5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
7 Changes from 0.8.3 to 0.8.4:
9 * Formatting of SYSFILE INFO output was made easier to read.
11 * Bug fixes, including the following notable ones:
13 - FREQUENCIES works properly for string variables. (This bug was
16 - CROSSTABS now correctly computes all of the measures that it
17 offers. Some measures have been removed because they were not
20 - The NPAR TESTS calculation of significance for the RUNS
21 subcommand has been corrected.
23 - Planned comparisons in ONEWAY ANOVA now correctly handle negative
26 - Conformance fixes to Open Document output format.
28 Changes from 0.8.2 to 0.8.3:
30 * Independent T-Tests displayed the standard error of the difference
31 and the confidence interval for the unequal variances case, where
32 the equal variances case should have been. This has been fixed.
34 * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
35 intervals for the coefficients to be printed.
37 * When DESCRIPTIVES calculates Z scores, it now omits cases filtered
38 by the current FILTER settings.
40 * PSPPIRE graphical user interface improvements:
42 - Dialog boxes with source variable lists can now choose the sort
43 order; right click and select from the popup menu.
45 - File|Open now allows an encoding to be selected for opening
48 - File|Display Data File Information|External File... now allows an
49 encoding to be selected.
51 - A problem with the Means dialog has been resolved (bug #41433).
53 - Several problems related to the input of spreadsheets have been
54 fixed (bug #41657, #41620
56 * System file related improvements:
58 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
59 pick an encoding for reading a system file that does not identify
62 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
63 character encoding of string data in the system file.
65 - Variable labels over 255 bytes long are now accepted without
66 truncation (bug #41863).
68 - System files that contain duplicate variable names may now be
69 read successfully (bug #41475).
71 Changes from 0.8.1 to 0.8.2:
73 * Charts are now rendered with colours from the Tango palette instead
74 of fully saturated primaries.
76 * Support for new system file variants:
78 - PSPP can now read and write ZCOMPRESSED system files, which
79 compress data much more effectively than older "compressed"
80 files. (The older format is still supported.)
82 - PSPP can now decrypt encrypted system files, using the new
83 pspp-convert utility. The encrypted system file format is
84 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
85 do not directly read or write this format.
87 * Missing values for long string variables are now read from and
88 written to system files in an SPSS-compatible fashion.
90 (Earlier versions of PSPP that supported missing values for long
91 string variables wrote them to system files in an SPSS-incompatible
92 way. To fix the problem, read the system file with this version of
93 PSPP and then save a new copy of it.)
95 * pspp-convert, a new standalone utility for converting SPSS system
96 and portable files to other formats, is now included. The initial
97 version supports comma-separated value files as output format.
98 pspp-convert can also decrypt encrypted system files.
102 - zlib is now a required dependency. (Previously it was optional.)
104 Changes from 0.8.0 to 0.8.1:
110 * Changes to existing commands:
112 - CROSSTABS: The requirement that one expected count must be less than five
113 before Fishers Exact Test will be reported has been removed.
115 * PSPPIRE graphical user interface improvements:
117 - A new set of icons has been contributed.
119 - Syntax windows now parse syntax in "auto" mode, which in practice
120 should mean that both "batch" and "interactive" syntax now works,
121 instead of just "interactive" syntax.
123 - The variable pane of data windows now include a Role column.
127 - System files written by IBM SPSS 21 are now read without warnings.
129 - System files written by "VOXCO INTERVIEWER 4.3" are now read
132 - PSPPIRE should now more gracefully handle syntax files that contain
135 Changes from 0.6.2 to 0.8.0:
141 - DATAFILE ATTRIBUTES
148 - LOGISTIC REGRESSION
152 - PRESERVE and RESTORE
156 - SAVE TRANSLATE to CSV and tab-delimited files
158 - VARIABLE ATTRIBUTES
160 * Changes to existing commands:
162 - AUTORECODE has a new GROUP subcommand.
164 - CROSSTABS has been re-implemented to fix numerous bugs.
166 - EXAMINE: /MISSING=LISTWISE is now the default.
168 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
169 contains an INCLUDE or INSERT command, substitutions are not
170 applied to the included file.
