Release History for pForth - a Portable ANS-like Forth written in ANSI 'C'

Documentation for pForth at http://www.softsynth.com/pforth/

V28 - unreleased
    - fixes for MinGW build

V27 - 11/22/2010
    - Fixed REPOSITION-FILE FILE-SIZE and FILE-POSITION.
      They used to use single precision offset. Now use double as specified.
    - Delete object directories in Makefile clean.
    - Fixed "Issue 4: Filehandle remains locked upon INCLUDE error".
      http://code.google.com/p/pforth/issues/detail?id=4&can=1
    - Fixed scrambled HISTORY on 64-bit systems. Was using CELL+ but really needed 4 +.
    - Fixed floating point input. Now accepts "1E" as 1.0. Was Issue #2.
    - Fixed lots of warning and made code compatible with C89 and ANSI. Uses -pedantic.
    - Use fseek and ftell on WIN32 instead of fseeko and ftello.
    - Makefile is now more standard. Builds in same dir as Makefile. Uses CFLAGS etc.
    - Add support for console IO with _WATCOMC_
    - Internal CStringToForth and ForthStringToC now take a destination size for safety.
    - Run units tests for CStringToForth and ForthStringToC if PF_UNIT_TESTS is defined.

V26  5/20/2010
    - 64-bit support for M* UM/MOD etc by Aleksej Saushev. Thanks Aleksej!
    
V25  5/19/2010
    - Added 64-bit CELL support contributed by Aleksej Saushev. Thanks Aleksej!
    - Added "-x c" to Makefile CCOPTS to prevent confusion with C++
    - Allow space after -d command line option.
    - Restore normal tty mode if pForth dictionary loading fails.
     
V24 2/20/09
    - Fixed Posix IO on Mac. ?TERMINAL was always returning true.
    - ACCCEPT now emits a space at end of line before output.
    - Fixed RESIZE because it was returning the wrong address.

V23 8/4/2008
    - Removed -v option from mkdir in build/unix/Makefile. It was not supported on FreeBSD.
      Thank you Alexsej Saushev for reporting this.
    
V23  7/20/2008
    - Reorganized for Google Code project.
    
V22  (unreleased)
    - Added command line history and cursor control words.
    - Sped up UM* and M* by a factor of 3. Thanks to Steve Green for suggested algorithm.
    - Modified ACCEPT so that a line at the end of a file that does NOT have a line
        terminator will now be processed.
    - Use _getch(), _putch(), and _kbhit() so that KEY, EMIT and ?TERMINAL will work on PC.
    - Fixed  : foo { -- } 55 ;  - Was entering local frame but not exiting. Now prints error.
    - Redefined MAKE_ID to protect it from 16 bit ints
    - John Providenza says "If you split local variables onto 2 lines, PForth crashes." Fixed. Also allow \
    - Fixed float evaluation in EVALUATE in "quit.fth".
    - Flush register cache for ffColon and ffSemiColon to prevent stack warnings from ;

V21 - 9/16/1998
    - Fixed some compiler warnings.

V20
    - Expand PAD for ConvertNumberToText so "-1 binary .s" doesn't crash.
      Thank you Michael Connor of Vancouver for reporting this bug.

    - Removed FDROP in REPRESENT to fix stack underflow after "0.0 F.".
      Thank you Jim Rosenow of Minnesota for reporting this bug.
    - Changed pfCharToLower to function to prevent macro expansion bugs under VXWORKS
      Thank you Jim Rosenow of Minnesota for reporting this bug.

    - "0.0 F~" now checks actual binary encoding of floats. Before this it used to just
      compare value which was incorrect. Now "0.0 -0.0 0.0 F~" returns FALSE.

    - Fixed definition of INPUT$ in tutorial.
      Thank you Hampton Miller of California for reporting this bug.

    - Added support for producing a target dictionary with a different
      Endian-ness than the host CPU.  See PF_BIG_ENDIAN_DIC and PF_LITTLE_ENDIAN_DIC.

    - PForth kernel now comes up in a mode that uses BASE for numeric input when
      started with "-i" option.  It used to always consider numeric input as HEX.
      Initial BASE is decimal.  

V19  4/1998

    - Warn if local var name matches dictionary, : foo { count -- } ;
    - TO -> and +-> now parse input stream. No longer use to-flag.
    - TO -> and +-> now give error if used with non-immediate word.
    - Added (FLITERAL) support to SEE.
    - Aded TRACE facility for single step debugging of Forth words.
    - Added stub for ?TERMINAL and KEY? for embedded systems.
    - Added PF_NO_GLOBAL_INIT for no reliance on global initialization.
    - Added PF_USER_FLOAT for customization of FP support.
    - Added floating point to string conversion words (F.) (FS.) (FE.)
        For example:   : F.   (F.)  TYPE  SPACE  ;
    - Reversed order that values are placed on return stack in 2>R
      so that it matches ANS standard.  2>R is now same as SWAP >R >R
      Thank you Leo Wong for reporting this bug.

