I think you can use them. In the PDF it is specified DataSets but you can use flat file, DB also.

Yes you can use the merge stage for complex flat files.

Every stage in a parallel job works only with the virtual Data Sets associated with its links*. What's on the other end of that link is totally irrelevant, provided that the rows match the record schema.

Look at the generated osh and the score to see this happening.

* (With the single exception, naturally, of sparse lookups.)

ie., the data in Cobol file (CFF stage) that you use will also be converted into a virtual dataset before you Merge stage.
