Just a small example:

Code:
menu status {
  $iif($gison(#TestGroup),Turn group off) :.disable #TestGroup
  $iif(!$gison(#TestGroup),Turn group on) :.enable #TestGroup

  $iif($gison(#TestGroup),$style(1) TEST,$style(2) TEST)
  .Yep - the group is on://echo 4 -a *tada* ^^
} 


alias gison { if ($group($1) == on) { return $true } | return $false }
