37 examine.q frequencies.q
38 html.c output.h piechart.c plot-chart.c plot-hist.c
40 Integrated the chart rendering into the output stream
41 (currently only works for html).
43 Removed gratuitous use of ifndef NO_CHARTS, and replaced with
44 dummy-chart.c for compiling without charts.
46 * mkfile.[ch] Created.
48 * som.[ch] tab.[ch]: Changed name of som_table to som_entity
49 Added type element so we can tell if it's a chart or a table.
51 * chart.h examine.q piechart.c plot-chart.c plot-hist.c: changed the
52 API of charts to be more like that of tables.
54 Thu Jan 13 21:00:02 WST 2005 John Darrington <john@darrington.wattle.id.au>
56 * casefile.c main.c: Moved the SIGINT handler from casefile.c to

74 (merge_once) Fix plenty of stupid mistakes.
76 Sat Jan 8 23:55:27 2005 Ben Pfaff <blp@gnu.org>
78 * casefile.c: (casefile_sleep) Need to flush_buffer() after
79 calling casefile_to_disk() or we will lose the last block in the
80 file if the casefile started out as disk-based.
81 (casefile_get_reader) Initialize reader->destructive to 0.
82 (cmd_debug_casefile) Add new test pattern.
83 (test_casefile) Define new test pattern to make sure
84 casefile_sleep() works properly.
86 Fri Jan 7 08:00:05 WST 2005 John Darrington <john@darrington.wattle.id.au>
88 * Makefile.am chart.[ch] histogram.[ch] piechart.c (Modified);
89 plot-hist.c plot-chart.c (Added) Reorganised these files in an
90 attempt to seperate the creation and processing of charts from their
93 * examine.q frequencies.q generated charts conditional upon the NO_CHARTS
96 Thu Jan 6 18:48:58 WST 2005 John Darrington <john@darrington.wattle.id.au>

102 Wed Jan 5 21:23:31 2005 Ben Pfaff <blp@gnu.org>
104 * sort.c: (merge) Fix assertion for proper Huffman merge pattern:
105 0 == 1 modulo 1. See Knuth 5.4.9 (vol. 3, 2nd ed.,
106 pp. 361). Thanks to John Darrington <john@cellform.com.au> for
109 Wed Jan 5 22:42:26 WST 2005 John Darrington <john@darrington.wattle.id.au>
111 * case.h Fixed bug # 11307
113 Wed Jan 5 08:30:48 WST 2005 John Darrington <john@darrington.wattle.id.au>
115 * val-labs.c Fixed bug which caused a crash if VALUE LABELS had
118 Mon Jan 3 17:44:37 2005 Ben Pfaff <blp@gnu.org>
120 * pfm-read.c: (read_variables) Remove direct manipulation of
121 v->aux, which is no longer needed. Fixes Bug #11483.
123 Sat Jan 1 19:01:16 WST 2005 John Darrington <john@darrington.wattle.id.au>
125 * data-list.c Fixed a bug in parsing delimiters.
127 * group.c vars-atr.c Fixed buglet in hash/compare functions for alpha
130 * percentiles.c Properly handled calculation of Tukey hinges where
131 the number of data is small.
133 * oneway.q Used the generic value_to_string function for independent
134 variable instead of trying to do it ourselves.
136 * box-whisker.c Fixed a buglet which caused a crash if the number of
140 Fri Dec 31 16:47:45 WST 2004 John Darrington <john@darrington.wattle.id.au>
142 * examine.q box-whisker.c chart.h Implemented boxplots in EXAMINE
144 * percentiles.c Fixed some bugs when calculating percentiles when
145 there's a small number of cases.
147 Wed Dec 29 08:18:08 WST 2004 John Darrington <john@darrington.wattle.id.au>
149 * percentiles.[ch] Added. Calculates percentiles and Tukey hinges

153 Fri Dec 24 15:09:11 WST 2004 John Darrington <john@darrington.wattle.id.au>
155 * t-test.q Fixed bug #11227 Made t-test work when the independent
158 Sat Dec 11 11:43:45 WST 2004 John Darrington <john@darrington.wattle.id.au>
160 * factor_stats.c Fixed calculation of trimmed mean under various
163 Sat Dec 4 17:14:45 WST 2004 John Darrington <john@darrington.wattle.id.au>

167 Added code to calculate sensible histogram ranges and limits.
169 Thu Dec 2 13:37:43 WST 2004 John Darrington <john@darrington.wattle.id.au>
171 * chart.h Updated to reflect many API changes.
173 * cartesian.c chart.c Moved the definitions of chart_write_{xy}scale from
174 cartesian.c and into chart.c
176 * factorstats.[ch] Added the histogram calculations
178 * casefile.c Removed an unused variable.
180 * frequencies.q examine.q histogram.c Reworked the API for
183 * piechart.c Revised the API for piecharts.
185 * var.h Moved the definitions of freq_tab and freq out of var.h
186 and into frequencies.q where they belong.
188 Tue Nov 30 21:10:20 2004 Ben Pfaff <blp@gnu.org>
190 * flip.c: (flip_file) Check for off_t separately from fseeko(),
193 Tue Nov 30 08:47:41 2004 Ben Pfaff <blp@gnu.org>
195 * flip.c: (flip_file) If fseeko() is not available, use long int
196 for off_t. Thanks to "Marshall DeBerry" <mdb@radix.net> for
197 reporting the problem.
199 Mon Nov 29 12:20:59 WST 2004 John Darrington <john@darrington.wattle.id.au>
201 * examine.q factor_stats.[ch] Changed stderr to se_mean to avoid
204 Sun Nov 21 10:32:41 WST 2004 John Darrington <john@darrington.wattle.id.au>
206 * var-labs.c (var_to_string) Now returns null if the variable is null
208 * value-labels.c (value_to_string) Made it return null if either the
209 value or the variable is null.
211 * hash.c (hsh_clear) Fixed a buglet.
213 * examine.q factor_stats.[ch] Largely rewrote, because I'd started
214 with the wrong model.
216 * casefile.[ch] Added a function to return the casereader.case_idx
219 * examine.q Implemented the extreme values results.
221 John Darrington <john@darrington.wattle.id.au>

