Hi, I have vi that uses shift register to modify a value with each iteration of the WHILE loop. However, I do not want the value to be modified on every iteration. There are some cases where I want the value in the shift register to remain fixed as the other operations in the WHILE loop execute during subsequent iterations of the WHILE, and, then, at some time later, I want the value in the shift register to resume being modified. For example, in the attached sample code, a value of "2" is added on each iteration of the WHILE loop. Also, at each iteration, the LOOPER value is multiplied by 10. Suppose I want the shift register to increment by 2 only if the INPUT is greater than 1000, and the INPUT is known to fluctuate above and below 1000. When the INPUT boolean is TRUE, I want the shift register to increment by 2, but, if it is FALSE, I want the other function in the WHILE loop to continue executing, but, I want the SHIFT register to hold the last value and act on the last value when the boolean becomes true again. For example, if the boolean is true we would see these values in the SHIFTER and LOOPER indicators, respectively: 2, 10 4, 20 6, 30 8, 40...etc. If the boolean is true, false for 3 iterations, and then becomes true again, I WANT to see something like this... 2, 10 4, 20, 6, 30 8, 40 , 50 , 60 , 70 10, 80 12, 90 14, 100 Is it possible to pause (and resume) the incrementing of the shift register, without interrupting the execution of the other functions in the WHILE loop? I tried with a case structure, but,... couldn't figure out a way to put it together. Thanks,

Your most recent was in LabVIEW 2013. Have you tried the suggestions of how to solve the original question?

Yes, got it, thank you. I figured out the case structure approach, and it appears to work.
