/sys$common/syshlp/helplib.hlb CC, Messages, COMMANDMACRO  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        Extraneous text "<text>" at the end of the command
                line macro "<macro>" is ignored.

 Description    A command line macro define contains an invalid macro
                name.  The compiler will define the macro name listed
                in the message.

 User Action    Correct the command line invocation.
