   <hidden TTP02-19  Towards deep-inelastic structure functions at three loops >  We report on the status of the calculation of deep-inelastic structure
 functions at three loops in perturbative QCD. The method employed allows
 to
 calculate the Mellin moments of structure functions analytically as a
 general
 function of N. As an illustration, we present the leading fermionic
 contributions to the non-singlet anomalous dimension of F_2 at three loops
 and,
 as a new result, to the non-singlet coefficient function of F_2 at three
 loops.
