5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * SPSS/PC+ system files are now supported on GET and other commands
10 that read SPSS system files. The pspp-convert program can now read
11 SPSS/PC+ system files. Writing the obsolete SPSS/PC+ system file
12 format is not supported.
14 * SYSFILE INFO can now read SPSS/PC+ system files and SPSS portable
17 * FREQUENCIES: A bug was fixed where an assertion failure occured
18 when an empty dataset was presented.
20 * The GRAPH command is now available. Initially it supports
21 scatterplots and histograms.
23 Changes from 0.8.3 to 0.8.4:
25 * Formatting of SYSFILE INFO output was made easier to read.
27 * Bug fixes, including the following notable ones:
29 - FREQUENCIES works properly for string variables. (This bug was
32 - CROSSTABS now correctly computes all of the measures that it
33 offers. Some measures have been removed because they were not
36 - The NPAR TESTS calculation of significance for the RUNS
37 subcommand has been corrected.
39 - Planned comparisons in ONEWAY ANOVA now correctly handle negative
42 - Conformance fixes to Open Document output format.
44 Changes from 0.8.2 to 0.8.3:
46 * Independent T-Tests displayed the standard error of the difference
47 and the confidence interval for the unequal variances case, where
48 the equal variances case should have been. This has been fixed.
50 * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
51 intervals for the coefficients to be printed.
53 * When DESCRIPTIVES calculates Z scores, it now omits cases filtered
54 by the current FILTER settings.
56 * PSPPIRE graphical user interface improvements:
58 - Dialog boxes with source variable lists can now choose the sort
59 order; right click and select from the popup menu.
61 - File|Open now allows an encoding to be selected for opening
64 - File|Display Data File Information|External File... now allows an
65 encoding to be selected.
67 - A problem with the Means dialog has been resolved (bug #41433).
69 - Several problems related to the input of spreadsheets have been
70 fixed (bug #41657, #41620
72 * System file related improvements:
74 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
75 pick an encoding for reading a system file that does not identify
78 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
79 character encoding of string data in the system file.
81 - Variable labels over 255 bytes long are now accepted without
82 truncation (bug #41863).
84 - System files that contain duplicate variable names may now be
85 read successfully (bug #41475).
87 Changes from 0.8.1 to 0.8.2:
89 * Charts are now rendered with colours from the Tango palette instead
90 of fully saturated primaries.
92 * Support for new system file variants:
94 - PSPP can now read and write ZCOMPRESSED system files, which
95 compress data much more effectively than older "compressed"
96 files. (The older format is still supported.)
98 - PSPP can now decrypt encrypted system files, using the new
99 pspp-convert utility. The encrypted system file format is
100 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
101 do not directly read or write this format.
103 * Missing values for long string variables are now read from and
104 written to system files in an SPSS-compatible fashion.
106 (Earlier versions of PSPP that supported missing values for long
107 string variables wrote them to system files in an SPSS-incompatible
108 way. To fix the problem, read the system file with this version of
109 PSPP and then save a new copy of it.)
111 * pspp-convert, a new standalone utility for converting SPSS system
112 and portable files to other formats, is now included. The initial
113 version supports comma-separated value files as output format.
114 pspp-convert can also decrypt encrypted system files.
118 - zlib is now a required dependency. (Previously it was optional.)
120 Changes from 0.8.0 to 0.8.1:
126 * Changes to existing commands:
128 - CROSSTABS: The requirement that one expected count must be less than five
129 before Fishers Exact Test will be reported has been removed.
131 * PSPPIRE graphical user interface improvements:
133 - A new set of icons has been contributed.
135 - Syntax windows now parse syntax in "auto" mode, which in practice
136 should mean that both "batch" and "interactive" syntax now works,
137 instead of just "interactive" syntax.
139 - The variable pane of data windows now include a Role column.
143 - System files written by IBM SPSS 21 are now read without warnings.
145 - System files written by "VOXCO INTERVIEWER 4.3" are now read
148 - PSPPIRE should now more gracefully handle syntax files that contain
151 Changes from 0.6.2 to 0.8.0:
157 - DATAFILE ATTRIBUTES
164 - LOGISTIC REGRESSION
168 - PRESERVE and RESTORE
172 - SAVE TRANSLATE to CSV and tab-delimited files
174 - VARIABLE ATTRIBUTES
176 * Changes to existing commands:
178 - AUTORECODE has a new GROUP subcommand.
