In sec. 4.5.8 at the top of page 50, it reads: "cp case.in0 case.in0_grr and change indxc to 50"
It is not clear from this sentence whether the change has to be made in case.in0 or case.in0_grr (in the latter, it turns out, as the alternative leads to an immediate crash, for luck). A more precise sentence would be: "cp case.in0 case.in0_grr and change indxc in case.in0_grr to 50" Otherwise, a nice new version, this 10.1 -- installs fine, runs fine. Stefaan
