32 bit personal computer version of the DIRECT-SEARCHER system

A new version of DIRECT*SEARCHER (DIRECT-SEARCHER automatic system) for personal computers (PC) consisting of several crystallographic programs has been developed for automatic structure analysis of organic compounds as an innovation of the DS*SYSTEM [Koyama & Okada (1975). Acta Cryst. A31, S18]. Each program is improved and rewritten in Fortran77 for the 32 bit PC. The PC version of DS*SYSTEM is used by organic chemists rather than professional crystallographers.