180 - CROSSTABS has been re-implemented to fix numerous bugs.
182 - EXAMINE: /MISSING=LISTWISE is now the default.
184 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
185 contains an INCLUDE or INSERT command, substitutions are not
186 applied to the included file.
188 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
190 - HOST has been updated to use more modern syntax.
192 - Most commands that work with data files now support a new
195 - MISSING VALUES can now assign missing values to long string
198 - ONEWAY: the POSTHOC subcommand is now implemented.
200 - The following new subcommands to NPAR TESTS have been implemented:
201 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
202 MCNEMAR, SIGN, WILCOXON, and RUNS
204 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
205 DPROMPT subcommands. The defaults are now fixed values.
207 - SHOW now has a JOURNAL subcommand, to show the location of the
210 - VALUE LABELS can now assign value labels to long string
213 * Other language changes:
215 - The new DATASET commands replace the "scratch file" PSPP
216 extension, which is no longer supported.
218 - Strings may now include arbitrary Unicode code points specified
219 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
220 code point U+1D11E, the musical G clef character, may be
221 expressed as U'1D11E'.
223 See the "Tokens" section in the PSPP manual for more information.
225 - In previous versions of PSPP, in a string expressed in
226 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
227 bytes in the locale encoding. In this version of PSPP, X'hh'
228 syntax always expresses bytes in UTF-8 encoding.
230 See the "Tokens" section in the PSPP manual for more information.
232 * PSPPIRE graphical user interface improvements:
234 - Added support for non-ASCII characters in strings, labels and
237 - A "Split Window" function is available, which makes it easier to
238 see different parts of a large data file.
240 - Data files can now be opened by specifing their name as the first
241 argument. This means that on a properly configured desktop, double
242 clicking on an icon will open the file.
244 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
245 via using an "intelligent" application assistant dialog.
249 - The new "cairo" output driver supports output in PostScript, PDF,
250 and SVG formats. Its functionality is a superset of that of the
251 "postscript" driver, which has been removed. You must have Cairo
252 and Pango installed to build the "cairo" driver.
254 - Charts are now produced with Cairo and Pango, instead of libplot.
255 Without them, the new graphing features will not work. If you do
256 not have Cairo and Pango installed, you must run `configure' with
259 - The plain text output driver now properly supports multibyte UTF-8
260 characters, including double-width characters and combining
263 - Output to OpenDocument format is now supported.
265 - The HTML output is much improved.
267 * The "pspp" program has a new option --batch (or -b) that selects
268 "batch" syntax mode. In previous versions of PSPP this syntax mode
269 was the default. Now a new "auto" syntax mode is the default. In
270 "auto" mode, PSPP interprets most syntax files correctly regardless
271 of their intended syntax mode.
273 See the "Syntax Variants" section in the PSPP manual for more
276 * The "pspp" program has a new option --syntax-encoding that
277 specifies the encoding for syntax files listed on the command line,
278 as well as the default encoding for syntax files included with
279 INCLUDE or INSERT. The default is to accept the system locale
280 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
281 one the system file uses.
283 See the documentation for the INSERT command in the PSPP manual for
286 * Text data files that PRINT and WRITE creates now use the system
287 native line ends by default (CRLF on Windows, LF only elsewhere).
288 Use the new ENDS subcommand on FILE HANDLE to override the default.
290 * A new Perl module allows Perl programs to read and write PSPP
293 * A tutorial chapter has been added to the user manual.
295 Changes from 0.6.1 to 0.6.2:
299 - Dutch, thanks to Harry Thijssen.
301 - Brazilian Portuguese, thanks to Michel Boaventura.
303 Thanks for translations are also due to the coordinators at
304 translationproject.org.
306 * Statistical bug fixes:
308 - REGRESSION: Report correct standard error of the estimate (bug
311 - T-TEST: Report correct significance of paired sample T-test in
312 the common case (bug #26936) and corner cases. Thanks to Mike
313 Griffiths and Matej Cepl for reporting these bugs.
315 * Build fixes and changes:
317 - Fix build with GTK+ 2.17.4 and later.
319 - Make running "make" after running "configure" with different
320 settings reliably rebuild version.c.
322 - Cygwin and MinGW build fixes.
324 - Fixes for building with recent gnulib.
