Hi, Neil.

POGO technology enables the compiler to instrument an application and collect information on how the application is used at runtime. This information enables Visual C++ to further optimize generated code based on real-world application usage patterns."

It would be nice, but I don't think this kind of technology doesn't apply to VFP. This is a trick you can do on a very low-level compiler. VFP compiler just generates p-code that is later interpreted by the runtime. I don't think there is too much room for p-code optimization.

For an interpreter, VFP is already quite fast, anyway.

See you,
