Re: Re: Re: quick question about hash element access

Interesting. But I have a question (not being totally fluent in references).

What exactly does the $thingy = $$thingy{$key} line do? My guess is that it assigns a scalar value referred to by the reference which is contained in $thingy{$key}. But I'm not even sure that sentence makes sense, much less if it's accurate. :)

you are correct sir- we are assigning `$thingy` to the value of whatever is refered to by `$thingy{'a'}`, in this case, it's the next hashref. this assignment is just repeated a few times till we're all out of keys. what's bad about this is that it assumes the caller will pass in a valid path. i guess error checking will be left up to OP...

`$$thingy{$key}` is equal to `$thingy->{$key}`, so it returns the value corresponding to the key `$key` in the hash pointed to by the reference `$thingy`.	[reply] [d/l] [select]
