yeh, they arent needed i think they got the idea from that listops thing in the help file and just played around with it.

rolz14 , you could use a loop like this

alias cusers {
var %i = 0
while ($nick(#,%i) != $null) {
inc %i
if ($nick(#,%i) == $null) {
msg $chan 10 $+ There is Currently $calc(%i - 1) users on the channel!
}
}
}
