'''Extended Binary Coded Decimal Interchange Code''' (usually referred to by its acronym, '''EBCDIC''') is an encoding for various glyphs (written forms such as letters, numbers, etc) into 8-[[bit]] numeric form.

It was devised by [[International Business Machines|IBM]] for use in the [[IBM System/360]] line of computers. With the success of System/360, and the creation of many [[plug-compatible]] [[peripheral]]s, etc, for it, it became widespread. It has since been mostly replaced by [[ASCII]].

The supported character set includes not only numbers, letters (upper- and lower-case) but also punctuation, and a few other special-purpose characters, like '*', '=', etc. It also does include non-printing characters used for control of printing terminals - tab, line feed, carriage return, etc.

It did not include quite a few others that ASCII has made popular - '@', '#', '^', '|', etc; this was a source of problems later, in trying to move [[programming language]]s that used them to IBM machines. These have been added later in various extensions, but support is not universal.

It also did not assign all alphabetic characters to a single range, which meant that simple tests like ''((c >= 'A') && (c <= 'Z'))'' could return 'true' when fed some non-alphabetic characters.
