/sys$common/syshlp/helplib.hlb SHOW, NETWORK, Qualifiers, /OUTPUT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /OUTPUT[=filespec]
       /NOOUTPUT

    Controls where the output of the command is sent. By default,
    the output of the SHOW NETWORK command is sent to the current
    SYS$OUTPUT device (usually your terminal).

    The asterisk (*)  and the percent sign (%) wildcard characters
    are not allowed in the file specification.

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