EBCDIC 273

IBM code page 273 is an EBCDIC code page with the full Latin-1 character set used in IBM mainframes. It is used in Germany and Austria.

CCSID 1141 is the Euro currency update of code page/CCSID 273. In that code page, the "¤" (currency) character at code point 9F is replaced with the "€" (Euro) character.

Code page translation

Since CP 273 contains all of the standard Latin-1 characters, it is possible to translate the character codes from the CP 037 charset to ISO 8859-1 character codes, so that translation back to the CP 037 charset is an exact value-preserving round-trip conversion. Likewise, half of the control character codes can be translated into their exact ASCII equivalents. If the remaining EBCDIC-only control characters are translated (arbitrarily) into the remaining unused ASCII codes points (hex 80 to 9F) as well, the resulting translation covers all of the 256 character code points. Such a translation table is shown below:

EBCDIC

Extended Binary Coded Decimal Interchange Code (EBCDIC) is an eight-bit character encoding used mainly on IBM mainframe and IBM midrange computer operating systems. EBCDIC descended from the code used with punched cards and the corresponding six bit binary-coded decimal code used with most of IBM's computer peripherals of the late 1950s and early 1960s. It is also employed on various non-IBM platforms such as Fujitsu-Siemens' BS2000/OSD, OS-IV, MSP, and MSP-EX, and Unisys VS/9 and MCP.

History

EBCDIC /ˈɛbsᵻdɪk/ was devised in 1963 and 1964 by IBM and was announced with the release of the IBM System/360 line of mainframe computers. It is an eight-bit character encoding, in contrast to, and developed separately from, the 7-bit ASCII encoding scheme. It was created to extend the existing binary-coded decimal (BCD) interchange code, or BCDIC, which itself was devised as an efficient means of encoding the two zone and number punches on punched cards into 6 bits.

While IBM was a chief proponent of the ASCII standardization committee, the company did not have time to prepare ASCII peripherals (such as card punch machines) to ship with its System/360 computers, so the company settled on EBCDIC. The System/360 became wildly successful, and together with clones such as RCA Spectra 70, ICL System 4, and Fujitsu FACOM, thus so did EBCDIC.

EBCDIC 500

IBM code page 500 (CCSID 500) is an EBCDIC code page with full Latin-1-charset used in IBM mainframes.

CCSID 1148 is the Euro currency update of code page/CCSID 500. Byte 9F is replaced ¤ with € in that code page.

Codepage layout

Characters 00–3F and FF are controls, 40 is space, 41 is no-break space, and CA is soft hyphen. Characters are shown with their equivalent Unicode codes. Invariant alphanumeric, punctuation, and control characters are shown in color.
