RE: marine subroutine

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.

Hi

I'm trying to understand subroutines.

#!/usr/bin/perl

&marine()

sub marine {
$n += 1; #Global variable $n
print "Hello, sailor number $n!\n";

}

This doesn't work. Is &marine() incorrect? How would I call the sub
marine?

Thanks

Amichai

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();
