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

 Message        <Context> the promoted type of <name> is incompatible
                with the type of the corresponding parameter in a
                prior declaration.

 Description    The promoted type of a parameter of an old-style
                function declaration does not match the type given
                earlier in a prototype declaration of the function.

 User Action    Correct the data types so they match.  Compaq also
                recommends that old-style function definitions be
                replaced by prototype-format definitions.
