This is a built-in turtle and link variable. It holds a string that is the name of the turtle or link's current shape. You can set this variable to change the shape. New turtles and links have the shape "default" unless the a different shape has been specified using set-default-shape.
Example:
ask turtles [ set shape "wolf" ] ;; assumes you have made a "wolf" ;; shape in NetLogo's Turtle Shapes Editor ask links [ set shape "link 1" ] ;; assumes you have made a "link 1" shape in ;; the Link Shapes Editor
See also set-default-shape, shapes.
