Harini, The expression actor simply evaluates the expression, and places the result on the output port. So, if you have two ports (a1, a2) and the incoming value to a1 is 3 and incoming value of a2 is 5, then the expression 'a1' will output 3 on the output port, and the expression 'a1 + a2' will output 8 on the output port. See the attached figure for an illustration. Maybe I'm missing the point of your question?
