We present the computation, in lattice QCD, of the renormalization constants and mixing coefficients of operators that measure the first two moments of DIS Structure Functions. These calculations have been performed using the Sheikholeslami-Wohlert O(a) improved ``clover'' action, which is known to reduce the systematic error associated with the finiteness of the lattice spacing a. Due to the complexities of the computations, we have developed, using the computer languages Schoonschip and Form, general codes that are able to automatically carry out all the analytic lattice manipulations.
