I want to program our Ev3 for FLL (class assignment), and I want to use an object oriented approach in a very procedural environment. Is there a programmatic way to execute another program inside the same project using the augmented LabView? (This is more like using other programs as methods rather than programs, and then calling the "methods" to do a certain task like pull a lever, push a button, move the wheels...)
This is more of a LabView answer than a Mindstorms answer, but you should be able to create a SubVI that represents a task, and then you can place that in the main VI.
