Hello tamaguchi
First of all, welcome to the monastery! We will try to help you with most of your Perl related questions (and some non-Perl related questions too). For getting a quick grip on references, I suggest tyes References Quick Reference.

I saw that you changed your title from "Hello All" to "hash of arrays to a subrutine?" - this is very good. The choice of a good title helps the readers to quickly understand your question and also helps you, the author, to take a step back and reflect on what your question actually is.

Update: I completely forgot to add a simplicistic example of how to pass a hash of arrays to a subroutine:

my %players = (
  frodo   => [ 'ring', 'chainmail armour' ],
  sam     => [ 'lembas', 'chainmail armour' ],
  smeagol => [ 'fish', 'rabbit' ],
);

# Pass the hash as a list:
sub print_players {
  my (%players) = @_;
  for my $player (keys %players) {
    printf "$player: %s\n", join ",",@{$players{$player}};
  };
};

# Pass the hash as a reference:
sub print_players_ref {
  my ($players) = @_;
  for my $player (keys %$players) {
    printf "$player: %s\n", join ",",@{$players->{$player}};
  };
};

print_players(%players);
print_players_ref(\%players);
