5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * The FREQUENCIES and CROSSTABS commands can now generate barcharts.
11 * The FACTOR command can now perform PROMAX rotations.
13 * SPSS/PC+ system files are now supported on GET and other commands
14 that read SPSS system files. The pspp-convert program can now read
15 SPSS/PC+ system files. Writing the obsolete SPSS/PC+ system file
16 format is not supported.
18 * SYSFILE INFO can now read SPSS/PC+ system files and SPSS portable
21 * FREQUENCIES: A bug was fixed where an assertion failure occured
22 when an empty dataset was presented.
24 * The GRAPH command is now available. Initially it supports
25 scatterplots and histograms.
27 Changes from 0.8.3 to 0.8.4:
29 * Formatting of SYSFILE INFO output was made easier to read.
31 * Bug fixes, including the following notable ones:
33 - FREQUENCIES works properly for string variables. (This bug was
36 - CROSSTABS now correctly computes all of the measures that it
37 offers. Some measures have been removed because they were not
40 - The NPAR TESTS calculation of significance for the RUNS
41 subcommand has been corrected.
43 - Planned comparisons in ONEWAY ANOVA now correctly handle negative
46 - The COUNT command now correctly treats missing values as
49 - Conformance fixes to Open Document output format.
51 Changes from 0.8.2 to 0.8.3:
53 * Independent T-Tests displayed the standard error of the difference
54 and the confidence interval for the unequal variances case, where
55 the equal variances case should have been. This has been fixed.
57 * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
58 intervals for the coefficients to be printed.
60 * When DESCRIPTIVES calculates Z scores, it now omits cases filtered
61 by the current FILTER settings.
63 * PSPPIRE graphical user interface improvements:
65 - Dialog boxes with source variable lists can now choose the sort
66 order; right click and select from the popup menu.
68 - File|Open now allows an encoding to be selected for opening
71 - File|Display Data File Information|External File... now allows an
72 encoding to be selected.
74 - A problem with the Means dialog has been resolved (bug #41433).
76 - Several problems related to the input of spreadsheets have been
77 fixed (bug #41657, #41620
79 * System file related improvements:
81 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
82 pick an encoding for reading a system file that does not identify
85 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
86 character encoding of string data in the system file.
88 - Variable labels over 255 bytes long are now accepted without
89 truncation (bug #41863).
91 - System files that contain duplicate variable names may now be
92 read successfully (bug #41475).
94 Changes from 0.8.1 to 0.8.2:
96 * Charts are now rendered with colours from the Tango palette instead
97 of fully saturated primaries.
99 * Support for new system file variants:
101 - PSPP can now read and write ZCOMPRESSED system files, which
102 compress data much more effectively than older "compressed"
103 files. (The older format is still supported.)
105 - PSPP can now decrypt encrypted system files, using the new
106 pspp-convert utility. The encrypted system file format is
107 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
108 do not directly read or write this format.
110 * Missing values for long string variables are now read from and
111 written to system files in an SPSS-compatible fashion.
113 (Earlier versions of PSPP that supported missing values for long
114 string variables wrote them to system files in an SPSS-incompatible
115 way. To fix the problem, read the system file with this version of
116 PSPP and then save a new copy of it.)
118 * pspp-convert, a new standalone utility for converting SPSS system
119 and portable files to other formats, is now included. The initial
120 version supports comma-separated value files as output format.
121 pspp-convert can also decrypt encrypted system files.
125 - zlib is now a required dependency. (Previously it was optional.)
127 Changes from 0.8.0 to 0.8.1:
133 * Changes to existing commands:
135 - CROSSTABS: The requirement that one expected count must be less than five
136 before Fishers Exact Test will be reported has been removed.
138 * PSPPIRE graphical user interface improvements:
140 - A new set of icons has been contributed.
142 - Syntax windows now parse syntax in "auto" mode, which in practice
143 should mean that both "batch" and "interactive" syntax now works,
144 instead of just "interactive" syntax.
