These are the most important definitions:

   Number_Of_Columns : constant := 7;
   First_Column : constant := 1;
   First_Row : constant := 1;
   Winning_Move : constant := 4;
   Nil_Move : constant := 0;

   type Player_Type is (Nobody, Human, Computer);
   type Board_Type is private;

   subtype Move_Range is Natural range Nil_Move .. Number_Of_Columns;
   type Valid_Move_Range is range First_Column .. Number_Of_Columns;
   subtype Column_Range is Valid_Move_Range;
   subtype Row_Range is Valid_Move_Range;

   type Moves is new Move_Range;
   type Columns is new Column_Range;
   type Rows is new Row_Range;

Some of these could have been done differently in Ada2012 (but the code dates from 95 days).
