Abstract: Some three point difference schemes are considered for a singular perturbation problem without turning points. Bounds for the discretization error are obtained which are uniformly valid for all h and $\varepsilon > 0$. The degeneration of the order of the schemes at $\varepsilon = 0$ is considered.
