\r
Documentation for pForth at http://www.softsynth.com/pforth/\r
\r
V?? \r
	- Allow space after -d command line option.\r
	- Restore normal tty mode if pForth dictionary loading fails.\r
	 \r
V24 2/20/09\r
	- Fixed Posix IO on Mac. ?TERMINAL was always returning true.\r
	- ACCCEPT now emits a space at end of line before output.\r
	- Fixed RESIZE because it was returning the wrong address.\r
\r
V23 8/4/2008\r
	- Removed -v option from mkdir in build/unix/Makefile. It was not supported on FreeBSD.\r
	  Thank you Alexsej Saushev for reporting this.\r
	\r
V23  7/20/2008\r
    - Reorganized for Google Code project.\r
    \r
V22  (unreleased)\r
    - Added command line history and cursor control words.\r
	- Sped up UM* and M* by a factor of 3. Thanks to Steve Green for suggested algorithm.\r
	- Modified ACCEPT so that a line at the end of a file that does NOT have a line\r
	    terminator will now be processed.\r
	- Use _getch(), _putch(), and _kbhit() so that KEY, EMIT and ?TERMINAL will work on PC.\r
	- Fixed  : foo { -- } 55 ;  - Was entering local frame but not exiting. Now prints error.\r
    - Redefined MAKE_ID to protect it from 16 bit ints\r
    - John Providenza says "If you split local variables onto 2 lines, PForth crashes." Fixed. Also allow \\r
    - Fixed float evaluation in EVALUATE in "quit.fth".\r
    - Flush register cache for ffColon and ffSemiColon to prevent stack warnings from ;\r
\r
V21 - 9/16/98\r
	- Fixed some compiler warnings.\r
\r
V20\r
    - Expand PAD for ConvertNumberToText so "-1 binary .s" doesn't crash.\r
      Thank you Michael Connor of Vancouver for reporting this bug.\r
\r
    - Removed FDROP in REPRESENT to fix stack underflow after "0.0 F.".\r
      Thank you Jim Rosenow of Minnesota for reporting this bug.\r
	- Changed pfCharToLower to function to prevent macro expansion bugs under VXWORKS\r
      Thank you Jim Rosenow of Minnesota for reporting this bug.\r
\r
	- "0.0 F~" now checks actual binary encoding of floats. Before this it used to just\r
	  compare value which was incorrect. Now "0.0 -0.0 0.0 F~" returns FALSE.\r
\r
	- Fixed definition of INPUT$ in tutorial.\r
      Thank you Hampton Miller of California for reporting this bug.\r
\r
	- Added support for producing a target dictionary with a different\r
	  Endian-ness than the host CPU.  See PF_BIG_ENDIAN_DIC and PF_LITTLE_ENDIAN_DIC.\r
\r
	- PForth kernel now comes up in a mode that uses BASE for numeric input when\r
	  started with "-i" option.  It used to always consider numeric input as HEX.\r
	  Initial BASE is decimal.  \r
\r
V19  4/98\r
\r
	- Warn if local var name matches dictionary, : foo { count -- } ;\r
	- TO -> and +-> now parse input stream. No longer use to-flag.\r
	- TO -> and +-> now give error if used with non-immediate word.\r
	- Added (FLITERAL) support to SEE.\r
	- Aded TRACE facility for single step debugging of Forth words.\r
	- Added stub for ?TERMINAL and KEY? for embedded systems.\r
	- Added PF_NO_GLOBAL_INIT for no reliance on global initialization.\r
	- Added PF_USER_FLOAT for customization of FP support.\r
	- Added floating point to string conversion words (F.) (FS.) (FE.)\r
	    For example:   : F.   (F.)  TYPE  SPACE  ;\r
	- Reversed order that values are placed on return stack in 2>R\r
	  so that it matches ANS standard.  2>R is now same as SWAP >R >R\r
	  Thank you Leo Wong for reporting this bug.\r
\r
	- Added PF_USER_INIT and PF_USER_TERM for user definable init and term calls.\r
\r
	- FIXED memory leak in pfDoForth()\r
\r
V18\r
	- Make FILL a 'C' primitive.\r
	- optimized locals with (1_LOCAL@)\r
	- optimized inner interpreter by 15%\r
	- fix tester.fth failures\r

	- Fixed saving and restoring of TIB when nesting include files.\r
\r
V17\r
	- Fixed input of large floats.  0.7071234567 F.  used to fail.\r
\r
V16\r
	* Define PF_USER_CUSTOM if you are defining your own custom\r
	  'C' glue routines.  This will ifndef the published example.\r
	- Fixed warning in pf_cglue.c.\r
	- Fixed SDAD in savedicd.fth.  It used to generate bogus 'C' code\r
	  if called when (BASE != 10), as in HEX mode.\r
	- Fixed address comparisons in forget.fth and private.fth for\r
	  addresses above 0x80000000. Must be unsigned.\r
	- Call FREEZE at end of system.fth to initialize rfence.\r
	- Fixed 0.0 F. which used to leave 0.0 on FP stack.\r
	- Added FPICK ( n -- ) ( i*f -- i*f f[n] )\r
	- .S now prints hex numbers as unsigned.\r
	- Fixed internal number to text conversion for unsigned nums.\r
\r
V15 - 2/15/97\r
	* If you use PF_USER_FILEIO, you must now define PF_STDIN and PF_STDOUT\r
	  among other additions. See "pf_io.h".\r
	* COMPARE now matches ANS STRING word set!\r
	- Added PF_USER_INC1 and PF_USER_INC2 for optional includes\r
	  and host customization. See "pf_all.h".\r
	- Fixed more warnings.\r
	- Fixed >NAME and WORDS for systems with high "negative" addresses.\r
	- Added WORDS.LIKE utility.  Enter:   WORDS.LIKE EMIT\r
	- Added stack check after every word in high level interpreter.\r
	  Enter QUIT to enter high level interpreter which uses this feature.\r
	- THROW will no longer crash if not using high level interpreter.\r
	- Isolated all host dependencies into "pf_unix.h", "pf_win32.h",\r
	  "pf_mac.h", etc.  See "pf_all.h".\r
	- Added tests for CORE EXT, STRINGS words sets.\r
	- Added SEARCH\r
	- Fixed WHILE and REPEAT for multiple WHILEs.\r
	- Fixed .( ) for empty strings.\r
	- Fixed FATAN2 which could not compile on some systems (Linux gcc).\r
\r
V14 - 12/23/96\r
	* pforth command now requires -d before dictionary name.\r
	        Eg.   pforth -dcustom.dic test.fth\r
	* PF_USER_* now need to be defined as include file names.\r
	* PF_USER_CHARIO now requires different functions to be defined.\r
		See "csrc/pf_io.h".\r

\r
V13 - 12/15/96\r

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