I've heard some chilling things about Turbo Prolog. Such as

1) The programmer must not only declare each predicate, but also whether
each parameter to the predicate (not correct terminology) is input
or output. This means you can't write relational predicates like
grandfather.

2) The backtracking is not standard.

3) "You can do any thing in Turbo Prolog that you can do in Turbo Pascal"

I want to hear from the LP community on Turbo Prolog as to it's ultimate
merit.  Something beyond the dismissive flames.  

Thanks in advance,

Jan
