It's a recent change; see http://lists.wfu.edu/pipermail/gretl-users/2015-January/010568.html The syntax Listname[i] now gives you the series at position i in the list (previously there was no direct way of getting that). To get the series ID number you have to "cast" the list to a matrix: <hansl> open denmark.gdt -q list X = LRM LRY matrix Xm = X loop i=1..2 -q string vname = varname(Xm[i]) print vname endloop </hansl> Allin
