Programming: flow control
At this point, you probably understand that the Arno (and other computers) run through lines of code one at a time. This won't take you very far unless you can control the flow of the program. For example, you may want to execute certain lines of code under one condition and other lines under a different condition. Since the Arno is designed to interact with the real world, you often need to control the timing of events by getting the Arno to stop and wait. We cover these topics in this section. Specifically:
