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 (programming language)|Forth]] and [[Lisp (programming language)|Lisp]].<br />RPL was never particularly intended to be a public term; at the time of the [[HP Journal]] article (August 1987) on the [[HP-28 series|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?"
