Your question is not at all clear. Are you wanting to reverse the sequence of records (not rows -- DB2 has rows but data sets do not), or are you just wanting to swap the first and last records of the data set, or are you wanting to swap the first and last bytes of each record (and if so, are you wanting to do this for each record)?
