right then

two options for creating new proccess.

threads
OR
forking

forking is a bit of a more aggresive answer and takes the follwoing form

if( $pid = fork )
{
     # parent code here
     # proccess id avalibe in $pid
}
elsif
{
     # child here
     # parent processid avalible with
     # getppid()
}
else
{
     die "can fork() :".$!;
}

Threads

these are a more light wait answer but still only beta, well atleast in perl 5.005 and the perl build you have must be built for multi threading. see http://www.perl.com

# you can pass parameters to the function\sub as a second argument to the thread function.

$t = new Thread(mysub);

sub mysub()
{
     print("Heelo from mr thread");
}

this will create a new thread and the threads starting point will be mysub

there are quite a few thread functions for control etc see www.perl.com, you can get the module desciprtion etc....

hope this helps
