5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * The NPAR TESTS calculation of significance for the RUNS subcommand
12 * Formatting of SYSFILE INFO output was made easier to read.
14 Changes from 0.8.3 to 0.8.3.1:
16 * Fixed a bug where planned comparisons in oneway anova did not correctly
17 handle negative T-values.
19 Changes from 0.8.2 to 0.8.3:
21 * Independent T-Tests displayed the standard error of the difference
22 and the confidence interval for the unequal variances case, where
23 the equal variances case should have been. This has been fixed.
25 * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
26 intervals for the coefficients to be printed.
28 * When DESCRIPTIVES calculates Z scores, it now omits cases filtered
29 by the current FILTER settings.
31 * PSPPIRE graphical user interface improvements:
33 - Dialog boxes with source variable lists can now choose the sort
34 order; right click and select from the popup menu.
36 - File|Open now allows an encoding to be selected for opening
39 - File|Display Data File Information|External File... now allows an
40 encoding to be selected.
42 - A problem with the Means dialog has been resolved (bug #41433).
44 - Several problems related to the input of spreadsheets have been
45 fixed (bug #41657, #41620
47 * System file related improvements:
49 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
50 pick an encoding for reading a system file that does not identify
53 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
54 character encoding of string data in the system file.
56 - Variable labels over 255 bytes long are now accepted without
57 truncation (bug #41863).
59 - System files that contain duplicate variable names may now be
60 read successfully (bug #41475).
62 Changes from 0.8.1 to 0.8.2:
64 * Charts are now rendered with colours from the Tango palette instead
65 of fully saturated primaries.
67 * Support for new system file variants:
69 - PSPP can now read and write ZCOMPRESSED system files, which
70 compress data much more effectively than older "compressed"
71 files. (The older format is still supported.)
73 - PSPP can now decrypt encrypted system files, using the new
74 pspp-convert utility. The encrypted system file format is
75 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
76 do not directly read or write this format.
78 * Missing values for long string variables are now read from and
79 written to system files in an SPSS-compatible fashion.
81 (Earlier versions of PSPP that supported missing values for long
82 string variables wrote them to system files in an SPSS-incompatible
83 way. To fix the problem, read the system file with this version of
84 PSPP and then save a new copy of it.)
86 * pspp-convert, a new standalone utility for converting SPSS system
87 and portable files to other formats, is now included. The initial
88 version supports comma-separated value files as output format.
89 pspp-convert can also decrypt encrypted system files.
93 - zlib is now a required dependency. (Previously it was optional.)
95 Changes from 0.8.0 to 0.8.1:
101 * Changes to existing commands:
103 - CROSSTABS: The requirement that one expected count must be less than five
104 before Fishers Exact Test will be reported has been removed.
106 * PSPPIRE graphical user interface improvements:
108 - A new set of icons has been contributed.
110 - Syntax windows now parse syntax in "auto" mode, which in practice
111 should mean that both "batch" and "interactive" syntax now works,
112 instead of just "interactive" syntax.
114 - The variable pane of data windows now include a Role column.
118 - System files written by IBM SPSS 21 are now read without warnings.
120 - System files written by "VOXCO INTERVIEWER 4.3" are now read
123 - PSPPIRE should now more gracefully handle syntax files that contain
126 Changes from 0.6.2 to 0.8.0:
132 - DATAFILE ATTRIBUTES
139 - LOGISTIC REGRESSION
143 - PRESERVE and RESTORE
147 - SAVE TRANSLATE to CSV and tab-delimited files
149 - VARIABLE ATTRIBUTES
151 * Changes to existing commands:
153 - AUTORECODE has a new GROUP subcommand.
155 - CROSSTABS has been re-implemented to fix numerous bugs.
157 - EXAMINE: /MISSING=LISTWISE is now the default.
159 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
160 contains an INCLUDE or INSERT command, substitutions are not
161 applied to the included file.
163 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
165 - HOST has been updated to use more modern syntax.
167 - Most commands that work with data files now support a new
170 - MISSING VALUES can now assign missing values to long string
173 - ONEWAY: the POSTHOC subcommand is now implemented.
