361: subroutines;
362: - fix major memory access violation in evaluation subroutine. Only occurs
363: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;

379: - ALARM is fixed by filling isdst field;
380: - catch ECONNRESET in write intrinsic to return an execution error instead of
381: system one;
382: - fix a typo in HELP intrinsic;
383: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2;

386: - ncurses is upgraded;
387: - regression introduced by 4.0.19 is fixed in signal management.
388: Interruption1() could be called from itself and raises bus error (on sparc) or
389: segmentation fault;
390: - sqlite is upgraded to 3.7.4;
391: - OpenSSL is upgraded to 1.0.0c;
392: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);

394: - gnuplot is upgraded to 4.4.2 due to major bugs.
395: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
396: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
397: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
398: corruption. As internal memory management have been improved, a best fit
399: allocator like ptmalloc3 is not required anymore;
400: - gnuplot is upgraded to 4.4.1;
401: - deadlock is fixed in signal handlers: same mutex was used in standard
402: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
403: and signal handlers. A new signal handler specific mutex is added;
404: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
405: that has to be evaluated by ->NUM;
406: - rplfile build process is modify to be sure that rplfile is not modified
407: after rpl build stage (to be sure that rplfile checksum is not modified after
408: rpl compilation);
409: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
410: modified to remove yacc code and renamed;

412: ABORT now works on eComStation;
413: - sqlite is upgraded to 3.7.2;
414: - bug is fixed in software interrupts. When both process have different PID,
415: parent process was not interrupted if it is not group master process. To fix
416: this bug, SIGINJECT signal is not sent by child process but by control thread
417: in parent process;
418: - minor bug is fixed in data injection (POKE) that does not work as expected
419: when child process is protected by NRPROC.
420: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
421: - --enable-sysv-sems is added to configure script to use SystemV semaphores
422: functions instead of POSIX functions. This function is disabled or forced on
423: systems that does not provide correct POSIX or SysV semaphores subsystem;
424: - a dirty but not quick patch is written to workaround broken siginfo
425: structures. This patch has been successfully tested. It uses a segment of
426: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
427: (Unix PID);
428: - some OpenBSD's hacks are added;
429: - broken siginfo->si_pid field is now checked by configure script;
430: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
431: - random generator is cloned by SPAWN;

438: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
439: - TOKENIZE is now able to convert escape sequences;
440: - ATPOKE and CLRATPOKE new intrinsics are added;
441: - --enable-full-static configure flag is added. With this flag, mysql and
442: postgresql libraries are statically linked in rpl executable;
443: - units Makefile is modified to avoid readline and ncurses usages;
444: - sqlite is upgraded to 3.7.0.1;
445: - units is upgraded to 1.88;
446: - another major bug is fixed in the same variable creation subroutine.
447: Level 0 and 1 variables adresses were swapped when a global variable masked
448: a name of RPL/2 routine;
449: - major bug is fixed in global variable creation subroutine. When a global
450: variable was created and when a local variable existed with the same name,
451: computed address of global variable was wrong;
452: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
453: is forced in front of all libraries.
454: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
455: - BACKTRACE intrinsic is added;
456: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
457: when this structure is included in IFERR/THEN/END structure and when an error is
458: caught;
459: - major bug is fixed in analyse() subroutine. When evaluation() returned error
460: in a compiled program, analyse() caught this error twice and randomly aborted
461: with a segmentation error;
462: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
463: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
464: signals;
465: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
466: matrix.
467: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

485: format in FCH (file descriptor) and SCK (socket descriptor);
486: - debug routines are improved;
487: - PROCID is added;
488: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
489: and to not use swap;
490: - major bug is fixed in sql support. SQL connections were closed in all chield
491: process;
492: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
493: discovered in Solaris thread safe allocators (libmalloc and libumem) that
494: are first fit class allocators. Solaris libmtmalloc works better and is
495: a best fit class allocator but its performance is poor than ptmalloc3
496: performance;
497: - major bug is fixed in ROW+ intrinsic (new row was not added where it
498: should);
499: - minor bugs are fixed in interruptions.c (semaphores values when error is
500: caught);
501: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
502: created by SPAWN;
503: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
504: ATEXIT. If it receives SIGFABORT, it does not;
505: - ONEXIT is renamed in ATEXIT;
506: - ONEXIT new intrinsic is added.

