yes it's possible with tcl
argv is a list wich reprepresent the arguments, (you should use lindex )

and argc the number of arguments
for example
ns ___.tcl 1000 FQ
and code contains something like
if { $argc != 2} {
    puts stderr {usage: ns ___.tcl pktsize queue}
    exit 1
}
Agent/TCP set packetSize_ [lindex $argv 0]
$ns duplex-link $node3 $node4 1.5Mb 10ms [lindex $argv 1]

Good luck
