How do you call a parent class'es method?

[AuxV3i]

'->title says it all

how!!?!!?
EDIT-or get a variable in a parent class(no i dont want to declare it with the child), i want to be able to on-demand call it, because it changes.

as in, here is my main code
_______________________________

import MyClass;
var WantThis:int = 7
var myObject:MovieClip
function getWantThis():int{
return WantThis
}

myObject = new MyClass()
addChild(myObject)

_________________________
now this is part of the code of "MyClass"
_________________________

package*bla bla bla...
trace("the value of WantThis in my parent class is "+********************)

_________________________


'->what do i put here so that i can always have an updated value of the variable WantThis, on demand whenever i want to, because it would change!! do i access the variable? or call that method getWantThis??? how do i do either of those!!

thanks for any help!!
