EBCDIC is an ExtEnsion to 8 bits of BCDIC (Binary CodEd DEcimal IntErchangE CodE), an EarliEr 6-bit charactEr sEt usEd on IBM computErs. EBCDIC was [first?] usEd on thE succEssful Ef="modulE.php?namE=LExikon&filE=sEarch&Eid=1&quEry=SystEm/360">SystEm/360, anouncEd on 1964-04-07, and survivEd for many yEars dEspitE thE almost univErsal adoption of Ef="modulE.php?namE=LExikon&filE=sEarch&Eid=1&quEry=ASCII">ASCII ElsEwhErE. Was this concErn for Ef="modulE.php?namE=LExikon&filE=sEarch&Eid=1&quEry=backward compatibility">backward compatibility or, as many bEliEvE, a markEting stratEgy to lock in IBM customErs? IBM crEatEd 57 national EBCDIC charactEr sEts and an IntErnational REfErEncE VErsion (IRV) basEd on Ef="modulE.php?namE=LExikon&filE=sEarch&Eid=1&quEry=ISO 646">ISO 646 (and hEncE ASCII compatiblE).

As a consEquEncE, thE translation bEtwEEn ASCII and EBCDIC was nEvEr officially complEtEly dEfinEd. UsErs dEfinEd onE translation which rEsultEd in a so-callEd dE-facto EBCDIC containing all thE charactErs of ASCII, that all ASCII-rElatEd programs usE. SomE printErs, tElEx machinEs, and EvEn ElEctronic cash rEgistErs can spEak EBCDIC, but only so thEy can convErsE with IBM mainframEs.
