Global Variables vs. File objects

[HawkArps]

I am trying to create a way to count the number of symbols in a Watchlist, and save that number somewhere where a different EFS can access it. I decide to use a file object that adds an element for every symbol in the Watchlist and then reads the length of that file to determine the number of elements counted. Later I will try and acces that number from a charting study. I don't know if this is the best approach, but I have not figured out how to have one study create/manipulate variables that a separate EFS can read. (I originally thought QLink may offer a solution, but importing calculations from an Excel doesn't seem to be possible either). I created the following code to count the number of symbols in a Watchlist but it doesn't seem to work. Any ideas or help appreciated.

function preMain()
{
    setCursorLabelName("Text",0);
    setDefaultBarFgColor(Color.white, 0); 
        
    setCursorLabelName("Length ",1);
    setDefaultBarFgColor(Color.white, 1); 


}

var Tot = new File( "Total/test.txt" ); 
Tot.mkDir(); 

var line="ini";
var Lngth=-11;
var rArray = new Array();

function Main()
{
    if (getBarState==BARSTATE_ALLBARS)
    {
        if( Tot.exists() ) { 
                                             
            Tot.open( "at+" );
            Tot.write("x");
            line=Tot.readln();
            Tot.close();  
            Lngth=Tot.getLength();                       
        } 
        else {
            Lngth=-9;
            line="! Exist";  
        }     
    }
    
    rArray[0]=line;
    rArray[1]=Lngth;
     
    
    return rArray;
}

Main() should be main()
