// DisplayMsg()
// ----------------------------------------------------------
// Display MessageText in the navigator window status bar, if the
// browser supports such status messages. In the HTML code, it must be
// followed by "return document.returnValue" or "return true" in order
// for the message to be displayed.
//
// Example:
// -> Displays "This is a link" in the status bar when the mouse is
// over the hyperlink to the file link.html.
//
// NOTE: Netscape only supports the onMouseOver event for the tag
var MessagesAllowed = navigator.userAgent != "Mozilla/4.0 (compatible; MSIE 4.0; Mac_PowerPC)";

// LoadImage()
// ----------------------------------------------------------
// Load "on/off" image files associated with ImageName into ImageObject
//
// - ImageName is the "root" name associated with the file, and is the
// name that appears within the ![]()
tag in the HTML
// source.
// - The files are of the format [ext], usually "gif" or "jpg,"
// and reside in the /img/ directory.
//
// Example: LoadImage('Button','bluebutton','gif');
// -> Creates an object called Button that is associated with
// the images bluebutton_on.gif and bluebutton_off_.gif. In the
// HTML code, the image would be named "bluebutton" like this:
// ![]()

// TurnOn()
// ----------------------------------------------------------
// Replace the on-screen image associated with ImageObject with its
// highlighted version.
//
// Example: TurnOn(Button);
// -> Assuming Button is the same object as with the last example,
// this replaces bluebutton_off.gif with bluebutton_on.gif.
function TurnOn(ImageObject)

}
// TurnOff()
// ----------------------------------------------------------
// Return the highlighted image associated with ImageObject to
// its "normal" state.
//
// Example: TurnOff(Button);
// -> Assuming Button is the same object as with the last two examples,
// this replaces bluebutton_on.gif with bluebutton_off.gif.

// RollOn()
// ----------------------------------------------------------
// Handles OnMouseOver routines that apply Style Sheet changes,
// such as highlighting a link.
//
// Usage in HTML document:
function RollOn()
{
if (window.event.srcElement.tagName != "A") return;
if (window.event.srcElement.className == "")
window.event.srcElement.className = "Happy";
}
// RollOff()
// ----------------------------------------------------------
// Handles OnMouseOut routines that apply Style Sheet changes,
// such as returning a highlighted ("Happy") link to normal.
//
// Usage in HTML document:
function RollOff()
{
if (window.event.srcElement.className == "Happy")
window.event.srcElement.className = "";
