5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * The FACTOR command can now perform PROMAX rotations.
11 * SPSS/PC+ system files are now supported on GET and other commands
12 that read SPSS system files. The pspp-convert program can now read
13 SPSS/PC+ system files. Writing the obsolete SPSS/PC+ system file
14 format is not supported.
16 * SYSFILE INFO can now read SPSS/PC+ system files and SPSS portable
19 * FREQUENCIES: A bug was fixed where an assertion failure occured
20 when an empty dataset was presented.
22 * The GRAPH command is now available. Initially it supports
23 scatterplots and histograms.
25 Changes from 0.8.3 to 0.8.4:
27 * Formatting of SYSFILE INFO output was made easier to read.
29 * Bug fixes, including the following notable ones:
31 - FREQUENCIES works properly for string variables. (This bug was
34 - CROSSTABS now correctly computes all of the measures that it
35 offers. Some measures have been removed because they were not
38 - The NPAR TESTS calculation of significance for the RUNS
39 subcommand has been corrected.
41 - Planned comparisons in ONEWAY ANOVA now correctly handle negative
44 - Conformance fixes to Open Document output format.
46 Changes from 0.8.2 to 0.8.3:
48 * Independent T-Tests displayed the standard error of the difference
49 and the confidence interval for the unequal variances case, where
50 the equal variances case should have been. This has been fixed.
52 * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
53 intervals for the coefficients to be printed.
55 * When DESCRIPTIVES calculates Z scores, it now omits cases filtered
56 by the current FILTER settings.
58 * PSPPIRE graphical user interface improvements:
60 - Dialog boxes with source variable lists can now choose the sort
61 order; right click and select from the popup menu.
63 - File|Open now allows an encoding to be selected for opening
66 - File|Display Data File Information|External File... now allows an
67 encoding to be selected.
69 - A problem with the Means dialog has been resolved (bug #41433).
71 - Several problems related to the input of spreadsheets have been
72 fixed (bug #41657, #41620
74 * System file related improvements:
76 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
77 pick an encoding for reading a system file that does not identify
80 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
81 character encoding of string data in the system file.
83 - Variable labels over 255 bytes long are now accepted without
84 truncation (bug #41863).
86 - System files that contain duplicate variable names may now be
87 read successfully (bug #41475).
89 Changes from 0.8.1 to 0.8.2:
91 * Charts are now rendered with colours from the Tango palette instead
92 of fully saturated primaries.
94 * Support for new system file variants:
96 - PSPP can now read and write ZCOMPRESSED system files, which
97 compress data much more effectively than older "compressed"
98 files. (The older format is still supported.)
100 - PSPP can now decrypt encrypted system files, using the new
101 pspp-convert utility. The encrypted system file format is
102 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
103 do not directly read or write this format.
105 * Missing values for long string variables are now read from and
106 written to system files in an SPSS-compatible fashion.
108 (Earlier versions of PSPP that supported missing values for long
109 string variables wrote them to system files in an SPSS-incompatible
110 way. To fix the problem, read the system file with this version of
111 PSPP and then save a new copy of it.)
113 * pspp-convert, a new standalone utility for converting SPSS system
114 and portable files to other formats, is now included. The initial
115 version supports comma-separated value files as output format.
116 pspp-convert can also decrypt encrypted system files.
120 - zlib is now a required dependency. (Previously it was optional.)
122 Changes from 0.8.0 to 0.8.1:
128 * Changes to existing commands:
130 - CROSSTABS: The requirement that one expected count must be less than five
131 before Fishers Exact Test will be reported has been removed.
133 * PSPPIRE graphical user interface improvements:
135 - A new set of icons has been contributed.
137 - Syntax windows now parse syntax in "auto" mode, which in practice
138 should mean that both "batch" and "interactive" syntax now works,
139 instead of just "interactive" syntax.
141 - The variable pane of data windows now include a Role column.
145 - System files written by IBM SPSS 21 are now read without warnings.
147 - System files written by "VOXCO INTERVIEWER 4.3" are now read
150 - PSPPIRE should now more gracefully handle syntax files that contain
153 Changes from 0.6.2 to 0.8.0:
159 - DATAFILE ATTRIBUTES
166 - LOGISTIC REGRESSION
170 - PRESERVE and RESTORE
174 - SAVE TRANSLATE to CSV and tab-delimited files
176 - VARIABLE ATTRIBUTES
178 * Changes to existing commands:
180 - AUTORECODE has a new GROUP subcommand.