326 - The Makefile now honors two new variables, PSPP_LDFLAGS and
327 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
328 binaries, respectively. This makes building easier for some
331 - Fixes for "configure --enable-relocatable" (bug #25508).
333 * Data file bug fixes and changes:
335 - Fix reading text data files that contain a mix of white space
336 and commas. Now "a ,b" is treated as two fields containing "a"
337 and "b"; previously it was treated as three, with an empty field
340 - Fix writing corrupted .sav files on Windows.
342 - Fix writing variable labels longer than 252 bytes to save files.
343 Thanks to Robert Westlund for reporting this bug.
345 - Fix writing corrupted .por files (bug #26034).
347 - Fix reading .por files whose initial lines are not padded out
348 with spaces as expected.
350 - PSPP will no longer issue warnings about some .sav file records
351 or values that it does not understand. These warnings were
352 harmless, but needlessly alarmed some users.
354 - Fix crash reading empty string fields from PostgreSQL databases.
356 * Bug fixes that affect PSPP and PSPPIRE:
358 - Users may now control precision of output statistics. Instead
359 of hard coding the width and decimals of output numbers, respect
360 the default format in most instances. Counts are now normally
361 displayed with the format of the weight variable, if any.
363 - Fix crash when an INSERT command specifies the name of a file
364 that does not exist (bug #24569).
366 - Fix crash when CROSSTABS specifies a long-string variable (bugs
369 - Fix crash drawing pie charts with many segments.
371 - Fix crash when NUMERIC specifies an invalid format.
373 * PSPPIRE bug fixes and changes:
375 - On Windows, write the output file to the user's home directory
376 instead of the current directory, to better match user
379 - Some data editor fixes.
383 - Fix typo in BINOMIAL section of user manual (bug #25892).
385 Changes from 0.6.0 to 0.6.1:
387 * Statistical bug fixes:
389 - Report correct standardized regression coefficients in linear
390 regression output (bug #23567).
392 * Bug fixes that affect PSPP and PSPPIRE:
394 - Avoid crash with pie charts (bug #24014).
396 - Don't append % to count totals (bug #24003).
398 - Don't crash on bad input (bug #24031).
400 - Don't crash if "end data." is not left aligned (bug #24115).
402 - Change default workspace value to 64 MB, to avoid unnecessary
403 disk accesses on modern machines.
407 - Add ".sav" or ".por" suffix to filename when saving with Save_As
410 - Make it possible to reopen the output window on Windows (bug
413 - A POSIX regular expression library is now included and used
414 automatically if the host does not have one or has one that is
417 * Build fixes and changes:
419 - Work around bug in GSL that prevented build with recent GCC
420 versions without manually adding -fgnu89-inline to CFLAGS.
422 - Also warn about missing prerequisites as we encounter them (bug
425 - Distribute necessary files to allow users working from the
426 distributed tarball to configure with --enable-gui-tools.
428 - Append $(EXEEXT_FOR_BUILD) to output file name when building
429 q2c, fixing build problems on Windows.
431 - GSL 1.8 or later is now required.
433 - Build errors with --enable-relocatable were fixed.
435 * The German translations were removed, since native German speakers
436 found them too poor to be useful.
438 Changes from 0.4.0 to 0.6.0:
440 * The PSPP license is now version 3 or later of the GNU General
441 Public License. Previously, it was version 2 or later.
443 * PSPP now has a graphical interface, called PSPPIRE. This
444 interface allows you to enter data and variable definitions
445 interactively. Commands may be executed in syntax form, or by
446 using the interactive dialog boxes available from the dropdown
449 * A few sample syntax files are now included in the `examples'
452 * Numerous major and minor bugs have been fixed.
456 * The INSTALL file now reflects the details of how to install
457 PSPP. It is a tailored version of the generic installation
458 instructions, instead of a verbatim copy.
460 * iconv, which is ordinarily installed as part of a Unix-like
461 system, is now required. If you don't have it already, you can
462 install GNU libiconv (http://www.gnu.org/software/libiconv/).
464 * libxml2 and zlib are new optional dependencies. They are
465 required to use PSPP's support for reading Gnumeric files.
467 Statistical procedure changes:
469 * REGRESSION is a new procedure for fitting linear models to data
470 via least-squares estimation.
472 * NPAR TESTS is a new procedure for non-parametric tests. In this
473 release, it supports binomial and chi-square tests.
475 * RANK is a new procedure to rank variables. It supports numerous
478 * FREQUENCIES can now output histograms and pie charts. These
479 features were present in earlier releases, but not documented.
481 User interface changes:
483 * In many situations where PSPP once terminated with a fatal
484 error, PSPP now recovers and continues execution.
486 * PSPP is now able to start up and run even if it cannot find its
489 * Journaling of interactive commands to a disk file is now
490 implemented. By default, journaling is enabled, to a file named
491 `pspp.jnl' in the current directory. SET JOURNAL may be used to
494 * The use of `+' between syntax file names on the command line to
495 prevent the dictionary from being cleared between their
496 executions is no longer supported. All syntax files are now
497 executed as if `+' had been specified.
499 * The -d/--define and -u/--undef command line options are no
500 longer supported. Instead, use /usr/bin/env or shell primitives
501 to define or clear environment variables before invoking PSPP.
503 * If a syntax file named named `rc' is found in a configuration
504 directory (such as $HOME/.pspp), it is executed before any
505 syntax file specified on the command line. The -r or
506 --no-statrc command line option may be used to disable this
511 * Output configuration options have changed. Please refer to the
512 manual for a full description of the available options.
514 In consequence, you will need to reinstall your "devices" file.
515 "make install" will do this for you.
517 * Most error messages are now written to PSPP output files by
518 default. SET ERROR can be used to disable this behavior.
520 * When invoked interactively, PSPP now by default produces output
521 on the terminal, piping it through the "more" program.
522 Previously, by default output was written only to file
523 pspp.list. On most terminals, the page length used for output
524 automatically adapts to the terminal size, even if the terminal
529 - This driver now supports charts in output. Charts are written
530 as separate files that the main output file refers to. By
531 default, charts are written in PNG format to files named
532 pspp-1.png, pspp-2.png, and so on.
534 - Configurations are provided that use VT100 (and xterm)
535 line-drawing characters in tables. The option "-o list-vt100"
536 requests use of this device for output to pspp.list.
540 - The default paper size is now determined using the PAPERSIZE
541 environment variable, or the LC_PAPER locale category on
542 systems that support it. If these are not set, the default is
543 now A4, instead of US letter. To make US letter the default,
544 set PAPERSIZE to "letter" in your environment.
546 - Font metrics are now read from AFM files, instead of
547 Groff-format metrics files. PostScript fonts can now be
550 In consequence, you will need to install an AFM file for each
551 font used in PostScript output. "make install" will install
552 AFM files for the standard PostScript fonts, including the
553 ones that the PostScript driver uses by default.
555 - Standard paper sizes no longer need to be specified through a
556 configuration file. The "papersize" configuration file is no
557 longer needed, or supported.
559 - The PostScript prologue is no longer obtained from the
560 "ps-prologue" configuration file. This configuration file is
561 no longer needed, or supported.
565 - The HTML prologue is no longer obtained from the
566 "html-prologue" configuration file. This configuration file
567 is no longer needed, or supported.
569 Command language changes:
571 * The following commands are new:
573 - GET DATA, which currently supports reading Gnumeric files and
574 text data files. It will be extended later to read other
575 types of foreign data.
577 - CD, to change the current directory.
579 - INSERT, to execute a syntax file.
581 - DELETE VARIABLES, to remove variables from the active file
584 - ADD DOCUMENT, to add text to active file documents.
586 - CLOSE FILE HANDLE (a PSPP extension; see below).
588 - XEXPORT, a PSPP extension that is a transformation equivalent
591 * The following functions for transformation expressions are new:
593 - DATEDIFF, for computing the difference of two dates.
595 - DATESUM, for advancing a date by a specified duration.
597 - VALUELABEL, to obtain the value label for a value.
599 * PSPP now supports very long string variables (over 255 bytes
602 * MATCH FILES now supports the FIRST and LAST subcommands.
604 * Previous versions of PSPP prohibited using commands to both read and
605 write a single file at the same time. Now, PSPP allows this, and
606 the new version of the file atomically replaces the old version.
608 * The following commands are no longer available. They will be
609 re-implemented in a later release:
611 - CLEAR TRANSFORMATIONS
617 * The PROCESS IF command, which was deprecated, has been removed.
618 You may replace any usage of it by SELECT IF following
619 TEMPORARY, which has the same effect.
621 * The output format for variables created by VECTOR may now be
622 specified as part of the VECTOR syntax.
