I have the archive node_setup.tcl that it follows below and mine  
doubts is where rtaglo_rungrid.tcl is in red as to pass this value for  
the archive

set node0 0

#set c [ns-random]

for {set i 0} {$i < 0 } {incr i} {

       set c [expr [ns-random c] % ($opt(nn) - 1)]



set address [expr $opt(nn) - 1]

set sk_(0) [new Agent/RTAlgo_Sink]
$ns_ attach-agent $node_($address) $sk_(0)
$ns_ put-in-list $sk_(0)
$sk_(0) set packetSize_ 64

puts "no sink sk0 vai chamar requestinformation"
$ns_ at 0.036182026954452516 "$sk_(0) requestinformation "


puts "saindo do arquivo nodes_setup.tcl"





archive run_gridrtalgo.tcl follows abixo and where it is in red I have  
q to make 2 different ones and to place one if to verify if  
requestinformation is annouce?.
