* harbour/include/hbapi.h
* harbour/source/vm/itemapi.c
* harbour/source/vm/garbage.c
+ added extended item references - it's universal reference which
can be used by HVM for many different things without introducing
new item types
* harbour/include/hbexprb.c
* respect -ks compiler also with <op>=, --, ++ operators
* harbour/include/hbvm.h
* harbour/source/vm/hvm.c
* harbour/source/vm/classes.c
+ added extended references for SETGET methods used as object
item references
* use extended references to respect overloaded [] operator in
object item references
+ added support for passing indexes to string item characters
( @cValue[n] ) by reference using extended references - extension
enabled by -ks compiler switch and //flags:s RT switch.
+ added hb_vmPushItemRef()
* harbour/source/rdd/dbf1.c
* harbour/source/rdd/usrrdd/usrrdd.c
* use hb_vmPushItemRef()
* harbour/contrib/xhb/xhbcomp.prg
* harbour/contrib/xhb/xhbmsgs.c
* overload +, -, *, %, ^, ++, -- in string and numeric scalar
classes to emulated xHarbour behavior when 1 byte string is
used as numeric value.
Note: <nun> + <char1> in XHB lib gives numeric value when in
xHarbour character. But because <nun> <anyOtherOper> <char1>
in xHarbour gives numeric value then I guess that it's
xHarbour bug and I should not replicate it, f.e.:
proc main()
? 1+"A", 131-"A", 33 * 2, 132 / chr(2), 133 % "C"
return
* overload +, - in hash scalar class to emulated xHarbour behavior
for <hash> + <hash> and <hash> - <hash>
Seems that now we can remove HB_COMPAT_XHB flag from HVM and keep
Harbour compatibility only with -ks compile time switch and XHB
library. Please make some tests with Harbour compiled without
HB_COMPAT_XHB and xHarbour code using REQUEST XHB_LIB. It's possible
that I missed sth but some basic test shows that our emulation is
better then original and addresses places where xHarbour does not
work at all or gives strange results, f.e.:
#ifndef __XHARBOUR__
request XHB_LIB
#endif
proc main()
local h:={"ABC"=>123.45}
? h:abc
h:abc+=1000 ; ? h:abc
h["ABC"]+=1000; ? h:abc
p(@h:abc) ; ? h:abc
p(@h["ABC"]) ; ? h:abc
return
proc p(x)
x+=1000
return
or:
#ifndef __XHARBOUR__
request XHB_LIB
#endif
#include "hbclass.ch"
proc main()
local o:=myClass():new()
o:setget:="ABC"; ? o:setget
o:setget[2]:=42; ? o:setget
o:setget[2]+=42; ? o:setget
? o:setget[2]+=42; ? o:setget
?
o:var:="ABC"; ? o:var
o:var[2]:=42; ? o:var
o:var[2]+=42; ? o:var
? o:var[2]+=42; ? o:var
return
CREATE CLASS myClass
VAR var
METHOD setget SETGET
END CLASS
METHOD setget( xNewVal ) CLASS myClass
IF pcount() > 0
::var := xNewVal
ENDIF
RETURN ::var

* changed second parameter in RELTEXT() method to PHB_ITEM
Now RELTEXT() works like FILTERTEXT() and the size of
expression is not limited. It's a modification I wanted
to make for a long time and I think that now is a good
moment to make it together with HB_FT_* modifications
- rmoved not longer necessary HARBOUR_MAX_RDD_RELTEXT_LENGTH
* harbour/source/rtl/gttrm/gttrm.c
* small cleanup
RDD for Advantage Database Server
Alexander Kresin <alex@belacy.belgorod.su>
For using this RDD you need to have:
ace32.dll ( Advantage Client Engine ),
AXCWS32.DLL ( communication layer for remote server ) or
ADSLOC32.DLL ( local server )
You need also to create ace32.lib with the help of implib.exe:
implib ace32.lib ace32.dll
Then build rddads.lib using make_b32.bat or make_vc.bat.
For building executables don't forget to include the ace32.lib and
rddads.lib to the make file or link script.
You need also to include to your prg file following lines:
REQUEST _ADS
rddRegister( "ADS", 1 )
rddsetdefault( "ADS" )
By default RDD is tuned for remote server and cdx indexes. To
change this you may use commands, defined in ads.ch:
SET SERVER LOCAL
SET FILETYPE TO NTX ( SET FILETYPE TO ADT )
or functions AdsSetServerType(), AdsSetFileType().
