note BrowserUk <p>Your problem is that you are trying to use perl as if it was C. <P>This:<code> sub protocol($srv) { </code> <p>Does not declare a function that takes a single argument called <c>$srv</c>. <p>You need to learn how to use perl before you start playing with threads; otherwise you will just blame threading for your own mistakes. <p>You should start by reading [http://perldoc.perl.org/perlsub.html|perlsub] and writing some simple (non-threaded!) programs that use subroutines and pass arguments. <p>Once you understand how to pass arguments and what "prototypes" are, you may be ready to progress to the next level. <div class="pmsig"><div class="pmsig-171588"> <hr /> <font size=1 > <div>With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'</div> <div>Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.</div> <div>"Science is about questioning the status quo.
