133: - major bug is fixed in READ intrinsic (socket). This bug was introduced
134: by a new feature in glibc.
135: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
136: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
137: "ALL" IMPLICIT when it runs in interactive mode;
138: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
139: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
140: to use SAVE to manipulate global variables;
141: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
142: subroutines;
143: - fix major memory access violation in evaluation subroutine. Only occurs
144: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
145: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
146: when X was a vector or a table.
147: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

176: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
177: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
178: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
179: corruption. As internal memory management have been improved, a best fit
180: allocator like ptmalloc3 is not required anymore;
181: - gnuplot is upgraded to 4.4.1;
182: - deadlock is fixed in signal handlers: same mutex was used in standard
183: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
184: and signal handlers. A new signal handler specific mutex is added;
185: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
186: that has to be evaluated by ->NUM;
187: - rplfile build process is modify to be sure that rplfile is not modified
188: after rpl build stage (to be sure that rplfile checksum is not modified after
189: rpl compilation);

193: ABORT now works on eComStation;
194: - sqlite is upgraded to 3.7.2;
195: - bug is fixed in software interrupts. When both process have different PID,
196: parent process was not interrupted if it is not group master process. To fix
197: this bug, SIGINJECT signal is not sent by child process but by control thread
198: in parent process;
199: - minor bug is fixed in data injection (POKE) that does not work as expected
200: when child process is protected by NRPROC.
201: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
202: - --enable-sysv-sems is added to configure script to use SystemV semaphores
203: functions instead of POSIX functions. This function is disabled or forced on
204: systems that does not provide correct POSIX or SysV semaphores subsystem;
205: - a dirty but not quick patch is written to workaround broken siginfo
206: structures. This patch has been successfully tested. It uses a segment of
207: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
208: (Unix PID);
209: - some OpenBSD's hacks are added;
210: - broken siginfo->si_pid field is now checked by configure script;
211: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

219: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
220: - TOKENIZE is now able to convert escape sequences;
221: - ATPOKE and CLRATPOKE new intrinsics are added;
222: - --enable-full-static configure flag is added. With this flag, mysql and
223: postgresql libraries are statically linked in rpl executable;
224: - units Makefile is modified to avoid readline and ncurses usages;
225: - sqlite is upgraded to 3.7.0.1;
226: - units is upgraded to 1.88;
227: - another major bug is fixed in the same variable creation subroutine.
228: Level 0 and 1 variables adresses were swapped when a global variable masked
229: a name of RPL/2 routine;
230: - major bug is fixed in global variable creation subroutine. When a global
231: variable was created and when a local variable existed with the same name,
232: computed address of global variable was wrong;
233: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
234: is forced in front of all libraries.
235: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
236: - BACKTRACE intrinsic is added;
237: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
238: when this structure is included in IFERR/THEN/END structure and when an error is
239: caught;
240: - major bug is fixed in analyse() subroutine. When evaluation() returned error
241: in a compiled program, analyse() caught this error twice and randomly aborted
242: with a segmentation error;
243: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
244: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
245: signals;
246: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
247: matrix.
248: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
249: - minor bug is fixed in evaluation() subroutine. With this patch, same program
250: returns same result with or without -p flag;

252: - openssl is upgraded to 1.0.0a;
253: - interrupt stacks are now FIFO instead of LIFO;
254: - debug memory allocation subroutines are improved to run in multithreaded
255: programs;
256: - some memory leaks are fixed in process management (SPAWN and DETACH);
257: - version verification is added to shared objects;
258: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
259: linux (false mremap() prototype);
260: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
261: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
262: - all '-' are replaced by '_' in random generator list;

266: format in FCH (file descriptor) and SCK (socket descriptor);
267: - debug routines are improved;
268: - PROCID is added;
269: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
270: and to not use swap;
271: - major bug is fixed in sql support. SQL connections were closed in all chield
272: process;
273: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
274: discovered in Solaris thread safe allocators (libmalloc and libumem) that
275: are first fit class allocators. Solaris libmtmalloc works better and is
276: a best fit class allocator but its performance is poor than ptmalloc3
277: performance;
278: - major bug is fixed in ROW+ intrinsic (new row was not added where it
279: should);
280: - minor bugs are fixed in interruptions.c (semaphores values when error is
281: caught);
282: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
283: created by SPAWN;
284: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
285: ATEXIT. If it receives SIGFABORT, it does not;
286: - ONEXIT is renamed in ATEXIT;
287: - ONEXIT new intrinsic is added.

