My Balfour & Marwick mentions it in passing and declares that they won't talk about it. > While some of the DIPSO instances the E didn't follow immediately (there was a parenthesis or repeat counter), for some it did, and still gfortran complained. In a further twist Ian Howarth saw more errors than I with the compiler he used, possibly the same number at Tim saw. There was a bug fixed in gfortran last year relating to this (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41154), but it seems not to have been included in the version I'd been running as it still complained about a valid "1PE15.3". To add to the confusion there are parallel series of versions, e.g. Version 4.5.0 was released before 4.4.4 which in turn appeared before 4.3.5. Which version are you using Tim? Version 4.3.2 doesn't complain with the old dipso.f unlike 4.5.0. > I'm using GNU Fortran (GCC) 4.6.0 20100703 (experimental) Copyright (C) 2010 Free Software Foundation, Inc. > With other fish to fry at the time I stashed my changes and reverted gfortran so I could complete a make world, then forgot about it. No problem. I learned something that I probably didn't really need to learn :-) -- Tim Jenness Joint Astronomy Centre
