APPENDIX1.5.3 Procedure Division
An ASCII collated sort/merge operation can be specified in two ways:
- Through the PROGRAM COLLATING SEQUENCE clause in the OBJECT-COMPUTER
paragraph.
In this case, the ASCII collating sequence is used for nonnumeric comparisons explicitly specified in relation conditions and condition-name conditions. - Through the COLLATING SEQUENCE phrase of the SORT or MERGE statement.
In this case, only this sort/merge operation uses the ASCII collating sequence.
For this sort/merge operation, the COLLATING SEQUENCE option takes precedence over the PROGRAM COLLATING SEQUENCE clause.
If both the PROGRAM COLLATING SEQUENCE clause and the COLLATING SEQUENCE phrase are omitted (or if the one in effect specifies an EBCDIC collating sequence), the sort/merge is performed using the EBCDIC collating sequence.
