    IDirectMusicLoader8*      m_pLoader;
    IDirectMusicPerformance8* m_pPerformance;

public:
    CMusicScript(IDirectMusicPerformance8* pPerformance, 
                  IDirectMusicLoader8* pLoader,
                  IDirectMusicScript8* pScript);
    virtual ~CMusicScript();

    inline  IDirectMusicScript8* GetScript() { return m_pScript; }
    HRESULT CallRoutine(TCHAR* strRoutine);
    HRESULT SetVariableNumber(TCHAR* strVariable, LONG lValue);
    HRESULT GetVariableNumber(TCHAR* strVariable, LONG* plValue);
    HRESULT SetVariableObject(TCHAR* strVariable, IUnknown *punkValue);
    HRESULT GetVariableObject(TCHAR* strVariable, REFIID riid, 
        LPVOID FAR *ppv);
};
