Script Help

I am a college student at Furman University and I am doing a project for Computer Science in which I am building informative web pages for students. I really want to use the javascript distance calculator between cities that is offered on this site but Greenville, SC is not offered. I figured out how to put Greenville on the list but I cannot figure out how to read that code that tells where the city is located because it is in “al” string is there anyway to convert it so Greenville can be added to the list. Heres a sample from the actual script:

<script language=”JavaScript”>

var l=0;
var r=0;
var tc=””;
var al=” abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ”
+”123456789″;
var ns=”0123456789″;

function iA(){
this.length=iA.arguments.length;
for (var i=0;i<this.length;i++){
this[i]=iA.arguments[i];
}
}
/* 5829 byte database of distances uses position in the
string “al” to substitute for the numerics, saving a bit