224 output.[ch] getline.c
226 Plugged some memory leaks
228 Mon Nov 15 23:47:40 2004 Ben Pfaff <blp@gnu.org>
230 Adopt GSL random number generators, paving the way for providing
231 the complete suite of random number generators on expressions.
233 * Makefile.am: Remove random.c, random.h.
239 * algorithm.c: (algo_default_random) Use GSL functions.
241 * casefile.c: (test_casefile) Use GSL RNG functions.
243 * expr-evl.c: (expr_evaluate) Use GSL RNG functions for OP_NORMAL,
246 * sample.c: (cmd_sample) Use GSL RNG functions.
247 (sample_trns_proc) Ditto.
249 * set.q: (static var set_seed) Removed.
250 (static var seed_flag) Removed.
251 (static var rng) New variable.
252 (aux_stc_custom_seed) No seed value anymore, don't print anything.
253 (stc_custom_seed) Use new seed functions.
254 (seed_is_set) Removed.
255 (get_rng) New function that composes the entire external
257 (set_rng) New function.
258 (random_seed) New function.
260 Mon Nov 15 22:08:25 2004 Ben Pfaff <blp@gnu.org>
262 * expr-evl.c: (expr_evaluate) Fix XDATE.JDAY formula. Thanks to
263 John Darrington <john@darrington.wattle.id.au> for reporting this
266 Tue Nov 16 13:19:18 WST 2004 John Darrington <john@darrington.wattle.id.au>
268 * permissions.c command.def Added the PERMISSIONS command
270 Mon Nov 15 01:33:32 2004 Ben Pfaff <blp@gnu.org>
272 * q2c.c: (dump_header) Don't try to emit #includes at very top of
273 output file because that will precede #include <config.h>, which
275 (main) Add needed headers to /* (header) */ code.
277 Mon Nov 15 01:21:36 2004 Ben Pfaff <blp@gnu.org>
279 Instead of making system or portable file readers responsible for
280 dropping and reordering variables, make them read full cases and
281 let the caller take care of any changes.
283 * get.c: New "case map" structure to handle this. Use for GET,
284 IMPORT, MATCH FILES. Essentially rewrite the whole file.
286 * pfm-read.c: (pfm_read_case) Read into provided case. Signature
287 changed appropriately.
289 * sfm-read.c: (sfm_read_case) Ditto.
291 Mon Nov 15 00:47:45 2004 Ben Pfaff <blp@gnu.org>
293 Decided that case_serialize() and case_unserialize() were too
294 abstract. Also we need a couple more functions to avoid excessive
295 copying for data in/out fast paths.
297 * case.c: (case_serial_size) Removed.
298 (case_serialize) Rename case_to_values() and make its argument
299 explicitly an array of union values.
300 (case_unserialize) Rename case_from_values() and make its argument
301 explicitly an array of union values.
302 (case_data_all) New function.
303 (case_data_all_rw) New function.
305 * casefile.c: (struct casefile) Change buffer from array of
306 unsigned char to array of union value for better accuracy.
307 Redefine buffer_used and buffer_size in terms of values, not
308 bytes. Remove case_size because it is now redundant with
309 value_cnt. Fix up all references to these members.
311 Mon Nov 15 00:45:46 2004 Ben Pfaff <blp@gnu.org>
313 * barchart.c: (struct subcat) Make `label' member const to silence
314 GCC warning with -Wwrite-strings.
316 * cartesian.c: (struct dataset) Ditto.
318 * case.c: Don't re-define NDEBUG if already defined.
319 Add lots of comments.
321 * str.c: Fix includes.
323 * crosstabs.q: Fix includes.
325 * examine.q: Fix includes. Fix GCC warning about unused
328 * frequencies.q: (stat macro) Removed and replaced where used by
331 * list.q: Fix includes.
333 * oneway.q: Fix includes.
335 * piechart.c: Fix includes. Only define M_PI if not already
338 * sfm-read.c: (bswap) New function.
339 (bswap_int32) Write in terms of bswap.
342 * str.c: (ds_data) Add external definition here, needed because
343 str.h has only an `extern inline' version.
345 * value-labels.c: Fix includes.
347 Mon Nov 15 00:40:55 2004 Ben Pfaff <blp@gnu.org>
349 Instead of providing a system or portable file writer with a raw
350 case in the format needed for output, provide it with a regular
351 case. The writer takes care of any needed translation.
353 * aggregate.c: Adopt new scheme for AGGREGATE.
354 (struct agr_proc) sfm_agr_case member removed.
355 (write_case_to_sfm) Removed because the new interface is easier to
358 * get.c: Adopt new scheme for SAVE, XSAVE, EXPORT.
360 * pfm-write.c: Implement new scheme.
362 * sfm-write.c: Ditto.
364 Mon Nov 15 00:32:24 2004 Ben Pfaff <blp@gnu.org>
366 Instead of treating `struct file_handle' as a class to subclass
367 into data files, system files, and portable files, instead use it
368 as a helper that coordinates access. Now it is opaque, too.
370 This means that most references to a struct file_handle are now
371 changed into references to one of struct dfm_reader, struct
372 dfm_writer, struct sfm_reader, struct sfm_writer, struct
373 pfm_reader, or struct pfm_writer, according to what's being read
376 Most related changes are only worth summarizing briefly.
378 * dictionary.c: (dict_clear) Destroy aux data in deleted
380 (dict_clear_aux) New function.
381 (dict_create_var) Initialize aux, aux_dtor.
382 (dict_delete_var) Destroy aux data in deleted variable.
384 * file-handle.h: (struct fh_ext_class) Removed.
385 (struct file_handle) Removed.
386 (fh_init_files) Removed.
388 * file-handle.q: Changed references to a handle's `private' member
389 to direct references.
390 (struct private_file_handle) Renamed file_handle.
391 Add next, open_cnt, type, open_mode, aux members.
392 (struct file_handle_list) Removed.
393 (extern var inline_file) Removed.
394 (static var file_handles) Changed from file_handle_list * to
396 (create_file_handle) Initialize new members.
397 (fh_close_handle) Removed.
398 (mode_name) New function.
399 (fh_open) New function.
400 (fh_close) New function.
401 (fh_parse_file_handle) Renamed fh_parse().
403 * glob.c: (init_glob) Remove fh_init_files() call.
405 * aggregate.c: use sfm_writer.
406 (create_sysfile) Removed because the new interface is simpler.
408 * apply-dict.c: Use sfm_reader.
410 * data-list.c: Use dfm_reader.
412 * file-type.c: Use dfm_reader.
414 * get.c: Use sfm_reader, sfm_writer, pfm_reader, pfm_writer.
416 * inpt-pgm.c: Use dfm_reader.
418 * print.c: Use dfm_writer.
420 * sysfile-info: Use sfm_reader.
422 * dfm-read.c: Adopt new file handle infrastructure.
424 * dfm-write.c: Ditto.
428 * pfm-write.c: Ditto.
432 * sfm-write.c: Ditto.
434 Mon Nov 15 00:31:44 2004 Ben Pfaff <blp@gnu.org>
436 Break dictionary functions into separate header file.
438 * dictionary.h: New file.
440 * var.h: Moved dict_*() functions to dictionary.h.
442 Mon Nov 15 00:30:33 2004 Ben Pfaff <blp@gnu.org>
444 Get rid of procedure-specific union in struct variable, using
