Re^2: Difference Quantity of two Arrays

Thank you for your explanation.

My Perl book says, that delete deletes a key value pair. But it doesn't tell me why I have to use @dbs{@_} instead of $dbs{@_} (which apparently does nothing) or %dbs{@_} (which throws a failure) to get the thing working. Can you explain? :)

`$` means you're working with one element. `@` means you're working with multiple elements. `@hash{@list}` is a hash slice. It amounts to `map { $hash{$_} } @list` but can be used as an lvalue. `$hash{@list}` is the same as `$hash{join($;, @list}}` It's a means of doing Hash of Hashes without actually using Hash of Hashes. It's generally unused.	[reply] [d/l] [select]
