Code Section Editor
You can edit procedure files with conventional text editors, such as NotePad, or with the Progress Procedure Editor. However, the Code Section Editor is the AppBuilder’s main tool for editing structured procedure files. The Code Section Editor is integrated with the AppBuilder, unlike other editors. As a result, when you invoke the Code Section Editor, it displays the appropriate code section, preserving the structure of structured procedure files. The Code Section Editor also preserves the procedure file’s format by presenting only some sections of the file.
To invoke the Code Section Editor, choose the Edit code button or Window
Code Section Editor from the AppBuilder main menu. You can also double-click on an object to invoke the Code Section Editor, if that feature is enabled in the Options Preferences window.
