>We are currently running a FoxPro application that has a call embedded in it to call another FoxPro application. Has anyone ever done this before? What is the best way to hault the first application while the second one is being called? And how does the first one know when the second one has closed?

If you just wanna run the EXE, look in the Files section for Ed Rauh's API_RUN or somethign like that. It has a method called "LaunchAppAndWait" that might be able to do what you want.
