OUTTYPELEN

Message        <Context> this argument to <function name> is of
               "<typeclass>" type and is not appropriate for the
               conversion specifier "<incorrect conversion>".  The
               value might be truncated or formatted in an
               unintended manner.

Description    The compiler has detected an output conversion
               specifier that does not match its corresponding
               argument.  This might not have been what you
               intended.

User Action    Modify either the argument or the conversion
               specifier so that they match.
