Extended Binary Coded Decimal Interchange Code

from Wikipedia, the free encyclopedia

The Extended Binary Coded Decimal Interchange Code ( EBCDIC , analogously "extended exchange code for binary coded decimal digits") is an 8-bit character coding developed by IBM , in which, however, not all code words are used. The EBCDIC arose from the older Binary Coded Decimal Interchange Code ( BCDIC ), which in turn is based on the 4-bit code BCD ( Binary Coded Decimal ).

EBCDIC is used almost exclusively on mainframes . The EBCDIC code page is available in various variants. The historical connection with the 80-character punched card coding from IBM can be seen, in which the letters A – I, J – R and S – Z use positions 1 to 9 or 2 to 9 in the numerical zone. One consequence of this is that - in contrast to the ASCII character set - the letters A – Z do not follow one another without gaps, which makes alphabetical sorting more complicated.

Similar to the way the Unicode Transformation Format UTF-8 represents an encoding of Unicode while retaining the encoding of the ASCII character set, there is a Unicode encoding that is based on EBCDIC. This format is called UTF-EBCDIC .

EBCDIC variant EBCDIC.DF.03-DRV (CCSN: EDF03DRV)

EBCDIC.DF.03-DRV or CCSN: EDF03DRV is a variant of the EBCDIC code that is used on Fujitsu mainframes under the BS2000 / OSD operating system to display the German character set. This variant differs from other EBCDIC variants especially in the definition of German umlauts.

  • 40 hex : space

Another special feature of this character set is the double assignment of characters at the positions:

  • 4F hex : |orö
  • 7C hex : @or§
  • BB hex : [orÄ
  • BC hex : \orÖ
  • BD hex : ]orÜ
  • FB hex : {orä
  • FD hex : }orü
  • FF hex : ~orß

The representation on BS2000 / OSD is only differentiated by the hardware used or the fonts used.

Control characters

The first 64 characters from 00 hex to 3F hex define control characters and are identical for all EBCDIC code pages.

Some control characters have changed their meaning since the early versions of EBCDIC.

  • 04 hex was assigned a character called PF( Punch Off , "Lochung aus") in the first EBCDIC version from 1964 , later it became ST( String Terminator , "End of the string"), and today (2007) it is SEL( Select , "select"), for which there is no equivalent in the ASCII code.
  • 06 hex is today (2007) with RNL( Required New Line , "required new line"). Originally it was assigned with LC( Lower Case , "lower case letters") and now also with SSA( System Status Available , " System Status Available ").
  • 08 hex is now occupied with GE( Graphic Escape , "Switching to graphic mode"). Originally it was occupied with EPA( End of Protected Area , "end of the protected area").
  • 09 hex is now occupied with SPS( Superscript , "superscript"). Originally it was occupied with RLF( reverse line feed , "reverse line feed").
  • Today, 0A hex is assigned RPT( Repeat , "Repeat"). Originally it was assigned SMM( Start of Manual Message , "Beginning of a manual message").
  • 13 hex is now occupied with DC3( Device Control 3 , " Device Control Code 3"). It was originally marked with TM( Top Margin , "upper margin").
  • 14 hex is now occupied with "RES / ENP" ( Restore / Enable Presentation , "Restore / activate display"). In the meantime, it was also used OSCfor the Operating System Command .
  • Today, 17 hex is assigned POC( program operator communication , "communication with program operator "). Originally it was IL( Idle ) and now also ESA( End Selected Area , “End of the selected area”).
  • 1A hex is occupied today with UBS( Unit backspace , "one unit back"). Originally it was assigned CC( cursor control , "control of the cursor").

The abbreviation CU1stands for "Customer Use", ie a freely usable control character.

The control characters IFS( Interchange File Separator ) IGS( Interchange Group Separator ) IRS( Interchange Record Separator ) and IUS( Interchange Unit Separator ) are separators that the ASCII control character FS, GS, RSand UScorrespond. ITB( Intermediate Transmission Block , " intermediate transmission block") is another name for IUS.
