how do I do that?

BOOL Range_Within_100(int value, int another_value)
	{

	return (abs(another_value-value) <= 100);

	}

  

BOOL Range_Within_100(int value, int another_value)
	{

	_asm
		{

		// do subtraction: another_value - value

		mov ecx, another_value
		sub ecx, value

		// absolute value

		mov	edx, ecx
		sar edx, 15
		xor ecx, edx
		sub ecx, edx

		// assume it's not within range

		sub eax, eax

		// we were correct

		cmp ecx, 100
		jg done

		// no we weren't change it to 1 (withing range)

		inc eax
	done:

		// return value in EAX

		}

	}
