EBCDIC Character Codes

EBCDIC, Extended Binary Coded Decimal Information Code, is only rarely encountered; it is only used on IBM mainframes. A lucky person never comes across it.

EBCDIC is an Eight-bit code, but only 95 of the 256 possible character codes are used. Note that EBCDIC codes do not fall into logical blocks like ASCII codes. Under ASCII, the test (c>='a' && c<='z') is a complete test for lower case letters; the same kind of test exists for capital letters and digits. Nothing of this sort is possible with EBCDIC. Also, EBCDIC did not have square brackets []; on some equipment [ was hexadecimal code AD and ] was BD, this was not "regular issue" EBCDIC.
