RPLは、ヒューレット・パッカード社(HP社)が開発した小型電卓のオペレーティングシステム (OS) の一部であり、アプリケーションプログラミング言語である(初期開発者によるとReverse Polish Lispに由来する[2][3][4][5][6][7]。一方、HP社のマーケティングは1987年の短い期間の間、RPLから逆にROM-based Procedural Languageという意味をこじつけで作り出そうとした[1][7][8])。

"Several existing operating systems and languages were considered, but none could meet all of the design objectives. A new system was therefore developed, which merges the threaded interpretation of Forth with the functional approach of Lisp. The resulting operating system, known unofficially as RPL (for Reverse-Polish Lisp), made its first public appearance in June of 1986 in the HP-18C Business Consultant calculator."

In the early days of RPL development, we got tired of calling the unnamed system "the new system", and one of the development team came up with "RPL", both as a play on "RPN" which has been the loved/hated hallmark of HP calcs forever, and as an accurate indication of the derivation of the language from Forth and Lisp.
RPL was never particularly intended to be a public term; at the time of the HP Journal article (August 1987) on the HP 28C there was an attempt to create a less whimsical name--hence "ROM-based procedural language," which preserved the initials but had a more dignified sound. The development team never calls it anything but (the initials) RPL. You can choose either of the two full-word versions that you prefer. Or how about "Rich People's Language?"

For a time HP explained the letters RPL as an acronym for "ROM-based Procedural Language"."

By combing elements of RPN, Lisp and Forth, HP came up with a language called RPL (or ROM-based Procedural Language).”
