How to rotate MC continuously and stop it?

How can I rotate an MC continuously and stop it using a button?


MC.rotation += 1;

I tried using the code above but it won’t rotate it continuously.
Then I tried searching the web,what I get is :


MC.addEventListener(Event.ENTER_FRAME, rotate);

yes,it will rotate my MC continuously but I don’t know what sort of condition
if I want : click will rotate it continuously and then stop it by clicking it again or using a stop button.

I’m not sure if I want to use conditional(not sure about the code too) or are there any way that more efficient than the ENTER_FRAME ?:block:

thanks.
