-- OBJECTIVE:
|
27 |
|
|
-- Check that Ada.Text_IO.Editing.Put and Ada.Strings.Fixed.Move
|
28 |
|
|
-- have the same effect in putting edited output results into string

|
|
-- TEST DESCRIPTION:
|
32 |
|
|
-- This test is structured using tables of data, consisting of
|
33 |
|
|
-- numerical values, picture strings, and expected image
|
34 |
|
|
-- result strings. These data tables are found in package FXF3A00.
|
35 |
|
|
--
|
36 |
|
|
-- The operation of the two above subprograms are examined twice, first
|
37 |
|
|
-- with the output of an edited output string to a receiving string
|
38 |
|
|
-- object of equal size, the other to a receiving string object of
|
39 |
|
|
-- larger size, where justification and padding are considered.
|
40 |
|
|
-- The procedure Editing.Put will place an edited output string into
|
41 |
|
|
-- a larger receiving string with right justification and blank fill.
|
42 |
|
|
-- Procedure Move has parameter control of justification and fill, and
|
43 |
|
|
-- in this test will mirror Put by specifying right justification and
|
44 |
|
|
-- blank fill.
|
45 |
|
|
--
|
46 |
|
|
-- In the cases where the edited output string is of shorter length
|
47 |
|
|
-- than the receiving string object, a blank-filled constant string
|
48 |
|
|
-- will be catenated to the front of the expected edited output string
|
49 |
|
|
-- for comparison with the receiving string object, enabling direct
|
50 |
|
|
-- string comparison for result verification.
