Introduction
A Workstation
A batch workstation is known to the host as a combination of one or
more of the following peripheral devices, or their equivalents:
• Card Readers
• Line Printers
• Card Punches
• Operator Console
It is identified by RMT
nnnn which represents the remote workstation
number.
Jobs are submitted from a remote workstation through card readers, or
their equivalent, over a communication line to a host system.
Output is received from a host system over a communication line to
card punches and line printers, or their equivalent, at a remote
workstation.
An operator console at a workstation allows interaction with a host
system by transmitting job entry subsystem commands and by
receiving job entry subsystem messages. An operator console at a
workstation cannot be used for an interactive session with a host
system. Job entry subsystem commands can display information and
can control the following:
• Remote workstation sessions at a host system
• Jobs operating at a host system
• Input and output queues
Primitive Workstations
A primitive workstation requires an operator. All jobs must be
submitted by an operator, all output is received by an operator, and an
operator executes all console commands and receives all console
messages.
Advanced Workstations
Advanced workstations are designed to allow users other than the
operator to perform the following tasks:
• Submit a job to a transmission queue
• Display information about jobs in a transmission queue
• Modify a transmission queue
• Receive job output data into output queues
• Modify output queues
