[loulou7593]

j'ai fait donc comme ca

tclcopier

bind pub n .needop needop
proc needop {nick host hand chan arg} {
	global botnick  
	  set Niubot [lindex $arg 0]
	  set pass [lindex $arg 1]
      channel set $chan need-op { putserv "PRIVMSG $Niubot :op $pass" }
	  return 0
}

Mais maintenant j'ai cela comme erreur
[22:47] Tcl error in script for 'need-op':
[22:47] wrong # args: should be "putserv text ?options?"
[22:48] Tcl error in script for 'need-op':
[22:48] can't read "Niubot": no such variable
