5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * FREQUENCIES: A bug was fixed where an assertion failure occured
10 when an empty dataset was presented.
12 * The GRAPH command is now available. Initially it supports
13 scatterplots and histograms.
15 Changes from 0.8.3 to 0.8.4:
17 * Formatting of SYSFILE INFO output was made easier to read.
19 * Bug fixes, including the following notable ones:
21 - FREQUENCIES works properly for string variables. (This bug was
24 - CROSSTABS now correctly computes all of the measures that it
25 offers. Some measures have been removed because they were not
28 - The NPAR TESTS calculation of significance for the RUNS
29 subcommand has been corrected.
31 - Planned comparisons in ONEWAY ANOVA now correctly handle negative
34 - Conformance fixes to Open Document output format.
36 Changes from 0.8.2 to 0.8.3:
38 * Independent T-Tests displayed the standard error of the difference
39 and the confidence interval for the unequal variances case, where
40 the equal variances case should have been. This has been fixed.
42 * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
43 intervals for the coefficients to be printed.
45 * When DESCRIPTIVES calculates Z scores, it now omits cases filtered
46 by the current FILTER settings.
48 * PSPPIRE graphical user interface improvements:
50 - Dialog boxes with source variable lists can now choose the sort
51 order; right click and select from the popup menu.
53 - File|Open now allows an encoding to be selected for opening
56 - File|Display Data File Information|External File... now allows an
57 encoding to be selected.
59 - A problem with the Means dialog has been resolved (bug #41433).
61 - Several problems related to the input of spreadsheets have been
62 fixed (bug #41657, #41620
64 * System file related improvements:
66 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
67 pick an encoding for reading a system file that does not identify
70 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
71 character encoding of string data in the system file.
73 - Variable labels over 255 bytes long are now accepted without
74 truncation (bug #41863).
76 - System files that contain duplicate variable names may now be
77 read successfully (bug #41475).
79 Changes from 0.8.1 to 0.8.2:
81 * Charts are now rendered with colours from the Tango palette instead
82 of fully saturated primaries.
84 * Support for new system file variants:
86 - PSPP can now read and write ZCOMPRESSED system files, which
87 compress data much more effectively than older "compressed"
88 files. (The older format is still supported.)
90 - PSPP can now decrypt encrypted system files, using the new
91 pspp-convert utility. The encrypted system file format is
92 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
93 do not directly read or write this format.
95 * Missing values for long string variables are now read from and
96 written to system files in an SPSS-compatible fashion.
98 (Earlier versions of PSPP that supported missing values for long
99 string variables wrote them to system files in an SPSS-incompatible
100 way. To fix the problem, read the system file with this version of
101 PSPP and then save a new copy of it.)
103 * pspp-convert, a new standalone utility for converting SPSS system
104 and portable files to other formats, is now included. The initial
105 version supports comma-separated value files as output format.
106 pspp-convert can also decrypt encrypted system files.
110 - zlib is now a required dependency. (Previously it was optional.)
112 Changes from 0.8.0 to 0.8.1:
118 * Changes to existing commands:
120 - CROSSTABS: The requirement that one expected count must be less than five
121 before Fishers Exact Test will be reported has been removed.
123 * PSPPIRE graphical user interface improvements:
125 - A new set of icons has been contributed.
127 - Syntax windows now parse syntax in "auto" mode, which in practice
128 should mean that both "batch" and "interactive" syntax now works,
129 instead of just "interactive" syntax.
131 - The variable pane of data windows now include a Role column.
135 - System files written by IBM SPSS 21 are now read without warnings.
137 - System files written by "VOXCO INTERVIEWER 4.3" are now read
140 - PSPPIRE should now more gracefully handle syntax files that contain
143 Changes from 0.6.2 to 0.8.0:
149 - DATAFILE ATTRIBUTES
156 - LOGISTIC REGRESSION
160 - PRESERVE and RESTORE
164 - SAVE TRANSLATE to CSV and tab-delimited files
166 - VARIABLE ATTRIBUTES
168 * Changes to existing commands:
170 - AUTORECODE has a new GROUP subcommand.
172 - CROSSTABS has been re-implemented to fix numerous bugs.
174 - EXAMINE: /MISSING=LISTWISE is now the default.