508: - major bug is fixed in static and shared variables initialization subroutine.
509: This bug only occurs when RPL/2 tries to create a shared or static variable
510: from an expression;
511: - major bug is fixed in copie_etat_processus(). A field that contains
512: information about shared variable was not copied to new processus structure;
513: - some little memory leaks are fixed in evaluation(), recherche_type() and
514: sequenceur(). They only occured when syntax error were caught;
515: - IMPLICIT causes execution error instead system error;
516: - Hurd support is improved but currently broken because Hurd does not support
517: SIG_INFO. Work in progress;
518: - OpenBSD specific support is removed from sources;
519: - support for Mac OS X and Windows/Cygwin is added.
520: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)
521: - implicit names can now be disabled by new IMPLICIT intrinsic:

558: rplc (RPL/2 compiler).
559: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
560: - in formatted file, string format returned a variable length string even if
561: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
562: a variable length string and 'CHARACTER*(n)' a fixed length string;
563: - keyed access files support is added. Currently, only formatted files are
564: supported;
565: - direct access files support is added. Currenlty, these files can only be used
566: in formatted mode;
567: - virtual variables are now writte in UTF-8 and all special characters
568: in string are escaped;
569: - all formatted files are now converted into UTF-8;
570: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
571: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
572: each execution (md5 and sha1 sums) to enhance security. If one of these tools
573: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
574: on a non recoverable system error;
575: - openssl and sqlite3 libraries are added;
576: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
577: variable indicates RPL/2 root directory. If it is not set, root path
578: is given by configure script (d_exec_path);
579: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
580: - configure.in and makefile.am's are modified to add Cygwin support. Interix

612: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
613: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
614: signals sent to main process were not caught because DAEMON did not replace
615: old pid by new one;
616: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
617: evaluation when an error is reported from a subroutine in another subroutine.
618: For example, error was not caught in following program when it is executed with
619: -p option :
620: TEST << iferr TEST2 then end >>
621: TEST2 << 0 inv >>
622: - major bug is fixed in variable management. Some local variables were
623: seen as global ones;
624: - major bug is fixed in rplcore. Rplcore entered in dead lock when
625: script file contains a multibyte character;
626: - IN intrinsic is added;
627: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
628: returned false ;
629: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
630: programs;
631: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
632: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
633: strings were never closed;
634: - some bugs have been fixed in file management;

636: - major bug is fixed in -A command line option (NULL character is missing);
637: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
638: made by blocks (1024 bytes). When an incomplete multibyte sequence is
639: encountered at end of block, subroutine aborts with an execution error;
640: - major bug is fixed in OPEN (TCP/IPv4 sockets).
641: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
642: - DISP now locks stdout;
643: - rpliconv is added to replace standard iconv provided by operating system.
644: Indeed, conversion between different encodages requires transliteration
645: that is not offered by some iconv utility;
646: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
647: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
648: not be found), SYSEVAL enters in a dead lock;
649: - fprintf is replaced by some functions that allow transliterations between
650: locales;
651: - '"' can now be used in strings ("\"");
652: - iconv is called with -c in preprocessor stage. It is done to write
653: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
654: - double free is fixed in liberation() (type SQL, only occurs when locale is
655: set);
656: - LOCALIZATION, UCASE and LCASE are added;

