Explanation: Easy to understand or not?? uhhm lets see. The first routine save in the memory, don't mater where :), any thing that is in the display. After that you can what you want with the display. When you want display what you have saved call zapi83 with the 13->X routine and the saved data will be displayed. understand? Now the two following routines. Some times you use routines in the zapi83 that need storage in the Y if you want display or not display the result of the routine (for example the Rectangle filled). This things are storage in the graph buffer. Use 14->X if you want clear the graph buffer or use 15->X if you want display the graph buffer. You understand better that routines if you work with them.
