The SELEX experiment (ET781) [1] at Fermilab is a new fixed target multistage spectrometer with high acceptance for forward interactions and decays. It took data in 1996-97 with 600 GeV {sigma}{sup -}, {pi}{sup -} and 540 GeV p beams, collecting large sample of charm decays. Preliminary results on charm--anticharm production asymmetries, {lambda}{sub c}{sup +} production x{sub F} dependence in different beams, {lambda}{sub c}{sup +} lifetime, and the first observation of the Cabibbo-suppressed decay {xi}{sub c}{sup +}{yields}pK{sup -}{pi}{sup +} are presented.
