Appendix D: Character Sets

The following charts show the ordering of characters in two widely used character sets: ASCII (American Standard Code for Information Interchange) and EBCDIC (Extended Binary Coded Decimal Interchange Code). The internal representation for each character is shown in decimal. For example, the letter A is represented internally as the integer 65 in ASCII and as 193 in EBCDIC. The space (blank) character is denoted by a "".
