Hi Gregory, It is generally a good idea to return results via queues, because it is very flexible, but I don't quite understand why you can't return results via variables in the RPC goal -- instantiating `output' variables in your RPC goal is probably the easiest way you can return simple results. These variables are anonymous variables when you call the RPC, because they should be uninstantiated, and are simply `placeholders', hence the null value. The RPC returns a new CompoundTerm representing the RPC goal after the execution, i.e. the anonymous variable(s) when you called the goal should now be substituted by the results you want to return.
