The paper presents the algorithm and description of the meigval procedurewritten in FORTRAN 90 language which was designed for calculation of themaximum eigenvalue of transfer matrix for one-dimensional S = 1/2 Heisenbergmodel. The procedure is available at the Poznań Supercomputing and NetworkingCentre on a Cray J916 supercomputer in the numerical procedure library/ l i b / m e s t a t . a .
