I begin this tutorial a few weeks ago with Part I and received some very nice comments correcting my (fortunately) minor errors. This isn't a tutorial about how to program in a specific language or even really about how to program. I wanted to show the common structure of interpreted programming languages in the hopes of revealing some common threads, rather than focusing on the ins and outs of one language. I've heard it said that if you learn one language, it makes learning the next one easier. My problem is I get lost in the nuances of the language in question and lose track of the basic structure of programming...
