5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * The graphical user interface uses Gtk+ version 3 instead of version 2.
10 Accordingly, it has a somewhat different look and feel.
12 Changes from 0.8.4 to 0.8.5:
14 * The FREQUENCIES and CROSSTABS commands can now generate barcharts.
16 * The FACTOR command can now perform PROMAX rotations.
18 * SPSS/PC+ system files are now supported on GET and other commands
19 that read SPSS system files. The pspp-convert program can now read
20 SPSS/PC+ system files. Writing the obsolete SPSS/PC+ system file
21 format is not supported.
23 * SYSFILE INFO can now read SPSS/PC+ system files and SPSS portable
26 * FREQUENCIES: A bug was fixed where an assertion failure occured
27 when an empty dataset was presented.
29 * The GRAPH command is now available. Initially it supports
30 scatterplots and histograms.
32 * The RND operator in expressions now supports additional operands
33 for rounding to values other than integers and to indicate a level
34 of rounding fuzz. The default rounding fuzz may now be controlled
35 and displayed with SET FUZZBITS and SHOW FUZZBITS, respectively.
37 Changes from 0.8.3 to 0.8.4:
39 * Formatting of SYSFILE INFO output was made easier to read.
41 * Bug fixes, including the following notable ones:
43 - FREQUENCIES works properly for string variables. (This bug was
46 - CROSSTABS now correctly computes all of the measures that it
47 offers. Some measures have been removed because they were not
50 - The NPAR TESTS calculation of significance for the RUNS
51 subcommand has been corrected.
53 - Planned comparisons in ONEWAY ANOVA now correctly handle negative
56 - The COUNT command now correctly treats missing values as
59 - Conformance fixes to Open Document output format.
61 Changes from 0.8.2 to 0.8.3:
63 * Independent T-Tests displayed the standard error of the difference
64 and the confidence interval for the unequal variances case, where
65 the equal variances case should have been. This has been fixed.
67 * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
68 intervals for the coefficients to be printed.
70 * When DESCRIPTIVES calculates Z scores, it now omits cases filtered
71 by the current FILTER settings.
73 * PSPPIRE graphical user interface improvements:
75 - Dialog boxes with source variable lists can now choose the sort
76 order; right click and select from the popup menu.
78 - File|Open now allows an encoding to be selected for opening
81 - File|Display Data File Information|External File... now allows an
82 encoding to be selected.
84 - A problem with the Means dialog has been resolved (bug #41433).
86 - Several problems related to the input of spreadsheets have been
87 fixed (bug #41657, #41620
89 * System file related improvements:
91 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
92 pick an encoding for reading a system file that does not identify
95 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
96 character encoding of string data in the system file.
98 - Variable labels over 255 bytes long are now accepted without
99 truncation (bug #41863).
101 - System files that contain duplicate variable names may now be
102 read successfully (bug #41475).
104 Changes from 0.8.1 to 0.8.2:
106 * Charts are now rendered with colours from the Tango palette instead
107 of fully saturated primaries.
109 * Support for new system file variants:
111 - PSPP can now read and write ZCOMPRESSED system files, which
112 compress data much more effectively than older "compressed"
113 files. (The older format is still supported.)
115 - PSPP can now decrypt encrypted system files, using the new
116 pspp-convert utility. The encrypted system file format is
117 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
118 do not directly read or write this format.
120 * Missing values for long string variables are now read from and
121 written to system files in an SPSS-compatible fashion.
123 (Earlier versions of PSPP that supported missing values for long
124 string variables wrote them to system files in an SPSS-incompatible
125 way. To fix the problem, read the system file with this version of
126 PSPP and then save a new copy of it.)
128 * pspp-convert, a new standalone utility for converting SPSS system
129 and portable files to other formats, is now included. The initial
130 version supports comma-separated value files as output format.
131 pspp-convert can also decrypt encrypted system files.
135 - zlib is now a required dependency. (Previously it was optional.)
137 Changes from 0.8.0 to 0.8.1:
143 * Changes to existing commands:
145 - CROSSTABS: The requirement that one expected count must be less than five
146 before Fishers Exact Test will be reported has been removed.
