Gnu prolog as rule evaluator for small C virtual-world game.

[tvetunge]

Hi.

I've asked this thing before, but got no answer.. I'll try making it brief;

How do I make a program able to interoperate with gnu-prolog as if the program
itself was the user?

I am trying this with C, to make it easier for myself.
I am aware of Pl_Query, the problem is that I do not know in advance 
(compile-time)
which facts will be asserted to prolog.
I am only trying to add new facts runtime, not present new queries.

Example:
During play, it is suddenly decided that due to game-balance, some of the
players should have more money.
So the following new facts should be added to the rule engine:

'credits(player1,1000)'
'credits(player2,1000)'
...
'credits(player100,1000)'

How can I state these facts to prolog runtime?


Regards, 
  Uffe Wassmann.
