| -- OBJECTIVE: |
| -- Check that the subprograms defined in package Ada.Strings.Fixed are |
| -- available, and that they produce correct results. Specifically, check |
| -- the subprograms Count, Find_Token, Index, Index_Non_Blank, and Move. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test, when combined with tests CXA4002,3, and 5 will provide |
| -- thorough coverage of the functionality found in Ada.Strings.Fixed. |
| -- This test contains many small, specific test cases, situations that |
| -- although common in user environments, are often difficult to generate |
| -- in large numbers in a application-based test. |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 06 Dec 94 SAIC ACVC 2.0 |
| -- 10 Apr 95 SAIC Corrected subtest for Move, Drop=Right. |
