record is both first and last.
The following table lists the possible TGroupPosInd values:
