-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED
-- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE
-- SOFTWARE, DOCUMENTATION OR OTHER INFORMATION RELEASED, MADE AVAILABLE
-- OR DISCLOSED, OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A
-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that the function Ada.Text_IO.Editing.To_Picture raises
-- Picture_Error if the picture string provided as input parameter does
-- not conform to the composition constraints defined for picture
-- strings.
-- Check that when Pic_String is applied to To_Picture, the result
-- is equivalent to the actual string parameter of To_Picture;
-- Check that when Blank_When_Zero is applied to To_Picture, the result
-- is the same value as the Blank_When_Zero parameter of To_Picture.
--
-- TEST DESCRIPTION:
-- This test validates that function Editing.To_Picture returns a
-- Picture result when provided a valid picture string, and raises a
-- Picture_Error exception when provided an invalid picture string
-- input parameter. In addition, the Picture result of To_Picture is
-- converted back to a picture string value using function Pic_String,
-- and the result of function Blank_When_Zero is validated based on the
-- value of parameter Blank_When_Zero used in the formation of the Picture
-- by function To_Picture.
--
-- TEST FILES:
-- The following files comprise this test:
--
-- FXF3A00.A (foundation code)
-- => CXF3A02.A
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
-- 11 Mar 97 PWB.CTA Corrected invalid picture string and uppercase
-- problem.
--!
