Is LabVIEW a "pure" dataflow language?

[Aristos Queue]

Oh yea? Well I just got home from the hardware store where I was buying some caulking to plug a hole under my sliding glass door that ants were crawling through

Ah, so we were both looking for better ways to stop bugs. What a coincidence!

I thought that was "deterministic?" How do hygienic functions and deterministic functions differ?

Deterministic puts requirements on the performance of the function, but not on its functionality. A function can be deterministic and hygienic, only hygienic, only deterministic or neither.

For example, in LV Real-Time, I can write a function that reads from a FIFO. I can make that function deterministic, but it will give me back different values every time I call the function because of that FIFO.
