cpu, pin
cpu, pin . In the Guardian environment, a number pair that uniquely identifies a process
during the lifetime of the process, consisting of the processor (CPU) number and the
process identification number (PIN). See also
PID .
data segment. A virtual memory segment holding data. Every process begins with its own
data segments for program global variables and runtime stacks (and for some libraries,
instance data). Additional data segments can be dynamically created. See also
flat
segment and selectable segment .
DEFINE. An HP Tandem Advanced Command Language (TACL) command you can use to
specify a named set of attributes and values to pass to a process.
disk drive. A device that stores and accesses data on a magnetic disk. Random access to
addressable locations on a magnetic disk is provided by magnetic read/write heads.

disk volume. See word .
distributed system. A system that consists of a group of connected, cooperating
computers.
download. The process of transferring software from one location to another, where the
transferring entity initiates the transfer.
dynamic-link library (DLL). A collection of procedures whose code and data can be loaded
and executed at any virtual memory address, with run-time resolution of links to and
from the main program and other independent libraries. The same DLL can be used by
more than one process. Each process gets its own copy of DLL static data. Contrast
with
shared run-time library (SRL) . See also TNS/R library .
dynamic loading. Loading and opening dynamic-link libraries under programmatic control
after the program is loaded and execution has begun.
earth ground. The connection of the electrical-grounding conductors to a dependable, low-
resistance contact with the soil.
EDIT file. In the Guardian file system, an unstructured file with file code 101. An EDIT file
can be processed by either the EDIT or PS Text Edit (TEDIT) editor. An EDIT file
typically contains source program or script code, documentation, or program output.
Open System Services (OSS) functions can open an EDIT file only for reading.
eld utility. A utility that collects, links, and modifies code and data blocks from one or more
position-independent code (PIC) object files to produce a target TNS/E native object
file. See also
ld utility and nld utility .
ELF. See Executable and Linkable Format (ELF) .
emulate. To imitate the instruction set and address spaces of a different hardware system
by means of software. Emulator software is compatible with and runs software built for
