#system() executes the external command after forking a separate process, and the main program waits for the child process to complete before continuing. exec() however, *never* returns so is used when you誶e finished with the original program. For both of these commands it is more efficient, and secure, to use the list form when passing arguments:
#system "/path/to/my/program.pl", $foo, $bar;
#instead of:
#system "/path/to/my/program.pl $foo $bar";
