The first standard for C was published by ANSI.

In 1983, the American National Standards Institute formed a committee, X3J11, to establish a standard specification of C. After a long and arduous process, the standard was completed in 1989 and ratified as ANSI X3. 159-1989 " Programming Language C ." This version of the language is often referred to as " ANSI C ", or sometimes " C89 " ( to distinguish it from C99 ).

In March 2000, ANSI adopted the ISO / IEC 9899: 1999 standard.

Most of the C code being written nowadays is based on ANSI C. Any program written only in standard C and without any hardware dependent assumptions is virtually guaranteed to compile correctly on any platform with a conforming C implementation.

To mitigate the differences between K & R C and the ANSI C standard, the (" standard c ") macro can be used to split code into ANSI and K & R sections.

As time progressed, most terminal programs began using the ANSI standard, but could use their native character set if it was available.

American National Standards Institute / American Society of Safety Engineers standard ANSI Z359. 1-2007 Safety Requirement for Personal Fall Arrest Systems, Subsystems and Components, section 3. 2. 1. 4 ( for snap hooks and carabiners ) is a voluntary consensus standard.

Before there was an official standard for C, many users and implementors relied on an informal specification contained in a book by Ritchie and Brian Kernighan ; that version is generally referred to as " K & R " C. In 1989 the American National Standards Institute published a standard for C ( generally called " ANSI C " or " C89 ").

Common Lisp ( CL ) is a dialect of the Lisp programming language, published in ANSI standard document ANSI INCITS 226-1994 ( R2004 ), ( formerly X3. 226-1994 ( R1999 )).

From the ANSI Common Lisp standard the Common Lisp HyperSpec has been derived for use with web browsers.

The American National Standards Institute ( ANSI ), Standard 1100, defines the requirements of meeting the ANSI standard for being a certifying organization.

In an attempt to overcome the problem of incompatibility between different versions of COBOL, the American National Standards Institute ( ANSI ) developed a standard form of the language in 1968.

In 1985, ANSI published still another revised version that had new features not in the 1974 standard, most notably structured language constructs (" scope terminators "), including,,, etc.

The final approved ISO standard ( adopted as an ANSI standard by INCITS ) was approved and made available in 2002.

The corresponding American standard is ANSI Z535, which is incompatible with the ISO standard.

ANSI standard Z535. 1 – 1998 states how safety orange is defined in the following notation systems:

ASCII was subsequently updated as USASI X3. 4-1967, then USASI X3. 4-1968, ANSI X3. 4-1977, and finally, ANSI X3. 4-1986 ( the first two are occasionally retronamed ANSI X3. 4-1967, and ANSI X3. 4-1968 ).

Asynchronous Transfer Mode ( ATM ) is, according to the ATM Forum, " a telecommunications concept defined by ANSI and ITU ( formerly CCITT ) standards for carriage of a complete range of user traffic, including voice, data, and video signals ," and is designed to unify telecommunication and computer networks.

The ANSI / NISO Z39. 19 Standard of 2005 defines guidelines and conventions for the format, construction, testing, maintenance, and management of monolingual controlled vocabularies including lists, synonym rings, taxonomies, and thesauruses.

The modern ANSI / TIA-968-B specification ( August 2009 ) defines 1 REN as an impedance of 7000Ω at 20Hz ( type A ), or 8000Ω from 15Hz to 68Hz ( type B ).

The earliest standard that defines the algorithm ( ANS X9. 52, published in 1998 ) describes it as the " Triple Data Encryption Algorithm ( TDEA )" — i. e. three operations of the Data Encryption Algorithm specified in ANSI X3. 92 — and does not use the terms " Triple DES " or " DES " at all.

The American National Standard for Industrial Robots and Robot Systems — Safety Requirements ( ANSI / RIA R15. 06-1999 ) defines a singularity as “ a condition caused by the collinear alignment of two or more robot axes resulting in unpredictable robot motion and velocities .” It is most common in robot arms that utilize a “ triple-roll wrist ”.

It is probable that 16VSB has been replaced by ANSI / SCTE 07 2006: Digital Transmission Standard For Cable Television, a cable standard that defines 64QAM and 256QAM transmission for digital cable.

American National Standards Institute ( ANSI ) standard ANSI X3. 64 defines a standard set of escape sequences that can be used to drive terminals to create TUIs ( see ANSI escape code ).

In ANSI X. 923 bytes filled with zeros ( 0 )' s are padded and the last byte defines the padding boundaries or the number of padded bytes.

The standard Safe Practices for Motor Vehicle Operations, ANSI / ASSE Z15. 1, defines defensive driving as " driving to save lives, time, and money, in spite of the conditions around you and the actions of others.

ANSI T1. 413 is a technical standard that defines the requirements for the single asymmetric digital subscriber line ( ADSL ) for the interface between the telecommunications network and the customer installation in terms of their interaction and electrical characteristics.

and ANSI / ASME B89. 1. 9M, which defines both absolute deviations from nominal dimensions and parallelism limits as criteria for grade determination.

Most of the information was displayed using ordinary ASCII text or ANSI art, though some BBSes experimented with higher resolution visual formats such as the innovative but obscure Remote Imaging Protocol.

Wide Area Information Servers or WAIS is a client – server text searching system that uses the ANSI Standard Z39. 50 Information Retrieval Service Definition and Protocol Specifications for Library Applications " ( Z39. 50: 1988 ) to search index databases on remote computers.

Most Windows text files use a form of ANSI, OEM or Unicode encoding.

In terms of video, the text display added 32 unique character symbols called “ MouseText ” which, when placed side by side, could display simplistic looking icons, windows and menus to recreate a graphical user interface completely out of text, similar in concept to IBM ANSI or PETSCII.

Before the advent of ANSI C, the first edition of the text served as the de facto standard of the language for writers of C compilers.

The QBasic game uses the standard 80x25 text screen to emulate an 80x50 grid by making clever use of foreground and background colors, and the ANSI characters for full blocks and half-height blocks.

On IBM Personal Computers and compatibles, the Basic Input Output System ( BIOS ) and DOS system calls provide a way to write text on the screen, and the ANSI. SYS driver could process standard ANSI escape sequences.

Using ANSI escape code SGR sequences, compatible terminals can print out colored text:

Similar to the constraints of ASCII and ANSI art, the coder and artist both must take into consideration the limitations presented by text mode: a base resolution of 80 × 25 " blocks " and a mere 16 fixed colors by default.

PabloDraw is a cross-platform text editor designed for creating ANSI and ASCII art, similar to that of its DOS-based predecessors ; ACiDDraw ( 1994 ) and TheDraw ( 1986 ).

This editor is capable of handling most standard text mode formats such as ANSI, ASCII and Binary (< tt >. BIN </ tt >).

ANSI art also contains special ANSI escape sequences that color text with the 16 foreground and 8 background colours offered by ANSI. SYS, an MS-DOS device driver loosely based upon the ANSI X3. 64 standard for text terminals.

ANSI art and text files which incorporate ANSI codes carry the de facto < tt >. ANS </ tt > file extension.
