| -- OBJECTIVE: |
| -- Check that the operations defined in package Wide_Text_IO allow for |
| -- the input/output of Wide_Character and Wide_String data. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test is designed to exercise the components of the Wide_Text_IO |
| -- package, including the Put/Get utilities for Wide_Characters and |
| -- Wide_String objects. |
| -- The test utilizes the Put and Get procedures defined for |
| -- Wide_Characters, as well as the Put, Get, Put_Line, and Get_Line |
| -- procedures defined for Wide_Strings. In addition, many of the |
| -- additional subprograms found in package Wide_Text_IO are used in this |
| -- test. |
| -- |
| -- APPLICABILITY CRITERIA: |
| -- This test is applicable to all implementations capable of supporting |
| -- external Wide_Text_IO files. |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 06 Dec 94 SAIC ACVC 2.0 |
| -- 26 Feb 97 CTA.PWB Allowed for non-support of some IO operations. |
