Re: Multi Dimensional Hashes

If $returnedData is holding a reference to a hash, you can get the keys of the outer hash by using keys %$returnedData. I'm not sure about the inner hashes, but I think that you could use keys %$returnedData->{..}.

update: sorry, other replies came in while I was typing, that keeps happening to me.

I think that you could use `keys %$returnedData->{..}` Not quite. The rule is that it's sigil followed by block returning reference of the appropriate type, but the braces can be left off iff the reference is a simple scalar variable. So you can do `keys %$returnedData`, but you'd need the braces for `keys %{$returnedData->{...}}`. Otherwise, it would parse as `(keys %$returnedData)->{...}`, which is nonsense.

So would I be correct if I said that the `%{}` around `$returnedData->{..}` is getting the hash inside of `$returnedData->{..}`?	[reply] [d/l] [select]

I wouldn't word it exactly that way, but I think you have the right idea. the lowliest monk	[reply]
