Victor,
     thanks for that example.  I'm looking to see how to adapt to to
the code we've already built; since that was modeled after the
examples too hopefully it won't be too difficult.

     Of course all of this is just highlighting how rusty I am at 'C'
and nets and bolts programming these days.
