     DESCRIPTION - Provides measures of overall communications
                   activities for IUCV and VMCF. A separate record
                   is generated for each online processor.
                   "Data Transferred" by IUCV includes IUCV SEND
                   and IUCV REPLY.  It does NOT include the IUCV
                   RECEIVE function.
