-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained
-- unlimited rights in the software and documentation contained herein.
-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
-- this public release, the Government intends to confer upon all
-- recipients unlimited rights equal to those held by the Government.
-- These rights include rights to use, duplicate, release or disclose the
-- released technical data and computer software in whole or in part, in
-- any manner and for any purpose whatsoever, and to have or permit others
-- to do so.
--
-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED
-- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE
-- SOFTWARE, DOCUMENTATION OR OTHER INFORMATION RELEASED, MADE AVAILABLE

-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that the subprograms defined in package
-- Ada.Strings.Wide_Bounded are available, and that they produce
-- correct results. Specifically, check the subprograms Append,
-- Count, Element, Find_Token, Head, Index_Non_Blank, Replace_Element,
-- Replicate, Tail, To_Bounded_Wide_String, "&", ">", "<", ">=", "<=",
-- and "*".
--
-- TEST DESCRIPTION:
-- This test, when taken in conjunction with test CXA40[17,19,20], will
-- constitute a test of all the functionality contained in package
-- Ada.Strings.Wide_Bounded. This test uses a variety of the
-- subprograms defined in the wide bounded string package in ways typical
-- of common usage. Different combinations of available subprograms
-- are used to accomplish similar wide bounded string processing goals.
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
-- 22 Dec 94 SAIC Changed obsolete constant to Strings.Wide_Space.
-- 06 Nov 95 SAIC Corrected evaluation string used in Head/Tail
-- subtests for ACVC 2.0.1.
