| --* |
| -- |
| -- OBJECTIVE: |
| -- Check that the capabilities provided in instantiations of the |
| -- Ada.Text_IO.Fixed_IO package operate correctly when the mode of |
| -- the file is Append_File. Check that Fixed_IO procedures Put and Get |
| -- properly transfer fixed point data to/from data files that are in |
| -- Append_File mode. Check that the formatting parameters available in |
| -- the package can be used and modified successfully in the appending and |
| -- retrieval of data. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test simulates order processing, with data values being written |
| -- to a file, in a specific format, using Fixed_IO. Validation is done |
| -- on this process by reading the data values from the file, and |
| -- comparing them for equality with the values originally written to |
| -- the file. |
| -- |
| -- This test verifies issues of create in Append_File mode, appending to |
| -- a file previously appended to, resetting to Append_File mode, |
| -- resetting from Append_File mode to In_File mode, as well as a |
| -- variety of Text_IO and Fixed_IO predefined subprograms. |
| -- |
| -- APPLICABILITY CRITERIA: |
| -- This test is applicable only to implementations that support text |
| -- files. |
