[ns] passing parameters to tcl script

[pedro chaparro]

hi every one, i have a question about how to check the number of parameters
i pass to the tcl script, i'm using

if {  $argc != 3}
{
puts "Missing parameters  "
exit 1
}

but it does not work

i got this error

pepe at calvin:/home/pdro7/Desktop/ns-allinone-2.34/ns-2.34# *./ns
foreman1.tcl 4444 3333 2222 *
wrong # args: no script following "  $argc != 3" argument
    while executing
"if {  $argc != 3}"
    (file "foreman1.tcl" line 7)



thanks in advance
