Component Object Model (COM) Client Interface

The COM Engine module allows Nelson to interact with Windows COM (Component Object Model) and ActiveX components.

It enables automation of software applications, access to their methods and properties, and manipulation of COM objects directly from Nelson scripts.

This provides a way to integrate Nelson with a wide range of Windows software, including Microsoft Office applications.
