44: Number of scalar operations per second and per core : 3809121.83444626
45: schroedinger:[~/cvs/bench] >
1.99 bertrand 46: - recherche_type() did not convert huge integer in real. Now,
47: 18446744072742037448 is converted into real as value cannot be stored in

53: a real copy. Now, struct_mutex contains locks owner. On Linux or Solaris (for
54: example), it is possible to lock mutex from a thread and unlock the same mutex
55: from another thread. On NetBSD, system crashes.

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

154: Known escape sequences are \", \b, \n, \t, \x?? and \\.
1.60 bertrand 155: * Sun Mar 06 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
156: - Ncurses is upgraded to 5.8;
157: - ALARM is fixed by filling isdst field;
158: - catch ECONNRESET in write intrinsic to return an execution error instead of
159: system one;
160: - fix a typo in HELP intrinsic;
161: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2;
1.57 bertrand 162: - Lapack is upgraded to 3.3.0;
1.58 bertrand 163: - libmtmalloc is now default Solaris allocator;
1.56 bertrand 164: - ncurses is upgraded;
1.60 bertrand 165: - regression introduced by 4.0.19 is fixed in signal management.
1.59 bertrand 166: Interruption1() could be called from itself and raises bus error (on sparc) or
1.55 bertrand 167: segmentation fault;
168: - sqlite is upgraded to 3.7.4;
1.54 bertrand 169: - OpenSSL is upgraded to 1.0.0c;
170: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);

1.53 bertrand 172: - gnuplot is upgraded to 4.4.2 due to major bugs.
1.52 bertrand 173: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
174: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
175: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
176: corruption. As internal memory management have been improved, a best fit
177: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 178: - gnuplot is upgraded to 4.4.1;
179: - deadlock is fixed in signal handlers: same mutex was used in standard
180: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
181: and signal handlers. A new signal handler specific mutex is added;
182: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
183: that has to be evaluated by ->NUM;
1.49 bertrand 184: - rplfile build process is modify to be sure that rplfile is not modified
185: after rpl build stage (to be sure that rplfile checksum is not modified after
186: rpl compilation);
1.51 bertrand 187: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
188: modified to remove yacc code and renamed;
1.47 bertrand 189: - some workarounds have been written to not use buggy klibc SystemV IPCS.
190: ABORT now works on eComStation;
191: - sqlite is upgraded to 3.7.2;
192: - bug is fixed in software interrupts. When both process have different PID,
193: parent process was not interrupted if it is not group master process. To fix
194: this bug, SIGINJECT signal is not sent by child process but by control thread
195: in parent process;
1.46 bertrand 196: - minor bug is fixed in data injection (POKE) that does not work as expected
197: when child process is protected by NRPROC.
1.44 bertrand 198: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 199: - --enable-sysv-sems is added to configure script to use SystemV semaphores
200: functions instead of POSIX functions. This function is disabled or forced on
201: systems that does not provide correct POSIX or SysV semaphores subsystem;
202: - a dirty but not quick patch is written to workaround broken siginfo
203: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 204: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 205: (Unix PID);
1.41 bertrand 206: - some OpenBSD's hacks are added;
207: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 208: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
209: - random generator is cloned by SPAWN;
210: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
1.39 bertrand 211: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 212: or freeaddrinfo;
1.39 bertrand 213: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
214: - major bug is fixed in CHR intrinsic when obtained character is not printable;
215: - Lapack is upgraded to 3.2.2;
1.37 bertrand 216: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
1.36 bertrand 217: - TOKENIZE is now able to convert escape sequences;
218: - ATPOKE and CLRATPOKE new intrinsics are added;
219: - --enable-full-static configure flag is added. With this flag, mysql and
220: postgresql libraries are statically linked in rpl executable;
221: - units Makefile is modified to avoid readline and ncurses usages;
1.37 bertrand 222: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 223: - units is upgraded to 1.88;
224: - another major bug is fixed in the same variable creation subroutine.
225: Level 0 and 1 variables adresses were swapped when a global variable masked
226: a name of RPL/2 routine;
1.35 bertrand 227: - major bug is fixed in global variable creation subroutine. When a global
228: variable was created and when a local variable existed with the same name,
229: computed address of global variable was wrong;
230: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
231: is forced in front of all libraries.
1.34 bertrand 232: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
233: - BACKTRACE intrinsic is added;
234: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
235: when this structure is included in IFERR/THEN/END structure and when an error is
236: caught;
237: - major bug is fixed in analyse() subroutine. When evaluation() returned error
238: in a compiled program, analyse() caught this error twice and randomly aborted
239: with a segmentation error;
240: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
241: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
242: signals;
243: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
244: matrix.
1.33 bertrand 245: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
246: - minor bug is fixed in evaluation() subroutine. With this patch, same program
247: returns same result with or without -p flag;
248: - ncurses 5.7 is upgraded to 20100619;
249: - openssl is upgraded to 1.0.0a;
1.32 bertrand 250: - interrupt stacks are now FIFO instead of LIFO;
251: - debug memory allocation subroutines are improved to run in multithreaded
252: programs;
253: - some memory leaks are fixed in process management (SPAWN and DETACH);
254: - version verification is added to shared objects;
255: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
256: linux (false mremap() prototype);
257: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
1.30 bertrand 258: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
1.29 bertrand 259: - all '-' are replaced by '_' in random generator list;

