What comes next?

[Thomas Klemm]

I wondered why I used this in my T program but now NXT also works with a single element list:

Code:

\<< DUP LST OVER
  WHILE DUP SIZE 1 >
  REPEAT \GDLIST DUP LST ROT + SWAP
  END DROP
\>>

Also the usage is similar to my initial program since the last + command was removed.
If the prediction of what comes next matches, add it to the list.
Otherwise DROP it and add the proper one.
