Re: [Gretl-users] Use variables as indexes in a script

I need to extract selected data from different vectors and insert them in a variable of the panel. I wrote this simple program, but it does not work: loop i=1995..2005 y = $i-1994 o = 1 loop foreach j 5 6 8 22 23 27 28 29 35 40 42 44 45 56 67 73 74 76 84 85 genr Sd[o:y] = RD$i[$j,1] o++ endloop endloop The problem is that I cannot use the variables y and o I defined like the index variables of the loops (i and j) in the command Sd[o:y] (or Sd[$o:$y]). Is there any way to make the script work?
