As it seems you'd like to learn RPL, you should definitely read Bill Wickes's book "HP-48 Insights Part I (48G/GX Edition)", which is available as part of the MoHPC Document Set, available here. An incredible value that includes hundreds of manuals, books, brochures, HP publications, etc., the small price also helps to pay for this great website.

I strongly second Bob's recommendations, the Wickes book and of course the Museum USB stick.

Also in reference to the above discussions, this bit of code

Code:


 → a «
  »

is referred to in the HP manuals as a "local variable structure". The description of -> (the right arrow character) in the AUR is worth reading as well.
