This can result in some functionality being described in the topspfed together with code snippets where that functionality is not in the specific product being used.

This problem is evidenced at the “Tutorial” and “Sample Application” level as well. That’s not to say that they can’t do COM programming right now, as a number of Clarion users have written articles and code that allows you to access COM components from Clarion.
