Hi, all,

If I want to run the same simulation for many times, only changing some
parameters, but I want to write data to the same trace file, what should I
do? Is there any such example? 

I tried to use a single $ns for the whole simulation, but I am not sure if
it is possible. Also I am confused about "$ns run". Is there any parameter
for Simulator instproc run? The original code has no parameters defined, but
the NS notes and documents mentioned there are args.

Thanks,
Huiwen
