COMMAND NAME:

        SYSTEM

USAGE:
        SYSTEM <commands>

        Allows the user to execute operating system commands while
        using the editor.  On systems with a suitable window management
        system, such as Sun's "sunview", a window is created for the
        user to run commands in.  Any arguments are interpretted 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 interactivly terminate the
        window to resume using the editor.  A message in the status
        window is displayed which reminds the user of this fact.

EXAMPLES:

        > SYSTEM
        > SYSTEM  date
        > SYSTEM "rsh gonzo lpr -Pvplot < vw.spool" {spool a plot}

ADDITIONAL INFORMATION:

        The current Sun library routines has problems with creating
        sub-processes which use graphics.  In such cases, it is better
        to run a graphical program, such as LED from a shell window
        in interactive mode, than it is to include LED as part
        of the SYSTEM command.

        Cntrl_C will immediately get rid of the system window.

        The user can 'vi' the help file by hitting the 'v' key,
        provided that the 'hit CR to return' message is not showing.
