Chapter 1 Introduction to RJE
Hewlett-Packard's Remote Job Entry (RJE) product allows an HP 3000 system
to emulate the major functions of an IBM 2780 or IBM 3780 workstation.
RJE can transmit batch jobs to and receive output from a host processor
that can support standard IBM 2780/3780 devices. Additionally, RJE can
exchange files between an HP 3000 and many other processors that emulate
standard IBM 2780/3780 devices. RJE, which runs under the control of the
HP 3000 Multiprogramming Executive Operating System (MPE), makes your HP
3000 computer system appear to the remote processor as an IBM 2780 Data
Transmission Terminal or an IBM 3780 Data Communication Terminal.
RJE is more flexible than the IBM terminals it emulates in that it allows
you to use a greater variety of input and output devices, including disk
and magnetic tape.
You can operate RJE in either batch mode (using a streamed job) or
interactive mode (by entering commands from the terminal). Refer to
chapter 4, "Using RJE in Batch and Interactive Mode." Additionally, when
RJE is in programmatic mode, more than one user can submit commands for
execution by a single RJE job or session. Refer to Chapter 5, "Using RJE
in Programmatic Mode."
The RJE commands allow you to control the sequences of input/output
processing. Table 1-1 summarizes these commands:
Table 1-1. RJE Commands
-------------------------------------------------------------------------------------------
| |
| COMMAND FUNCTION |
| |
-------------------------------------------------------------------------------------------
| |
| RJCMDFILE Identifies and transfers control to an |
| alternative command file. |
| |
| RJCOMMENT Allows the user to enter comments within |
| subsystem commands in a job stream. |
| |
| RJCONTINUE Provides a means for user-written |
| procedures to analyze and act upon |
| subsystem errors. |
| |
| RJDEBUG Accesses the MPE V or MPE XL debugger. |
| |
| RJEND Ends the RJE subsystem. |
| |
| RJEOD Transmits an end-of-transmission (EOT) |
| control character to the remote processor |
| after sending the last buffer of data from |
| an RJIN command. |
| |
| RJHELP Displays a help screen showing all of the |
| RJE commands with their parameters and |
| functions. |
| |
| RJIN Transmits input data from your HP 3000 |
| computer system to the remote processor. |
| |
| RJINFO Initiates a display of information on the |
| communications line. |
| |

Table 1-1. RJE Commands (continued)
-------------------------------------------------------------------------------------------
| |
| COMMAND FUNCTION |
| |
-------------------------------------------------------------------------------------------
| |
| RJIO or string beginning with a special Initiates transmission of a one-line |
| character message to the remote processor and |
| receives one data set. |
| |
| RJLINE Defines communications line |
| characteristics. |
| |
| RJLIST Requests and processes routed list output |
| or unrouted output from the remote |
| processor. See the note following this |
| table. |
| |
| RJOUT Requests and processes routed or unrouted |
| output from the remote processor. See the |
| note following this table. |
| |
| RJPUNCH Requests and processes routed punch output |
| or unrouted output from the remote |
| processor. See the note following this |
| table. |
| |
| RJSTAT Provides statistical information about the |
| frequency of subsystem command use, elapsed |
| times, and tallies of data transmitted and |
| received. |
| |
-------------------------------------------------------------------------------------------
NOTE The terms 'routed' and 'unrouted' refer to the presence or absence
of component select codes with output transmitted from the remote
processor. Chapter 3 discusses routed and unrouted output in
detail.
