[Gretl-users] Bug with string-valued series when storing data

Dear all, I've stumbled about an annoying issue. The following script loads the grunfeld data set which includes the string-valued series "firmname". Restricting the data set to a single firm (Chrysler), re-opening the restricted and stored data set shows that "firmname" still comprises the old meta data as the last print_array() function call shows. Still _all_ firm names are printed, and thus somehow stored on "firmname". I guess the issue has (partly) to do with the (at least for me) special behavior of strvals() which _always_ prints all distinct values of a string-valued series irrespective of the underlying data set is restricted or not. This is with current git under Ubuntu. <hansl> clear set verbose off open grunfeld.gdt -q function void print_array (const strings S) loop foreach i S print "$i" endloop end function printf "\nPrint all distinct string-values of 'firmname'.\n" print_array(strvals(firmname)) smpl firmname == "Chrysler" --restrict store foo.gdt printf "\n\nLoad restricted data set\n" open foo.gdt -q -p printf "\nPrint distinct string-valued firmnames.\n" print_array(strvals(firmname)) # still incl. _all_ firm names </hansl> Artur
