assign each a class (say MC1, MC2 and MC3):

var mc2:MC2;

var mc1:MC1=new MC1();

addChild(mc1);

mc1.addEventListener(Event.ENTER_FRAME,f1);

function f1(e:Event){

if(mc1.currentFrame==mc1.totalFrames){

mc1.removeEventListener(Event.ENTER_FRAME,f1);

removeChild(mc1);

mc1=null;

mc2=new MC2();

addChild(mc2);

mc2.addEventListener(Event.ENTER_FRAME,f2);

}

}

function f2(e:Event){

if(mc2.currentFrame==mc2.totalFrames){

mc2.removeEventListener(Event.ENTER_FRAME,f2)

removeChild(mc2);

mc2=null;

var mc3:MC3=new MC3();

addChild(mc3);

}
