Hi friends,
I have written the below code which is compiled with codevisionAVR:
Code: 
typedef struct {
    unsigned char QAddrHi;
	unsigned char QAddrLo;
	unsigned char QcountHi;
	unsigned char QcountLo;
	unsigned char RByteCount;
	unsigned int RNum;
	unsigned char RData[NumDefault];
} IOData;
IOData.QAddressHi=*data;

data is the name of an array and it's type is unsigned char;
but this error appears:illegal symbol.
 

What about that:

Code: 
typedef struct {
    unsigned char QAddrHi;
	unsigned char QAddrLo;
	unsigned char QcountHi;
	unsigned char QcountLo;
	unsigned char RByteCount;
	unsigned int RNum;
	unsigned char RData[NumDefault];
} IOData;
IOData MyData;

int main() {
   MyData.QAddressHi = *data;
}

EDIT: Of course it does not work, because QAddressHi does not exists in your structure.
