Mandelbrot Generator includes an option to generate a selection of six pictures of the Mandelbrot set. The program takes more than 25 hours to generate all six pictures!
Corrections
Amstrad Action omitted to publish the program to load the six pictures created by Mandelbrot Generator. The listing was published in the September 1987 issue.
Bugs
One of the variables for the first of the six pictures created by Mandelbrot Generator is incorrect, leaving a blank area on the left of the picture.
Mixing Hash and Pound does not adjust HIMEM correctly, which means that the machine code routine will overwrite the first byte of any other data that is already stored just above HIMEM.
