I'd say KI> that's a separate use, but of course Uri can judge. i have never run into a situation where i may process some items and later some more and need to track them with a hash. it doesn't mean that isn't a good use but i don't see why it couldn't be done differently. then again, i eschew else clauses which is rare. i just seem to code in a way that i very rarely need them. and i am not talking obscure code, just judicious use of statement modifiers, subs, logic order that generally eliminates the need for else. others will use else as they please. thanx, uri -- Uri Guttman ------ [EMAIL PROTECTED] -------- http://www.stemsystems.com --Perl Consulting, Stem Development, Systems Architecture, Design and Coding- Search or Offer Perl Jobs ---------------------------- http://jobs.perl.org
