In a large-acceptance spectrometer at Fermilab, we have searched for multimuon events produced in collisions of 225-GeV/c protons and ..pi../sup + -/ mesons with nuclei. In particular, additional muons accompanying the J/psi..--> mu mu.. decay could signal charmed-particle production. For all data combined, the 90%-confidence limit on charmed-particle production in association with the psi is sigma/sub J C C//sigma/sub J/<0.01; the limit on production of J/psi pairs is sigma/sub J J//sigma/sub J/<0.021. Limits are also given for each beam particle separately.
