Per the additional information you supplied via pm, this should work as you want it.
Code:
alias f4 {
  var %msg = $$?="Enter message for Ops only to see here"
  .notice $($+(@,$chan),2) %msg
}
alias f5 {
  var %msg = $$?="Enter message for Ops only to see here"
  .notice $($+(@+,$chan),2) %msg
}

This is untested, as I don't have an account on the network you specified in pm.
