VIs migrate, like other programs, only if they have the source code. Remove the source code, or diagrams, and you can no longer move the VI between platforms because they can no longer be recompiled on the fly into native code. This happens when you build an executable or select "Save With Options" and explicitly choose to remove the diagrams. What you're asking for seems to be a cross compiler that automatically generates code for all supported systems and builds a "fat binary" that can be executed anywhere. You can't do that AND retain the ability to simply execute a file on each platform, since the executable formats will be different and some native handler application will be required to launch the app. This is in addition to the app quadrupling its size. NI have done it in the same way as pretty much everyone else and that's the way I prefer it. -- Dr. Craig Graham, Software Engineer Advanced Analysis and Integration Limited, UK. http://www.aail.co.uk/
