A Monte Carlo program was described for the simulation of point defect diffusion interaction in diamond and zinc-blende structured crystals. The simulated defects comprised vacancies, host or impurities. Several diffusion mechanisms, such as vacancy first and second neighbor hopping, the Frank-Turnbull and the kick-out hypothesis were simulated. The program could simulate various models with different parameters, diffusion activation energies, etc. Thus, the evolution of an initial defect configuration - as fed into the program - could be monitored in space and time, giving insight into the simulated model and the relationship between atomic level assumptions and macroscopic observables. The program was suitable to run on microcomputers in background at very low cost and was available to the reader at minimal cost.