182 - CROSSTABS has been re-implemented to fix numerous bugs.
184 - EXAMINE: /MISSING=LISTWISE is now the default.
186 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
187 contains an INCLUDE or INSERT command, substitutions are not
188 applied to the included file.
190 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
192 - HOST has been updated to use more modern syntax.
194 - Most commands that work with data files now support a new
197 - MISSING VALUES can now assign missing values to long string
200 - ONEWAY: the POSTHOC subcommand is now implemented.
202 - The following new subcommands to NPAR TESTS have been implemented:
203 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
204 MCNEMAR, SIGN, WILCOXON, and RUNS
206 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
207 DPROMPT subcommands. The defaults are now fixed values.
209 - SHOW now has a JOURNAL subcommand, to show the location of the
212 - VALUE LABELS can now assign value labels to long string
215 * Other language changes:
217 - The new DATASET commands replace the "scratch file" PSPP
218 extension, which is no longer supported.
220 - Strings may now include arbitrary Unicode code points specified
221 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
222 code point U+1D11E, the musical G clef character, may be
223 expressed as U'1D11E'.
225 See the "Tokens" section in the PSPP manual for more information.
227 - In previous versions of PSPP, in a string expressed in
228 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
229 bytes in the locale encoding. In this version of PSPP, X'hh'
230 syntax always expresses bytes in UTF-8 encoding.
232 See the "Tokens" section in the PSPP manual for more information.
234 * PSPPIRE graphical user interface improvements:
236 - Added support for non-ASCII characters in strings, labels and
239 - A "Split Window" function is available, which makes it easier to
240 see different parts of a large data file.
242 - Data files can now be opened by specifing their name as the first
243 argument. This means that on a properly configured desktop, double
244 clicking on an icon will open the file.
246 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
247 via using an "intelligent" application assistant dialog.
251 - The new "cairo" output driver supports output in PostScript, PDF,
252 and SVG formats. Its functionality is a superset of that of the
253 "postscript" driver, which has been removed. You must have Cairo
254 and Pango installed to build the "cairo" driver.
256 - Charts are now produced with Cairo and Pango, instead of libplot.
257 Without them, the new graphing features will not work. If you do
258 not have Cairo and Pango installed, you must run `configure' with
261 - The plain text output driver now properly supports multibyte UTF-8
262 characters, including double-width characters and combining
265 - Output to OpenDocument format is now supported.
267 - The HTML output is much improved.
269 * The "pspp" program has a new option --batch (or -b) that selects
270 "batch" syntax mode. In previous versions of PSPP this syntax mode
271 was the default. Now a new "auto" syntax mode is the default. In
272 "auto" mode, PSPP interprets most syntax files correctly regardless
273 of their intended syntax mode.
275 See the "Syntax Variants" section in the PSPP manual for more
278 * The "pspp" program has a new option --syntax-encoding that
279 specifies the encoding for syntax files listed on the command line,
280 as well as the default encoding for syntax files included with
281 INCLUDE or INSERT. The default is to accept the system locale
282 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
283 one the system file uses.
285 See the documentation for the INSERT command in the PSPP manual for
288 * Text data files that PRINT and WRITE creates now use the system
289 native line ends by default (CRLF on Windows, LF only elsewhere).
290 Use the new ENDS subcommand on FILE HANDLE to override the default.
292 * A new Perl module allows Perl programs to read and write PSPP
295 * A tutorial chapter has been added to the user manual.
297 Changes from 0.6.1 to 0.6.2:
301 - Dutch, thanks to Harry Thijssen.
303 - Brazilian Portuguese, thanks to Michel Boaventura.
305 Thanks for translations are also due to the coordinators at
306 translationproject.org.
308 * Statistical bug fixes:
310 - REGRESSION: Report correct standard error of the estimate (bug
313 - T-TEST: Report correct significance of paired sample T-test in
314 the common case (bug #26936) and corner cases. Thanks to Mike
315 Griffiths and Matej Cepl for reporting these bugs.
317 * Build fixes and changes:
319 - Fix build with GTK+ 2.17.4 and later.
321 - Make running "make" after running "configure" with different
322 settings reliably rebuild version.c.
324 - Cygwin and MinGW build fixes.
