// This multifunction program:
//      1.0 Positions a hyperlink "Up-Arrow.gif" on the lower right hand
//      margin of the hosted page, out of the view as the host page is
//      loaded. Scrolling down the host page enables the display of the
//      "Up Arrow.gif". Clicking on the image, repositions the host page
//      to the original position.
