Baldness is not a problem, however, slowing the onset of dementia is the aim of this project.

OK, so I'll go back to my original idea and use edit boxes. A grid of 9 x 9 edit boxes does actually work and it makes it easy to keep track of the digits. The first digit is [0,0], the first digit on the second line is [1,0] etc. Nine 3 x 3 boxes could add some complication to digit tracking.

I did actually get my canvas version to the point where I could enter digits into the cells but I had to enter them in sequence so that the logic part of the program knew where the digits were. It was all becoming somewhat complicated.

Thank you for the table example. I'm not sure what "tab = DisplayTable" does at the moment, I'll have to run it to find out.

Thank you for your detailed answer, more food for though.
