Your script is interpreted.  It is not necessary to figure out the
shadowing and mirroring to write simulation scripts.

and have not been successful in writng your own simulation scripts.  If
my impression is wrong, my apologies, please le me know, and I will

A good place to start figuring out how to setup a simulation is
to look in the examples directory, in tcl/ex.  I'd start with simple.tcl,
and then go on to other examples more suited to your interests.

It is easier to figure out how the shadowing works at this point,
by looking at the documentation, and the sources close theareas of
your interests.  If you like, we can discuss some more at that point,

Thanks,
