3    /OUTPUT

       /OUTPUT[=filespec]
       /NOOUTPUT

    Controls where the output of the command is sent. If you do
    not enter the qualifier, or if you enter the /OUTPUT qualifier
    without a file specification, the output is sent to the current
    process default output stream or device, identified by the
    logical name SYS$OUTPUT.

    If you enter the /OUTPUT qualifier with a partial file
    specification (for example, specifying only a directory), SHOW
    is the default file name and .LIS the default file type. If you
    enter a file specification, it cannot include the asterisk (*)
    and the percent sign (%)  wildcard characters.

    If you enter the /NOOUTPUT qualifier, output is suppressed.

    Requires LOG_IO (logical I/O) or PHY_IO (physical I/O) privilege.
