To write messages to the screen without using "document.write()"?

Answer:

Changing the contents of an element is a much better solution. When the method showStatus is invoked it will change the content of the span.

function showStatus(message) {
var element = document.getElementById("mystatus");
element.textContent = message; //for Firefox
element.innerHTML = message; //for IE (why can't we all just get along?)
return true;
}
<span id="mystatus">Test. </span>
