subprogram
subprogram. See called program.
subscript. An occurrence number represented by either an integer, a data-name optionally
followed by an integer with the operator + or -, or an index-name optionally followed by
an integer with the operator + or -, that identifies a particular table element.
subvolume. A logical subdivision of a volume, used to group files on the volume.
switch-status condition. The proposition, for which a process can determine a truth value,
that an implementor-defined switch is set to ON or OFF.
symbolic-character. A user-defined word that specifies a user-defined figurative constant.
sync-id. A numeric identifier, assigned by the operating system to write requests in a fault-
tolerant process pair, used to keep track of the requests to prevent the repetition of
requests that cannot be tried again after a takeover by the backup process.
system file name. The name by which the operating system recognizes a file. Compare to
COBOL file name.
system-name. A COBOL word that a process uses to communicate with the operating
system.
system services. The tasks performed on behalf of the user or user programs by the
operating system, including formatting, process control, I-O support, performance
measurement, HP process pair support, standard security, and transaction
management.
table. A set of logically consecutive data items defined in the Data Division by a data
description entry that includes an OCCURS clause.
table element. A data item that belongs to a set of repeated items comprising a table.
TACL. See HP Tandem Advanced Command Language (TACL)
.
TAL. See HP Transaction Application Language (TAL)
.
target file. An object file that is output by the compiler or the Binder or nld utility or ld
utility (as opposed to an object file that is input to the Binder or linker).
TEDIT. An abbreviation for PS Text EDIT, an HP text-editing program.
terminal. An input-output device.
terminal control process (TCP). A process used for terminal management and transaction
control, provided by HP as a part of the Pathway/TS product. A TCP is a multithreaded
process that interprets compiled SCREEN COBOL requester programs (screen
programs) in the user’s application, executing the appropriate program instructions for
each I-O device or process for which the TCP is configured. The TCP coordinates
communication between screen programs and server processes.
