Your request for a shareware Prolog is a symbol of your individuality?
Maybe you've lived in America too long.

Anyway, there is a Prolog called PDPROLOG that runs on IBM PCs.  The low-end
version is public-domain; higher-level versions have increasinly higher costs.
The low end version seems adequate for instructional use.  Last I checked, it
was available via anonymous FTP from wuarchive.wustl.edu from the directory
/mirrors/msdos/prolog.
