Little explorations with HP calculators (no Prime)

[pier4r]

While I don't doubt that sysRPL is even more powerful than userRPL, the latter is vast enough for my needs. Also diving too much in the RPL world (and I am already at least down to my knee) is dangerous. Already for all little questions I tend to use the 50g instead of using more sane tools (Hp PPL is already much more sane, even with lists limited to 10k objects, as one could nest them). Again, because the digesting speed of mine is slower than the computing speed of the 50g due to the little time available. And still there is newRPL behind the corner!
