EBCDIC
Extended Binary-Coded Decimal Interchange Code (EBCDIC) is an eight-bit character encoding used today, primarily in IBM mainframe and midrange systems, as well as Fujitsu, Siemens, Bull, Unisys. . You can save up to 256 different symbols, but the EBCDIC encoding has been in many versions, different for different countries. The alternative ASCII system uses 7 bits and encodes 128 characters with numbers 0-127. ASCII extensions, such as CP852, CP1250, ISO-8859, use 8-bit and code-numbers 128-255 assign new characters.
A single character is written in 8 bits divided into two parts. The first 4 bits, called a zone, denote the group to which the character belongs, while the last 4 bits, called a number, identify the particular character.
The table shows the character codes in the CCSID 500, which is an EBCDIC variant. Characters 0x00-0x3F and 0xFF are control characters, 0x40 - space, 0x41 - unbreakable space, and 0xCA - soft link.
