  ASCII and EBCDIC compared - Dynamoo.com
EBCDIC uses the full 8 bits available to it, so parity checking cannot be used on an 8 bit system.
There are four main blocks in the EBCDIC code page: 0000 0000 to 0011 1111 is reserved for control characters; 0100 0000 to 0111 1111 are for punctuation; 1000 0000 to 1011 1111 for lowercase characters and 1100 0000 to 1111 1111 for uppercase characters and numbers.
EBCDIC also has dozens of different variants, some of which are essentially incompatible with other variants of EBCDIC.

  What is EBCDIC?
EBCDIC, Extended Binary Coded Decimal Interchange Code, was developed in 1963 by IBM as an extension to the older Binary Coded Decimal (BCD) standard.
Each EBCDIC variant is known as a codepage, identified by its Coded Character Set Identifier, or CCSID.
EBCDIC codepages have been created for a number of major writing scripts, including such complex ones as Chinese, Korean and Japanese.

 TS-DOC: TS-642 - Reading EBCDIC Files on ASCII Systems
This document will focus on reading EBCDIC files using SAS running on a PC which is one of the more commonly asked questions in Technical Support.
EBCDIC is the character encoding system of mainframes and ASCII is the encoding system on other machines such as VAX, PC, UNIX, and Macintosh.
As long as EBCDIC files stay on mainframes and ASCII files on PCs, etc. there is no difficulty reading or writing data or understanding what's in the file.

Thus the 65 Unicode characters corresponding to the 65 ISO/IEC 6429 control characters and the 95 characters corresponding to the 95 ASCII graphic characters (the G0 set) are represented in the I8-sequence as single bytes.
Positions assigned to EBCDIC controls, the invariant graphic characters and the variant graphics are shown in Table B.1.
If transparency to EBCDIC invariance and controls is needed also in the normalized form, then Unicode cannot be directly used for normalization.

 The Apache EBCDIC Port
EBCDIC stands for Extended Binary-Coded-Decimal Interchange Code and is the codeset used on mainframe machines, in contrast to ASCII which is ubiquitous on almost all micro computers today.
The possibility to translate between ASCII and EBCDIC at the socket level (on BS2000 POSIX, there is a socket option which supports this) was intentionally not chosen, because the byte stream at the HTTP protocol level consists of a mixture of protocol related strings and non-protocol related raw file data.
All header processing is done in the native EBCDIC format; the server then determines, based on the type of document being served, whether the document body (except for the chunking information, of course) is in ASCII already or must be converted from EBCDIC.

THE EBCDIC CHIMERA A year ago, Joel Winett Published RFC #183, containing the results of his careful research into just what EBCDIC really means.
It is clear from RFC #183 that EBCDIC consists of a standard ("basic") set of characters, combined with a number of overlapping ad-hoc character happenings.
We could (and did) take the view that all CCN users are concerned only with writing and executing normal 360 programs using EBCDIC and that they would enter one of the maverick ASCII graphics only in error.

 EBCDIC, ASCII and Numbers
EBCDIC and ASCII are very common terms used when describing files, but when numeric fields are involved conversion is not straightforward.
EBCDIC and ASCII are both ways of mapping computer codes to characters and numbers, as well as other symbols typically used in writing.
Typically, from EBCDIC to ASCII, and numeric fields, packed decimal fields etc are converted to ASCII strings.

 EBCDIC Summary
EBCDIC is a method of assigning binary number values to characters (alphabetic, numeric, and special characters such as punctuation and control characters).
EBCDIC was the code for text files used in IBM's OS/390 operating system for its S/390 servers, and continues to be used by corporations for their legacy applications and data (those that have been inherited earlier generations of technology).
EBCDIC was devised in 1963 and 1964 by IBM and was announced with the release of the IBM System/360 line of mainframe computers.

 EBCDIC Extended Binary-Coded Decimal Interchange Code 8 Bits   (Site not responding. Last check: 2007-11-02)
Mapping between EBCDIC and ASCII was mostly straightforward, except for a few characters: for example, EBCDIC lacked caret, so its "hooked overline" character was substituted.
EBCDIC takes up eight bits, which are divided in two pieces.
The first four bits are called the "zone" and represent the catagory of the character, whereas the last four bits are the called the "digit" and identify the specific character.

 Section 5. IBM AND EBCDIC   (Site not responding. Last check: 2007-11-02)
EBCDIC (Extended Binary Coded Decimal Interchange Code) was a further development of older codes like BCDIC, BCD and back to Hollerith.
Should one use the numerical value of a byte as the base of a collating sequence, then the letters precede the digits, and the small letters the capital letters.
EBCDIC has been, up to the late 70s, the most frequently applied character code, next to which ASCII only had a marginal existence.

 EBCDIC, ASCII, BAUDOT, BCD, Octal, Hex, Binary, Morse Code and Braille
Packed decimal is a method of storing integers on IBM mainframes in a format that stores the number using an odd number of base 10 digits and a final sign character.
There are instructions to convert packed decimal numbers to binary, and to convert packed decimal numbers to human readable EBCDIC numbers which is the default character set on IBM mainframes.
Packed decimal numbers can be easily read in a hex memory dump without the need to convert the number from binary to base 10 because the packed decimal number is stored as a base 10 number.

 EBCDIC Character Codes
EBCDIC, Extended Binary Coded Decimal Information Code, is only rarely encountered; it is only used on IBM mainframes.
EBCDIC is an Eight-bit code, but only 95 of the 256 possible character codes are used.
Also, EBCDIC did not have square brackets []; on some equipment [ was hexadecimal code AD and ] was BD, this was not "regular issue" EBCDIC.

 Perl and EBCDIC? - The Perl Journal, Winter 1997
In contrast, EBCDIC does not have the alphabet in a stepwise continuous sequence - there are gaps - but both the upper and lower case alphabets are numerically sortable just like ASCII.
EBCDIC is of special interest to me because I work on an IBM OS/390 computer running OpenEdition, which internally uses EBCDIC.(The OpenEdition environment has been described as Unix on a mainframe; MVS OpenEdition comes with a POSIX shell, an ANSI C/C++ library and compilers, Berkeley style sockets, a hierarchical file system, and a web server.
The gaps in EBCDIC are a result of the way the code was laid out to fit on punch cards: groups of 9, 9, and 8 characters separated by 16 or 17 characters.

 EBCDIC   (Site not responding. Last check: 2007-11-02)
EBCDIC is an 8 bit code that is used in mini-computers and mainframes to represent all numbers, letters, and special characters.
There must be four bits used for both the zone and the digit, so the 8, 4, and 2 positions all have a zero in them.
If you are to give the EBCDIC for a two digit number, for example 27, you would have to hit two keys on the keyboard to enter 27 into the computer.
