Hello I've been using perl for a few months now and am getting the hang of it real good. I was reading about some modules like IO::socket; but I'm confused how would you go about the module using for various things, like constructing simple program that does password guessing, I just need how the module and how to use it really, and also how or what do you use this arry for @ARGV. I've examined a few scripts and they use that array and also they a extract i don'w know what but its in this form:

$server = $ARGV[0];
$folder = $ARGV[1];
$user_id = $ARGV[2];

what does that mean or how do you use it, its giving me a little trouble and I can't find it anywhere in the book im reading.
