5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * The GRAPH command is now available. Initially it support
10 scatterplots and histograms.
12 Changes from 0.8.3 to 0.8.4:
14 * Formatting of SYSFILE INFO output was made easier to read.
16 * Bug fixes, including the following notable ones:
18 - FREQUENCIES works properly for string variables. (This bug was
21 - CROSSTABS now correctly computes all of the measures that it
22 offers. Some measures have been removed because they were not
25 - The NPAR TESTS calculation of significance for the RUNS
26 subcommand has been corrected.
28 - Planned comparisons in ONEWAY ANOVA now correctly handle negative
31 - Conformance fixes to Open Document output format.
33 Changes from 0.8.2 to 0.8.3:
35 * Independent T-Tests displayed the standard error of the difference
36 and the confidence interval for the unequal variances case, where
37 the equal variances case should have been. This has been fixed.
39 * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
40 intervals for the coefficients to be printed.
42 * When DESCRIPTIVES calculates Z scores, it now omits cases filtered
43 by the current FILTER settings.
45 * PSPPIRE graphical user interface improvements:
47 - Dialog boxes with source variable lists can now choose the sort
48 order; right click and select from the popup menu.
50 - File|Open now allows an encoding to be selected for opening
53 - File|Display Data File Information|External File... now allows an
54 encoding to be selected.
56 - A problem with the Means dialog has been resolved (bug #41433).
58 - Several problems related to the input of spreadsheets have been
59 fixed (bug #41657, #41620
61 * System file related improvements:
63 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
64 pick an encoding for reading a system file that does not identify
67 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
68 character encoding of string data in the system file.
70 - Variable labels over 255 bytes long are now accepted without
71 truncation (bug #41863).
73 - System files that contain duplicate variable names may now be
74 read successfully (bug #41475).
76 Changes from 0.8.1 to 0.8.2:
78 * Charts are now rendered with colours from the Tango palette instead
79 of fully saturated primaries.
81 * Support for new system file variants:
83 - PSPP can now read and write ZCOMPRESSED system files, which
84 compress data much more effectively than older "compressed"
85 files. (The older format is still supported.)
87 - PSPP can now decrypt encrypted system files, using the new
88 pspp-convert utility. The encrypted system file format is
89 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
90 do not directly read or write this format.
92 * Missing values for long string variables are now read from and
93 written to system files in an SPSS-compatible fashion.
95 (Earlier versions of PSPP that supported missing values for long
96 string variables wrote them to system files in an SPSS-incompatible
97 way. To fix the problem, read the system file with this version of
98 PSPP and then save a new copy of it.)
100 * pspp-convert, a new standalone utility for converting SPSS system
101 and portable files to other formats, is now included. The initial
102 version supports comma-separated value files as output format.
103 pspp-convert can also decrypt encrypted system files.
107 - zlib is now a required dependency. (Previously it was optional.)
109 Changes from 0.8.0 to 0.8.1:
115 * Changes to existing commands:
117 - CROSSTABS: The requirement that one expected count must be less than five
118 before Fishers Exact Test will be reported has been removed.
120 * PSPPIRE graphical user interface improvements:
122 - A new set of icons has been contributed.
124 - Syntax windows now parse syntax in "auto" mode, which in practice
125 should mean that both "batch" and "interactive" syntax now works,
126 instead of just "interactive" syntax.
128 - The variable pane of data windows now include a Role column.
132 - System files written by IBM SPSS 21 are now read without warnings.
134 - System files written by "VOXCO INTERVIEWER 4.3" are now read
137 - PSPPIRE should now more gracefully handle syntax files that contain
140 Changes from 0.6.2 to 0.8.0:
146 - DATAFILE ATTRIBUTES
153 - LOGISTIC REGRESSION
157 - PRESERVE and RESTORE
161 - SAVE TRANSLATE to CSV and tab-delimited files
163 - VARIABLE ATTRIBUTES
165 * Changes to existing commands:
167 - AUTORECODE has a new GROUP subcommand.
