26 -- OBJECTIVE:
27 -- Check that the procedures New_Page, Set_Line, Set_Col, and New_Line
28 -- subprograms perform properly on a text file reset (from Out_File)
29 -- with mode Append_File.
30 -- Check that the attributes Page, Line, and Column are all set to 1
31 -- following the reset of a text file with mode Append_File.
32 -- Check that the functions Page, Line, and Col perform properly on a
33 -- text file reset with mode Append_File.
34 -- Check that the procedures Put and Put_Line perform properly on text
35 -- files reset with mode Append_File.
36 -- Check that the procedure Set_Line sets the current line number to
37 -- the value specified by the parameter "To" for text files reset with
38 -- mode Append_File. Check that Set_Line has no effect if the specified
39 -- line equals the current line.
40 -- Check that the procedure Set_Col sets the current column number to
41 -- the value specified by the parameter "To" for text files reset with
42 -- mode Append_File.
43 --
44 -- TEST DESCRIPTION:
45 -- This test is designed to simulate the text processing that could
46 -- occur with files that have been created in Out_File mode,
47 -- and then reset to Append_File mode.
48 -- Various calls to Text_IO formatting subprograms are called to properly
49 -- position text appended to a document. The text content and position
50 -- are subsequently verified for accuracy.
51 --
52 -- APPLICABILITY CRITERIA:
53 -- This test is applicable only to implementations that support text
54 -- files.
55 --
56 --
57 -- CHANGE HISTORY:
58 -- 06 Dec 94 SAIC ACVC 2.0
59 -- 24 Feb 97 PWB.CTA Allowed for non-support of some IO operations.
