Extended Binary Coded Decimal Interchange Code is an eight-bit character encoding used mainly on IBM mainframe and IBM midrange computer operating systems. It descended from the code used with punched cards and the corresponding six-bit binary-coded decimal code used with most of IBM's computer peripherals of the late 1950s and early 1960s. It is supported by various non-IBM platforms, such as Fujitsu-Siemens' BS2000/OSD, OS-IV, MSP, and MSP-EX, the SDS Sigma series, Unisys VS/9, Unisys MCP and ICL VME.
ISO/IEC 646 is a set of ISO/IEC standards, described as Information technology — ISO 7-bit coded character set for information interchange and developed in cooperation with ASCII at least since 1964. Since its first edition in 1967 it has specified a 7-bit character code from which several national standards are derived.
In computing, a code page is a character encoding and as such it is a specific association of a set of printable characters and control characters with unique numbers. Typically each number represents the binary value in a single byte.
ISO/IEC 8859-11:2001, Information technology — 8-bit single-byte coded graphic character sets — Part 11: Latin/Thai alphabet, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 2001. It is informally referred to as Latin/Thai. It is nearly identical to the national Thai standard TIS-620 (1990). The sole difference is that ISO/IEC 8859-11 allocates non-breaking space to code 0xA0, while TIS-620 leaves it undefined.
Code page 437 is the character set of the original IBM PC. It is also known as CP437, OEM-US, OEM 437, PC-8, or DOS Latin US. The set includes all printable ASCII characters as well as some accented letters (diacritics), Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as "extended ASCII".
Code page 855 is a code page used under DOS to write Cyrillic script.
Code page 865 is a code page used under DOS in Denmark and Norway to write Nordic languages.
IBM code page 932 is one of IBM's extensions of Shift JIS. The coded character sets are JIS X 0201:1976, JIS X 0208:1983, IBM extensions and IBM extensions for IBM 1880 UDC. It is the combination of the single-byte Code page 897 and the double-byte Code page 301. Code page 301 is designed to encode the same repertoire as IBM Japanese DBCS-Host.
JIS X 0201, a Japanese Industrial Standard developed in 1969, was the first Japanese electronic character set to become widely used. It is either a 7-bit encoding or an 8-bit encoding, although the 8-bit form is dominant for modern use. The full name of this standard is 7-bit and 8-bit coded character sets for information interchange (7ビット及び8ビットの情報交換用符号化文字集合).
The National Replacement Character Set (NRCS) was a feature supported by later models of Digital's (DEC) computer terminal systems, starting with the VT200 series in 1983. NRCS allowed individual characters from one character set to be replaced by one from another set, allowing the construction of different character sets on the fly. It was used to customize the character set to different local languages, without having to change the terminal's ROM for different countries, or alternately, include many different sets in a larger ROM. Many 3rd party terminals and terminal emulators supporting VT200 codes also supported NRCS.
The programming language APL uses a number of symbols, rather than words from natural language, to identify operations, similarly to mathematical symbols. Prior to the wide adoption of Unicode, a number of special-purpose EBCDIC and non-EBCDIC code pages were used to represent the symbols required for writing APL.
BCD, also called alphanumeric BCD, alphameric BCD, BCD Interchange Code, or BCDIC, is a family of representations of numerals, uppercase Latin letters, and some special and control characters as six-bit character codes.
Code page 895 is a 7-bit character set and is Japan's national ISO 646 variant. It is the Roman set of the JIS X 0201 Japanese Standard and is variously called Japan 7-Bit Latin, JISCII, JIS Roman, JIS C6220-1969-ro, ISO646-JP or Japanese-Roman. Its ISO-IR registration number is 14.
IBM code page 949 (IBM-949) is a character encoding which has been used by IBM to represent Korean language text on computers. It is a variable-width encoding which represents the characters from the Wansung code defined by the South Korean standard KS X 1001 in a format compatible with EUC-KR, but adds IBM extensions for additional hanja, additional precomposed Hangul syllables, and user-defined characters.
BraSCII is an encoded repertoire of characters that was used in Brazil. It was used in the 1980s on several printers, in applications like Carta Certa, in video boards and it was the standard character set in the Brazilian line of MSX computers. This code page is known by Star printers as Code page 3847.
DEC Special Graphics is a 7-bit character set developed by Digital Equipment Corporation. This was used very often to draw boxes on the VT100 video terminal and the many emulators, and used by bulletin board software. The designation escape sequence ESC ( 0 switched the codes for lower-case ASCII letters to draw this set, and the sequence ESC ( B switched back. IBM calls it Code page 1090.
Code page 897 is IBM's implementation of the 8-bit form of JIS X 0201. It includes several additional graphical characters in the C0 control characters area, and the code points in question may be used as control characters or graphical characters depending on the context, similarly in concept to OEM-US, but with different graphical characters. The C0 rows are shown below.
Code page 37, known as "USA/Canada - CECP", is an EBCDIC code page used on IBM mainframes. It encodes the ISO/IEC 8859-1 repertoire of graphic characters.
IBM code page 899 is a computing code page used under DOS to type mathematical symbols. It is also used by some printers. It contains the same characters as code page 259, but in a different arrangement.
Several mutually incompatible versions of the Extended Binary Coded Decimal Interchange Code (EBCDIC) have been used to represent the Japanese language on computers, including variants defined by Hitachi, Fujitsu, IBM and others. Some are variable-width encodings, employing locking shift codes to switch between single-byte and double-byte modes. Unlike other EBCDIC locales, the lowercase basic Latin letters are often not preserved in their usual locations.