148 * PSPPIRE graphical user interface improvements:
150 - A new set of icons has been contributed.
152 - Syntax windows now parse syntax in "auto" mode, which in practice
153 should mean that both "batch" and "interactive" syntax now works,
154 instead of just "interactive" syntax.
156 - The variable pane of data windows now include a Role column.
160 - System files written by IBM SPSS 21 are now read without warnings.
162 - System files written by "VOXCO INTERVIEWER 4.3" are now read
165 - PSPPIRE should now more gracefully handle syntax files that contain
168 Changes from 0.6.2 to 0.8.0:
174 - DATAFILE ATTRIBUTES
181 - LOGISTIC REGRESSION
185 - PRESERVE and RESTORE
189 - SAVE TRANSLATE to CSV and tab-delimited files
191 - VARIABLE ATTRIBUTES
193 * Changes to existing commands:
195 - AUTORECODE has a new GROUP subcommand.
197 - CROSSTABS has been re-implemented to fix numerous bugs.
199 - EXAMINE: /MISSING=LISTWISE is now the default.
201 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
202 contains an INCLUDE or INSERT command, substitutions are not
203 applied to the included file.
205 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
207 - HOST has been updated to use more modern syntax.
209 - Most commands that work with data files now support a new
212 - MISSING VALUES can now assign missing values to long string
215 - ONEWAY: the POSTHOC subcommand is now implemented.
217 - The following new subcommands to NPAR TESTS have been implemented:
218 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
219 MCNEMAR, SIGN, WILCOXON, and RUNS
221 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
222 DPROMPT subcommands. The defaults are now fixed values.
224 - SHOW now has a JOURNAL subcommand, to show the location of the
227 - VALUE LABELS can now assign value labels to long string
230 * Other language changes:
232 - The new DATASET commands replace the "scratch file" PSPP
233 extension, which is no longer supported.
235 - Strings may now include arbitrary Unicode code points specified
236 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
237 code point U+1D11E, the musical G clef character, may be
238 expressed as U'1D11E'.
240 See the "Tokens" section in the PSPP manual for more information.
242 - In previous versions of PSPP, in a string expressed in
243 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
244 bytes in the locale encoding. In this version of PSPP, X'hh'
245 syntax always expresses bytes in UTF-8 encoding.
247 See the "Tokens" section in the PSPP manual for more information.
249 * PSPPIRE graphical user interface improvements:
251 - Added support for non-ASCII characters in strings, labels and
254 - A "Split Window" function is available, which makes it easier to
255 see different parts of a large data file.
257 - Data files can now be opened by specifing their name as the first
258 argument. This means that on a properly configured desktop, double
259 clicking on an icon will open the file.
261 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
262 via using an "intelligent" application assistant dialog.
266 - The new "cairo" output driver supports output in PostScript, PDF,
267 and SVG formats. Its functionality is a superset of that of the
268 "postscript" driver, which has been removed. You must have Cairo
269 and Pango installed to build the "cairo" driver.
271 - Charts are now produced with Cairo and Pango, instead of libplot.
272 Without them, the new graphing features will not work. If you do
273 not have Cairo and Pango installed, you must run `configure' with
276 - The plain text output driver now properly supports multibyte UTF-8
277 characters, including double-width characters and combining
280 - Output to OpenDocument format is now supported.
282 - The HTML output is much improved.
284 * The "pspp" program has a new option --batch (or -b) that selects
285 "batch" syntax mode. In previous versions of PSPP this syntax mode
286 was the default. Now a new "auto" syntax mode is the default. In
287 "auto" mode, PSPP interprets most syntax files correctly regardless
288 of their intended syntax mode.
290 See the "Syntax Variants" section in the PSPP manual for more
293 * The "pspp" program has a new option --syntax-encoding that
294 specifies the encoding for syntax files listed on the command line,
295 as well as the default encoding for syntax files included with
296 INCLUDE or INSERT. The default is to accept the system locale
297 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
298 one the system file uses.
