pseudocode?

pseudocode is a good start, on the way to real code. but if you wanna talk about pseudocode, hurry up, because i'll soon deliver cost-free _working_code_... which trumps pseudocode. but if your pseudocode morphs into code that runs, does the job acceptably well, and is both cost-free _and_ open-source, then you will have trumped me. pseudocode rarely makes that journey, though... still a worthwhile and entertaining exercise, however. -bowerbird
