--*
--
-- 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

-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
