Cursor \Cur"sor\ (k?r"s?r), n. [L., a runner. See Cursitor.] Any part of a mathematical instrument that moves or slides backward and forward upon another part.
Douglas Harper's Etymology Dictionary
computer sense is 1967 extension of name for the sliding part of a slide rule or other instrument (1590s), earlier "a running messenger" (c.1300), from Latin cursor "runner," also "errand-boy," from curs-, past participle stem of currere "to run" (see current (adj.)).
n. 1 A part of any of several scientific instruments that moves back and forth to indicate a position 2 (context graphical user interface English) A moving icon or other representation of the position of the pointing device. 3 (context graphical user interface English) An indicator, often a blinking line or bar, indicating where the next insertion or other edit will take place. Also referred to as "the caret". 4 (context databases English) A reference to a row of data in a table, which moves from row to row as data is retrieved by way of it. 5 (context programming English) A design pattern in object oriented methodology in which a collection is iterated uniformly, also known as the iterator pattern. vb. (context intransitive computing English) To navigate by means of the cursor keys.
n. (computer science) indicator consisting of a movable spot of light (an icon) on a visual display; moving the cursor allows the user to point to commands or screen positions [syn: pointer]
In computer user interfaces, a cursor is an indicator used to show the current position for user interaction on a computer monitor or other display device that will respond to input from a text input or pointing device. The mouse cursor is also called a pointer, owing to its resemblance in usage to a pointing stick.
CURSOR: Programs for PET Computers was the name of an early computer-based "magazine" that was distributed on cassette from 1978 and into the early 1980s. Each issue, consisting of the cassette itself and a short newsletter including a table of contents, contained programs, utilities, and games. Produced for users of the Commodore PET, and available by subscription only, CURSOR was a forerunner of the later disk magazines ("diskmags") that came about as floppy disk drives became common, and eventually ubiquitous, in home and personal computing during the 1980s.
Ron Jeffries and Glen Fisher, of the software company The Code Works of Goleta, California, was CURSOR's publisher and editor, respectively.
Each issue came with five or six programs, preceded by a "cover page" program (which was initially a simple animation, but in later issues became more sophisticated, allowing the user to select a program to be loaded from the tape). Among programs circulated by CURSOR included rudimentary animations, such as "Dromeda", which was an adaptation of the film The Andromeda Strain; games, such as a version of the Star Trek text-based campaign game, "Twonky" (a version of Hunt the Wumpus), and "Ratrun", an early dungeon crawl-style game (only with the player as a mouse searching for a piece of cheese in a 3D maze); and simple utility programs such as spreadsheets and code-tweakers (including a utility that allowed the PET to display lower-case lettering). Initially, programs (specifically games and animations) distributed on Cursor did not have sound, as the PET did not initially have this capability. As external audio devices such as Soundware became available for PET models, sound-capable programs began to appear in Cursor; these programs were identified by an exclamation point (!) in the title. For example: "Aliens!" or "Dromeda!".
CURSOR was discontinued in the early 1980s when the PET was superseded by other platforms. In total, 30 issues of the magazine were published. Issue #30 had the date May, 1982.
In computer science, a databasecursor is a control structure that enables traversal over the records in a database. Cursors facilitate subsequent processing in conjunction with the traversal, such as retrieval, addition and removal of database records. The database cursor characteristic of traversal makes cursors akin to the programming language concept of iterator.
Cursors are used by database programmers to process individual rows returned by database system queries. Cursors enable manipulation of whole result sets at once. In this scenario, a cursor enables the rows in a result set to be processed sequentially.
In SQL procedures, a cursor makes it possible to define a result set (a set of data rows) and perform complex logic on a row by row basis. By using the same mechanics, a SQL procedure can also define a result set and return it directly to the caller of the SQL procedure or to a client application.
A cursor can be viewed as a pointer to one row in a set of rows. The cursor can only reference one row at a time, but can move to other rows of the result set as needed.
