The OP did not specify what type of VSAM datasets are involved. If KSDS, they
are already sorted on a key value, and might be amenable to a MERGE operation
(but what about duplicate keys?). Other considerations: 1) Are all the VSAM
datasets the same type? 2) Do they all have the same RECFM and LRECL? 3) are
there any alternate indices in the set?
Based on the limited information given originally, the simplest means seems to
be IDCAMS REPRO from each VSAM dataset in turn, to a VB "flat file" coded with
DISP=MOD. Whether that output VB "flat file" might be useful is a separate
problem.
