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

       /OUTPUT[=filespec]
       /NOOUTPUT

    Controls where the output of the SHOW ENTRY command is sent.
    By default, the output is sent to the current SYS$OUTPUT device
    (usually your terminal). To send the output to a file, use the
    /OUTPUT qualifier followed by a file specification.

    The asterisk (*)  and the percent sign (%) wildcard characters
    are not allowed in the file specification. If you enter a partial
    file specification (for example, specifying only a directory),
    SHOW is the default file name and .LIS is the default file type.

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