Depends on the OS. Under Unix Perl's exec() is the exec you are looking for. Under Windows it's implemented some other way. With functionality as similar to the Unix implementation as possible. Which doesn't say that much. Basicaly it just starts the other program and exits. So the process ID will be different and I'm not entirely sure about the filehandles.
