Hi Sven,
Thank you for your reply.
What I meant is that, e.g., if I create a list of the code of 50 states
list statelist = AR MA PA ...
I can save this statelist somewhere. Next time I do not need to create this
list again. I just retrieve it from the file. So, when I need to do the data
of the population of the 50 state, I can just create a new list from it by
typing
list statepop = statelist suffix pop
then I can get the state population variable list
ARpop MApop PApop ...
In the reverse case, if I get the list statepop from the variable names in
from the population by state dataset, and I want to get the state code list
from it, I can type
List statelist = statepop strip pop
Then I can get the state code list
AR MA PA ...
Anyway, I can save the lists I created for future manipulation and use,
especially when they are very long lists. Can gretl allow doing that?
Regards
YiMin Chen

Hi,
not sure what you mean: it _is_ possible to save the list members to
separate files and re-open them later on. But I admit that you would
have to write a script for that I guess.
Or do you mean you want to save the definition of a list as a kind of
object in a gretl session file, instead of the values of the series in
the list? I'm not sure if that's implemented.
cheers,
sven
