Fencing in a Turtle

["Gail Garthwait" <abigail@xxxxxxxxxxxxxx>]

Thank you for sending the directions about how to draw with the turtle by 
clicking and dragging the turtle!!   Now the student wants to know how to keep 
the turtle from going too far.  I can't see any solution but I wondered if 
anyone out there in
MW land can?

==============If you try out the attached sample,
1) click the start/stop button and click on the turtle to show the ink
2) try sending the turtle to the very far left, or very far right, or way up 
or down while he's drawing, and it makes a heck of a mess.

How can I keep my turtle from going too far in any direction, especially when 
the turtle is being controlled by a user, without messing up the program and 
its purpose?

If it's possible, I would like my turtle to stay in the following area:

-360 < xcor < +360
-200 < ycor < +200

Any ideas?
