The spacing in some of the code examples is messed up. Look at this from
http://www.gammon.com.au/scripts/function.php?name=GetWorld :
<pre><font size=2>' --------------------------------------------------^M<br />
' Example showing sending a message to another world^M<br />
' --------------------------------------------------^M<br />
The code is enclosed in <pre> but it *also* has <br/> tags in addition to the line feeds which makes it do two newlines instead of one. Then, the ^M makes it do another newline in Opera 6.01 (but not Netscape or IE).
It should probably be like this (without the <br/> and without the ^M):
<pre><font size=2>' --------------------------------------------------
' Example showing sending a message to another world
' --------------------------------------------------
