-- OBJECTIVE:
--      Check that the function Ada.Text_IO.Editing.Valid returns False if
--         a) Pic_String is not a well-formed Picture string, or
--         b) the length of Pic_String exceeds Max_Picture_Length, or
--         c) Blank_When_Zero is True and Pic_String contains '*';
--      Check that Valid otherwise returns True.
--
-- TEST DESCRIPTION:
--      This test validates the results of function Editing.Valid under a 
--      variety of conditions.  Both valid and invalid picture strings are
--      provided as input parameters to the function.  The use of the 
--      Blank_When_Zero parameter is evaluated with strings that contain the
--      zero suppression character '*'.
--
-- TEST FILES:
--      The following files comprise this test:

--         FXF3A00.A   (foundation code)
--      => CXF3A01.A
