Fscommand(exec)

Does anyone know how to get fscommand(‘exec’ ‘Test.app’); to work? I’m on a Mac and I can’t seem to launch a little test script from flash. (as3 fl9). I’ve looked everywhere and can’t seem to find to much but dead ends. Seems like there’s gotta be a way to allow mac flash projector’s execute outside files in as3.

Thanks,
Ryan