172 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
174 - HOST has been updated to use more modern syntax.
176 - Most commands that work with data files now support a new
179 - MISSING VALUES can now assign missing values to long string
182 - ONEWAY: the POSTHOC subcommand is now implemented.
184 - The following new subcommands to NPAR TESTS have been implemented:
185 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
186 MCNEMAR, SIGN, WILCOXON, and RUNS
188 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
189 DPROMPT subcommands. The defaults are now fixed values.
191 - SHOW now has a JOURNAL subcommand, to show the location of the
194 - VALUE LABELS can now assign value labels to long string
197 * Other language changes:
199 - The new DATASET commands replace the "scratch file" PSPP
200 extension, which is no longer supported.
202 - Strings may now include arbitrary Unicode code points specified
203 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
204 code point U+1D11E, the musical G clef character, may be
205 expressed as U'1D11E'.
207 See the "Tokens" section in the PSPP manual for more information.
209 - In previous versions of PSPP, in a string expressed in
210 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
211 bytes in the locale encoding. In this version of PSPP, X'hh'
212 syntax always expresses bytes in UTF-8 encoding.
214 See the "Tokens" section in the PSPP manual for more information.
216 * PSPPIRE graphical user interface improvements:
218 - Added support for non-ASCII characters in strings, labels and
221 - A "Split Window" function is available, which makes it easier to
222 see different parts of a large data file.
224 - Data files can now be opened by specifing their name as the first
225 argument. This means that on a properly configured desktop, double
226 clicking on an icon will open the file.
228 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
229 via using an "intelligent" application assistant dialog.
233 - The new "cairo" output driver supports output in PostScript, PDF,
234 and SVG formats. Its functionality is a superset of that of the
235 "postscript" driver, which has been removed. You must have Cairo
236 and Pango installed to build the "cairo" driver.
238 - Charts are now produced with Cairo and Pango, instead of libplot.
239 Without them, the new graphing features will not work. If you do
240 not have Cairo and Pango installed, you must run `configure' with
243 - The plain text output driver now properly supports multibyte UTF-8
244 characters, including double-width characters and combining
247 - Output to OpenDocument format is now supported.
249 - The HTML output is much improved.
251 * The "pspp" program has a new option --batch (or -b) that selects
252 "batch" syntax mode. In previous versions of PSPP this syntax mode
253 was the default. Now a new "auto" syntax mode is the default. In
254 "auto" mode, PSPP interprets most syntax files correctly regardless
255 of their intended syntax mode.
257 See the "Syntax Variants" section in the PSPP manual for more
260 * The "pspp" program has a new option --syntax-encoding that
261 specifies the encoding for syntax files listed on the command line,
262 as well as the default encoding for syntax files included with
263 INCLUDE or INSERT. The default is to accept the system locale
264 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
265 one the system file uses.
267 See the documentation for the INSERT command in the PSPP manual for
270 * Text data files that PRINT and WRITE creates now use the system
271 native line ends by default (CRLF on Windows, LF only elsewhere).
272 Use the new ENDS subcommand on FILE HANDLE to override the default.
274 * A new Perl module allows Perl programs to read and write PSPP
277 * A tutorial chapter has been added to the user manual.
279 Changes from 0.6.1 to 0.6.2:
283 - Dutch, thanks to Harry Thijssen.
285 - Brazilian Portuguese, thanks to Michel Boaventura.
287 Thanks for translations are also due to the coordinators at
288 translationproject.org.
290 * Statistical bug fixes:
292 - REGRESSION: Report correct standard error of the estimate (bug
295 - T-TEST: Report correct significance of paired sample T-test in
296 the common case (bug #26936) and corner cases. Thanks to Mike
297 Griffiths and Matej Cepl for reporting these bugs.
299 * Build fixes and changes:
301 - Fix build with GTK+ 2.17.4 and later.
303 - Make running "make" after running "configure" with different
304 settings reliably rebuild version.c.
306 - Cygwin and MinGW build fixes.
308 - Fixes for building with recent gnulib.
310 - The Makefile now honors two new variables, PSPP_LDFLAGS and
311 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
312 binaries, respectively. This makes building easier for some
315 - Fixes for "configure --enable-relocatable" (bug #25508).
