>I would ilke to execute another application (not using the RUN command) from withing Visual FoxPro. Is there an API, or something, that will do that for me? My EXE needs another program running to work and I want to make sure it is running simultaneously.

If you don't need to wait for the program to finish running, you can just use shellExecute to do this:

DECLARE Long ShellExecute IN Shell32.dll Long, String, String, String, String, Long
?ShellExecute(0,"open","c:\myprogram.exe","","",0)
