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.
