-- Grant of Unlimited Rights
--
-- 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
-- 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
-- OR DISCLOSED, OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A
-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that procedures defined in package Ada.Strings.Unbounded
-- are available, and that they produce correct results. Specifically,
-- check the procedures Replace_Slice, Insert, Overwrite, Delete,
-- Trim (2 versions), Head, and Tail.
--
-- TEST DESCRIPTION:
-- This test demonstrates the uses of many of the procedures defined
-- in package Ada.Strings.Unbounded for use with unbounded strings.
-- The test simulates how unbounded strings could be processed in a
-- user environment, using the procedures provided in this package.
--
-- This test, when taken in conjunction with tests CXA4010, CXA4011,
-- CXA4030, and CXA4031 will constitute a test of all the functionality
-- contained in package Ada.Strings.Unbounded. This test uses a variety
-- of the procedures defined in the unbounded string package in ways
-- typical of common usage.
--
--
-- CHANGE HISTORY:
-- 02 Mar 95 SAIC Initial prerelease version.
