8 Version 0.3.0 changes since 0.2.3:
12 * Using alphanumeric variables in functions under AGGREGATE
15 * Under certain circumstances, the final case would be omitted
16 from the results of an AGGREGATE operation. Fixed.
18 * Undefined behavior was invoked by referencing a freed pointer
19 under certain circumstances. Fixed.
21 * A wrong record size was displayed when paging the active file to
24 * Not having enough temporary space for sorting caused a core
27 * Syntax errors in function descriptions on AGGREGATE caused core
30 * A null pointer was dereferenced, causing a core dump, when
31 PERCENTILES was specified on FREQUENCIES. This fixes the
32 problem, but PSPP still doesn't calculate percentiles.
34 * SORT always sorted in ascending order. Fixed.
36 * Some minor memory leaks in the expression parser were removed.
38 * Many assertions fixed for strict ANSI C compliance.
42 * SET ECHO ON now implemented, but turned off by default.
44 * PRINT specifier supported on END REPEAT.
48 * System libgmp2 library is used if installed instead of
49 unconditionally using the included libgmp2 subset.
51 * Extensive code cleanup, which continues.
53 * Added CORRELATIONS command parser, but not implemented.
55 Version 0.2.3 changes since 0.2.2:
59 * SPLIT FILE with a string variable caused a core dump. Fixed.
61 * Nested INCLUDEs didn't work. Fixed.
63 * The MATCH FILES procedure set the values of variables not present
64 to 0. It should have been SYSMIS. This is now fixed.
66 * The REMARK command was too aggressive about skipping lines. It
67 didn't like being the last command in a file.
69 * Comment parsing wasn't consistent with the rest of the code in its
70 idea of where one command ends and another starts. This meant
71 that sometimes commands would be mysteriously ignored. Thanks to
72 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
74 * The TABLE subcommand on MATCH FILES worked only erratically at
75 best. This fixes it. Thanks to Dr. Dirk Melcher
76 <BZN-mdksh@t-online.de> for reporting this bug.
78 * VARIABLE LABELS rejected a slash before the first variable
79 specification, contradicting the documentation. Thanks to Walter
80 M. Gray <graywm@northernc.on.ca> for reporting this bug.
82 * Because of an incorrect optimization in memory allocation,
83 CROSSTABS sometimes segfaulted when asked to output multiple
84 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
87 * CROSSTABS didn't display value labels for column and row
88 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
91 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
92 <BZN-mdksh@t-online.de> for reporting this bug.
94 * The TABLE subcommand on MATCH FILES worked only erratically at
95 best. This fixes it. Thanks to Dr. Dirk Melcher
96 <BZN-mdksh@t-online.de> for reporting this bug.
98 * VARIABLE LABELS rejected a slash before the first variable
99 specification, contradicting the documentation. Thanks to Walter
100 M. Gray <graywm@northernc.on.ca> for reporting this bug.
102 * Because of an incorrect optimization in memory allocation,
103 CROSSTABS sometimes segfaulted when asked to output multiple
104 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
107 * CROSSTABS didn't display value labels for column and row
108 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
111 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
112 <BZN-mdksh@t-online.de> for reporting this bug.
114 * MATCH FILES corrupted memory and dumped core on some syntax
117 * MATCH FILES should set numeric values not available to the
118 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
119 <BZN-mdksh@t-online.de> for reporting this bug.
121 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
122 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
126 * Some systems didn't like the way open_file was coded. Thanks to
127 Hankin <hankin@rogue.consultco.com> for pointing this out.
129 * The SAVE procedure didn't save long string variables properly.
130 Fixed by this patch. Thanks to Hankin
131 <hankin@rogue.consultco.com> for this patch.
133 * Minor documentation fixes for MATCH FILES.
135 Version 0.2.2 changes since 0.2.1:
139 * Fix behavior of PRINT SPACE for negative arguments.
141 * Fix reading some unusual system files.
143 * Fix LIST problems with very long variables. Thanks to Hankin
144 <hankin@dunno.com> for this bug report.
146 * Fix problems with some string format specifiers.
148 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
149 <BZN-mdksh@t-online.de> for reporting this bug.
151 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
152 Hankin <hankin@dunno.com> again on this one.
154 * Sometimes you may encounter a PSPP script that has to be
155 interpreted in interactive mode. Now you can use the -i flag to
158 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
159 `unused variable' warnings under gcc 2.7.2.3, fixing this will
164 * The files in gmp need the internationalization directory in
165 their include path. Thanks to OKUJI Yoshinori
166 <okuji@kuicr.kyoto-u.ac.jp> for pointing this out.
168 Version 0.2.1 changes since 0.2.0:
172 * Remember to include examples/ directory in distribution :-)
174 * Fixed gmp compile problems for some non-i386 architectures.
175 Thanks to Hans Olav Eggestad <olav@jordforsk.nlh.no> and others
178 * DATA LIST FREE and DATA LIST LIST parsing of input files is now
179 matches the documented behavior exactly, and error messages are
180 more helpful. Thanks to Mark H. Wood <mwood@IUPUI.Edu>.
182 Version 0.2.0 changes since 0.1.0:
184 Procedures now implemented:
185 * CROSSTABS. Please see documentation for caveats.
