When you build a LV application, you can configure an option to pass command line arguments to your program. Sorry I don't recall off the top of my head which page it's on, but it is there -- I've used it!
😉Then, you can use the Application property node and choose Application>>Command Line Arguments. You'll get an array of strings from which you can parse your arguments.
