26
-- OBJECTIVE:
27
--      Check that the functionality found in packages Ada.Strings.Wide_Maps,
28
--      Ada.Strings.Wide_Fixed, and Ada.Strings.Wide_Maps.Wide_Constants
29
--      is available and produces correct results.
30
--
31
-- TEST DESCRIPTION:
32
--      This test validates the subprograms found in the various Wide_Map
33
--      and Wide_String packages.  It is based on the tests CXA4024 and
34
--      CXA4026, which are tests for the complementary "non-wide" packages.
35
--
36
--      The functions found in CXA4025_0 provide mapping capability, when
37
--      used in conjunction with Wide_Character_Mapping_Function objects.
38

39
--
40
-- CHANGE HISTORY:
41
--      23 Jun 95   SAIC    Initial prerelease version.
42
--      15 Apr 96   SAIC    Incorporated reviewer comments for ACVC 2.1.
