RJE/XL Node Manager's Guide

GLOSSARY 

$STDIN:. 
A system-defined file name referring to the standard input "file," which
can be an actual file or a device.  $STDIN often refers to the keyboard
for interactive sessions and a file for batch jobs or programs.  $STDIN
treats a colon (:)  appearing in the first column of input data as an
end-of-file indicator.

$STDINX:. 
Same as $STDIN. However, unlike $STDIN, $STDINX treats the colon (:)
prompt appearing in the first column of input data as part of the data
file, instead of an end-of-file indicator.

$STDLIST:. 
A system-defined file name referring to the standard output "file," which
can be an actual file or a device.  $STDLIST often refers to the terminal
for interactive sessions and the printer for batch jobs.

actual file designator:. 
The file name provided by the user.  The system then uses the file name
in place of the formal file designator to accomplish some task.  The
actual file designator is the file name listed in the directory.  See
also formal file designator.

American Standard Code for Information Interchange (ASCII):. 
The standard method of representing character data (seven data bits plus
one bit that is sometimes used for parity checking).  This method was
established by the American National Standards Institute (ANSI) to
achieve compatibility between data devices when they are interchanging
information.

ASCII:. 
See also American Standard Code for Information Interchange.

batch mode:. 
This mode is initiated when streamed jobs submit RJE commands and data to
MPE for processing.

batch processing:. 
A technique of data processing in which jobs are collected and grouped
before processing.  Data is collected over a period of time, and then
submitted to a host computer.  A job, which is submitted as a single
entity, can consist of multiple commands such as program compilation and
execution, file manipulation, or utility functions.  Once submitted, no
further interaction between the user and the job is necessary.

binary data:. 
A representation of numbers, alphabetic characters, and symbols in
digital computers.  Binary is the base-two numbering system that uses
only two digits, 0s and 1s, to express numeric quantities.

binary synchronous communication (BSC):. 
A data link protocol using binary synchronous line discipline.  This
protocol uses a standardized set of control characters and control
character sequences, for synchronous transmission of binary-coded data
between stations.  Synchronization of characters is controlled by timing
signals generated at the sending and receiving stations.

bisync:. 
See also binary synchronous communication.

blank field compression:. 
Reducing a string of blank characters to a two character sequence.  This
two character sequence consists of an IGS or GS control character
followed by a count specifying the number of blanks being compressed.

BSC:. 
See also binary synchronous communication.

command file:. 
An unnumbered file that contains RJE subsystem commands.  This file
usually cannot contain input data unless it has also been specified as
the input file when RJE is invoked.  Commands are read from the command
file when RJE is in command mode.

Communications Subsystem:. 
A set of intrinsics that RJE uses to communicate with the INP or PSI
card.  Errors that occur during the operation of the INP or PSI card are
reported as CS errors.  On RJE/XL, CS is also referred to as RCS.

compression:. 
The process of translating data into a more compact form so that it can
be transmitted more economically or efficiently.  See also blank field 
compression.

CS:. 
See also Communications Subsystem.

data set:. 
In IBM terminology, any file.

device class:. 
A collection of devices.  The MPE operating system supports a means of
maintaining collections of devices.

Extended Binary-Coded Decimal Interchange Code:. 
An eight-bit code that is a extension of binary-coded decimal (BCD)
notation.  EBCDIC can represent up to 256 different characters.

EBCDIC:. 
See also Extended Binary-Coded Decimal Interchange Code.

end-of-transmission character:. 
A transmission control character used to indicate the conclusion of a
transmission, which may have included one or more texts and any
associated message headings.

EOT:. 
See also end-of-transmission character.

formal file designator:. 
The name that commonly appears on the left side of a file equation for
the purpose of redirecting input/output to or from a file or device, or
defining the characteristics of a file or device.  This is the name that
processes will refer to, rather than to the actual file or device.  See
also actual file designator.

HASP workstation:. 
HASP (Houston Automatic Spooling Program) is the acronym for an early IBM
job entry subsystem.  HASP later became a basis for the JES2 job entry
subsystem.  JES2 refers to devices such as an IBM 2780 or IBM 3780 remote
workstations as HASP workstations.

IBM 2780 workstation:. 
An IBM 2780 Data Transmission Terminal.  This workstation consists of a
control unit, a line printer, a card reader and optionally a card punch,
and is also referred to as a Remote Batch Workstation, or Remote Batch
Terminal.  These workstations are used to send jobs and data to a host
system and receive data from that system.

IBM 3780 workstation:. 
An IBM 3780 Data Communication Terminal.  This workstation consists of a
control unit, a line printer, a card reader and optionally a card punch,
and is also referred to as a Remote Batch Workstation, or Remote Batch
Terminal.  These workstations are used to send jobs and data to a host
system and receive data from that system.

communications overhead including protocol handling, data buffering,
error checking, and responses to polling.

interactive mode:. 
The mode is initiated when RJE is started from the keyboard by one of the
following MPE commands:  :RJE or :run RJE.PUB.SYS. In this mode, the user
has the capability of entering RJE commands from the keyboard.

interrupt mode:. 
The mode is initiated when in programmatic control and a message file has
been specified with the RJLINE parameter, and an RJOUT command with
INTERRUPT=YES has been issued.  In interrupt mode, RJE will execute
command files that have been specified to the message file.

JES2:. 
A common IBM job entry subsystem used under the MVS operating system.

An IBM job entry subsystem used under the MVS operating system that is an
extension of the Asymmetric Multiprocessing System (ASP) program.  JES3,
which supports multiprocessing, receives jobs into the system and process
all output produced by a job.

concurrently submit command files for execution by RJE. This process can
continue for an indefinite period of time.  Also, in programmatic control
mode, RJE will receive an unlimited number of data sets from another
system.
