Continuous approximations to the solution of systems of Volterra integral equations of the first and second kinds are sought by methods using spline functions of degreem, deficiency-(k—1), i.e. inCm—k, and a fixed quadrature rule of degreep-1,p≥m-1. The resulting method is called an (m, k)-method. The stability behaviour of the (m, 1)- and the (m, m)-method is studied for arbitrarily finitem. Also studied is the stability of the (m, m-1)-method for second-kind systems. Convergence results and asymptotic formulae for the discretization error are obt
