'''Extended Binary Coded Decimal Interchange Code''' ('''EBCDIC''') is an 8-[[bit]] [[character encoding]] ([[code page]]) used on [[IBM mainframe]] [[operating systems]] such as [[z/OS]], [[OS/390]], [[VM (operating system)|VM]] and [[VSE (operating system)|VSE]], as well as [[IBM]] [[midrange computer]] operating systems such as [[OS/400]] and [[i5/OS]] (see also [[Binary Coded Decimal#IBM and BCD|Binary Coded Decimal]]). It is also employed on various non-IBM platforms such as [[Fujitsu]]-[[Siemens AG|Siemens]]' [[BS2000|BS2000/OSD]], [[Hewlett-Packard|HP]] [[MPE/iX]], and [[Unisys]] [[MCP (Burroughs Large Systems)|MCP]]. It descended from [[punched card]]s and the corresponding six bit [[binary-coded decimal]] code that most of IBM's computer peripherals of the late 1950s and early 1960s used. 

== History ==
EBCDIC was devised in 1963 and 1964 by [[IBM]] and was announced with the release of the [[System/360|IBM System/360]] line of mainframe [[computer]]s. It was created to extend the [[Binary-coded decimal#IBM and BCD|Binary-Coded Decimal]] encoding that existed at the time. It is an 8-bit character encoding, in contrast to, and developed separately from, the 7-bit [[American Standard Code for Information Interchange|ASCII]] encoding scheme.

Interestingly, IBM was a chief proponent of the ASCII standardization committee. However, IBM did not have time to prepare ASCII peripherals (such as card punch machines) to ship with its System/360 computers, so the company settled on EBCDIC at the time. The System/360 became wildly successful, and thus so did EBCDIC.

All IBM mainframe [[peripheral]]s and [[operating system]]s (except [[Linux on zSeries]] or [[iSeries]]) use EBCDIC as their inherent encoding.<ref name="ibmebcdic">{{Kilde www

Many hardware peripherals provide translation as well and modern mainframes (such as IBM [[zSeries]]) include processor instructions, at the hardware level, to accelerate translation between character sets.

At the time it was devised, EBCDIC made it relatively easy to enter data into a computer with [[Punched cards| punch cards]]. Since [[Punched cards| punch cards]] are no longer used on mainframes, EBCDIC is used in modern mainframes solely for backwards compatibility. It has no real technical advantage over ASCII-based code pages such as the [[ISO-8859]] series or [[Unicode]]. There are some technical niceties in each, e.g., ASCII and EBCDIC both have one bit which indicates upper or lower case. But there are some aspects of EBCDIC which make it much less pleasant to work with than ASCII (such as a non-contiguous alphabet).  As with single-byte [[extended ASCII]] codepages, most EBCDIC codepages only allow up to 2 languages (English and one other language) to be used in a [[database]] or text file.

Where true support for multilingual text is desired, a system supporting far more characters is needed. Generally this is done with some form of Unicode support. There is an EBCDIC [[Unicode Transformation Format]] called [[UTF-EBCDIC]] proposed by the Unicode consortium, but it is not intended to be used in open interchange environments and, even on EBCDIC-based systems, it is almost never used. IBM mainframes support [[UTF-16]], but they do not support UTF-EBCDIC natively.

Arabic EBCDIC versions are typically in presentation order, in left to right order as displayed by an older mainframe or line printer, rather than in the right to left logical order used by modern encodings such as Unicode.

== Codepage layout ==
The table below is derived from [[EBCDIC 500|CCSID 500]], one of the code page variants of EBCDIC, showing only the basic (English) EBCDIC characters. Characters 00–3F and FF are [[control character|control]]s, 40 is [[space character|space]], 41 is [[no-break space]] (''RSP'': "Required Space"), E1 is numeric space (''NSP'': "Numeric Space"), and CA is [[soft hyphen]]. Characters are shown with their equivalent [[Unicode]] codes. Invariant alphanumeric, punctuation, and control characters common to all EBCDIC code pages are shown in color. Unassigned codes are typically filled with international or region-specific characters in the various EBCDIC [[code page]] variants.

== Criticism and humor ==
[[Open source software]] advocate and hacker [[Eric S. Raymond]] writes in his ''[[Jargon File]]'' that EBCDIC was almost universally loathed by early hackers and programmers because of its multitude of different versions, none of which resembled the other versions, and that IBM produced it in direct competition with the already-established ASCII.

The Jargon file 4.4.7 gives the following definition:
{{cquote2|quotetext=EBCDIC: /eb´s@·dik/, /eb´see`dik/, /eb´k@·dik/, n.
[abbreviation, Extended Binary Coded Decimal Interchange Code] An alleged character set used on IBM dinosaurs. It exists in at least six mutually incompatible versions,  all featuring such delights as non-contiguous letter sequences and the absence of several ASCII punctuation characters fairly important for modern computer languages (exactly which characters are absent varies according to which version of EBCDIC you're looking at). IBM adapted EBCDIC from punched card code in the early 1960s and promulgated it as a customer-control tactic (see ''[[connector conspiracy]]''), spurning the already established ASCII standard. Today, IBM claims to be an [[open system (computing)|open-systems]] company, but IBM's own description of the EBCDIC variants and how to convert between them is still internally classified top-secret, burn-before-reading. Hackers blanch at the very name of EBCDIC and consider it a manifestation of purest evil. 
|quotesource=The Jargon file 4.4.7}}
<!-- Claims to be public domain: [http://catb.org/jargon/quoting.html] -->

Another popular complaint is that the EBCDIC alphabetic characters follow an archaic punch card encoding rather than a linear ordering like ASCII. The upshot of this is that incrementing the character code for "I" does not produce the code for "J", and likewise there is a gap between the codes for "R" and "S". Thus programming a simple [[program loop|control loop]] to cycle through only the alphabetic characters is problematic.

These incompatibilities were also the source of many jokes. A popular one went: 
:''Professor: "So the American government went to IBM to come up with an [[data encryption|encryption]] standard, and they came up with&mdash;"<br/>Student: "EBCDIC!"''
