[Gretl-users] passing a series name to a function

Suppose I want a function that may be applied to one series (for example, "income") so that the function produces several output series (for example "trend", "seasonal", etc). The function may be: function decomp(series y, list comp) # some calculus ... series y_trend = ... series y_seasonal= ... list comp=y_trend y_seasonal return list comp end function at present, if you run this type of function on a series, for example: list components=decomp(income) you get a new list "components" with elements "y_trend" and "y_seasonal". The question is: Is there a way to pass the name of the variable to the function, so that the function can generate new series which change the names depending on what series are applied to? For example obtaining names "income_trend" ... when applied to "income" and names "consume_trend"... when applied to consume. -- Ignacio Diaz-Emparanza DEPARTAMENTO DE ECONOMÍA APLICADA III (ECONOMETRÍA Y ESTADÍSTICA) UPV/EHU Avda.
