--
-- OBJECTIVE:
--      Check that the functionality contained in package
--      Ada.Wide_Text_IO.Editing is available and produces correct results.
--
-- TEST DESCRIPTION:
--      This test is designed to validate the procedures and functions that
--      are found in package Ada.Wide_Text_IO.Editing, the "wide" 
--      complementary package to Ada.Text_IO.Editing.  The test is similar 
--      to CXF3301, which tested a large portion of the Ada.Text_IO.Editing
--      package.  Additional testing has been added here to cover the balance
--      of the Wide_Text_IO.Editing child package.

--      This test is structured using tables of data, consisting of
--      numerical values, picture strings, and expected image
--      result strings.  
--
--      Each picture string is checked for validity, and an invalid picture 
--      string will cause immediate test failure on its first pass through
--      the evaluation loop.  Inside the evaluation loop, each decimal data 
--      item is combined with each of the picture strings as parameters to a
--      call to Image, and the result of each call is compared to an 
--      expected edited output result string.
--
--      Note: Each of the functions Valid, To_Picture, and Pic_String has
--            String (rather than Wide_String) as its parameter or result
--            subtype, since a picture String is not localizable.
--      
--       
-- CHANGE HISTORY:
--      22 Jun 95   SAIC    Initial prerelease version.
--      22 Aug 95   SAIC    Test name changed to CXF3002 (from CXF3401) to 
--                          conform with naming conventions.
--      24 Feb 97   PWB.CTA Corrected picture strings and expected values.
