I need to remove duplicate records but also, along with it, I need to take
the average of a field taking the values of all duplicate records. I don't
want to write a cobol program for this. Can DFSORT/SYNCSORT or any other utility
help me out with this. Here an example of what I want
Input File (The first two fields form the record key) :
USD EUR 3
USD EUR 4
USD EUR 5
USD AUD 3
USD AUD 4
Output File
USD EUR 4
USD AUD 3.5
Syntax please..... |

Here's a DFSORT job that will give you a report similar to what you're asking for. You'll need z/OS DFSORT V1R5 PTF UQ95214 or DFSORT R14 PTF UQ95213 (Dec, 2004) in order to use DFSORT's new OVERLAY function. Only DFSORT has this function, so if you don't have DFSORT, you won't be able to use it. If you do have DFSORT, but you don't have the Dec, 2004 PTF, ask your System Programmer to install it (it's free). For complete details on all of the new DFSORT and ICETOOL functions available with the Dec, 2004 PTF, see:

/*

* Multiply each number by 10 for fraction (e.g. 3*10 = 30 -> 3.0)
