Single-process Run dialog

Procedure

  1. Type the full file path to your application, or browse and select your application.

  2. If required, type the arguments to pass to your program.

  3. Click Run to start your program.

    Note

    If your program has been compiled with Intel ifort, you might not see your code and highlight line when DDT starts. This is because this compiler creates a pseudo MAIN function, above the top level of your code. To fix this you can either open your Source code viewer, add a breakpoint in your code, then play to that breakpoint, or you can use the Step Into function to step into your code.

Next steps

To end your current debugging session select File > End Session. This will close all processes and stop any running code.
