This doesn't print the keys and values, but the values associated with the keys `key` and `value`. If you want to print the hash out for debugging purposes, use Data::Dumper. If you want to access the keys/values in your program, use `keys %{$data_pair}` or `values %{$data_pair}` instead.	[reply] [d/l] [select]
