Your thoughts were helpful, and I also hope that an experienced person with the -mim- command might offer some insight.

AFAIK, P. Royston, its author, does not post to the list regularly, so he is unlikely to comment, either. But there are probably more experienced listers who can step in... Note that my -mata- code was way too complicated as you have now revealed that you are a beginner. Sorry about that...
