Passing movieClip names to different buttons/MCs

Question

I have 5 MCs on stage, acting as buttons (ChoiceA_mc to
ChoiceE_mc) - referred to in a loop (instead of individually naming
them). I have to disable all these MCs when one has been pressed
& reactivate them when the 'Next Question' button is pressed.
My script works but I think there is a much more efficient way of
doing it - so I don't have to repeat the 'for' loop 3 times.
I'd be grateful if anyone can show me a more efficient way of
doing this. Script is :
next_btn._alpha = 20;
next_btn.enabled = false;
// define content and actions for each answer button:
var choice:String;
for (var i = 65; i<=69; i++) {
choice = "choice"+String.fromCharCode(i)+"_mc";
this[choice].letter_txt.text = String.fromCharCode(i);
this[choice].id = String.fromCharCode(i);
// when this answer is chosen:
_root[choice].onRelease = function() {
for (i=65; i<=69; i++) {
var allButts:MovieClip =
this._parent["choice"+String.fromCharCode(i)+"_mc"];
allButts.enabled = false;
allButts.gotoAndStop("_up");
next_btn._alpha = 100;
next_btn.enabled = true;
next_btn.onRelease = function() {
this._alpha = 20;
this.enabled = false;
//show all 5 answer btns again:
for (i=65; i<=69; i++) {
allButts =
this._parent["choice"+String.fromCharCode(i)+"_mc"];
allButts.enabled = true;
};

Answer 1

you can do something like that:
public someClass {
someOtherClass obj;
public someclass (someOtherClass object) {
this.obj = object;
public void someMethod () {
if (condition) { obj.someOtherMethod();  }
public someOtherClass {
//constructor here
public void someOtherMethod () { //do Stuff }
like this you could pass values between your classes A, B and C
