Nature of physical problem:
A leptoquark generator in electron/positron-proton scattering is presented. The generator allows to simulate leptoquark mediated processes involving any quark generation in the initial and final state and any lepton generation in the final state.

Method of solution:
The model used for the process generation is based on an effective Lagrangian which respects the Standard Model symmetries and conserves lepton and baryon numbers. The Pythia library must be linked; in particular the generator is designed to be interfaced with the Pythia version 6.1 [1]. In addition the PDFLIB [2] (which is a compilation of the different parton distribution function parametrizations) and the CERN libraries PACKLIB [3] (which contains the used HBOOK [4] histogramming package) and MATHLIB [5] must be supplied.
