MRSYTXSP Prolog

 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.
