     DSECT NAME - SYTXSP
     FUNCTION - Map a Monitor record.
     LOCATED BY -
            Through the Monitor Control Area
     REFERENCED CONTROL BLOCKS -
            MRRECHDR    Monitor Record Header
     NAME - MRSYTXSP
     DESCRIPTIVE NAME - Monitor Sample Record
                        Domain 0 - System Domain
                        Record 5 - Expanded Storage Data (per processor)
     DESCRIPTION - Assesses use and benefits derived from expanded
                   storage. A separate record is generated for each
                   online processor. This information should be used
                   with record MRSYTXSG (Domain 0, Record 14) for a
                   complete picture of expanded storage use.
