Thanks for your input. The pick3 command is nifty, I am not used to use them (because I prefer to put stack objects in variables).


I also added the code in the collection of userRPL code in the hp calc torrent. If you have code to suggest to add (or threads where to look for code), feel free to tell me.

One great resource is One-minute Marvels which has a table of combined stack operations. I agree with David, though, that an exhaustive listing of code fragments is less useful than a good knowledge of RPL commands.

Another idea might be a collection of "rules of thumb". As an example, which I mentioned in another thread, stack operations that take a numeric argument (DUPN, ROLL, PICK, etc.) take about 7 times as long to execute as simple operations (SWAP, DUP, ROT, etc.).
