operating software (FOS) for the 900 Series HP 3000.
WARMSTART The process of restarting the HP 3000 by loading MPE V/E from the
system disk. A WARMSTART is used if incompletely processed spooled
jobs and spooled files must be recovered, since other startup options do not
permit the recovery of spoolfiles. MPE/iX equivalent is the START
RECOVERY option of the ISL START utility.
WELCOME message The message that appears when a user logs on to the system.
wildcard A symbol that represents a variety of characters. In MPE, the at sign (@),
the pound sign (#), and the question mark (?) are used as wildcard
characters. Other subsystems may use different symbols.
window A portion of a file or image displayed on selected portions of a CRT screen.

3000. A word consists of 16 bits (2 bytes) of information in other HP 3000
systems.
word processor A program that creates, stores, recalls, and edits text (used for letters,
memos, reports, and other documents).
work around A "scratch file" used for intermediate data storage by a subsystem or
program. It is usually purged when the subsystem or program terminates.

of a permanent disk file. Any changes to the work file are lost unless the

transmission. XON starts data transmission and XOFF stops it.
X.25 A type of communication link that provides connection of packet switching
networks (PSNs), also known as value added networks (VANs). X.25 links
are useful for long-distance communication and can be more economical
than leased lines in some applications.
