  50.                         <H2>Functional Overview</H2>
  51.                         The Fun 'n' Games page provides a very simple word search game. First the square is generated by a server-side
  52.                         Java component and displayed. The user can then select cities. Once the user has selected a city 
  53.                         at the bottom of the screen, the user is prompted to enter the X and Y coordinates of the hidden word in the matrix.
  54.                         The prompt is dislpayed using Dynamic HTML (DHTML). 
  55.                         <P>
  56.                         The game finishes when all the cities are correctly identified.
  57.                         <P>
  58.                         <H2>Components Used</H2>
  59.                         A Java component called <STRONG>Hidden.Words</STRONG> generates the matrix of letters and cities. 
  60.                         The component is made from three classes: <STRONG>HiddenWords</STRONG>, <STRONG>SquareElement</STRONG> 
  61.                         and <STRONG>ChosenWord</STRONG>.

  108.                                     This method builds a random square of letters and then populates it with a random series of non-duplicate cities.
  109.                                     The words can go either across or down. Once it is populated, an HTML table is built inside the component and passed back
  110.                                     to the calling page, FunNGames.asp, through the ASP <STRONG>IResponse</STRONG> interface. 
  111.                                     To make this easier, extensive use of the ASP Java Component Framework is used.
