This should be simple, but I'm not getting it today.... I'm doing processing on large MP3s using DOS command-line applications. I want to run each as DOS command, using Run instead of RunWait because as soon as the process exists, I want to immediately change the priority of the process to idle so it doesn't hog the processor. After the priority is set, however, I'd like to wait until the process completes, but report the DOS exit code. Run returns the PID instead of the errorcode like RunWai
