Choosing alternate collating sequences
You can sort or merge records on the EBCDIC or ASCII collating sequence, or on another
collating sequence. The default collating sequence is EBCDIC unless
you code the PROGRAM COLLATING SEQUENCE clause in
the OBJECT-COMPUTER paragraph.
About this task
To override the default
sequence, use the COLLATING SEQUENCE phrase of the SORT or MERGE statement.
You can use different collating sequences for each SORT or MERGE statement
in your program.
The PROGRAM COLLATING SEQUENCE clause
and the COLLATING SEQUENCE phrase apply only to keys
of class alphabetic or alphanumeric.
When you sort or merge an ASCII
file, you have to request the ASCII collating sequence. To do so,
code the COLLATING SEQUENCE phrase of the SORT or MERGE statement,
and define the alphabet-name as STANDARD-1 in
the SPECIAL-NAMES paragraph.
