When I try to reproduce this problem I get an error because
there is a missing quote to terminate "%g".   If I add the
quote, then it works with no error.  But I had to invent
functions and constants fro ampl Lor_D W and so on.
Can you either provide the full script or reduce the problem
to a stand-alone command?
