MRAPLEDT Prolog

 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.
