We have searched for the lepton-flavor-violating decay D/sup 0/..-->..e/sup +- /..mu../sup minus-or-plus/ in 204 pb/sup -1/ of e/sup +/e/sup -/ annihilation data at E/sub c.m./ = 29 GeV from the Mark II detector. No candidates were found; we estimate an upper limit on the cross section times branching ratio of sigma(e/sup +/e/sup -/..-->..D/sup 0/,D-bar/sup 0/; inclusive)B(D/sup 0/..-->..e/sup +- /..mu../sup minus-or-plus/)<0.35 pb at the 90% confidence level. Simple assumptions yield the rough limit B(D/sup 0/..-->..e/sup +- /..mu../sup minus-or-plus/)<2.1 x 10/sup -3/. AE.
