Using Assignment Operator
The main reasons you may want to use assignment are:
 * You need to set the default value for a question that does not accept defaults via equation (such as list radio, where the user interface lets you pick one of the answer options, but does not let you enter an equation).  However, be careful, as LimeSurvey will not be able to validate that your equation generates one of the allowable answers for that question.
 * You need to forcibly change the response to a previous question based upon a later response
 * etc...
