I thought all variables declared inside a function (like below) were “on the stack” and I don’t even know what a register variable is honestly. 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?

procedure TCoroutine.Start;
	i: integer = 0;
