     DSECT NAME - APLEDT
     FUNCTION - Map a Monitor record.
     LOCATED BY -
            Through the Monitor Control Area
     REFERENCED CONTROL BLOCKS -
            MRRECHDR    Monitor Record Header
     NOTE: The length of the record must be the same as MRAPLSDT for
           the buffer/address/length specified by DIAGNOSE 'DC'.
     NAME - MRAPLEDT
     DESCRIPTIVE NAME - Monitor Event Record
                        Domain 10 - Appldata domain
                        Record 1  - Application Data Event Record
     DESCRIPTION - APPLDATA domain monitoring has ended for the buffer
                   of the specified application product/release id for
                   one of the following reasons:
                   - A Diagnose 'DC' STOP has been issued
                   - A virtual storage reset is detected (this includes
                     FORCE and LOGOFF)
                   - A purge segment occurs and it is determined that an
                     application buffer resides within the address range
                     of the segment being purged, and the segment
                     resides outside the user's virtual storage.
     NOTES:
        -- APLEDT_CALDATOF should always be used to locate the
           APLEDT_ADATA data area. Its value may be subject to change.
        -- Application data in APLEDT_ADATA is as found in the
           application-defined buffer at the time the record was
           generated.
