File Utility Program (FUP)
attributes. A file system provides the namespace for the file serial numbers that uniquely
identify its files.
File Utility Program (FUP). A Tandem product that allows users to create, copy, purge, and
otherwise manipulate disk files interactively.
fixed-function terminal. A nonintelligent device (that is, a device without processing ability)
capable of sending and receiving information over communications lines. Fixed-function
terminals are often referred to as dumb terminals.
freeze condition. A condition in which communication between a terminal and a server class
is prohibited. See also thaw condition.
front-end process. A process, such as the process that accepts the TCP terminal-data stream,
that serves as the intermediary between one system, process, or device and another.
fully qualified file name. The complete name of a file in the Guardian environment. For a
permanent disk file, this consists of a node name (system name), volume name,
subvolume name, and file identifier (file ID). In interactive interfaces such as
PATHCOM and TACL, the parts of a file name are separated by periods. See also
partially qualified file name.
gateway process. A process, such as the Transaction Delivery Process (TDP) that is part of
RSC, that manages communications between dissimilar environments (for example, a
workstation and a Tandem system). A gateway process both transfers information and
converts it to a form compatible with the protocols used by the destination environment.
GDSX. See Extended General Device Support (GDSX).
graphical user interface (GUI). A type of screen interface that typically includes pull-down
menus, icons, dialog boxes, and online help.
Guardian. An environment available for interactive or programmatic use with the Tandem
NonStop Kernel. Processes that run in the Guardian environment use the Guardian
system procedure calls as their application program interface, and might also use related
APIs such as the Pathsend and TMF procedure calls. See also Open System Services
(OSS).
Guardian environment. The Guardian API, tools, and utilities. See also Guardian.
Guardian operating environment. See Guardian environment.
high PIN. A process identification number (PIN) in the range 256 through 65535. See also
process identification number (PIN) and low PIN.
IDS. See intelligent device support (IDS) facility.
Inspect. The Tandem debugging tool that can be used interactively to examine and modify
the execution of Guardian processes and SCREEN COBOL requester programs.
