We define some new polynomials associatedto a linear binary code and a harmonic function of degree k.The case k=0 is the usual weight enumerator of thecode. When divided by (xy)^k, they satisfy a MacWilliamstype equality. When applied to certain harmonic functions constructedfrom Hahn polynomials, they can compute some information on theintersection numbers of the code. As an application, we classifythe extremal even formally self-dual codes of length 12.
