INTRODUCTION: Fractals Plus is a program designed to produce images of two types of fractals; the Mandelbrot set and all the Julia sets. It has been carefully crafted to do this as fast as possible and in a user friendly manner. Help on how to use the program is available online by pressing the [F1] key. This document contains notes on running the program, and a troubleshooting section. 2. INSTALLING THE PROGRAM: Fractals Plus requires no "installation" procedure as such. It can even be run from the distribution disk! If you wish to run it from your hard disk then you should follow the steps below. 1. Make a new directory for the program by typing the following instruction at your DOS prompt. md \fractals 2. Change to the new directory by typing. cd \fractals 3. Copy all the files from the floppy disk (assumed to be in drive A, if it is not then substitute the appropriate letter in the command). copy a:*.* 4. The program is now installed, easy wasn't it! 3. RUNNING THE PROGRAM: To run the program the current directory *must* be the directory in which the Fractals Plus program is installed. The program can then be started by typing the command: fractals The program should load and show the introduction screen. Press any key to clear this screen and proceed to the main program. 4. SYSTEM REQUIREMENTS: Fractals Plus requires the following setup: þ 8088 or better processor þ 475 kB of available memory (more to load files) þ A VGA, MCGA or better graphics card. It must be capable of displaying the 320x200 mode with 256 colours þ DOS v3.00 or later Optional extras are: þ An 80386sx or better processor for 32-bit mode þ A mouse for mouse operation 5. POSSIBLE PROBLEMS: Whilst loading Fractals Plus may display an error message. The error message will be of the form: "Fractals Plus v2.10 - abnormal exit due to: ???" The possible error messages are listed in this section. "Insufficient available memory" This will occur on loading, or on attempting to load or save a file. It indicates that there is not enough memory for Fractals Plus to run in. Fractals Plus requires at least 475kB of available memory to run, and 500kB if you want to load or save files. Free up some memory by unloading TSRs etc and try running Fractals Plus again. "Can't load palette - required file MBROT.MPL" "Can't load icons - required file ICONS.ICC" "Can't load graphics - required file LOGO200S.GRA" One of these messages will occur on startup if Fractals Plus cannot find a file it requires. The usual problem is that they are not situated in the current directory. You should change to the directory Fractals Plus is stored in, using the "cd" command, before running Fractals Plus. You could also have removed them by mistake, in which case you should reinstall Fractals Plus (see section 2). "Can't find current directory - error code: xxx" This indicates that your DOS version is not compatible with Fractals Plus. If you are using the correct version of DOS then there is some other problem and you should contact the authors. Other problems are usually due to a missing file MAIN.MBT. This contains the image that is loaded on startup. If it is not found in the current directory then Fractals Plus will start up with a blank screen. Do not save an image with this name as you will overwrite the correct startup image. When zooming in the zoom box may appear to the right of the cross-hair mouse cursor. This is due to a problem with Microsoft mouse drivers earlier than version 8.20. You will either have to allow for this (particularly when trying to get Julia sets), unload your mouse driver before running Fractals, or upgrade your mouse driver. 6.
