RE: [ns] beginner question (help!)

Thanks for your help; it does indeed hang after it prints "running nam".  Is
it possible that it's not finding the nam.exe file because I need to set
some environment variable, alter my path, etc? (I'd heard something about a
"HOME" variable at some point?).

Thanks,

Sebastian

Try to use this finish():

proc finish {} {
         global ns nf
         $ns flush-trace
         close $nf
         puts "running nam"
         exec nam out.nam &
         puts "nam finished"
         exit 0
}

Then you'll know whether it hangs in "exec nam ...". If yes,
just delete the "exec nam ..." and run nam manually:)
