through a local channel
attachment or through modems
and phone lines.
Command Interpreter (CI):
The part of MPE which analyzes
and processes commands entered
during a session or submitted as
part of a job.
communications controller: A
type of front-end processor, such
as an IBM 3705, 3720, or 3725,
that communicates between the
communications facility and a
hostcomputer. IBM supportsboth
programmable and
nonprogrammable
communication controllers.
Hewlett-Packard's INP and PSI
are types of communications
controllers.
communications link: The
hardware that directly connects
two locations for the purpose of
data transfer, including the
interface boards, cables, and
modems (if a telephone line is
used).
Control Unit (CU): A device
that controls input and output for
one or more devices such as
printers or display stations.
CU: See Control Unit.
D
data set: In IBM terminology,
any file.
Distributed Processing
Programming eXecutive
(DPPX): A general-purpose IBM
operating system found on the
IBM 8100. DPPX supports a
remote job entry workstation
facility (DPPX/RJE).
Distributed Processing
Programming
eXecutive/Remote Job Entry
(DPPX/RJE) workstation
facility: An IBM 8100 facility
that enables users to submit
batch jobs to host processors and
to receive output.
Hewlett-Packard has developed
products which, when taken
together, emulate many of the
major DPPX/RJE capabilities.
DPPX: See Distributed
Processing Programming
eXecutive.

eXecutive/Remote Job Entry
workstation facility.
E
emulation: A technique, using
software, allowing one computer
to behave exactly like another
computer. A Hewlett-Packard
emulation of an IBM device is an
HP data communications product
that enables an HP computer or
terminal to carry out many of the
functions of the IBM device. For
example, the HP SNA NRJE
product enables an HP computer