660: used in onLoading from shared library, USE was pushed on stack as algebraic
661: expression;
662: - libiconv is upgraded to 1.13.1;
663: - gnuplot is upgraded to 4.2.6;
664: - gsl is upgraded to 1.13.
665: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
666: - pipe() is overwritten by a macro to avoid a system error. Communication
667: between process are done with pipes and these pipes are managed by a
668: specific asynchrone thread. If a script try to create more threads than
669: management thread can destroy, you can quickly achieve maximum number of
670: opened files and pipe() shall return a system error. This macro tries to create
671: pipes. If pipe() function returns an error, macro waits and retries. If
672: number of retries is greater than a hardcoded value, macro returns an error;
673: - major bug (deadlock) is fixed in process and thread management. I hope
674: this bug shall be the last one;
675: - major bug is fixed in DET intrinsic (determinant was computed without LU
676: diagonalization);
677: - SWAPCNTXT is added;
678: - minor bug is fixed in Makefile.am (licences rule).
679: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
680: - some bugfixes are added in process management;
681: - all process management is rewritten to avoid usage of defunct process
682: or thread number;
683: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
684: was called before a pending interruption5 (SIGFSTOP), signal handler uses
685: a freed semaphore and corrupts heap;
686: - CLRERR is added to erase previous errors;
687: - ERRN and ERRM return exception message and number;
688: - major bug is fixed in interruptions.c. All signal are now bufferised
689: when semaphore_liste_threads is null to avoid deadlock. This bug only
690: occured when STOP was sent to a dying thread or process (when this thread or
691: process was running retrait_thread());
692: - matrix rank is computed before matrix inversion;
693: - file locks are added to stdin and stdout. stderr is not locked because
694: all messages written by signal handlers are sent to stderr;
695: - configure.in script is modified to test gcc version and avoid a bug in
696: gcc older than 4.4;

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

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

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

837: that all programs that worked with old SQL intrinsic can now work with
838: SQLQUERY. With all new programs, you can open a real connection to databases;
839: - NRPROC is added. This new intrinsic is used to catch error from child
840: process. Without NRPROC, any errors returned by child process cause
841: main process to abort;
842: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
843: starts a new process). There are no mutexes in RPL/2 because all spawned process
844: use specific context. Nevertheless, shared variables and associated mutexes
845: should be added;

1140: - external wrapper (rplplot) is written to force usage of gnuplot provided
1141: by RPL/2 if it is built during build process. If this build does not exist,
1142: it tries to launch regular gnuplot;
1143: - gnuplot is added to source tree to avoid some trouble between preinstalled
1144: gnuplot and release used by RPL/2. This addition to source tree is
1145: required by some incompatibility between gnuplot releases;

1520: (less parenthesis);
1521: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1522: on Debian distribution, but since cpp is in the default path, RPL/2 works
1523: fine...);
1524: - NOT is not correctly formatted in formateur.c:
1525: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1526: with a NOTZ function !
1527: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1528: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even
1529: if the main loop is in a program;
1530: - RPL/2 is tested with efence and valgrind;
1531: - configure.in script is modified;
1532: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1533: structure. I don't know why this code was compiled by gcc-3.3... Maybe
1534: another gcc bug...
1535: * Fri Jul 25 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7b (RPL/2)
1536: - EXIT is fixed. Now, it is possible to use EXIT in an expression when the
1537: main loop is in a program;

1568: 2: integer (number of column to be inserted)
1569: 1: column matrix to be inserted;
1570: - major bug was discovered in interface_gnuplot(). It only occurs when

1579: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1580: - SLICESCALE intrinsic is added. Its syntax is
1581: { "automatic" nb_of_levels }
1582: { "discrete" l1 l2 l3 ... }
1583: { "incremental" start incr }
1584: { "incremental" start incr end }
1585: { "automatic" } (default);
1586: - a minor bug (in last stack) is fixed in AXES intrinsic
1587: - flag 52 is used to automatically update graphics;
1588: - man pages are updated;
1589: - evaluation() is modified to perform evaluation of expressions that contain
1590: '=';
1591: - a minor bug is fixed in AXES intrinsic;
1592: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1593: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1594: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1595: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1596: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1612: - SCLS is added;
1613: - DRWS now uses COLS to draw 2D graphics;
1614: - PPAR and SPAR are written. SPAR returns a list that contains the
1615: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1616: statistical variable, or "DISABLED" if its type is not one of the type of
1617: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1618: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1619: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1620: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1621: disabled. Arguments of EXTERNAL are case sensitive because the external
1622: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1623: of known external functions but add the new list to the last. { "all" }
1624: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1625: external names of the known functions;
1626: - mkrplso.in is modified.
1627: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1628: - vim syntax file is upgraded;
1629: - a minor mistake is fixed in recherche_instruction_suivante();
1630: - some minor memory leaks are fixed in recherche_type() function. They only
1631: occurs when a syntax error is detected;

