- QSAM
- See queued sequential access method (QSAM).
- qualified call
- A DL/I call that contains
at least one segment search argument.
- quasi-reentrant
- The attribute used to describe CICS application programs that run under the
CICS quasi-reentrant task control block (QR TCB). CICS obtains a separate
copy of program working storage for each task that executes application program
code. Only one task can execute application program code at a time. CICS can
ensure the necessary serialization of user application programs that access
any kind of shared resources, whether CICS- or user-managed, to stop different
tasks from interfering with each other. The user application program need
not be reenterable strictly according to the DFSMS program management definition.
See also reentrant, reentrable.
- queue

- queued sequential
access method (QSAM)
- An extended version of the basic
sequential access method (BSAM) that forms a queue of input data blocks that
are awaiting processing or of output data blocks that are awaiting transfer
to auxiliary storage or to an output device.
- Queue Manager

of CICSPlex SM that creates and manages queues of data in a cache that is
shared by a CMAS and its local MASs.
