    I got the solution.. 

    initialise the variable outside the function as functionname.variable=value;

     

     

    CompareClassicCAT.rowNo = 1; //static variable
    CompareClassicCAT.colNo1= 2; //static variable
    CompareClassicCAT.colNo2= 3; //static variable


    function CompareClassicCAT(img1,img2)
    {

    var fileName,rowNo,colNo1,colNo2, sheetName, content;
    fileName=Project.ConfigPath+"\AutoDataSource\\CATRegressionCompareTestResults.xls";

    sheetName="Test_Result";

    if(Regions.Compare(img1,img2))
    {
    CompareClassicCAT.rowNo++;
    AddDataToExcelFile(fileName, sheetName, CompareClassicCAT.rowNo, CompareClassicCAT.colNo1, img1);
    AddDataToExcelFile(fileName, sheetName, CompareClassicCAT.rowNo, CompareClassicCAT.colNo2, "Identical");
    Log.Message(img1 + " is identical");

    }
    else
    {
    CompareClassicCAT.rowNo++;
    AddDataToExcelFile(fileName, sheetName, CompareClassicCAT.rowNo, CompareClassicCAT.colNo1, img2);
    AddDataToExcelFile(fileName, sheetName, CompareClassicCAT.rowNo, CompareClassicCAT.colNo2, "NOT Identical");
    Log.Message(img1 + " is NOT identical");

    }
    }

declare the variable in global so it won't reset.

    Ok But where to initialise the variable as i need to initilise it inside my function and when I call that function again it is reinitilising.
