need some reference help on col. new to flash/as

[acridcola]

I'm curious what "col" is and which is better between these two sets of code. I can't find which version of actionscript "col" is from.


Codes attached to a mc, an empty box outline graphic over a text field.

this.test_mc.co l = new Color(this.test _mc.text);
this.test_mc.se tRGB(frontcolor );

this.test_mc.on RollOver = function ():Void {
this.col.setRGB (backcolor);
}

VS

this.test_mc.on RollOver = function():Void {
this.text.textC olor = backcolor;
}

Thanks