1633: - INCR and DECR are written (with integer or variable argument);
1634: - CSWP and RSWP are added and tested;
1635: - a minor bug is fixed in analyse.c;
1636: - DEBIAN/control is added to build debian package;
1637: - SCALE is fixed and improved ("automatic" keyword);
1638: - PUTC and PUTR new intrinsics are added.
1639: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1640: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1641: VISIT does not find a name in level 1;
1642: - configure.in script is modified to add a new test (--enable-debug
1643: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1644: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1645: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1646: 'MATRIX' { 2 2 3 } GETR;
1647: - LOGSCALE intrinsic is improved and now, it can be used as
1648: { "main" "auxiliary" X Y } LOGSCALE;
1649: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1650: same than AXES:
1651: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1652: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1653: { { -10 10 } "automatic" } SCALE.
1654: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1655: because it changes only the dimension of the screen. To have a logarithmic
1656: scale, you must use LOGSCALE intrinsic:
1657: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1658: screen on second scale;
1659: - { X X } autoscale and { Y Y } logscale are now invalid;
1660: - *D is added (depth multiplication, for 3D graphics);
1661: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1662: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1663: - a major bug is fixed in GETI instrinsic when it is used with a name
1664: that contains a matrix or a vector (bad upper bounds conditions in
1665: incrementation);
1666: - DISP intrinsic now uses the 33-th flag. When it is not set
1667: (default), a final carriage return is sent to the terminal;
1668: - AXES intrinsic only takes a list that can contains the keywork
1669: "main" or "auxiliary". Before this modification, this keyword was in
1670: the first stack level;
1671: - vim syntax file is upgraded;
1672: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1673: option;
1674: - LAST is now disabled in the main loop of INT intrinsic;
1675: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1676: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1677: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1678: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1679: in 0);
1680: - LAST is disabled in the main loop of DRAW intrinsic;
1681: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1682: evaluation of an equation, the system stack is returned corrupted to the
1683: sequencer;
1684: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1685: of a loop are not integer or real.
1686: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1687: - the compilation stage aborts with an error message when two definitions
1688: have the same name. To improve the compilation() subroutine, I have to
1689: add some tests in gestion_variables.c;
1690: - recherche_type() subroutine ad some other connex subroutines are improved.
1691: Now, some syntax errors about object are caught and do not perform sequencer
1692: hangup;

1694: - Makefile.am's and configure.in scripts are improved.
1695: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1696: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1697: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1698: the boxwidth, 1 by default);
1699: - recherche_type() is rewritten to be faster;
1700: - gsl is upgraded (release 1.3);
1701: - ncurses is upgraded and patched (release 5.3);
1702: - recherche_instruction_suivante() is fixed (string research with included
1703: '"') and rewritten to be faster;

1714: - a minor bug is fixed in evaluation subroutine;
1715: - vim syntax file is improved;
1716: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1717: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1718: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1719: is a quick and dirty workaround...);
1720: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1721: - rplconvert is improved.
1722: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1738: Now, an expression such as 'A+' returns an error when it is analyzed;
1739: - VISIT intrinsic is added;
1740: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1741: normal mode.

1829: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1830: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1831: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1832: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1833: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1834:
1835: Newton:[~/rpl/rpl] > time make install
1836: ...
1837: real 338m39.623s
1838: user 324m32.290s
1839: sys 10m47.380s
1840: Newton:[~/rpl/rpl] >
1841:
1842: I don't know if you will compile this language on old worstations, but
1843: it is usable ;-) ;
1844: - SYSEVAL is improved. An external program can be called without any shell.
1845: Thus, even if the sticky bit is set, RPL/2 can not give a shell root when
1846: a SYSEVAL command crashes;
