MRAPLSDT Prolog

 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.
