This is not a daemon:

while (1) {
    print "Enter a number: ";
    $Number = <STDIN>;
    chomp($Number);
    print "You entered - $Number.\n";
}

yet you would have me believe it is.

No, I don't consider that a daemon because it's actively soliciting information on a handle (or port, or file, etc...) as soon as it starts. I would however consider this to be a very simple daemon...

while (1) {
    $Number = <STDIN>;
    chomp($Number);
    print "You entered - $Number.\n";
}

...because it passively waits for a connection on a handle (or port, etc...) before doing anything. it's not a very useful daemon because it's single threaded ... but lots of daemons can run as single threads.

But none of this is really helping you achieve what you want, so i guess we'll just agree to disagree.

In the mean time, perhaps Proc::Daemon would be of interest to you?
