Hello Shafiq
that kind of statetement is usually used to get the value of a class
parameter and not to assigne a value to a variable:
for example ->
proc output_link-statistics { qmon link } {
puts "Link statistics $link :"
puts "Packets:\tparrivals_=[$qmon set parrivals_],\tpdepartures_=[$qmon
set pdepartures_],\tpdrops_=[$qmon set pdrops_]"
puts "Bytes:\t\tbarrivals_=[$qmon set barrivals_],\tbdepartures_=[$qmon
set bdepartures_],\tbdrops_=[$qmon set bdrops_]"
}
in this example the values of the class parameters parrivals_,
pdepartures_, etc of the instance of class qmon (a queue monitor) are read.
Regards,
Gilles
