What I have found to be the easiest means of doing this is
to give your submit button a name attribute like so:
<input type=submit name=in value="Format HDD">
And the browser will submit a in=Format%20HDD
key-value pair to you. So upon loading you look for
this key and value and if you have it you've been submitted.
Pseduo-code follows.
#use CGI or whatever;
if( $param{in} eq 'Format HDD' ){
#process form submission
#redirect elsewhere or print status screen
}
else{
#print form
}

perl -p -e "s/(?:\w);(<A HREF="/index.pl?node=st&lastnode_id=3333">st<
+/A>)/'\$1/mg"