445 instead a void * pointer and a destructor function.
447 Most related changes are only worth brief summaries.
449 * crosstabs.q: Fix includes. Use new struct var_range in lieu of
450 old p.crs member in struct variable.
452 * frequencies.q: Fix includes. Use new struct var_freqs in lieu
453 of old p.frq member in struct variable.
455 * histogram.c: (draw_histogram) Takes new freq_tab arg because
456 it's no longer possible to grab this from var->p.frq.
458 * piechart.c: (draw_piechart) Ditto.
460 * group.c: (group_proc_get) New function.
462 * levene.c: Use group_proc_get() in lieu of old p.grp_data member
469 * main.c: (execute_command) Clear aux data in default_dict after
470 each command. (It's debatable whether this should be done.)
472 * matrix-data.c: Use new struct mxd_var in lieu of old p.mxd
473 member in struct variable.
475 * means.q: Get rid of integer mode, which is not included in
476 recent SPSS and was the only code that wanted per-variable private
479 * var.h: (struct crosstab_proc) Removed.
480 (struct frequencies_proc) Removed.
481 (struct list_proc) Removed.
482 (struct get_proc) Removed.
483 (struct means_proc) Removed.
484 (struct matrix_data_proc) Removed.
485 (struct match_files_proc) Removed.
486 (lots of enums) Removed.
487 (struct variable) Removed members `p', `get'. Add member
490 * vars-atr.c: (var_attach_aux) New function.
491 (var_detach_aux) New function.
492 (var_clear_aux) New function.
493 (var_dtor_free) New function.
494 (discard_variables) Use NULL instead of inline_file.
496 Fri Nov 12 10:07:11 WST 2004 John Darrington <john@darrington.wattle.id.au>
498 * value-labs.c Fixed the implmentation of value_to_string, so
499 that it properly handles alpha values.
501 * oneway.q Changed instances where labels were being probed manually,
502 to use the canonical {var,value}_to_string functions
504 Thu Nov 11 21:01:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
506 * examine.q cartesian.c chart.[ch] Added normal and detrended normal
507 plots. Changed the API of the cartesian plot to be a much lower level
510 Sun Nov 7 17:25:04 WST 2004 John Darrington <john@darrington.wattle.id.au>
512 * examine.q Added some of the parametric calculations
514 * factor_stats.[ch] Created
516 Sat Nov 6 21:24:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
518 * examine.q Changed the definition of factors to be a composite, and
519 dealt with the consequences.
521 Sat Nov 6 20:40:38 WST 2004 John Darrington <john@darrington.wattle.id.au>
523 * examine.q Fixed problem where examine wasn't dealing properly with
526 Sat Nov 6 14:49:47 WST 2004 John Darrington <john@darrington.wattle.id.au>
528 * oneway.q Fixed problem where oneway wasn't dealing properly with
531 Thu Nov 4 11:09:01 WST 2004 John Darrington <john@darrington.wattle.id.au>
533 * q2c.c examine.q Fixed a bug (feature?) whereby arrays in the
534 command which had settings didn't get the appropriate code
537 * val.h value-labels.[ch] var-labs.c Added v*to_string functions
538 to convert variables/values to strings.
540 * examine.q Added framework for the EXAMINE command.
542 Mon Nov 1 12:46:17 WST 2004 John Darrington <john@darrington.wattle.id.au>
544 * q2c.c frequencies.q set.q t-test.q Fixed the q2c parsing of DBL
545 subcommand types. Changed frequencies.q to use it rather then the
546 custom parser. Dealt with the consequences. Added a test for NTILES
547 subcommand of frequencies.
549 Sat Oct 30 09:16:29 WST 2004 John Darrington <john@darrington.wattle.id.au>
551 * oneway.q Fixed up the behaviour when given missing values
553 * levene.c oneway.q Fixed a buglet with the levene statistic and
554 incorporated the levene test into the oneway command.
556 * group.h t-test.q Moved the CMP_EQ and CMP_LE symbols out of
557 global scope, since they're only relevant to T-TEST
559 Fri Oct 29 17:39:03 WST 2004 John Darrington <john@darrington.wattle.id.au>
561 * group.c group.h group_proc.h levene.c oneway.q t-test.q
563 Made the t-test more consistent
564 with the way it handles groups. That is, it now uses a hash instead
565 of an array of 2. Also, made the levene.c file independent of the
566 implementation of the t-test. So now levene should be fine for both
569 * Added an oneway.q file for one way anova
571 Wed Jun 2 22:08:02 2004 Ben Pfaff <blp@gnu.org>
573 * descript.c: (cmd_descriptives) Remove harmless but bogus test in
576 Mon May 31 20:45:24 2004 Ben Pfaff <blp@gnu.org>
580 * data-list.c: (cmd_data_list) Free dls->delims on lossage.
581 (data_list_trns_free) Free dls->delims.
583 * t-test.q: (tts_custom_pairs) Free vars.
584 (ssbox_one_sample_init) Fix tab_vline() argument.
585 (ssbox_independent_samples_init) Ditto.
586 (trbox_paired_init) Ditto.
587 (trbox_one_sample_init) Ditto.
589 Mon May 31 17:19:27 2004 Ben Pfaff <blp@gnu.org>
591 Generalize casefiles to the extent that we can use them for
592 sorting and other kinds of data transformations. Change cases to
593 be copy-on-write to improve memory efficiency in common cases.
594 Every access to a member of a `struct ccase' was changed to be a
595 call to a case_*() function, especially case_data(), case_num(),
596 case_str(), or case_data_rw(). Many instances of a local variable
597 named "case_num" were changed to "case_idx" as a consequence.
598 Many `struct ccase *' were changed to actual `struct ccase'
599 because of copying semantics of cases. In several places there
600 was a choice between updating debug code to work with the new ADTs
601 or just deleting it because it was useless; I chose to delete it.
603 * Makefile.am: (pspp_SOURCES) Add case.c, case.h.
609 * aggregate.c: (struct agr_proc) Change type of `sort' to
610 sort_criteria *. Add `break_vars', `break_var_cnt' members.
611 Rename `vars' to `agr_vars', all references updated. Change
612 `agr_case' to type `struct ccase'.
613 (cmd_aggregate) Deal with new members. Use case_create(),
614 sort_active_file_in_place(), sort_active_file_to_casefile().
615 (agr_destroy) Deal with new members.
616 (aggregate_single_case) Ditto.
617 (dump_aggregate_info) Ditto.
618 (initialize_aggregate_info) Ditto.
619 (agr_to_active_file) Ditto.
620 (presorted_agr_to_sysfile) Ditto.
621 (sort_agr_to_sysfile) Removed.
623 * alloc.c: (out_of_memory) Make non-static.
625 * alloc.h: Prototype out_of_memory().
627 * casefile.c: Switched from a linked list in-memory representation
628 to a two-level array-style representation. The linked list was
629 appropriate when we could stick a header onto cases, but that's no
630 longer the case. Also, the two-level array will allow for random

