drop duplicate records from said file. Sort would work fine if I knew the
correct key sequence. This information is not imediately available. The file
needs to retain its input sequence. Duplicates are
Thanks Frank,
No DFSORT and NO ICETools here. DFSORT would have been great. Regular sort
will not work without a Sort or merge statement.
The file characteristics are:
Organization . . . : PS
Record format . . . : FB
Record length . . . : 320
Block size . . . . : 27840
Actually I thought of a much better way to do this with DFSORT's ICETOOL
given that you say all of the duplicates are grouped together.
This version only requires one copy pass rather than two sort passes.
//S1EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN DD *
