For example: Same as no viable alternative, but it is known what should be at that So we cannot use this function conditionally. This gives us a general idea of the values being used in each loop iteration: We can also extract multiple values from loop iterations by building a single string which we will display using a label after the loop executes: When loops with numerous iterations make displaying all their values impractical, you can sample a subset of the iterations. // Method #2: Plot a character in the bottom region of the display.