261: - major bug is fixed in IFERR structure. Only occurs in compiled program;
262: - major bug is fixed in copie_objet() and liberation(). Only concerns
263: format in FCH (file descriptor) and SCK (socket descriptor);
264: - debug routines are improved;
265: - PROCID is added;
266: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
267: and to not use swap;
1.26 bertrand 268: - major bug is fixed in sql support. SQL connections were closed in all chield
269: process;
270: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
271: discovered in Solaris thread safe allocators (libmalloc and libumem) that
272: are first fit class allocators. Solaris libmtmalloc works better and is
273: a best fit class allocator but its performance is poor than ptmalloc3
274: performance;
1.24 bertrand 275: - major bug is fixed in ROW+ intrinsic (new row was not added where it
276: should);
277: - minor bugs are fixed in interruptions.c (semaphores values when error is
278: caught);
279: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
280: created by SPAWN;
281: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
282: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 283: - ONEXIT is renamed in ATEXIT;
284: - ONEXIT new intrinsic is added.
1.20 bertrand 285: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
286: - major bug is fixed in static and shared variables initialization subroutine.
287: This bug only occurs when RPL/2 tries to create a shared or static variable
288: from an expression;
289: - major bug is fixed in copie_etat_processus(). A field that contains
290: information about shared variable was not copied to new processus structure;
1.19 bertrand 291: - some little memory leaks are fixed in evaluation(), recherche_type() and
292: sequenceur(). They only occured when syntax error were caught;
293: - IMPLICIT causes execution error instead system error;
294: - Hurd support is improved but currently broken because Hurd does not support
295: SIG_INFO. Work in progress;
296: - OpenBSD specific support is removed from sources;
297: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 298: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

1.15 bertrand 334: - -a command line option analyzes program (structure and syntax) and
335: sends preprocessor output to standard output. This option is used by
336: rplc (RPL/2 compiler).
1.13 bertrand 337: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
338: - in formatted file, string format returned a variable length string even if
339: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 340: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 341: - keyed access files support is added. Currently, only formatted files are
342: supported;
343: - direct access files support is added. Currenlty, these files can only be used
344: in formatted mode;
345: - virtual variables are now writte in UTF-8 and all special characters
346: in string are escaped;

352: on a non recoverable system error;
353: - openssl and sqlite3 libraries are added;
354: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
355: variable indicates RPL/2 root directory. If it is not set, root path
356: is given by configure script (d_exec_path);
1.11 bertrand 357: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

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

547: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
548: process is killed;
549: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
550: know typeof() intrinsic function. This function is not standard but exists
551: under Sun Studio, gcc, and maybe some others compilers. If this function does

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

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

764: - as old file program was bugged, a new option is added to configure script.
765: When configure is called with --disable-encoding-autodetection, make does not
766: try to detect source encoding. Please, do not use if RPL/2 can be built
767: without this option !
768: - new garbage collector (and more efficient) is written;
769: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
770: not support real time signals, RPL/2 cannot use multitasking functions;

772: - -p option is added. With this option, all scripts are compiled before
773: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
774: 40% faster;
775: - read and write operations in pipe() are rewritten to be sure that such
776: operations are atomic;
777: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

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

1301: fine...);
1302: - NOT is not correctly formatted in formateur.c:
1303: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1304: with a NOTZ function !
1305: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1308: - RPL/2 is tested with efence and valgrind;
1309: - configure.in script is modified;
1310: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1371: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1372: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1373: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1390: - SCLS is added;
1391: - DRWS now uses COLS to draw 2D graphics;
1392: - PPAR and SPAR are written. SPAR returns a list that contains the
1393: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1394: statistical variable, or "DISABLED" if its type is not one of the type of
1395: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1396: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1397: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1398: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1399: disabled. Arguments of EXTERNAL are case sensitive because the external
1400: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1401: of known external functions but add the new list to the last. { "all" }
1402: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1403: external names of the known functions;
1404: - mkrplso.in is modified.
1405: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1406: - vim syntax file is upgraded;
1407: - a minor mistake is fixed in recherche_instruction_suivante();

1418: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1419: VISIT does not find a name in level 1;
1420: - configure.in script is modified to add a new test (--enable-debug
1421: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1422: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1423: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1424: 'MATRIX' { 2 2 3 } GETR;
1425: - LOGSCALE intrinsic is improved and now, it can be used as
1426: { "main" "auxiliary" X Y } LOGSCALE;
1427: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1428: same than AXES:
1429: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1430: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1431: { { -10 10 } "automatic" } SCALE.
1432: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1433: because it changes only the dimension of the screen. To have a logarithmic
1434: scale, you must use LOGSCALE intrinsic:
1435: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1436: screen on second scale;
1437: - { X X } autoscale and { Y Y } logscale are now invalid;
1438: - *D is added (depth multiplication, for 3D graphics);
1439: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1440: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1441: - a major bug is fixed in GETI instrinsic when it is used with a name
1442: that contains a matrix or a vector (bad upper bounds conditions in
1443: incrementation);
1444: - DISP intrinsic now uses the 33-th flag. When it is not set
1445: (default), a final carriage return is sent to the terminal;
1446: - AXES intrinsic only takes a list that can contains the keywork
1447: "main" or "auxiliary". Before this modification, this keyword was in
1448: the first stack level;
1449: - vim syntax file is upgraded;
1450: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1451: option;
1452: - LAST is now disabled in the main loop of INT intrinsic;
1453: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1454: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1455: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1456: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1457: in 0);
1458: - LAST is disabled in the main loop of DRAW intrinsic;
1459: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1460: evaluation of an equation, the system stack is returned corrupted to the
1461: sequencer;
1462: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1463: of a loop are not integer or real.
1464: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1466: have the same name. To improve the compilation() subroutine, I have to
1467: add some tests in gestion_variables.c;
1468: - recherche_type() subroutine ad some other connex subroutines are improved.
1469: Now, some syntax errors about object are caught and do not perform sequencer
1470: hangup;
1471: - readline is upgraded (minor compilation bug with recent gcc);
1472: - Makefile.am's and configure.in scripts are improved.
1473: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1474: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
