• Tools$\to$Start Up File: allows the path to ``start-up'' files to be defined. Any procedures contained in these *.lgo format files will then become ``pseudo-primitives'' in the XLogo language. They cannot be edited or changed by the user. You can thus define personalised primitives.

    • Grid: You can choose to draw a grid on the background drawing screen. You can define the width and the height of a square of the grid and the grid color.

    • Border motif: You can choose your own motif for the drawing area's border. (it can be an image or a uniform color).

    • Pen Shape: You can choose the shape of the pen: round or square.
      
    • Drawing Precision: Finally, you can choose the accuracy of the drawing line. In high quality definition, you will especially not have the square effect . Yet do not forget that by increasing the quality you will lose some execution speed.
    • Turtles number: You can choose the maximal number of turtle in mode multiturtle.
      
    • Clear Screen on Editor Leaving: You can choose if you want to clear screen when you leave the editor.
    • Drawing Area's Size: You can choose a personal size for the drawing zone. Otherwise XLogo opens in 1000 on 1000 pixels zone. Be careful, when you increase the size of the image, you might have to increase the memory size of XLogo. An error message will pop up.
    • XLogo's Memory: Consequently, you can also change the corresponding memory space allocated to XLogo. Otherwise it will be a 64 Mo size. You might have to increase it if you want to work on a bigger drawing zone. When you modify this parameter, you must restart XLogo so that the change takes place. Be careful, do not over increase this parameter since it could considerably slow your system down.
