ABC words

ABC words is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

A word is ABC word if "a", "b" and "c" letters appear in alphabetical order.

Ring

<lang ring> cStr = read("unixdict.txt") wordList = str2list(cStr) num = 0

see "ABC words are:" + nl

for n = 1 to len(wordList)

   cnt1 = count(wordList[n],"a")
   cnt2 = count(wordList[n],"b")
   cnt3 = count(wordList[n],"c")
   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
   cnt = (cnt1 = 1) and (cnt2 = 1) and (cnt3 = 1)
   if bool4 = 1 and bool5 = 1 and cnt
      num = num + 1
      see "" + num + ". " + wordList[n] + nl
   ok

next

func count(cString,dString)

    sum = 0
    while substr(cString,dString) > 0
          sum++
          cString = substr(cString,substr(cString,dString)+len(string(sum)))
    end
    return sum
