Abstract
Algorithms of two programs for computing the functions introduced by V. A. Fock are described. Estimates are given of the accuracy of the algorithms applied, and results of numerical computations of Fock functions on the basis of these programs are presented. The application of the programs constructed to compute diffraction fields according to two distinct asymptotic formulas is demonstrated.
