In CICS

QMF runs as a conversational transaction in CICS where there are multiple users of QMF in the same CICS address space. Each user that runs a QMF transaction requires at least 1.0 MB of storage from the CICS region. You can allocate all but 24 KB to storage above 16 MB. You can place a single copy of the QMF module, up to 2.7 MB, in the EPLPA or within the CICS region above 16 MB, and you can place 52 KB in PLPA or within the CICS region below 16 MB.
