1. As a result of running...
   

   readProblemParameters
   

   the variables
   

   figureArea and nrSquares
   

   were bound
   
   
2. As a result of running
   

   computeAreaOfOneSquare
   

   The variable
   

   square area
   

   was bound
   
   And so on...

   The ``object'' application architecture solution to the line of squares problem

           double p = los.perimeter ();
