I suspect that most CIF developers want to keep nesting > fairly shallow, given that CIF disallows and STAR loop nesting. Is it necessary to apply a restriction to the recursive depth? As you say humans will keep it fairly shallow anyway to keep things clear, but I can foresee a machine generated data value being quite deep. If I was to output as a CIF2 value (not that I would ever do this) the entire internal representation of a domain dictionary category (and its attributes), including methods and data file values, it would be a deeply recursive compound data structure of significant complexity. But it would all fit in a Table. cheers Nick -------------------------------- Associate Professor N.
