It's a variable which the compiler does not put on the stack, it exists just in a register.
Is there a way to make my example work and not have “i” reset each jump by declaring it differently or is that the choice of the compiler?
The compiler chooses this. But you can disable it, I think, by disabling optimizations. Michael.
