  We present the results of complete tree level calculation for W boson
production processes e^- p -> e^- mu^+ nu_mu X and e^- p -> e^- mu^- nu_mubar X
introducing anomalous WWgamma and WWZ couplings. Detailed results for the
distributions of final state particles are obtained. In the region of small
momentum transferred we calculate the contribution of hadronlike photon
component in the structure function approach.
