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