pallen,
I am running a nested loop architecture becuase my program is running several pieces of equipment that need to be changed programatically during certain stages of the test. The reason that I am trying to exit the subvi indirectly is in cases where some device in the test was set wrong or the device under test just blew up.
I am trying to avoid displaying the subvi for many reason but mostly because I have up to four loops nested and it would get to be an excess of windows displayed. This would end up covering up the data that the user does need to see in order to know if the test needs to be aborted for some reason, and also causes a lot of windows "blinking" open and close.
Using the abort button is also not an option as I need to exit gracefully in order to shut down test equipment to avoid further damage and save data to see why a problem was generated.
