 Message        The identifier exceeds the SCA limit of <number>
                characters.  In the SCA file the name will be
                truncated to "<truncated spelling>".

 Description    The length of an identifier supported by SCA is less
                than the length of an identifier supported by the
                Compaq C compiler.  Because of this, the compiler
                will truncate an identifier name to fit the SCA
                limits.

 User Action    Either reduce the identifier name, or be aware of
                this when using SCA.
