Re^2: Truthfulness of references

So I should use:

if ( %$hash_ref )

to check whether the hash is empty or not?

By the way, thanks for your reply on this. I haven't used the Chatterbox before, so I wasn't sure how to respond ( I've been meaning to read up on it, but haven't found the time ).

Yes, when `$hash_ref` holds a reference to a hash. If `$hash_ref` doesn't hold a reference to a hash, you'll get a warning or a runtime error depending on what it holds and whether `use strict 'refs';` is active or not.	[reply] [d/l] [select]
