Furthermore, also about the LIST in function packages, if I
generated
r_1=r(-1), r_2=r(-2), ... (via GUI), these (lagged) variables can be
selected in which the input parameter are declared as a "series." But
I have a LIST input parameter in the function package and press "more"
button to additionally define a new named list, these lagged variables
(i.e., r_1, r_2, ...) do not appear in the available selection list.
I've now added a check box in such list-creation dialog boxes,
marked "Show lagged variables". If you check this box then any
lagged variables that have been added to the dataset will become
visible and can be added to the new list.
I've also fixed something that Sven Schreiber mentioned recently.
Suppose a function package has more than one list argument, but at
least one of those arguments is optional. At first an optional
list argument would appear as "null" in the GUI. But then if you
created a named list, this new list would appear in _all_ of the
argument slots where a list is expected, and the "null" value
would no longer appear to be available for any argument.
Now "null" should remain a visible choice where a list argument is
optional.