317 * Data file bug fixes and changes:
319 - Fix reading text data files that contain a mix of white space
320 and commas. Now "a ,b" is treated as two fields containing "a"
321 and "b"; previously it was treated as three, with an empty field
324 - Fix writing corrupted .sav files on Windows.
326 - Fix writing variable labels longer than 252 bytes to save files.
327 Thanks to Robert Westlund for reporting this bug.
329 - Fix writing corrupted .por files (bug #26034).
331 - Fix reading .por files whose initial lines are not padded out
332 with spaces as expected.
334 - PSPP will no longer issue warnings about some .sav file records
335 or values that it does not understand. These warnings were
336 harmless, but needlessly alarmed some users.
338 - Fix crash reading empty string fields from PostgreSQL databases.
340 * Bug fixes that affect PSPP and PSPPIRE:
342 - Users may now control precision of output statistics. Instead
343 of hard coding the width and decimals of output numbers, respect
344 the default format in most instances. Counts are now normally
345 displayed with the format of the weight variable, if any.
347 - Fix crash when an INSERT command specifies the name of a file
348 that does not exist (bug #24569).
350 - Fix crash when CROSSTABS specifies a long-string variable (bugs
353 - Fix crash drawing pie charts with many segments.
355 - Fix crash when NUMERIC specifies an invalid format.
357 * PSPPIRE bug fixes and changes:
359 - On Windows, write the output file to the user's home directory
360 instead of the current directory, to better match user
363 - Some data editor fixes.
367 - Fix typo in BINOMIAL section of user manual (bug #25892).
369 Changes from 0.6.0 to 0.6.1:
371 * Statistical bug fixes:
373 - Report correct standardized regression coefficients in linear
374 regression output (bug #23567).
376 * Bug fixes that affect PSPP and PSPPIRE:
378 - Avoid crash with pie charts (bug #24014).
380 - Don't append % to count totals (bug #24003).
382 - Don't crash on bad input (bug #24031).
384 - Don't crash if "end data." is not left aligned (bug #24115).
386 - Change default workspace value to 64 MB, to avoid unnecessary
387 disk accesses on modern machines.
391 - Add ".sav" or ".por" suffix to filename when saving with Save_As
394 - Make it possible to reopen the output window on Windows (bug
397 - A POSIX regular expression library is now included and used
398 automatically if the host does not have one or has one that is
401 * Build fixes and changes:
403 - Work around bug in GSL that prevented build with recent GCC
404 versions without manually adding -fgnu89-inline to CFLAGS.
406 - Also warn about missing prerequisites as we encounter them (bug
409 - Distribute necessary files to allow users working from the
410 distributed tarball to configure with --enable-gui-tools.
412 - Append $(EXEEXT_FOR_BUILD) to output file name when building
413 q2c, fixing build problems on Windows.
415 - GSL 1.8 or later is now required.
417 - Build errors with --enable-relocatable were fixed.
419 * The German translations were removed, since native German speakers
420 found them too poor to be useful.
422 Changes from 0.4.0 to 0.6.0:
424 * The PSPP license is now version 3 or later of the GNU General
425 Public License. Previously, it was version 2 or later.
427 * PSPP now has a graphical interface, called PSPPIRE. This
428 interface allows you to enter data and variable definitions
429 interactively. Commands may be executed in syntax form, or by
430 using the interactive dialog boxes available from the dropdown
433 * A few sample syntax files are now included in the `examples'
436 * Numerous major and minor bugs have been fixed.
440 * The INSTALL file now reflects the details of how to install
441 PSPP. It is a tailored version of the generic installation
442 instructions, instead of a verbatim copy.
444 * iconv, which is ordinarily installed as part of a Unix-like
445 system, is now required. If you don't have it already, you can
446 install GNU libiconv (http://www.gnu.org/software/libiconv/).
448 * libxml2 and zlib are new optional dependencies. They are
449 required to use PSPP's support for reading Gnumeric files.
451 Statistical procedure changes:
453 * REGRESSION is a new procedure for fitting linear models to data
454 via least-squares estimation.
