COSMOS is an object-oriented Knowledge Based System building Tools (KBSTs) to solve problem in engineering industry. COSMOS stands for C++ Object-oriented System Made for expert System development.

In order to provide more people those who don't have a Sun workstation to use this expert system, our task is porting COSMOS form UNIX to DOS.

Because the differents of workstation environment, the user interface and structure of original COSMOS no longer can be used, therefore we made some necessary change before we porting it to IBM Personal Computer.

In stead of X Window system®, we implemented ObjectWindows® runs on Microsoft WindowsTM. substitute AT&T C++ with Borland® C++, and because YACC is not a standard feature of DOS we consider the Window of Inference Engine Monitor as an independent object, create it by either system call or makefile at run time.
