466: - major bug is fixed in STD format (1E7 sq prints 1);
467: - major bug is fixed in READ intrinsic (socket). This bug was introduced
468: by a new feature in glibc.
469: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
470: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
471: "ALL" IMPLICIT when it runs in interactive mode;
472: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
473: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
474: to use SAVE to manipulate global variables;
475: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
476: subroutines;
477: - fix major memory access violation in evaluation subroutine. Only occurs
478: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
479: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
480: when X was a vector or a table.

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

531: this bug, SIGINJECT signal is not sent by child process but by control thread
532: in parent process;
533: - minor bug is fixed in data injection (POKE) that does not work as expected
534: when child process is protected by NRPROC.
535: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
536: - --enable-sysv-sems is added to configure script to use SystemV semaphores
537: functions instead of POSIX functions. This function is disabled or forced on
538: systems that does not provide correct POSIX or SysV semaphores subsystem;
539: - a dirty but not quick patch is written to workaround broken siginfo
540: structures. This patch has been successfully tested. It uses a segment of
541: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
542: (Unix PID);
543: - some OpenBSD's hacks are added;
544: - broken siginfo->si_pid field is now checked by configure script;

562: Level 0 and 1 variables adresses were swapped when a global variable masked
563: a name of RPL/2 routine;
564: - major bug is fixed in global variable creation subroutine. When a global
565: variable was created and when a local variable existed with the same name,
566: computed address of global variable was wrong;
567: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
568: is forced in front of all libraries.

570: - BACKTRACE intrinsic is added;
571: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
572: when this structure is included in IFERR/THEN/END structure and when an error is
573: caught;
574: - major bug is fixed in analyse() subroutine. When evaluation() returned error
575: in a compiled program, analyse() caught this error twice and randomly aborted
576: with a segmentation error;
577: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
578: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
579: signals;
580: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
581: matrix.

603: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
604: and to not use swap;
605: - major bug is fixed in sql support. SQL connections were closed in all chield
606: process;
607: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
608: discovered in Solaris thread safe allocators (libmalloc and libumem) that
609: are first fit class allocators. Solaris libmtmalloc works better and is
610: a best fit class allocator but its performance is poor than ptmalloc3
611: performance;
612: - major bug is fixed in ROW+ intrinsic (new row was not added where it
613: should);
614: - minor bugs are fixed in interruptions.c (semaphores values when error is
615: caught);
616: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
617: created by SPAWN;

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

688: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
689: on a non recoverable system error;
690: - openssl and sqlite3 libraries are added;
691: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this

729: signals sent to main process were not caught because DAEMON did not replace
730: old pid by new one;
731: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
732: evaluation when an error is reported from a subroutine in another subroutine.
733: For example, error was not caught in following program when it is executed with

768: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
769: - double free is fixed in liberation() (type SQL, only occurs when locale is
770: set);
771: - LOCALIZATION, UCASE and LCASE are added;
772: - major bug is fixed in EXIT intrinsic that was able to return a false
773: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
774: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
775: used in onLoading from shared library, USE was pushed on stack as algebraic
776: expression;
777: - libiconv is upgraded to 1.13.1;
778: - gnuplot is upgraded to 4.2.6;
779: - gsl is upgraded to 1.13.
780: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
781: - pipe() is overwritten by a macro to avoid a system error. Communication
782: between process are done with pipes and these pipes are managed by a
783: specific asynchrone thread. If a script try to create more threads than
784: management thread can destroy, you can quickly achieve maximum number of
785: opened files and pipe() shall return a system error. This macro tries to create
786: pipes. If pipe() function returns an error, macro waits and retries. If
787: number of retries is greater than a hardcoded value, macro returns an error;
788: - major bug (deadlock) is fixed in process and thread management. I hope
789: this bug shall be the last one;
790: - major bug is fixed in DET intrinsic (determinant was computed without LU
791: diagonalization);
792: - SWAPCNTXT is added;
793: - minor bug is fixed in Makefile.am (licences rule).
794: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
795: - some bugfixes are added in process management;
796: - all process management is rewritten to avoid usage of defunct process
797: or thread number;
798: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
799: was called before a pending interruption5 (SIGFSTOP), signal handler uses
800: a freed semaphore and corrupts heap;
801: - CLRERR is added to erase previous errors;
802: - ERRN and ERRM return exception message and number;
803: - major bug is fixed in interruptions.c. All signal are now bufferised
804: when semaphore_liste_threads is null to avoid deadlock. This bug only
805: occured when STOP was sent to a dying thread or process (when this thread or
806: process was running retrait_thread());
807: - matrix rank is computed before matrix inversion;
808: - file locks are added to stdin and stdout. stderr is not locked because
809: all messages written by signal handlers are sent to stderr;
810: - configure.in script is modified to test gcc version and avoid a bug in
811: gcc older than 4.4;
812: - some benchmarks have been done :

