-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained

-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR

--*
--
-- OBJECTIVE:
-- Check that wide character literals are supported.
-- Check that wide character string literals are supported.
--
-- TEST DESCRIPTION:
-- This test utilizes the brackets scheme for representing wide character
-- values in transportable 7 bit ASCII as proposed by Robert Dewar;
-- this test defines Wide_Character and Wide_String objects, and assigns
-- and tests several sample values.
--
-- SPECIAL REQUIREMENTS:
--
-- This file must be preprocessed before it can be executed as a test.
--
-- This test requires that all occurrences of the bracket escape
-- representation for wide characters be replaced, as appropriate, with
-- the corresponding wide character as represented by the implementation.
--
-- Characters above ASCII.Del are represented by an 8 character sequence:
--
-- ["xxxx"]
--
-- where the character code represented is specified by four hexadecimal
-- digits, (<xxxx>) upper case. For example the wide character with the
-- code 16#ABCD# is represented by the eight character sequence:
--
-- ["ABCD"]
--
-- The following function documents the translation algorithm:
--
-- function To_Wide( S:String ) return Wide_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 Wide_Character'Val(Numerical); -- the returned value is
-- implementation dependent
-- exception
-- when Constraint_Error => raise;
-- end To_Wide;
--
--
-- CHANGE HISTORY:
-- 26 OCT 95 SAIC Initial .Aversion
-- 11 APR 96 SAIC Minor robustness changes for 2.1
-- 12 NOV 96 SAIC Changed file extension to .AW
