User in channel check - mIRC Discussion Forums

How can I set a variable to check that a person, who sends me a message, is currently in any of the channels I am in?

Code:

if ($comchan(nick,0) > 0).....

Yeah, you could use something along the lines of

Code:

 on 1:OPEN:?:*:{
  if ($comchan($nick,0) > 0) { echo -a (Incoming Message) $nick is on a common channel. }
  else { echo -a (Incoming Message) You do not share a common channel with $nick $+ .) }
}

You can edit the message to say whatever you'd like.
