Extended Binary Coded Decimal Interchange Code
/eb's*-dik/, /eb'see‘dik/, /eb'k*-dik/, /ee‘bik'dik‘/, /*-bik'dik‘/ (EBCDIC) A proprietary 8-bit character set used on IBM dinosaurs, the AS/400, and {e-Server}.
EBCDIC is an extension to 8 bits of BCDIC (Binary Coded Decimal Interchange Code), an earlier 6-bit character set used on IBM computers. EBCDIC was [first?] used on the successful System/360, anounced on 1964-04-07, and survived for many years despite the almost universal adoption of ASCII elsewhere. Was this concern for backward compatibility or, as many believe, a marketing strategy to lock in IBM customers?
IBM created 57 national EBCDIC character sets and an International Reference Version (IRV) based on {ISO 646} (and hence ASCII compatible). Documentation on these was not easily accessible making international exchange of data even between IBM mainframes a tricky task.
US EBCDIC uses more or less the same characters as ASCII
