In Kernighan and Pike's book `The Unix Operating System', they develop a
sophisticated calculator program called 'hoc4'. The back of the book has a full
source code listing. I suspect many people have typed this code in by hand, so
it may be available near you. If you can't find it locally, one of my colleagues
here at Melbourne has typed it in, *and* fixed a few bugs in he code (sloppy
mixing of pointer types, &c.), so i could post it if you like.
