in thread How do I get the child's data?

Thanks, this looks like what I ought to do. I don't really understand
print "$$: ", int rand 0x7FFFFFFF, "\n";

    print "$$: ", int rand 0x7FFFFFFF, "\n";

    ...Is just some random data to show that your child process is doing something.
    $$ is the process ID of a process (in this case the child process).
