That was close. Here are some statements to help you out
my @arr = ();
push @arr, {}; # push an empty hashref onto the array
my $href = $arr[0]; #copy the reference
$href->{foo} = 'bar';
print ${$arr[0]}{foo}; #same as previous line
print $arr[0]->{foo}; #same again
$arr[0]->{baz} = 'swing it';
print $href->{baz};
for (keys %{$arr[0]}) { print "$_\n" }
for $href(@arr)
{
for $key(keys %{$href}) { printf "%s\t%s\n", $key, $href{$key}}
}
Take a look at the perlref and perlreftut pages of the docs. If you
have activestate installed with the defaults start at
c:\perl\html\index.html