175 - The following new subcommands to NPAR TESTS have been implemented:
176 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
177 MCNEMAR, SIGN, WILCOXON, and RUNS
179 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
180 DPROMPT subcommands. The defaults are now fixed values.
182 - SHOW now has a JOURNAL subcommand, to show the location of the
185 - VALUE LABELS can now assign value labels to long string
188 * Other language changes:
190 - The new DATASET commands replace the "scratch file" PSPP
191 extension, which is no longer supported.
193 - Strings may now include arbitrary Unicode code points specified
194 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
195 code point U+1D11E, the musical G clef character, may be
196 expressed as U'1D11E'.
198 See the "Tokens" section in the PSPP manual for more information.
200 - In previous versions of PSPP, in a string expressed in
201 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
202 bytes in the locale encoding. In this version of PSPP, X'hh'
203 syntax always expresses bytes in UTF-8 encoding.
205 See the "Tokens" section in the PSPP manual for more information.
207 * PSPPIRE graphical user interface improvements:
209 - Added support for non-ASCII characters in strings, labels and
212 - A "Split Window" function is available, which makes it easier to
213 see different parts of a large data file.
215 - Data files can now be opened by specifing their name as the first
216 argument. This means that on a properly configured desktop, double
217 clicking on an icon will open the file.
219 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
220 via using an "intelligent" application assistant dialog.
224 - The new "cairo" output driver supports output in PostScript, PDF,
225 and SVG formats. Its functionality is a superset of that of the
226 "postscript" driver, which has been removed. You must have Cairo
227 and Pango installed to build the "cairo" driver.
229 - Charts are now produced with Cairo and Pango, instead of libplot.
230 Without them, the new graphing features will not work. If you do
231 not have Cairo and Pango installed, you must run `configure' with
234 - The plain text output driver now properly supports multibyte UTF-8
235 characters, including double-width characters and combining
238 - Output to OpenDocument format is now supported.
240 - The HTML output is much improved.
242 * The "pspp" program has a new option --batch (or -b) that selects
243 "batch" syntax mode. In previous versions of PSPP this syntax mode
244 was the default. Now a new "auto" syntax mode is the default. In
245 "auto" mode, PSPP interprets most syntax files correctly regardless
246 of their intended syntax mode.
248 See the "Syntax Variants" section in the PSPP manual for more
251 * The "pspp" program has a new option --syntax-encoding that
252 specifies the encoding for syntax files listed on the command line,
253 as well as the default encoding for syntax files included with
254 INCLUDE or INSERT. The default is to accept the system locale
255 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
256 one the system file uses.
258 See the documentation for the INSERT command in the PSPP manual for
261 * Text data files that PRINT and WRITE creates now use the system
262 native line ends by default (CRLF on Windows, LF only elsewhere).
263 Use the new ENDS subcommand on FILE HANDLE to override the default.
265 * A new Perl module allows Perl programs to read and write PSPP
268 * A tutorial chapter has been added to the user manual.
270 Changes from 0.6.1 to 0.6.2:
274 - Dutch, thanks to Harry Thijssen.
276 - Brazilian Portuguese, thanks to Michel Boaventura.
278 Thanks for translations are also due to the coordinators at
279 translationproject.org.
281 * Statistical bug fixes:
283 - REGRESSION: Report correct standard error of the estimate (bug
286 - T-TEST: Report correct significance of paired sample T-test in
287 the common case (bug #26936) and corner cases. Thanks to Mike
288 Griffiths and Matej Cepl for reporting these bugs.
290 * Build fixes and changes:
292 - Fix build with GTK+ 2.17.4 and later.
294 - Make running "make" after running "configure" with different
295 settings reliably rebuild version.c.
297 - Cygwin and MinGW build fixes.
299 - Fixes for building with recent gnulib.
301 - The Makefile now honors two new variables, PSPP_LDFLAGS and
302 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
303 binaries, respectively. This makes building easier for some
306 - Fixes for "configure --enable-relocatable" (bug #25508).