624 "Scratch files", a new PSPP extension:
626 A scratch file, like a system file, consists of a dictionary and
627 any number of cases. Small scratch files are stored in memory;
628 one that grows too large is written to disk. By default, any file
629 handle whose name begins with # is assumed to refer to a scratch
632 Scratch files can be used just about anywhere a system or portable
633 file can be used. Also, portable files are now allowed in most
634 places that system files were allowed in previous PSPP version.
636 A new CLOSE FILE HANDLE command allows the storage associated with
637 scratch files to be freed. It also allows file handles to be
638 reassigned to new files.
640 For more information on scratch files, refer to the "File Handles"
641 section in the PSPP manual. For specifics of what commands now
642 allow what kinds of files to be specified, refer to the
643 documentation on those particular commands.
647 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
648 translation, are now supported. Use FILE HANDLE to specify the
649 format of these files.
651 * Little-endian, big-endian, and VAX-endian formats are now
652 supported for integer binary formats when reading and writing
653 data files. The new RIB and WIB subcommands on the SET command
654 control endianness of integer data. The default is the host's
657 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
658 floating point binary formats when reading and writing data
659 files. The new RRB and WRB subcommands on the SET command
660 control the floating point format. The default is the host's
661 native floating point format.
663 * DATA LIST now supports the SKIP subcommand, to skip records at
664 the beginning of a file. For compatibility, DATA LIST now
665 treats N format as F format for FREE and LIST format input.
667 * The SAVE and XSAVE commands now support the UNSELECTED,
668 PERMISSIONS, NAMES, and MAP subcommands.
670 * The EXPORT command has been re-implemented to obtain better
671 results. Support for the UNSELECTED, DIGITS, and TYPE
672 subcommands has been added.
674 * For compatibility, PRINT now inserts a space at the beginning of
675 every output line, even lines that would otherwise be blank,
676 when OUTFILE is specified. (The behavior of WRITE is
679 * For compatibility, PRINT EJECT now inserts the digit `1' at the
680 beginning of each line that should begin a new page.
682 * For compatibility, WRITE now outputs the system-missing value as
683 a field filled with spaces. Binary formats are an exception.
684 (The behavior of PRINT is unchanged.)
688 * Input and output format descriptions have been rewritten. They
689 now precisely describe what is accepted on input and written on
692 * The descriptions of the PSPP system and portable file formats
693 have been extensively revised and improved.
695 For developers, the build system now requires Autoconf 2.60 and
698 Changes from 0.3.0 to 0.4.0:
700 Changes in build dependencies:
702 * The GNU Scientific Library (libgsl), version 1.6 or later, is
705 * libplot from GNU plotutils is optional. Without it, the new
706 graphing features will not work. If you do not have it
707 installed, you must run `configure' with --without-libplot.
709 * libgmp2 is no longer a dependency.
711 Newly implemented commands and statistical features:
713 * EXAMINE, including its graphing features.
715 * FREQUENCIES now supports percentiles.
723 * SORT CASES now sorts stably, that is, two cases with equal sort
724 criteria will be in the same relative order before and after the
727 * T-TEST (re-written).
729 * DATE and USE. These commands are parsed but otherwise ignored,
730 to enhance compatibility with certain command files that invoke
733 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
734 currently have no effect on PSPP output, but their values are
735 written to and read from system files and thus may affect
736 third-party software.
738 * SET EPOCH implemented.
740 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
743 * FILE HANDLE now supports custom tab widths.
745 Long variable names (and other identifiers) are now supported. Up
746 to the first 64 bytes of each identifier is significant. PSPP now
747 reads and writes system files compatible with SPSS version 12.
749 New --algorithm and --syntax command line options allow
750 SPSS-compatible or enhanced modes to be selected.
752 Support for transformation expressions has been rewritten and
753 significantly improved. Refer to the manual for details.
755 Calculation of moments (mean, standard deviation, kurtosis,
756 skewness) has been rewritten and should now be more accurate. In
757 --algorithm=enhanced mode moments may be more accurate than SPSS in
760 Numerous bugs have been fixed, too many to mention here. Many new
761 tests have been added, leading to the discovery and fixing of many
764 The ASCII output driver can now squeeze multiple blank lines into
767 Much of the code has been rewritten and refactored. It is now much
770 The FILE TYPE and REPEATING DATA commands have been disabled for
771 this release because their implementations were deemed too buggy to
772 be useful. They will be fixed and replaced in a future release.
