Popis:	We have measured charged multiplicities, inclusive branching ratios to states containing kaons, and average energy fractions in charged and neutral particles for decays of D mesons produced at the psi (3772) resonance. The average charged multiplicity is 2.3 +- 0.3 for both the neutral and the charged D. We find inclusive branching ratios B (D/sup 0/ ..-->.. K/sup + -/X) = 0.35 +- 0.10 and B (D/sup +/ ..-->.. K/sup -/X) = 0.10 +- 0.07 for decays into charged kaons.