169 - CROSSTABS has been re-implemented to fix numerous bugs.
171 - EXAMINE: /MISSING=LISTWISE is now the default.
173 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
174 contains an INCLUDE or INSERT command, substitutions are not
175 applied to the included file.
177 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
179 - HOST has been updated to use more modern syntax.
181 - Most commands that work with data files now support a new
184 - MISSING VALUES can now assign missing values to long string
187 - ONEWAY: the POSTHOC subcommand is now implemented.
189 - The following new subcommands to NPAR TESTS have been implemented:
190 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
191 MCNEMAR, SIGN, WILCOXON, and RUNS
193 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
194 DPROMPT subcommands. The defaults are now fixed values.
196 - SHOW now has a JOURNAL subcommand, to show the location of the
199 - VALUE LABELS can now assign value labels to long string
202 * Other language changes:
204 - The new DATASET commands replace the "scratch file" PSPP
205 extension, which is no longer supported.
207 - Strings may now include arbitrary Unicode code points specified
208 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
209 code point U+1D11E, the musical G clef character, may be
210 expressed as U'1D11E'.
212 See the "Tokens" section in the PSPP manual for more information.
214 - In previous versions of PSPP, in a string expressed in
215 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
216 bytes in the locale encoding. In this version of PSPP, X'hh'
217 syntax always expresses bytes in UTF-8 encoding.
219 See the "Tokens" section in the PSPP manual for more information.
221 * PSPPIRE graphical user interface improvements:
223 - Added support for non-ASCII characters in strings, labels and
226 - A "Split Window" function is available, which makes it easier to
227 see different parts of a large data file.
229 - Data files can now be opened by specifing their name as the first
230 argument. This means that on a properly configured desktop, double
231 clicking on an icon will open the file.
233 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
234 via using an "intelligent" application assistant dialog.
238 - The new "cairo" output driver supports output in PostScript, PDF,
239 and SVG formats. Its functionality is a superset of that of the
240 "postscript" driver, which has been removed. You must have Cairo
241 and Pango installed to build the "cairo" driver.
243 - Charts are now produced with Cairo and Pango, instead of libplot.
244 Without them, the new graphing features will not work. If you do
245 not have Cairo and Pango installed, you must run `configure' with
248 - The plain text output driver now properly supports multibyte UTF-8
249 characters, including double-width characters and combining
252 - Output to OpenDocument format is now supported.
254 - The HTML output is much improved.
256 * The "pspp" program has a new option --batch (or -b) that selects
257 "batch" syntax mode. In previous versions of PSPP this syntax mode
258 was the default. Now a new "auto" syntax mode is the default. In
259 "auto" mode, PSPP interprets most syntax files correctly regardless
260 of their intended syntax mode.
262 See the "Syntax Variants" section in the PSPP manual for more
265 * The "pspp" program has a new option --syntax-encoding that
266 specifies the encoding for syntax files listed on the command line,
267 as well as the default encoding for syntax files included with
268 INCLUDE or INSERT. The default is to accept the system locale
269 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
270 one the system file uses.
272 See the documentation for the INSERT command in the PSPP manual for
275 * Text data files that PRINT and WRITE creates now use the system
276 native line ends by default (CRLF on Windows, LF only elsewhere).
277 Use the new ENDS subcommand on FILE HANDLE to override the default.
279 * A new Perl module allows Perl programs to read and write PSPP
282 * A tutorial chapter has been added to the user manual.
284 Changes from 0.6.1 to 0.6.2:
288 - Dutch, thanks to Harry Thijssen.
290 - Brazilian Portuguese, thanks to Michel Boaventura.
292 Thanks for translations are also due to the coordinators at
293 translationproject.org.
295 * Statistical bug fixes:
297 - REGRESSION: Report correct standard error of the estimate (bug
300 - T-TEST: Report correct significance of paired sample T-test in
301 the common case (bug #26936) and corner cases. Thanks to Mike
302 Griffiths and Matej Cepl for reporting these bugs.
304 * Build fixes and changes:
306 - Fix build with GTK+ 2.17.4 and later.
