// OK, I write my function:

function CoordinatesArray(event:Event):void {
var xCoordinatesArray:Array = loader.data.xCoordinate.split(",");
var yCoordinatesArray:Array = loader.data.yCoordinate.split(",");
trace("The first number in the xCoordinates array is: " + xCoordinatesArray[0]);
trace("The first number in the yCoordinates array is: " + yCoordinatesArray[0]);
}

// Now, I want to run it (once)…

CoordinatesArray();

// Cheers!