    - Added PF_USER_INIT and PF_USER_TERM for user definable init and term calls.

    - FIXED memory leak in pfDoForth()

V18
    - Make FILL a 'C' primitive.
    - optimized locals with (1_LOCAL@)
    - optimized inner interpreter by 15%
    - fix tester.fth failures
    - Added define for PF_KEY_ECHOS which turns off echo in ACCEPT if defined.
    - Fixed MARKER. Was equivalent to ANEW instead of proper ANS definition.
    - Fixed saving and restoring of TIB when nesting include files.

V17
    - Fixed input of large floats.  0.7071234567 F.  used to fail.

V16
    * Define PF_USER_CUSTOM if you are defining your own custom
      'C' glue routines.  This will ifndef the published example.
    - Fixed warning in pf_cglue.c.
    - Fixed SDAD in savedicd.fth.  It used to generate bogus 'C' code
      if called when (BASE != 10), as in HEX mode.
    - Fixed address comparisons in forget.fth and private.fth for
      addresses above 0x80000000. Must be unsigned.
    - Call FREEZE at end of system.fth to initialize rfence.
    - Fixed 0.0 F. which used to leave 0.0 on FP stack.
    - Added FPICK ( n -- ) ( i*f -- i*f f[n] )
    - .S now prints hex numbers as unsigned.
    - Fixed internal number to text conversion for unsigned nums.

V15 - 2/15/97
    * If you use PF_USER_FILEIO, you must now define PF_STDIN and PF_STDOUT
      among other additions. See "pf_io.h".
    * COMPARE now matches ANS STRING word set!
    - Added PF_USER_INC1 and PF_USER_INC2 for optional includes
      and host customization. See "pf_all.h".
    - Fixed more warnings.
    - Fixed >NAME and WORDS for systems with high "negative" addresses.
    - Added WORDS.LIKE utility.  Enter:   WORDS.LIKE EMIT
    - Added stack check after every word in high level interpreter.
      Enter QUIT to enter high level interpreter which uses this feature.
    - THROW will no longer crash if not using high level interpreter.
    - Isolated all host dependencies into "pf_unix.h", "pf_win32.h",
      "pf_mac.h", etc.  See "pf_all.h".
    - Added tests for CORE EXT, STRINGS words sets.
    - Added SEARCH
    - Fixed WHILE and REPEAT for multiple WHILEs.
    - Fixed .( ) for empty strings.
    - Fixed FATAN2 which could not compile on some systems (Linux gcc).

V14 - 12/23/96
    * pforth command now requires -d before dictionary name.
            Eg.   pforth -dcustom.dic test.fth
    * PF_USER_* now need to be defined as include file names.
    * PF_USER_CHARIO now requires different functions to be defined.
        See "csrc/pf_io.h".

      file with main().

V13 - 12/15/96
    - Add "extern 'C' {" to pf_mem.h for C++
    - Separate PF_STATIC_DIC from PF_NO_FILEIO so that we can use a static
      dictionary but also have file I/O.
    - Added PF_USER_FILEIO, PF_USER_CHARIO, PF_USER_CLIB.
    - INCLUDE now aborts if file not found.
    - Add +-> which allows you to add to a local variable, like +! .
    - VALUE now works properly as a self fetching constant.
    - Add CODE-SIZE and HEADERS-SIZE which lets you resize
      dictionary saved using SAVE-FORTH.
    - Added FILE?. Enter "FILE? THEN" to see what files THEN is defined in.
    - Fixed bug in local variables that caused problems if compilation
      aborted in a word with local variables.
    - Added SEE which "disassembles" Forth words. See "see.fth".
    - Added PRIVATE{ which can be used to hide low level support
      words.  See "private.fth".
    
V12 - 12/1/96
    - Advance pointers in pfCopyMemory() and pfSetMemory()
      to fix PF_NO_CLIB build.
    - Increase size of array for PF_NO_MALLOC

    - Conditionally eliminate some include files for embedded builds.
    - Cleanup some test files.

V11 - 11/14/96

    - Changed DO LOOP to ?DO LOOP in ENDCASE and LV.MATCH
      to fix hang when zero local variables.

    - Add PF_HOST_DOS for compilation control.
    - Shorten all long file names to fit in the 8.3 format
      required by some primitive operating systems. My
      apologies to those with modern computers who suffer
      as a result.  ;-)
    
V9 - 10/13/95