633 the underlying casefile as they are read out.

950 (reader_open_file) Ditto.
952 Sun May 30 18:20:12 2004 Ben Pfaff <blp@gnu.org>
954 Update our string ADTs, struct string and struct len_string. Get
955 rid of pool support, which was largely unused. Rename lots of

991 Mon Apr 26 22:40:07 2004 Ben Pfaff <blp@gnu.org>
993 We're abusing the current ASCII driver by telling it to allocate a
994 9999-line, 9999-character page in the tests. This causes some
995 systems to curl up and die because it allocates 20 MB of
996 contiguous RAM. This change alleviates at least part of the
997 problem. It is mostly a stop-gap until the new output system is
1000 * ascii.c: (struct line) New structure.
1001 (struct ascii_driver_ext) Remove `page', `page_size', `line_len',
1002 `line_len_size', `n_output' members. Add `lines', `lines_cap'.

1021 Fri Apr 16 23:59:51 2004 Ben Pfaff <blp@gnu.org>
1023 Contrary to what I'd always understood, there is an efficient

1038 Sun Apr 11 14:22:12 2004 Ben Pfaff <blp@gnu.org>
1040 Rework moments routines for improved numerical stability based on
1041 Michael Kiefte's advice. Any bugs or remaining numerical problems
1042 are still mine though.
1044 There is now a struct moments1 for use with one-pass moments. It
1045 uses a provisional means algorithm as an attempt to improve
1046 accuracy of higher moments. The older struct moments now only
1047 handles two-pass moments.
1049 * aggregate.c: Use moments1 instead moments.
1051 * descript.c: Revert previous change, which is no longer needed
1052 due to the moments revision.
1054 * moments.c: (calc_moments) New function for calculating variance,
1056 (moments_pass_one) Only accumulate weights bigger than zero.
1057 (moments_calculate) Allow calculating the mean on pass one, others
1058 require pass two. Implement in terms of calc_moments().
1059 (struct moments1) New structure.
1060 (init_moments1) New function.
1061 (moments1_clear) Ditto.
1062 (moments1_create) Ditto.

1077 * descript.c (calc_descriptives): Fix assert failure when only
1078 MOMENT_MEAN is needed.
1080 2004-04-09 Michael Kiefte <mkiefte@dal.ca>
1084 fixed problem with parsing in match_statistic() causing
1085 "DESCRIPTIVE STAT=MEAN." to barf.
1087 "MEAN" is now default if "SORT" given without specification.
1089 Fixed infinite loop with "DESCRIPT GIBBERISH=ALL." Parsing is
1090 generally less forgiving of syntax errors: better to have it do
1091 nothing and type it in again then to not know what it actually did
1094 z-score transformation now checks score for user-missing values
1095 and checks std_dev for SYSMIS.
1097 2004-04-06 Michael Kiefte <mkiefte@dal.ca>
1099 * aggregate.c, crosstabs.q, descript.c, dictionary.c, frequencies.q, levene.c, t-test.q, var.h:
1100 Changed dict_get_case_weight() to accept an additional int * flag
1101 to complain about system-missing, user-missing, zero, or negative
1102 weights and updated existing functions to pass int * to
1103 dict_get_case_weight().

1130 * Makefile.am: Added the --ansi flag and dealt with the
1131 consequences. Added some entries to PSPP_sources so that
1132 make distcheck would pass
1134 * cmdline.c: Added the --syntax and --algorithm options
1136 * q2c.c: Added an implicit /ALGORITHM subcommand to everything.
1138 Fri Apr 2 11:25:22 WAST 2004 John Darrington <john@darrington.wattle.id.au>
1140 * t-test.q, levene.c, levene.h Converted t-test (incl levene) to
1141 use the new multipass_split_... mechanism.
1143 Wed Mar 31 22:36:22 2004 Ben Pfaff <blp@gnu.org>
1145 * frequencies.q: (calc_stats) Use moments data structure and
1146 calc_seskew(), calc_sekurt() functions.
1148 * set.q main.c settings.h Added support for --syntax and --algorithm
1151 Tue Mar 30 22:04:19 2004 Ben Pfaff <blp@gnu.org>
1153 * vfm.c: Had to get last call to multipass_split_output() inside
1154 open_active_file()/close_active_file() pairing, so introduce new
1156 (internal_procedure) Move procedure() code here, except for calls
1157 to open_active_file() and close_active_file().

1527 Sat Mar 20 15:18:16 2004 Ben Pfaff <blp@gnu.org>
1529 Changed DFM from open-at-first-access to explicit-open. Before,
1530 calling dfm_get_record() or dfm_put_record() would automatically
1531 open the file. Now, you have to call dfm_open_for_reading() or
1532 dfm_open_for_writing() explicitly. This makes it possible to

1649 Fixed cmd_parse() so that it always skips past a full command
1650 name. A few special commands for which this would be bad get
1651 special treatment. This lets us drop code for skipping past the
1652 end of a command name in most cmd_*() functions. It's not worth
1653 listing all the commands affected.
1655 * command.c: (struct command) Remove `cmd' member, replace by
1656 `name' member, all references updated. Remove `word', `next',
1657 `skip_entire_name' members.

1713 * set.q: Implemented the SHOW command, and synced it to the existing
1716 Added a handler for SIGWINCH so that viewlength and viewwidth follow
1717 changes as the window size is changed.
1719 Added fallback to set viewlength and viewwidth from LINES and COLUMS
1720 environment variables if other methods are not available.
1722 glob.c: Removed a lot of global variables from glob.c and encapsulated
1725 random.c: Tidied up the way the random seed is set.
1727 str.c: Added a ds_vprintf function.
1729 error.c: Extended dump_message so that messages are always broken at
1732 Thu Mar 18 11:07:14 2004 Ben Pfaff <blp@gnu.org>

2869 through these arguments. In some cases this meant that the extra
2870 args had to be threaded through a couple of extra levels. This
2871 wasn't difficult or interesting so the details won't be given.

2874 `write_case', `wc_data' as kluge.

2884 transformations, so that they know where to send their cases.
2885 It's a big kluge. Also kluge in END CASE.

2924 pref.h. Change use of __WIN32__, __MSDOS, __DJGPP__,
2925 __CYGWIN32__, __unix__, and unix not to assume that they're
2926 defined to a nonzero value. Change use of __attribute__ to use
2927 NO_RETURN or PRINTF_FORMAT instead.
2929 * alloc.h: Move definitions for local_alloc(), local_free() here
2930 from ../pref.h.orig and simplify.
2932 * expr-evl.c: Instead of working differently based on PAGED_STACK,

3014 Start working on a new output driver system, one that doesn't suck
3015 so much, by adding a "device-independent" output driver. The idea
3016 is to write out only a single output stream, then use separate
3017 processes to translate them into whatever formats we want. This
3018 is similar to how "groff" works with its various output drivers
3019 (grops, grotty, grodvi, ...).

4054 functions than the ones we had, and cleaned up the names to boot:
4056 * hash.c: (hashpjw_d) Removed.

4074 Made deletion possible, though slow:
4076 * hash.c: (locate_matching_entry) New function.
4077 (hsh_find) Use locate_matching_entry().