300 See the documentation for the INSERT command in the PSPP manual for
303 * Text data files that PRINT and WRITE creates now use the system
304 native line ends by default (CRLF on Windows, LF only elsewhere).
305 Use the new ENDS subcommand on FILE HANDLE to override the default.
307 * A new Perl module allows Perl programs to read and write PSPP
310 * A tutorial chapter has been added to the user manual.
312 Changes from 0.6.1 to 0.6.2:
316 - Dutch, thanks to Harry Thijssen.
318 - Brazilian Portuguese, thanks to Michel Boaventura.
320 Thanks for translations are also due to the coordinators at
321 translationproject.org.
323 * Statistical bug fixes:
325 - REGRESSION: Report correct standard error of the estimate (bug
328 - T-TEST: Report correct significance of paired sample T-test in
329 the common case (bug #26936) and corner cases. Thanks to Mike
330 Griffiths and Matej Cepl for reporting these bugs.
332 * Build fixes and changes:
334 - Fix build with GTK+ 2.17.4 and later.
336 - Make running "make" after running "configure" with different
337 settings reliably rebuild version.c.
339 - Cygwin and MinGW build fixes.
341 - Fixes for building with recent gnulib.
343 - The Makefile now honors two new variables, PSPP_LDFLAGS and
344 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
345 binaries, respectively. This makes building easier for some
348 - Fixes for "configure --enable-relocatable" (bug #25508).
350 * Data file bug fixes and changes:
352 - Fix reading text data files that contain a mix of white space
353 and commas. Now "a ,b" is treated as two fields containing "a"
354 and "b"; previously it was treated as three, with an empty field
357 - Fix writing corrupted .sav files on Windows.
359 - Fix writing variable labels longer than 252 bytes to save files.
360 Thanks to Robert Westlund for reporting this bug.
362 - Fix writing corrupted .por files (bug #26034).
364 - Fix reading .por files whose initial lines are not padded out
365 with spaces as expected.
367 - PSPP will no longer issue warnings about some .sav file records
368 or values that it does not understand. These warnings were
369 harmless, but needlessly alarmed some users.
371 - Fix crash reading empty string fields from PostgreSQL databases.
373 * Bug fixes that affect PSPP and PSPPIRE:
375 - Users may now control precision of output statistics. Instead
376 of hard coding the width and decimals of output numbers, respect
377 the default format in most instances. Counts are now normally
378 displayed with the format of the weight variable, if any.
380 - Fix crash when an INSERT command specifies the name of a file
381 that does not exist (bug #24569).
383 - Fix crash when CROSSTABS specifies a long-string variable (bugs
386 - Fix crash drawing pie charts with many segments.
388 - Fix crash when NUMERIC specifies an invalid format.
390 * PSPPIRE bug fixes and changes:
392 - On Windows, write the output file to the user's home directory
393 instead of the current directory, to better match user
396 - Some data editor fixes.
400 - Fix typo in BINOMIAL section of user manual (bug #25892).
402 Changes from 0.6.0 to 0.6.1:
404 * Statistical bug fixes:
406 - Report correct standardized regression coefficients in linear
407 regression output (bug #23567).
409 * Bug fixes that affect PSPP and PSPPIRE:
411 - Avoid crash with pie charts (bug #24014).
413 - Don't append % to count totals (bug #24003).
415 - Don't crash on bad input (bug #24031).
417 - Don't crash if "end data." is not left aligned (bug #24115).
419 - Change default workspace value to 64 MB, to avoid unnecessary
420 disk accesses on modern machines.
424 - Add ".sav" or ".por" suffix to filename when saving with Save_As
427 - Make it possible to reopen the output window on Windows (bug
430 - A POSIX regular expression library is now included and used
431 automatically if the host does not have one or has one that is
434 * Build fixes and changes:
436 - Work around bug in GSL that prevented build with recent GCC
437 versions without manually adding -fgnu89-inline to CFLAGS.
