As a CGI, not really. Try:

<blockquote><table border=3 bgcolor=#000000><tr><td>
<script>
toolkit = java . awt . Toolkit . getDefaultToolkit ();
screensize = toolkit . getScreenSize ();
document . writeln
(
"<p>" +
"You screen is " + screensize . width + " pixels wide." +
"</p>"
);
document . writeln
(
"<p>" +
"You screen is " + screensize . height + " pixels tall." +
"</p>"
);
</script>
</td></tr></table>
</blockquote>

HOWEVER, The remote client must have JS enabled and have Java installed =/

Ok.. now how do I get the screen size info to a hidden input (in a form) or
send back to a cgi ?

I'm guessing as a hiiden input with in a form or as part of the link
command, which calls the game.cgi?W=Wvar&H=Hvar

"<p>" +
"<A HREF='game.cgi?W= " + screensize . width + "$H=" screensize . height
"'>click here</A>"+
"</p>"

yes ?yes? did I do it.. I really don't know JS : (
just guessing...

BTW .. thanks for your help!
Lou.

If you have a form that has a hidden field and you can rely on
javascript, you can set the values of hidden fields in the form by
something like:

<form name="anotherName">
<input type=hidden name="hiddenName" value="initial">
</form>

<script language="JavaScript"></script>

I found this on:
http://developer.irt.org/script/form.htm

Hope this does what you want.
