Hi Geoff.

>I am trying to figure out how the IMPLEMENTS clause works and how to use it.

The IMPLEMENTS clause provides a way for a VFP class to implement a COM interface defined in a DLL or EXE. The easiest way to set it up is to open the DLL in the VFP Object Browser, navigate to the interface you want to implement, and drag it to a code window (such as a PRG). The Object Browser will automatically generate the correct code for you.
