MACRO for alternative high level syntax in MASM 32 :boohoo:
MACRO is support additional flags of the processor (list see below).
@IF, @ELSEIF allows to use the additional commands for calculation of the conditions
Hope that in following version MASM 32 supports of these possibilities will be built-in .IF, .UNTIL, ...
-------------------------------------------------------------------------------------------------
Formats of alternative high level syntax [unessential parameters]:
@IF [<<command>>, ...], flags
...
[@ELSEIF [<<command>>, ...], flags] ; (see example below)
...
[@ELSE]
...
@ENDIF
Note: in << >> essential introduced only command, included comma (for example: <<mov EAX, 5>>)
- - - - - - - - - - - - - - - -
@REPEAT
...
[@BREAK]
[@BREAK [@IF] flags]
[@BREAK [.IF] flags]
...
@UNTIL [flags]
- - - - - - - - - - - - - - - -
@WHILE [flags]
...
[@BREAK]
[@BREAK [@IF] flags]
[@BREAK [.IF] flags]
...
@ENDW
-------------------------------------------------------------------------------------------------
List supported flag and their combination:
CARRY?, OVERFLOW?, PARITY?, SIGN?, ZERO?, EQUAL?, ABOVE?, ABOVE?||EQUAL?,
BELOW?, BELOW?||EQUAL?, GREATER?, GREATER?||EQUAL?, LESS?, LESS?||EQUAL?,
NOCARRY?, NOOVERFLOW?, NOPARITY?, NOSIGN?, NOZERO?, NOEQUAL?, NOABOVE?,
NOBELOW?, NOGREATER?, NOLESS?
--------------------------------------------------------------------------------------------------
FOR EXAMPLES:
include Alt_IF_en.mac
.data?
iVAR_1 dd ?
iVAR_2 dd ?
qVAR_3 dq ?
.code
- - - - - - - - - -
...
@IF <<or EDX, EDX>>, SIGN? ; register EDX < 0
...
@ELSEIF <<mov EAX, [iVAR_1]>>, <<cmp EAX, [iVAR_2]>>, GREATER?||EQUAL? ; iVAR_1 >= iVAR_2 (signed)
...
@ELSEIF FLD [qVAR_3], FICOMP [iVAR_2], FSTSW AX, SAHF, ABOVE?||EQUAL? ; qVAR_3 >= iVAR_2 (signed!)
... ; ATTENTION: at FPU compare use only UNSIGHED flags (ABOVE?, BELOW?)
... ; although FPU compare ALWAYS signed !!!
@ENDIF
; Note: in << >> essential introduced only command, included comma (for example: <<mov EAX, 5>>)
; - - - - - - - - - -
mov ECX, 15
@REPEAT
...
cmp EAX, -5
@BREAK @IF LESS? || EQUAL? ; early exit if EAX <= -5
...
cmp [iVAR_1], 10
@UNTILCXZ ABOVE?||EQUAL? ; exit from loop if [iVAR_1] >= 10 (unsigned) or ECX == 0

New version 2.0
Added MACRO for defined and undefined local labels:
call jmp @LABEL(имя_метки) possible use both before, and after DEFLABEL label_name[:]
DEFLABEL label_name[:] ; Define local label
@LABEL(label_name) ; Reference to local label
UNDEFLABEL label_name ; Close area define local label
after UNDEFLABEL possible define new label with same name!!!
All condition macro support of added command.
Remove limitation of nesting levels.
Fixed error in @WHILE.
