every value subtract of last value

I gave up.  It was obvious that he was not capable of figuring out the simple solution based on my description.  I'm not sure whether this would be homework, but if it is, it is so simple that it can't be worth much.

Hopefully this will clue him in and give him a jump start.  Without taking the time to do the tutorials, he won't get very far beyond this.

That's why it is  important to take the tutorials.  Get a basic knowledge of LabVIEW.  Then when you are stuck, log on and ask questions.

Everyone starts somewhere.  Just be sure you actually understand how Raven's Fan's code works.  Open a new VI and reproduce it without looking at the original, add new shift registers, see how you can easily make an array of ALL the values coming out of the loop by auto-indexing.  LabVIEW has many great tricks that are easy to learn.  Go through the tutorials and play around.  Just remember that LabVIEW is like every other programming language, although it has the tools to create amazing code, it's up to you as the programmer to use those tools wisely and efficiently.  LabVIEW makes it very tempting to just start dropping blocks and wires down without taking time to plan thing out (the Code & Fix Paradigm) but it's always better to spend a few minutes planning what you want to do and choosing the right tools to do it.  Trust me on this, I'm still supporting a ton of code that was rushed through instead of thought through and it sucks.
