Probably I am missing some subtlety of the RPN Roll behaviuor, could you please help me to understand what happens?
Thanks.

The behaviour you should have IMHO is ...

with data entry then with a bunch of roll down
Code:
Key    X  Y  Z  T  L  StackLocked
1      1  ?  ?  ?  ?  ?
ENTER  1  1  ?  ?  ?  yes
2      2  1  ?  ?  ?  yes
ENTER  2  2  1  ?  ?  yes
3      3  2  1  ?  ?  yes
ENTER  3  3  2  1  ?  yes
4      4  3  2  1  ?  yes
RDN    3  2  1  4  ?  no
RDN    2  1  4  3  ?  no
RDN    1  4  3  2  ?  no
RDN    4  3  2  1  ?  no

with data entry mixed with roll down
Code:
Key    X  Y  Z  T  L  StackLocked
1      1  ?  ?  ?  ?  ?
RDN    ?  ?  ?  1  ?  no
RDN    ?  ?  1  ?  ?  no
RDN    ?  1  ?  ?  ?  no
RDN    1  ?  ?  ?  ?  no
2      2  1  ?  ?  ?  no
RDN    1  ?  ?  2  ?  no
RDN    ?  ?  2  1  ?  no
RDN    ?  2  1  ?  ?  no
RDN    2  1  ?  ?  ?  no
3      3  2  1  ?  ?  no
RDN    2  1  ?  3  ?  no
RDN    1  ?  3  2  ?  no
RDN    ?  3  2  1  ?  no
RDN    3  2  1  ?  ?  no
4      4  3  2  1  ?  no
RDN    3  2  1  4  ?  no
RDN    2  1  4  3  ?  no
RDN    1  4  3  2  ?  no
RDN    4  3  2  1  ?  no
