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.
Dialog System Support for Dialog System applications is available in Visual COBOL for Visual Studio if you install the Compatibility AddPack for Visual COBOL, distributed for free through the Micro Focus SupportLine Web site, and the Product Updates section.
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.
Test Coverage Code coverage for native COBOL applications available from within the IDE in Visual COBOL integrates the Test Coverage functionality.
