Re: [ns] beginner question (help!)

[Di-Fa Chang <difac@usc.edu>]

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:)
