NOCONVERT

Message        <Context> "<expression>" is of type "<type>", and
               cannot be converted to "<target type>".

Description    An expression of one type cannot be converted to the
               type required by this expression.  This most often
               occurs when the source type of an assignment or cast
               cannot be converted to the destination type.  The
               rules for which types can be converted are rather
               complicated and differ based upon the compiler mode.
               Refer to the language documentation for a complete
               list of valid combinations.

User Action    Modify the conversion to use valid types.
