And please do not talk about why labels are bad, or why I should not be using them.
Why not? I've been programming in C and C++ for 30 years, with 100s of 1000s of lines of code, and not a single goto in any of that. The number of legitimate uses of goto in the whole lot of C code can probably be counted on one hand. Maybe two. I seriously doubt that anything you are doing on the Arduino NEEDS goto.
