Viewing the Program Structure chart

A Program Structure chart provides a visual and interactive presentation of a program as a collection of procedures or paragraph nodes. You can expand and collapse nodes to assist in your code analysis. You can view the program and the Program Structure chart side by side.

You can use the Program Structure chart to perform the following actions:

  • Zoom in and zoom out the chart.
  • Move the visible area of a large chart without changing the zoom level.
  • View details of procedures, callable programs, and database nodes.
  • Show and hide icons in the nodes, external calls, and zoom slider
  • Identify dead code in the program.
  • Navigate between the chart and code in the editor.
