Allin (and friends), Another question I see is not well resolved, IMHO, is when you want to prepare a package function that produces a list of series. In this case, the dialog box of the f. package that appears to the user has a field entitled: "Assign return value(optional): Selection or new variable... " and a box field to select an already defined list or to define a new name. (See for example the function package Brown in the server). Recently I saw (newbie) users very confused about this field. As this field was optional they only selected the other params, cliked on accept and got nothing. I had to tell them to put a new name into that field for the package to work (and then I modified the function so that now at least the output is displayed in a text window). I think it could be solved if the function programmer could put a default value for the (new) defined list. -- Ignacio Diaz-Emparanza DEPARTAMENTO DE ECONOMÍA APLICADA III (ECONOMETRÍA Y ESTADÍSTICA) UPV/EHU Avda.
