This means that if you have nested method calls of the same name, but from different objects, VFP will return to the most recent method of the same name, not necessarily the method associated with a specific object or the appropriate program stack level.

Or if that is an impossibility, is there a way to return to a specific function on the call stack by call stack depth, i.e. return to the 5th function on the call stack via something similar to 'return to 5'. I wonder if the VFP C++ Developers Kit allows a FLL to adjust the call stack pointer (depth) or change the current statement pointer?
