Using a for loop to streamline code?

I have some AS2 code that has a lot of duplication to control various buttons and MovieClips and was wondering if it's possible to streamline this code using a 'for' loop, like I would when attaching MovieClips dynamically.

Here's the code as it's currently written:

Code:

---


//----------- INIT VARS -------------------------

var color01:String = "0xE24C9B";
var color02:String = "0x009BDB";
var color03:String = "0x50B848";
var color04:String = "0xF58220";

var base01:MovieClip = timer01_mc.timerBase_mc;
var base02:MovieClip = timer02_mc.timerBase_mc;
var base03:MovieClip = timer03_mc.timerBase_mc;
var base04:MovieClip = timer04_mc.timerBase_mc;

var btn01:Button = timer01_mc.rollBtn_btn;
var btn02:Button = timer02_mc.rollBtn_btn;
var btn03:Button = timer03_mc.rollBtn_btn;
var btn04:Button = timer04_mc.rollBtn_btn;

var bar01:MovieClip = timer01_mc.timerBar_mc;
var bar02:MovieClip = timer02_mc.timerBar_mc;
var bar03:MovieClip = timer03_mc.timerBar_mc;
var bar04:MovieClip = timer04_mc.timerBar_mc;

var url01:String = "http://www.url01.com";
var url02:String = "http://www.url02.com";
var url03:String = "http://www.url03.com";
var url04:String = "http://www.url04.com";

//-------------- BUTTON CONTROL -------------------------

btn01.onRollOver = function(){ baseCol01 = new Color(base01); baseCol01.setRGB(color01);
};
btn01.onRollOut = function(){ baseCol01 = new Color(base01); baseCol01.setRGB(0xCCCCCC);
};
btn01.onRelease = function(){ getURL(url01, "_blank");
};

btn02.onRollOver = function(){ baseCol02 = new Color(base02); baseCol02.setRGB(color02);
};
btn02.onRollOut = function(){ baseCol02 = new Color(base02); baseCol02.setRGB(0xCCCCCC);
};
btn02.onRelease = function(){ getURL(url02, "_blank");
};

btn03.onRollOver = function(){ baseCol03 = new Color(base03); baseCol03.setRGB(color03);
};
btn03.onRollOut = function(){ baseCol03 = new Color(base03); baseCol03.setRGB(0xCCCCCC);
};
btn03.onRelease = function(){ getURL(url03, "_blank");
};

btn04.onRollOver = function(){ baseCol04 = new Color(base04); baseCol04.setRGB(color04);
};
btn04.onRollOut = function(){ baseCol04 = new Color(base04); baseCol04.setRGB(0xCCCCCC);
};
btn04.onRelease = function(){ getURL(url04, "_blank");
};

Can anyone show me how to construct the correct type of 'for' loop to streamline this code?

You can reference objects as shown below. You can have the buttons share functions:

for(var i=1;i<=4;i++){
holderClip["btn0" + i].buttNo = i;
holderClip["btn0" + i].onRollOver = overButton;
holderClip["btn0" + i].onRollOver = offButton;
holderClip["btn0" + i].onRollOver = pressButton;
}

Whatever button calls the function can be referenced by "this":

function pressButton(){
trace("button " + this.buttNo + " was pressed");
}

When btn04 is pressed it will trace "button 4 was pressed".
