|
|
26 -- OBJECTIVE:
|
|
|
27 -- Check that the function Ada.Text_IO.Editing.Valid returns False if
|
|
|
28 -- a) Pic_String is not a well-formed Picture string, or
|
|
|
29 -- b) the length of Pic_String exceeds Max_Picture_Length, or
|
|
|
30 -- c) Blank_When_Zero is True and Pic_String contains '*';
|
|
|
31 -- Check that Valid otherwise returns True.
|
|
|
32 --
|
|
|
33 -- TEST DESCRIPTION:
|
|
|
34 -- This test validates the results of function Editing.Valid under a
|
|
|
35 -- variety of conditions. Both valid and invalid picture strings are
|
|
|
36 -- provided as input parameters to the function. The use of the
|
|
|
37 -- Blank_When_Zero parameter is evaluated with strings that contain the
|
|
|
38 -- zero suppression character '*'.