4762 <BZN-mdksh@t-online.de> for reporting this bug.
4764 * aggregate.c: (parse_aggregate_functions) When setting the
4765 FSTRING bit, also allocate memory for the `string' member of
4767 (free_aggregate_functions) Free iter->string. Don't use the
4768 non-function bits when indexing the array of functions.
4769 [DEBUGGING] (debug_print) Don't use the non-function bits when
4770 indexing the array of functions.
4772 Sun May 30 00:00:54 1999 Ben Pfaff <blp@gnu.org>
4774 Under certain circumstances, the final case would be omitted from
4775 the results of an AGGREGATE operation. Fixed. Thanks to Dr. Dirk
4776 Melcher <BZN-mdksh@t-online.de> for reporting this bug.
4778 * aggregate.c (agr_00x_end_func): Increment number of cases in
4779 sink before writing case. For streams that keep track of how many
4780 cases there are based on this value, this means that the last case
4781 will be read in on the next stream read.
4783 Sat May 29 22:03:31 1999 Ben Pfaff <blp@gnu.org>
4785 Undefined behavior was invoked by referencing a freed pointer.
4787 * vfm.c (memory_stream_write): Free pointer *after* checking for

4802 * sort.c: (allocate_cases) Initialize i.
4804 Sat May 29 21:40:54 1999 Ben Pfaff <blp@gnu.org>
4806 Syntax errors in function descriptions on AGGREGATE caused core
4809 * aggregate.c (cmd_aggregate): Don't free agr_dict after calling
4810 free_aggregate_functions(), since that function already frees
4813 Sat May 29 21:06:10 1999 Ben Pfaff <blp@gnu.org>
4815 A null pointer was dereferenced, causing a core dump, when
4816 PERCENTILES was specified on FREQUENCIES. This fixes the problem,
4817 but PSPP still doesn't calculate percentiles. Thanks to Regnor
4818 Jernsletten <rjernsle@eunet.no> for reporting this problem.
4820 * arena.c: (arena_malloc) If the arena hasn't been initialized

4838 Tue Mar 9 13:18:54 1999 Ben Pfaff <blp@gnu.org>
4840 SPLIT FILE with a string variable caused a core dump. Fixed.
4842 * vfm.c: If the variable is a string then make a temporary value
4843 struct pointing to it. The underlying problem is a lot bigger
4844 than this (see TODO) but this is a stopgap for the simple case at
4847 Tue Mar 9 13:15:53 1999 Ben Pfaff <blp@gnu.org>
4849 Nested INCLUDEs didn't work. Fixed.
4851 * getline.c: (getl_include) Set first_line to NULL in allocated
4854 Tue Mar 9 13:13:46 1999 Ben Pfaff <blp@gnu.org>
4856 The MATCH FILES procedure set the values of variables not present
4857 to 0. It should have been SYSMIS. This is now fixed.
4859 * get.c: (mtf_delete_file_in_place) Replace 0.0 by SYSMIS.
4861 Tue Mar 9 12:52:23 1999 Ben Pfaff <blp@gnu.org>
4863 The REMARK command was too aggressive about skipping lines. It
4864 didn't like being the last command in a file.
4866 * command.c: (cmd_remark) Call get_entire_line() instead of
4869 Tue Mar 9 12:48:05 1999 Ben Pfaff <blp@gnu.org>
4871 Comment parsing wasn't consistent with the rest of the code in its
4872 idea of where one command ends and another starts. This meant
4873 that sometimes commands would be mysteriously ignored. Thanks to
4874 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
4876 * command.c: (parse_cmd) Hand off comment parsing to new function
4877 skip_comment() in lexer.c.
4878 * lexer.c: (skip_comment) New function.
4880 Wed Jan 20 20:22:07 1999 Ben Pfaff <blp@gnu.org>
4882 The TABLE subcommand on MATCH FILES worked only erratically at
4883 best. This fixes it. Thanks to Dr. Dirk Melcher
4884 <BZN-mdksh@t-online.de> for reporting this bug.
4886 * get.c: (mtf_compare_BY_values) When comparing string values, a
4887 difference of 1 is still a difference :-)
4888 (mtf_processing) Inverted TABLE reading logic fixed. Also don't
4889 advance TABLE files automatically when matched. Comment fixes.
4891 Tue Jan 19 22:32:31 1999 Ben Pfaff <blp@gnu.org>
4893 VARIABLE LABELS rejected a slash before the first variable

4897 * var-labs.c: (cmd_variable_labels) Ignore a leading slash in
4898 command specification.
4900 Tue Jan 19 22:29:54 1999 Ben Pfaff <blp@gnu.org>
4902 Because of an incorrect optimization in memory allocation,
4903 CROSSTABS sometimes segfaulted when asked to output multiple
4904 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
4907 * crosstabs.q: (postcalc) New variables maxcols, maxcells, which
4908 are passed to output_pivot_table() for its use.
4909 (output_pivot_table) Instead of assuming the number of columns is
4910 constant, keep track with maxcols. In general mode, use maxcells
4911 to determine whether more matrix cells need to be allocated.
4913 Tue Jan 19 22:27:46 1999 Ben Pfaff <blp@gnu.org>
4915 CROSSTABS didn't display value labels for column and row
4916 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
4919 * crosstabs.q: (table_value_missing) If the specified value has a
4920 value label for this variable, then show it instead of the raw
4922 (display_dimensions) Delegate display of value_labels to
4923 table_value_missing.
4925 Mon Jan 18 20:04:06 1999 Ben Pfaff <blp@gnu.org>
4927 WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
4928 <BZN-mdksh@t-online.de> for reporting this bug.
4930 * print.c: (print_trns_proc) Write (CR/)LF if PRINT is used _or_
4931 if the file isn't declared as binary.
4933 Mon Jan 18 19:56:45 1999 Ben Pfaff <blp@gnu.org>
4935 MATCH FILES corrupted memory and dumped core on some syntax
4938 * get.c: (cmd_match_files) Set file->handle to NULL before
4940 (mtf_free_file) Don't free a null dictionary.
4942 Mon Jan 18 19:27:57 1999 Ben Pfaff <blp@gnu.org>
4944 MATCH FILES should set numeric values not available to the
4945 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
4946 <BZN-mdksh@t-online.de> for reporting this bug.
4948 * get.c: (mtf_processing) Set unused records to system-missing,
4951 Mon Jan 18 15:06:46 1999 Ben Pfaff <blp@gnu.org>

4954 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
4956 * temporary.c: (save_dictionary) Initialize var_by_name AVL tree
4957 in newly created dictionary, and add each copied variable to the

