Question

I have some code in a frame. It’s basically

this.addEventListener(Event.ENTER_FRAME, handleUpdate);
function handleUpdate(e:Event):void
{...}

I want the code to be executed only when on that frame. But the handleUpdate function keeps getting called even when I’m out of that frame.

The timeline is stopped on this frame, and I want the handleUpdate to run continuously until the timeline moves off the frame.

If you’re set on having the code for this on the frame in question, then you could do this:

        var tmpCurFrame:int = currentFrame; //store the current frame
        this.addEventListener(Event.ENTER_FRAME, handleUpdate)

        function handleUpdate(e:Event):void {
            if (tmpCurFrame != currentFrame) { //if the frame has changed, stop the frame handler
                this.removeEventListener(Event.ENTER_FRAME, handleUpdate);
                return;
            }
            //do your code
        }

        handleUpdate(null);

As an aside, it’s much cleaner to have a document class and other class files that manage this sort of thing instead of using frame scripts. But if you all you’re looking for is a quick and dirty tweak to your existing code, this should do the trick.
