[ns] trace file

[Abbas Makki <abbas.makki@kcl.ac.uk>]

hi all

In trace file for example the command

$ns at $fo "$now $bw"

would write repetitive values. Good for X-graph.

I would like to cut these repetitive values to save space and also to export to 
spreadsheet. How may I do this ?

I played with synchronised times like

set count [expr $now + $step]

I ended up with the same problem, only a delay factor results. That is instead 
of starting at zero time it starts at step time.

Appreciate all suggestions.
