Turtle state values (can plug into a parameter)

Turtle state values (can plug into a parameter):

**X, Y, ~~heading~~ (Zeros for each are center screen, pointed up. Heading is degrees clockwise.)

* X, Y, Heading (Zeros for each are center screen, pointed up. Heading is degrees clockwise.)

**angles are degrees from 0 to 360 (for larger values and smaller values all multiples of 360 are subtracted or added to get the value into the range 0..360).

* angles are degrees from 0 to 360 (for larger values and smaller values all multiples of 360 are subtracted or added to get the value into the range 0..360).

** Example: 90 means a right angle clockwise, –30 means a 30 degree angle counterclockwise

::Example: 90 means a right angle clockwise, –30 means a 30 degree angle counterclockwise
