     DSECT NAME - SCLSCA
     FUNCTION - Map a Monitor record.
     LOCATED BY -
               Through the Monitor Control Area
     REFERENCED CONTROL BLOCKS -
            MRRECHDR    Monitor Record Header
     NAME - MRSCLSCA
     DESCRIPTIVE NAME - Monitor Event Record
                        Domain 2  - Scheduler Domain
                        Record 12 - SET CPUAFFINITY changes
     DESCRIPTION - Records changes made by a SET CPUAFFINITY command.
                   Generated only if the user who is the target of the
                   command is enabled for scheduler domain (not to be
