Instead of using
cumbersome to type, you can create a local variable and store the path in the variable, which you
can then reuse in your code, as shown in the following ActionScript:
var shortcut = this._parent._parent.name_txt;
shortcut.text = "Hank";
shortcut.autoSize = true;

Example
The following example sets the
instructs
someOther_mc
with (someOther_mc) {
_x = 50;
_y = 100;
gotoAndStop(3);
}
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. In

the following example, the built-in

function polar(r:Number):Void {
var a:Number, x:Number, y:Number;
with (Math) {
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.
area = 28.2743338823081
x = -3
y = 3
