I now have the user's guide but (blush) can't find the SWAP command. I'm so dumb. There's nothing in the index pages, not even for ROLL. Can anybody tell me where to find the SWAP command so I can swap numbers on the stack?

Press the right-cursor (not right-shift) button to perform the swap function (unless you're doing something where it would make sense for it to move the cursor to the right, of course) There is a ROLL function on the 48Gii (press TOOL, STACK, NXT), but it behaves differently from the ROLL function on RPN calculators. Since the stack is not limited, you must tell it how many levels you wish to roll. Also, ROLL actually does a roll-up. Use ROLLD to roll-down. Pressing DEPTH ROLLD will perform the closest thing to the RPN roll-down function.
edit - I should have stated that I am far from an expert in the operation of RPL machines, and that others would probably provide more, better and/or corrected information.

There is another caveat with the swap button (right arrow)...you can't use it if there is a command line present...you must hit enter first to put whatever is in the command line into level 1 of the stack. In that regard it's not quite as efficient as an RPN machine. |
