* harbour/include/hbapi.h
* harbour/source/vm/arrays.c
* added hb_arraySelfParams()
* harbour/include/hbapierr.h
* harbour/source/rtl/errorapi.c
+ added HB_ERR_ARGS_SELFPARAMS for automatic setting as argument list
array with self item and passed parameters
* harbour/source/rtl/copyfile.c
* harbour/source/rtl/str.c
* harbour/source/rtl/strtran.c
* harbour/source/rtl/strzero.c
* harbour/source/rtl/substr.c
* harbour/source/vm/arrayshb.c
* harbour/source/vm/classes.c
* harbour/source/vm/evalhb.c
* harbour/source/vm/memvars.c
* harbour/source/vm/runner.c
* use HB_ERR_ARGS_BASEPARAMS in generated RT messages
* harbour/source/rtl/fstemp.c
* formatting
* harbour/source/vm/hvm.c
! added some missing operator overloading
! fixed some error messages to be Clipper compatible
! fixed FOR loop for nonnumerical value and STEP, f.e.:
FOR d := date() TO date() + 10 step 2
? d
NEXT
* added disabled code to support reverted FOR condition
like in Clipper. See below.
* harbour/source/compiler/harbour.y
* added disabled code to generate reverted FOR condition
like in Clipper. I cannot uncomment it because it will break
backward binary compatibility so I'll do that when some modification
will force PCODE version updating.
Enabling this code clean the following errors reported by hbtest:
! 2907 MAIN_MISC(200) TFORNEXT( NIL, NIL, NIL )
Result: "E BASE 1074 Argument error <= A:2:U:NIL;U:NIL F:S"
Expected: "E BASE 1075 Argument error > A:2:U:NIL;U:NIL F:S"
! 2919 MAIN_MISC(212) TFORNEXT( NIL, NIL, NIL )
Result: "E BASE 1074 Argument error <= A:2:U:NIL;U:NIL F:S"
Expected: "E BASE 1075 Argument error > A:2:U:NIL;U:NIL F:S"
