Forums mIRC Help how do i create a channel part message

alias part { 
;; Has the user specified a channel? If no, use the current one
  var %chan = $iif($1 ischan,$1,$chan)
;; default message
  var %msg = cheerio folks

;; Do we have a user-defined message? If so, use that instead of the default
  if (($1 ischan) && $2) { %msg = $2- }
  if ($1 && $1 !ischan) { %msg = $1- }

;; do the part
  !part %chan %msg
