| -- OBJECTIVE: |
| -- Check that the subprograms defined in package Ada.Strings.Fixed are |
| -- available, and that they produce correct results. Specifically, |
| -- check the subprograms Index, Index_Non_Blank, Head, Tail, Translate, |
| -- Find_Token, Move, Overwrite, and Replace_Slice. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test demonstrates how certain fixed string operations could be |
| -- used in string information processing. A procedure is defined that |
| -- will extract portions of a 50 character string that correspond to |
| -- certain data items (i.e., name, address, state, zip code). These |
| -- parsed items will then be added to the appropriate fields of data |
| -- base elements. These data base elements are then compared for |
| -- accuracy against a similar set of predefined data base elements. |
| -- |
| -- A variety of fixed string processing subprograms are used in this |
| -- test. Each parsing operation uses a different combination |
| -- of the available subprograms to accomplish the same goal, therefore |
| -- continuity of approach to string parsing is not seen in this test. |
| -- However, a wide variety of possible approaches are demonstrated, while |
| -- exercising a large number of the total predefined subprograms of |
| -- package Ada.Strings.Fixed. |
