✦ Synopsis

CERN experiment WA89 uses a E-beam at 340 GeV/c to study the production of charmed particles. Based on the reconstruction of all final charm states from the full data sample of our '93 and '94 beamtimes the total c~-cross section has been determined. Production of particles which have a light quark in common with the beam is compared to production of those which do not. Considerable production asymmetries between D-and D + , D s and D +, and Ac and A--c are observed.
