This may be of interest for folks thinking about purchasing a NEC/4 license 
for use with 4Nec2.  The one-time license fee is now $300 though Lawrence 
Livermore National Labs.  This is a lot less than it was a few years ago.

The CD-ROM came with updates including versions 4.1 and 4.2  It also came 
with a whopping 213 page user manual!  However, it seems that 4Nec2 defaults 
to the NEC4D1200.EXE engine when selecting NEC/4 in the menu.  That engine 
is not fully "operational compatible" with 4Nec2.  For one thing the DOS 
window doesn't close automatically after the model run time is complete.

By trial and error, I "fixed" the problems by using the NEC/4.2 control 
console .exe.  So, file NEC42W32CL.exe was re-named to NEC4D1200.exe in the 
EXE sub-directory since 4Nec2 defaults only to the NEC4D1200 file name when 
selecting the NEC/4 engine in the menu.  Hopefully, Arie will incorporate 
more pull-down engine options in the future.

NEC/4 is now working just like NEC/2 in 4Nec2 software, only with better 
accuracy for some ground-related applications.
