There is no way to call a subroutine and have it return immediately yet still do productive work in the background without using some sort of multi-tasking, i.e., forks or threads, on a single, normal computer. Starting a separate process using fork is relatively easy. The problem is figuring out when the forked process is done and getting information back from it to the main program. See ‘perldoc perlipc’ for ideas on creating and communicating with separate processes. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
