In some 44: circumstances, this function can return a spurious error; 45: - new NATIVE*(*) data format is added. By default, native*(*) is used 46: to write data without precision loss. It can also be used to write 47: complex objects like expressions, lists or tables; 48: - major bug is fixed in formateur(). When INT64_MIN was pushed into stack, 49: internal value was good but RPL/2 was not able to correctly display 50: this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented 51: in integer.

When a global 360: variable was created and when a local variable existed with the same name, 361: computed address of global variable was wrong; 362: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3 363: is forced in front of all libraries. 364: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2) 365: - BACKTRACE intrinsic is added; 366: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs 367: when this structure is included in IFERR/THEN/END structure and when an error is 368: caught; 369: - major bug is fixed in analyse() subroutine. When evaluation() returned error 370: in a compiled program, analyse() caught this error twice and randomly aborted 371: with a segmentation error; 372: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces; 373: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop 374: signals; 375: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty 376: matrix. 377: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2) 378: - minor bug is fixed in evaluation() subroutine.

Warning: [[]] SIZE 1528: returns { 1 0 } and it is not a bug, because a null matrix contains _one_ 1529: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 }; 1530: - EXTERNAL intrinsic is added. Warning: by default, extern functions are 1531: disabled. Arguments of EXTERNAL are case sensitive because the external 1532: interface is written in C. { ext_sinus } EXTERNAL does not replace the list 1533: of known external functions but add the new list to the last. { "all" } 1534: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all 1535: external names of the known functions; 1536: - mkrplso.in is modified. 1537: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2) 1538: - vim syntax file is upgraded; 1539: - a minor mistake is fixed in recherche_instruction_suivante(); 1540: - some minor memory leaks are fixed in recherche_type() function.

It only occurs when 1551: VISIT does not find a name in level 1; 1552: - configure.in script is modified to add a new test (--enable-debug 1553: flag). Configured with this fleg, RPL/2 will be built with electric-fences; 1554: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions 1555: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or 1556: 'MATRIX' { 2 2 3 } GETR; 1557: - LOGSCALE intrinsic is improved and now, it can be used as 1558: { "main" "auxiliary" X Y } LOGSCALE; 1559: - SCALE intrinsic is used to fix the limits of a graphic.

To have a logarithmic 1566: scale, you must use LOGSCALE intrinsic: 1567: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log 1568: screen on second scale; 1569: - { X X } autoscale and { Y Y } logscale are now invalid; 1570: - *D is added (depth multiplication, for 3D graphics); 1571: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y 1572: and Z axes).
