Re: [Gretl-users] error when using the summary command (core dumped)

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: <hansl> open prod.txt string D = readfile("pnames.txt") string line loop i=1..$nvars-1 -q getline(D, line) setinfo $i --description="@line" endloop labels </hansl> Note that here we're using "$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): <hansl> loop i=1..$nvars-1 -q getline(D, line) list Li = i setinfo Li --description="@line" endloop </hansl> Allin Cottrell
