I tried to reply here but the silly editor seems to think I imbedded code in the reply and rejected it. See the sextant topic for more.

Gotit about telephone books. Me, I go with "cookbook reductions".

Now that you mention it, I recall at least one other RPN calculator line but, for the life of me, can't think of the name. Even the Wikipedia article on RPN is silent about this. Odd...

Tell me about "Telephone Book Arithmetic" - that's one I haven't heard. Nothing wrong with the 11C - BTW, isn't that one of the RPN calculators that HP put out? I use a TI 2000 (not quite a computer and more than a calculator) running StarPilot, which I like a lot. I used to work with a Celesticomp until I found out about an interesting flaw in the programming.
