15 \ ----------------------------------------------------------------------------
16 \ Version 0.13 S" in interpretation mode tested.
17 \ Added SAVE-INPUT RESTORE-INPUT REFILL in a file, (moved from
19 \ Calls to COMPARE replaced with S= (in utilities.fth)
20 \ 0.11 25 April 2015 S\" in interpretation mode test added
21 \ REQUIRED REQUIRE INCLUDE tests added
22 \ Two S" and/or S\" buffers availability tested
23 \ 0.5 1 April 2012 Tests placed in the public domain.
24 \ 0.4 22 March 2009 { and } replaced with T{ and }T
25 \ 0.3 20 April 2007 ANS Forth words changed to upper case.
26 \ Removed directory test from the filenames.
27 \ 0.2 30 Oct 2006 updated following GForth tests to remove
28 \ system dependency on file size, to allow for file
29 \ buffering and to allow for PAD moving around.
30 \ 0.1 Oct 2006 First version released.
32 \ ----------------------------------------------------------------------------
33 \ The tests are based on John Hayes test program for the core word set
34 \ and requires those files to have been loaded
36 \ Words tested in this file are:
37 \ ( BIN CLOSE-FILE CREATE-FILE DELETE-FILE FILE-POSITION FILE-SIZE
38 \ OPEN-FILE R/O R/W READ-FILE READ-LINE REPOSITION-FILE RESIZE-FILE
39 \ S" S\" SOURCE-ID W/O WRITE-FILE WRITE-LINE
40 \ FILE-STATUS FLUSH-FILE RENAME-FILE SAVE-INPUT RESTORE-INPUT
44 \ INCLUDED INCLUDE-FILE (as these will likely have been
45 \ tested in the execution of the test files)
46 \ ----------------------------------------------------------------------------
47 \ Assumptions, dependencies and notes:
48 \ - tester.fr (or ttester.fs), errorreport.fth and utilities.fth have been
49 \ included prior to this file
50 \ - the Core word set is available and tested
51 \ - These tests create files in the current directory, if all goes
52 \ well these will be deleted. If something fails they may not be
53 \ deleted. If this is a problem ensure you set a suitable
54 \ directory before running this test. There is no ANS standard
55 \ way of doing this. Also be aware of the file names used below
56 \ which are: fatest1.txt, fatest2.txt and fatest3.txt
