Don't know Net::NNTPClient, but... The first two snippets are equivalent (the second one may occupy more memory since it build an array of the msgids) In the third one, you are saying: for each number between $first and $last, if that number is undef or the empty string... Since no number passes the test, @messages will not be altered (assuming that that @testlist should be @messages) -- dakkar - Mobilis in mobile In reply to Re: Usenet and arrays