439 - Also warn about missing prerequisites as we encounter them (bug
442 - Distribute necessary files to allow users working from the
443 distributed tarball to configure with --enable-gui-tools.
445 - Append $(EXEEXT_FOR_BUILD) to output file name when building
446 q2c, fixing build problems on Windows.
448 - GSL 1.8 or later is now required.
450 - Build errors with --enable-relocatable were fixed.
452 * The German translations were removed, since native German speakers
453 found them too poor to be useful.
455 Changes from 0.4.0 to 0.6.0:
457 * The PSPP license is now version 3 or later of the GNU General
458 Public License. Previously, it was version 2 or later.
460 * PSPP now has a graphical interface, called PSPPIRE. This
461 interface allows you to enter data and variable definitions
462 interactively. Commands may be executed in syntax form, or by
463 using the interactive dialog boxes available from the dropdown
466 * A few sample syntax files are now included in the `examples'
469 * Numerous major and minor bugs have been fixed.
473 * The INSTALL file now reflects the details of how to install
474 PSPP. It is a tailored version of the generic installation
475 instructions, instead of a verbatim copy.
477 * iconv, which is ordinarily installed as part of a Unix-like
478 system, is now required. If you don't have it already, you can
479 install GNU libiconv (http://www.gnu.org/software/libiconv/).
481 * libxml2 and zlib are new optional dependencies. They are
482 required to use PSPP's support for reading Gnumeric files.
484 Statistical procedure changes:
486 * REGRESSION is a new procedure for fitting linear models to data
487 via least-squares estimation.
489 * NPAR TESTS is a new procedure for non-parametric tests. In this
490 release, it supports binomial and chi-square tests.
492 * RANK is a new procedure to rank variables. It supports numerous
495 * FREQUENCIES can now output histograms and pie charts. These
496 features were present in earlier releases, but not documented.
498 User interface changes:
500 * In many situations where PSPP once terminated with a fatal
501 error, PSPP now recovers and continues execution.
503 * PSPP is now able to start up and run even if it cannot find its
506 * Journaling of interactive commands to a disk file is now
507 implemented. By default, journaling is enabled, to a file named
508 `pspp.jnl' in the current directory. SET JOURNAL may be used to
511 * The use of `+' between syntax file names on the command line to
512 prevent the dictionary from being cleared between their
513 executions is no longer supported. All syntax files are now
514 executed as if `+' had been specified.
516 * The -d/--define and -u/--undef command line options are no
517 longer supported. Instead, use /usr/bin/env or shell primitives
518 to define or clear environment variables before invoking PSPP.
520 * If a syntax file named named `rc' is found in a configuration
521 directory (such as $HOME/.pspp), it is executed before any
522 syntax file specified on the command line. The -r or
523 --no-statrc command line option may be used to disable this
528 * Output configuration options have changed. Please refer to the
529 manual for a full description of the available options.
531 In consequence, you will need to reinstall your "devices" file.
532 "make install" will do this for you.
534 * Most error messages are now written to PSPP output files by
535 default. SET ERROR can be used to disable this behavior.
537 * When invoked interactively, PSPP now by default produces output
538 on the terminal, piping it through the "more" program.
539 Previously, by default output was written only to file
540 pspp.list. On most terminals, the page length used for output
541 automatically adapts to the terminal size, even if the terminal
546 - This driver now supports charts in output. Charts are written
547 as separate files that the main output file refers to. By
548 default, charts are written in PNG format to files named
549 pspp-1.png, pspp-2.png, and so on.
551 - Configurations are provided that use VT100 (and xterm)
552 line-drawing characters in tables. The option "-o list-vt100"
553 requests use of this device for output to pspp.list.
557 - The default paper size is now determined using the PAPERSIZE
558 environment variable, or the LC_PAPER locale category on
559 systems that support it. If these are not set, the default is
560 now A4, instead of US letter. To make US letter the default,
561 set PAPERSIZE to "letter" in your environment.
563 - Font metrics are now read from AFM files, instead of
564 Groff-format metrics files. PostScript fonts can now be
567 In consequence, you will need to install an AFM file for each
568 font used in PostScript output. "make install" will install
569 AFM files for the standard PostScript fonts, including the
570 ones that the PostScript driver uses by default.
