Tomasz,
No problem. Call the new variable what you like.
In my opinion, this one feature will get AB closer to the
functionality of a 'Software Development Platform' for non-programmers
in the sense that User can generate easy one-pass statistical
calculations for entire databases or watchlists or whatever.
This feature would significantly speed up the process of analyzing
different aspects of technical market behavior.
Regards,
Phsst
