Hi all,

I have write some more chess code, and I have another question !

Code can be browsed there:
http://scalbert.dyndns.org/adachess/

Inside board.adb there is a procedure:

Move_King(Board: Board_T;
           Color: Color_T;
           Moves_List: in out Moves_List_T;
           From: Position_T) is

Inside this procedure, I have something strange, line 39.

if Col > 1 then -- ERROR should be From.Col
    ...

should be:

if From.Col > 1 then
    ....

I do not understand how this code can compile, because Col is not 
defined there. Perhaps it is because of the way I call it ?

This procedure is called from Generate_All_Moves:
     ...
     when King   => Move_King(Board, Color, Moves_List, (col, row));
     ...

I must have done a big mistake (my fist program in Ada ...), but I do 
not know where. I am sure you will have a good explanation !

Thanks to help me,

Olivier