293: information about shared variable was not copied to new processus structure;
294: - some little memory leaks are fixed in evaluation(), recherche_type() and
295: sequenceur(). They only occured when syntax error were caught;
296: - IMPLICIT causes execution error instead system error;
297: - Hurd support is improved but currently broken because Hurd does not support
298: SIG_INFO. Work in progress;
299: - OpenBSD specific support is removed from sources;
300: - support for Mac OS X and Windows/Cygwin is added.

352: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
353: each execution (md5 and sha1 sums) to enhance security. If one of these tools
354: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
355: on a non recoverable system error;
356: - openssl and sqlite3 libraries are added;
357: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this

385: Number of scalar operations per second and per core : 2383016
386:
387: - PULPRFL does not abort on BUG() but on execution error;
388: - TRIM, REPL and TOKENIZE are added;
389: - sockets options are now set before bind();
390: - shutdown() is added to all connected sockets;
391: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
392: list argument and inexistant elements).
393: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
394: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
395: signals sent to main process were not caught because DAEMON did not replace
396: old pid by new one;
397: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
398: evaluation when an error is reported from a subroutine in another subroutine.
399: For example, error was not caught in following program when it is executed with
400: -p option :
401: TEST << iferr TEST2 then end >>
402: TEST2 << 0 inv >>
403: - major bug is fixed in variable management. Some local variables were
404: seen as global ones;
405: - major bug is fixed in rplcore. Rplcore entered in dead lock when
406: script file contains a multibyte character;
407: - IN intrinsic is added;
408: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
409: returned false ;
410: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
411: programs;
412: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
413: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
414: strings were never closed;
415: - some bugs have been fixed in file management;
416: - RPL/2 can now be run on EBCDIC systems (OS/390);
417: - major bug is fixed in -A command line option (NULL character is missing);
418: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
419: made by blocks (1024 bytes). When an incomplete multibyte sequence is
420: encountered at end of block, subroutine aborts with an execution error;
421: - major bug is fixed in OPEN (TCP/IPv4 sockets).
422: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
423: - DISP now locks stdout;
424: - rpliconv is added to replace standard iconv provided by operating system.
425: Indeed, conversion between different encodages requires transliteration
426: that is not offered by some iconv utility;
427: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
428: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
429: not be found), SYSEVAL enters in a dead lock;
430: - fprintf is replaced by some functions that allow transliterations between
431: locales;
432: - '"' can now be used in strings ("\"");
433: - iconv is called with -c in preprocessor stage. It is done to write
434: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
435: - double free is fixed in liberation() (type SQL, only occurs when locale is
436: set);
437: - LOCALIZATION, UCASE and LCASE are added;
438: - major bug is fixed in EXIT intrinsic that was able to return a false
439: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
440: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
441: used in onLoading from shared library, USE was pushed on stack as algebraic
442: expression;
443: - libiconv is upgraded to 1.13.1;
444: - gnuplot is upgraded to 4.2.6;
445: - gsl is upgraded to 1.13.
446: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
447: - pipe() is overwritten by a macro to avoid a system error. Communication
448: between process are done with pipes and these pipes are managed by a
449: specific asynchrone thread. If a script try to create more threads than
450: management thread can destroy, you can quickly achieve maximum number of
451: opened files and pipe() shall return a system error. This macro tries to create
452: pipes. If pipe() function returns an error, macro waits and retries. If
453: number of retries is greater than a hardcoded value, macro returns an error;
454: - major bug (deadlock) is fixed in process and thread management. I hope
455: this bug shall be the last one;
456: - major bug is fixed in DET intrinsic (determinant was computed without LU
457: diagonalization);
458: - SWAPCNTXT is added;
459: - minor bug is fixed in Makefile.am (licences rule).
460: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
461: - some bugfixes are added in process management;
462: - all process management is rewritten to avoid usage of defunct process
463: or thread number;
464: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
465: was called before a pending interruption5 (SIGFSTOP), signal handler uses
466: a freed semaphore and corrupts heap;
467: - CLRERR is added to erase previous errors;
468: - ERRN and ERRM return exception message and number;
469: - major bug is fixed in interruptions.c. All signal are now bufferised
470: when semaphore_liste_threads is null to avoid deadlock. This bug only
471: occured when STOP was sent to a dying thread or process (when this thread or
472: process was running retrait_thread());
473: - matrix rank is computed before matrix inversion;
474: - file locks are added to stdin and stdout. stderr is not locked because
475: all messages written by signal handlers are sent to stderr;
476: - configure.in script is modified to test gcc version and avoid a bug in
477: gcc older than 4.4;
478: - some benchmarks have been done :

