When that happens with the functor name of a predicate, it results in undefined predicates in the Prolog program. It may be nice for a Prolog system to *optionally* flag undefined predicates so that one does not have to trace it all the way to realize it is a typo in the functor name. It has to be optional since undefined predicate may be a deliberate feature to generate failure. Peter Y.F. Wu wup@csv.rpi.edu ...seismo!rpics!wup
