MRMTREND Prolog

 DSECT NAME - MTREND
 FUNCTION - Map a Monitor record.
 LOCATED BY -
         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.
