EDT (Univac)
EDT is a text editor running on the Unisys VS/9 operating system using the UNIVAC Series 90 mainframe computers,''EDT Text Editor Reference Manual'', Cinnaminson, New Jersey: Unisys Corporation, 1975 and as of 2013 runs on the Fujitsu BS2000 mainframe computer and operating system. It was developed by RCA for the TSOS operating system for Spectra series mainframes. The RCA version was later sold to Sperry Univac (which later became Unisys), and was released for the VS/9 operating system. The Univac/Fujitsu EDT editor is a line-based editor, in that it does not use function keys. Unlike editors such as Teco or Emacs, the program is always in text-entry mode, similar to today's word processors. Commands are sent to the editor by typing in text in the same manner as entering regular text, but the first character of the line (other than a space) is the command symbol, which defaults to the at sign (" @"). When a line begins with an @, the remainder of the line is used as a te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Text Editor
A text editor is a type of computer program that edits plain text. An example of such program is "notepad" software (e.g. Windows Notepad). Text editors are provided with operating systems and software development packages, and can be used to change files such as configuration files, documentation files and programming language source code. Plain text and rich text There are important differences between plain text (created and edited by text editors) and rich text (such as that created by word processors or desktop publishing software). Plain text exclusively consists of character representation. Each character is represented by a fixed-length sequence of one, two, or four bytes, or as a variable-length sequence of one to four bytes, in accordance to specific character encoding conventions, such as ASCII, ISO/IEC 2022, ISO/IEC 2022, Shift JIS, UTF-8, or UTF-16. These conventions define many printable characters, but also whitespace character, non-printing characters th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Line Editor
In computing, a line editor is a text editor in which each editing command applies to one or more complete lines of text designated by the user. Line editors predate screen-based text editors and originated in an era when a computer operator typically interacted with a teleprinter (essentially a computer printer, printer with a Computer keyboard, keyboard), with no video display, and no ability to move a cursor interactively within a document. Line editors are limited to typewriter keyboard text-oriented input and output methods. Most edits are a line-at-a-time. Typing, editing, and document display do not occur simultaneously. Typically, typing does not enter text directly into the document. Instead, users modify the document text by entering these commands on a text-only terminal. Commands and text, and corresponding output from the editor, will scroll up from the bottom of the screen in the order that they are entered or printed to the screen. Although the commands typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unicode
Unicode or ''The Unicode Standard'' or TUS is a character encoding standard maintained by the Unicode Consortium designed to support the use of text in all of the world's writing systems that can be digitized. Version 16.0 defines 154,998 Character (computing), characters and 168 script (Unicode), scripts used in various ordinary, literary, academic, and technical contexts. Unicode has largely supplanted the previous environment of a myriad of incompatible character sets used within different locales and on different computer architectures. The entire repertoire of these sets, plus many additional characters, were merged into the single Unicode set. Unicode is used to encode the vast majority of text on the Internet, including most web pages, and relevant Unicode support has become a common consideration in contemporary software development. Unicode is ultimately capable of encoding more than 1.1 million characters. The Unicode character repertoire is synchronized with Univers ...

Plug-in (computing)
In computing, a plug-in (also spelled plugin) or add-in (also addin, add-on, or addon) is a software component that extends the functionality of an existing software system without requiring the system to be software build, re-built. A plug-in software feature, feature is one way that a system can be customizable. Applications support plug-ins for a variety of reasons including: * Enable third-party developers to extend an application * Support easily adding new features * Reduce the size of an application by not loading unused features * Separate source code from an application because of incompatible software licenses Examples Examples of plug-in use for various categories of applications: * Digital audio workstations and audio editing software use audio plug-ins to generate, process or analyze sound. Ardour (software), Ardour, Audacity (audio editor), Audacity, Cubase, FL Studio, Logic Pro, Logic Pro X and Pro Tools are examples of such systems. * Email clients use plug-i ...

Runoff (program)
TYPSET is an early document editor that was used with the 1964-released RUNOFF program, one of the earliest text formatting programs to see significant use. Of two earlier print/formatting programs DITTO and TJ-2, only the latter had, and introduced, text justification; RUNOFF also added pagination. The name RUNOFF, and similar names led to other formatting program implementations. By 1982, ''Runoff'' (a name not possible before lowercase letters were introduced to filenames) largely became associated with Digital Equipment Corporation and Unix computers. DEC used the terms ''VAX DSR'' and ''DSR'' to refer to ''VAX DIGITAL Standard Runoff''. History CTSS The original RUNOFF type-setting program for CTSS was written by Jerome H. Saltzer circa 1964. Bob Morris and Doug McIlroy translated that from MAD to BCPL. Morris and McIlroy then moved the BCPL version to Multics when the IBM 7094 on which CTSS ran was being shut down.

