--
-- OBJECTIVE:
--      Check that characters in Latin-1 above ASCII.Del can be used in
--      identifiers, character literals and strings.
-- 
-- TEST DESCRIPTION:
--      This test utilizes the brackets scheme for representing Latin-1
--      character values in transportable 7 bit ASCII as proposed by
--      Robert Dewar; this test defines Character and String objects,
--      assigns and tests several sample values.  Several Identifiers
--      used in this test also include Characters via the bracket escape
--      sequence scheme.
--
--      Note that C250001 checks Wide_Characters and Wide_Strings.
--
-- SPECIAL REQUIREMENTS:
--
--      This file must be preprocessed before it can be executed as a test.
--
--      This test requires that all occurrences of the bracket escaped
--      characters be replaced with the corresponding 8 bit character.
--
--      Characters above ASCII.Del are represented by a 6 character sequence:
--
--          ["xx"]
--
--      where the character code represented is specified by two hexadecimal
--      digits (<xx>) upper case. For example the Latin-1 character with the
--      code 16#AB# is represented by the six character sequence:
--
--          ["AB"]
--
--      None of the values used in this test should be interpreted as
--      a control character.
--
--      The following function documents the translation algorithm:
--
--     function To_Char( S:String ) return Character is
--       Numerical : Natural := 0;
--       type Xlate is array(Character range '0'..'F') of Natural;
--       Xlation : Xlate
--               := ('0' =>  0, '1' =>  1, '2' =>  2, '3' =>  3, '4' =>  4,
--                   '5' =>  5, '6' =>  6, '7' =>  7, '8' =>  8, '9' =>  9,
--                   'A' => 10, 'B' => 11, 'C' => 12, 'D' => 13, 'E' => 14,
--                   'F' => 15,  others => 0 );
--     begin
--       for I in S'Range loop
--         Numerical := Numerical * 16 + Xlation(S(I));
--       end loop;
--       return Character'Val(Numerical);
--     end To_Char;
