Functions vs. Methods

   The function to move a turtle forward:

      Turtle t1 = ....

      forward ( t1, 50 )

  The same operation written as a method:

     Turtle t1 = ....

     t1.forward ( 50 )

There are no Turtle Functions for Color Manipulation

  In order to change the pen color for a turtle

    t1.setColorPen ( red )


Potential Useful Turtle methods

    t1.getPenColor ( )
    t1.setPenColor ( <color> )

    t1.getPenWidth ( )
    t1.setPenWidth ( <int> )


The use and creation of Functions

   A Function Call:

       <functionName> (  <parameter_values> )


 The actual Function Code

   <functionName> ( <parameter_variables> ) :
     <statement1>
     <statement2>
     ...
     <statementN>
