1.2 RJE Features

SNAP-IX RJE provides the following features (explained in more detail in RJE Components and Operation):

Multiple RJE workstations

You can configure each RJE workstation for use by a group of users. SNAP-IX supports multiple RJE workstations on a single SNAP-IX system, enabling you to provide different RJE configurations to suit the requirements of different groups of users.

Local queueing of jobs

Jobs submitted for a host are queued locally on a spool before being sent to the host. SNAP-IX provides programs to submit jobs to an RJE workstation, to list the jobs spooled for the workstation and check their status, and to cancel a job spooled for the workstation. SNAP-IX also provides optional facilities to save status information about sent jobs, so that you can check that a job has been sent, and to purge the stored status information.

Multiple printers and punches per workstation

Each RJE workstation can support up to nine printers and nine punch output devices. They can be used in conjunction with the host configuration to provide different output handling for different types of data.

Disk and program output

Host output can be routed to a disk file or can be piped as standard input to a program or shell script for processing.

Host console program

A full-screen console program enables you to view host console information for an RJE workstation and to issue commands to the host job entry subsystem.

PDIRs

SNAP-IX accepts Peripheral Data Information Records (PDIRs) from the host. These can be stored in a file associated with the output or can be passed as parameters to a program that processes the output.

Code conversion

Data can be translated from ASCII to EBCDIC when sending to the host, and from EBCDIC to ASCII when receiving output from the host, or can be sent or received as binary data without code conversion.

Modifiable data record size

In addition to the normal record lengths of 80 bytes for punch data and 128 bytes for exchange data, SNAP-IX enables you to send and receive data in records of any size from 80 bytes to 248 bytes. The use of exchange data and record lengths other than 80 bytes is dependent on the ability of the host system to support them.

Inbound and outbound compression

SNAP-IX provides support for compression both when transferring data to the host and when receiving data from the host. The use of compressed data is dependent on the ability of the host system to support it.

Multiple LUs per workstation

You can define each RJE workstation to use up to five LUs, so that the workstation can perform multiple operations at the same time (for example, sending jobs to the host and receiving host output).
