Perhaps my reading comprehension isn't quite awake yet, but:

1) do you mean the names themselves, or the number of fields (there may
also be a fuu around, in addition to the foo, bar and baz)?

Get the names with tag_names(data), obtain the length with
size(data.(0), /dim), create a base struct with base =
CREATE_STRUCT(...) and replicate() the base to the right size. At least
that is where I would look. Copying is another matter, perhaps others
can comment on how to do this efficiently. At least you have the right
structure to store the stuff.
