* contrib/rddads/rddads.h
* contrib/rddads/ads1.c
* contrib/rddads/adsfunc.c
* contrib/rddads/adsmgmnt.c
+ Added ACE version autodetection.
You can override with: -DADS_LIB_VERSION=700 (and similar)
(ADS_REQUIRE_VERSION still accepted for compatibility)
! Fixed a few lib version related problems.
! hMgmtHandle global renamed to ads_g_hMgmtHandle.
* Formatting.
* contrib/rddads/rddads.h
+ QUESTION: added about ADS_MAX_KEY_LENGTH redefinition.
Is it needed?
* source/compiler/hbmain.c
* Changed output device (hb_compOutStd() -> hb_compOutErr())
for following texts:
"Compiling..."
"No code generated"
"Lines x, Functions/Procedures x"
This is to replicate CA-Cl*pper behaviour a bit more.
* include/hbextern.ch
* common.mak
* source/rtl/Makefile
* source/rtl/maxrow.c
+ source/rtl/scrrow.c
* contrib/xhb/hbcompat.ch
+ Added hb_ScrMaxRow(), hb_ScrMaxCol()
These will return the screen dimensions regardless
of the size of an active window (when using CT
windows for example). Functionality is the same
as MaxRow(.T.) and MaxCol(.T.) previously.
! MaxRow()/MaxCol() extended parameters removed.
+ Added MaxRow(.T.)/MaxCol(.T.) conversions for
xhb lib (hbcompat.ch) in both directions.
; XBase++ doesn't have any extended parameters
for Max*() function. Flagship has two of them,
both of them doing something different. CAVO doesn't
have these functions at all.
* contrib/xhb/hbcompat.ch
! GTI_* macros updated to HB_GTI_*.
* source/vm/memvclip.c
% Minor opt in __QQPUB().
* source/vm/extend.c
* 0 -> NULL
