The stability of multihelical tearing modes in tokamaks with shaped cross sections is determined numerically. The method allows inclusion of a large number of singular surfaces resolved with high accuracy. Poloidal and radial couplings are discussed and the convergence is well understood. Modes of high poloidal m number are found to be unstable for typical equilibria. Completely stable current distributions have been constructed for D-shaped plasmas.
