Note further that the Demo versions of EZNEC operate exactly the same
as the paid versions, except for the number of segments permitted in
the model -- which was not a factor in the model I constructed. I'm
sure that Roy or someone else will correct me if that statement is
provably wrong.

You are correct. The demo is exactly the same as the standard EZNEC
program except for the segment limitation. But I recommend using the
current demo program rather than an older version or revision. Demo
programs can be updated at any time by downloading and installing the
current demo from http://eznec.com/demoinfo.htm. The old program can be
uninstalled first if desired; otherwise the new one will overwrite the
old one. This process won't harm any saved description files.
