Thanks for that. I am *sure* that I had problems with lists (say "xxx") that had entries "ylengths" and (later) "y". I got into trouble when I did xxx$y. This produced the value of xxx[["ylengths"]], not of xxx[["y"]], which of course caused chaos. Now xxx$y produces xxx[["y"]] as desired. But you say that nothing has changed! The only explanation that I can think of is that the Universe (including its past) has changed, while I wasn't looking. That seems to keep happening to me! :-) (Cf.
