Sorry I'm not K.C. Wang but I am one of his student. Cosh is a now an ordinary programmer.
I modified professor Wang's UPOS and republished it to my Github page.

Thanks for the clarification.  I read," * Author:      K.C.Wang; cosh.cage#hotmail.com" in
several of your Github files and assumed they were the same person.  My mistake.
