Hi all I realy don't understand why I dont get "Global symbol "%CS101" requires explicit" when I run: 

#!/usr/bin/perl
#
use warnings;
use strict;
use Carp;
use 5.016;

ave();

my %CS101 =("Joe Below" => 100,
            "Dan Gold"    => 90,
            "Jon Kery"    => 40,
            "Elton Jon"    => 60,
);

sub ave {
    foreach (keys %CS101) {
        print $CS101{$_}, "\n";
    }
}    

1;

__END__
