We calculate the total inclusive ( p,..pi../sup -/xn) reaction cross section for 200 MeV protons on /sup 209/Bi using a simplified intranuclear cascade model in which only one particle at a time is tracked through the nucleus. Computer time is kept to a minimum by multiplying the very small NN..-->..NN..pi.. probability by a weighting factor. The nucleon and pion charge exchange mechanisms contribute more than half the cross section. The predictions are sensitive to choice of energy in the NN..-->..NN..pi.. input cross sections, but a reasonable choice gives cross sections in agreement with experiment. The predicted ( p,..pi../sup -/xn) cross section grows rapidly from T/sub lab/ = 160 MeV (just above threshold) to 220 MeV.
