VMS Help DCE_IDL, DCL Command Interface, QUALIFIERS, /CLIENT_FILES  *Conan The Librarian (sorry for the slow response - running on an old VAX)

     /CLIENT_FILES [=(option[,...])]
     /NOCLIENT_FILES

        Specify one or more of the following options.

        ALL (default)
        [NO]AUXILIARY [=filename]
        NONE
        [NO]STUB [=filename]

        This qualifier is equivalent to the -client argument
        in the universal syntax.
