The STOP command.                                  18-MAY-81
          --- ---- --------


             The STOP command provides a useful alternative to the ABORT
        command.  Its function is to abort all tasks that are running at
        the issuing terminal regardless  of  their  task  name.   Hence,
        where a user could type

             ABO F4P

          or

             ABO PIP

          the STOP command (with no parameters) in the form

             STOP

          will accomplish the same function, without having to  type  in
        the  name of the task you want to abort.  All tasks, except STOP
        itself and MCR, will be aborted  and  will  produce  the  normal
        termination message.  If issued in a batch job, the STOP command
        will cause the job to terminate.

             Please do not use the STOP command if  you  are  running  a
        program  that  plots  on the Printronix printer/plotter, and the
        program has finished, but the plot is in progress or has not yet
        appeared.   This action will leave you with a large work file on
        disk and will prevent the system from printing  any  more  print
        jobs until the LPSTART command is issued from TT0:.

             For various reasons connected with  the  operation  of  the
        system, the STOP command will have no effect from TT0:  or CO:.