456 * NPAR TESTS is a new procedure for non-parametric tests. In this
457 release, it supports binomial and chi-square tests.
459 * RANK is a new procedure to rank variables. It supports numerous
462 * FREQUENCIES can now output histograms and pie charts. These
463 features were present in earlier releases, but not documented.
465 User interface changes:
467 * In many situations where PSPP once terminated with a fatal
468 error, PSPP now recovers and continues execution.
470 * PSPP is now able to start up and run even if it cannot find its
473 * Journaling of interactive commands to a disk file is now
474 implemented. By default, journaling is enabled, to a file named
475 `pspp.jnl' in the current directory. SET JOURNAL may be used to
478 * The use of `+' between syntax file names on the command line to
479 prevent the dictionary from being cleared between their
480 executions is no longer supported. All syntax files are now
481 executed as if `+' had been specified.
483 * The -d/--define and -u/--undef command line options are no
484 longer supported. Instead, use /usr/bin/env or shell primitives
485 to define or clear environment variables before invoking PSPP.
487 * If a syntax file named named `rc' is found in a configuration
488 directory (such as $HOME/.pspp), it is executed before any
489 syntax file specified on the command line. The -r or
490 --no-statrc command line option may be used to disable this
495 * Output configuration options have changed. Please refer to the
496 manual for a full description of the available options.
498 In consequence, you will need to reinstall your "devices" file.
499 "make install" will do this for you.
501 * Most error messages are now written to PSPP output files by
502 default. SET ERROR can be used to disable this behavior.
504 * When invoked interactively, PSPP now by default produces output
505 on the terminal, piping it through the "more" program.
506 Previously, by default output was written only to file
507 pspp.list. On most terminals, the page length used for output
508 automatically adapts to the terminal size, even if the terminal
513 - This driver now supports charts in output. Charts are written
514 as separate files that the main output file refers to. By
515 default, charts are written in PNG format to files named
516 pspp-1.png, pspp-2.png, and so on.
518 - Configurations are provided that use VT100 (and xterm)
519 line-drawing characters in tables. The option "-o list-vt100"
520 requests use of this device for output to pspp.list.
524 - The default paper size is now determined using the PAPERSIZE
525 environment variable, or the LC_PAPER locale category on
526 systems that support it. If these are not set, the default is
527 now A4, instead of US letter. To make US letter the default,
528 set PAPERSIZE to "letter" in your environment.
530 - Font metrics are now read from AFM files, instead of
531 Groff-format metrics files. PostScript fonts can now be
534 In consequence, you will need to install an AFM file for each
535 font used in PostScript output. "make install" will install
536 AFM files for the standard PostScript fonts, including the
537 ones that the PostScript driver uses by default.
539 - Standard paper sizes no longer need to be specified through a
540 configuration file. The "papersize" configuration file is no
541 longer needed, or supported.
543 - The PostScript prologue is no longer obtained from the
544 "ps-prologue" configuration file. This configuration file is
545 no longer needed, or supported.
549 - The HTML prologue is no longer obtained from the
550 "html-prologue" configuration file. This configuration file
551 is no longer needed, or supported.
553 Command language changes:
555 * The following commands are new:
557 - GET DATA, which currently supports reading Gnumeric files and
558 text data files. It will be extended later to read other
559 types of foreign data.
561 - CD, to change the current directory.
563 - INSERT, to execute a syntax file.
565 - DELETE VARIABLES, to remove variables from the active file
568 - ADD DOCUMENT, to add text to active file documents.
570 - CLOSE FILE HANDLE (a PSPP extension; see below).
572 - XEXPORT, a PSPP extension that is a transformation equivalent
575 * The following functions for transformation expressions are new:
577 - DATEDIFF, for computing the difference of two dates.
579 - DATESUM, for advancing a date by a specified duration.
581 - VALUELABEL, to obtain the value label for a value.
583 * PSPP now supports very long string variables (over 255 bytes
586 * MATCH FILES now supports the FIRST and LAST subcommands.
588 * Previous versions of PSPP prohibited using commands to both read and
589 write a single file at the same time. Now, PSPP allows this, and
590 the new version of the file atomically replaces the old version.
