/*说明**************************************************************************
曲谱存贮格式 unsigned char code MusicName{音高，音长，音高，音长...., 0,0}; 末尾:0,0 表示结束(Important)

音高由三位数字组成：
个位是表示 1~7 这七个音符
十位是表示音符所在的音区:1-低音，2-中音，3-高音;
百位表示这个音符是否要升半音: 0-不升，1-升半音。

音长最多由三位数字组成：
个位表示音符的时值，其对应关系是：
|数值(n):  |0 |1 |2 |3 | 4 | 5 | 6
|几分音符: |1 |2 |4 |8 |16 |32 |64 音符=2^n
十位表示音符的演奏效果(0-2):  0-普通，1-连音，2-顿音
百位是符点位: 0-无符点，1-有符点

调用演奏子程序的格式
Play(乐曲名,调号,升降八度,演奏速度);
|乐曲名          : 要播放的乐曲指针,结尾以(0,0)结束;
|调号(0-11)    : 是指乐曲升多少个半音演奏;
|升降八度(1-3)    : 1:降八度, 2:不升不降, 3:升八度;
|演奏速度(1-12000): 值越大速度越快;
