A Note on `A Modification of Nordsieck's Method Using an `Off-Step' Point'.

The article presents information on the experimental results presented by researchers J.J. Kohfeld and G.T. Thompson in their paper on a modification of Reinhard Nordsieck's method for the numerical solution of ordinary differential equations using a multiple precision arithmetic package available on the IBM 7094 at the Ohio State University Computer Center in Columbus, Ohio. The experimental results agree with those presented by Kohfeld and Thompson at h = 0.10 and 0.15 for the Nordsieck and the GSN methods, which is to be expected since round-off error is not critical at those interval lengths.