592 * The following commands are no longer available. They will be
593 re-implemented in a later release:
595 - CLEAR TRANSFORMATIONS
601 * The PROCESS IF command, which was deprecated, has been removed.
602 You may replace any usage of it by SELECT IF following
603 TEMPORARY, which has the same effect.
605 * The output format for variables created by VECTOR may now be
606 specified as part of the VECTOR syntax.
608 "Scratch files", a new PSPP extension:
610 A scratch file, like a system file, consists of a dictionary and
611 any number of cases. Small scratch files are stored in memory;
612 one that grows too large is written to disk. By default, any file
613 handle whose name begins with # is assumed to refer to a scratch
616 Scratch files can be used just about anywhere a system or portable
617 file can be used. Also, portable files are now allowed in most
618 places that system files were allowed in previous PSPP version.
620 A new CLOSE FILE HANDLE command allows the storage associated with
621 scratch files to be freed. It also allows file handles to be
622 reassigned to new files.
624 For more information on scratch files, refer to the "File Handles"
625 section in the PSPP manual. For specifics of what commands now
626 allow what kinds of files to be specified, refer to the
627 documentation on those particular commands.
631 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
632 translation, are now supported. Use FILE HANDLE to specify the
633 format of these files.
635 * Little-endian, big-endian, and VAX-endian formats are now
636 supported for integer binary formats when reading and writing
637 data files. The new RIB and WIB subcommands on the SET command
638 control endianness of integer data. The default is the host's
641 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
642 floating point binary formats when reading and writing data
643 files. The new RRB and WRB subcommands on the SET command
644 control the floating point format. The default is the host's
645 native floating point format.
647 * DATA LIST now supports the SKIP subcommand, to skip records at
648 the beginning of a file. For compatibility, DATA LIST now
649 treats N format as F format for FREE and LIST format input.
651 * The SAVE and XSAVE commands now support the UNSELECTED,
652 PERMISSIONS, NAMES, and MAP subcommands.
654 * The EXPORT command has been re-implemented to obtain better
655 results. Support for the UNSELECTED, DIGITS, and TYPE
656 subcommands has been added.
658 * For compatibility, PRINT now inserts a space at the beginning of
659 every output line, even lines that would otherwise be blank,
660 when OUTFILE is specified. (The behavior of WRITE is
663 * For compatibility, PRINT EJECT now inserts the digit `1' at the
664 beginning of each line that should begin a new page.
666 * For compatibility, WRITE now outputs the system-missing value as
667 a field filled with spaces. Binary formats are an exception.
668 (The behavior of PRINT is unchanged.)
672 * Input and output format descriptions have been rewritten. They
673 now precisely describe what is accepted on input and written on
676 * The descriptions of the PSPP system and portable file formats
677 have been extensively revised and improved.
679 For developers, the build system now requires Autoconf 2.60 and
682 Changes from 0.3.0 to 0.4.0:
684 Changes in build dependencies:
686 * The GNU Scientific Library (libgsl), version 1.6 or later, is
689 * libplot from GNU plotutils is optional. Without it, the new
690 graphing features will not work. If you do not have it
691 installed, you must run `configure' with --without-libplot.
693 * libgmp2 is no longer a dependency.
695 Newly implemented commands and statistical features:
697 * EXAMINE, including its graphing features.
699 * FREQUENCIES now supports percentiles.
707 * SORT CASES now sorts stably, that is, two cases with equal sort
708 criteria will be in the same relative order before and after the
711 * T-TEST (re-written).
713 * DATE and USE. These commands are parsed but otherwise ignored,
714 to enhance compatibility with certain command files that invoke
717 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
718 currently have no effect on PSPP output, but their values are
719 written to and read from system files and thus may affect
720 third-party software.
722 * SET EPOCH implemented.
724 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
727 * FILE HANDLE now supports custom tab widths.
729 Long variable names (and other identifiers) are now supported. Up
730 to the first 64 bytes of each identifier is significant. PSPP now
731 reads and writes system files compatible with SPSS version 12.
733 New --algorithm and --syntax command line options allow
734 SPSS-compatible or enhanced modes to be selected.
736 Support for transformation expressions has been rewritten and
737 significantly improved. Refer to the manual for details.
