We present the Monte Carlo program BHAGEN95, for calculating thecross-section of the Bhabha scattering process at LEP1/SLC and LEP2 energies,usable with continuity from small to large-angle configurations. We discusssome improvements in the event generator BHAGEN94, which is now part of the newcode. In particular the weak and QCD corrections are implemented up to twoloops for the relevant contributions, and the emission of one hard photon istreated exactly. We have included all the radiative corrections which arenecessary to obtain, for a typical experimental event selection, a precision of0.1-0.2% at small-angle. At large-angle we estimate a precision of 0.5%, withthe exception of the region where the beam energy is a few GeV above the Zboson resonance, where it is up to 1%. A detailed comparison with other codesfor both small-angle and large-angle Bhabha scattering is performed.Comment: 24 pages, Latex, 4 composite Postscript figures, uses epsfig.st
