Why there isn't any function in perl that deletes everything in a hash, removes keys, and deletes it such that it is like just it was declered. How can i do this? The following code shows how I create the hash.

         $load_number_hash{$_} = $_;
        }

Use of uninitialized value in hash element at ...
