So a while loop will be slower than a for loop in any case as LabVIEW needs to do always at least one allocation (and you have to calculate a termination criteria inside the loop somehow too) and at the end one resizing but the performance hit is not that bad. Of course if you can, it is always a good idea to use for loops, even just for the benefit of not having to wire up a termination condition<br><br>Rolf Kalbermatter