176 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
177 contains an INCLUDE or INSERT command, substitutions are not
178 applied to the included file.
180 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
182 - HOST has been updated to use more modern syntax.
184 - Most commands that work with data files now support a new
187 - MISSING VALUES can now assign missing values to long string
190 - ONEWAY: the POSTHOC subcommand is now implemented.
192 - The following new subcommands to NPAR TESTS have been implemented:
193 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
194 MCNEMAR, SIGN, WILCOXON, and RUNS
196 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
197 DPROMPT subcommands. The defaults are now fixed values.
199 - SHOW now has a JOURNAL subcommand, to show the location of the
202 - VALUE LABELS can now assign value labels to long string
205 * Other language changes:
207 - The new DATASET commands replace the "scratch file" PSPP
208 extension, which is no longer supported.
210 - Strings may now include arbitrary Unicode code points specified
211 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
212 code point U+1D11E, the musical G clef character, may be
213 expressed as U'1D11E'.
215 See the "Tokens" section in the PSPP manual for more information.
217 - In previous versions of PSPP, in a string expressed in
218 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
219 bytes in the locale encoding. In this version of PSPP, X'hh'
220 syntax always expresses bytes in UTF-8 encoding.
222 See the "Tokens" section in the PSPP manual for more information.
224 * PSPPIRE graphical user interface improvements:
226 - Added support for non-ASCII characters in strings, labels and
229 - A "Split Window" function is available, which makes it easier to
230 see different parts of a large data file.
232 - Data files can now be opened by specifing their name as the first
233 argument. This means that on a properly configured desktop, double
234 clicking on an icon will open the file.
236 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
237 via using an "intelligent" application assistant dialog.
241 - The new "cairo" output driver supports output in PostScript, PDF,
242 and SVG formats. Its functionality is a superset of that of the
243 "postscript" driver, which has been removed. You must have Cairo
244 and Pango installed to build the "cairo" driver.
246 - Charts are now produced with Cairo and Pango, instead of libplot.
247 Without them, the new graphing features will not work. If you do
248 not have Cairo and Pango installed, you must run `configure' with
251 - The plain text output driver now properly supports multibyte UTF-8
252 characters, including double-width characters and combining
255 - Output to OpenDocument format is now supported.
257 - The HTML output is much improved.
259 * The "pspp" program has a new option --batch (or -b) that selects
260 "batch" syntax mode. In previous versions of PSPP this syntax mode
261 was the default. Now a new "auto" syntax mode is the default. In
262 "auto" mode, PSPP interprets most syntax files correctly regardless
263 of their intended syntax mode.
265 See the "Syntax Variants" section in the PSPP manual for more
268 * The "pspp" program has a new option --syntax-encoding that
269 specifies the encoding for syntax files listed on the command line,
270 as well as the default encoding for syntax files included with
271 INCLUDE or INSERT. The default is to accept the system locale
272 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
273 one the system file uses.
275 See the documentation for the INSERT command in the PSPP manual for
278 * Text data files that PRINT and WRITE creates now use the system
279 native line ends by default (CRLF on Windows, LF only elsewhere).
280 Use the new ENDS subcommand on FILE HANDLE to override the default.
282 * A new Perl module allows Perl programs to read and write PSPP
285 * A tutorial chapter has been added to the user manual.
287 Changes from 0.6.1 to 0.6.2:
291 - Dutch, thanks to Harry Thijssen.
293 - Brazilian Portuguese, thanks to Michel Boaventura.
295 Thanks for translations are also due to the coordinators at
296 translationproject.org.
298 * Statistical bug fixes:
300 - REGRESSION: Report correct standard error of the estimate (bug
303 - T-TEST: Report correct significance of paired sample T-test in
304 the common case (bug #26936) and corner cases. Thanks to Mike
305 Griffiths and Matej Cepl for reporting these bugs.
307 * Build fixes and changes:
309 - Fix build with GTK+ 2.17.4 and later.
311 - Make running "make" after running "configure" with different
312 settings reliably rebuild version.c.
314 - Cygwin and MinGW build fixes.
316 - Fixes for building with recent gnulib.
318 - The Makefile now honors two new variables, PSPP_LDFLAGS and
319 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
320 binaries, respectively. This makes building easier for some
323 - Fixes for "configure --enable-relocatable" (bug #25508).
325 * Data file bug fixes and changes:
327 - Fix reading text data files that contain a mix of white space
328 and commas. Now "a ,b" is treated as two fields containing "a"
329 and "b"; previously it was treated as three, with an empty field
332 - Fix writing corrupted .sav files on Windows.
334 - Fix writing variable labels longer than 252 bytes to save files.
335 Thanks to Robert Westlund for reporting this bug.
337 - Fix writing corrupted .por files (bug #26034).
339 - Fix reading .por files whose initial lines are not padded out
340 with spaces as expected.
342 - PSPP will no longer issue warnings about some .sav file records
343 or values that it does not understand. These warnings were
344 harmless, but needlessly alarmed some users.
346 - Fix crash reading empty string fields from PostgreSQL databases.
348 * Bug fixes that affect PSPP and PSPPIRE:
350 - Users may now control precision of output statistics. Instead
351 of hard coding the width and decimals of output numbers, respect
352 the default format in most instances. Counts are now normally
353 displayed with the format of the weight variable, if any.
355 - Fix crash when an INSERT command specifies the name of a file
356 that does not exist (bug #24569).
358 - Fix crash when CROSSTABS specifies a long-string variable (bugs
361 - Fix crash drawing pie charts with many segments.
363 - Fix crash when NUMERIC specifies an invalid format.
365 * PSPPIRE bug fixes and changes:
367 - On Windows, write the output file to the user's home directory
368 instead of the current directory, to better match user
371 - Some data editor fixes.
375 - Fix typo in BINOMIAL section of user manual (bug #25892).
377 Changes from 0.6.0 to 0.6.1:
379 * Statistical bug fixes:
381 - Report correct standardized regression coefficients in linear
382 regression output (bug #23567).
384 * Bug fixes that affect PSPP and PSPPIRE:
386 - Avoid crash with pie charts (bug #24014).
388 - Don't append % to count totals (bug #24003).
390 - Don't crash on bad input (bug #24031).
392 - Don't crash if "end data." is not left aligned (bug #24115).
394 - Change default workspace value to 64 MB, to avoid unnecessary
395 disk accesses on modern machines.
399 - Add ".sav" or ".por" suffix to filename when saving with Save_As
402 - Make it possible to reopen the output window on Windows (bug
405 - A POSIX regular expression library is now included and used
406 automatically if the host does not have one or has one that is
409 * Build fixes and changes:
411 - Work around bug in GSL that prevented build with recent GCC
412 versions without manually adding -fgnu89-inline to CFLAGS.
414 - Also warn about missing prerequisites as we encounter them (bug
417 - Distribute necessary files to allow users working from the
418 distributed tarball to configure with --enable-gui-tools.
420 - Append $(EXEEXT_FOR_BUILD) to output file name when building
421 q2c, fixing build problems on Windows.
423 - GSL 1.8 or later is now required.
425 - Build errors with --enable-relocatable were fixed.
427 * The German translations were removed, since native German speakers
428 found them too poor to be useful.
430 Changes from 0.4.0 to 0.6.0:
432 * The PSPP license is now version 3 or later of the GNU General
433 Public License. Previously, it was version 2 or later.
435 * PSPP now has a graphical interface, called PSPPIRE. This
436 interface allows you to enter data and variable definitions
437 interactively. Commands may be executed in syntax form, or by
438 using the interactive dialog boxes available from the dropdown
441 * A few sample syntax files are now included in the `examples'
444 * Numerous major and minor bugs have been fixed.
448 * The INSTALL file now reflects the details of how to install
449 PSPP. It is a tailored version of the generic installation
450 instructions, instead of a verbatim copy.
452 * iconv, which is ordinarily installed as part of a Unix-like
453 system, is now required. If you don't have it already, you can
454 install GNU libiconv (http://www.gnu.org/software/libiconv/).
456 * libxml2 and zlib are new optional dependencies. They are
457 required to use PSPP's support for reading Gnumeric files.
459 Statistical procedure changes:
461 * REGRESSION is a new procedure for fitting linear models to data
462 via least-squares estimation.