4964 * get.c: (trim_dictionary) Free variable list for KEEP after
4967 Mon Jan 18 12:57:36 1999 Ben Pfaff <blp@gnu.org>
4969 Some systems didn't like the way open_file was coded. Thanks to
4970 Hankin <hankin@rogue.consultco.com> for pointing this out.
4972 * filename.c: (open_file) Don't try to store stdin, stdout,
4973 stderr as part of an array, because that doesn't always work.
4975 Mon Jan 18 12:53:27 1999 Ben Pfaff <blp@gnu.org>
4977 The SAVE procedure didn't save long string variables properly.
4978 Fixed by this patch. Thanks to Hankin
4979 <hankin@rogue.consultco.com> for this patch.
4981 * sfm-write.c: (write_variable) Fix off-by-one error in writing
4982 out variable pad records.
4984 Tue Jan 5 14:29:27 1999 Ben Pfaff <blp@gnu.org>
4986 Previously, if PRINT SPACE were given a negative argument, it
4987 would report an error, then spin in an (almost) infinite loop.
4988 This fixes that behavior.
4990 * print.c: (print_space_trns_proc) After reporting a negative
4991 argument, set number of lines to print to 1.
4993 Tue Jan 5 13:59:55 1999 Ben Pfaff <blp@gnu.org>
4995 SPSS 8.0 outputs some new record types in its system files, and it
4996 allows longer value labels. Accept these system files.
4998 * sfm-read.c: (sfm_read_dictionary) Ignore record type 7 subtype
4999 11 emitted by SPSS 8.0.
5001 Tue Jan 5 13:55:50 1999 Ben Pfaff <blp@gnu.org>
5003 The LIST procedure was too conservative in allocating space for
5004 buffers, which caused a bug that only showed up with very long
5005 output variables. Thanks to Hankin <hankin@dunno.com> for this
5008 * list.q: (determine_layout) Allocate 1022 bytes instead of 256.
5010 Tue Jan 5 13:34:34 1999 Ben Pfaff <blp@gnu.org>
5012 Typo meant string format specifiers weren't checked properly. I
5013 think that Hankin <hankin@dunno.com> sent me this report, but I'm
5014 willing to be corrected on this point.
5016 * format.c: (check_string_specifier) Fix obvious typo.
5018 Tue Jan 5 12:50:42 1999 Ben Pfaff <blp@gnu.org>

5030 The changes in 0.2.1 to fix DATA LIST FREE parsing broke some
5031 other behavior, *sigh*. This patch hopefully fixes that. This
5032 time I've actually tested it.
5034 Thanks to Hankin <hankin@dunno.com> for reporting this bug.
5036 * data-list.c: (read_from_data_list_free,
5037 read_from_data_list_list) Call parse_string_as_format() directly

5043 interpreted in interactive mode. Make -i emulate this behavior to
5044 allow such scripts to be executed with PSPP.
5046 Thanks to Hankin <hankin@dunno.com> for reporting this behavior.
5048 * cmdline.c: (pre_syntax_message[]) Update -i description.
5050 * lexer.c: (preprocess_line) When getl_interactive is 2 (i.e.,
5051 when -i is given on the command line) don't treat unindented lines
5052 as starting a new command.
5054 Tue Jan 5 12:30:10 1999 Ben Pfaff <blp@gnu.org>
5056 In conjunction with egcs 1.1.1, Checker emits some bogus warnings,

5058 fixed upstream these can be removed, but for now they're not a big
5061 * ascii.c: (ascii_postopen_driver) Checker chokes on local
5062 initialized arrays. Avoid this.
5064 * sfm-write.c: (sfm_write_dictionary) Don't use a local
5067 Tue Jan 5 12:07:24 1999 Ben Pfaff <blp@gnu.org>
5069 egcs 1.1.1 has some new warnings relative to gcc 2.8.1, which the
5070 following changes avoid. Currently I compile sources with egcs
5071 1.1.1 and gcc 2.7.2.3 before sending them out.
5073 * apply-dict.c: (apply_dict) Use new avl_traverser_init() macro.

5106 * data-in.c: Examined each of the parsing functions to make sure
5107 that they wouldn't dump core if they were passed a string of the

5111 (parse_string_as_format) Reject input that's too short or too

5117 behavior. This is fixed in these changes. Thanks to Mark H. Wood
5118 <mwood@IUPUI.Edu>. In addition, this fixes a few more details of
5119 free-format parsing that differed from SPSS.

8413 * error.h: Removed CE, CW aliases for SE, SW.
8415 * q2c.c: Removed explicit streq() definition since it's duplicated
8418 * approx.h, error.h, font.h, hash.h, misc.h, output.h, somP.h,
8419 stats.h, str.h, tokens.h: Made the declarations of macros taking

8423 Sun Jun 1 12:02:06 1997 Ben Pfaff <blp@gnu.org>
8425 * cmdline.c: Comment fixes.
8426 (pick_compat) Changed return type to int. Now, instead of setting
8427 glob var `compat' to the emulation, returns the emulation. All
8429 (parse_command_line) Added terminating null to end of
8430 `long_options' array definition.
8431 (pre_syntax_message) Fixes.
8432 (usage) Shows the default emulation in the syntax message by
8433 calling pick_compat().
8435 * getline.c: (getl_add_include_dir) Separates paths with
8436 PATH_DELIMITER, not DIR_SEPARATOR.

8453 * ascii.c, postscript.c, sfm-read.c, sfm-write.c, sort.c: Include
8454 <errno.h>. GNU libc 2 enforces this!
8456 * command.c: (parse_cmd) Fixed problem with `else' clause being
8457 paired with wrong `if'. Comment fix.
8459 Fri May 9 16:53:52 1997 Ben Pfaff <blp@gnu.org>
8461 * getline.c: [!HAVE_LIBREADLINE] (read_console) Changed
8462 blp_getline() to getline().
8464 * output.c: (outp_eval_dimension) Changed the fix from last time;
8465 there was no variable `a'.
8467 * q2c.c: (get_line) Fixed boundary condition overrun bug.
8469 Mon May 5 21:58:22 1997 Ben Pfaff <blp@gnu.org>

8484 * output.h: (struct outp_class_struct) Removed
8485 text_get_font_position method. All references deleted.
8487 * postscript.c: Big change here. Fontmaps were completely
8488 eliminated because of a change in philosophy. Comment fixes.
8489 (struct ps_fontmap, ps2dit_map, font_family, dit2family_map)
8491 (struct ps_driver_ext) `position', `fontmap', `prop_name',
8492 `fixed_name' members removed. New members `prop_family',
8493 `fixed_family'. `family' member changed to type char *.
8494 (static var ps_fontmaps) Removed.
8496 (ps_init_driver) Removed obsolete references, updated.
8497 Initializes `translate_x', `translate_y', `scale'. Doesn't read
8498 fontmap, of course. Refers to font names through internal_name
8499 rather than subversive means. Frees proper items.
8500 (static var option_tab[]) Removed `fontmap-file' option; renamed
8501 `fixed-font', `prop-font'.
8502 (ps_option) Corresponds to option_tab[].
8503 (read_fontmap, release_fontmap, ps_to_dit, compare_ps2dit,
8504 hash_ps2dit, compare_dit2family, hash_dit2family, compare_family,
8505 hash_family) Removed.
8506 (postopen) Generates font names from family names. Gets
8507 PostScript font name properly. New prologue file comment `!!!'
8509 (ps_open_page) Adds translate_x, translate_y to BP prologue
8510 function; gives SF argument floating-point format.
8511 (ps_text_set_font_by_name) Doesn't try to map PostScript->Groff
8512 font name. Doesn't change font family.
8513 (ps_text_set_font_by_position) Generates Groff font name from font
8514 family name instead of through table lookup.
8515 (ps_text_set_font_by_family) Renamed `ps_text_set_font_family',
8516 all references changed. Reduced to simple string assignment.
8517 (ps_get_font_name) Removed.
8518 (ps_get_font_family) Reduced to string return.
8519 (text) Doesn't save `position' since it no longer exists. Ugly
8520 kluge to save font family--fix soon?
8521 (load_font) Removed PostScript name argument.
8523 Thu May 1 14:58:59 1997 Ben Pfaff <blp@gnu.org>
8525 * postscript.c: Comment fix.
8526 (ps_open_page) Puts scale factor in PostScript output.

