-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
-- 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

-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED

--*
--
-- OBJECTIVE:
-- Check that Ada.Strings.Bounded procedures Append, Head, Tail, and
-- Trim, and relational operator functions "=", ">", ">=", "<", "<="
-- with parameter combinations of type String and Bounded_String,
-- produce correct results.
--
-- TEST DESCRIPTION:
-- This test examines the operation of several subprograms from within
-- the Ada.Strings.Bounded package. Four different instantiations of
-- Ada.Strings.Bounded.Generic_Bounded_Length provide packages defined
-- to manipulate bounded strings of lengths 1, 20, 40, and 80.
-- Examples of the above mentioned procedures and relational operators
-- from each of these instantiations are tested, with results compared
-- against expected output.
--
-- Testing of the function versions of many of the subprograms tested
-- here is performed in tests CXA4006-CXA4009.
--
--
-- CHANGE HISTORY:
-- 16 Feb 95 SAIC Initial prerelease version
-- 10 Mar 95 SAIC Incorporated reviewer comments.
-- 15 Apr 96 SAIC Incorporated reviewer comments for ACVC 2.1.
