and Devon McCormick responded: > This isn't true. I'm sorry, I used incorrect phraseology. My intent was NOT to state that literals cannot be compared in a Boolean manner (i.e., a series of Boolean values can be generated for the various comparisons). Of course, they can. Rather, what I was thinking, but didn't clearly state, is that I wanted a SINGLE Boolean value (true or false) for the result of the entire comparison, regardless of the lengths of the two literals. (In other languages, I'd be comparing strings for equality or identity--just a simple true/false answer to act upon.) Hope this clarifies!
