[amibroker] Help to code a import JScript function

Help to code a JScript function to import close  quotes from a CSV format.

Here is an example showing four last lines from such a file:

Date,ticker1,ticker2,ticker3,ticker4
01/10/08,2307,1104,68,45
01/11/08,1175,2233,34,41
01/14/08,2354,1071,69,68
01/15/08,851,2581,25,35


How to change the following code to do this?

function ImportCSV( filename )
{
        var fso, f, r;
        var ForReading = 1;
        var AmiBroker;
        var ticker;
        var date;
        var quote;
        var fields;
        var stock;

        /* Create AmiBroker app object */
        AmiBroker = new ActiveXObject( "Broker.Application" );

        /* ... and file system object */
        fso = new ActiveXObject( "Scripting.FileSystemObject" );

        /* we use file name ( without extension ) as a ticker name */
        ticker = fso.GetBaseName( filename ).toUpperCase();

        /* add a ticker - this is safe operation, in case that   */
        /* ticker already exists, AmiBroker returns existing one */
        /* we are doing this outside loop since the file contains */
        /* quotes of single stock only */
        stock = AmiBroker.Stocks.Add( ticker ); 

        /* open ASCII file */
        f = fso.OpenTextFile( filename, ForReading);

        /* notify the user */
        WScript.Echo( "Importing " + ticker );

        /* skip first line which contains format definition */
        f.SkipLine(); 

        /* read the file line by line */
        while ( !f.AtEndOfStream )
        {  
                  r =  f.ReadLine();
                  
                  /* split the lines using comma as a separator */
                  fields = r.split(","); 
                  
                  /* split date at - separator */
                  var datefld = fields[ 0 ].split("-");

                  /* ensure Y2K compliance by converting year to 4 digit number 
*/
                  var year = parseInt( datefld[ 2 ] );
                  year += ( year < 50 ) ? 2000 : 1900;
                  datefld[ 2 ] = year.toString();

                  /* put date back all together */
                  datefld.join(" ");

                  date = new Date( datefld );

                  /* add a new quotation */
                  quote = stock.Quotations.Add( date.getVarDate() );
                  
                  /* put data into it */
                  quote.Open = parseFloat( fields[ 1 ] );
                  quote.High  = parseFloat( fields[ 2 ] );
                  quote.Low   = parseFloat( fields[ 3 ] );
                  quote.Close = parseFloat( fields[ 4 ] );
                  quote.Volume = parseInt( fields[ 5 ] );
                  
        }

        /* refresh ticker list and windows */
        AmiBroker.RefreshAll();

        /* notify the user */
        WScript.Echo( "Finished" );