8536 * command.c: Comment fix.
8537 (static var cmd_table[]) Re-enabled EVALUATE command.
8538 (parse_cmd) Lotsa comment fixes. Fixed infinite loop in parsing
8539 of comments in script files. Now more liberal on criteria for
8540 performing a state transition--if *anything* happened correctly,
8541 not just if *everything* happened correctly.
8543 * data-out.c: (convert_F) Comment fix. Why in the fsck does
8544 Checker segfault on formatting large numbers and why in the fsck
8545 hadn't I noticed this before?
8547 * expr.h, exprP.h: No longer turn off GLOBAL_DEBUGGING.
8549 * list.q: (cmd_list) Commented out the actual output routine
8550 because of various problems. Probably will abandon the idea of
8551 using the general `crushed tables' for the LIST procedure.
8553 * temporary.c: (restore_dictionary) Sets var_by_name to NULL after
8554 clearing it. Allocates a new var_by_name dictionary before trying
8555 to add members to it.
8557 * vars-atr.c: [DEBUGGING] (dump_one_var_node) Removed argument
8558 `sib'. Changed type of `node' argument.
8559 [DEBUGGING] (dump_var_tree) Replaced avlwalk() with
8561 (clear_variable) Only dumps the var tree if var_by_name non-NULL.
8562 [DEBUGGING] Only deletes the variable from var_by_name if that var
8565 Fri Apr 18 16:48:41 1997 Ben Pfaff <blp@gnu.org>
8567 * Makefile.am: Added include files to SOURCES. Added
8568 frequencies.q to EXTRA_DIST. Removed include/ from INCLUDES. Now
8569 includes rules for q2c. Added `boast' target.
8571 Fri Apr 18 15:42:22 1997 Ben Pfaff <blp@gnu.org>
8573 * Makefile.am: Maintainer-clean Makefile.in.
8575 * Makefile.am: Fixed redundant EXTRA_DIST line.
8577 * ascii.c: Comment fixes.
8578 (ascii_line_vert) Fixed overly aggressive range check.
8580 * display.c: Removed dead code.
8582 * list.q: Turn debugging on.
8583 (flush_table) New debug code.
8585 * sfm-read.c: (read_value_labels) malloc's the structure before
8586 trying to assign to its members.
8588 * sfm-write.c: Comment fix.
8590 * som-high.c: (som_submit_table) Sets som.t and som.d on each call
8592 (output_table) No arguments anymore--gets them through `som'
8593 global. New debug code. In crushed tables, now sets `htv' as
8594 well as `hv' to avoid bad confusion later.
8595 (dump_crush_page) New debug code.
8597 * som-low.c: (som_dump_crush_page) New debug code.
8599 Thu Mar 27 01:11:29 1997 Ben Pfaff <blp@gnu.org>
8601 All source files: Broke long lines into multiple lines.

8604 HOST_SYSTEM constant.
8606 * cmdline.c: (var syntax_message[]) Broke into
8607 pre_syntax_message[] and post_syntax_message[].
8608 (usage) Outputs both parts, separated by driver list.
8610 * error.h: Fixed broken formatting.
8612 * expr-opt.c: (str_search, str_rsearch) New functions.
8614 * misc.c: (blp_getdelim) Removed. All references changed to
8616 (str_search, str_rsearch) Removed.
8617 (memrmem) New function.
8619 * misc.h: (blp_getline) Removed. All reference changed to
8624 * filename.c: Includes "stat.h", not <sys/stat.h>.
8625 (blp_getenv) Uses host_system var instead of HOST_SYSTEM constant.
8627 * output.c: (outp_list_classes) Changed output formatting.

8630 HOST_SYSTEM constant.
8631 (write_rec_7_34) Extracts version numbers from the version string.
8634 * sort.c: Includes "stat.h", not <sys/stat.h>.
8636 * str.c: (strcasecmp) Removed.
8638 * title.c: (cmd_document) Uses host_system var instead of
8639 HOST_SYSTEM constant.
8641 * version.c: Generated on-the-fly by the Makefile instead of being
8644 * str.h: Comment fixes. Doesn't substitute for missing memmove or
8646 [!HAVE_STRNCASECMP] Declares strncasecmp().
8648 * version.h: Removed stray character. Comment fixes.
8649 (vars host_system, build_system) New vars.
8651 Mon Mar 24 21:47:31 1997 Ben Pfaff <blp@gnu.org>
8653 * Most source files: Changed formatting of copyright notice; fixed
8654 FSF address; reformatted to better conform to GNU standards;
8655 comment fixes. Added markups to prevent GNU indent from messing
8656 up my beautiful formatting :-).
8658 * q2c.c: (get_line) Ignores lines that begin with `/* *INDENT' so
8659 that GNU indent markups can be passed through without problems.
8661 Wed Feb 19 21:30:31 1997 Ben Pfaff <blp@gnu.org>
8663 * get.c: Turned off debugging.
8665 * glob.c: (init_glob) Turned on save-file compression by default.
8667 * sfm-write.c: (sfm_write_case) Fixed bug which resulted in less

8679 (static vars min_n, max_degree) Removed, all references removed.
8680 (internal_cmd_frequencies) Doesn't handle extensions. Doesn't
8681 calculate `min_n', `max_degree'.
8682 (postcalc) Passes new arg to dump_statistics().
8683 (dump_full) Honor NOLABEL option. Buggy? Adds variable name
8685 (dump_condensed) Adds variable name title.
8686 (sum_freqs) Removed.
8687 (calc_stats) Updated calculation algorithm.
8688 (dump_statistics) Removed warning for too-few observations.

