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.
