That's rubbish,
You can call a sub before you create it as you say. At compile time the
entire code is done (bar some exceptions)
The issue here is drop the & unless you really know what it does
my($n);
marine();
sub marine {
$n += 1;
print "Hello, sailor number $n!\n";
}
Works fine.

You can't use somting BEFORE you have created it try to call and call sub
with name and () and ;
sub marine {
$n += 1; #Global variable $n
print "Hello, sailor number $n!\n";
marine();
