Nature of problem:
A Monte Carlo event generator simulating neutral and charged current ep interactions at HERA energies and beyond is described. The present version 4.0 of the generator optionally treats the ep scattering either by means of structure function parameterizations or on the basis of parton distribution functions in the framework of the quark-parton model. Single photon emission from the lepton line as well as self energy corrections and the complete set of one-loop weak corrections can be included. These corrections are sufficient to describe the cross section with an accuracy of a few percent or, if Q**2<= 2X10**3 GeV**2, of less than 1%.
Monte Carlo generator.
Depending on the actual requirements (parameters, requested contributions, kinematical limits, initialization); typical example: 1000 radiative events/5 seconds CPU. For a more detailed discussion see section 6.