146 - The variable pane of data windows now include a Role column.
150 - System files written by IBM SPSS 21 are now read without warnings.
152 - System files written by "VOXCO INTERVIEWER 4.3" are now read
155 - PSPPIRE should now more gracefully handle syntax files that contain
158 Changes from 0.6.2 to 0.8.0:
164 - DATAFILE ATTRIBUTES
171 - LOGISTIC REGRESSION
175 - PRESERVE and RESTORE
179 - SAVE TRANSLATE to CSV and tab-delimited files
181 - VARIABLE ATTRIBUTES
183 * Changes to existing commands:
185 - AUTORECODE has a new GROUP subcommand.
187 - CROSSTABS has been re-implemented to fix numerous bugs.
189 - EXAMINE: /MISSING=LISTWISE is now the default.
191 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
192 contains an INCLUDE or INSERT command, substitutions are not
193 applied to the included file.
195 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
197 - HOST has been updated to use more modern syntax.
199 - Most commands that work with data files now support a new
202 - MISSING VALUES can now assign missing values to long string
205 - ONEWAY: the POSTHOC subcommand is now implemented.
207 - The following new subcommands to NPAR TESTS have been implemented:
208 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
209 MCNEMAR, SIGN, WILCOXON, and RUNS
211 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
212 DPROMPT subcommands. The defaults are now fixed values.
214 - SHOW now has a JOURNAL subcommand, to show the location of the
217 - VALUE LABELS can now assign value labels to long string
220 * Other language changes:
222 - The new DATASET commands replace the "scratch file" PSPP
223 extension, which is no longer supported.
225 - Strings may now include arbitrary Unicode code points specified
226 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
227 code point U+1D11E, the musical G clef character, may be
228 expressed as U'1D11E'.
230 See the "Tokens" section in the PSPP manual for more information.
232 - In previous versions of PSPP, in a string expressed in
233 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
234 bytes in the locale encoding. In this version of PSPP, X'hh'
235 syntax always expresses bytes in UTF-8 encoding.
237 See the "Tokens" section in the PSPP manual for more information.
239 * PSPPIRE graphical user interface improvements:
241 - Added support for non-ASCII characters in strings, labels and
244 - A "Split Window" function is available, which makes it easier to
245 see different parts of a large data file.
247 - Data files can now be opened by specifing their name as the first
248 argument. This means that on a properly configured desktop, double
249 clicking on an icon will open the file.
251 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
252 via using an "intelligent" application assistant dialog.
256 - The new "cairo" output driver supports output in PostScript, PDF,
257 and SVG formats. Its functionality is a superset of that of the
258 "postscript" driver, which has been removed. You must have Cairo
259 and Pango installed to build the "cairo" driver.
261 - Charts are now produced with Cairo and Pango, instead of libplot.
262 Without them, the new graphing features will not work. If you do
263 not have Cairo and Pango installed, you must run `configure' with
266 - The plain text output driver now properly supports multibyte UTF-8
267 characters, including double-width characters and combining
270 - Output to OpenDocument format is now supported.
272 - The HTML output is much improved.
274 * The "pspp" program has a new option --batch (or -b) that selects
275 "batch" syntax mode. In previous versions of PSPP this syntax mode
276 was the default. Now a new "auto" syntax mode is the default. In
277 "auto" mode, PSPP interprets most syntax files correctly regardless
278 of their intended syntax mode.
280 See the "Syntax Variants" section in the PSPP manual for more
283 * The "pspp" program has a new option --syntax-encoding that
284 specifies the encoding for syntax files listed on the command line,
285 as well as the default encoding for syntax files included with
286 INCLUDE or INSERT. The default is to accept the system locale
287 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
288 one the system file uses.
290 See the documentation for the INSERT command in the PSPP manual for
293 * Text data files that PRINT and WRITE creates now use the system
294 native line ends by default (CRLF on Windows, LF only elsewhere).
