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

      /CC_COMMAND [=command-line]
      /NOCC_COMMAND
      /CC_COMMAND="CC/G_FLOAT/STANDARD=NOPORTABLE" (default)

        This qualifier is equivalent to the -cc_cmd 'command_line'
        argument in the universal syntax.
