OK, once again. Here is the script for
you to look over before we go through it together.

<SCRIPT LANGUAGE="JavaScript">
<!-- Beginning of JavaScript -

function encode(text) { Ref="0123456789abcdefghijklmnopqrstuvwxyz.-~ABCDEFGHIJKLMNOPQRSTUVWXYZ"
Result=""
for (Count=0; Count<text.length; Count++) {

Char=text.substring (Count, Count+1);
Num=Ref.indexOf (Char);
EncodeChar=Ref.substring(Num+1, Num+2)
Result += EncodeChar

} document.form1.result.value=Result
}

// - End of JavaScript - -->
