: 301 	Turtle gone off the picture
.br
You've jumped too far, or tried to draw a longer line
than there is room for on the picture.
The error message told you the size of the picture - e.g.
if one of the culprits was <function 1 10 1 10> then the
picture goes from 1 to 10 from left to right, and from
1 to 10 from bottom to top.
The first two culprits tell you the X and Y
co-ordinates at the point where the turtle went off the
edge of the picture.
If you need a bigger picture, use e.g. NEWPICTURE(30,30);
Type DISPLAY(); to find how much has been drawn.
The "T" marks the current location of the turtle.
Type the following to print out the location and heading
of the turtle -
 	xposition, yposition, heading =>
.br
The "calling sequence" should tell you which, if any, of your
functions was being executed at the time of the error.
