Промених целия код и компилатора включително.Сега работи и на Proteus sim и на реален pic18.Proteus след Reset ми позволява отново да въвеждам символ и диода свети.Това обаче не се случваше с предишния код ,дори и след като бе модифициран!Да не говорим,че в реален pic изобщо диода не светваше.За съжаление функцията Delay10KTCYx(250);не гаси диода.Сега ще се опитвам да го гася чрез Timer0.Това е новият код:
