This is described in: Cumming, S.G., and P.J. Burton. 1993. A programmable shell and graphics system for forest stand simulation. Environmental Software 8:219-230. A more advanced version, called zelig++, and some cursory documentation are available by anonymous ftp from grebe.geog.ubc.ca Phil Burton =========================================================================== burton@unixg.ubc.ca Philip J.
