LOGO for DOS 
by Larry Kheriaty

This is a simplified version of the LOGO language designed especially for 
teaching young people about programming.  It was used for over 8 years at 
Assumption (K-8) school in Bellingham, WA, to permit 4th grade students to 
learn about text editing and programming.  To program LOGO, you use simple
commands like "FORWARD 10" or "RIGHT 90" to tell the turtle how to move
on the screen.  Meanwhile, the turtle draws a line as it moves.  It's
very easy to create programs to draw all kinds of pictures.  In the process,
the student learns how to use a simple word-processor to write the LOGO
programs, and can even use the word processor to print formatted documents.

This version of LOGO has all the turtle graphics capabilities but none of the 
LISP-like string manipulation features.  It contains a simple text editor used 
for writing LOGO programs or text documents.  From the text editor the student 
moves to turtle mode by pressing F9.  From there the student enters individual 
Logo commands, or runs the Logo procedures entered in the editor mode.  The 
student returns to editor mode by pressing F9 again.

To install it, unzip all files into a directory, which you might name \LOGO.
A file named SAMPLES contains a set of sample LOGO procedures. To run it: 
   CD \LOGO
   LOGO SAMPLES
This displays the sample file in the editor mode.  Use the scrolling keys to 
view these procedures.  It may be helpful to print a copy of the SAMPLES.  
Within the text are instructions for running each sample.
Press F9 when you are ready to run them in turtle mode.  Then type commands.
For example, you might type "SPIRAL 10 15".

The manual is supplied in LOGO file format. It is in 3 files: LOGO1.DOC,
LOGO2.DOC and LOGO3.DOC.  To print any of the manual sections, use LOGO:
   CD \LOGO
   LOGO LOGO1.DOC
Then press F8 to print.
