     DSECT NAME - MTREND
     FUNCTION - Map a Monitor record.

               Through the Monitor Control Area
     REFERENCED CONTROL BLOCKS -
            MRRECHDR    Monitor Record Header
     NAME - MRMTREND
     descriptive name - Monitor Event and Sample Record
                        Domain 1  - Monitor Domain
                        Record 11 - Interval End
     DESCRIPTION - Last record generated for each interval. It is
                   also generated as the last record in the initial
                   set of configuration records. It signals to the
                   processing program that all preceding data (back
                   to the previous interval end) constitutes a
                   complete summary of the previous interval, based
                   on the currently active domains.
