>So how does it accomplish parallel processing (in a nutshell) with fox? Is it using threads at all? Is it using dlls?? Thx

It creates workers in separate processes, and sends commands to those workers to run your code. Threads vs. processes is actually only a small part of the equation. Using separate processes does have more overhead, but it allows us to use the full functionality of VFP in the workers, including running reports. Later down the road, I might add support for threads/MTDLL, but that will require some C++ programming (similar to MTmyVFP), and that's not my area of expertise. More info in the videos.
