C#

Hi,
I have one C# code as below:

internal int Calc(double bbMacd, double avg, double upperBand, double lowerBand, double smallTrigLine, double largeTrigLine, double smallTrigLineAvg, double largeTrigLineAvg, int keltnerDir, double keltnerTop, double keltnerMid, double keltnerBot, double supVal, double resVal, out bool LMacdOK, out bool SMacdOK)
		{
			bool item;
			bool flag;
			bool flag1;
			bool flag2;
			bool flag3;

Some calculation here

bool& lMacdOK=LMacdOK;
			if (flag4 || flag5)
			{
				flag2 = true;
			}
			else
			{
				flag2 = flag7;
			}
			*(lMacdOK) = flag2;
			bool& sMacdOK=SMacdOK;
			if (flag4 || flag5)
			{
				flag3 = true;
			}
			else
			{
				flag3 = flag6;
			}
			*(sMacdOK) = flag3;
			return 1;
		}
	}
}

After compile get below errors:
Identifier expected Error CS1001. I got this error for below two lines:
bool& lMacdOK=LMacdOK;
bool& sMacdOK=SMacdOK;

How to solve this?
Regards,
