The paper presents the algorithm and description of the meigval procedure written in FORTRAN 90 language which was designed for calculation of the maximum eigenvalue of transfer matrix for one-dimensional S = 1/2 Heisenberg model.The procedure is available at the Poznań Supercomputing and Networking Centre on a Cray J916 supercomputer in the numerical procedure library /lib/mestat.a.
