You must at the very least give the parameter a value. A null

pass null each time you are calling it yourself. If it is valid
depends on what the function does with it.
Well it will work, though I think it's not the best practice.
If I have an event handler that does "taskX", and I want to do taskX
directly without an event, I would code this as
function onSomeEvent(e:Event):void {
taskX();
}
and have a separate taskX() function to allow that to be called
directly. Then there's no ambiguity over whether a function is an event
handler or not. Generally speaking calling event handlers directly is to
be avoided.
