The following code snippet shows how to write the preceding code without using a
statement.
someOther_mc._x = 50;
someOther_mc._y = 100;
someOther_mc.gotoAndStop(3);
The statement is useful for accessing multiple items in a scope chain list simultaneously.

a = PI * pow(r, 2);
x = r * cos(PI);
y = r * sin(PI / 2);
}
trace("area = " + a);
trace("x = " + x);
trace("y = " + y);
} polar(3);
The following result is displayed in the Output panel.
