So it looks like the below

on *:TEXT:!remword*:#: {
  if ($2 !isalpha) { notice $nick Words on the list only contains letters. | halt }
  var %d = $read(hangman.txt, w, $$2)
  if (( %d == $null )) { notice $nick That word is not in the list | halt }
  write -ds $+ $$2 hangman.txt $$2
  msg # The word $$2 has been removed.
}