295 Use the new ENDS subcommand on FILE HANDLE to override the default.
297 * A new Perl module allows Perl programs to read and write PSPP
300 * A tutorial chapter has been added to the user manual.
302 Changes from 0.6.1 to 0.6.2:
306 - Dutch, thanks to Harry Thijssen.
308 - Brazilian Portuguese, thanks to Michel Boaventura.
310 Thanks for translations are also due to the coordinators at
311 translationproject.org.
313 * Statistical bug fixes:
315 - REGRESSION: Report correct standard error of the estimate (bug
318 - T-TEST: Report correct significance of paired sample T-test in
319 the common case (bug #26936) and corner cases. Thanks to Mike
320 Griffiths and Matej Cepl for reporting these bugs.
322 * Build fixes and changes:
324 - Fix build with GTK+ 2.17.4 and later.
326 - Make running "make" after running "configure" with different
327 settings reliably rebuild version.c.
329 - Cygwin and MinGW build fixes.
331 - Fixes for building with recent gnulib.
333 - The Makefile now honors two new variables, PSPP_LDFLAGS and
334 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
335 binaries, respectively. This makes building easier for some
338 - Fixes for "configure --enable-relocatable" (bug #25508).
340 * Data file bug fixes and changes:
342 - Fix reading text data files that contain a mix of white space
343 and commas. Now "a ,b" is treated as two fields containing "a"
344 and "b"; previously it was treated as three, with an empty field
347 - Fix writing corrupted .sav files on Windows.
349 - Fix writing variable labels longer than 252 bytes to save files.
350 Thanks to Robert Westlund for reporting this bug.
352 - Fix writing corrupted .por files (bug #26034).
354 - Fix reading .por files whose initial lines are not padded out
355 with spaces as expected.
357 - PSPP will no longer issue warnings about some .sav file records
358 or values that it does not understand. These warnings were
359 harmless, but needlessly alarmed some users.
361 - Fix crash reading empty string fields from PostgreSQL databases.
363 * Bug fixes that affect PSPP and PSPPIRE:
365 - Users may now control precision of output statistics. Instead
366 of hard coding the width and decimals of output numbers, respect
367 the default format in most instances. Counts are now normally
368 displayed with the format of the weight variable, if any.
370 - Fix crash when an INSERT command specifies the name of a file
371 that does not exist (bug #24569).
373 - Fix crash when CROSSTABS specifies a long-string variable (bugs
376 - Fix crash drawing pie charts with many segments.
378 - Fix crash when NUMERIC specifies an invalid format.
380 * PSPPIRE bug fixes and changes:
382 - On Windows, write the output file to the user's home directory
383 instead of the current directory, to better match user
386 - Some data editor fixes.
390 - Fix typo in BINOMIAL section of user manual (bug #25892).
392 Changes from 0.6.0 to 0.6.1:
394 * Statistical bug fixes:
396 - Report correct standardized regression coefficients in linear
397 regression output (bug #23567).
399 * Bug fixes that affect PSPP and PSPPIRE:
401 - Avoid crash with pie charts (bug #24014).
403 - Don't append % to count totals (bug #24003).
405 - Don't crash on bad input (bug #24031).
407 - Don't crash if "end data." is not left aligned (bug #24115).
409 - Change default workspace value to 64 MB, to avoid unnecessary
410 disk accesses on modern machines.
414 - Add ".sav" or ".por" suffix to filename when saving with Save_As
417 - Make it possible to reopen the output window on Windows (bug
420 - A POSIX regular expression library is now included and used
421 automatically if the host does not have one or has one that is
424 * Build fixes and changes:
426 - Work around bug in GSL that prevented build with recent GCC
427 versions without manually adding -fgnu89-inline to CFLAGS.
429 - Also warn about missing prerequisites as we encounter them (bug
432 - Distribute necessary files to allow users working from the
433 distributed tarball to configure with --enable-gui-tools.
