COMMAND NAME:

        SYSTEM

USAGE:
        SYSTEM [commands]

        Allows the user to execute operating system commands while
        using the simulator.  A window is created for the user to
        run commands in.  Any arguments are interpreted as a single
        command and executed.  Otherwise a standard operating
        system window "shell" window is created for the user to
        execute as many commands as desired.

        In either case, the user must interactively terminate the
        window to resume using the simulator.  A message in the status
        window is displayed which reminds the user of this fact.

        Cntrl_C will immediately get rid of the system window.

EXAMPLES:

        sim> SYSTEM
        sim> SYSTEM  "date"
        sim> SYSTEM "rsh gonzo lpr -Pvplot < vw.spool" /* spool a plot */
