Re: Zero divides?

[verschel@xxxxxxxxxxxxxxxxxxxxx (Mark A. Verschell)]

Just a guess, but 0 would be a valid value, and 1/0 would be flagged as a BAD or
MISSING value, so it would "hold" a place in the grid open, but wouldn't be
included in the vertical section that the user is trying to generate.

I am sure that Steve Hanking will correct me if I am wrong :)
