multi-dimensional hashes

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi, Can anyone please explain how you can look up key-value pairs in a hash containing 2 values per key!? Preferably I would like to be able to access both values at the same time. My attempt doesn't work! Cheers monks :->

 my %energy_hash = map {$amount [$_] => [$chocolate[$_] => $sweets[$_]
+] } 0..$#amount;


 print $energy_hash {"10"}[1];

`my %mdhash = ( foo => [ qw( ichi ni ) ], bar => [ qw( san shi ) ], ); print $mdhash{foo}->[0], $mdhash{foo}[1], $/, @{$mdhash{bar}}[0], pop @{ $mdhash{bar} }, $/; __output__ ichini sanshi` [download] See. perlreftut and perlref for more info. HTH `_________ broquaint`	[reply] [d/l]
