RE: hp 28s - creating nested lists
For those who don't know how the original NDUPN code looks like, this is the code of the HP28S (the HP28C source code, not byte code is equal):
3ACB5 76C20  ::
3ACBA A4020    DUP
3ACBF 71E60    #0=
3ACC4 F5CD3    case
3ACCE A4020    DUP
3ACD3 F7F60    #1-
3ACD8 A4020    DUP
3ACDD 71E60    #0=
3ACE2 F5CD3    case
3ACE7 60120    DROP
3ACEC 9A170    ZERO
3ACF1 8C850    DO
3ACF6 48120    OVER
3ACFB 5E020    SWAP
3AD00 50850    LOOP
3AD05 09F20  ;

A special feature is the valid 0 argument for N.
