Use this call when a Field in a result set specifies a record in a different Content Definition. For instance, if you open a ContentSet with People, you can call OpenCSJoin on the OrganizationID field and a result set is returned with a row from the Organizations content that matches the persons record.
CSPointer = Call ccLib.OpenCSJoin( CSPointer, FieldName )
CSPointer - Long Integer, pointer used to identify the result set.
