Since you clearly know more about this stuff than me, do you know of the
best freely available software for this which works under Unix? (I use
Sun's Solaris for 99% of the things I do, including sending this
message. I use Solaris on my laptop too, rather than Windows).

Hence I'm almost certainly looking for source code in either C, C++ or
Fortran. Anything that works under Linux would almost certainly be able
to be compiled for Solaris without too much effort.
I found this page:

http://www.si-list.net/swindex.html

which has some source. I downloaded one

Sorry, my knowledge doesn't extend to that of programs suitable for Unix
or Linux. The "Unofficial NEC archives" site is the best I know of for
various compilations. Hopefully some of the other readers can help you out.

My program, EZNEC, has been reported to run under Linux using some
versions of the wine Windows emulator, but not with others. You'll have
a lot more to choose from if you can emulate Windows.
