Programming puzzles: processing lists!

I don't see anything documented about it using NSUB, though, so a subprogram that needs to differentiate its process for specific iterations wouldn't be able to take advantage of that. So I suppose it is more like DOLIST than DOSUBS in that regard.

Would be interesting to compare the performance for a couple of these (where it is a good fit, of course).

The commands are quite different:
DOLIST works with one element from several lists.
DOSUBS works with several elements within the same list
MAP works with a single element of a single list, but fully recursive (goes inside lists of lists and preserves the structure).
