|Output variable(s)||This read-only text box displays the name of the variable through which the output of the new method/function will be passed to the calling method/function. Depending on your choice in the Return output variable(s) through area, this variable either will be used in a return statement or will be declared as the passed by reference parameter of the new method/function.|