8706 to free_expression(), which itself checks.
8708 * descript.q: Removed Fiasco extensions. Removed optimizations
8709 for non-weighted active files. Implemented some options.
8710 Finished polishing output format. Comment fixes. Merged

8715 (struct dsc_info_struct) Removed `min_n' member, all references
8717 (internal_cmd_descriptives) Removed calculation of min_n,

8720 (precalc) Eliminated redundancy. Updated for changes to
8721 descriptives_proc structure.
8722 (calc) Moved here from `descript.g'. Rewritten to calculate
8723 statistics via `moments about the mean' rather than by summing,
8724 summing squares, summing cubes, and so on.
8725 (postcalc) Rewritten for new-style statistical calculation.
8726 (display) Removed support for displaying variables across rows.
8727 No longer crushes the descriptives table. Removed ancient code.
8728 Added display of N, by variable and listwise.
8730 * descript.g: Removed; merged into `descript.q'.
8732 * expr-evl.c: (evaluate_expression) Now returns a double. For
8733 numeric results, it returns the result as well as storing it in
8734 the passed `value' structure if non-NULL. For string results it
8735 just returns 0.0 and it must be passed non-NULL. Many references
8736 to this function were optimized by use of this change, especially
8737 but not exclusively in `compute.c'.
8739 * frequencies.g: Comment fix.
8741 * glob.c: (glob var process_if_expr) New global var.
8743 * postscript.c: (static var option_tab[]) Corrected entry for

8753 (sfm_write_case) Increments `n_cases'.
8754 (sfm_close) Attempts to seek the system file back to the header
8755 and write the number of cases in its proper slot.
8757 * som-frnt.c: (som_insert_table) Masks off expansion options since
8758 only SOPT_X_NORM seems to work sensibly.
8760 * som-low.c: (get_cell_size) Fixed bug when a table cell was sized
8761 with a `fixed' value of 2.
8763 * sort.c: (cmd_sort_cases) Cancels PROCESS IF.
8765 * sysfile-info.c: (cmd_sysfile_info) Doesn't display more than 10

8779 * glob.c: (glob var err) Removed.
8781 * sysfile-info.c: (cmd_sysfile_info) When adjusting table size,
8782 doesn't have to take into account number of value labels since
8783 they're in a subtable anyway. Also, doesn't display more than 10
8784 value labels since we can't yet break pages in subtables.
8786 Tue Feb 4 15:15:50 1997 Ben Pfaff <blp@gnu.org>
8788 * som-frnt.c: (som_change_table_size) Simple change for elegance
8789 that shouldn't change behavior.
8790 (som_set_value) Comment fix.
8792 * som-high.c: (som_submit_table) Message fix.
8794 Wed Jan 22 21:54:00 1997 Ben Pfaff <blp@gnu.org>

8817 bizarre Checker problem, I guess.
8818 (read_variables) Proper cleanup on lossage.
8820 * sfm.h: (struct sfm_read_info) New struct for use by
8821 sfm_read_dictionary().
8823 * som-frnt.c: (som_create_table) New argument CREATE_FLAGS,
8824 currently used just for tables that can be dynamically resized and
8825 thus have to be allocated with arena_malloc() instead of
8826 arena_alloc(). All references changed.
8827 (som_change_table_size) New function.
8828 (som_insert_table) Bugfix: now inserts `cell', not `c'!
8830 * som-high.c: [GLOBAL_DEBUGGING] (check_table) Moved to som-low.c.
8831 (som_submit_table) [GLOBAL_DEBUGGING] Doesn't call check_table()

8872 nitems. Changed strcpy to memcpy (no null terminator).
8873 (convert_date) Fixed FMT_JDATE: added 1900 to year.

8911 non-NULL. Doesn't try to xstrdup() dictionary documents.
8912 Adapted so as to not irritate Checker.

8915 * title.c: (cmd_file_label) Doesn't skip FILE, LABEL tokens.
8916 (cmd_document) Doesn't skip DOCUMENT token. Adds some header
8917 lines to the document, indents the document. Also, it works now.

10863 * Many more changes to som.c especially, but these will not be
10864 documented as I have resolved to remove them. This patchlevel is
10865 being released solely so that I can fall back to it if I decide

10868 Sat Jul 13 09:58:44 1996 Ben Pfaff <blp@gnu.org>
10870 * som.c: (global var som) New member `cum_y'.

10935 frequencies.q, list.q, vars-prs.c, vfm.c: Removed reference to
10936 HAVE_MALLOC_H because Borland C++ alloca() is broken, so why
10937 include the corresponding header?

10947 som_submission_form. Function prototypes revised.
10949 Outputting huge tables (1000s of rows) a few rows at a time

10971 * Thanks to an unreliable IDE hard drive, I have spent the last
10972 day reconstructing my Debian GNU/Linux installation and redoing
10973 the previous day's changes--somehow I managed to save every file
10974 except for output.c and output.h. So the following changes could
10975 really be considered independent of the output.c, output.h changes
10978 * output.h, output.c: Moved the outp_configure_vec global var,
10979 outp_names struct, and enum set OUTP_S_* from output.h to output.c.

10982 Thu Jul 4 20:20:24 1996 Ben Pfaff <blp@gnu.org>
10984 * The entire philosophy behind configuration of the output drivers
10985 changed. Now there is a termcap-type configuration where drivers
10986 to be read are determined beforehand, rather than parsing the
10987 entire output init file and storing it in memory & deciding what
10988 to actually use later. Faster & more memory-efficient at the same
10991 * output.c: Comment fix. Removed outp_init_drivers global var.
10992 Removed all references to synonyms. New structure outp_defn. New
10993 global vars outp_macros, outp_configure_vec.

11003 (outp_list_classes) Bug fix, cleaned up.
11004 (outp_list_drivers) Not implemented anymore.

11016 * main.c: (main) Calls outp_read_devices() after parsing the
11019 * cmdline.c: (parse_command_line) New option -v --verbose;
11020 --version changed to -V. --device option changed syntax to just
11021 take a single device name. Accepts key=value declaration of
11022 output init file macros. Syntax message updated.
11024 * filename.c: (expand_line) New function.
11025 (interp_environ_vars) Renamed interp_vars; no longer uses
11027 (blp_getenv) Allows $ARCH and $VER pseudo-environment-vars to be
11028 overridden by real environment vars.
11029 (search_path) Uses verbose_msg() instead of #ifdef'd printf().
11030 * filename.h: interp_environ_vars() renamed interp_vars().
11032 * error.c, error.h: Added extern variable `verbosity', message
11035 * error.c: (vmsg) Support message class MM.

11040 (dump_z_table) Bug fix in column headers.
11042 * ascii.c: (ascii_init_driver) Changed minimum number of lines per
11043 page from 29 to 15. Don't set a default for ops[OPS_INIT,
11044 OPS_DONE]. Writes the uninit string when the driver is closed.
11045 (ascii_open_page) Write the init string before the first page.
11046 (output_shorts) Form of main loop changed from `while' to `for'.
11047 Bug fix with overstrikes: the character is printed *after* the
11048 backspace. Eliminated a lot of `& 0xff' modifiers.
11049 (advance_to_left_margin) New function.
11050 (return_carriage, output_lines) Handle left margin.
11052 Thu Jul 4 00:35:59 1996 Ben Pfaff <blp@gnu.org>
