Code change format

Thoughts on how to edit code on a Wiki page, so that the author and frequent readers can see and follow changes.

1. Add a change log before the first command. Include the date, your change, and your initials.

 # 21 Jun 01  Added explanation on "foreach {X Y Z}"  EE

2. Put a question before the code. Most samples have dialogue on the page.

3. At the change, comment out the old, add yours. Reference the date and your initials. Add why.
