Macro Programming Languages
In computer programming, a macro (short for "macro instruction"; ) is a rule or pattern that specifies how a certain input should be Map (mathematics), mapped to a replacement output. Applying a macro to an input is known as macro expansion. The input and output may be a sequence of lexical tokens or Character (computing), characters, or a abstract syntax tree, syntax tree. Character macros are supported in software applications to make it easy to invoke common Command (computing), command sequences. Token and tree macros are supported in some programming languages to enable code reuse or to extend the language, sometimes for domain-specific languages. Macros are used to make a sequence of computing instructions available to the programmer as a single program statement, making the programming task less tedious and less error-prone. Thus, they are called "macros" because a "big" Block (programming), block of code can be expanded from a "small" sequence of characters. Macros often ...

Operating System
An operating system (OS) is system software that manages computer hardware and software resources, and provides common daemon (computing), services for computer programs. Time-sharing operating systems scheduler (computing), schedule tasks for efficient use of the system and may also include accounting software for cost allocation of Scheduling (computing), processor time, mass storage, peripherals, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computerfrom cellular phones and video game consoles to web servers and supercomputers. , Android (operating system), Android is the most popular operating system with a 46% market share, followed ...

Scripting Language
In computing, a script is a relatively short and simple set of instructions that typically automation, automate an otherwise manual process. The act of writing a script is called scripting. A scripting language or script language is a programming language that is used for scripting. Originally, scripting was limited to automating an operating system shell and languages were relatively simple. Today, scripting is more pervasive and some languages include modern features that allow them to be used for Application software, application development as well as scripting. Overview A scripting language can be a general purpose language or a domain-specific language for a particular environment. When embedded in an application, it may be called an extension language. A scripting language is sometimes referred to as very high-level programming language if it operates at a high level of abstraction, or as a control language, particularly for job control languages on mainframes. The te ...

EULA
An end-user license agreement or EULA () is a legal contract between a software supplier and a customer or end-user. The practice of selling licenses to rather than copies of software predates the recognition of software copyright, which has been recognized since the 1970s in the United States. Initially, EULAs were often printed as shrink wrap contracts, where tearing the shrink wrap indicated acceptance. Software distributed via the internet is more commonly licensed via clickwrap (where the user clicks to agree to the license) or browsewrap (continuing to browse the website indicates agreement). Most companies prefer to sell licenses rather than copies of the software because it enables them to enforce stricter terms on the end user in a number of domains, especially by prohibiting transfer of ownership or use on multiple computers, and by asserting ownership of the copyright of derivative works, such as user-generated content in video games. Enforceability of EULAs has b ...

Massively Multiplayer Online Role-playing Game
A massively multiplayer online role-playing game (MMORPG) is a video game that combines aspects of a role-playing video game and a massively multiplayer online game. As in role-playing games (RPGs), the player assumes the role of a Player character, character (often in a fantasy world or science-fiction world) and takes control over many of that character's actions. MMORPGs are distinguished from Online game, single-player or small Multiplayer online game, multi-player online RPGs by the number of players able to interact together, and by the game's persistent world (usually hosted by the game's video game publisher, publisher), which continues to exist and evolve while the player is offline and away from the game. MMORPGs are played throughout the world. Global revenues for MMORPGs exceeded half a billion dollars in 2005, and the western world's revenues exceeded a billion dollars in 2006. In 2008, the spending on subscription MMORPGs by consumers in North America and Europe gre ...

Spreadsheet
A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. Spreadsheets were developed as computerized analogs of paper accounting worksheets. The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. The term ''spreadsheet'' may also refer to one such electronic document. Spreadsheet users can adjust any stored value and observe the effects on calculated values. This makes the spreadsheet useful for "what-if" analysis since many cases can be rapidly investigated without manual recalculation. Modern spreadsheet software can have multiple interacting sheets and can display data either as text and numerals or in graphical form. Besides performing basic arithmetic and mathematical functions, modern spreadsheets provide built-in functions for common financial ...

Word Processor
A word processor (WP) is a device or computer program that provides for input, editing, formatting, and output of text, often with some additional features. Early word processors were stand-alone devices dedicated to the function, but current word processors are word processor programs running on general purpose computers, including smartphones, tablets, laptops and desktop computers. The functions of a word processor program are typically between those of a simple text editor and a desktop publishing program; Many word processing programs have gained advanced features over time providing similar functionality to desktop publishing programs. Common word processor programs include LibreOffice Writer, Google Docs and Microsoft Word. Background Word processors developed from mechanical machines, later merging with computer technology. The history of word processing is the story of the gradual automation of the physical aspects of writing and editing, and then to the refinement ...

Terminate-and-stay-resident
A terminate-and-stay-resident program (commonly TSR) is a computer program running under DOS that uses a system call to return control to DOS as though it has finished, but remains in computer memory so it can be reactivated later. This technique partially overcame DOS's limitation of executing only one program, or task (computing), task, at a time. TSRs are used only in DOS, not in Microsoft Windows, Windows. Some TSRs are utility software that a computer user might call up several times a day, while working in another program, by using a keyboard shortcut, hotkey. Borland Sidekick was an early and popular example of this type. Others serve as device drivers for computer hardware, hardware that the operating system does not directly support. Use Normally DOS can run only one program at a time. When a program finishes, it returns control to DOS using the system call of the DOS API. The memory and system resources used are then marked as unused. This makes it impossible to restar ...

Screenplay
A screenplay, or script, is a written work produced for a film, television show (also known as a '' teleplay''), or video game by screenwriters (cf. ''stage play''). Screenplays can be original works or adaptations from existing pieces of writing. A screenplay is a form of narration in which the movements, actions, expressions and dialogue of the characters are described in a certain format. Visual or cinematographic cues may be given, as well as scene descriptions and scene changes. History In the early silent era, before the turn of the 20th century, "scripts" for films in the United States were usually a synopsis of a film of around one paragraph and sometimes as short as one sentence.Andrew Kenneth Gay"History of scripting and the screenplay"at Screenplayology: An Online Center for Screenplay Studies. Retrieved 15 December 2021. Shortly thereafter, as films grew in length and complexity, film scenarios (also called "treatments" or "synopses"Steven Maras. ''Screenwri ...

SmartKey
SmartKey was the first macro processing program of its type, and the first terminate-and-stay-resident program for PCs and CP/M microcomputers, their eight bit predecessors. Smartkey's "keyboard definitions" were first used with the early word-processing program WordStar for such things as changing margins of screenplays. Thousands of other uses were made for the program. SmartKey was originally written by Nick Hammond, an admiral in the Royal Australian Navy, and originally published by Software Research Technologies, founded by Stan Brin and Reid H. Griffin. SmartKey received two Editor's Choice awards from ''PC Magazine ''PC Magazine'' (shortened as ''PCMag'') is an American computer magazine published by Ziff Davis. A print edition was published from 1982 to January 2009. Publication of online editions started in late 1994 and continues .

Macro Recorder
A macro recorder is software that records macros for playback at a later time. The main advantage of using a macro recorder is that it allows a user to easily perform complex operations much faster and with less effort without requiring custom computer programming or scripting. Built-in macro recorders Most word processors, text editors, and other office programs have a built-in macro recorder to automate the user's actions. Standalone macro recorders Not all software comes with a built-in macro recorder. A standalone macro-recorder program allows a user to "record" mouse and keyboard functions for "playback" at a later time. This allows automating any activity in any software application: from copy-pasting spreadsheet data to operating system maintenance actions. Most macro recorders do not attempt to analyze or interpret what the user did when the macro was recorded. This can cause problems when trying to play back a macro if the user's desktop environment has changed. F ...
