I have posted this on Stackoverflow as well but thought there might be someone here that could help

I have a button on an XPage that calls the function thisAction. The Page has the resource jsMain loaded and it contains the code below

function thisAction(msg:String){
    try{
    include ('jsSave.js')
    switch(msg){
    case "Save" :
        print("This action = " + msg);
        if (processAction()){
            print("processAction returned true");
            return true;
            break;
        }else{
            print("processAction returned false");
            return false;
            break;
        }
    default:
        print("In default msg is " + msg);
        return false;
        break;
    }
    }catch(e){
        print("thisAction Failed in jsMain " + e.toString())
    }
}

I have another js Script library called jsSave that has a function processAction. If I add the jsSave resource to my calling page all works well. However, for reasons that I wont go into I don't want to add the resource to my page but want to add it to my code in jsMain. The compiler wont accept the include statement though documentation I have found on line would suggest that it should be OK. I have found some examples where they modify the document header but I can't alter the source page. 

Any ideas?
