How do I set a status flag in a FOR loop?

[emonk]

I have a FOR loop inside of a WHILE loop. If, during any iteration of the FOR loop, a certain condition is true, I'd like to set a flag that would tell the WHILE loop to execute again (after the FOR loop has completed). I've tried a number of CASE and SELECT techniques, but the flag value could change on subsequent iterations of said FOR loop. Should I be looking at shift registers? Local variables? Something else?

Set a shift register initialized to FALSE in the for loop. Then OR the condition with the SR content and write the result to the SR. See picture.

Use a shift register on the For loop initialized to FALSE and OR the
values together. The output of the right shift register on the For loop
is them wired to the continuation terminal of the While loop.

Thanks, guys.

That's certainly more elegant & efficient than the workaround I came up with: (see pic). I'll use it.

Well you could very well use the boolean array but using "OR Array Elements" instead of "Boolean Array to Number"
