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 
details.

Best,
