EBCDIC
EBCDIC (Fully, "Extended Binary Coded Decimal Interchange Code") is a character encoding used on IBM mainframes and AS/400s. It is descended from punched cards.
Outside of such IBM systems, ASCII (and its decendants such as Unicode) are normally used instead; EBCDIC is generalliy considered an anachronism.
There are a number of different versions of EBCDIC, customised for different countries.
