Cheiron, this will mainly check for ops:

$nick(#,0,@)

To use a while loop to find all the ops in channel, you can do:

on *:text:$($strip(!findop)):#:findop
alias findop {
  while ($nick(#,$0,@)) tokenize 32 $1- $v1
  $iif($isid,return,.msg #) Opper(s): $2-
}

Syntax: > //echo $findop or > !findop
