扩展二.十进制交换码

EBCDIC \EBCDIC\ ([e^]b"s[e^]*d[i^]k`), n. [acronym from Extended
Binary Coded Decimal Interchange Code.] (Computers)
a 8-bit code for representing alphanumerical information in a
digital information storage medium. It was used expecially on
IBM mainframes, and differed substantially from the ASCII
code. [acronym]
[PJC]

{Extended Binary Coded Decimal Interchange Code}

Extended Binary-Coded Decimal Interchange Code

EBCDIC: /eb´sdik/, /eb´see`dik/, /eb´kdik/, 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-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. See also
fear and loathing.
