Hi Warren,
The examples in the supportline web site will not help you understand OO concepts of Visual COBOL. These are mostly examples for older products like Net Express and Server Express that have not been updated in quite some time.
The examples that you should look at are in the product that you already have. If you go to the Windows Start menu and look in the Visual COBOL product group you will see a link for Samples. This will open up the samples browser and allow you to scroll through a list of samples that you can then open up in the product. If you choose that managed code category you will see that examples for .NET specifics. Look at the Core .NET example for instance.
There is also a getting started manual for OO programming and a set of videos that we did on the subject.
The manual can be found from a link provided in the documentation in the section for Managed Code programming here:
The OO COBOL Webinar Series can be found here:
Thanks
