20 | V23 7/20/2008\r |
21 | - Reorganized for Google Code project.\r |
22 | \r |
23 | V22 (unreleased)\r |
24 | - Added command line history and cursor control words.\r |
25 | - Sped up UM* and M* by a factor of 3. Thanks to Steve Green for suggested algorithm.\r |
26 | - Modified ACCEPT so that a line at the end of a file that does NOT have a line\r |
27 | terminator will now be processed.\r |
28 | - Use _getch(), _putch(), and _kbhit() so that KEY, EMIT and ?TERMINAL will work on PC.\r |
6b91cb54 |
29 | - Fixed : foo { -- } 55 ; - Was entering local frame but not exiting. Now prints error.\r |
bb6b2dcd |
30 | - Redefined MAKE_ID to protect it from 16 bit ints\r |
31 | - John Providenza says "If you split local variables onto 2 lines, PForth crashes." Fixed. Also allow \\r |
32 | - Fixed float evaluation in EVALUATE in "quit.fth".\r |
33 | - Flush register cache for ffColon and ffSemiColon to prevent stack warnings from ;\r |
34 | \r |
1cb310e6 |
35 | V21 - 9/16/1998\r |
bb6b2dcd |
36 | - Fixed some compiler warnings.\r |
37 | \r |
38 | V20\r |
39 | - Expand PAD for ConvertNumberToText so "-1 binary .s" doesn't crash.\r |
40 | Thank you Michael Connor of Vancouver for reporting this bug.\r |
41 | \r |
42 | - Removed FDROP in REPRESENT to fix stack underflow after "0.0 F.".\r |
43 | Thank you Jim Rosenow of Minnesota for reporting this bug.\r |
44 | - Changed pfCharToLower to function to prevent macro expansion bugs under VXWORKS\r |
45 | Thank you Jim Rosenow of Minnesota for reporting this bug.\r |
46 | \r |
47 | - "0.0 F~" now checks actual binary encoding of floats. Before this it used to just\r |
48 | compare value which was incorrect. Now "0.0 -0.0 0.0 F~" returns FALSE.\r |
49 | \r |
50 | - Fixed definition of INPUT$ in tutorial.\r |
51 | Thank you Hampton Miller of California for reporting this bug.\r |
52 | \r |
53 | - Added support for producing a target dictionary with a different\r |
54 | Endian-ness than the host CPU. See PF_BIG_ENDIAN_DIC and PF_LITTLE_ENDIAN_DIC.\r |
55 | \r |
56 | - PForth kernel now comes up in a mode that uses BASE for numeric input when\r |
57 | started with "-i" option. It used to always consider numeric input as HEX.\r |
58 | Initial BASE is decimal. \r |
59 | \r |
1cb310e6 |
60 | V19 4/1998\r |
bb6b2dcd |

71 | For example: : F. (F.) TYPE SPACE ;\r |
72 | - Reversed order that values are placed on return stack in 2>R\r |
73 | so that it matches ANS standard. 2>R is now same as SWAP >R >R\r |
74 | Thank you Leo Wong for reporting this bug.\r |
75 | \r |

94 | 'C' glue routines. This will ifndef the published example.\r |
95 | - Fixed warning in pf_cglue.c.\r |
96 | - Fixed SDAD in savedicd.fth. It used to generate bogus 'C' code\r |
97 | if called when (BASE != 10), as in HEX mode.\r |
98 | - Fixed address comparisons in forget.fth and private.fth for\r |
99 | addresses above 0x80000000. Must be unsigned.\r |

116 | Enter QUIT to enter high level interpreter which uses this feature.\r |
117 | - THROW will no longer crash if not using high level interpreter.\r |
118 | - Isolated all host dependencies into "pf_unix.h", "pf_win32.h",\r |
119 | "pf_mac.h", etc. See "pf_all.h".\r |

136 | \r |
137 | V13 - 12/15/96\r |
138 | - Add "extern 'C' {" to pf_mem.h for C++\r |
139 | - Separate PF_STATIC_DIC from PF_NO_FILEIO so that we can use a static\r |
140 | dictionary but also have file I/O.\r |
141 | - Added PF_USER_FILEIO, PF_USER_CHARIO, PF_USER_CLIB.\r |
142 | - INCLUDE now aborts if file not found.\r |
