--
-- OBJECTIVE:
-- Check that the subprograms defined in package Ada.Strings.Bounded are
-- available, and that they produce correct results, especially under
-- conditions where truncation of the result is required. Specifically,
-- check the subprograms Append, Count with non-Identity maps, Index with
-- non-Identity maps, Index with Set parameters, Insert (function and
-- procedure), Replace_Slice (function and procedure), To_Bounded_String,
-- and Translate.
--
-- TEST DESCRIPTION:
-- This test, in conjunction with tests CXA4006, CXA4007, and CXA4009,
-- will provide coverage of the most common usages of the functionality
-- found in the Ada.Strings.Bounded package. It deals in large part
-- with truncation effects and options. This test contains many small,
-- specific test cases, situations that are often difficult to generate
-- in large numbers in an application-based test. These cases represent
-- specific usage paradigms in-the-small.
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
-- 10 Apr 95 SAIC Corrected acceptance condition of subtest for
-- Function Append with Truncation = Left.
-- 31 Oct 95 SAIC Update and repair for ACVC 2.0.1.
