Please send me the production rules from `position'.

Are you sure?  This is undocumented.  A PLACENAME has to start with an
uppercase letter according to the manual.

What about this:

  box with 0,0 at (0,0)

Implementing a production rule for `with (0,0)' is easy, but `with
0,0' causes a lot of shift/reduce conflicts in GNU pic's grammar
(well, I'm a novice in using yacc, so I don't know yet how to fix such
problems properly).
