list or undef is determined by the caller's context.

When you call you
Hey,
I have a subroutine
sub displayPage($) {
my($server) = shift;
print $server;
}
Which I can call using displayPage("servername");
My question is lets say I wanted to pass a password as well. So I would like to
call it as displayPage("servername","mypassword");

Hi!
Theoretically, yes, of course I could just try to create an arbitrary
sized file from /dev/urandom via dd. I hoped there would be an equally