507: -Wno-unused-parameter;
508: - all mathematical exceptions are now signaled by exceptions instead of
509: execution error;
510: - minor bug is fixed in both CSTOP and RSTOP intrinsics. Without this fix, you
511: can call twice CSTOP without RSTOP;
512: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
513: SMPHRTRYDECR, SMPHGETV).
514: * Fri Jul 24 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.4 (RPL/2)

516: signal is sent to a dying thread. Some mutexes are replaced by semaphores too
517: to be used in signal handlers;
518: - major bug (memory corruption) is fixed in COL- intrinsic;
519: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a
520: software interrupt was caught;
521: - rplpp man page is added.
522: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
523: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
524: process termination);

534: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
535: - FORTRAN 77 file management subroutines are rewritten in pure C due to
536: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
537: in some cases (gcc/gfortran/libc/OS and arch conjonction);
538: - a memory leak is fixed in REMOVE intrinsic;
539: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
540: and due to a libmysqlclient that is not thread safe).

547: - --enable-profile flag is added to configure script. When this flag is
548: enabled, rpl is built with -pg option;
549: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
550: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
551: process is killed;
552: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
553: know typeof() intrinsic function. This function is not standard but exists
554: under Sun Studio, gcc, and maybe some others compilers. If this function does
555: not exist on your compiler, you can change its definition by old one in
556: src/rpl.h;

579: deadlock when a huge amount of threads is launched);
580: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
581: arguments types are unsupported;
582: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All

597: static variable that is shared by multiple threads;
598: - '->' intrinsic is improved. All object copies have been avoided;
599: - -n flag is added to catch HUP signal. stderr and stdout are redirected
600: to a file, stdin is redirected to /dev/null when control process is killed;
601: - a mutex is added to each object (before this modification,
602: RPL/2 used a global mutex and performances in multithreaded programs were very
603: poor.);

617: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
618: that all programs that worked with old SQL intrinsic can now work with
619: SQLQUERY. With all new programs, you can open a real connection to databases;
620: - NRPROC is added. This new intrinsic is used to catch error from child
621: process. Without NRPROC, any errors returned by child process cause
622: main process to abort;
623: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
624: starts a new process). There are no mutexes in RPL/2 because all spawned process
625: use specific context. Nevertheless, shared variables and associated mutexes
626: should be added;

713: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
714: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
715: workaround for this major bug. Nevertheless, all others capabilities seems to
716: work fine;
717: - '->' is modified to return error when program tries to initialiaze two

751: - minor bug is fixed in STR->. STR-> could return a system error instead an
752: execution one;
753: - first bug due to new garbage collector is fixed in '+' ({ } { } +) and in
754: '-' intrinsics;
755: - PostgreSQL support is written.

758: { "mysql:iso-8859-1" "server" "database" ... };
759: - major bug is fixed un analyse_algebrique(). When DISP printed an algebraic
760: object, 'DISP()' was pushed in stack;
761: - same major bug is fixed in <, >, <=, >= and <>;
762: - major bug fixed in formateur() (segfault when a symbol is used without "'");
763: - major bug is fixed in DUPN intrinsic;
764: - when software interrupt (SWI) is evaluated, SWI pushs process id on stack
765: before starting interrupt evaluation;
766: - -f parameter is added when iconv is called;
767: - as old file program was bugged, a new option is added to configure script.
768: When configure is called with --disable-encoding-autodetection, make does not
769: try to detect source encoding. Please, do not use if RPL/2 can be built
770: without this option !
771: - new garbage collector (and more efficient) is written;
772: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
773: not support real time signals, RPL/2 cannot use multitasking functions;
774: - error returned by preprocessor are now catched by RPL/2;
775: - -p option is added. With this option, all scripts are compiled before
776: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
777: 40% faster;

