GRAPHICS
========

The center of the graphics window is turtle location [0 0].  Positive
X is to the right; positive Y is up.  Headings (angles) are measured
in degrees clockwise from the positive Y axis.  (This differs from the
common mathematical convention of measuring angles counterclockwise
from the positive X axis.)  The turtle is represented as an isoceles
triangle; the actual turtle position is at the midpoint of the base
(the short side).


TURTLE MOTION QUERIES
---------------------

POS

outputs the turtle's current position, as a list of two numbers, the X and Y coordinates.


HEADING

outputs a number, the turtle's heading in degrees.


CONTROL STRUCTURES
==================

WAIT time

command. Delays further execution for time 60ths of a second. Also causes any buffered characters destined for the terminal to be printed immediately. WAIT 0 can be used to achieve this buffer flushing without actually waiting.


WORKSPACE MANAGEMENT
====================


WORKSPACE CONTROL
-----------------

SAVEL contentslist filename

command. Saves the definitions of the procedures, variables, and property lists specified by contentslist to the file named filename.

        Example:  SAVEL "INITIALS "W:/INITIALS.TXT


SETEDITOR path

command. Tells Logo to use the specified program as its editor instead of the default editor. The format of a path depends on your operating system.

	Example:  SETEDITOR "C:/WINNT/NOTEPAD.EXE