308 - Make running "make" after running "configure" with different
309 settings reliably rebuild version.c.
311 - Cygwin and MinGW build fixes.
313 - Fixes for building with recent gnulib.
315 - The Makefile now honors two new variables, PSPP_LDFLAGS and
316 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
317 binaries, respectively. This makes building easier for some
320 - Fixes for "configure --enable-relocatable" (bug #25508).
322 * Data file bug fixes and changes:
324 - Fix reading text data files that contain a mix of white space
325 and commas. Now "a ,b" is treated as two fields containing "a"
326 and "b"; previously it was treated as three, with an empty field
329 - Fix writing corrupted .sav files on Windows.
331 - Fix writing variable labels longer than 252 bytes to save files.
332 Thanks to Robert Westlund for reporting this bug.
334 - Fix writing corrupted .por files (bug #26034).
336 - Fix reading .por files whose initial lines are not padded out
337 with spaces as expected.
339 - PSPP will no longer issue warnings about some .sav file records
340 or values that it does not understand. These warnings were
341 harmless, but needlessly alarmed some users.
343 - Fix crash reading empty string fields from PostgreSQL databases.
345 * Bug fixes that affect PSPP and PSPPIRE:
347 - Users may now control precision of output statistics. Instead
348 of hard coding the width and decimals of output numbers, respect
349 the default format in most instances. Counts are now normally
350 displayed with the format of the weight variable, if any.
352 - Fix crash when an INSERT command specifies the name of a file
353 that does not exist (bug #24569).
355 - Fix crash when CROSSTABS specifies a long-string variable (bugs
358 - Fix crash drawing pie charts with many segments.
360 - Fix crash when NUMERIC specifies an invalid format.
362 * PSPPIRE bug fixes and changes:
364 - On Windows, write the output file to the user's home directory
365 instead of the current directory, to better match user
368 - Some data editor fixes.
372 - Fix typo in BINOMIAL section of user manual (bug #25892).
374 Changes from 0.6.0 to 0.6.1:
376 * Statistical bug fixes:
378 - Report correct standardized regression coefficients in linear
379 regression output (bug #23567).
381 * Bug fixes that affect PSPP and PSPPIRE:
383 - Avoid crash with pie charts (bug #24014).
385 - Don't append % to count totals (bug #24003).
387 - Don't crash on bad input (bug #24031).
389 - Don't crash if "end data." is not left aligned (bug #24115).
391 - Change default workspace value to 64 MB, to avoid unnecessary
392 disk accesses on modern machines.
396 - Add ".sav" or ".por" suffix to filename when saving with Save_As
399 - Make it possible to reopen the output window on Windows (bug
402 - A POSIX regular expression library is now included and used
403 automatically if the host does not have one or has one that is
406 * Build fixes and changes:
408 - Work around bug in GSL that prevented build with recent GCC
409 versions without manually adding -fgnu89-inline to CFLAGS.
411 - Also warn about missing prerequisites as we encounter them (bug
414 - Distribute necessary files to allow users working from the
415 distributed tarball to configure with --enable-gui-tools.
417 - Append $(EXEEXT_FOR_BUILD) to output file name when building
418 q2c, fixing build problems on Windows.
420 - GSL 1.8 or later is now required.
422 - Build errors with --enable-relocatable were fixed.
424 * The German translations were removed, since native German speakers
425 found them too poor to be useful.
427 Changes from 0.4.0 to 0.6.0:
429 * The PSPP license is now version 3 or later of the GNU General
430 Public License. Previously, it was version 2 or later.
432 * PSPP now has a graphical interface, called PSPPIRE. This
433 interface allows you to enter data and variable definitions
434 interactively. Commands may be executed in syntax form, or by
435 using the interactive dialog boxes available from the dropdown
438 * A few sample syntax files are now included in the `examples'
441 * Numerous major and minor bugs have been fixed.
