Glossary of Terms
keyed sequential access method (KSAM) A file access method supported on the HP
3000 (and included with the fundamental operating software) in which
records may be accessed either sequentially or randomly by primary or
alternate record keys.
keyword A word assigned a specific meaning by the operating system, a subsystem,
computer language, or utility.
keyword parameters Words that have special meaning to the command interpreter and
are used to modify the intent or effect of an MPE/iX command. Keyword
parameters, unlike positional parameters, may appear in any order after a
command has been entered on the command line. An entire keyword
parameter group, such as PASS=password, must be separated from other
keyword parameters by a semicolon (;).
KSAM64 A new KSAM file type that has the ability to support large KSAM file
sizes.
label table A table that contains file labels for the files residing on the volume set.
LAN 3000/XL LINK Provides the hardware and communications software needed to
connect 900 Series HP 3000 machines to a network for system-to-system
communication.
LAN cables Cables used to connect the Datacommunications and Terminal Controller
(DTC) and the system. See Thick LAN cable and Thin LAN cable.
language construct A command grouping (for example, IF-ENDIF) used to control the

(4,294,901,760) bytes.

laser printing A method of printing in which a rotating drum has a raster image
transferred onto it by a laser. As it rotates further, it is dusted with a fine
black plastic powder called toner which adheres to the drum where it was
struck by the laser. When the drum comes in contact with the paper, the
toner pattern is transferred onto it and the toner is melted (fused) to make
the printing permanent.
layers The division in network architecture models. In network architecture,
different transmission and communications tasks are assigned to each
layer. Each layer is a logically distinct module. One example of layers is
the seven-layer Open Systems Interconnection (OSI) network model
developed by the International Standards Organization (ISO).
LDEV number See logical device number.
library A file containing a set of procedures that may be accessed by programs.
line editor A line editor requires you to press
Return to end one line of text and to
begin another. EDIT/3000 is an example of a line editor.
line printer A hardware device used for system output. A line printer prints output one
line at a time.
