EBCDIC and ASCII collating sequences

A collating sequence defines the order of characters within a coded character set or COBOL alphabet for purposes of sorting, merging, and comparing data and for processing files with indexed organization.

The ascending collating sequences for both the single-byte EBCDIC (Extended Binary Coded Decimal Interchange Code) and single-byte ASCII (American National Standard Code for Information Interchange) character sets are shown in this appendix. The collating sequence is defined by the ordinal number of characters in the character set, relative to 1.

The symbols and associated meanings shown for the EBCDIC collating sequence are those defined in the EBCDIC code page defined with CCSID 1140. Symbols and meanings can vary for other EBCDIC code pages, but the collating sequence is unchanged.
