// Though set in the JS1.2 code, these variables are declared here to avoid errors in lesser browsers
var width=null;
var height=null;
var right_browser=false;
// Called by Requirements button
function aboutScheme()
{
alert("\nThis example uses screen.height & screen.width to grab the screen resolution.\n\nThese were introduced in JavaScript1.2.");
}
// Called by View Source button - displays text file of source.
function viewSource()
{
alert("\nA text file with source will be loaded to the full window.\n\nUse your browser BACK button to return to the examples.");
top.window.location.href="js-wid3.txt";
