This is off topic, so-to-say, but computer languages can be esoteric: It's the 150 anniversay of L. Carroll's "Alice's Adventures in Wonderland." May I dare say most people, including myself here(I studied languages like BASIC, COBOL & PL/C, know very little about the programming languages that make old & new computers do what we wish looking backwards? Logic, like "Alice's...", can elude us at any time... Happy computing. Murray :)
