I. Description

This program generates the Dragon Curve Fractal through user-inputted
iteration amounts. If you've ever read Jurassic Park, you'll know what
the Dragon Curve is (it's the pictures at the beginning of each
chapter).

II. Installation

Send the file Dragon.8xg to your TI-83+ calculator. Ungroup it and you
are set to start drawing the Dragon Curve.

III. Directions

First, run the program dragon on your calc. You will be prompted for
the number of iterartions that you want the program to draw. Press
enter and the program will start generating a code to draw the pic.
Once it's finished, it will draw the fractal.

It's important to note that if you pick 5 or more iterations, the
program will take a long time generating the code.

While drawing the fractal, the calc might come up with an error:memory.
This happens because the calc's variables are overloaded. This isn't
anything to worry about. At the error prompt, press quit, and then run
the program drawz. This will continue drawing the fractal. Continue
running drawz every time you get an error message until the fractal is
done drawing. It's important to run drawz immediately after you get the
error message because variables necessary to draw the fractal could be
overwritten if you do anything else.

I've included a pre-generated code with the group in String 1. It
includes code enough for 10 iterations. To use this string instead of 
generating your own, just run the program draw, and it will use that 
string (Remember that you still have to use the drawz program when 
you get an error message). This string is included for your benefit,
because it will take a long time to generate codes above 5 iterations.

Eventually, the fractal will get too big for the display (if you've 
done 7 or more iterations). When this happens, you'll get an 
error:domain message. The program is unable to draw any more. 
Press quit and you can save the picture.
