\ ------------------------------------------------------------------------------
\ Version 0.13 28 October 2015
\ Replace <FALSE> and <TRUE> with FALSE and TRUE to avoid
\ dependence on Core tests
\ Moved SAVE-INPUT and RESTORE-INPUT tests in a file to filetest.fth
\ Use of 2VARIABLE (from optional wordset) replaced with CREATE.
\ Minor lower to upper case conversions.
\ Calls to COMPARE replaced by S= (in utilities.fth) to avoid use
\ of a word from an optional word set.
\ UNUSED tests revised as UNUSED UNUSED = may return FALSE when an
\ implementation has the data stack sharing unused dataspace.
\ Double number input dependency removed from the HOLDS tests.
\ Minor case sensitivities removed in definition names.
\ 0.11 25 April 2015
\ Added tests for PARSE-NAME HOLDS BUFFER:
\ S\" tests added
\ DEFER IS ACTION-OF DEFER! DEFER@ tests added
\ Empty CASE statement test added
\ [COMPILE] tests removed because it is obsolescent in Forth 2012
\ 0.10 1 August 2014
\ Added tests contributed by James Bowman for:
\ <> U> 0<> 0> NIP TUCK ROLL PICK 2>R 2R@ 2R>
\ HEX WITHIN UNUSED AGAIN MARKER
\ Added tests for:
\ .R U.R ERASE PAD REFILL SOURCE-ID
\ Removed ABORT from NeverExecuted to enable Win32
\ to continue after failure of RESTORE-INPUT.
\ Removed max-intx which is no longer used.
\ 0.7 6 June 2012 Extra CASE test added
\ 0.6 1 April 2012 Tests placed in the public domain.
\ SAVE-INPUT & RESTORE-INPUT tests, position
\ of T{ moved so that tests work with ttester.fs
\ CONVERT test deleted - obsolete word removed from Forth 200X
\ IMMEDIATE VALUEs tested
\ RECURSE with :NONAME tested
\ PARSE and .( tested
\ Parsing behaviour of C" added
\ 0.5 14 September 2011 Removed the double [ELSE] from the
\ initial SAVE-INPUT & RESTORE-INPUT test
\ 0.4 30 November 2009 max-int replaced with max-intx to
\ avoid redefinition warnings.
\ 0.3 6 March 2009 { and } replaced with T{ and }T
\ CONVERT test now independent of cell size
\ 0.2 20 April 2007 ANS Forth words changed to upper case
\ Tests qd3 to qd6 by Reinhold Straub
\ 0.1 Oct 2006 First version released
\ -----------------------------------------------------------------------------
\ The tests are based on John Hayes test program for the core word set
\ Words tested in this file are:
\ .( .R 0<> 0> 2>R 2R> 2R@ :NONAME <> ?DO AGAIN C" CASE COMPILE, ENDCASE
\ ENDOF ERASE FALSE HEX MARKER NIP OF PAD PARSE PICK REFILL
\ RESTORE-INPUT ROLL SAVE-INPUT SOURCE-ID TO TRUE TUCK U.R U> UNUSED
\ VALUE WITHIN [COMPILE]
\ Words not tested or partially tested:
\ \ because it has been extensively used already and is, hence, unnecessary
\ REFILL and SOURCE-ID from the user input device which are not possible
\ when testing from a file such as this one
\ UNUSED (partially tested) as the value returned is system dependent
\ Obsolescent words #TIB CONVERT EXPECT QUERY SPAN TIB as they have been
\ removed from the Forth 2012 standard
\ Results from words that output to the user output device have to visually
\ checked for correctness. These are .R U.R .(
\ -----------------------------------------------------------------------------
\ Assumptions & dependencies:
\ - tester.fr (or ttester.fs), errorreport.fth and utilities.fth have been
\ included prior to this file
\ - the Core word set available
