:вЂЉ66,вЂЉ245 There was some debate at the time whether there should be more control characters rather than the lowercase alphabet.

With the other special characters and control codes filled in, ASCII was published as ASA X3.4-1963, leaving 28 code positions without any assigned meaning, reserved for future standardization, and one unassigned control code. The ASA later became the United States of America Standards Institute (USASI), :вЂЉ211 and ultimately became the American National Standards Institute (ANSI). The American Standard Code for Information Interchange (ASCII) was developed under the auspices of a committee of the American Standards Association (ASA), called the X3 committee, by its X3.2 (later X3L2) subcommittee, and later by that subcommittee's X3.2.4 working group (now INCITS). Control pictures of equivalent controls are shown where they exist, or a grey dot otherwise. In addition, the original ASCII specification included 33 non-printing control codes which originated with Teletype machines most of these are now obsolete, although a few are still commonly used, such as the carriage return, line feed, and tab codes.ДЇor example, lowercase i would be represented in the ASCII encoding by binary 1101001 = hexadecimal 69 ( i is the ninth letter) = decimal 105.ДЄSCII (1963). Ninety-five of the encoded characters are printable: these include the digits 0 to 9, lowercase letters a to z, uppercase letters A to Z, and punctuation symbols. Originally based on the English alphabet, ASCII encodes 128 specified characters into seven-bit integers as shown by the ASCII chart above. That document was formally elevated to an Internet Standard in 2015. The use of ASCII format for Network Interchange was described in 1969. Compared to earlier telegraph codes, the proposed Bell code and ASCII were both ordered for more convenient sorting (i.e., alphabetization) of lists and added features for devices other than teleprinters.

The first edition of the standard was published in 1963, underwent a major revision during 1967, and experienced its most recent update during 1986.

Work on the ASCII standard began in May 1961, with the first meeting of the American Standards Association's (ASA) (now the American National Standards Institute or ANSI) X3.2 subcommittee. Its first commercial use was as a seven- bit teleprinter code promoted by Bell data services.
