Can we have RPN back?

[Jake Schwartz]

Quote:I also cannot find a reference to RPL in the HP-28 and HP-48 series manuals, only RPN.

In case this hadn't yet been mentioned, the August, 1987 issue of the Hewlett-Packard Journal (dedicated primarily to the 18C/28C) has an article by Charlie Patton, titled "Symbolic Computation for Handheld Calculators" starting on page 21, where he states: "The ultimate result is a combination of features from both Lisp and Forth that we call the ROM-based procedural language, or RPL." He uses "RPL" throughout the remainder of the article. And Bill Wickes and Charlie Patton refer to it as RPL in their June, 1991 HP Journal article "The HP48SX Scientific Expandable Calculator: Innovation and Evolution". Also, I recall Bill Wickes' HP28C presentation at the PPC Washington DC chapter meeting on February 5th, 1987 where he introduced the term RPL, calling it "Reverse Polish Lisp". (I lugged my 20 pounds of primitive video gear a hundred miles south from New Jersey to the University of Maryland to videotape that one.....it was definitely worth it)