326 - Fixes for building with recent gnulib.
328 - The Makefile now honors two new variables, PSPP_LDFLAGS and
329 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
330 binaries, respectively. This makes building easier for some
333 - Fixes for "configure --enable-relocatable" (bug #25508).
335 * Data file bug fixes and changes:
337 - Fix reading text data files that contain a mix of white space
338 and commas. Now "a ,b" is treated as two fields containing "a"
339 and "b"; previously it was treated as three, with an empty field
342 - Fix writing corrupted .sav files on Windows.
344 - Fix writing variable labels longer than 252 bytes to save files.
345 Thanks to Robert Westlund for reporting this bug.
347 - Fix writing corrupted .por files (bug #26034).
349 - Fix reading .por files whose initial lines are not padded out
350 with spaces as expected.
352 - PSPP will no longer issue warnings about some .sav file records
353 or values that it does not understand. These warnings were
354 harmless, but needlessly alarmed some users.
356 - Fix crash reading empty string fields from PostgreSQL databases.
358 * Bug fixes that affect PSPP and PSPPIRE:
360 - Users may now control precision of output statistics. Instead
361 of hard coding the width and decimals of output numbers, respect
362 the default format in most instances. Counts are now normally
363 displayed with the format of the weight variable, if any.
365 - Fix crash when an INSERT command specifies the name of a file
366 that does not exist (bug #24569).
368 - Fix crash when CROSSTABS specifies a long-string variable (bugs
371 - Fix crash drawing pie charts with many segments.
373 - Fix crash when NUMERIC specifies an invalid format.
375 * PSPPIRE bug fixes and changes:
377 - On Windows, write the output file to the user's home directory
378 instead of the current directory, to better match user
381 - Some data editor fixes.
385 - Fix typo in BINOMIAL section of user manual (bug #25892).
387 Changes from 0.6.0 to 0.6.1:
389 * Statistical bug fixes:
391 - Report correct standardized regression coefficients in linear
392 regression output (bug #23567).
394 * Bug fixes that affect PSPP and PSPPIRE:
396 - Avoid crash with pie charts (bug #24014).
398 - Don't append % to count totals (bug #24003).
400 - Don't crash on bad input (bug #24031).
402 - Don't crash if "end data." is not left aligned (bug #24115).
404 - Change default workspace value to 64 MB, to avoid unnecessary
405 disk accesses on modern machines.
409 - Add ".sav" or ".por" suffix to filename when saving with Save_As
412 - Make it possible to reopen the output window on Windows (bug
415 - A POSIX regular expression library is now included and used
416 automatically if the host does not have one or has one that is
419 * Build fixes and changes:
421 - Work around bug in GSL that prevented build with recent GCC
422 versions without manually adding -fgnu89-inline to CFLAGS.
424 - Also warn about missing prerequisites as we encounter them (bug
427 - Distribute necessary files to allow users working from the
428 distributed tarball to configure with --enable-gui-tools.
430 - Append $(EXEEXT_FOR_BUILD) to output file name when building
431 q2c, fixing build problems on Windows.
433 - GSL 1.8 or later is now required.
435 - Build errors with --enable-relocatable were fixed.
437 * The German translations were removed, since native German speakers
438 found them too poor to be useful.
440 Changes from 0.4.0 to 0.6.0:
442 * The PSPP license is now version 3 or later of the GNU General
443 Public License. Previously, it was version 2 or later.
445 * PSPP now has a graphical interface, called PSPPIRE. This
446 interface allows you to enter data and variable definitions
447 interactively. Commands may be executed in syntax form, or by
448 using the interactive dialog boxes available from the dropdown
451 * A few sample syntax files are now included in the `examples'
454 * Numerous major and minor bugs have been fixed.
458 * The INSTALL file now reflects the details of how to install
459 PSPP. It is a tailored version of the generic installation
460 instructions, instead of a verbatim copy.
462 * iconv, which is ordinarily installed as part of a Unix-like
463 system, is now required. If you don't have it already, you can
464 install GNU libiconv (http://www.gnu.org/software/libiconv/).
466 * libxml2 and zlib are new optional dependencies. They are
467 required to use PSPP's support for reading Gnumeric files.
469 Statistical procedure changes:
471 * REGRESSION is a new procedure for fitting linear models to data
472 via least-squares estimation.
474 * NPAR TESTS is a new procedure for non-parametric tests. In this
475 release, it supports binomial and chi-square tests.
