Dear Pankaj,
What the operation the operator "+" you are referring below is doing is a called a "concatenation of strings".
With "Strings" being a "chain of characters".
For example if you write the following simple macro code
        two = 2.0;
        test = "this" + " " + "is" + " " + "a" + " " + "test" + " " + "for" + " " + two;
        print(test);
the result will give you:
        this is a test for 2
Please note that I have defined the variable "two" as a float which is thus automatically transformed into a String (the java operation for doing this would be to use String.valueOf(two)) and tranparently concatened to the rest of the string.
Hoping that my short explanations help you to move further, I wish you a nice day.
My best regards,
Philippe
