Hi ,

I want to remove duplicates from a FB file with LRECL = 12000 and to write dups into another file. My requirement is to compare whole record without sorting the file.

Could anyone please help me on this.


Thanks,
Raja

Can you run this and post the full sysout, so we can see what level of sort you have, please?

Code:
//S1 EXEC PGM=SORT
//SYSOUT   DD SYSOUT=*
//SORTIN DD *
RECORD
/*
//SORTOUT DD DUMMY
//SYSIN   DD   *
  OPTION COPY
/*

Unless the data is sorted there is no way to determine the duplicates. Moreover the 12000 is way beyond the max length of 4092 bytes that sort can handle.
