Abstract (2. Language): 
In this article a numerical method involving classical finite difference scheme on non-uniform grid is constructed for a singularly perturbed convection-diffusion boundary value problem with two small parame- ters affecting the convection and diffusion terms. The scheme has been analyzed for uniform convergence with respect to both singular pertur- bation parameters. To support the theoretical error bounds numerical results are presented.
