It is possible, just instead for or while you need to use Timers.

import flash.utils.Timer;
import flash.events.TimerEvent;

var tick : uint = 0;

var timer:Timer = new Timer ( 10, loopNum );
timer.addEventListener ( TimerEvent.TIMER, handleLoopTick );
timer.start ();

function handleLoopTick ( e : TimerEvent )
{
    trace ( this, ( tick / loopNum ) * 100 ); // outputs percentage for example

    tick++; // increasing the tick
}
