3 | Documentation for pForth at http://www.softsynth.com/pforth/\r |
4 | \r |
5 | V23 7/20/2008\r |
6 | - Reorganized for Google Code project.\r |
7 | \r |
8 | V22 (unreleased)\r |
9 | - Added command line history and cursor control words.\r |
10 | - Sped up UM* and M* by a factor of 3. Thanks to Steve Green for suggested algorithm.\r |
11 | - Modified ACCEPT so that a line at the end of a file that does NOT have a line\r |
12 | terminator will now be processed.\r |
13 | - Use _getch(), _putch(), and _kbhit() so that KEY, EMIT and ?TERMINAL will work on PC.\r |
14 | - Fixed : foo { -- } 55 ; - was entering local frame but not exiting.\r |
15 | - Redefined MAKE_ID to protect it from 16 bit ints\r |
16 | - John Providenza says "If you split local variables onto 2 lines, PForth crashes." Fixed. Also allow \\r |
17 | - Fixed float evaluation in EVALUATE in "quit.fth".\r |
18 | - Flush register cache for ffColon and ffSemiColon to prevent stack warnings from ;\r |
19 | \r |
20 | V21 - 9/16/98\r |
21 | - Fixed some compiler warnings.\r |
22 | \r |
23 | V20\r |
24 | - Expand PAD for ConvertNumberToText so "-1 binary .s" doesn't crash.\r |
25 | Thank you Michael Connor of Vancouver for reporting this bug.\r |
26 | \r |
27 | - Removed FDROP in REPRESENT to fix stack underflow after "0.0 F.".\r |
28 | Thank you Jim Rosenow of Minnesota for reporting this bug.\r |
29 | - Changed pfCharToLower to function to prevent macro expansion bugs under VXWORKS\r |
30 | Thank you Jim Rosenow of Minnesota for reporting this bug.\r |
31 | \r |
32 | - "0.0 F~" now checks actual binary encoding of floats. Before this it used to just\r |
33 | compare value which was incorrect. Now "0.0 -0.0 0.0 F~" returns FALSE.\r |
34 | \r |
35 | - Fixed definition of INPUT$ in tutorial.\r |
36 | Thank you Hampton Miller of California for reporting this bug.\r |
37 | \r |
38 | - Added support for producing a target dictionary with a different\r |
39 | Endian-ness than the host CPU. See PF_BIG_ENDIAN_DIC and PF_LITTLE_ENDIAN_DIC.\r |
40 | \r |
41 | - PForth kernel now comes up in a mode that uses BASE for numeric input when\r |
42 | started with "-i" option. It used to always consider numeric input as HEX.\r |
43 | Initial BASE is decimal. \r |
44 | \r |
45 | V19 4/98\r |
46 | \r |
47 | - Warn if local var name matches dictionary, : foo { count -- } ;\r |
48 | - TO -> and +-> now parse input stream. No longer use to-flag.\r |
49 | - TO -> and +-> now give error if used with non-immediate word.\r |
50 | - Added (FLITERAL) support to SEE.\r |
51 | - Aded TRACE facility for single step debugging of Forth words.\r |
52 | - Added stub for ?TERMINAL and KEY? for embedded systems.\r |
53 | - Added PF_NO_GLOBAL_INIT for no reliance on global initialization.\r |
54 | - Added PF_USER_FLOAT for customization of FP support.\r |
55 | - Added floating point to string conversion words (F.) (FS.) (FE.)\r |
56 | For example: : F. (F.) TYPE SPACE ;\r |
57 | - Reversed order that values are placed on return stack in 2>R\r |
58 | so that it matches ANS standard. 2>R is now same as SWAP >R >R\r |
59 | Thank you Leo Wong for reporting this bug.\r |
60 | \r |
61 | - Added PF_USER_INIT and PF_USER_TERM for user definable init and term calls.\r |
62 | \r |
63 | - FIXED memory leak in pfDoForth()\r |
64 | \r |

72 | - Fixed saving and restoring of TIB when nesting include files.\r |
73 | \r |

75 | - Fixed input of large floats. 0.7071234567 F. used to fail.\r |
76 | \r |
77 | V16\r |
78 | * Define PF_USER_CUSTOM if you are defining your own custom\r |
79 | 'C' glue routines. This will ifndef the published example.\r |
80 | - Fixed warning in pf_cglue.c.\r |
81 | - Fixed SDAD in savedicd.fth. It used to generate bogus 'C' code\r |
82 | if called when (BASE != 10), as in HEX mode.\r |
83 | - Fixed address comparisons in forget.fth and private.fth for\r |
84 | addresses above 0x80000000. Must be unsigned.\r |
85 | - Call FREEZE at end of system.fth to initialize rfence.\r |
86 | - Fixed 0.0 F. which used to leave 0.0 on FP stack.\r |
87 | - Added FPICK ( n -- ) ( i*f -- i*f f[n] )\r |
88 | - .S now prints hex numbers as unsigned.\r |
89 | - Fixed internal number to text conversion for unsigned nums.\r |
90 | \r |
91 | V15 - 2/15/97\r |
92 | * If you use PF_USER_FILEIO, you must now define PF_STDIN and PF_STDOUT\r |
93 | among other additions. See "pf_io.h".\r |
94 | * COMPARE now matches ANS STRING word set!\r |
95 | - Added PF_USER_INC1 and PF_USER_INC2 for optional includes\r |
96 | and host customization. See "pf_all.h".\r |
97 | - Fixed more warnings.\r |

99 | - Added WORDS.LIKE utility. Enter: WORDS.LIKE EMIT\r |
100 | - Added stack check after every word in high level interpreter.\r |
101 | Enter QUIT to enter high level interpreter which uses this feature.\r |
102 | - THROW will no longer crash if not using high level interpreter.\r |
103 | - Isolated all host dependencies into "pf_unix.h", "pf_win32.h",\r |
104 | "pf_mac.h", etc. See "pf_all.h".\r |
105 | - Added tests for CORE EXT, STRINGS words sets.\r |
106 | - Added SEARCH\r |
107 | - Fixed WHILE and REPEAT for multiple WHILEs.\r |
108 | - Fixed .( ) for empty strings.\r |

118 | file with main().\r |
119 | - Fix build with PF_NO_INIT\r |
120 | - Makefile now has target for embedded dictionary, "gmake pfemb".\r |
121 | \r |

123 | - Add "extern 'C' {" to pf_mem.h for C++\r |
124 | - Separate PF_STATIC_DIC from PF_NO_FILEIO so that we can use a static\r |
125 | dictionary but also have file I/O.\r |
126 | - Added PF_USER_FILEIO, PF_USER_CHARIO, PF_USER_CLIB.\r |
127 | - INCLUDE now aborts if file not found.\r |
128 | - Add +-> which allows you to add to a local variable, like +! .\r |
129 | - VALUE now works properly as a self fetching constant.\r |
130 | - Add CODE-SIZE and HEADERS-SIZE which lets you resize\r |
131 | dictionary saved using SAVE-FORTH.\r |

133 | - Fixed bug in local variables that caused problems if compilation\r |
134 | aborted in a word with local variables.\r |
135 | - Added SEE which "disassembles" Forth words. See "see.fth".\r |
136 | - Added PRIVATE{ which can be used to hide low level support\r |
137 | words. See "private.fth".\r |
138 | \r |
139 | V12 - 12/1/96\r |
140 | - Advance pointers in pfCopyMemory() and pfSetMemory()\r |
