Hi, consider this fairly minimal code example: <hansl> open denmark loop i = $tmax..$tmax + 9     catch value = LRM[i]     eval $error     # This line necessary to provoke the problem! endloop </hansl> What I'm getting on gretl 2022c is that in the first loop iteration it works as expected, namely that catch isn't necessary (since LRM[$tmax] gives the last available obs) and the error value is zero.  Directly afterwards for i==$tmax+1 gretl says "index value 56 out of bounds". This is correct, but that's exactly what 'catch' should, well, catch. Notice that when the $error value isn't accessed, then gretl does _not_ complain! But that's not all - what follows is a more complex example without a direct $error access, where the simple loop construct works, but an equivalent while-loop does not work: <hansl> open denmark loop i = $tmax..$tmax + 9     catch value = LRM[i]    # works endloop print "got here?" index = $tmax loop while index < $tmax + 10     catch value = LRM[index]  # fails     index++ endloop </hansl> Could this have to do with the recent "more-compilation" internal gretl business, or did that not make it into gretl 2022c? thanks sven
