My program works just fine in SWI-prolog. Does VP really consider my
design to be that flawed?

Traditionally Visual Prolog was a language quite distinct from
Standard Prolog...

True. If you have problems with SWI-Prolog, consider SICStus,
Quintus, YAP, Ciao and (bit further of) GNU. This family is quite
compatible, though each member has its own strengths and weaknesses.
There is a compatibility layer around making life easier if you
want to maintain portability. Of course you can also contact the
community to see whether your problem can be fixed or the system
can already fullfill your requirements in a way you didn't see.

I tried to port the Sudoku solver recently posted and originally developd in
SWI over to VP, but it is not going well. Mostly interested in a
performance comparison. Do you have any data on that?

BTW Jan, I have written rwo sizable discrete event simulations in
SWI-Prolog as I am a doctoral student in Modeling and Simulation. Would
anyone in the SWI-Prolog 'offices' like to know about them?


cheers,
