  segmentname After each successful call, IMS places in this method the name of the last segment that satisfied the call. When a retrieval is successful, this method contains the name of the retrieved segment. When a retrieval is unsuccessful, this method contains the last segment along the path to the requested segment that would satisfy the call.