445 * The INSTALL file now reflects the details of how to install
446 PSPP. It is a tailored version of the generic installation
447 instructions, instead of a verbatim copy.
449 * iconv, which is ordinarily installed as part of a Unix-like
450 system, is now required. If you don't have it already, you can
451 install GNU libiconv (http://www.gnu.org/software/libiconv/).
453 * libxml2 and zlib are new optional dependencies. They are
454 required to use PSPP's support for reading Gnumeric files.
456 Statistical procedure changes:
458 * REGRESSION is a new procedure for fitting linear models to data
459 via least-squares estimation.
461 * NPAR TESTS is a new procedure for non-parametric tests. In this
462 release, it supports binomial and chi-square tests.
464 * RANK is a new procedure to rank variables. It supports numerous
467 * FREQUENCIES can now output histograms and pie charts. These
468 features were present in earlier releases, but not documented.
470 User interface changes:
472 * In many situations where PSPP once terminated with a fatal
473 error, PSPP now recovers and continues execution.
475 * PSPP is now able to start up and run even if it cannot find its
478 * Journaling of interactive commands to a disk file is now
479 implemented. By default, journaling is enabled, to a file named
480 `pspp.jnl' in the current directory. SET JOURNAL may be used to
483 * The use of `+' between syntax file names on the command line to
484 prevent the dictionary from being cleared between their
485 executions is no longer supported. All syntax files are now
486 executed as if `+' had been specified.
488 * The -d/--define and -u/--undef command line options are no
489 longer supported. Instead, use /usr/bin/env or shell primitives
490 to define or clear environment variables before invoking PSPP.
492 * If a syntax file named named `rc' is found in a configuration
493 directory (such as $HOME/.pspp), it is executed before any
494 syntax file specified on the command line. The -r or
495 --no-statrc command line option may be used to disable this
500 * Output configuration options have changed. Please refer to the
501 manual for a full description of the available options.
503 In consequence, you will need to reinstall your "devices" file.
504 "make install" will do this for you.
506 * Most error messages are now written to PSPP output files by
507 default. SET ERROR can be used to disable this behavior.
509 * When invoked interactively, PSPP now by default produces output
510 on the terminal, piping it through the "more" program.
511 Previously, by default output was written only to file
512 pspp.list. On most terminals, the page length used for output
513 automatically adapts to the terminal size, even if the terminal
518 - This driver now supports charts in output. Charts are written
519 as separate files that the main output file refers to. By
520 default, charts are written in PNG format to files named
521 pspp-1.png, pspp-2.png, and so on.
523 - Configurations are provided that use VT100 (and xterm)
524 line-drawing characters in tables. The option "-o list-vt100"
525 requests use of this device for output to pspp.list.
529 - The default paper size is now determined using the PAPERSIZE
530 environment variable, or the LC_PAPER locale category on
531 systems that support it. If these are not set, the default is
532 now A4, instead of US letter. To make US letter the default,
533 set PAPERSIZE to "letter" in your environment.
535 - Font metrics are now read from AFM files, instead of
536 Groff-format metrics files. PostScript fonts can now be
539 In consequence, you will need to install an AFM file for each
540 font used in PostScript output. "make install" will install
541 AFM files for the standard PostScript fonts, including the
542 ones that the PostScript driver uses by default.
544 - Standard paper sizes no longer need to be specified through a
545 configuration file. The "papersize" configuration file is no
546 longer needed, or supported.
548 - The PostScript prologue is no longer obtained from the
549 "ps-prologue" configuration file. This configuration file is
550 no longer needed, or supported.
554 - The HTML prologue is no longer obtained from the
555 "html-prologue" configuration file. This configuration file
556 is no longer needed, or supported.
558 Command language changes:
560 * The following commands are new:
562 - GET DATA, which currently supports reading Gnumeric files and
563 text data files. It will be extended later to read other
564 types of foreign data.
566 - CD, to change the current directory.
568 - INSERT, to execute a syntax file.
