Subject: Re: hash missing value

Hi,

I think it is already there.  If you first declare the hash with

    files = Hash.new ("Untitled")

then you will get "Untitled" instead of nil for any missing key.  (But of
course, then you cannot create and populate the hash at the same time :)

Regards,

Bill
