Interlinked Button Control

Does a shift register forward its stored data to the output after each loop, or does it forward the final data once the loop halts?

[Mark_Yedinak]

Any data that is output on a tunnel from a loop will not be available until the loop completes. If you need to pass data out of a loop while it is still executing you have to use a queue, notifier or functional global. Yes, global and local variables will also do the job but I don't recommend their use. There are limited times when they are a valid solution.
