Proton--antiproton interactions at 0.943 to 1.098 GeV/c were studied in the final states anti pp $pi$$sup 0$, anti pn $pi$$sup +$, anti np $pi$$sup -$. The main concern is to obtain results for comparison with current algebra predictions for soft pion emission. The invariant-mass plots are discussed. An enhancement is found which may be due to the S(1930). The limited statistics suggest the enhancement to be in I = 1. (JFP)
