Are you ever taken Quiz on Cobol? It is completely free-for your HELP just check out here.
The following syntax of sort has some hidden meanings.
Just I would like to share those:
Sort Filename-1 On Ascending/Descending key dataname-1 With Duplicates in Order Using filename-2 Giving filename-3
COBOL Sort The Key Points
- Here, all the files opened and closed automatically. No need to open/write explicitly.
- All these files can be sequential/Relative/Indexed
- We need to use “With Duplicates in order” if we want to keep duplicates in the same sequence
- In Using and Giving we can give multiple files
- We can give both Ascending and Descending Keys at a time
