Request (input) QMODEL FM headers
The following topics describe the QGETN, QGET, and QPURGE FM headers.
QGETN FM header
A QGETN FM header is received by IMS to cause sequential transfer of a single logical or presentation page of MFS DPM demand-paged output. It is the only QMODEL FM header in the chain and is never followed by function management data.
QGET FM header
Use the QGET FM header as input to IMS to transfer to the next, the last, or any logical page, according to cursor.
QPURGE FM header
When IMS receives a QPURGE header, it halts processing on the demand-paged output message in progress.