572 - Standard paper sizes no longer need to be specified through a
573 configuration file. The "papersize" configuration file is no
574 longer needed, or supported.
576 - The PostScript prologue is no longer obtained from the
577 "ps-prologue" configuration file. This configuration file is
578 no longer needed, or supported.
582 - The HTML prologue is no longer obtained from the
583 "html-prologue" configuration file. This configuration file
584 is no longer needed, or supported.
586 Command language changes:
588 * The following commands are new:
590 - GET DATA, which currently supports reading Gnumeric files and
591 text data files. It will be extended later to read other
592 types of foreign data.
594 - CD, to change the current directory.
596 - INSERT, to execute a syntax file.
598 - DELETE VARIABLES, to remove variables from the active file
601 - ADD DOCUMENT, to add text to active file documents.
603 - CLOSE FILE HANDLE (a PSPP extension; see below).
605 - XEXPORT, a PSPP extension that is a transformation equivalent
608 * The following functions for transformation expressions are new:
610 - DATEDIFF, for computing the difference of two dates.
612 - DATESUM, for advancing a date by a specified duration.
614 - VALUELABEL, to obtain the value label for a value.
616 * PSPP now supports very long string variables (over 255 bytes
619 * MATCH FILES now supports the FIRST and LAST subcommands.
621 * Previous versions of PSPP prohibited using commands to both read and
622 write a single file at the same time. Now, PSPP allows this, and
623 the new version of the file atomically replaces the old version.
625 * The following commands are no longer available. They will be
626 re-implemented in a later release:
628 - CLEAR TRANSFORMATIONS
634 * The PROCESS IF command, which was deprecated, has been removed.
635 You may replace any usage of it by SELECT IF following
636 TEMPORARY, which has the same effect.
638 * The output format for variables created by VECTOR may now be
639 specified as part of the VECTOR syntax.
641 "Scratch files", a new PSPP extension:
643 A scratch file, like a system file, consists of a dictionary and
644 any number of cases. Small scratch files are stored in memory;
645 one that grows too large is written to disk. By default, any file
646 handle whose name begins with # is assumed to refer to a scratch
649 Scratch files can be used just about anywhere a system or portable
650 file can be used. Also, portable files are now allowed in most
651 places that system files were allowed in previous PSPP version.
653 A new CLOSE FILE HANDLE command allows the storage associated with
654 scratch files to be freed. It also allows file handles to be
655 reassigned to new files.
657 For more information on scratch files, refer to the "File Handles"
658 section in the PSPP manual. For specifics of what commands now
659 allow what kinds of files to be specified, refer to the
660 documentation on those particular commands.
664 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
665 translation, are now supported. Use FILE HANDLE to specify the
666 format of these files.
668 * Little-endian, big-endian, and VAX-endian formats are now
669 supported for integer binary formats when reading and writing
670 data files. The new RIB and WIB subcommands on the SET command
671 control endianness of integer data. The default is the host's
674 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
675 floating point binary formats when reading and writing data
676 files. The new RRB and WRB subcommands on the SET command
677 control the floating point format. The default is the host's
678 native floating point format.
680 * DATA LIST now supports the SKIP subcommand, to skip records at
681 the beginning of a file. For compatibility, DATA LIST now
682 treats N format as F format for FREE and LIST format input.
684 * The SAVE and XSAVE commands now support the UNSELECTED,
685 PERMISSIONS, NAMES, and MAP subcommands.
687 * The EXPORT command has been re-implemented to obtain better
688 results. Support for the UNSELECTED, DIGITS, and TYPE
689 subcommands has been added.
691 * For compatibility, PRINT now inserts a space at the beginning of
692 every output line, even lines that would otherwise be blank,
693 when OUTFILE is specified. (The behavior of WRITE is
696 * For compatibility, PRINT EJECT now inserts the digit `1' at the
697 beginning of each line that should begin a new page.
