No, this is wrong. tbl(1) doesn't show it needs piping to troff, and chem shouldn't show it needs piping to pic. The NAME section is where it starts to go wrong in the version I have here. chem - groff preprocessor for producing chemical structure diagrams I suggest chem - pic preprocessor for chemical-structure diagrams -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
