First off, thank you for the great discussion and information. Here is a little summary of what I learned here (and aren't summaries what we all want anyway?).

Using flags in your code (Flag : a variable who's sole purpose in existing is to be checked later on in your script for a particular value.) is just fine with the following caveats:

  1. Try to avoid overuse of flags because it can make your code hard to read and maintain.
  2. Name your flags in a way that indicates what they are measuring.
  3. Never eat yellow snow.
  4. Keep the location where the flag is set and the location where the flag is used close together.

Again, thank you for the clarifications,
