[Gretl-users] Delete bundle elements within a loop

Hi all, I trying to delete bundle elements using a loop. However, this seems to be forbidden at the moment. Or do I something wrong here? I am using latest git on Ubuntu 19.10. <hansl>     bundle b = defbundle("A", 1, "C", 3)     strings S = defarray("A", "B", "C")     loop i=1..nelem(S) -q         string key_name = S[i]         if inbundle(b, key_name)             delete b["@key_name"]         endif     endloop     delete b["A"]    # works </hansl> Thanks, Artur
