* harbour/source/rdd/usrrdd/usrrdd.c
+ added functions to set WorkArea flags USRRDD_SETBOF, USRRDD_SETEOF,
USRRDD_SETFOUND, USRRDD_SETTOP, USRRDD_SETBOTTOM
* harbour/include/hbapierr.h
+ added HB_ERR_ARGS_BASEPARAMS
* harbour/source/rtl/errorapi.c
! check if ARGS passed to __ERRRT_BASE() and __ERRRT_SBASE() are
valid to avoid possible GPF
* replaced old hack with passing ARGS in array for some chosen errors
by HB_ERR_ARGS_BASEPARAMS in hb_errRT_BASE and hb_errRT_BASE_SubstR
- it was impossible to generate Clipper compatible error message
* harbour/source/rtl/do.c
* use HB_ERR_ARGS_BASEPARAMS
* harbour/source/rtl/tobject.prg
* assign SELF to ARGS of error object when EG_NO[VAR]METHOD RT error
is generated - Clipper compatible.
* harbour/source/vm/classes.c
* added __msgNoMethod which is returned to hb_vmSend when object does
not support requested message. This handler can display previous
Harbour error message though now it's disabled and Clipper compatible
error message is generated. I leave the decision to Harbour users
which version of error message should be used.
* changed __msgClsSel to return variable size array with only valid items
If some code needs fixed size array then it will have to be updated
* harbour/source/vm/hvm.c
* generate Clipper compatible error messages for EG_NO[VAR]METHOD
and EG_NOFUNC. Please do not change it. If you want previous Harbour
error messages for EG_NO[VAR]METHOD then please change __msgNoMethod
in classy.c
* harbour/source/vm/arrays.c
* minor modification
