I started playing with new DFSort PTF yesterday and I have few questions on that.
1) For subtaskn, is it really a Parallel processing? Meaning does DFSort actually initiates 2 parallel task to save some time on processing or these are being processed one by one? If it does initiate 2 parallel task, Is there a way to check that?
2) Although I have tried this and got error but in REFORMAT statement,why are we not allowed to insert filler char?
In the Example below, I am trying to insert '-' between the fields but it gave me error. I do understand that we can add fields in BUILD statement after REFORMAT but I was curious to know what was the purpose behind not allowing?

I can't discuss in detail what we're doing. But yes, the tasks run in parallel.
To keep the REFORMAT statement simple, we just allow the fields from the two input files (and the ? indicator). If you want to add constants or anything else, you can either do that before the join (with JNFxCNTL statements) or after the join (with SYSIN statements). _________________ Frank Yaeger - DFSORT Development Team (IBM)
