Hi,

I have a requirement to identify the duplicates in a flat file. I know SUM FIELDS=NONE will eliminate the duplicates, but I would like to retain the duplicates and insert a column next to the field which will give the no: of occurences (duplicates) of the field within the file.

Could somebody please help me with the syntax for this requirement?

Thanks in advance,
Simi

I have added this query to the wrong forum accidentally. Not sure how to move it to DFSORT forum now. Could any of the moderators help please?

Many Thanks,
Simi

Simi,

It's not clear what you want to do. Please show an example of the records in your input file (relevant fields only) and what you expect for output. Explain the "rules" for getting from input to output. Give the starting position, length and format of each relevant field. Give the RECFM and LRECL of the input files.

Also, run this job and show the //SYSOUT messages you receive, so I can see what level you're at:

Code:

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