Ah, the example you cite dates from January 2014, and since then we have made substantial changes to the gretl command interpreter. You're right, the particular phrasing of that loop no longer works. Arguably, it was only by a strange hack that it worked in the first place. The argument to "setinfo" should be the name or ID number of a series; at the time of writing that script, the scalar variable named "i" was being read as containing the ID number of a series -- that's what I'm describing as a strange hack (since in general in gretl commands you cannot give the name of a scalar where the name of a series is required). Anyway, here's a version that will work with current gretl: open prod.txt string D = readfile("pnames.txt") string line loop i=1..$nvars-1 -q getline(D, line) setinfo $i --description="@line" endloop labels Note that here we're using "$i" (string substitution) to get the name of the series into the "setinfo" command. Here's another variant of the loop that will work (treating the argument to "setinfo" as a list with a single member): loop i=1..$nvars-1 -q getline(D, line) list Li = i setinfo Li --description="@line" endloop Allin Cottrell _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