699 * For compatibility, WRITE now outputs the system-missing value as
700 a field filled with spaces. Binary formats are an exception.
701 (The behavior of PRINT is unchanged.)
705 * Input and output format descriptions have been rewritten. They
706 now precisely describe what is accepted on input and written on
709 * The descriptions of the PSPP system and portable file formats
710 have been extensively revised and improved.
712 For developers, the build system now requires Autoconf 2.60 and
715 Changes from 0.3.0 to 0.4.0:
717 Changes in build dependencies:
719 * The GNU Scientific Library (libgsl), version 1.6 or later, is
722 * libplot from GNU plotutils is optional. Without it, the new
723 graphing features will not work. If you do not have it
724 installed, you must run `configure' with --without-libplot.
726 * libgmp2 is no longer a dependency.
728 Newly implemented commands and statistical features:
730 * EXAMINE, including its graphing features.
732 * FREQUENCIES now supports percentiles.
740 * SORT CASES now sorts stably, that is, two cases with equal sort
741 criteria will be in the same relative order before and after the
744 * T-TEST (re-written).
746 * DATE and USE. These commands are parsed but otherwise ignored,
747 to enhance compatibility with certain command files that invoke
750 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
751 currently have no effect on PSPP output, but their values are
752 written to and read from system files and thus may affect
753 third-party software.
755 * SET EPOCH implemented.
757 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
760 * FILE HANDLE now supports custom tab widths.
762 Long variable names (and other identifiers) are now supported. Up
763 to the first 64 bytes of each identifier is significant. PSPP now
764 reads and writes system files compatible with SPSS version 12.
766 New --algorithm and --syntax command line options allow
767 SPSS-compatible or enhanced modes to be selected.
769 Support for transformation expressions has been rewritten and
770 significantly improved. Refer to the manual for details.
772 Calculation of moments (mean, standard deviation, kurtosis,
773 skewness) has been rewritten and should now be more accurate. In
774 --algorithm=enhanced mode moments may be more accurate than SPSS in
777 Numerous bugs have been fixed, too many to mention here. Many new
778 tests have been added, leading to the discovery and fixing of many
781 The ASCII output driver can now squeeze multiple blank lines into
784 Much of the code has been rewritten and refactored. It is now much
787 The FILE TYPE and REPEATING DATA commands have been disabled for
788 this release because their implementations were deemed too buggy to
789 be useful. They will be fixed and replaced in a future release.
791 New pspp-mode for Emacs (in pspp-mode.el).
793 Added rudimentary command-line completion for interactive input.
795 lib/julcal and lib/dcdflib are no longer used, so they have been
798 For developers, the build system now requires Autoconf 2.58 and
799 Automake 1.7. The included gettext has been updated to version
802 Some reports state that Texinfo 4.8, the latest version, may be
803 necessary to successfully format the documentation on some systems.
805 Version 0.3.0 changes since 0.2.3:
809 * Using alphanumeric variables in functions under AGGREGATE
812 * Under certain circumstances, the final case would be omitted
813 from the results of an AGGREGATE operation. Fixed.
815 * Undefined behavior was invoked by referencing a freed pointer
816 under certain circumstances. Fixed.
818 * A wrong record size was displayed when paging the active file to
821 * Not having enough temporary space for sorting caused a core
824 * Syntax errors in function descriptions on AGGREGATE caused core
827 * A null pointer was dereferenced, causing a core dump, when
828 PERCENTILES was specified on FREQUENCIES. This fixes the
829 problem, but PSPP still doesn't calculate percentiles.
831 * SORT always sorted in ascending order. Fixed.
833 * Some minor memory leaks in the expression parser were removed.
835 * Many assertions fixed for strict ANSI C compliance.
839 * SET ECHO ON now implemented, but turned off by default.
841 * PRINT specifier supported on END REPEAT.
845 * System libgmp2 library is used if installed instead of
846 unconditionally using the included libgmp2 subset.
848 * Extensive code cleanup, which continues.
850 * Added CORRELATIONS command parser, but not implemented.