923: it tries to launch regular gnuplot;
924: - gnuplot is added to source tree to avoid some trouble between preinstalled
925: gnuplot and release used by RPL/2. This addition to source tree is

974: With STATIC, next variables created by '->' are static;
975: - PROTECT and UNPROTECT are added to protect variables against write
976: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
977: versions of PROTECT and UNPROTECT that only deal with global variables
978: (see RCL/SAVE);
979: - variable management routines have been rewritten. The new ones are
980: uncompatible with the old ones. Before these changes, a local variable
981: was exported to a child subroutine, but cannot be modified into this
982: child subroutine. Now, a local variable is accessible only in its subroutine;
983: - SAVE intrinsic is added to manipulate global variables;

1304: fine...);
1305: - NOT is not correctly formatted in formateur.c:
1306: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1307: with a NOTZ function !
1308: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1311: - RPL/2 is tested with efence and valgrind;
1312: - configure.in script is modified;
1313: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1374: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1375: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1376: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1393: - SCLS is added;
1394: - DRWS now uses COLS to draw 2D graphics;
1395: - PPAR and SPAR are written. SPAR returns a list that contains the
1396: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1397: statistical variable, or "DISABLED" if its type is not one of the type of
1398: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1399: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1400: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1401: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1402: disabled. Arguments of EXTERNAL are case sensitive because the external
1403: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1404: of known external functions but add the new list to the last. { "all" }
1405: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1406: external names of the known functions;
1407: - mkrplso.in is modified.
1408: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1409: - vim syntax file is upgraded;
1410: - a minor mistake is fixed in recherche_instruction_suivante();

1421: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1422: VISIT does not find a name in level 1;
1423: - configure.in script is modified to add a new test (--enable-debug
1424: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1425: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1426: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1427: 'MATRIX' { 2 2 3 } GETR;
1428: - LOGSCALE intrinsic is improved and now, it can be used as
1429: { "main" "auxiliary" X Y } LOGSCALE;
1430: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1431: same than AXES:
1432: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1433: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1434: { { -10 10 } "automatic" } SCALE.
1435: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1436: because it changes only the dimension of the screen. To have a logarithmic
1437: scale, you must use LOGSCALE intrinsic:
1438: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1439: screen on second scale;
1440: - { X X } autoscale and { Y Y } logscale are now invalid;
1441: - *D is added (depth multiplication, for 3D graphics);
1442: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1443: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1444: - a major bug is fixed in GETI instrinsic when it is used with a name
1445: that contains a matrix or a vector (bad upper bounds conditions in
1446: incrementation);
1447: - DISP intrinsic now uses the 33-th flag. When it is not set
1448: (default), a final carriage return is sent to the terminal;
1449: - AXES intrinsic only takes a list that can contains the keywork
1450: "main" or "auxiliary". Before this modification, this keyword was in
1451: the first stack level;
1452: - vim syntax file is upgraded;
1453: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1454: option;
1455: - LAST is now disabled in the main loop of INT intrinsic;
1456: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1457: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1458: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1459: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1460: in 0);
1461: - LAST is disabled in the main loop of DRAW intrinsic;
1462: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1463: evaluation of an equation, the system stack is returned corrupted to the
1464: sequencer;
1465: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1466: of a loop are not integer or real.
1467: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1468: - the compilation stage aborts with an error message when two definitions
1469: have the same name. To improve the compilation() subroutine, I have to
1470: add some tests in gestion_variables.c;
1471: - recherche_type() subroutine ad some other connex subroutines are improved.
1472: Now, some syntax errors about object are caught and do not perform sequencer
1473: hangup;
1474: - readline is upgraded (minor compilation bug with recent gcc);
1475: - Makefile.am's and configure.in scripts are improved.
1476: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1477: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1478: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1479: the boxwidth, 1 by default);
1480: - recherche_type() is rewritten to be faster;
1481: - gsl is upgraded (release 1.3);
1482: - ncurses is upgraded and patched (release 5.3);
1483: - recherche_instruction_suivante() is fixed (string research with included
1484: '"') and rewritten to be faster;
1485: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1486: segfault.
1487: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1495: - a minor bug is fixed in evaluation subroutine;
1496: - vim syntax file is improved;
1497: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1498: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1499: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1500: is a quick and dirty workaround...);
1501: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1502: - rplconvert is improved.
1503: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
