The equilibrium and stability of a straight, two-dimensional, l=1 plasma configuration in which no net longitudinal current is allowed to flow on any flux surface has been examined numerically. It is conjectured that equilibria exist and are unique for parameter ranges far in excess of those of physical interest. The δW stability analysis is done in the slow z variation limit and predicts gross modes which are qualitatively and quantitatively similar to the sharp boundary theory. In addition, other modes with higher nodal structure are found but appear to be stable.