852 Version 0.2.3 changes since 0.2.2:
856 * SPLIT FILE with a string variable caused a core dump. Fixed.
858 * Nested INCLUDEs didn't work. Fixed.
860 * The MATCH FILES procedure set the values of variables not present
861 to 0. It should have been SYSMIS. This is now fixed.
863 * The REMARK command was too aggressive about skipping lines. It
864 didn't like being the last command in a file.
866 * Comment parsing wasn't consistent with the rest of the code in its
867 idea of where one command ends and another starts. This meant
868 that sometimes commands would be mysteriously ignored. Thanks to
869 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
871 * The TABLE subcommand on MATCH FILES worked only erratically at
872 best. This fixes it. Thanks to Dr. Dirk Melcher
873 <BZN-mdksh@t-online.de> for reporting this bug.
875 * VARIABLE LABELS rejected a slash before the first variable
876 specification, contradicting the documentation. Thanks to Walter
877 M. Gray <graywm@northernc.on.ca> for reporting this bug.
879 * Because of an incorrect optimization in memory allocation,
880 CROSSTABS sometimes segfaulted when asked to output multiple
881 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
884 * CROSSTABS didn't display value labels for column and row
885 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
888 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
889 <BZN-mdksh@t-online.de> for reporting this bug.
891 * The TABLE subcommand on MATCH FILES worked only erratically at
892 best. This fixes it. Thanks to Dr. Dirk Melcher
893 <BZN-mdksh@t-online.de> for reporting this bug.
895 * VARIABLE LABELS rejected a slash before the first variable
896 specification, contradicting the documentation. Thanks to Walter
897 M. Gray <graywm@northernc.on.ca> for reporting this bug.
899 * Because of an incorrect optimization in memory allocation,
900 CROSSTABS sometimes segfaulted when asked to output multiple
901 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
904 * CROSSTABS didn't display value labels for column and row
905 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
908 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
909 <BZN-mdksh@t-online.de> for reporting this bug.
911 * MATCH FILES corrupted memory and dumped core on some syntax
914 * MATCH FILES should set numeric values not available to the
915 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
916 <BZN-mdksh@t-online.de> for reporting this bug.
918 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
919 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
923 * Some systems didn't like the way open_file was coded. Thanks to
924 Hankin <hankin@rogue.consultco.com> for pointing this out.
926 * The SAVE procedure didn't save long string variables properly.
927 Fixed by this patch. Thanks to Hankin
928 <hankin@rogue.consultco.com> for this patch.
930 * Minor documentation fixes for MATCH FILES.
932 Version 0.2.2 changes since 0.2.1:
936 * Fix behavior of PRINT SPACE for negative arguments.
938 * Fix reading some unusual system files.
940 * Fix LIST problems with very long variables. Thanks to Hankin
941 <hankin@dunno.com> for this bug report.
943 * Fix problems with some string format specifiers.
945 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
946 <BZN-mdksh@t-online.de> for reporting this bug.
948 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
949 Hankin <hankin@dunno.com> again on this one.
951 * Sometimes you may encounter a PSPP script that has to be
952 interpreted in interactive mode. Now you can use the -i flag to
955 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
956 `unused variable' warnings under gcc 2.7.2.3, fixing this will
961 * The files in gmp need the internationalization directory in
962 their include path. Thanks to OKUJI Yoshinori
963 <okuji@kuicr.kyoto-u.ac.jp> for pointing this out.
965 Version 0.2.1 changes since 0.2.0:
969 * Remember to include examples/ directory in distribution :-)
971 * Fixed gmp compile problems for some non-i386 architectures.
972 Thanks to Hans Olav Eggestad <olav@jordforsk.nlh.no> and others
975 * DATA LIST FREE and DATA LIST LIST parsing of input files is now
976 matches the documented behavior exactly, and error messages are
977 more helpful. Thanks to Mark H. Wood <mwood@IUPUI.Edu>.
979 Version 0.2.0 changes since 0.1.0:
981 Procedures now implemented:
982 * CROSSTABS. Please see documentation for caveats.
