Glad it helped.

No, I don't have one. But it's pretty straightforward to write one, the
Numeric C API provides functions to create arrays from existing data. You'll
be surprised how conceptually similar Blitz and Numeric turn out to be (which
is a good thing).

As I said, so far I've been able to bypass this issue by creating my arrays in
python and 'filling' them in blitz. But this is not always a realistic
possibility, so you may indeed have to learn the reference counting management
