I understand that we are sorting first from 12 th pos and taking 3 bytes,then 6 th pos and taking 5 bytes and then 5 th pos and taking 1 byte for sorting in ascending order.But i am unable to understand the Outrec Fields.I know that (1,4) means we are forming the first four bytes but i am unable to understand what does ,12 do in extension.

OUTREC FIELDS=(1,4,12)
yadav2005,
I am guessing that you input file is a variable Blocked (VB) file. For VB files you don't have to mention the length.
The above outrec copies the first 4 bytes of RDW and then copies the contents from pos 12 to the end of each record. Since it is a variable block file we don't mention the length as the length of each record varies.
For variable block files SORT automatically copies the record till the end.
You are correct.My input dataset is a VB File and i have clearly understand by the explanation given by you.Now when i see the SORTOUT output VB dataset and compare with the SORTIN VB Dataset it has made me clear.
If you're not familiar with DFSORT and DFSORT's ICETOOL, I'd suggest reading through "z/OS DFSORT: Getting Started". It's an excellent tutorial, with lots of examples, that will show you how to use DFSORT, DFSORT's ICETOOL and DFSORT Symbols. You can access it online, along with all of the other DFSORT books, from:
