Enabling Just-in-Time debugging

You can enable Eclipse to be your Just-in-Time (JIT) debug client by configuring the Eclipse preferences. By enabling JIT, Eclipse is invoked when your COBOL program requires a debugger.

There are further preferences that you can configure to control the behavior of Eclipse as it prepares to debug; you can:

(Windows-only) Configure the run-time system to prompt that Eclipse is about to launch as the debugger. This prompt gives you the option to cancel JIT debugging. This requires you to add a DWORD (32-bit) Value entry under Computer\HKEY_CURRENT_USER\Software\Micro Focus\Visual COBOL\<version-num>\COBOL\Config
- disable_cbl_debugbreak with a value of 0 prompts that Eclipse is about to be launched as the JIT debugger, where you can cancel this, if required.
- disable_cbl_debugbreak with a value of 1 disables debugging completely.
If this registry entry is not present, JIT debugging is launched immediately.
Launch the JIT launch configuration preferences prior to debug, enabling you to tweak the debug session.
