A note

Hi,

I am learning Prolog from "Laern Prolog Now" and Amzi's tutorial
"Adventure in Prolog" (both are very good!).

My Prolog environment was SWI. But when I tried to use "assert" and
"retract" commands (or should I use another term?) in SWI, it did not
accept them. That made me really sick.

One day, I saw a note in the Internet and the problem was solved.

I added a " :- dynamic blah/1, blahblah/2 " on top of the Prolog
program.

It looks that there is a minor difference between Amzi's Prolog and
SWI.

Hope that helps other people experiencing the same problem.

Ciao.
