A measurement is presented of inclusive charged D*(2010) production from nonresonant e+e- annihilation in the center-of-mass energy (W) range 10.2 GeV<W<10.6 GeV. Charged D* mesons are identified by the decays D*+D0+K-++ and the charge conjugate mode. It is found that 40 ± 7 ± 13% of the charm quarks from the process e+e-cc result in D* mesons with z>0.7 (z=2EW, where E is the D* energy).
