Playing around with for loops today and discovered that while a for will not execute if you feed 0 to the N terminal, the output array will propagate through to a sum operation.
The sum is zero (because the sum of nothing is nothing?) but what does the "#0" error(?) code mean? Is it shorthand for empty array or NULL? Where should I look in the Labview help for documentation on this?
It is saying that you have an empty array (0 elements).
It's the kind of thing you learn by taking the tutorials.
I don't think anyone who has used LabVIEW would know where to find such a specific thing in documentation.