884: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
885: process is killed;
886: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
887: know typeof() intrinsic function. This function is not standard but exists
888: under Sun Studio, gcc, and maybe some others compilers. If this function does
889: not exist on your compiler, you can change its definition by old one in
890: src/rpl.h;
891: - fflush() can now be interrupted by signal (SunOS);
892: - fflush(NULL) is called before all fork() occurrences;

913: deadlock when a huge amount of threads is launched);
914: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
915: arguments types are unsupported;
916: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
917: data are buffered. PLOT is used to draw these objects.);
918: - MARK instrinsic is added;
919: - new allocator mechanism is written;
920: - some regression bugs have been fixed, some memory leaks too.
921: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)

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

952: that all programs that worked with old SQL intrinsic can now work with
953: SQLQUERY. With all new programs, you can open a real connection to databases;
954: - NRPROC is added. This new intrinsic is used to catch error from child
955: process. Without NRPROC, any errors returned by child process cause
956: main process to abort;
957: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
958: starts a new process). There are no mutexes in RPL/2 because all spawned process
959: use specific context. Nevertheless, shared variables and associated mutexes
960: should be added;
961: - -D flag and DAEMONIZE intrinsic have been added;
962: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

1046: - FUSE, RFUSE and CLRFUSE have been added;
1047: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
1048: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
1049: workaround for this major bug. Nevertheless, all others capabilities seems to
1050: work fine;
1051: - '->' is modified to return error when program tries to initialiaze two

1099: before starting interrupt evaluation;
1100: - -f parameter is added when iconv is called;
1101: - as old file program was bugged, a new option is added to configure script.
1102: When configure is called with --disable-encoding-autodetection, make does not

1104: without this option !
1105: - new garbage collector (and more efficient) is written;
1106: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1107: not support real time signals, RPL/2 cannot use multitasking functions;
1108: - error returned by preprocessor are now catched by RPL/2;
1109: - -p option is added. With this option, all scripts are compiled before
1110: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run

1142: than 1E6;
1143: - numeric and character formats are now tested;
1144: - -A flag is added. -A is used to give command line parameters to main
1145: routine. Example:

1157: - minor bug (segfault) is fixed in encart() routine (splash screen). Child
1158: process ended with segfault due to a mistake in Motif widget cleaning
1159: process;
1160: - major bug is fixed in DETACH intrinsic. Child process were locked when
1161: they were started with a locked mutex that comes from its father;

1168: - socket support (Unix, IPv4, IPv6, STREAM, DATAGRAM, ROBUST DATAGRAM,
1169: SEQUENTIAL DATAGRAM, RAW) is added. Warning: IPv6 sockets have not been tested
1170: because I don't have any IPv6 compliant server, but they should work.
1171: * Mon Sep 10 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.1 (RPL/2)
1172: - library management is rewritten from scratch. EXTERNAL is removed and
1173: EXTERNALS is added. Now, all exported symbols are sent to RPL/2 when
1174: library is loaded;
1175: - OPEN arguments are changed;
1176: - EXTERNAL now checks availability of external functions;
1177: - number of arguments is verified in analyse_algebrique().
1178: 'SIN(A+X,2)' is now refused because SIN requires only one argument;
1179: - all but lapack symbols are exported from librpl with librpl, f77 or f90
1180: prefix;
1181: - minor bug is fixed in formateur() (AND and OR requires parenthesis);

1192: - major bug is fixed in tex.h (multiline strings);
1193: - examples subdir is added;
1194: - major bug is fixed in recherche_variable(). When an expression is evaluated
1195: in a function, all variables set in this function must be visible in
1196: expression. Thus, << I -> 3 << << I >> eval >> must return 3, not 'I';
1197: - LAST stack is saved in rplcore;
1198: - major bug is fixed in ->HMS. It only occurs when argument type is not
1199: integer or real;
1200: - major bug (segfault) is fixed when rpl is called with empty file;
1201: - libtool support is removed. Two new scripts (rplc and rpllink) are provided

