Print out the propagation delay parameter

[Fusun Inanc <fusun@poptop.ee.psu.edu>]

Hello everyone,

I have a question. I have a simulation which has 10 TCP nodes and every link for 
these nodes have different prop. delay value. 

I want to write those values in a file with other parameters. 

for example:

$ns duplex-link $n(0) $r0 10Mb 10ms DropTail
$ns duplex-link $n(1) $r0 10Mb 20ms DropTail
$ns duplex-link $n(2) $r0 10Mb 50ms DropTail
:
:

puts $average "$i    $avg($i)        delay"

delay is to be the prop. delay parameter... But I don't know how to write it.

Could anyone help me for this? 
Thanks in advance.
