Re^2: Multi Dimensional Hashes

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]
