Before we jump into the fray with gusto and abandon (and aplomb, of course), I was recently chatting with my chum Steve Manley who features so prominently in my main Cool Beans column. I'm not sure how we got into this particular topic, but Steve taught me a very cunning coding trick as follows... It very often happens in my programs that I have an integer variable that I use as a pointer (or index) to a number of elements in an array or some such entity. For example, let's say we have ten elements of something or other numbered from 0 to 9. For clarity in our code and to make it easy to modify in the future, we might define NUM_E ('number of elements') as being 10 and MAX_E ('maximum element') as being 9. (We could also define MIN_E as being 0, but we typically just use 0.)
