in thread output to screen in real time (CGI)

Another means of doing this is server-push, last I checked it was only supported by Netscape though (it uses the multipart/x-mixed-replace MIME-type).
A different method, for IE, is to use client-pull with the active-x object Microsoft.XMLHTTP. As bad as A-X is security wise, this one seems the most benign. Of course, this requires some client-sever communication: Either you need to separate all of your subs, and call each cgi separately, or pass a q-string down to the server and route the cgi execution based on the parameter:

Accessed via javascript:
<script language=javascript> var url="nameOfCgi.pl" var httpObj = new ActiveXObject('Microsoft.XMLHTTP'); httpObj.open (GET,url,false); httpObj.send(); return (httpObj); //httpObj.responseText contains the returned html. </script>
