Returning values from a function

Use the return action to return values from functions. The return action stops the function and replaces it with the value of the return action. If Flash doesn't encounter a return action before the end of a function, an empty string is returned. For example, the following function returns the square of the parameter x:

function sqr(x) {
	return x * x;
}

Some functions perform a series of tasks without returning a value. For example, the following function initializes a series of global variables:

function initialize() {
	boat_x = _root.boat._x;
	boat_y = _root.boat._y;
	car_x = _root.car._x;
	car_y = _root.car._y;
}
