You can reach command line arguments using system.args. And i use the solution below to parse arguments into an object, so i can get which one i want by name.

var system = require('system');

var args = {};
system.args.map(function(x){return x.split("=")})
    .map(function(y){args[y[0]]=y[1]});

now you don't need to know the index of the argument. use it like args.whatever

Note: you should use named arguments like file.js x=1 y=2 to use this solution.