308 * Data file bug fixes and changes:
310 - Fix reading text data files that contain a mix of white space
311 and commas. Now "a ,b" is treated as two fields containing "a"
312 and "b"; previously it was treated as three, with an empty field
315 - Fix writing corrupted .sav files on Windows.
317 - Fix writing variable labels longer than 252 bytes to save files.
318 Thanks to Robert Westlund for reporting this bug.
320 - Fix writing corrupted .por files (bug #26034).
322 - Fix reading .por files whose initial lines are not padded out
323 with spaces as expected.
325 - PSPP will no longer issue warnings about some .sav file records
326 or values that it does not understand. These warnings were
327 harmless, but needlessly alarmed some users.
329 - Fix crash reading empty string fields from PostgreSQL databases.
331 * Bug fixes that affect PSPP and PSPPIRE:
333 - Users may now control precision of output statistics. Instead
334 of hard coding the width and decimals of output numbers, respect
335 the default format in most instances. Counts are now normally
336 displayed with the format of the weight variable, if any.
338 - Fix crash when an INSERT command specifies the name of a file
339 that does not exist (bug #24569).
341 - Fix crash when CROSSTABS specifies a long-string variable (bugs
344 - Fix crash drawing pie charts with many segments.
346 - Fix crash when NUMERIC specifies an invalid format.
348 * PSPPIRE bug fixes and changes:
350 - On Windows, write the output file to the user's home directory
351 instead of the current directory, to better match user
354 - Some data editor fixes.
358 - Fix typo in BINOMIAL section of user manual (bug #25892).
360 Changes from 0.6.0 to 0.6.1:
362 * Statistical bug fixes:
364 - Report correct standardized regression coefficients in linear
365 regression output (bug #23567).
367 * Bug fixes that affect PSPP and PSPPIRE:
369 - Avoid crash with pie charts (bug #24014).
371 - Don't append % to count totals (bug #24003).
373 - Don't crash on bad input (bug #24031).
375 - Don't crash if "end data." is not left aligned (bug #24115).
377 - Change default workspace value to 64 MB, to avoid unnecessary
378 disk accesses on modern machines.
382 - Add ".sav" or ".por" suffix to filename when saving with Save_As
385 - Make it possible to reopen the output window on Windows (bug
388 - A POSIX regular expression library is now included and used
389 automatically if the host does not have one or has one that is
392 * Build fixes and changes:
394 - Work around bug in GSL that prevented build with recent GCC
395 versions without manually adding -fgnu89-inline to CFLAGS.
397 - Also warn about missing prerequisites as we encounter them (bug
400 - Distribute necessary files to allow users working from the
401 distributed tarball to configure with --enable-gui-tools.
403 - Append $(EXEEXT_FOR_BUILD) to output file name when building
404 q2c, fixing build problems on Windows.
406 - GSL 1.8 or later is now required.
408 - Build errors with --enable-relocatable were fixed.
410 * The German translations were removed, since native German speakers
411 found them too poor to be useful.
413 Changes from 0.4.0 to 0.6.0:
415 * The PSPP license is now version 3 or later of the GNU General
416 Public License. Previously, it was version 2 or later.
418 * PSPP now has a graphical interface, called PSPPIRE. This
419 interface allows you to enter data and variable definitions
420 interactively. Commands may be executed in syntax form, or by
421 using the interactive dialog boxes available from the dropdown
424 * A few sample syntax files are now included in the `examples'
427 * Numerous major and minor bugs have been fixed.
431 * The INSTALL file now reflects the details of how to install
432 PSPP. It is a tailored version of the generic installation
433 instructions, instead of a verbatim copy.
435 * iconv, which is ordinarily installed as part of a Unix-like
436 system, is now required. If you don't have it already, you can
437 install GNU libiconv (http://www.gnu.org/software/libiconv/).
439 * libxml2 and zlib are new optional dependencies. They are
440 required to use PSPP's support for reading Gnumeric files.
442 Statistical procedure changes:
444 * REGRESSION is a new procedure for fitting linear models to data
445 via least-squares estimation.
