Cross sections are presented for all final states without strange-particle production. Contributions to singlepion production are found from (i) A(1238)1r, (ii) p'p, (iii) nucleon diffractive dissociation into NT, (iv) ~* ( 1 6 8 8 )~+ , and (v) "phase space." Processes (i), (ii), and (iii) are studied in some detail taking into account overlaps between the various subchannels.
