The program of multislice calculations written by Ishizuka [User's Manual of Multislice and Image-Simulation Programs (1982). Center for Solid-State Science, Arizona State University, USA] for large central computers has been successfully transferred to the 16-bit PDP-11/24 minicomputer, without disturbing its features and capacities. The structural modifications of the transferred program lead to a great reduction of the calculation time for running on the PDP-11/24. The function of halftone output of calculated diffraction patterns has been developed and added to the package. This package proves to be especially effective in image simulations for complex structures (medium or large unit cells) on a minicomputer.
