In following code, the atEnd method is used to determine if the end of a list of drives has been reached:
function ShowDriveList()
  var fso, s, n, e, x;
  fso = new ActiveXObject("Scripting.FileSystemObject");
  e = new Enumerator(fso.Drives);
  s = "";
  for (; !e.atEnd(); e.moveNext())
    x = e.item();
    s = s + x.DriveLetter;
    s += " - ";
    if (x.DriveType == 3)
      n = x.ShareName;
    else if (x.IsReady)
      n = x.VolumeName;
      n = "[Drive not ready]";
    s +=  n + "<br>";
