RPL (programming language) The RPL programming language (RPL meaning ROM-based procedural language following Hewlett-Packard or, alternatively, Reverse Polish LISP) is a handheld calculator system and application programming language used on Hewlett-Packard's engineering graphing RPN calculators of the HP-28, HP-48, HP-49 and HP-50 series, but it is also usable on non-RPN calculators, such as the HP-39 series. RPL originated from HP's Corvallis, Oregon development facility in 1984 as a replacement for the previous practice of implementing the operating systems of calculators in assembly language.[2] According to a quote by Dr. William Wickes, one of the original RPL developers, "the development team never calls it anything but (the initials) RPL. "[3] The internal low- to medium-level variant of RPL, called System RPL (or SysRPL) is used on some earlier HP calculators as well as the aforementioned ones, as part of their operating system implementation language.
RPL control blocks are not strictly postfix. PostScript. PostScript (PS) is a computer language for creating vector graphics. It is a dynamically typed, concatenative programming language and was created by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton[1] in 1982. It is best known for its use as a page description language in the electronic and desktop publishing areas. History[edit] The concepts of the PostScript language were seeded in 1976 when John Warnock was working at Evans & Sutherland, a computer graphics company. Concurrently, researchers at Xerox PARC had developed the first laser printer and had recognized the need for a standard means of defining page images. Warnock left with Chuck Geschke and founded Adobe Systems in December 1982. However, the cost of implementation was high; computers output raw PS code that would be interpreted by the printer into a raster image at the printer's natural resolution.
PostScript Level 1[edit] The first version of the PostScript language was released to the market in 1984. Onyx (programming language) Factor (programming language) Factor is a stack-oriented programming language created by Slava Pestov. Factor is dynamically typed and has automatic memory management, as well as powerful metaprogramming features. The language has a single implementation featuring a self-hosted optimizing compiler and an interactive development environment. The Factor distribution includes a large standard library. Factor is a dynamically typed, functional and object-oriented programming language.
"hello world" print print is a word in the io vocabulary that takes a string from the stack and returns nothing. Not all data has to be passed around only with the stack. . : make-html ( string -- xml ) dup <XML <html><head><title><-></title></head><body><h1><-></h1></body></html> XML> ; The word dup duplicates the top item on the stack. Factor includes a large standard library, written entirely in the language. Factor is implemented in Factor and C++. Official websiteSlava Pestov (October 27, 2008).
