Can you add how many "trues" have ocurred?

Question

I have a vi that generates a "pass" of "fail" indication of a measurement. Can I incrementally add how many times "true" or "false" has been generated? I have the vi in a 'while' loop but I don't exit it until I shut the program down and the rest is in a flat sequence structure.

OK, place the shift register in the outer while loop, there is no need to have the inner loops.  (see image below)
Use the array method and initialize the shift register with a 3-element I32 array outside the big loop. Now you don't even need the "first run?" primitive.
Delete the two "toEXT", they make no sense at all!
Keep the representations consistent (e.g. you convert DBL to EXT, then use a SGL indicator!)
Replace the case structure with an event structure and place the bulk of your code in it. Make the event "take a meaurement: value change". Rremove all waits, they are no longer needed.
Add an empty event for "stop: value change" containing only the stop terminal wired to the loop condition.
Note that if you expect to count more than 2^16 counts, you should convert to I32 after the "boolean to 0,1" or you'll overflow. If you can guarantee that the counts wil remain below that, you can leave the "to I32" out and initialize the array with U16.
Your sequence structure has no purpose, delete it! There is no reason to delay the analysis by 1000ms.
