see "ABC words are:" + nl

for n = 1 to len(wordList)

   bool1 = substr(wordList[n],"a")
   bool2 = substr(wordList[n],"b")
   bool3 = substr(wordList[n],"c")
   bool4 = bool1 > 0 and bool2 > 0 and bool3 > 0
   bool5 = bool2 > bool1 and bool3 > bool2
   if bool4 = 1 and bool5 = 1
      num = num + 1
      see "" + num + ". " + wordList[n] + nl
