Inspect command terminal
Inspect command terminal. The terminal on which programmers enter commands to
Inspect when debugging a SCREEN COBOL program or a Pathway server.
intelligent device. A device such as an automatic teller machine, a point-of-sale device, or a
communications line, or a process such as a Guardian process, that can communicate
with the Pathway environment through the intelligent device support (IDS) facility, the
Remote Server Call (RSC) product, or the Pathsend procedure calls.
intelligent device support (IDS) facility. A feature of the TCP that supports access to
Pathway server classes by intelligent devices. This facility allows SCREEN COBOL
requester programs to interact with external processes that, in turn, control devices such
as personal computers, automated teller machines, and point-of-sale devices.
intelligent mode. An operating mode in which data and messages are sent between an
intelligent device and the Pathway environment. See also conversational mode
(definition 1), intelligent device, and message-oriented requester.
interactive mode. An operating mode in which commands are entered from a terminal
keyboard.
interoperability. The ability to communicate, execute programs, or transfer data between
dissimilar environments.
interoperate. To communicate, execute programs, or transfer data between dissimilar
environments.
interprocess communication (IPC) message. The unit of communication between
requesters and servers. An IPC message consists of a request message and a reply
message.
I/O process. In the Guardian environment, a system process to manage input/output devices.
Applications use the Guardian file system to send requests to I/O processes. See also file
system.
IPC message. See interprocess communication (IPC) message.
keyword. A word in a command string or programming language that must be spelled and
positioned in a prescribed way, usually to indicate the meaning of an adjacent parameter.
library. A set of related files or common files that can be accessed by multiple programs or
processes.
linear expandability. See scalability.
link. (1) An open of a server process within a server class. When a link manager—that is, a
TCP or a LINKMON process—sends a request to a PATHMON process for a link to a
server in a specified server class, the PATHMON process selects a server process in that
server class (possibly starting a new server process if necessary) and then returns the
name of the server process to the requesting link manager. See also link granting and
link manager. (2) To examine, collect, associate together, and modify code and data
