In this paper we compare recent experimental data for the total cross section #sigma#(e"+e"- #->#hadrons) with the up-to-date theoretical prediction of perturbative QCD for those energies where perturbation theory is reliable. The excellent agreement suggests the determination of the strong coupling #alpha#_s from the measurements in the continuum. The precise data from the charm threshold region, when combined with the recent evaluation of moments with three loop accuracy, lead to a direct determination of the short distance anti M anti S charm quark mass. Our result for the strong coupling constant #alpha#_s"("4")(5 GeV)=0.235_-_0_._0_4_7"+"0"."0"4"7 corresponds to #alpha#_s"(...
