 FUNCTION - Map a Monitor record.

 NAME - MRSYTSXP
 DESCRIPTIVE NAME - Monitor Sample Record
                    Domain 0  - System Domain
                    Record 22 - System Execution Space
                                (Per Processor)
 DESCRIPTION - Utilization of System Execution Space storage on a
               per processor basis.
               This record is needed because System Execution Space
               usage is not expected to be evenly distributed across
               all processors in a complex. A separate record is
               generated for each online processor.
