(open in window)[00:00] The end step is used to indicate that the chart is finished executing. You can find the end step on the pallet here at the end. And, to use it, you simply drop it on the chart. And, if this chart were to execute, and reach this end step, the chart would then stop. A chart may have any number of end steps on it. So, for example, here's a chart that has two different end steps. You can also have no end step at all. Here's a chart that never ends, it will just loop forever, unless somebody cancels it. End steps are not allowed inside of parallel sections. If you try to put an end step inside of a parallel section, you can see that it creates a compilation error, and you won't even be able to start this chart. When chart reaches any of the end steps that are on the chart, the chart enters the stopping state. This is when the chart's on stop event script will run.