1218: - gnuplot does not have to be built if --disable-embedded-gnuplot is set;
1219: - new prompt ("RPL/2> ") is used for interactive mode;
1220: - ARCCOS, ARCSIN, ARCTG, ARGCH, ARGSH, ARGTH, CH, SH, TH and TG intrinsics
1221: are removed, because all of these intrinsics have two forms. ARCCOS is
1222: the same than ACOS, TAN=TG, COSH=CH. Please adapt your scripts;
1223: - gnuplot compilation does not have to be done when disable-gnuplot is set;
1224: - major bug is fixed in RECV that avoid usage of multitasking.
1225: * Tue Jul 10 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.00pre8w (RPL/2)
1226: - False error (system error) was reported by recherche_type();
1227: - recherche_type() returns syntax error if a list is included in
1228: an algebraic expression;
1229: - --enable-debug is modified. Now, return can be defined to print
1230: on stdout its position in source code (line and function);
1231: - minor bug is fixed in recherche_type(). Don't forget that space
1232: are not significant in algebraic expression:
1233: '12 3+ 12 X' is the same expression than '123+12X';
1234: - src/Makefile.am is modified to avoid double compilation process;
1235: - --enable-final-run-path is added to configure.in script;
1236: - STATIC is modified to declare static variables in expression. Warning: static
1237: variables used in expressions are deleted when evaluation of this expression
1238: ends;
1239: - MEM does not report static variable sizes;
1240: - minor bug is fixed in HELP intrinsic. When the last instruction was not
1241: known, HELP function was pushed in operational stack. HELP did not work
1242: when there were space on input line.
1243: * Mon May 28 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.00pre8v (RPL/2)
1244: - DATE is modified: reduced julian days is replaced by fraction part

1251: - intrinsic functions are case sensitive. External functions are case
1252: unsensitive. A minor bug is fixed in recherche_type() because all external
1253: functions were case unsensitive when they were evaluated from RPN expressions;
1254: - HELP function is rewritten to be more friendly (a la OpenVMS);
1255: - external wrapper (rplplot) is written to force usage of gnuplot provided
1256: by RPL/2 if it is built during build process. If this build does not exist,
1257: it tries to launch regular gnuplot;
1258: - gnuplot is added to source tree to avoid some trouble between preinstalled
1259: gnuplot and release used by RPL/2. This addition to source tree is
1260: required by some incompatibility between gnuplot releases;
1261: - Lapack is upgraded to 3.1.1 release;
1262: - GSL is upgraded to 1.9 revision;
1263: - RPL_TMP_PATH env variable is added to specify the path of tempfiles. If
1264: it is not set, /tmp is used. If /tmp is not writable, /var/tmp is used. If
1265: not, ./ but RPL/2 can hang with a fatal error if this last location is
1266: not writable;
1267: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1268: error scrutation.
1269: * Sat Mar 24 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.00pre8u (RPL/2)

1276: SYSEVAL;
1277: - graphic and PostScript outputs are now cleared in child process;
1278: - locales are now used by preprocessor;
1279: - major bug is fixed in impression_tex(). PRINT did not work due to a bug
1280: introduced by multitasking code;
1281: - SORT can now use name as its argument.
1282: * Sun Jan 21 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.00pre8t (RPL/2)
1283: - Variable management has been rewritten and some tests have been done. Now,
1284: it is possible to execute:
1285:
1286: #!/usr/local/bin/rpl -sc
1287:
1288: TEST
1289: <<
1290: 1 1000 start VAR_S VAR_S2 next

1292:
1293: VAR_S
1294: <<
1295: static 3 -> C << C disp 'C' incr if C 10 > then 'C' volatile end >>
1296: >>
1297:

1307: static variable can be transformed into volatile with VOLATILE.
1308: With STATIC, next variables created by '->' are static;
1309: - PROTECT and UNPROTECT are added to protect variables against write
1310: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1311: versions of PROTECT and UNPROTECT that only deal with global variables
1312: (see RCL/SAVE);
1313: - variable management routines have been rewritten. The new ones are
1314: uncompatible with the old ones. Before these changes, a local variable
1315: was exported to a child subroutine, but cannot be modified into this
1316: child subroutine. Now, a local variable is accessible only in its subroutine;
1317: - SAVE intrinsic is added to manipulate global variables;
1318: - SUSPEND is written. RPL/2 waits for a SIGCONT signal;
1319: - SORT, COL->, ->COL, ROW->, ROW-> intrinsics are written;

1354: multithreading. DETACH, SEND and RECV now use four real time signals to
1355: perform a better task synchronization;
1356: - some bugs introduced by locales specific compilations are fixed;
1357: - major memory corruption is fixed in DEPND;
1358: - HELP intrinsic is modified to print a classified output.

