Array reference...

[Steve DiStasi]

Is passing an array reference into a VI the equivalent of passing a pointer (instead of passing the whole array)?  Is using references a more efficient style of programming in Labview?

To answer your first question, yes, it is equivalent.

To answer your second question would open a can of worms and I left my can opener at home.

Ahh Matt you stepped right in a pile there.

It should be thought of as a file reference where you are not pointing at the data but pointing at something that knows about that resource.

Updating a FP object using a porperty node "value" is the least efficient way to update an FP object.

Thanks guys,  I guess it's a bit more complicated than saying one way is better than the other.  I applied each method to my application, one at a time, inside a while loop for a large number of iterations. By passing the arrays directly it was a little bit faster.
