Queue model function management headers
CICS® uses the QMODEL headers to access IMS MFS demand-paged messages.
QMODEL headers are not sent by IMS to CICS.
For
SEND/RECEIVE
, the CICS application
program must prepare the QMODEL function management headers in order
to receive demand-paged output from IMS.
Temporary storage function shipping can be used with START/RETRIEVE
.
No EXEC commands exist to support the coding of QMODEL FM headers.
The following QMODEL headers are used for MFS demand paging: - QGET
- Requests a page directly
- QGETN
- Requests the next sequential page
- QPURGE
- Requests termination of demand paging
- QXFR
- Sent with the requested page
- QSTAT
- Sent when QPURGE is received, or when the requested page number is invalid
