Preface to Version 13.1

Since the birth of PROPATH in 1984 as version 1.1, PROPATH has gained an increasing number of users distributed all over the world. The program package has made a good deal of contribution to activities in the fields of education, research and technology, our developing team of PROPATH believes with pleasure and pride.

In this latest version of PROPATH 13.1, new 26 P-PROPATH(pure substances) programs have been added on to the previous version of 12.1, based on the new formulations appeared in recent 10 years. May we remind you of the 2 features of W-PROPATH and E-PROPATH (both did appear at the previous version)? By the former, you may execute single shot programs of P- and A-PROPATH on Internet web page, and by the latter, on the other hands, you may incorporate PROPATH functions into your Excel sheets. All the members of PROPATH wish that this new version will find new and advanced users and appreciate creative suggestions and criticism to foster further developments of PROPATH.