435 - Append $(EXEEXT_FOR_BUILD) to output file name when building
436 q2c, fixing build problems on Windows.
438 - GSL 1.8 or later is now required.
440 - Build errors with --enable-relocatable were fixed.
442 * The German translations were removed, since native German speakers
443 found them too poor to be useful.
445 Changes from 0.4.0 to 0.6.0:
447 * The PSPP license is now version 3 or later of the GNU General
448 Public License. Previously, it was version 2 or later.
450 * PSPP now has a graphical interface, called PSPPIRE. This
451 interface allows you to enter data and variable definitions
452 interactively. Commands may be executed in syntax form, or by
453 using the interactive dialog boxes available from the dropdown
456 * A few sample syntax files are now included in the `examples'
459 * Numerous major and minor bugs have been fixed.
463 * The INSTALL file now reflects the details of how to install
464 PSPP. It is a tailored version of the generic installation
465 instructions, instead of a verbatim copy.
467 * iconv, which is ordinarily installed as part of a Unix-like
468 system, is now required. If you don't have it already, you can
469 install GNU libiconv (http://www.gnu.org/software/libiconv/).
471 * libxml2 and zlib are new optional dependencies. They are
472 required to use PSPP's support for reading Gnumeric files.
474 Statistical procedure changes:
476 * REGRESSION is a new procedure for fitting linear models to data
477 via least-squares estimation.
479 * NPAR TESTS is a new procedure for non-parametric tests. In this
480 release, it supports binomial and chi-square tests.
482 * RANK is a new procedure to rank variables. It supports numerous
485 * FREQUENCIES can now output histograms and pie charts. These
486 features were present in earlier releases, but not documented.
488 User interface changes:
490 * In many situations where PSPP once terminated with a fatal
491 error, PSPP now recovers and continues execution.
493 * PSPP is now able to start up and run even if it cannot find its
496 * Journaling of interactive commands to a disk file is now
497 implemented. By default, journaling is enabled, to a file named
498 `pspp.jnl' in the current directory. SET JOURNAL may be used to
501 * The use of `+' between syntax file names on the command line to
502 prevent the dictionary from being cleared between their
503 executions is no longer supported. All syntax files are now
504 executed as if `+' had been specified.
506 * The -d/--define and -u/--undef command line options are no
507 longer supported. Instead, use /usr/bin/env or shell primitives
508 to define or clear environment variables before invoking PSPP.
510 * If a syntax file named named `rc' is found in a configuration
511 directory (such as $HOME/.pspp), it is executed before any
512 syntax file specified on the command line. The -r or
513 --no-statrc command line option may be used to disable this
518 * Output configuration options have changed. Please refer to the
519 manual for a full description of the available options.
521 In consequence, you will need to reinstall your "devices" file.
522 "make install" will do this for you.
524 * Most error messages are now written to PSPP output files by
525 default. SET ERROR can be used to disable this behavior.
527 * When invoked interactively, PSPP now by default produces output
528 on the terminal, piping it through the "more" program.
529 Previously, by default output was written only to file
530 pspp.list. On most terminals, the page length used for output
531 automatically adapts to the terminal size, even if the terminal
536 - This driver now supports charts in output. Charts are written
537 as separate files that the main output file refers to. By
538 default, charts are written in PNG format to files named
539 pspp-1.png, pspp-2.png, and so on.
541 - Configurations are provided that use VT100 (and xterm)
542 line-drawing characters in tables. The option "-o list-vt100"
543 requests use of this device for output to pspp.list.
547 - The default paper size is now determined using the PAPERSIZE
548 environment variable, or the LC_PAPER locale category on
549 systems that support it. If these are not set, the default is
550 now A4, instead of US letter. To make US letter the default,
551 set PAPERSIZE to "letter" in your environment.