570 - DELETE VARIABLES, to remove variables from the active file
573 - ADD DOCUMENT, to add text to active file documents.
575 - CLOSE FILE HANDLE (a PSPP extension; see below).
577 - XEXPORT, a PSPP extension that is a transformation equivalent
580 * The following functions for transformation expressions are new:
582 - DATEDIFF, for computing the difference of two dates.
584 - DATESUM, for advancing a date by a specified duration.
586 - VALUELABEL, to obtain the value label for a value.
588 * PSPP now supports very long string variables (over 255 bytes
591 * MATCH FILES now supports the FIRST and LAST subcommands.
593 * Previous versions of PSPP prohibited using commands to both read and
594 write a single file at the same time. Now, PSPP allows this, and
595 the new version of the file atomically replaces the old version.
597 * The following commands are no longer available. They will be
598 re-implemented in a later release:
600 - CLEAR TRANSFORMATIONS
606 * The PROCESS IF command, which was deprecated, has been removed.
607 You may replace any usage of it by SELECT IF following
608 TEMPORARY, which has the same effect.
610 * The output format for variables created by VECTOR may now be
611 specified as part of the VECTOR syntax.
613 "Scratch files", a new PSPP extension:
615 A scratch file, like a system file, consists of a dictionary and
616 any number of cases. Small scratch files are stored in memory;
617 one that grows too large is written to disk. By default, any file
618 handle whose name begins with # is assumed to refer to a scratch
621 Scratch files can be used just about anywhere a system or portable
622 file can be used. Also, portable files are now allowed in most
623 places that system files were allowed in previous PSPP version.
625 A new CLOSE FILE HANDLE command allows the storage associated with
626 scratch files to be freed. It also allows file handles to be
627 reassigned to new files.
629 For more information on scratch files, refer to the "File Handles"
630 section in the PSPP manual. For specifics of what commands now
631 allow what kinds of files to be specified, refer to the
632 documentation on those particular commands.
636 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
637 translation, are now supported. Use FILE HANDLE to specify the
638 format of these files.
640 * Little-endian, big-endian, and VAX-endian formats are now
641 supported for integer binary formats when reading and writing
642 data files. The new RIB and WIB subcommands on the SET command
643 control endianness of integer data. The default is the host's
646 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
647 floating point binary formats when reading and writing data
648 files. The new RRB and WRB subcommands on the SET command
649 control the floating point format. The default is the host's
650 native floating point format.
652 * DATA LIST now supports the SKIP subcommand, to skip records at
653 the beginning of a file. For compatibility, DATA LIST now
654 treats N format as F format for FREE and LIST format input.
656 * The SAVE and XSAVE commands now support the UNSELECTED,
657 PERMISSIONS, NAMES, and MAP subcommands.
659 * The EXPORT command has been re-implemented to obtain better
660 results. Support for the UNSELECTED, DIGITS, and TYPE
661 subcommands has been added.
663 * For compatibility, PRINT now inserts a space at the beginning of
664 every output line, even lines that would otherwise be blank,
665 when OUTFILE is specified. (The behavior of WRITE is
668 * For compatibility, PRINT EJECT now inserts the digit `1' at the
669 beginning of each line that should begin a new page.
671 * For compatibility, WRITE now outputs the system-missing value as
672 a field filled with spaces. Binary formats are an exception.
673 (The behavior of PRINT is unchanged.)
677 * Input and output format descriptions have been rewritten. They
678 now precisely describe what is accepted on input and written on
681 * The descriptions of the PSPP system and portable file formats
682 have been extensively revised and improved.
684 For developers, the build system now requires Autoconf 2.60 and
687 Changes from 0.3.0 to 0.4.0:
689 Changes in build dependencies:
691 * The GNU Scientific Library (libgsl), version 1.6 or later, is
694 * libplot from GNU plotutils is optional. Without it, the new
695 graphing features will not work. If you do not have it
696 installed, you must run `configure' with --without-libplot.
698 * libgmp2 is no longer a dependency.
