Line 1: ~~{{stub\|language}}~~ {{language\|RPL \|exec=interpreted Line 13 ⟶ 11: }} '''RPL''' (an acronym for '''Reverse Polish Lisp''') is the onboard calculator language for the HP-28, [[wp:HP 48 series\|HP 48]] ~~line~~and HP-49/50 lines of graphing calculators. It is a stack language (not a [[Lisp]]-like language, as its name implies), tightly integrated with the ~~HP 48~~calculator system, with many instructions similar to Forth. It can natively handle unsigned integers (named ''binary integers''), floating-point numbers (named ''real numbers''), complex numbers, vectors and matrices (named ''arrays''), lists, character strings, and algebraic expressions. The HP-49/50 models can also handle long integers (up to 500 digits) and benefit from several dedicated built-in functions to work with, including testing and generation of prime numbers. There are actually two languages with the name RPL: '''User RPL''' and '''System RPL'''. System RPL is used in implementing the ~~HP 48~~ operating system, and User RPL is the language users use to write programs on the calculator. System RPL is highly hardware-dependent, whilst User RPL is upwardly compatible. The language [[RPL/2]] is a recreation of this language for POSIX machines.
