Hi!
If I want to print out every value of a hash, what's wrong with doing 
it like that:

foreach (keys %hash) {
    print $hash{$_};
    print "\n";}
Why do I only get one value???


probably because there is only One Value in the hash?

        my %hash =  qw/ a b c d e f g h/ ;
        
        print "$_ => $hash{$_} \n"
                foreach (sort keys %hash);
will generate:
        a => b
        c => d
        e => f
        g => h
so if your code is only getting ONE iteration through
the loop, then %hash has only one key in it.