464 * NPAR TESTS is a new procedure for non-parametric tests. In this
465 release, it supports binomial and chi-square tests.
467 * RANK is a new procedure to rank variables. It supports numerous
470 * FREQUENCIES can now output histograms and pie charts. These
471 features were present in earlier releases, but not documented.
473 User interface changes:
475 * In many situations where PSPP once terminated with a fatal
476 error, PSPP now recovers and continues execution.
478 * PSPP is now able to start up and run even if it cannot find its
481 * Journaling of interactive commands to a disk file is now
482 implemented. By default, journaling is enabled, to a file named
483 `pspp.jnl' in the current directory. SET JOURNAL may be used to
486 * The use of `+' between syntax file names on the command line to
487 prevent the dictionary from being cleared between their
488 executions is no longer supported. All syntax files are now
489 executed as if `+' had been specified.
491 * The -d/--define and -u/--undef command line options are no
492 longer supported. Instead, use /usr/bin/env or shell primitives
493 to define or clear environment variables before invoking PSPP.
495 * If a syntax file named named `rc' is found in a configuration
496 directory (such as $HOME/.pspp), it is executed before any
497 syntax file specified on the command line. The -r or
498 --no-statrc command line option may be used to disable this
503 * Output configuration options have changed. Please refer to the
504 manual for a full description of the available options.
506 In consequence, you will need to reinstall your "devices" file.
507 "make install" will do this for you.
509 * Most error messages are now written to PSPP output files by
510 default. SET ERROR can be used to disable this behavior.
512 * When invoked interactively, PSPP now by default produces output
513 on the terminal, piping it through the "more" program.
514 Previously, by default output was written only to file
515 pspp.list. On most terminals, the page length used for output
516 automatically adapts to the terminal size, even if the terminal
521 - This driver now supports charts in output. Charts are written
522 as separate files that the main output file refers to. By
523 default, charts are written in PNG format to files named
524 pspp-1.png, pspp-2.png, and so on.
526 - Configurations are provided that use VT100 (and xterm)
527 line-drawing characters in tables. The option "-o list-vt100"
528 requests use of this device for output to pspp.list.
532 - The default paper size is now determined using the PAPERSIZE
533 environment variable, or the LC_PAPER locale category on
534 systems that support it. If these are not set, the default is
535 now A4, instead of US letter. To make US letter the default,
536 set PAPERSIZE to "letter" in your environment.
538 - Font metrics are now read from AFM files, instead of
539 Groff-format metrics files. PostScript fonts can now be
542 In consequence, you will need to install an AFM file for each
543 font used in PostScript output. "make install" will install
544 AFM files for the standard PostScript fonts, including the
545 ones that the PostScript driver uses by default.
547 - Standard paper sizes no longer need to be specified through a
548 configuration file. The "papersize" configuration file is no
549 longer needed, or supported.
551 - The PostScript prologue is no longer obtained from the
552 "ps-prologue" configuration file. This configuration file is
553 no longer needed, or supported.
557 - The HTML prologue is no longer obtained from the
558 "html-prologue" configuration file. This configuration file
559 is no longer needed, or supported.
561 Command language changes:
563 * The following commands are new:
565 - GET DATA, which currently supports reading Gnumeric files and
566 text data files. It will be extended later to read other
567 types of foreign data.
569 - CD, to change the current directory.
571 - INSERT, to execute a syntax file.
573 - DELETE VARIABLES, to remove variables from the active file
576 - ADD DOCUMENT, to add text to active file documents.
578 - CLOSE FILE HANDLE (a PSPP extension; see below).
580 - XEXPORT, a PSPP extension that is a transformation equivalent
583 * The following functions for transformation expressions are new:
585 - DATEDIFF, for computing the difference of two dates.
587 - DATESUM, for advancing a date by a specified duration.
589 - VALUELABEL, to obtain the value label for a value.
591 * PSPP now supports very long string variables (over 255 bytes
594 * MATCH FILES now supports the FIRST and LAST subcommands.
596 * Previous versions of PSPP prohibited using commands to both read and
597 write a single file at the same time. Now, PSPP allows this, and
598 the new version of the file atomically replaces the old version.
600 * The following commands are no longer available. They will be
601 re-implemented in a later release:
603 - CLEAR TRANSFORMATIONS
609 * The PROCESS IF command, which was deprecated, has been removed.
