Clear shift register before running VI again

[LCI_RnD]

That works, but you will have to manually clear it every time. If you initialize the shift register with a blank array, it will automatically clear when you start the program

Hi LCI_RnD, I did not have to manually clear using this method. Kinda odd, but it clears the constant and sets is to 0 always. But thank you for your idea.

You can also place the append function into a case structure and bypass it when the iteration terminal is zero.