774 New pspp-mode for Emacs (in pspp-mode.el).
776 Added rudimentary command-line completion for interactive input.
778 lib/julcal and lib/dcdflib are no longer used, so they have been
781 For developers, the build system now requires Autoconf 2.58 and
782 Automake 1.7. The included gettext has been updated to version
785 Some reports state that Texinfo 4.8, the latest version, may be
786 necessary to successfully format the documentation on some systems.
788 Version 0.3.0 changes since 0.2.3:
792 * Using alphanumeric variables in functions under AGGREGATE
795 * Under certain circumstances, the final case would be omitted
796 from the results of an AGGREGATE operation. Fixed.
798 * Undefined behavior was invoked by referencing a freed pointer
799 under certain circumstances. Fixed.
801 * A wrong record size was displayed when paging the active file to
804 * Not having enough temporary space for sorting caused a core
807 * Syntax errors in function descriptions on AGGREGATE caused core
810 * A null pointer was dereferenced, causing a core dump, when
811 PERCENTILES was specified on FREQUENCIES. This fixes the
812 problem, but PSPP still doesn't calculate percentiles.
814 * SORT always sorted in ascending order. Fixed.
816 * Some minor memory leaks in the expression parser were removed.
818 * Many assertions fixed for strict ANSI C compliance.
822 * SET ECHO ON now implemented, but turned off by default.
824 * PRINT specifier supported on END REPEAT.
828 * System libgmp2 library is used if installed instead of
829 unconditionally using the included libgmp2 subset.
831 * Extensive code cleanup, which continues.
833 * Added CORRELATIONS command parser, but not implemented.
835 Version 0.2.3 changes since 0.2.2:
839 * SPLIT FILE with a string variable caused a core dump. Fixed.
841 * Nested INCLUDEs didn't work. Fixed.
843 * The MATCH FILES procedure set the values of variables not present
844 to 0. It should have been SYSMIS. This is now fixed.
846 * The REMARK command was too aggressive about skipping lines. It
847 didn't like being the last command in a file.
849 * Comment parsing wasn't consistent with the rest of the code in its
850 idea of where one command ends and another starts. This meant
851 that sometimes commands would be mysteriously ignored. Thanks to
852 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
854 * The TABLE subcommand on MATCH FILES worked only erratically at
855 best. This fixes it. Thanks to Dr. Dirk Melcher
856 <BZN-mdksh@t-online.de> for reporting this bug.
858 * VARIABLE LABELS rejected a slash before the first variable
859 specification, contradicting the documentation. Thanks to Walter
860 M. Gray <graywm@northernc.on.ca> for reporting this bug.
862 * Because of an incorrect optimization in memory allocation,
863 CROSSTABS sometimes segfaulted when asked to output multiple
864 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
867 * CROSSTABS didn't display value labels for column and row
868 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
871 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
872 <BZN-mdksh@t-online.de> for reporting this bug.

891 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
892 <BZN-mdksh@t-online.de> for reporting this bug.
894 * MATCH FILES corrupted memory and dumped core on some syntax
897 * MATCH FILES should set numeric values not available to the
898 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
899 <BZN-mdksh@t-online.de> for reporting this bug.
901 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
902 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
906 * Some systems didn't like the way open_file was coded. Thanks to
907 Hankin <hankin@rogue.consultco.com> for pointing this out.
909 * The SAVE procedure didn't save long string variables properly.
910 Fixed by this patch. Thanks to Hankin
911 <hankin@rogue.consultco.com> for this patch.
913 * Minor documentation fixes for MATCH FILES.
915 Version 0.2.2 changes since 0.2.1:
919 * Fix behavior of PRINT SPACE for negative arguments.
921 * Fix reading some unusual system files.
923 * Fix LIST problems with very long variables. Thanks to Hankin
924 <hankin@dunno.com> for this bug report.
926 * Fix problems with some string format specifiers.
928 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
929 <BZN-mdksh@t-online.de> for reporting this bug.

932 Hankin <hankin@dunno.com> again on this one.
934 * Sometimes you may encounter a PSPP script that has to be
935 interpreted in interactive mode. Now you can use the -i flag to
938 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
939 `unused variable' warnings under gcc 2.7.2.3, fixing this will
