Abstract The order $\textit{p}$ which is obtainable with a stable $\textit{k}-step$ method in the numerical solution of $\textit{y′}$ = $\textit{f}(\textit{x},$ $\textit{y})$ is limited to $\textit{p}$ = $\textit{k}$ + 1 by the theorems of Dahlquist. In the present paper the customary schemes are modified by including the value of the derivative at one “nonstep point;” as usual, this value is gained from an explicit predictor. It is shown that the order of these generalized predictor-corrector methods is not subject to the above restrictions; stable $\textit{k}-step$ schemes with $\textit{p}$ = $2\textit{k}$ + 2 have been constructed for $\textit{k}$ ≤ 4. Furthermore it is proved that methods of order $\textit{p}$ actually converge like $\textit{hp}$ uniformly in a given interval of integration. Numerical examples give some first evidence of the power of the new methods.