Submission
Deference (also called submission or passivity) is the condition of submitting to the espoused, legitimate influence of one's superior or superiors. Deference implies a yielding or submitting to the judgment of a recognized superior, out of respect or reverence. Deference has been studied extensively by political scientists, sociologists, and psychologists. Politics Smolenski (2005) examines deference in colonial Pennsylvania, to see how claims to political authority were made, justified, and accepted or rejected. He focuses on the "colonial speech economy," that is, the implicit rules that determined who was allowed to address whom and under what conditions, and describes how the qualities that inspired deference changed in the province from 1691 to 1764. The Quaker elite initially established a monopoly on political leadership based on what they believed to be their inherent civic virtue grounded in their religious and social class. By 1760, this view had been discredited and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ampersand
The ampersand, also known as the and sign, is the logogram , representing the grammatical conjunction, conjunction "and". It originated as a typographic ligature, ligature of the letters of the word (Latin for "and"). Etymology Traditionally in English, when spelling aloud, any letter that could also be used as a word in itself ("A", "I", and "Vocative case#English, O") was referred to by the Latin expression ('by itself'), as in "''per se'' A" or "A ''per se'' A". The character &, when used by itself as opposed to more extended forms such as ''&c.'', was similarly referred to as "and ''per se'' and". This last phrase was routinely slurred to "ampersand", and the term had entered common English usage by 1837. It has been false etymology, falsely claimed that André-Marie Ampère used the symbol in his widely read publications and that people began calling the new shape "Ampère's and". History The ampersand can be traced back to the 1st century AD and the old Roma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floating-point Number
In computing, floating-point arithmetic (FP) is arithmetic on subsets of real numbers formed by a ''significand'' (a signed sequence of a fixed number of digits in some base) multiplied by an integer power of that base. Numbers of this form are called floating-point numbers. For example, the number 2469/200 is a floating-point number in base ten with five digits: 2469/200 = 12.345 = \! \underbrace_\text \! \times \! \underbrace_\text\!\!\!\!\!\!\!\overbrace^ However, 7716/625 = 12.3456 is not a floating-point number in base ten with five digits—it needs six digits. The nearest floating-point number with only five digits is 12.346. And 1/3 = 0.3333… is not a floating-point number in base ten with any finite number of digits. In practice, most floating-point systems use base two, though base ten (decimal floating point) is also common. Floating-point arithmetic operations, such as addition and division, approximate the corresponding real number arithmetic operations ...

ISAM
Indexed Sequential Access Method (ISAM) is a method for creating, maintaining, and manipulating computer files of data so that records can be retrieved sequentially or randomly by one or more keys. Indexes of key fields are maintained to achieve fast retrieval of required file records in indexed files. IBM originally developed ISAM for mainframe computers, but implementations are available for most computer systems. The term ''ISAM'' is used for several related concepts: *The IBM ISAM product and the algorithm it employs. *A database system where an application developer directly uses an application programming interface to search indexes in order to locate records in data files. In contrast, a relational database uses a query optimizer which automatically selects indexes. *An indexing algorithm that allows both sequential and keyed access to data. Most databases use some variation of the B-tree for this purpose, although the original IBM ISAM and VSAM implementations did not d ...

Emacs
Emacs (), originally named EMACS (an acronym for "Editor Macros"), is a family of text editors that are characterized by their extensibility. The manual for the most widely used variant, GNU Emacs, describes it as "the extensible, customizable, self-documenting, real-time display editor". Development of the first Emacs began in the mid-1970s, and work on GNU Emacs, directly descended from the original, is ongoing; its latest version is , released . Emacs has over 10,000 built-in commands and its user interface allows the user to combine these commands into macro (computer science), macros to automate work. Implementations of Emacs typically feature a dialect (computing), dialect of the Lisp (programming language), Lisp programming language, allowing users and developers to write new commands and applications for the editor. Extensions have been written to, among other things, manage Dired, files, Secure Shell, remote access, Gnus, e-mail, Org-mode, outlines, multimedia, Magit, Git ...

Univac
UNIVAC (Universal Automatic Computer) was a line of electronic digital stored-program computers starting with the products of the Eckert–Mauchly Computer Corporation. Later the name was applied to a division of the Remington Rand company and successor organizations. The BINAC, built by the Eckert–Mauchly Computer Corporation, was the first general-purpose computer for commercial use, but it was not a success. The last UNIVAC-badged computer was produced in 1986. History and structure J. Presper Eckert and John Mauchly built the ENIAC (Electronic Numerical Integrator and Computer) at the University of Pennsylvania's Moore School of Electrical Engineering between 1943 and 1946. A 1946 patent rights dispute with the university led Eckert and Mauchly to depart the Moore School to form the Electronic Control Company, later renamed Eckert–Mauchly Computer Corporation (EMCC), based in Philadelphia, Pennsylvania. That company first built a computer called BINAC (BINary Automat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
