|
|
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

|
|
31 -- 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.
