Abstract
A FORTRAN program is presented which solves the Sturm-Liouville proble m for a system of coupled second-order differential equations by the f inite difference method of the second order using the iterative Richar dson extrapolation of the difference eigensolutions on a sequence of d oubly condensed meshes. The same extrapolational procedure and error e stimations are applied to the eigenvalues and eigenfunctions. Zero-val ue (Dirichlet) or zero-gradient (Neumann) boundary conditions are cons idered.
