Some technologies behave differently in
Visual COBOL and this might affect how you upgrade existing applications.
COM Interop The tools to help create COM objects are not supplied with Visual COBOL. However, the COM run-time components are supplied, so that COM is supported and your applications can interoperate with existing COM objects.
File Handling The way you integrate your own security modules into Fileshare has changed. Also, the FILEMAXSIZE setting is different for Visual COBOL and for Net Express and Server Express.

Test Coverage Code coverage for native COBOL applications available from within the IDE in Visual COBOL integrates the Test Coverage functionality.
