hey I don't want to start a big 'numbers vs letters' controvosy here! whatever nomination you prefer, floats my boat.

the fact is that when I started making these puzzles, the formulas in the cells would also include actual numbers, and not just references elsewhere. eg - a formula could be AGx5, or 3-BL. I thought in that case, it was best to keep the numbers (as numbers) and the letters (as identifiers) separate. sinc then, I've eliminated the bare numbers and moved on to an all-reference puzzle.

so, we could call them dogs and elephants for all I care. but I agree that numbers for columns and letters for rows is a more 'conventional' notation, so OK. let's use that.
