We report on a search for the decay B+ -->- D*K-+(S)0, and its charge conju
gate with the CLEO detector at the Cornell Electron Storage Ring (CESR). No
candidates are found in 9.10 fb(-1) of data. The background is estimated t
o be 0.29 +/- 0.05 leading to an upper limit B(B+-->D*K-+(0)) = 9.5 x 10(-5
) (90% confidence level).
