This is the code I used for my HP-48 instead of \<< NDUPN DROP \>>:

Code:

\<<
  "" SWAP
  WHILE DUP 0 >
  REPEAT
    ROT ROT OVER +
    ROT 1 -
  END
  ROT DROP2
\>>

Wasn't particulary proud but handles both 0 and negative values correctly. Whatever that is.

Not sure about that. It has indeed to do with what we pass to DOLIST. But then just returning nothing instead of an empty list is a surprize to me as well.
