We proposed a format for encoding chemical structural data including 2-dimensional coordinates, connection tables and auxiliary data for drawing chemical structures. This format named chemcode is defined independent of hardwares and softwares on which the chemical structure is built. We also developed programs to convert the structural data made by ChemDraw on Macintosh to chemcode and vice versa, and a program to draw chemical structure on CRT display of PC-9801(personal computer of NEC). Thus it was proved to communicate chemical structure between different computers.
