Can I transfer data in Case structure?
Use a Shift register.
That's the best way to transfer data from one loop iteration to the next.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.
No, only While and For loops have shift registers, but if your Case is not in one of those, it will only run once and the transfered data will never get operated on.
What is it you're trying to do?

If you need it in both cases, you need to generate it outside the case structure, right? 🙂
Else use a shift register to make the data persistent.

Or, if you only want a new array when and every time you hit the OK button, use the shift register to feed the array back to the indicator. (see attached)
It goes back to 0 every time because on the Flase case you are using the "Use Default if Unwired" mode for the array tunnel. Using this mode does not pass what was last passed through the tunnel, but it passes the default value for that data type. So any numeric data will pass zeros, a string will be an empty string, a boolean will be False, a path will be an empty path...

Sorry, I accidentally posted the wrong VI.
Another possibility: If you only want to update the display in the true case and don't need the data in the false case, simply place the indicater inside the true case. 🙂
(And as Ed clearly pointed out, place some wait inside yor while loop so in does not spin millions of times per second doing absolutely nothing except comsume all CPU. ;))
