Multiply Word By Byte

[Scorpion Illuminati]

I have a byte variable called multiplier in ram. I want to multiply 100 by it's value and add the result to another ram value of type wordword called score. What would be the simplest approach to doing it? Any assistance in this matter would be greatly appreciated.

Sincerely,

Scorpion Illuminati

I suspect you mean longword instead of wordword? Anyway ..

	move.b	(multiplier),d0
	mulu.w	#100,d0
	add.l	d0,(score)

.. and don't forget to set d0 to zero if you need to ( using moveq #0,d0 ).
