Thanks for the reply and the help.
I am using Borland Delphi 7
I am Not sure about classes. (Am new to programming)
I'm a little confused here with some things. I am new to this thank
for your patience.

=46rom this I am stuck as to how I can represent each square to the
user. Do you actually mean instead of having the cells showing 'A1'
just maybe something like this..
_ _ _
|_|_|_|
|_|_|_|
|_|_|_|
|_|_|_|
1 2 3
Displayed? (In order to obtain player input).
>The user only needs to enter a column!
