Glossary of Terms
standard input.
$STDINX Same as $STDIN. However, unlike $STDIN, $STDINX treats the colon (:)
prompt appearing in the first column of input data as part of the data file,
rather than an end-of-file indicator.
$STDLIST A system-defined file name referring to the standard output "file" (which
can be file or a device). $SDTLIST often refers to the terminal for
interactive sessions and the printer for batch jobs. See standard output.
stop bits When two computers communicate information over an asynchronous
connection, the sending computer adds one or more stop bits to the end of
each byte that it sends. The stop bits tell the receiving computer that an
entire byte has been sent and that a separate byte is on its way.
storage device A device (such as a disk pack, a disk cartridge, a flexible disk, magnetic
tape, or cartridge tape) onto which data can be stored and subsequently
retrieved.
STORE 1. The process of saving HP 3000 files to tape or serial disk. Storing is
executed by using the STORE command.
2. A machine instruction that tells the CPU to take information from a
register and put it in memory.
store-and-forward A method of forwarding messages in a network. In a
store-and-forward network, a node can send a message to another node to
which there is no direct link. Intermediate nodes can forward the message
to the correct destination node. Messages can be stored and forwarded
between several nodes.
stream To execute a batch job by using the MPE STREAM command.
stress testing To test a system by executing a maximum load, over time, to verify that
the system will continue to operate given maximum levels of interactive
and batch processing.
string A point-to-point network topology. The string topology requires fewer
communication links than there are computers in the network, and
requires the fewest number of links. For communication between
non-adjacent nodes, messages are stored and forwarded by intervening
nodes. If a link fails, the nodes separated by the failure are not able to
communicate.
Structured Query Language (SQL) The industry standard relational database
language.
subdividing data A way of limiting access to data by grouping data into volumes,
volume classes, and volume sets.
subline A portion of the command line that occurs only if the command was
continued on the input line by terminating it with an ampersand. Also
referred to as a continuation line.
subqueue priority The priority of a job, session, or system process, with the five system
queues (A, B, C, D, or E). The subqueue priority determines the priority of
