Implemented, thanks.

The other comment I'd make is to start thinking about how you'd _test_
your program automatically.

You are right, I should. But I am fighting with myself on this topic. I have been fighting myself for some time. As it seems the test slow me down. I am sure latter they may speed me up, but then again I am still a relatively new programmer and so my code is very fluid to the situation at hand, so tests for immature code seems like a bad idea. Still you are right.


Now I am having problem implementing a way to drop the zero values to the bottom of the grid. I need to look at more of the column at once possibly all of it, or remember where I was dropping. This is my latest code any help would be appreciated.
