This is a very good explanation of RPN, and it,s associate languange Forth. For years I worked with the HP 11C in RPN and still have two HP11C calculators which I use on a daily basis, as well as doing a lot of programming in Forth. This article brings back the good old times.

The Forth language is reviewed and explained very well and many links to Forth interests are listed.

Thanks Willi

Hi all

I guess not only new engineering graduates but also some SDR users are
curious what is behind the acronym RPN. Wikipedia explains it and gives
examples at:

http://en.wikipedia.org/wiki/Rpn

RPN was already used on HP´s desktop calculators in the sixties of the past
century.

Two very nice posts Bob.

Glad to see the responses to my mention of RPN. New engineering graduates
I
have mentored on recent jobs had never heard the term.  I don't consider
mentioning my still functional (no battery required) Post and K&E bamboo
sticks
to them.
