Try reading about Slices in 'perldata'.
Basically, when referring to a single value in a hash you
use the scalar prefix '$'.
my %hash = ( foo => 'baz', bar => undef );
print $hash{foo};
delete $hash{bar};
When referring to a list of keys use the array prefix '@'.
$hash{bar} = 'one';
print "$_\n" foreach @hash{ qw| foo bar | };
@hash{ qw| foo bar | } = @hash{ qw| bar foo | };
When referring to the entire hash use the hash prefix '%'.
print "$_\n" foreach @hash{ sort keys %hash };
print "$_\n" foreach sort values %hash;
