VMS Help CC, Messages, REGNOSHARE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        <Context> noshare cannot be used with the register
                storage class.  Modifier noshare is ignored.

 Description    The storage class modifier noshare is meaningless for
                objects declared with register storage class.  The
                compiler ignores the noshare.

 User Action    Remove the noshare storage class modifier.
