--

-- OBJECTIVE:

--      Check that the functionality found in packages Ada.Strings.Wide_Maps,

--      Ada.Strings.Wide_Bounded, and Ada.Strings.Wide_Maps.Wide_Constants

--      is available and produces correct results.

--

-- TEST DESCRIPTION:

--      This test tests the subprograms found in the

--      Ada.Strings.Wide_Bounded package.  It is based on the tests

--      CXA4027-28, which are tests for the complementary "non-wide"

--      packages.

--

--      The functions found in CXA4029_0 provide mapping capability, when

--      used in conjunction with Wide_Character_Mapping_Function objects.

--

--

-- CHANGE HISTORY:

--      23 Jun 95   SAIC    Initial prerelease version.

--      18 Apr 96   SAIC    Incorporated reviewer comments for ACVC 2.1.
