| -- OBJECTIVE: |
| -- Check that the subprograms defined in package Ada.Strings.Wide_Bounded |
| -- are available, and that they produce correct results, especially under |
| -- conditions where truncation of the result is required. Specifically, |
| -- check the subprograms Overwrite (function and procedure), Delete, |
| -- Function Trim (blanks), Trim (Set wide characters, function and |
| -- procedure), Head, Tail, and Replicate (wide characters and wide |
| -- strings). |
| -- |
| -- TEST DESCRIPTION: |
| -- This test, in conjunction with tests CXA4017, CXA4018, CXA4019, |
| -- will provide coverage of the most common usages of the functionality |
| -- found in the Ada.Strings.Wide_Bounded package. It deals in large part |
| -- with truncation effects and options. This test contains many small, |
| -- specific test cases, situations that are often difficult to generate |
| -- in large numbers in an application-based test. These cases represent |
| -- specific usage paradigms in-the-small. |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 06 Dec 94 SAIC ACVC 2.0 |
| -- 22 Dec 94 SAIC Changed obsolete constant to Strings.Wide_Space. |
| -- 13 Apr 95 SAIC Corrected certain subtest acceptance conditions. |
