Q700 How can I alter the contents of a layer in Netscape Navigator 4 using *.js source files to hold the text to be used in the layers?

<SCRIPT LANGUAGE="JavaScript"><!--
function over() {
    var text = '<FONT COLOR="red">Ha! You moved the mouse over the text<\/FONT>';
    document.layers['myLayer'].document.open();
    document.layers['myLayer'].document.write(text);
    document.layers['myLayer'].document.close();
}

function out() {
    var text = 'Move the mouse pointer over this text';
    document.layers['myLayer'].document.open();
    document.layers['myLayer'].document.write(text);
    document.layers['myLayer'].document.close();
}
//--></SCRIPT>

<LAYER ID="myLayer" onMouseOver="over()" onMouseOut="out()">
Move the mouse pointer over this text
</LAYER>

<SCRIPT LANGUAGE="JavaScript"><!--
var loaded = false;
//--></SCRIPT>

<SCRIPT SRC="over.js"></SCRIPT>
<SCRIPT SRC="out.js"></SCRIPT>

<LAYER ID="myLayer" onMouseOver="if (loaded) over()" onMouseOut="if (loaded) out()">
Move the mouse pointer over this text
</LAYER>

function over() {
    var text = '<FONT COLOR="red">Ha! You moved the mouse over the text<\/FONT>';
    document.layers['myLayer'].document.open();
    document.layers['myLayer'].document.write(text);
    document.layers['myLayer'].document.close();
}

loaded = true;

function out() {
    var text = 'Move the mouse pointer over this text';
    document.layers['myLayer'].document.open();
    document.layers['myLayer'].document.write(text);
    document.layers['myLayer'].document.close();
}

loaded = true;
