To enable just-in-time debugging

Restriction: This topic applies to native COBOL only.
  1. Click Tools > Options > Debugging > Just-In-Time.
  2. Check Micro Focus Native Debugger.
  • You can also enable just-in-time debugging using the debug_on_error runtime tunable. See the debug_on_error reference topic for details.
  • It is not possible to enable both Just-In-Time Debugging and Core Dump concurrently.
  • For 32-bit applications, when your application fails, the COBOL debugger is invoked if it is not already running.
  • For 64-bit applications, Visual COBOL must be running and waiting for a debuggable attachment.
  • If you have the source files and the .idy (program symbols) files, the source code is displayed at the line where the error occurred. If you do not have the required files, you are given the name of the source file or program where the error occurred.
