Module main()
   // Local variables
   Declare Real width, length, area
  
   // Get the rectangle's width and length.
   getRectangleSides(width, length)
 
   // Get the rectangle's area.
   Set area = calcArea(width, length)
   
  // Display the area.
   Display "The rectangle's area is ", area
End Module

// The getRectangleSides module prompts the user for
// a rectangle's width and length. The values are
// stored in the reference parameters.

Module getRectangleSides(Real Ref width, Real Ref length)
   // Get the rectangle's width.
   Display "Enter the rectangle's width."
   Input width
  
   // Get the rectangle's length.
   Display "Enter the rectangle's length."
   Input length
End Module

// The calcArea function accepts a rectangle's
// width and length as arguments, and returns
// the rectangle's area.

Function Real calcArea(Real width, Real length)
   Return width * length
End Function
