3:38 a.m.
When I run the standard script for estimating the Klein model (klein.inp from the Practice
file... submenu) I get a popup window saying
'I' shadows a function with the same name
But I is a variable and not a function. So I don't see what the problem is.
And gretl turns into waiting mode (revolving indicator in the klein output window).
I have to close the popup window before Gretl continues.
I find this very annoying. In my opinion it would better and more user friendly if either
-- the popup window would not have to be closed before getting on with it
-- this warning message appeared in the output of the script that is being run (e.g. ) at
the top
-- even better would be to not give this message for variables
I prefer the third and second option.

We discussed that point not so long ago on this list. The potential
problem has to do with lags, as in "I(-1)" : such constructions are
hard to distinguish from function calls.

Agreed, the behavior you describe is not nice and it should be
improved.

We discussed that point not so long ago on this list. The potential

In this case actually could sometimes be impossible I guess: Is "I(2)" a
two-by-two identity matrix or the second lead of the series "I"? Who
knows...
Probably one wouldn't choose such a one-letter name 'I' for a built-in
function anymore because of these shadowing issues, but this function is
so widespread it cannot be easily replaced.
However, the error message leaves the user puzzled I guess. First of
all, what is 'I' supposed to refer to? If you don't know the script or
the dataset well it's not clear. Perhaps better to say "The dataset
series 'I' shadows...".
Secondly, what is the consequence? There is no hint as to what is going
to happen or why it matters. So perhaps add a second sentence in the
warning like "Console or script commands might be wrongly interpreted."
Agreed, the behavior you describe is not nice and it should be
improved.
Also agreed.
