For studying crystal structures, it is very useful to draw them from the various crystal-lographic directions. It can easily be carried out by a personal computer. A program “CRYSTAL” for drawing crystal structures has been developed on the NEC PC-9801 series personal computer with 640 KB main memory. The program is written by N88BASIC and it can display a crystal structure with either ball-and-stick model or polyhedral model on the color graphic display of 640x400 dots. In this paper the program is described and some results are demonstrated.