1369: - major bug is fixed in evaluation() subroutine. Value of error flag
1370: was not returned in some cases;
1371: - FACT intrinsic does not accept real arguments anymore due to the new intrinsic
1372: GAMMA;
1373: - GAMMA intrinsic is added (complex function) ;
1374: - autoconf/automake scripts are modified to compile F90 sources;

1638: fine...);
1639: - NOT is not correctly formatted in formateur.c:
1640: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1641: with a NOTZ function !
1642: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1645: - RPL/2 is tested with efence and valgrind;
1646: - configure.in script is modified;
1647: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1708: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1709: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1710: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1727: - SCLS is added;
1728: - DRWS now uses COLS to draw 2D graphics;
1729: - PPAR and SPAR are written. SPAR returns a list that contains the
1730: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1731: statistical variable, or "DISABLED" if its type is not one of the type of
1732: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1733: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1734: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1735: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1736: disabled. Arguments of EXTERNAL are case sensitive because the external
1737: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1738: of known external functions but add the new list to the last. { "all" }
1739: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1740: external names of the known functions;
1741: - mkrplso.in is modified.
1742: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1756: VISIT does not find a name in level 1;
1757: - configure.in script is modified to add a new test (--enable-debug
1758: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1759: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1760: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1761: 'MATRIX' { 2 2 3 } GETR;
1762: - LOGSCALE intrinsic is improved and now, it can be used as
1763: { "main" "auxiliary" X Y } LOGSCALE;
1764: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1765: same than AXES:
1766: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1767: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1768: { { -10 10 } "automatic" } SCALE.
1769: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1770: because it changes only the dimension of the screen. To have a logarithmic
1771: scale, you must use LOGSCALE intrinsic:
1772: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1773: screen on second scale;
1774: - { X X } autoscale and { Y Y } logscale are now invalid;
1775: - *D is added (depth multiplication, for 3D graphics);
1776: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1777: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1778: - a major bug is fixed in GETI instrinsic when it is used with a name
1779: that contains a matrix or a vector (bad upper bounds conditions in
1780: incrementation);
1781: - DISP intrinsic now uses the 33-th flag. When it is not set
1782: (default), a final carriage return is sent to the terminal;
1783: - AXES intrinsic only takes a list that can contains the keywork
1784: "main" or "auxiliary". Before this modification, this keyword was in
1785: the first stack level;
1786: - vim syntax file is upgraded;
1787: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1788: option;
1789: - LAST is now disabled in the main loop of INT intrinsic;
1790: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1791: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1792: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1793: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1794: in 0);
1795: - LAST is disabled in the main loop of DRAW intrinsic;
1796: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1797: evaluation of an equation, the system stack is returned corrupted to the
1798: sequencer;
1799: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1800: of a loop are not integer or real.
1801: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1804: add some tests in gestion_variables.c;
1805: - recherche_type() subroutine ad some other connex subroutines are improved.
1806: Now, some syntax errors about object are caught and do not perform sequencer
1807: hangup;
1808: - readline is upgraded (minor compilation bug with recent gcc);
1809: - Makefile.am's and configure.in scripts are improved.
1810: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1811: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1812: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1814: - recherche_type() is rewritten to be faster;
1815: - gsl is upgraded (release 1.3);
1816: - ncurses is upgraded and patched (release 5.3);
1817: - recherche_instruction_suivante() is fixed (string research with included
1818: '"') and rewritten to be faster;

1829: - a minor bug is fixed in evaluation subroutine;
1830: - vim syntax file is improved;
1831: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1832: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1833: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1834: is a quick and dirty workaround...);
1835: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1836: - rplconvert is improved.

1936: signal is an asynchonous "HALT" command;
1937: - SIGINT (CTRL+C) variables stack corruption is fixed;
1938: - IFERR seems to be fixed (in equation evaluation routine);

1946: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1947: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1948: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1949:
1950: Newton:[~/rpl/rpl] > time make install
1951: ...
1952: real 338m39.623s
1953: user 324m32.290s
