Several path integrals are calculated for the heterotic string with the Green-Schwarz covariant action. It is shown that if supersymmetry is unbroken, the cosmological constant vanishes to all orders, and one-and two-particle S-matrix elements for massless particles recieve no loop corrections. In addition, the one-loop calculation at finite temperature gives the correct lowest-order free energy.
