-- OBJECTIVE:
--    Check that Standard_Output can be flushed.  Check that 'in' parameters of
--    types Ada.Text_IO.File_Type and Ada.Streams.Stream_IO.File_Type can be
--    flushed.  (Defect Report 8652/0051).
--
-- CHANGE HISTORY:
--    12 FEB 2001   PHL   Initial version
--    16 MAR 2001   RLB   Readied for release; fixed Not_Applicable check
--                        to terminate test gracefully.
