Gil, I appreciate what you said. In the perfect world ( wasn't that a Blondie song), the API calls, linkage between languages would be well documented and extensive samples. But life and code and development sometimes are messy, so experimentation is necessary. I ask questions, because like many of my colleagues I don't have all the answers, especially when I looking at a new design or concept. Times have changed no more PLMs or source to look at ...so here we are...
