Abstract
We present several results on hadronic D meson decays. We report on results from the scan of the energy region from 3970 MeV to 4260 MeV, which was used to determine an optimal energy to carry out the D_s physics program of CLEO-c. Improved measurements of inclusive and exclusive D and D_s branching fractions are presented. We also show results on Dalitz analyses of D^+-->pi^+pi^-pi^+ using CLEO-c data and D^0--> K^+K^-pi^0 using CLEO III data.
