cofestand does not return handle to command line

[cocofan]

Sorry if this section is not the most relevant to my question. I'm using cofestand to run coco files from the command line or Octave. However, after running and saving the file successfully by cofestand, it does not return the handle to the host application (e.g., Octave or cmd). Consequently, the next lines of my code cannot be executed and my program gets stuck there. I'd appreciate it if anyone has experienced the same issue or has a workaround for it.
