     DSECT NAME - APLSDT
     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 MRAPLEDT for
           the buffer/address/length specified by DIAGNOSE 'DC'.
     NAME - MRAPLSDT
     DESCRIPTIVE NAME - Monitor Sample Record
                        Domain 10 - Appldata domain
                        Record 2  - Application Data Sample Record
     DESCRIPTION - Application data as found in the application-defined
                   buffer at the time of this sample interval. A
                   separate record is generated for each buffer
                   declared by the virtual machine(s) via the Diagnose
                   'DC' START operation.
     NOTES:
        -- APLSDT_CALDATOF should always be used to locate the
           APLSDT_ADATA data area. Its value may be subject to change.
        -- Application data in APLSDT_ADATA is as found in the
           application-defined buffer at the time the record was
           generated.
