HE		 1\ Test PForth FILE wordset

13\ The tests are not claimed to be comprehensive or correct
14
15\ ----------------------------------------------------------------------------
16\ Version 0.13 S" in interpretation mode tested.
17\ Added SAVE-INPUT RESTORE-INPUT REFILL in a file, (moved from
18\ coreexttest.fth).
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.
31
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
35
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
41\ REFILL
42
43\ Words not tested:
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
