That is code from Lincoln Steins excellent book Network Programming with Perl. Briefly: read about file handles the non OO way. Then read about IO::File and IO::Socket. Both inherit most (all) methods from IO::Handle, thus making the scource of your input / the destination of your output pretty arbitrary. ie: reading from a socket is no more difficult than reading from a file. and: www.perldoc.com Enjoy, Wolf -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
