COMMAND NAME:

        SYSTEM

USAGE:
        SYSTEM <commands>

        SYSTEM allows the user to execute operating system commands while
running an application.  On systems with a suitable window management system,
such as Sun's "sunview", a window is created in which the
user may execute commands.  Any arguments are interpreted as
a single command to be 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 have problems in creating
subprocesses which use graphics.  Thus, it is better
to run a graphical program, such as LED, from a shell window
in interactive mode, rather than include LED as part of a SYSTEM command.

        Cntrl_C will immediately eliminate the window created by SYSTEM.