477 * RANK is a new procedure to rank variables. It supports numerous
480 * FREQUENCIES can now output histograms and pie charts. These
481 features were present in earlier releases, but not documented.
483 User interface changes:
485 * In many situations where PSPP once terminated with a fatal
486 error, PSPP now recovers and continues execution.
488 * PSPP is now able to start up and run even if it cannot find its
491 * Journaling of interactive commands to a disk file is now
492 implemented. By default, journaling is enabled, to a file named
493 `pspp.jnl' in the current directory. SET JOURNAL may be used to
496 * The use of `+' between syntax file names on the command line to
497 prevent the dictionary from being cleared between their
498 executions is no longer supported. All syntax files are now
499 executed as if `+' had been specified.
501 * The -d/--define and -u/--undef command line options are no
502 longer supported. Instead, use /usr/bin/env or shell primitives
503 to define or clear environment variables before invoking PSPP.
505 * If a syntax file named named `rc' is found in a configuration
506 directory (such as $HOME/.pspp), it is executed before any
507 syntax file specified on the command line. The -r or
508 --no-statrc command line option may be used to disable this
513 * Output configuration options have changed. Please refer to the
514 manual for a full description of the available options.
516 In consequence, you will need to reinstall your "devices" file.
517 "make install" will do this for you.
519 * Most error messages are now written to PSPP output files by
520 default. SET ERROR can be used to disable this behavior.
522 * When invoked interactively, PSPP now by default produces output
523 on the terminal, piping it through the "more" program.
524 Previously, by default output was written only to file
525 pspp.list. On most terminals, the page length used for output
526 automatically adapts to the terminal size, even if the terminal
531 - This driver now supports charts in output. Charts are written
532 as separate files that the main output file refers to. By
533 default, charts are written in PNG format to files named
534 pspp-1.png, pspp-2.png, and so on.
536 - Configurations are provided that use VT100 (and xterm)
537 line-drawing characters in tables. The option "-o list-vt100"
538 requests use of this device for output to pspp.list.
542 - The default paper size is now determined using the PAPERSIZE
543 environment variable, or the LC_PAPER locale category on
544 systems that support it. If these are not set, the default is
545 now A4, instead of US letter. To make US letter the default,
546 set PAPERSIZE to "letter" in your environment.
548 - Font metrics are now read from AFM files, instead of
549 Groff-format metrics files. PostScript fonts can now be
552 In consequence, you will need to install an AFM file for each
553 font used in PostScript output. "make install" will install
554 AFM files for the standard PostScript fonts, including the
555 ones that the PostScript driver uses by default.
557 - Standard paper sizes no longer need to be specified through a
558 configuration file. The "papersize" configuration file is no
559 longer needed, or supported.
561 - The PostScript prologue is no longer obtained from the
562 "ps-prologue" configuration file. This configuration file is
563 no longer needed, or supported.
567 - The HTML prologue is no longer obtained from the
568 "html-prologue" configuration file. This configuration file
569 is no longer needed, or supported.
571 Command language changes:
573 * The following commands are new:
575 - GET DATA, which currently supports reading Gnumeric files and
576 text data files. It will be extended later to read other
577 types of foreign data.
579 - CD, to change the current directory.
581 - INSERT, to execute a syntax file.
583 - DELETE VARIABLES, to remove variables from the active file
586 - ADD DOCUMENT, to add text to active file documents.
588 - CLOSE FILE HANDLE (a PSPP extension; see below).
590 - XEXPORT, a PSPP extension that is a transformation equivalent
593 * The following functions for transformation expressions are new:
595 - DATEDIFF, for computing the difference of two dates.
597 - DATESUM, for advancing a date by a specified duration.
599 - VALUELABEL, to obtain the value label for a value.
601 * PSPP now supports very long string variables (over 255 bytes
604 * MATCH FILES now supports the FIRST and LAST subcommands.
606 * Previous versions of PSPP prohibited using commands to both read and
607 write a single file at the same time. Now, PSPP allows this, and
608 the new version of the file atomically replaces the old version.
610 * The following commands are no longer available. They will be
611 re-implemented in a later release:
613 - CLEAR TRANSFORMATIONS
619 * The PROCESS IF command, which was deprecated, has been removed.
