Different amount of variables in same function

[Kent]

I would like to create a function that is variable in the number of variables it processes.

Example
function myFunction(myVariableVar){
// Loop through the myVariableVar list and do the function
}

So when the function is used on different pages like this
3 variables: myFunction(var1,varb,varc);
or more variables: myFunction(var1,varb,varc,var4,vard,var7,var5,var9 );

bearing in mind that the vars used will be valid elementIDs or elementNames
I would like help to start the function ie, the "loop command" and i will add the function. If this is not too hard for you script gurus.

Thankyou

This is a an Array method that runs the same function
on each of its members, and returns an array of the results.
I include an example function to test- you can adapt it for your purpose.

**************************/

Array.prototype.forAll= function(fun,args){
    var L= this.length, A= [], tem;
    for(var i= 0; i< L; i++){
        try{
            if(args===true)tem= fun(this[i]);
            else tem= fun.apply(this[i],args);
        }
        catch(er){
            tem= null;
        }
        if(boo=== true && !tem) continue;
        A.push(tem);
    }
    return A;
}

// ************************** test function

var fun= function(){
    return ('\n'+i++) +'. '+this.tagName+
    '-  descendents: '+ this.getElementsByTagName('*').length;
}
function collect(hoo){
    var collection= [], who,i=0;
    var L = hoo.length;
    if (hoo.length) while(i< L) collection.push(hoo[i++]);
    else if (typeof hoo == "object"){
        for (var o in hoo) if(hoo.hasOwnProperty(o)) collection.push(hoo[o]);
    }
    return collection;
}
var A=document.body.getElementsByTagName('*');
A=collect(A);
var i=1;

// ************************** And the function command:

A= A.forAll(fun)
alert(A.slice(0,25));
