| -- OBJECTIVE: |
| -- Check that the procedures New_Page, Set_Line, Set_Col, and New_Line |
| -- subprograms perform properly on a text file created with mode |
| -- Append_File. |
| -- Check that the attributes Page, Line, and Column are all set to 1 |
| -- following the creation of a text file with mode Append_File. |
| -- Check that the functions Page, Line, and Col perform properly on a |
| -- text file created with mode Append_File. |
| -- Check that the procedures Put and Put_Line perform properly on text |
| -- files created with mode Append_File. |
| -- Check that the procedure Set_Line sets the current line number to |
| -- the value specified by the parameter "To" for text files created with |
| -- mode Append_File. |
| -- Check that the procedure Set_Col sets the current column number to |
| -- the value specified by the parameter "To" for text files created with |
| -- mode Append_File. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test is designed to simulate the text processing that could |
| -- occur with files that have been created in Append_File mode. Various |
| -- calls to Text_IO formatting subprograms are called to properly |
| -- position text appended to a document. The text content and position |
| -- are subsequently verified for accuracy. |
| -- |
| -- APPLICABILITY CRITERIA: |
| -- This test is applicable only to implementations that support text |
| -- files. |
