Saves a copy of the VI that is readable by LabVIEW version 8.0 and later. If you save a password-protected VI for a previous LabVIEW version, you must enter the password. You can enter the password programmatically as an input on the Open VI Reference function.
This method is similar to the LabVIEW Version option on the Save for Previous Version dialog box.
