26
-- OBJECTIVE:
27
--      Check that the subprograms defined in package Ada.Strings.Fixed are
28
--      available, and that they produce correct results.  Specifically,
29
--      check the subprograms Index, "*" (string constructor function),
30
--      Count, Trim, and Replace_Slice.
31
--
32
-- TEST DESCRIPTION:
33
--      This test demonstrates how certain Fixed string functions are used
34
--      to eliminate specific substrings from portions of text.  A procedure
35
--      is defined that will take as parameters a source string along with
36
--      a substring that is to be completely removed from the source string.
37
--      The source string is parsed using the Index function, and any substring
38
--      slices are replaced in the source string by a series of X's (based on
39
--      the length of the substring.)
40
--      Three lines of text are provided to this procedure, and the resulting
41
--      substitutions are compared with expected results to validate the
42
--      string processing.
43
--      A global accumulator is updated with the number of occurrences of the
44
--      substring in the source string.
