What do you mean by "get" and "transfer"?


If the shift register is not what you want, use a plan tunnel instead.



Typically, programmers are interested in the first, not last, error.


Can you show us your code so we have a better idea what you are trying to?

If you stop the while loop with an error condition, the first error should be automatically the last error 😉


And this is basically the best question Christian arises: why do you want to proceed with the loop even though there already is an error, but are interested in the LAST error instead of the FIRST error?
