Abstract
In this paper we investigate an algorithm of approximation of defferential-difference equations by systems of ordinary differential equations. We investigate conditions for convergence of solutions of approximating systems to solutions of initial problem in a finite interval. The value of precision of approximation for different classes of function is obtained.