447 * NPAR TESTS is a new procedure for non-parametric tests. In this
448 release, it supports binomial and chi-square tests.
450 * RANK is a new procedure to rank variables. It supports numerous
453 * FREQUENCIES can now output histograms and pie charts. These
454 features were present in earlier releases, but not documented.
456 User interface changes:
458 * In many situations where PSPP once terminated with a fatal
459 error, PSPP now recovers and continues execution.
461 * PSPP is now able to start up and run even if it cannot find its
464 * Journaling of interactive commands to a disk file is now
465 implemented. By default, journaling is enabled, to a file named
466 `pspp.jnl' in the current directory. SET JOURNAL may be used to
469 * The use of `+' between syntax file names on the command line to
470 prevent the dictionary from being cleared between their
471 executions is no longer supported. All syntax files are now
472 executed as if `+' had been specified.
474 * The -d/--define and -u/--undef command line options are no
475 longer supported. Instead, use /usr/bin/env or shell primitives
476 to define or clear environment variables before invoking PSPP.
478 * If a syntax file named named `rc' is found in a configuration
479 directory (such as $HOME/.pspp), it is executed before any
480 syntax file specified on the command line. The -r or
481 --no-statrc command line option may be used to disable this
486 * Output configuration options have changed. Please refer to the
487 manual for a full description of the available options.
489 In consequence, you will need to reinstall your "devices" file.
490 "make install" will do this for you.
492 * Most error messages are now written to PSPP output files by
493 default. SET ERROR can be used to disable this behavior.
495 * When invoked interactively, PSPP now by default produces output
496 on the terminal, piping it through the "more" program.
497 Previously, by default output was written only to file
498 pspp.list. On most terminals, the page length used for output
499 automatically adapts to the terminal size, even if the terminal
504 - This driver now supports charts in output. Charts are written
505 as separate files that the main output file refers to. By
506 default, charts are written in PNG format to files named
507 pspp-1.png, pspp-2.png, and so on.
509 - Configurations are provided that use VT100 (and xterm)
510 line-drawing characters in tables. The option "-o list-vt100"
511 requests use of this device for output to pspp.list.
515 - The default paper size is now determined using the PAPERSIZE
516 environment variable, or the LC_PAPER locale category on
517 systems that support it. If these are not set, the default is
518 now A4, instead of US letter. To make US letter the default,
519 set PAPERSIZE to "letter" in your environment.
521 - Font metrics are now read from AFM files, instead of
522 Groff-format metrics files. PostScript fonts can now be
525 In consequence, you will need to install an AFM file for each
526 font used in PostScript output. "make install" will install
527 AFM files for the standard PostScript fonts, including the
528 ones that the PostScript driver uses by default.
530 - Standard paper sizes no longer need to be specified through a
531 configuration file. The "papersize" configuration file is no
532 longer needed, or supported.
534 - The PostScript prologue is no longer obtained from the
535 "ps-prologue" configuration file. This configuration file is
536 no longer needed, or supported.
540 - The HTML prologue is no longer obtained from the
541 "html-prologue" configuration file. This configuration file
542 is no longer needed, or supported.
544 Command language changes:
546 * The following commands are new:
548 - GET DATA, which currently supports reading Gnumeric files and
549 text data files. It will be extended later to read other
550 types of foreign data.
552 - CD, to change the current directory.
554 - INSERT, to execute a syntax file.
556 - DELETE VARIABLES, to remove variables from the active file
559 - ADD DOCUMENT, to add text to active file documents.
561 - CLOSE FILE HANDLE (a PSPP extension; see below).
563 - XEXPORT, a PSPP extension that is a transformation equivalent
566 * The following functions for transformation expressions are new:
568 - DATEDIFF, for computing the difference of two dates.
570 - DATESUM, for advancing a date by a specified duration.
572 - VALUELABEL, to obtain the value label for a value.
574 * PSPP now supports very long string variables (over 255 bytes
577 * MATCH FILES now supports the FIRST and LAST subcommands.
