Re: [ns] Setting bound variables during simulation

["Benoit Pinguet" <bpinguet@genista.co.jp>]

If I run this script instead of getting :
loss rate set to 0
loss rate set to 0.01
loss rate set to 0.02
.....
loss rate set to 0.25

as an output, I just get
loss rate set to 0
loss rate set to 0
loss rate set to 0
loss rate set to 0
.....

I could not solve this problem.
 If I use 25 different loss modules previously created instead and use the
instructions :

set loss_module($j) [new ErrorModel]
$loss_module($j) unit pkt
$loss_module($j) ranvar [new RandomVariable/Uniform]
$loss_module($j) drop-target [new Agent/Null]
$loss_module($j) set rate_ [expr 0.01*$j]
$ns at [expr $j] "$ns lossmodel $loss_module($j) $n0 $n1"

instead of
$ns at [expr $j] "$loss_module set rate_ [expr 0.01*$j]"

now it works and I get the correct output but I still don't understand why
the previous loop did not work.
Thanks for your help
