- - fix $ROM
- - fix HISTORY
- - 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".
- - Moved pfDoForth() from pf_main.c to pf_core.c to simplify
- file with main().
- - Fix build with PF_NO_INIT
- - Makefile now has target for embedded dictionary, "gmake pfemb".
-
-V13 - 12/15/96

- - INCLUDE now aborts if file not found.
- - Add +-> which allows you to add to a local variable, like +! .

- 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

- to fix PF_NO_CLIB build.
- - Increase size of array for PF_NO_MALLOC

- apologies to those with modern computers who suffer
- as a result. ;-)
