Release 10.1A: OpenEdge Development:
Debugging and Troubleshooting

Using System Handles for Debugging

The DEBUGGER system handle provides attributes and methods that allow you to initialize, start, and control a debugging session from the 4GL. It is intended for experienced Progress programmers who want to:

Control breakpoints at specific points in their code, regardless of how the surrounding code is modified, or set breakpoints in include files that might appear in many different procedures.
Develop their own OpenEdge development tools, and initialize and control Debugger interaction from those tools. For example, the OpenEdge Application Development Environment (ADE) uses the DEBUGGER system handle to invoke and manage the Debugger from ADE tools such as the Procedure Editor and ADE Desktop.
Debug AppServer and WebSpeed applications.

The SESSION system handle allows you to specify whether you want alert boxes to include a Help button that provides access to a Stack Trace dialog box and the Debugger.

This chapter contains the following sections:
