26 -- OBJECTIVE:
27 -- Check that the function Ada.Text_IO.Editing.To_Picture raises
28 -- Picture_Error if the picture string provided as input parameter does
29 -- not conform to the composition constraints defined for picture
30 -- strings.
31 -- Check that when Pic_String is applied to To_Picture, the result
32 -- is equivalent to the actual string parameter of To_Picture;
33 -- Check that when Blank_When_Zero is applied to To_Picture, the result
34 -- is the same value as the Blank_When_Zero parameter of To_Picture.
35 --
36 -- TEST DESCRIPTION:
37 -- This test validates that function Editing.To_Picture returns a
38 -- Picture result when provided a valid picture string, and raises a
39 -- Picture_Error exception when provided an invalid picture string
40 -- input parameter. In addition, the Picture result of To_Picture is
41 -- converted back to a picture string value using function Pic_String,
42 -- and the result of function Blank_When_Zero is validated based on the
43 -- value of parameter Blank_When_Zero used in the formation of the Picture
44 -- by function To_Picture.
