MRMTRDDR Prolog

 DSECT NAME - MTRDDR
 FUNCTION - Map a Monitor record.
 LOCATED BY -
        Through the Monitor Control Area
 REFERENCED CONTROL BLOCKS -
        MRRECHDR    Monitor Record Header
 NAME - MRMTRDDR
 DESCRIPTIVE NAME - Monitor Event and Sample Configuration Record
                    Domain 1  - Monitor Domain
                    Record 14 - Domain Detail
 DESCRIPTION - A list of devices or userids that are enabled for
               monitoring.  A separate record is generated for
               each applicable event or sample domain.
 NOTES:
 --  The list of items (MTRDDR_DMITEMS) may be spanned across more
     than one MRMTRDDR record.  The flag, MTRDDR_CONT, indicates
     whether the list is continued in the next MRMTRDDR record.
     The record itself will not be spanned across a frame boundary.
     When the spanning of the list becomes necessary, this record
     will be followed by an End-of-Frame record (MRMTREOF, Domain 1,
     Record 13), and the list will be continued in another MRMTRDDR
     record in the next frame.
