 DSECT NAME - SCLSHR
 FUNCTION - Map a Monitor record.
 LOCATED BY -
           Through the Monitor Control Area
 REFERENCED CONTROL BLOCKS -
        MRRECHDR    Monitor Record Header
 NAME - MRSCLSHR
 DESCRIPTIVE NAME - Monitor Event Record
                    Domain 2 - Scheduler Domain
                    Record 9 - SET SHARE Changes
 DESCRIPTION - Records changes made by a SET SHARE command.
               Generated only if the user who is the target of the
               command is enabled for scheduler domain (not to be
               confused with the user that issued the command).
