We have investigated the origin of prompt muon production in the interaction of 400 GeV protons in a steel target. Using a variable density target and a large acceptance muon identifier, we have observed a substantial signal of prompt single muon for the kinematic region X/sub F/approx. =0 and 0.8< or approx. =p/sub t/< or approx. =1.5 GeV. Assuming that the major source is charmed DD-bar production, a model dependent calculation yields sigma (pp..-->..charm) of about 40..mu..b.
