Problem with Date Data Type Translations

We have the next problem:

 We works with Oracle RDBMS 6.0.34.3.2, Do you remember it?.  Database language is Spanish_spain.we8dec, and user language variable too.  With SQL*Forms 3.0.16.4.3, when we use TO_CHAR or TO_DATE functions don't  work correctly with Spanish language.

 SQL*Forms reads correctly a date variable in spanish but when we use TO_CHAR  to convert it then we get it in english.

 Example:

           fecha is date.
           fecha = '14-dic-95';  ( DECember -> in spanish -> DICiembre )
          MESSAGE(TO_CHAR(fecha,'dd-mon-yy'));
           and result is:
             14-dec-95
