| -- OBJECTIVE: |
| -- Check that Ada.Strings.Bounded procedures Append, Head, Tail, and |
| -- Trim, and relational operator functions "=", ">", ">=", "<", "<=" |
| -- with parameter combinations of type String and Bounded_String, |
| -- produce correct results. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test examines the operation of several subprograms from within |
| -- the Ada.Strings.Bounded package. Four different instantiations of |
| -- Ada.Strings.Bounded.Generic_Bounded_Length provide packages defined |
| -- to manipulate bounded strings of lengths 1, 20, 40, and 80. |
| -- Examples of the above mentioned procedures and relational operators |
| -- from each of these instantiations are tested, with results compared |
| -- against expected output. |
| -- |
| -- Testing of the function versions of many of the subprograms tested |
| -- here is performed in tests CXA4006-CXA4009. |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 16 Feb 95 SAIC Initial prerelease version |
| -- 10 Mar 95 SAIC Incorporated reviewer comments. |
| -- 15 Apr 96 SAIC Incorporated reviewer comments for ACVC 2.1. |
