Visual Debug is an integration between the IBM Developer for z/OS Debugger and the Program Control Flow view. 

It provides a graphical view of the COBOL and PL/1 program execution flow to help you visualize the program structure and the relationships that exists between the different paragraphs and sections, it helps you identify where you are in the program, as well as the current execution path.

Visual debug is available with IBM Developer for z/OS, IBM Developer for z/OS Enterprise Edition, and IBM Wazi Developer for Eclipse, a component of IBM Wazi Developer for Red Hat CodeReady Workspaces.

In this video, using a COBOL debug session, we will demonstrate how to enable visual debugging, visualize the stack trace, set a paragraph entry breakpoint and use stack pattern breakpoints.
