* harbour/source/rtl/errorapi.c
+ added protection against possible GPF when some assign methods
were called without parameters
* harbour/source/rdd/workarea.c
* initialize uiFalgs also when DBS_FLAGS is not set
* harbour/contrib/bmdbfcdx/bmdbfcdx1.c
* fixed hb_cdxSkipFilter() declaration - it should be 'static' function
* harbour/source/pp/ppcore.c
* harbour/source/compiler/ppcomp.c
+ added support for changing all -k? switches by #pragma, f.e.;
#pragma -ks+
#pragma -kM-
#pragma -kx1
#pragma -kJ0
* harbour/source/compiler/hbusage.c
* changed -ks description
* harbour/include/hbexpra.c
* harbour/include/hbexprb.c
* do not generate error message for negative indexes and
[] operators are used for simple types when -ks option
is used
* harbour/include/hbvmpub.h
* harbour/include/hbapi.h
* harbour/source/vm/hvm.c
* harbour/source/vm/extend.c
* harbour/source/vm/itemapi.c
* harbour/source/vm/memvars.c
+ added HB_IT_DEFAULT flags - it allows to check if item was changed
* harbour/source/vm/memvars.c
* harbour/include/hbvm.h
! fixed HB_IT_MEMOFLAG updating to be Clipper compatible. Here we are
not Clipper compatible in one place: in clodeblock local parameters
with memo values are marked as MEMO but if you leave function where
codeblock were created then Clipper during detaching removes MEMO
flag. In Harbour memo flag is kept.
* harbour/include/hbvm.h
* harbour/source/vm/classes.c
* harbour/source/vm/hvm.c
% improved speed of extended references used for SETGET methods
and overloaded [] operators
* harbour/include/hbapi.h
* harbour/include/hbsetup.ch
* harbour/source/compiler/hbcomp.c
* harbour/source/vm/hvm.c
* harbour/source/vm/macro.c
* harbour/source/vm/cmdarg.c
* removed HB_COMPAT_XHB flags - only one HB_COMPAT_XHB still exist
in HVM in hashes.c - it will be removed soon.
* harbour/source/common/hbverdsp.c
* removed information about xHarbour compatibility mode - it's not
longer used. We are emulating xHarbour behavior using external
XHB library and standard compiler/HVM features
* harbour/contrib/xhb/xhb.ch
* harbour/contrib/xhb/xhbfunc.c
* harbour/source/vm/arrayshb.c
* moved XHB_AINS(), XHB_ADEL() from XHB lib to HVM as HB_AINS(), HB_ADEL()
* harbour/contrib/xhb/xhb.ch
+ added #pragma -ks+
+ added transaltion for hb_enumindex( <enumvar> )
+ harbour/contrib/xhb/xhbenum.c
+ added emulation for HB_EUMMINDEX()
* harbour/contrib/xhb/xhbfunc.c
* do not add INET*() function wrappers for DOS builds or when
HB_NO_DEFAULT_INET macro is set
* harbour/contrib/xhb/xhbmsgs.c
* added comment
* harbour/contrib/Makefile
+ added TIP and XHB
* harbour/make_rpm.sh
* harbour/harbour.spec
* removed HB_COMPAT_XHB, --with tip, --with xhb
they are not longer necessary

|
|
*
|
|
* a:b( COUNT() ):c += 1
|
|
*
|
|
* will be handled as:
|
|
*
|
|
* a:b( COUNT() ):c := a:b( COUNT() ):c + 1
|
|
*
|
|
* in strict Clipper compatibility mode
|
|
* (HB_SUPPORT_HARBOUR is not set: -kc compiler switch ) and
|
|
*
|
|
* temp := a:b( COUNT() ), temp:c += 1
|
|
*
|
|
* in non-strict mode (-kh).
|
|
* In practice in Clipper it will call COUNT() function two times: the
|
|
* first time before addition and the second one after addition - in Harbour,
|
|
* COUNT() function will be called only once, before addition.
|
|
* The Harbour (non-strict) method is:
|
|
* 1) faster
|
|
* 2) it guarantees that the same instance variable of the same object will
|

* be changed
