| --* |
| -- |
| -- OBJECTIVE: |
| -- Check that the subprograms defined in package Ada.Strings.Wide_Fixed |
| -- are available, and that they produce correct results. Specifically, |
| -- check the subprograms Find_Token, Head, Index, Index_Non_Blank, Move, |
| -- Overwrite, and Replace_Slice, Tail, and Translate. |
| -- Use the access-to-subprogram mapping version of Translate (function |
| -- and procedure). |
| -- |
| -- TEST DESCRIPTION: |
| -- This test demonstrates how certain wide fixed string operations could |
| -- be used in wide 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 wide fixed string processing subprograms are used in this |
| -- test. Each parsing operation attempts to use a different combination |
| -- of the available subprograms to accomplish the same goal, therefore |
| -- continuity of approach to wide 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.Wide_Fixed. |
