TCP template
TCP template. In a Pathway/XM environment, a template of object settings used to
configure TCPs. See also terminal control process (TCP).
TCP/IP. A communications protocol commonly used for communications between
heterogeneous systems in a multinetwork environment.
TDA. See terminal data area (TDA)
.
TEDIT. A Compaq text editor that runs on NonStop™ Himalaya systems and is used to
create or modify a source text file. Also called PS Text Edit.
tell message. An informational message sent by PATHCOM, PXMCOM, or a management
application to one or more terminals controlled by a SCREEN COBOL program, to be
displayed for the terminal operators.
TELL object. A temporary object used in PATHCOM, PXMCOM, and SPI commands to
define a tell message.
temporary TERM object. A TERM object created by the PATHMON process when a
PATHCOM or PXMCOM RUN PROGRAM command or an SPI START PROG
command is issued. Temporary TERM objects are deleted when application processing
is completed or when a STOP TERM or ABORT TERM command is issued. Names of
temporary TERM objects begin with a number. See also configured TERM object
and
TERM object.
terminal. An I/O device capable of sending and receiving information over communications
lines.
terminal context. Data maintained by a TCP for each active terminal under its control.
terminal control process (TCP). A process used for terminal management and transaction
control, provided as part of the Pathway/iTS 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 the TCP is configured to handle. The TCP coordinates communication between
screen programs and their I/O devices or processes and, with the help of the PATHMON
process, manages links between screen programs and server processes. The TCP also
works with the router process to support connection requests coming from Pathway/iTS
web clients on the internet or IDS requesters using the raw sockets protocol. See also
requester
, SCREEN COBOL, Pathway/iTS web client, and router process.
terminal data area (TDA). In SCREEN COBOL, the area that the TCP allocates for
terminal context data. The MAXTERMDATA parameter of the PATHCOM SET TCP
command or the PXMCFG SET TCP statement defines the upper limit for this data area.
terminal group. A set of TERM objects in a Pathway/XM environment that is defined by a
name and can be managed as a group. When a PXMCOM command is given a group
name in place of a TERM object name, PXMCOM applies the command to all TERM
objects in the group. See also server group
.
