Transfer from Turbo Prologa to Visual Prolog

There is an expert car troubleshooting system for the Turbo Prolog. The program asks questions, the person answers, and then we get the program's answer. What a problem is there in the car, according to its signs.
And there's a knowledge base.
The question is, help transfer the program to the Visual Prolog console. I'll pay a coin!

Program code on Turbo Prolog and knowledge base.