610 You may replace any usage of it by SELECT IF following
611 TEMPORARY, which has the same effect.
613 * The output format for variables created by VECTOR may now be
614 specified as part of the VECTOR syntax.
616 "Scratch files", a new PSPP extension:
618 A scratch file, like a system file, consists of a dictionary and
619 any number of cases. Small scratch files are stored in memory;
620 one that grows too large is written to disk. By default, any file
621 handle whose name begins with # is assumed to refer to a scratch
624 Scratch files can be used just about anywhere a system or portable
625 file can be used. Also, portable files are now allowed in most
626 places that system files were allowed in previous PSPP version.
628 A new CLOSE FILE HANDLE command allows the storage associated with
629 scratch files to be freed. It also allows file handles to be
630 reassigned to new files.
632 For more information on scratch files, refer to the "File Handles"
633 section in the PSPP manual. For specifics of what commands now
634 allow what kinds of files to be specified, refer to the
635 documentation on those particular commands.
639 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
640 translation, are now supported. Use FILE HANDLE to specify the
641 format of these files.
643 * Little-endian, big-endian, and VAX-endian formats are now
644 supported for integer binary formats when reading and writing
645 data files. The new RIB and WIB subcommands on the SET command
646 control endianness of integer data. The default is the host's
649 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
650 floating point binary formats when reading and writing data
651 files. The new RRB and WRB subcommands on the SET command
652 control the floating point format. The default is the host's
653 native floating point format.
655 * DATA LIST now supports the SKIP subcommand, to skip records at
656 the beginning of a file. For compatibility, DATA LIST now
657 treats N format as F format for FREE and LIST format input.
659 * The SAVE and XSAVE commands now support the UNSELECTED,
660 PERMISSIONS, NAMES, and MAP subcommands.
662 * The EXPORT command has been re-implemented to obtain better
663 results. Support for the UNSELECTED, DIGITS, and TYPE
664 subcommands has been added.
666 * For compatibility, PRINT now inserts a space at the beginning of
667 every output line, even lines that would otherwise be blank,
668 when OUTFILE is specified. (The behavior of WRITE is
671 * For compatibility, PRINT EJECT now inserts the digit `1' at the
672 beginning of each line that should begin a new page.
674 * For compatibility, WRITE now outputs the system-missing value as
675 a field filled with spaces. Binary formats are an exception.
676 (The behavior of PRINT is unchanged.)
680 * Input and output format descriptions have been rewritten. They
681 now precisely describe what is accepted on input and written on
684 * The descriptions of the PSPP system and portable file formats
685 have been extensively revised and improved.
687 For developers, the build system now requires Autoconf 2.60 and
690 Changes from 0.3.0 to 0.4.0:
692 Changes in build dependencies:
694 * The GNU Scientific Library (libgsl), version 1.6 or later, is
697 * libplot from GNU plotutils is optional. Without it, the new
698 graphing features will not work. If you do not have it
699 installed, you must run `configure' with --without-libplot.
701 * libgmp2 is no longer a dependency.
703 Newly implemented commands and statistical features:
705 * EXAMINE, including its graphing features.
707 * FREQUENCIES now supports percentiles.
715 * SORT CASES now sorts stably, that is, two cases with equal sort
716 criteria will be in the same relative order before and after the
719 * T-TEST (re-written).
721 * DATE and USE. These commands are parsed but otherwise ignored,
722 to enhance compatibility with certain command files that invoke
725 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
726 currently have no effect on PSPP output, but their values are
727 written to and read from system files and thus may affect
728 third-party software.
730 * SET EPOCH implemented.
732 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
735 * FILE HANDLE now supports custom tab widths.
737 Long variable names (and other identifiers) are now supported. Up
738 to the first 64 bytes of each identifier is significant. PSPP now
739 reads and writes system files compatible with SPSS version 12.
741 New --algorithm and --syntax command line options allow
742 SPSS-compatible or enhanced modes to be selected.
744 Support for transformation expressions has been rewritten and
745 significantly improved. Refer to the manual for details.
