| -- OBJECTIVE: |
| -- Check that the types, operations, and other entities defined within |
| -- the package Ada.Strings.Wide_Maps are available and produce correct |
| -- results. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test demonstrates the availability and function of the types and |
| -- operations defined in package Ada.Strings.Wide_Maps. It demonstrates |
| -- the use of these types and functions as they would be used in common |
| -- programming practice. |
| -- Wide_Character set creation, assignment, and comparison are evaluated |
| -- in this test. Each of the functions provided in package |
| -- Ada.Strings.Wide_Maps is utilized in creating or manipulating set |
| -- objects, and the function results are evaluated for correctness. |
| -- Wide_Character sequences are examined using the functions provided for |
| -- manipulating objects of this type. Likewise, Wide_Character maps are |
| -- created, and their contents evaluated. Exception raising conditions |
| -- from the function To_Mapping are also created. |
| -- Note: Throughout this test, the set logical operators are printed in |
| -- capital letters to enhance their visibility. |

| -- 06 Dec 94 SAIC ACVC 2.0 |
| -- 01 Nov 95 SAIC Update and repair for ACVC 2.0.1. |
