Thanks, everybody!! I've declared the $n variable outside the subroutine, as
suggested, and everything works fine :-).

I believe when you have
sub marine{
my $n
}
my is local to sub marine, so it is lost after each call of marine. Whereas
in the second example you have my $n outside of sub marine.

Is it just me, or does anyone out there notice that the example subroutine
on pg. 57 of "Learning Perl" (Third Edition) doesn't work, as presented?
When written like:
snip--
#!/usr/bin/perl -w
use strict;
sub marine {
my $n += 1; # Global variable $n
prin
