Dear Jim, thanks a lot for providing very interesting information about the early stages of GRASS! I am one of the new GRASS developers and enjoy discovering gems in earlier versions of GRASS that got lost at some stage. With regard to the combine program of Van Warren, I think that most of its functionality is now covered by r.mapcalc which is by now one of the most important GRASS modules because of its versatility. Moreover, those features that were ** NOT YET AVAILABLE ** in combine are now available in r.mapcalc. The one single exception I could find is the group operator which should be easy to (re-)implement.
A large proportion of the code of the first few GRASS versions is a kind of quality assurance. It is amazing that code written 20 or more years ago is still able to address the problems of tomorrow, giving GRASS an advantage over other, younger GIS software packages.
