    Description:  

       This script is backwards-compatible for creating popup windows.
       Any version 3+ browser will support the javascript features used
       to create a new window with the parameters specified, unsupported
       browsers will create a new window as if target="_blank" were used.

       Opening a page in a new window:

           <A href="PAGENAME" target="popup:width=400,height=400,toolbar">LINK</A>

       Opening a page in an existing window:

           <A href="PAGENAME" target="popup:width=400,height=400,toolbar:WINDOWNAME">LINK</A>

       "WINDOWNAME" is that name of the target window,
       "LINK" is the linkable image or text content and
       "PAGENAME" is the name of the page to be loaded

       The script also contains NewPopUp() a function for manually calling
       a new popup window.  This script is useful for creating windows
       triggered by events, such as onload or onunload.

// This function must be called from the onload for the AutoPopUp() function to operate
// This function traverses the page links and any link whose target contains the string 
// "popup" gets an onclick attribute whose action is the AutoPopUp() function.

    var link;

        if (link.target && link.target.indexOf("popup") == 0) link.onclick = AutoPopUp;
    }
}


// This function is called by the onclick event assigned to a link by the SetAction() function
// The function parses the caller link's target value extracting the window parameters and name
// values.  If no values are defined, a random number is assigned for the window name, and
// the window's parameters are assigned generic values.
