>>Neither of these approaches allows code to be executed purely from within an object's context. With the COMPILE approach, you're creating a standalone PRG. CodeBlock has a special method called SetCallingObject( ), which allows your code to include "THIS." references, which CodeBlock redirects to the object you've passed in.

Actually I was mistaken--that's the way it does work. (It's been too long since I wrote that part.) It simply has an oCaller property that you can set by passing in an object reference. Then your code block cam refer to THIS.oCaller to "escape" out of CodeBlock's own class confines.

Of course creating a PRIVATE variable before calling CodeBlock can accomplish the same purpose.
