| -- OBJECTIVE: |
| -- Check that Ada.Text_IO.Editing.Put and Ada.Text_IO.Put have the same |
| -- effect. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test is structured using tables of data, consisting of |
| -- numerical values, picture strings, and expected image |
| -- result strings. These data tables are found in package FXF3A00. |
| -- |
| -- The testing approach used in this test is that of writing edited |
| -- output data to a text file, using two different approaches. First, |
| -- Ada.Text_IO.Put is used, with a call to an instantiated version of |
| -- Function Image supplied as the actual for parameter Item. The |
| -- second approach is to use a version of Function Put from an |
| -- instantiation of Ada.Text_IO.Editing.Decimal_Output, with the |
| -- appropriate parameters for decimal data, picture, and format |
| -- specific parameters. A call to New_Line follows each Put, so that |
| -- each entry is placed on a separate line in the text file. |
| -- |
| -- Edited output for decimal data with two decimal places is in the |
| -- first loop, and once the data has been written to the file, the |
| -- text file is closed, then opened in In_File mode. The edited |
| -- output data is read from the file, and data on successive lines |
| -- is compared with the expected edited output result. The edited |
| -- output data produced by both of the Put procedures should be |
| -- identical. |
| -- |
| -- This process is repeated for decimal data with no decimal places. |
| -- The file is reopened in Append_File mode, and the edited output |
| -- data is added to the file in the same manner as described above. |
| -- The file is closed, and reopened to verify the data written. |
| -- The data written above (with two decimal places) is skipped, then |
| -- the data to be verified is extracted as above and verified against |
| -- the expected edited output string values. |
| -- |
| -- APPLICABILITY CRITERIA: |
| -- This test is applicable only to implementations that support |
| -- external text files. |
| -- |
| -- TEST FILES: |
| -- The following files comprise this test: |

| -- CHANGE HISTORY: |
| -- 26 JAN 95 SAIC Initial prerelease version. |
| -- 26 FEB 97 PWB.CTA Made input buffers sufficiently long |
| -- and removed code depending on shorter buffers |