700 Newly implemented commands and statistical features:
702 * EXAMINE, including its graphing features.
704 * FREQUENCIES now supports percentiles.
712 * SORT CASES now sorts stably, that is, two cases with equal sort
713 criteria will be in the same relative order before and after the
716 * T-TEST (re-written).
718 * DATE and USE. These commands are parsed but otherwise ignored,
719 to enhance compatibility with certain command files that invoke
722 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
723 currently have no effect on PSPP output, but their values are
724 written to and read from system files and thus may affect
725 third-party software.
727 * SET EPOCH implemented.
729 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
732 * FILE HANDLE now supports custom tab widths.
734 Long variable names (and other identifiers) are now supported. Up
735 to the first 64 bytes of each identifier is significant. PSPP now
736 reads and writes system files compatible with SPSS version 12.
738 New --algorithm and --syntax command line options allow
739 SPSS-compatible or enhanced modes to be selected.
741 Support for transformation expressions has been rewritten and
742 significantly improved. Refer to the manual for details.
744 Calculation of moments (mean, standard deviation, kurtosis,
745 skewness) has been rewritten and should now be more accurate. In
746 --algorithm=enhanced mode moments may be more accurate than SPSS in
749 Numerous bugs have been fixed, too many to mention here. Many new
750 tests have been added, leading to the discovery and fixing of many
753 The ASCII output driver can now squeeze multiple blank lines into
756 Much of the code has been rewritten and refactored. It is now much
759 The FILE TYPE and REPEATING DATA commands have been disabled for
760 this release because their implementations were deemed too buggy to
761 be useful. They will be fixed and replaced in a future release.
763 New pspp-mode for Emacs (in pspp-mode.el).
765 Added rudimentary command-line completion for interactive input.
767 lib/julcal and lib/dcdflib are no longer used, so they have been
770 For developers, the build system now requires Autoconf 2.58 and
771 Automake 1.7. The included gettext has been updated to version
774 Some reports state that Texinfo 4.8, the latest version, may be
775 necessary to successfully format the documentation on some systems.
777 Version 0.3.0 changes since 0.2.3:
781 * Using alphanumeric variables in functions under AGGREGATE
784 * Under certain circumstances, the final case would be omitted
785 from the results of an AGGREGATE operation. Fixed.
787 * Undefined behavior was invoked by referencing a freed pointer
788 under certain circumstances. Fixed.
790 * A wrong record size was displayed when paging the active file to
793 * Not having enough temporary space for sorting caused a core
796 * Syntax errors in function descriptions on AGGREGATE caused core
799 * A null pointer was dereferenced, causing a core dump, when
800 PERCENTILES was specified on FREQUENCIES. This fixes the
801 problem, but PSPP still doesn't calculate percentiles.
803 * SORT always sorted in ascending order. Fixed.
805 * Some minor memory leaks in the expression parser were removed.
807 * Many assertions fixed for strict ANSI C compliance.
811 * SET ECHO ON now implemented, but turned off by default.
813 * PRINT specifier supported on END REPEAT.
817 * System libgmp2 library is used if installed instead of
818 unconditionally using the included libgmp2 subset.
820 * Extensive code cleanup, which continues.
822 * Added CORRELATIONS command parser, but not implemented.

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

877 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
880 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
881 <BZN-mdksh@t-online.de> for reporting this bug.
883 * MATCH FILES corrupted memory and dumped core on some syntax
886 * MATCH FILES should set numeric values not available to the
887 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
888 <BZN-mdksh@t-online.de> for reporting this bug.
890 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
891 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
895 * Some systems didn't like the way open_file was coded. Thanks to
896 Hankin <hankin@rogue.consultco.com> for pointing this out.
898 * The SAVE procedure didn't save long string variables properly.
899 Fixed by this patch. Thanks to Hankin
900 <hankin@rogue.consultco.com> for this patch.

928 `unused variable' warnings under gcc 2.7.2.3, fixing this will

934 their include path. Thanks to OKUJI Yoshinori
