Simple help: How to initialize x scale and y scale into precentages

Hi, it’s me again. This is probably a simple help request: How can I convert the current scale of the instance to 100% so I can easily “visualize” and manage the instance when I modify its scale? Here’s the actionscript, it works, but I just want the temp._xscale and temp._yscale to be in precentages, not real numbers.

USflag.onMouseDown = function ()
{
    var temp = USflag;
    
    onEnterFrame = function ()
    {
        //the two variable's value is currently between 20-30, I want it to be just 100%.
        temp._xscale = temp._yscale *= .9;
        trace (temp._xscale);
        if(temp._xscale < 5)
        {
            delete onEnterFrame;
        }
    }
}

One last thing, what’s the tag you have to put that is designed for boxing actionscripts? I’m suing [ code ][ /code ]