747 Calculation of moments (mean, standard deviation, kurtosis,
748 skewness) has been rewritten and should now be more accurate. In
749 --algorithm=enhanced mode moments may be more accurate than SPSS in
752 Numerous bugs have been fixed, too many to mention here. Many new
753 tests have been added, leading to the discovery and fixing of many
756 The ASCII output driver can now squeeze multiple blank lines into
759 Much of the code has been rewritten and refactored. It is now much
762 The FILE TYPE and REPEATING DATA commands have been disabled for
763 this release because their implementations were deemed too buggy to
764 be useful. They will be fixed and replaced in a future release.
766 New pspp-mode for Emacs (in pspp-mode.el).
768 Added rudimentary command-line completion for interactive input.
770 lib/julcal and lib/dcdflib are no longer used, so they have been
773 For developers, the build system now requires Autoconf 2.58 and
774 Automake 1.7. The included gettext has been updated to version
777 Some reports state that Texinfo 4.8, the latest version, may be
778 necessary to successfully format the documentation on some systems.
780 Version 0.3.0 changes since 0.2.3:
784 * Using alphanumeric variables in functions under AGGREGATE
787 * Under certain circumstances, the final case would be omitted
788 from the results of an AGGREGATE operation. Fixed.
790 * Undefined behavior was invoked by referencing a freed pointer
791 under certain circumstances. Fixed.
793 * A wrong record size was displayed when paging the active file to
796 * Not having enough temporary space for sorting caused a core
799 * Syntax errors in function descriptions on AGGREGATE caused core
802 * A null pointer was dereferenced, causing a core dump, when
803 PERCENTILES was specified on FREQUENCIES. This fixes the
804 problem, but PSPP still doesn't calculate percentiles.
806 * SORT always sorted in ascending order. Fixed.
808 * Some minor memory leaks in the expression parser were removed.
810 * Many assertions fixed for strict ANSI C compliance.
814 * SET ECHO ON now implemented, but turned off by default.
816 * PRINT specifier supported on END REPEAT.
820 * System libgmp2 library is used if installed instead of
821 unconditionally using the included libgmp2 subset.

825 * Added CORRELATIONS command parser, but not implemented.
827 Version 0.2.3 changes since 0.2.2:
831 * SPLIT FILE with a string variable caused a core dump. Fixed.
833 * Nested INCLUDEs didn't work. Fixed.
835 * The MATCH FILES procedure set the values of variables not present
836 to 0. It should have been SYSMIS. This is now fixed.
838 * The REMARK command was too aggressive about skipping lines. It
839 didn't like being the last command in a file.
841 * Comment parsing wasn't consistent with the rest of the code in its
842 idea of where one command ends and another starts. This meant
843 that sometimes commands would be mysteriously ignored. Thanks to
844 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
846 * The TABLE subcommand on MATCH FILES worked only erratically at
847 best. This fixes it. Thanks to Dr. Dirk Melcher
848 <BZN-mdksh@t-online.de> for reporting this bug.
850 * VARIABLE LABELS rejected a slash before the first variable
851 specification, contradicting the documentation. Thanks to Walter
852 M. Gray <graywm@northernc.on.ca> for reporting this bug.
854 * Because of an incorrect optimization in memory allocation,
855 CROSSTABS sometimes segfaulted when asked to output multiple
856 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
859 * CROSSTABS didn't display value labels for column and row
860 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
863 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
864 <BZN-mdksh@t-online.de> for reporting this bug.

879 * CROSSTABS didn't display value labels for column and row
880 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
883 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
884 <BZN-mdksh@t-online.de> for reporting this bug.
886 * MATCH FILES corrupted memory and dumped core on some syntax
889 * MATCH FILES should set numeric values not available to the
890 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
891 <BZN-mdksh@t-online.de> for reporting this bug.
893 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
894 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.

899 Hankin <hankin@rogue.consultco.com> for pointing this out.
901 * The SAVE procedure didn't save long string variables properly.
902 Fixed by this patch. Thanks to Hankin
903 <hankin@rogue.consultco.com> for this patch.
905 * Minor documentation fixes for MATCH FILES.

911 * Fix behavior of PRINT SPACE for negative arguments.
913 * Fix reading some unusual system files.
915 * Fix LIST problems with very long variables. Thanks to Hankin
916 <hankin@dunno.com> for this bug report.
