Not exactly, it has been forked and does technically run in parallel, however 'system' blocks your current process waiting for the child to finish, so your process is in fact running, but it won't be doing any work except for waiting for a signal from the child. There are other ways to have parallel execution, perldoc perlipc perldoc -f fork perldoc -f system Will get you started. "Network Programming with Perl" by Lincoln Stein also has excellent chapters on this subject, though lacks a chapter (probably because of its age) on POE. http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
