  We present the results of an analytic next--to--next--to leading order QCD
calculation of the non--singlet anomalous dimension $\gamma_{\rm NS}^+(N)$ and
the coefficient functions $C_{2,L}(N)$ associated to the deeply inelastic
structure functions $F_2(x,Q^2)$ and $F_L(x,Q^2)$ for the Mellin moment N=16.
Comparisons are made with results in the literature.
