--

-- 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.