579 * Previous versions of PSPP prohibited using commands to both read and
580 write a single file at the same time. Now, PSPP allows this, and
581 the new version of the file atomically replaces the old version.
583 * The following commands are no longer available. They will be
584 re-implemented in a later release:
586 - CLEAR TRANSFORMATIONS
592 * The PROCESS IF command, which was deprecated, has been removed.
593 You may replace any usage of it by SELECT IF following
594 TEMPORARY, which has the same effect.
596 * The output format for variables created by VECTOR may now be
597 specified as part of the VECTOR syntax.
599 "Scratch files", a new PSPP extension:
601 A scratch file, like a system file, consists of a dictionary and
602 any number of cases. Small scratch files are stored in memory;
603 one that grows too large is written to disk. By default, any file
604 handle whose name begins with # is assumed to refer to a scratch
607 Scratch files can be used just about anywhere a system or portable
608 file can be used. Also, portable files are now allowed in most
609 places that system files were allowed in previous PSPP version.
611 A new CLOSE FILE HANDLE command allows the storage associated with
612 scratch files to be freed. It also allows file handles to be
613 reassigned to new files.
615 For more information on scratch files, refer to the "File Handles"
616 section in the PSPP manual. For specifics of what commands now
617 allow what kinds of files to be specified, refer to the
618 documentation on those particular commands.
622 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
623 translation, are now supported. Use FILE HANDLE to specify the
624 format of these files.
626 * Little-endian, big-endian, and VAX-endian formats are now
627 supported for integer binary formats when reading and writing
628 data files. The new RIB and WIB subcommands on the SET command
629 control endianness of integer data. The default is the host's
632 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
633 floating point binary formats when reading and writing data
634 files. The new RRB and WRB subcommands on the SET command
635 control the floating point format. The default is the host's
636 native floating point format.
638 * DATA LIST now supports the SKIP subcommand, to skip records at
639 the beginning of a file. For compatibility, DATA LIST now
640 treats N format as F format for FREE and LIST format input.
642 * The SAVE and XSAVE commands now support the UNSELECTED,
643 PERMISSIONS, NAMES, and MAP subcommands.
645 * The EXPORT command has been re-implemented to obtain better
646 results. Support for the UNSELECTED, DIGITS, and TYPE
647 subcommands has been added.
649 * For compatibility, PRINT now inserts a space at the beginning of
650 every output line, even lines that would otherwise be blank,
651 when OUTFILE is specified. (The behavior of WRITE is
654 * For compatibility, PRINT EJECT now inserts the digit `1' at the
655 beginning of each line that should begin a new page.
657 * For compatibility, WRITE now outputs the system-missing value as
658 a field filled with spaces. Binary formats are an exception.
659 (The behavior of PRINT is unchanged.)
663 * Input and output format descriptions have been rewritten. They
664 now precisely describe what is accepted on input and written on
667 * The descriptions of the PSPP system and portable file formats
668 have been extensively revised and improved.
670 For developers, the build system now requires Autoconf 2.60 and
673 Changes from 0.3.0 to 0.4.0:
675 Changes in build dependencies:
677 * The GNU Scientific Library (libgsl), version 1.6 or later, is
680 * libplot from GNU plotutils is optional. Without it, the new
681 graphing features will not work. If you do not have it
682 installed, you must run `configure' with --without-libplot.
684 * libgmp2 is no longer a dependency.
686 Newly implemented commands and statistical features:
688 * EXAMINE, including its graphing features.
690 * FREQUENCIES now supports percentiles.
698 * SORT CASES now sorts stably, that is, two cases with equal sort
699 criteria will be in the same relative order before and after the
702 * T-TEST (re-written).
704 * DATE and USE. These commands are parsed but otherwise ignored,
705 to enhance compatibility with certain command files that invoke
708 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
709 currently have no effect on PSPP output, but their values are
710 written to and read from system files and thus may affect
711 third-party software.
713 * SET EPOCH implemented.
715 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
718 * FILE HANDLE now supports custom tab widths.
720 Long variable names (and other identifiers) are now supported. Up
721 to the first 64 bytes of each identifier is significant. PSPP now
722 reads and writes system files compatible with SPSS version 12.
