In the Blue Clay Intro (Part 2) task that you just completed you have learned how to write a Blue Clay Command.

In particular, you learned to defined a command in a top-down manner, which simply means working from higher-level commands to lower-level commands. First you defined cycle, then its three subordinate programs.

Here is something to think about. The program featured in this activity,cycle, was defined in a top-down fashion. Yet it was tested in a bottom-up fashion. It turns out that the approach to program development characterized by top-down definition and bottom-up testing is very popular. Any ideas why?

When you get tired of thinking about this, please return to the Colored Clay Languages page.
