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.
