It's been a while since I played with Cobal is there a cobal for windows that 
is not ridiculously expensive.  If there is I might
give it a shot.

Hi Sina,
I bet he didn't do it in Cobol.

Oh my god, and he's written it in like 10 other languages too.
 
Do you know how sick I was of hearing about Yahtzee! Lol
 
But it's so addictive!

I could also give you some really good guide lines on the game of Yahtzee since 
I have actually wrote it for Windows mobile and
Windows  and it runs on both with the same executable which was a pretty cool 
thing to pull off using c#   It also had an OOP die
that was used in an OOP dice box and the scorecard and stuff was all laid out 
in an object oriented way.  I had thought of using it
to do a class in OOP in fact that is why I was asking about the book stuff on 
NDN.

I agree with this. I think a card game, of which there are thousands, might be 
the best because it lets you have some of that chess
like feel in that you still have to solve representation problems. The game of 
life or monopoly would do the same thing to, but the
boards are a bit more complicated so folks tend to abstract them out into Rules 
classes.
 
Poker is probably one of the simplest after you pass things like 21/blackjack 
and so on.
 
Take care,

Jim,
 
I want to make a small suggestion.  Your starting out with a very difficult 
problem to use OOPO to solve.  The truth is there are a
lot of ways you can do this for a chess game and none of them are really that 
good.   The problem is chess is really just  search
tree and a state machine and making objects out of nouns and methods out of 
actions will not make the best of the chess games.  If
you're looking to learn OOP I would suggest a game like Monopoly or Life where 
you can actually have Objects work as they should for
example you could have players on Monopoly, locations that have descriptions, 
prices, and things of the sort.  Maybe start with a
card game where you can have objects that deal with decks of cards and players 
and score cards and things of the sort.    It's
really up to you but Chess gets too complicated to fast and then you're not 
really thinking OOP your trying to decide the best
method of figuring out who is winning which is a tougher problem then you might 
think.

Hi,
If it's OK, I'd like to take this a little further. I was thinking about my  
little chess move validation project. I thought I would
sit down and try to write out a little plan, because my book says that the 
nouns become objects, but I started to get confused when
I asked myself this question. Do the pieces move, do the squares on the board 
somehow get pieces, or does some controller in the sky
move the pieces? In the real world, the controller would be the player who is 
moving the pieces. The pieces can't move them selves,
and all the board can do is sit there and have pieces on its squares. The rules 
would be another object, would they not? Oh my head.

Hi,
I found this humorous.
 
Understanding the Parts of VBA "Speech"
 
If you were going to play soccer using BASIC, the instruction to kick a ball 
would look something like
 
"Kick the Ball"
 
Hey-this is how we talk! It makes sense. You have a verb (kick) and then a noun 
(the ball). In the BASIC code in the preceding
section, you have a verb
(print) and a noun (an asterisk). Life is good.
 
Here is the problem. VBA doesn't work like this. No object-oriented language 
works like this. In an object-oriented language, the
objects (the nouns) are
most important (hence, the name: object oriented). If you are going to play 
soccer with VBA, the basic structure would be:
 
Ball.Kick
 
You have a noun-the ball. It comes first. In VBA, this is an object
. Then you have the verb-to kick. It comes next. In VBA, this is a method.
 
The basic structure of VBA is a bunch of lines of code where you have
 
Object.Method
 
Sorry, this is not English. If you took a romance language in high school, you 
will remember that they used a "noun adjective"
construct, but I don't know
anyone who speaks in "noun verb" when telling someone to do something. Do you 
talk like this?
 
Water.Drink
Food.Eat
Girl.Kiss
 
Of course not. That is why VBA is so confusing to someone who previously 
stepped foot in a procedural programming class.
 
Let's carry the analogy on a bit. Imagine you walk onto a grassy field and 
there are five balls in front of you. There is a soccer
ball, a basketball, a
baseball, a bowling ball, and a tennis ball. You want to instruct the kid on 
your soccer team to
 
Kick the soccer ball
 
If you tell him kick the ball (or ball.kick
), you really aren't sure which one he will kick. Maybe he will kick the one 
closest to him. This could be a real problem if he is
standing in front of
the bowling ball.
