| ## VisualAge COBOL Application Understanding

Get a handle on the applications that you identified as having date impacts from your earlier assessments and analysis by using the VisualAge COBOL, Enterprise development environment for analyzing and maintaining legacy COBOL programs and applications. You have identified your date-impacted applications during Inventory and Assessment; now drill into the impacted applications and understand the impacts within each one.

The power of VisualAge COBOL enables you to fully leverage existing COBOL resources in a client/server environment, taking advantage of distributed processing. If your application is host based, you still have the ease of use and convenience of the workstation at your disposal. VisualAge COBOL reaches out to you, as it were, bringing your host applications to the workstation for you.

Check out other tabs in the Information Notebook for more information on developing applications with VisualAge COBOL.

Capture and study the key information regarding your applications with Application Understanding (AU), which helps you understand your MVS batch jobs: how they are constructed, the interdependence of their components, where they are used, and what files they process. AU scans your host JCL and extracts this data, then downloads it to the workstation where it provides graphical displays of this analytical data. Use these displays to identify the components of a job, the relationships among them, and the resources they share.
