-- OBJECTIVE:
--      Check that the character classification functions defined in 
--      package Ada.Characters.Handling produce correct results when provided 
--      constant arguments from package Ada.Characters.Latin_1.
--
-- TEST DESCRIPTION:
--      This test checks the character classification functions of package
--      Ada.Characters.Handling.  In the evaluation of each function, loops
--      are constructed to examine the function with as many values of type
--      Character (Ada.Characters.Latin_1 constants) as possible in an 
--      amount of code that is about equal to the amount of code required
--      to examine the function with a few representative input values and
--      endpoint values.
--      The usage paradigm being demonstrated by this test is that of the
--      functions being used to assign to boolean variables, as well as
--      serving as boolean conditions.
--      
--       
-- CHANGE HISTORY:
--      06 Dec 94   SAIC    ACVC 2.0
--      29 Apr 95   SAIC    Fixed subtest checking Is_Graphic function.
