'The World' project ('WP.BAP' in the '/BAP/WORLD' directory) is an example for object based programming (without inheritance) from early experiments with the paradigms on parallel systems.
Load the world with:
cd ('/bap/world') load (wp)
and start it with:
wp_world % starts a continous 'put_on()' demo
wp % starts the natural language interface and % interprets the 'wp_in.in' file.
The demonstration runs independently, displaying a little graphic output.
Although an interesting approach to object based Prolog, the world does not do much in parallel, most actions run sequentially, causing a lot of communication.