620 You may replace any usage of it by SELECT IF following
621 TEMPORARY, which has the same effect.
623 * The output format for variables created by VECTOR may now be
624 specified as part of the VECTOR syntax.
626 "Scratch files", a new PSPP extension:
628 A scratch file, like a system file, consists of a dictionary and
629 any number of cases. Small scratch files are stored in memory;
630 one that grows too large is written to disk. By default, any file
631 handle whose name begins with # is assumed to refer to a scratch
634 Scratch files can be used just about anywhere a system or portable
635 file can be used. Also, portable files are now allowed in most
636 places that system files were allowed in previous PSPP version.
638 A new CLOSE FILE HANDLE command allows the storage associated with
639 scratch files to be freed. It also allows file handles to be
640 reassigned to new files.
642 For more information on scratch files, refer to the "File Handles"
643 section in the PSPP manual. For specifics of what commands now
644 allow what kinds of files to be specified, refer to the
645 documentation on those particular commands.
649 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
650 translation, are now supported. Use FILE HANDLE to specify the
651 format of these files.
653 * Little-endian, big-endian, and VAX-endian formats are now
654 supported for integer binary formats when reading and writing
655 data files. The new RIB and WIB subcommands on the SET command
656 control endianness of integer data. The default is the host's
659 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
660 floating point binary formats when reading and writing data
661 files. The new RRB and WRB subcommands on the SET command
662 control the floating point format. The default is the host's
663 native floating point format.
665 * DATA LIST now supports the SKIP subcommand, to skip records at
666 the beginning of a file. For compatibility, DATA LIST now
667 treats N format as F format for FREE and LIST format input.
669 * The SAVE and XSAVE commands now support the UNSELECTED,
670 PERMISSIONS, NAMES, and MAP subcommands.
672 * The EXPORT command has been re-implemented to obtain better
673 results. Support for the UNSELECTED, DIGITS, and TYPE
674 subcommands has been added.
676 * For compatibility, PRINT now inserts a space at the beginning of
677 every output line, even lines that would otherwise be blank,
678 when OUTFILE is specified. (The behavior of WRITE is
681 * For compatibility, PRINT EJECT now inserts the digit `1' at the
682 beginning of each line that should begin a new page.
684 * For compatibility, WRITE now outputs the system-missing value as
685 a field filled with spaces. Binary formats are an exception.
686 (The behavior of PRINT is unchanged.)
690 * Input and output format descriptions have been rewritten. They
691 now precisely describe what is accepted on input and written on
694 * The descriptions of the PSPP system and portable file formats
695 have been extensively revised and improved.
697 For developers, the build system now requires Autoconf 2.60 and
700 Changes from 0.3.0 to 0.4.0:
702 Changes in build dependencies:
704 * The GNU Scientific Library (libgsl), version 1.6 or later, is
707 * libplot from GNU plotutils is optional. Without it, the new
708 graphing features will not work. If you do not have it
709 installed, you must run `configure' with --without-libplot.
711 * libgmp2 is no longer a dependency.
713 Newly implemented commands and statistical features:
715 * EXAMINE, including its graphing features.
717 * FREQUENCIES now supports percentiles.
725 * SORT CASES now sorts stably, that is, two cases with equal sort
726 criteria will be in the same relative order before and after the
729 * T-TEST (re-written).
731 * DATE and USE. These commands are parsed but otherwise ignored,
732 to enhance compatibility with certain command files that invoke
735 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
736 currently have no effect on PSPP output, but their values are
737 written to and read from system files and thus may affect
738 third-party software.
740 * SET EPOCH implemented.
742 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
745 * FILE HANDLE now supports custom tab widths.
747 Long variable names (and other identifiers) are now supported. Up
748 to the first 64 bytes of each identifier is significant. PSPP now
749 reads and writes system files compatible with SPSS version 12.
751 New --algorithm and --syntax command line options allow
752 SPSS-compatible or enhanced modes to be selected.
754 Support for transformation expressions has been rewritten and
755 significantly improved. Refer to the manual for details.
757 Calculation of moments (mean, standard deviation, kurtosis,
758 skewness) has been rewritten and should now be more accurate. In
759 --algorithm=enhanced mode moments may be more accurate than SPSS in
762 Numerous bugs have been fixed, too many to mention here. Many new
763 tests have been added, leading to the discovery and fixing of many
766 The ASCII output driver can now squeeze multiple blank lines into
769 Much of the code has been rewritten and refactored. It is now much
772 The FILE TYPE and REPEATING DATA commands have been disabled for
773 this release because their implementations were deemed too buggy to
774 be useful. They will be fixed and replaced in a future release.
