| --* |
| -- |
| -- OBJECTIVE: |
| -- Check that the operations of Text_IO.Enumeration_IO perform correctly |
| -- on files of Append_File mode, for instantiations using |
| -- enumeration types. Check that Enumeration_IO procedures Put and Get |
| -- properly transfer enumeration data to/from data files. |
| -- Check that the formatting parameters available in the package can |
| -- be used and modified successfully in the storage and retrieval of data. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test is designed to simulate an environment where a data file |
| -- that holds enumeration type information is reset from it current mode |
| -- to allow the appending of data to the end of the This process |
| -- of Reset/Write can be repeated as necessary. All data written |
| -- to the file is verified for accuracy when retrieved from the file. |
| -- |
| -- This test verifies issues of resetting a file created in Out_File mode |
| -- to Append_File mode, resetting from Append_File mode to In_File mode, |
| -- as well as a variety of Text_IO and Enumeration_IO predefined |
| -- subprograms. |
| -- |
| -- APPLICABILITY CRITERIA: |
| -- This test is applicable only to implementations that support text |
| -- files. |
