1 is just the return value of the function ("thaw" in your case cause it's processed after "freeze") when it succeeded the module is changing %hashref or @hashref, you should use the strict pragma which should throw an error on your use of $hashref as it pretty much looks alike a hash So better print out the scalar, array or hash when you've frozen it and thawed it again to see how it works. Have a nice day All decision is left to your taste Update You might consider to use module Storable as well. And no, don't rely on my first sentence, I was wrong, the 1 is the length of the returned array as described below.
