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.
