[ns] GOD in node movement files ?

[Chih-Fan Hsin <chsin@engin.umich.edu>]

Hi,

I use "setdest" to create a node movement file.
I use the node movement file like this.

      set opt(sc)   "./w2-test"
      source $opt(sc)

However, when I run that my tcl file, it says that

      can't read "god_": no such variable

I find "god_" is in the node movement file.
Could anyone give me a hand to solve this  problem?
thanks,
Charles
