Recent Releases Include

V23 - 7/20/2008

• Reorganized for Google Code project.
• 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.
• 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 - 8/98

• 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 - 4/7/98

• 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.
• Added 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.
