Abbreviated EBCDIC; pronounced "eb-se-dic." EBCDIC is the character set commonly used on large IBM mainframe computers, most IBM minicomputers, and computers from many other manufacturers.
It is an 8-bit code, allowing 256 different characters (see Appendix D). Unlike ASCII, the placement of the letters of the alphabet in EBCDIC is discontinuous. Also, there is no direct character-to-character match when converting from EBCDIC to ASCII; some characters exist in one set but not in the other.
