| -- |
| -- OBJECTIVE: |
| -- Check that the subprograms defined in package Ada.Strings.Unbounded |
| -- are available, and that they produce correct results. Specifically, |
| -- check the functions To_Unbounded_String (version with Length |
| -- parameter), "=", "<", "<=", ">", ">=" (all with String-Unbounded |
| -- String parameter mix), as well as three versions of Procedure Append. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test demonstrates the uses of many of the subprograms defined |
| -- in package Ada.Strings.Unbounded for use with unbounded strings. |
| -- The test simulates how unbounded strings could be processed in a |
| -- user environment, using the subprograms provided in this package. |
| -- |
| -- This test, when taken in conjunction with tests CXA4010, CXA4011, |
| -- CXA4030, and CXA4032 will constitute a test of all the functionality |
| -- contained in package Ada.Strings.Unbounded. This test uses a variety |
| -- of the subprograms defined in the unbounded string package in ways |
| -- typical of common usage. |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 27 Feb 95 SAIC Initial prerelease version. |
| -- 18 Apr 96 SAIC Incorporated reviewer comments for ACVC 2.1. |
