IF statement in assembly

I'm wondering, Does assembler support if staments? (like a C program) Tried something very simple:

org 0h
sjmp BEGIN

org 50h
BEGIN:
	IF R0 == #45
		MOV A, #54
		CPL A
	ELSE
		MOV A, #45
		CPL A
	ENDIF
END

After building and enter debug mode I found this code seems to be a #ifdef like statement instead of a C like if-then-else statement. Did I do something wrong or the assembler does no support if statement?

IF R0 ==
can not be done ITS CODE, you can not do an not an IF on a register

cjne AR0,#45,not45
mov a,#-54
sjmp done
not45: mov a,#-45
