// 12/12/01 - Chris - Changed the "reset the right hand page" link
//                    from:  rhsindex.html
//                    to:    ../rhsindex.html
//        Also tweaked bottom nav bar links slightly

// 12/9/01 - JS - Changed FUNCTION_CALL constant second argument from 'leftframe' to
//	'bod.leftframe' to comply with the new frame layout. (Also changed this value in
//	the anchors on the random pages.)

// %L - Last used arguments (not counting frame)
var FUNCTION_CALL = "javascript:top.bod.Generate(%L,'bod.leftframe')"
// %T - The title of the random search
// %I - Where the image and link is
// %J - The function call (do a similar search)
