What is Sortxsum?

sortxsum is generally used to retrieve the records that were suppressed due to duplicates. In the JCL a DD statement SORTXSUM for the dataset to store the suppressed records due to duplicates and in the SYSIN XSUM should be used. There is a inter-link between sortxsum and xsum. Ex : SUM FIELDS=NONE,XSUM.

How do I delete duplicate records in Cobol?

If you will sort the file with an external sort prior to reading it in the cobol program you can remove the duplicates with the SORT keyword EQUALS. If you sort the file prior to the cobol program and do not drop duplicates then a simple IF statement and a save field will allow you to delete the dups.

How do you find duplicates in Cobol?

Open a COBOL program or a COBOL copybook with the COBOL Editor. Right-click and choose Duplicate Code Detection menu and Search duplicates in this file.

How do you remove duplicates in Photoshop?

I suggest adding a SEQNUM to the records during INREC processing, then SORT with SUM FIELDS=NONE to drop duplicates. Next, SORT based on the SEQNUM that was added and drop the SEQNUM during output processing. This gives the remaining records in the original order.

When to use XSUM in Syncsort?

2) XSUM should be used when you have a case where the records from input file A should be copied to file B without duplicate records, and the eliminated duplicate records should be saved in a file C. Here file C will be the file for the DD name SORTXSUM. Take note that XSUM is a unique feature of the SYNCSORT product ONLY.

Does DFSORT support the XSUM operand?

While DFSORT does not support the XSUM operand, DFSORT does provide the equivalent function and a lot more with the SELECT operator of ICETOOL. SELECT lets you put the records that are selected in the TO data set and the records that are not selected in the DISCARD data set.

What is the difference between sortxsum and XSUM?

Where XSUM means the dropped records are written in the dataset specified by SORTXSUM data set. SORTXSUM: Output file for a SORT or MERGE function. The records eliminated by SUM processing are written to the SORTXSUM DD.

Is it possible to combine XSUM and select in one step?

This cannot be done in one step, but SELECT (certainly the DFSORT version) can do all that XSUM does and more, in one function.
