Re^4: Appending values to existing hash key

The statement :

   join( ', ' => map { $_, @{ $hash{$key}{$_} } } keys $hash{$key} ), 
+$/;
[download]

should read:

   join( ', ' => map { $_, @{ $hash{$key}{$_} } } keys %{ $hash{$key} 
+} ), $/;
[download]

Nice shortcut (++) - nesting the hashes !

What is the sound of Perl? Is it not the sound of a wall that people have stopped banging their heads against?

Thanks NetWallah for the extra eye! Staying up too late with C is not helping! And so do perl version 5.16.1! Am downgrading to v5.8.1! Lol :) If you tell me, I'll forget. If you show me, I'll remember. if you involve me, I'll understand. --- Author unknown to me	[reply]
