 DESCRIPTIVE NAME - Monitor Event Record
                    Domain 4  - User Domain
                    Record 13 - CPU Pool Change
 DESCRIPTION - Records all changes made to a user's CPU pool
               whether made by a SCHEDULE command, LOGOFF,
               or a user relocation (VMRELOCATE command).
               A user who is assigned to a CPU pool and is
               relocated to another system will generate a
               D4R13 LOGOFF/VMRELOCATE remove record on the
               source system when he leaves that CPU pool
               and will generate a D4R13 SCHEDULE/VMRELOCATE
               ADD record on the destination system when
               he joins that CPU pool.
               Generated only if the user who is the target
               of the command is enabled for user domain
               (not to be confused with the user that issued
               the SCHEDULE or VMRELOCATE command).
