I have not read the code in this instance but I would normally interpret "non-positive response" to mean "RCODE is not NOERROR".

(There is a particular kind of response which is considered negative in some circumstances where RCODE == NOERROR and the answer section is empty, but I do not think this is one of those circumstances.)
