The point is not the designing structure problem. We develop program using structure programming technique and develop it for very large scale database comparing to many companies. For example, Image management system for credit card for 3 of 5 biggest Thai Bank. Absolutely, we also use other developing tools, such as Motor Insurance by AS 400 and MS SQL Server for Client Server environment. In fact, I want to say that if we have well design, FoxPro can do many thing for us.
The idea of patch file is good. However, I think it should be suitable for package program because you have to make an analyze program for this purpose. However, it is a nice idea. Thank you.
