Calling to super fails

Hi,
I have a class called SubSystem that implements a method void description(). In my subclass I then try to call super's implementation, but I get the following

error: 'super' was not declared in this scope.

Here is the code:

class MachineGun : public AirplaneSubSystem
{
    public:
        MachineGun(char *name, int led);
        ~MachineGun();
        void run();
        void setOn(boolean flag);
        boolean isOn();
        void description();

    private:
        int myLed;
        boolean myIsOn;
        int myState;
        unsigned long myThreshold;
        unsigned long myTimestamp;
};

void MachineGun::description()
{
    super.description();
    Serial.print(" isOn = ");
    Serial.print(myIsOn);
    Serial.print(" state = ");
    Serial.print(myState);
}

Any help is greatly appreciated.

Hi Greg--

"super" is a java keyword. Assuming you mean to call the base class implementation of "description", use this C++ syntax instead:

void MachineGun::description()
{
    AirplaneSubSystem::description();
    Serial.print(" isOn = ");
    Serial.print(myIsOn);
    Serial.print(" state = ");
    Serial.print(myState);
}

Thanks Mikal, the links I browsed on google was saying to use super.method(); They're off my christmas card list now!
