review text: Resistive instabilities may be controlled by a wall stabilization or magneto-viscous damping. From a mathematical model based on MHD equations involving resistivity and parallel ion viscosity, a special purpose computer code has been developed to trace the disturbances of cylindrical equilibria surrounded by conducting walls. Another code, using general purpose collocation software to exploit robust time integrators via the numerical method of lines, may be extended to more sophisticated models. Magneto-viscous reduction of resistive growth rates, due to parallel ion viscosity and independent of conducting wall stabilization, is most pronounced for smaller axial wavelengths and higher plasma temperatures.