724 New --algorithm and --syntax command line options allow
725 SPSS-compatible or enhanced modes to be selected.
727 Support for transformation expressions has been rewritten and
728 significantly improved. Refer to the manual for details.
730 Calculation of moments (mean, standard deviation, kurtosis,
731 skewness) has been rewritten and should now be more accurate. In
732 --algorithm=enhanced mode moments may be more accurate than SPSS in
735 Numerous bugs have been fixed, too many to mention here. Many new
736 tests have been added, leading to the discovery and fixing of many
739 The ASCII output driver can now squeeze multiple blank lines into
742 Much of the code has been rewritten and refactored. It is now much
745 The FILE TYPE and REPEATING DATA commands have been disabled for
746 this release because their implementations were deemed too buggy to
747 be useful. They will be fixed and replaced in a future release.
749 New pspp-mode for Emacs (in pspp-mode.el).
751 Added rudimentary command-line completion for interactive input.
753 lib/julcal and lib/dcdflib are no longer used, so they have been
756 For developers, the build system now requires Autoconf 2.58 and
757 Automake 1.7. The included gettext has been updated to version
760 Some reports state that Texinfo 4.8, the latest version, may be
761 necessary to successfully format the documentation on some systems.
763 Version 0.3.0 changes since 0.2.3:
767 * Using alphanumeric variables in functions under AGGREGATE
770 * Under certain circumstances, the final case would be omitted
771 from the results of an AGGREGATE operation. Fixed.
773 * Undefined behavior was invoked by referencing a freed pointer
774 under certain circumstances. Fixed.
776 * A wrong record size was displayed when paging the active file to
779 * Not having enough temporary space for sorting caused a core
782 * Syntax errors in function descriptions on AGGREGATE caused core
785 * A null pointer was dereferenced, causing a core dump, when
786 PERCENTILES was specified on FREQUENCIES. This fixes the
787 problem, but PSPP still doesn't calculate percentiles.
789 * SORT always sorted in ascending order. Fixed.
791 * Some minor memory leaks in the expression parser were removed.
793 * Many assertions fixed for strict ANSI C compliance.
797 * SET ECHO ON now implemented, but turned off by default.
799 * PRINT specifier supported on END REPEAT.
803 * System libgmp2 library is used if installed instead of
804 unconditionally using the included libgmp2 subset.
806 * Extensive code cleanup, which continues.
808 * Added CORRELATIONS command parser, but not implemented.
810 Version 0.2.3 changes since 0.2.2:
814 * SPLIT FILE with a string variable caused a core dump. Fixed.
816 * Nested INCLUDEs didn't work. Fixed.
818 * The MATCH FILES procedure set the values of variables not present
819 to 0. It should have been SYSMIS. This is now fixed.
821 * The REMARK command was too aggressive about skipping lines. It
822 didn't like being the last command in a file.
824 * Comment parsing wasn't consistent with the rest of the code in its
825 idea of where one command ends and another starts. This meant
826 that sometimes commands would be mysteriously ignored. Thanks to
827 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
829 * The TABLE subcommand on MATCH FILES worked only erratically at
830 best. This fixes it. Thanks to Dr. Dirk Melcher
831 <BZN-mdksh@t-online.de> for reporting this bug.
833 * VARIABLE LABELS rejected a slash before the first variable
834 specification, contradicting the documentation. Thanks to Walter
835 M. Gray <graywm@northernc.on.ca> for reporting this bug.
837 * Because of an incorrect optimization in memory allocation,
838 CROSSTABS sometimes segfaulted when asked to output multiple
839 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
842 * CROSSTABS didn't display value labels for column and row
843 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
846 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
847 <BZN-mdksh@t-online.de> for reporting this bug.

866 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
867 <BZN-mdksh@t-online.de> for reporting this bug.
869 * MATCH FILES corrupted memory and dumped core on some syntax
872 * MATCH FILES should set numeric values not available to the
873 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
874 <BZN-mdksh@t-online.de> for reporting this bug.
876 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