553 - Font metrics are now read from AFM files, instead of
554 Groff-format metrics files. PostScript fonts can now be
557 In consequence, you will need to install an AFM file for each
558 font used in PostScript output. "make install" will install
559 AFM files for the standard PostScript fonts, including the
560 ones that the PostScript driver uses by default.
562 - Standard paper sizes no longer need to be specified through a
563 configuration file. The "papersize" configuration file is no
564 longer needed, or supported.
566 - The PostScript prologue is no longer obtained from the
567 "ps-prologue" configuration file. This configuration file is
568 no longer needed, or supported.
572 - The HTML prologue is no longer obtained from the
573 "html-prologue" configuration file. This configuration file
574 is no longer needed, or supported.
576 Command language changes:
578 * The following commands are new:
580 - GET DATA, which currently supports reading Gnumeric files and
581 text data files. It will be extended later to read other
582 types of foreign data.
584 - CD, to change the current directory.
586 - INSERT, to execute a syntax file.
588 - DELETE VARIABLES, to remove variables from the active file
591 - ADD DOCUMENT, to add text to active file documents.
593 - CLOSE FILE HANDLE (a PSPP extension; see below).
595 - XEXPORT, a PSPP extension that is a transformation equivalent
598 * The following functions for transformation expressions are new:
600 - DATEDIFF, for computing the difference of two dates.
602 - DATESUM, for advancing a date by a specified duration.
604 - VALUELABEL, to obtain the value label for a value.
606 * PSPP now supports very long string variables (over 255 bytes
609 * MATCH FILES now supports the FIRST and LAST subcommands.
611 * Previous versions of PSPP prohibited using commands to both read and
612 write a single file at the same time. Now, PSPP allows this, and
613 the new version of the file atomically replaces the old version.
615 * The following commands are no longer available. They will be
616 re-implemented in a later release:
618 - CLEAR TRANSFORMATIONS
624 * The PROCESS IF command, which was deprecated, has been removed.
625 You may replace any usage of it by SELECT IF following
626 TEMPORARY, which has the same effect.
628 * The output format for variables created by VECTOR may now be
629 specified as part of the VECTOR syntax.
631 "Scratch files", a new PSPP extension:
633 A scratch file, like a system file, consists of a dictionary and
634 any number of cases. Small scratch files are stored in memory;
635 one that grows too large is written to disk. By default, any file
636 handle whose name begins with # is assumed to refer to a scratch
639 Scratch files can be used just about anywhere a system or portable
640 file can be used. Also, portable files are now allowed in most
641 places that system files were allowed in previous PSPP version.
643 A new CLOSE FILE HANDLE command allows the storage associated with
644 scratch files to be freed. It also allows file handles to be
645 reassigned to new files.
647 For more information on scratch files, refer to the "File Handles"
648 section in the PSPP manual. For specifics of what commands now
649 allow what kinds of files to be specified, refer to the
650 documentation on those particular commands.
654 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
655 translation, are now supported. Use FILE HANDLE to specify the
656 format of these files.
658 * Little-endian, big-endian, and VAX-endian formats are now
659 supported for integer binary formats when reading and writing
660 data files. The new RIB and WIB subcommands on the SET command
661 control endianness of integer data. The default is the host's
664 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
665 floating point binary formats when reading and writing data
666 files. The new RRB and WRB subcommands on the SET command
667 control the floating point format. The default is the host's
668 native floating point format.
670 * DATA LIST now supports the SKIP subcommand, to skip records at
671 the beginning of a file. For compatibility, DATA LIST now
672 treats N format as F format for FREE and LIST format input.
674 * The SAVE and XSAVE commands now support the UNSELECTED,
675 PERMISSIONS, NAMES, and MAP subcommands.
677 * The EXPORT command has been re-implemented to obtain better
678 results. Support for the UNSELECTED, DIGITS, and TYPE
679 subcommands has been added.
