Mandelbrot Plotter
by Nick Smith

This program plots the Mandelbrot set, or a selected part of it. When run,
the program draws the base Mandelbrot. Select and Adjust change the size of
a white square which can be positioned with the mouse. Clicking Menu will
enlarge the area within the white square.

A number of keys are also used by the program. B returns to the base
Mandelbrot. I allows the position and size of the displayed area to be input
from the keyboard. M allows values to be input to determine melting, as
described by Steve Wright in Fractal Report, Volume 1 Number 2. S saves the
current screen. U returns to the previous plot (or the last plot stored if
the plot buffer is full), and X exits the program after confirmation.

The keys 0-9, +, and - allow the colours to be selected from a range of 20
colour sets. Pressing + results in the keys 0-9 selecting colour sets 10-19,
while pressing - results in them selecting colour sets 0-9. Once the
appropriate colour set has been selected, clicking Menu will redraw the
screen using the new colours.

Screens are saved in a squashed format using the ScreenSquasher module
(!MandlPlot.Squash). They are saved under the filename MPicN, where N starts
at 1 and increments with each save operation. The files are saved in
<Plot$Dir>, which unless defined elsewhere is set to !MandlPlot.Pics. The
screens can be reloaded using the *PicLoad command in the ScreenSquasher
module, or by double-clicking on the files from the Desktop.