776 New pspp-mode for Emacs (in pspp-mode.el).
778 Added rudimentary command-line completion for interactive input.
780 lib/julcal and lib/dcdflib are no longer used, so they have been
783 For developers, the build system now requires Autoconf 2.58 and
784 Automake 1.7. The included gettext has been updated to version
787 Some reports state that Texinfo 4.8, the latest version, may be
788 necessary to successfully format the documentation on some systems.
790 Version 0.3.0 changes since 0.2.3:
794 * Using alphanumeric variables in functions under AGGREGATE
797 * Under certain circumstances, the final case would be omitted
798 from the results of an AGGREGATE operation. Fixed.
800 * Undefined behavior was invoked by referencing a freed pointer
801 under certain circumstances. Fixed.
803 * A wrong record size was displayed when paging the active file to
806 * Not having enough temporary space for sorting caused a core
809 * Syntax errors in function descriptions on AGGREGATE caused core
812 * A null pointer was dereferenced, causing a core dump, when
813 PERCENTILES was specified on FREQUENCIES. This fixes the
814 problem, but PSPP still doesn't calculate percentiles.
816 * SORT always sorted in ascending order. Fixed.
818 * Some minor memory leaks in the expression parser were removed.
820 * Many assertions fixed for strict ANSI C compliance.
824 * SET ECHO ON now implemented, but turned off by default.
826 * PRINT specifier supported on END REPEAT.
830 * System libgmp2 library is used if installed instead of
831 unconditionally using the included libgmp2 subset.
833 * Extensive code cleanup, which continues.
835 * Added CORRELATIONS command parser, but not implemented.
837 Version 0.2.3 changes since 0.2.2:
841 * SPLIT FILE with a string variable caused a core dump. Fixed.
843 * Nested INCLUDEs didn't work. Fixed.
845 * The MATCH FILES procedure set the values of variables not present
846 to 0. It should have been SYSMIS. This is now fixed.
848 * The REMARK command was too aggressive about skipping lines. It
849 didn't like being the last command in a file.
851 * Comment parsing wasn't consistent with the rest of the code in its
852 idea of where one command ends and another starts. This meant
853 that sometimes commands would be mysteriously ignored. Thanks to
854 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
856 * The TABLE subcommand on MATCH FILES worked only erratically at
857 best. This fixes it. Thanks to Dr. Dirk Melcher
858 <BZN-mdksh@t-online.de> for reporting this bug.
860 * VARIABLE LABELS rejected a slash before the first variable
861 specification, contradicting the documentation. Thanks to Walter
862 M. Gray <graywm@northernc.on.ca> for reporting this bug.
864 * Because of an incorrect optimization in memory allocation,
865 CROSSTABS sometimes segfaulted when asked to output multiple
866 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
869 * CROSSTABS didn't display value labels for column and row
870 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
873 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
874 <BZN-mdksh@t-online.de> for reporting this bug.

890 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
893 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
894 <BZN-mdksh@t-online.de> for reporting this bug.
896 * MATCH FILES corrupted memory and dumped core on some syntax
899 * MATCH FILES should set numeric values not available to the
900 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
901 <BZN-mdksh@t-online.de> for reporting this bug.
903 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
904 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.

909 Hankin <hankin@rogue.consultco.com> for pointing this out.
911 * The SAVE procedure didn't save long string variables properly.
912 Fixed by this patch. Thanks to Hankin
913 <hankin@rogue.consultco.com> for this patch.
915 * Minor documentation fixes for MATCH FILES.

925 * Fix LIST problems with very long variables. Thanks to Hankin
926 <hankin@dunno.com> for this bug report.
928 * Fix problems with some string format specifiers.
930 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
931 <BZN-mdksh@t-online.de> for reporting this bug.
933 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
934 Hankin <hankin@dunno.com> again on this one.
936 * Sometimes you may encounter a PSPP script that has to be
937 interpreted in interactive mode. Now you can use the -i flag to
940 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
941 `unused variable' warnings under gcc 2.7.2.3, fixing this will
946 * The files in gmp need the internationalization directory in
947 their include path. Thanks to OKUJI Yoshinori
