Jumps

Direct links flow only downwards. Therefore, if you want to return to an upper step from a lower one, you cannot draw a logical wire from the latter to the former. A special type of block exists, called Jump, which lets you implement such a transition.A Jump block is logically equivalent to a step, as they have to always be separated by a transition. The only effect of a Jump is to activate the step flag of the preceding step and to activate the flag of the step it points to.
