--

-- 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
