Words from neighbour ones

Words from neighbour ones 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.

Task

Use the dictionary   unixdict.txt
Let's take the words from next characters:
1 <= n < (dictionary lenght) - 9
char1 = 1st character of nth word.
char2 = 2st character of (n+1)th word.
char3 = 3st character of (n+2)th word.
...
char9 = 9st character of (n+8)th word.
newword = char1+char2+char3...+char9
If newword in dictionary then show on this page.
lenght of newword = 9

Ring

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

see "working..." + nl

ln = len(wordList) for n = ln to 1 step -1

   if len(wordList[n]) < 9
      del(wordList,n)
   ok

next

see "New words are:" + nl

for n = 1 to len(wordList)-9

   c1 = substr(wordList[n],1,1)
   c2 = substr(wordList[n+1],2,1)
   c3 = substr(wordList[n+2],3,1)
   c4 = substr(wordList[n+3],4,1)
   c5 = substr(wordList[n+4],5,1)
   c6 = substr(wordList[n+5],6,1)
   c7 = substr(wordList[n+6],7,1)
   c8 = substr(wordList[n+7],8,1)
   c9 = substr(wordList[n+8],9,1)
   str = c1 + c2 + c3 + c4 + c5 + c6 + c7 + c8 + c9 
   ind = find(wordList,str)
   if ind > 0
      add(nextwords,wordList[ind])
   ok

next

nextwords = sort(nextwords) for n = len(nextwords) to 2 step -1

   if nextwords[n] = nextwords[n-1]
      del(nextwords,n)
   ok

next

for n = 1 to len(nextwords)

   see "" + n + ". " + nextwords[n] + nl

next

see "done..." + nl </lang> Output:
