Which of the following commands is not available in the OutSystems debugger?

The command "Restart Debugging" is not available in the OutSystems debugger. This is because the debugging environment focuses on other functionalities that allow developers to control the flow of execution for diagnosing and fixing issues in their applications. The debugger provides options to stop, continue, and step over code execution, enabling a more granulated observation of application behavior.

In the context of available debugging commands, "Stop Debugging" is essential for halting the debugging session, "Continue Request" allows the execution to proceed after a breakpoint, and "Step Over" lets developers execute the current line of code and pause at the next one without diving into any function calls. Since "Restart Debugging" does not facilitate the step-by-step analysis that's critical during debugging sessions in OutSystems, it is not part of the toolset.