681 * For compatibility, PRINT now inserts a space at the beginning of
682 every output line, even lines that would otherwise be blank,
683 when OUTFILE is specified. (The behavior of WRITE is
686 * For compatibility, PRINT EJECT now inserts the digit `1' at the
687 beginning of each line that should begin a new page.
689 * For compatibility, WRITE now outputs the system-missing value as
690 a field filled with spaces. Binary formats are an exception.
691 (The behavior of PRINT is unchanged.)
695 * Input and output format descriptions have been rewritten. They
696 now precisely describe what is accepted on input and written on
699 * The descriptions of the PSPP system and portable file formats
700 have been extensively revised and improved.
702 For developers, the build system now requires Autoconf 2.60 and
705 Changes from 0.3.0 to 0.4.0:
707 Changes in build dependencies:
709 * The GNU Scientific Library (libgsl), version 1.6 or later, is
712 * libplot from GNU plotutils is optional. Without it, the new
713 graphing features will not work. If you do not have it
714 installed, you must run `configure' with --without-libplot.
716 * libgmp2 is no longer a dependency.
718 Newly implemented commands and statistical features:
720 * EXAMINE, including its graphing features.
722 * FREQUENCIES now supports percentiles.
730 * SORT CASES now sorts stably, that is, two cases with equal sort
731 criteria will be in the same relative order before and after the
734 * T-TEST (re-written).
736 * DATE and USE. These commands are parsed but otherwise ignored,
737 to enhance compatibility with certain command files that invoke
740 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
741 currently have no effect on PSPP output, but their values are
742 written to and read from system files and thus may affect
743 third-party software.
745 * SET EPOCH implemented.
747 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
750 * FILE HANDLE now supports custom tab widths.
752 Long variable names (and other identifiers) are now supported. Up
753 to the first 64 bytes of each identifier is significant. PSPP now
754 reads and writes system files compatible with SPSS version 12.
756 New --algorithm and --syntax command line options allow
757 SPSS-compatible or enhanced modes to be selected.
759 Support for transformation expressions has been rewritten and
760 significantly improved. Refer to the manual for details.
762 Calculation of moments (mean, standard deviation, kurtosis,
763 skewness) has been rewritten and should now be more accurate. In
764 --algorithm=enhanced mode moments may be more accurate than SPSS in
767 Numerous bugs have been fixed, too many to mention here. Many new
768 tests have been added, leading to the discovery and fixing of many
771 The ASCII output driver can now squeeze multiple blank lines into
774 Much of the code has been rewritten and refactored. It is now much
777 The FILE TYPE and REPEATING DATA commands have been disabled for
778 this release because their implementations were deemed too buggy to
779 be useful. They will be fixed and replaced in a future release.
781 New pspp-mode for Emacs (in pspp-mode.el).
783 Added rudimentary command-line completion for interactive input.
785 lib/julcal and lib/dcdflib are no longer used, so they have been
788 For developers, the build system now requires Autoconf 2.58 and
789 Automake 1.7. The included gettext has been updated to version
792 Some reports state that Texinfo 4.8, the latest version, may be
793 necessary to successfully format the documentation on some systems.
795 Version 0.3.0 changes since 0.2.3:
799 * Using alphanumeric variables in functions under AGGREGATE
802 * Under certain circumstances, the final case would be omitted
803 from the results of an AGGREGATE operation. Fixed.
805 * Undefined behavior was invoked by referencing a freed pointer
806 under certain circumstances. Fixed.
808 * A wrong record size was displayed when paging the active file to
811 * Not having enough temporary space for sorting caused a core
814 * Syntax errors in function descriptions on AGGREGATE caused core
817 * A null pointer was dereferenced, causing a core dump, when
818 PERCENTILES was specified on FREQUENCIES. This fixes the
819 problem, but PSPP still doesn't calculate percentiles.
821 * SORT always sorted in ascending order. Fixed.
823 * Some minor memory leaks in the expression parser were removed.
825 * Many assertions fixed for strict ANSI C compliance.
829 * SET ECHO ON now implemented, but turned off by default.
831 * PRINT specifier supported on END REPEAT.
835 * System libgmp2 library is used if installed instead of
836 unconditionally using the included libgmp2 subset.
838 * Extensive code cleanup, which continues.
840 * Added CORRELATIONS command parser, but not implemented.
842 Version 0.2.3 changes since 0.2.2:
846 * SPLIT FILE with a string variable caused a core dump. Fixed.
848 * Nested INCLUDEs didn't work. Fixed.
850 * The MATCH FILES procedure set the values of variables not present
851 to 0. It should have been SYSMIS. This is now fixed.
853 * The REMARK command was too aggressive about skipping lines. It
854 didn't like being the last command in a file.
856 * Comment parsing wasn't consistent with the rest of the code in its
857 idea of where one command ends and another starts. This meant
858 that sometimes commands would be mysteriously ignored. Thanks to
859 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
861 * The TABLE subcommand on MATCH FILES worked only erratically at
862 best. This fixes it. Thanks to Dr. Dirk Melcher
863 <BZN-mdksh@t-online.de> for reporting this bug.
865 * VARIABLE LABELS rejected a slash before the first variable
866 specification, contradicting the documentation. Thanks to Walter
867 M. Gray <graywm@northernc.on.ca> for reporting this bug.
869 * Because of an incorrect optimization in memory allocation,
870 CROSSTABS sometimes segfaulted when asked to output multiple
871 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
874 * CROSSTABS didn't display value labels for column and row
875 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
878 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
879 <BZN-mdksh@t-online.de> for reporting this bug.

887 M. Gray <graywm@northernc.on.ca> for reporting this bug.
889 * Because of an incorrect optimization in memory allocation,
890 CROSSTABS sometimes segfaulted when asked to output multiple
891 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
894 * CROSSTABS didn't display value labels for column and row
895 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
898 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
899 <BZN-mdksh@t-online.de> for reporting this bug.
901 * MATCH FILES corrupted memory and dumped core on some syntax
904 * MATCH FILES should set numeric values not available to the
905 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
906 <BZN-mdksh@t-online.de> for reporting this bug.
908 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
909 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
913 * Some systems didn't like the way open_file was coded. Thanks to
914 Hankin <hankin@rogue.consultco.com> for pointing this out.
916 * The SAVE procedure didn't save long string variables properly.
917 Fixed by this patch. Thanks to Hankin
918 <hankin@rogue.consultco.com> for this patch.
920 * Minor documentation fixes for MATCH FILES.
922 Version 0.2.2 changes since 0.2.1:
926 * Fix behavior of PRINT SPACE for negative arguments.
928 * Fix reading some unusual system files.
930 * Fix LIST problems with very long variables. Thanks to Hankin
931 <hankin@dunno.com> for this bug report.
933 * Fix problems with some string format specifiers.
935 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
936 <BZN-mdksh@t-online.de> for reporting this bug.
938 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
939 Hankin <hankin@dunno.com> again on this one.
941 * Sometimes you may encounter a PSPP script that has to be
942 interpreted in interactive mode. Now you can use the -i flag to
945 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
946 `unused variable' warnings under gcc 2.7.2.3, fixing this will
951 * The files in gmp need the internationalization directory in
952 their include path. Thanks to OKUJI Yoshinori
953 <okuji@kuicr.kyoto-u.ac.jp> for pointing this out.
955 Version 0.2.1 changes since 0.2.0:
959 * Remember to include examples/ directory in distribution :-)
961 * Fixed gmp compile problems for some non-i386 architectures.
962 Thanks to Hans Olav Eggestad <olav@jordforsk.nlh.no> and others
965 * DATA LIST FREE and DATA LIST LIST parsing of input files is now
966 matches the documented behavior exactly, and error messages are
967 more helpful. Thanks to Mark H. Wood <mwood@IUPUI.Edu>.