739 Calculation of moments (mean, standard deviation, kurtosis,
740 skewness) has been rewritten and should now be more accurate. In
741 --algorithm=enhanced mode moments may be more accurate than SPSS in
744 Numerous bugs have been fixed, too many to mention here. Many new
745 tests have been added, leading to the discovery and fixing of many
748 The ASCII output driver can now squeeze multiple blank lines into
751 Much of the code has been rewritten and refactored. It is now much
754 The FILE TYPE and REPEATING DATA commands have been disabled for
755 this release because their implementations were deemed too buggy to
756 be useful. They will be fixed and replaced in a future release.
758 New pspp-mode for Emacs (in pspp-mode.el).
760 Added rudimentary command-line completion for interactive input.
762 lib/julcal and lib/dcdflib are no longer used, so they have been
765 For developers, the build system now requires Autoconf 2.58 and
766 Automake 1.7. The included gettext has been updated to version
769 Some reports state that Texinfo 4.8, the latest version, may be
770 necessary to successfully format the documentation on some systems.
772 Version 0.3.0 changes since 0.2.3:
776 * Using alphanumeric variables in functions under AGGREGATE
779 * Under certain circumstances, the final case would be omitted
780 from the results of an AGGREGATE operation. Fixed.
782 * Undefined behavior was invoked by referencing a freed pointer
783 under certain circumstances. Fixed.
785 * A wrong record size was displayed when paging the active file to
788 * Not having enough temporary space for sorting caused a core
791 * Syntax errors in function descriptions on AGGREGATE caused core
794 * A null pointer was dereferenced, causing a core dump, when
795 PERCENTILES was specified on FREQUENCIES. This fixes the
796 problem, but PSPP still doesn't calculate percentiles.
798 * SORT always sorted in ascending order. Fixed.
800 * Some minor memory leaks in the expression parser were removed.
802 * Many assertions fixed for strict ANSI C compliance.
806 * SET ECHO ON now implemented, but turned off by default.
808 * PRINT specifier supported on END REPEAT.
812 * System libgmp2 library is used if installed instead of
813 unconditionally using the included libgmp2 subset.
815 * Extensive code cleanup, which continues.
817 * Added CORRELATIONS command parser, but not implemented.
819 Version 0.2.3 changes since 0.2.2:
823 * SPLIT FILE with a string variable caused a core dump. Fixed.
825 * Nested INCLUDEs didn't work. Fixed.
827 * The MATCH FILES procedure set the values of variables not present
828 to 0. It should have been SYSMIS. This is now fixed.
830 * The REMARK command was too aggressive about skipping lines. It
831 didn't like being the last command in a file.
833 * Comment parsing wasn't consistent with the rest of the code in its
834 idea of where one command ends and another starts. This meant
835 that sometimes commands would be mysteriously ignored. Thanks to
836 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
838 * The TABLE subcommand on MATCH FILES worked only erratically at
839 best. This fixes it. Thanks to Dr. Dirk Melcher
840 <BZN-mdksh@t-online.de> for reporting this bug.
842 * VARIABLE LABELS rejected a slash before the first variable
843 specification, contradicting the documentation. Thanks to Walter
844 M. Gray <graywm@northernc.on.ca> for reporting this bug.
846 * Because of an incorrect optimization in memory allocation,
847 CROSSTABS sometimes segfaulted when asked to output multiple
848 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
851 * CROSSTABS didn't display value labels for column and row
852 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
855 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
856 <BZN-mdksh@t-online.de> for reporting this bug.

859 best. This fixes it. Thanks to Dr. Dirk Melcher

875 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
876 <BZN-mdksh@t-online.de> for reporting this bug.
878 * MATCH FILES corrupted memory and dumped core on some syntax
881 * MATCH FILES should set numeric values not available to the
882 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
883 <BZN-mdksh@t-online.de> for reporting this bug.
885 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
886 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.

891 Hankin <hankin@rogue.consultco.com> for pointing this out.
893 * The SAVE procedure didn't save long string variables properly.
894 Fixed by this patch. Thanks to Hankin
895 <hankin@rogue.consultco.com> for this patch.

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