I don't know what "factor common sub-statemnts" means.

In several of these exercises I have, in fact, re-worked code, but I'm not ready for any extensive re-working.

Your last suggestion about using "readmore" is certainly worth considering for some posts. I understand what you're saying. But I'm still at the early learning stage, and posting this longer, non-executable code block allowed me to present a specific problem. When I've learned more, I hope I will be able to follow your suggestion.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
