Thank you John! That is a big help. I had not yet stumbled onto the fact that the program that launched the .exe would not wait for it to complete!

I am writing a LabVIEW application that is launched by another system. The system will look at the return code (%ERRORLEVEL% in windows) when the application finishes and will also display anything that comes out on stderr to the user. How do I set the return code from within LabVIEW? How do I write to standard error? I've searched quite a bit but found nothing. Thanks for your help.
