similarly for other fields
ReDim FieldList((FieldCount + UBound(FieldInfo) + 1) * Len(FieldInfo(0)) - 1)
Call CopyMemory(FieldList(0),FieldInfo,Len(FieldInfo))
lRetVal=gPDb.ModifyDataDefinition(DataDefId,DataDefName,DataDefComment,Unused,FieldCount,FieldList)
if lRetVal <> NG_SUCCESS Then
MsgBox gPDb.ErrDescription, vbInformation
