Compare two datasets & write matching records to output

kavi1234 · Post by **kavi1234** » Mon Aug 31, 2015 3:45 pm

Hi all,

I have two datasets,
(i) first dataset contains 4 lakh records in the format:
100563gh
100564gb
100578gk
(ii)second dataset contains 46lakh records in the format:
100889hk
100895lg
100961pg

I want to compare these two datasets and find matched and unmatched records.

Please someone guide me to do this.

Thank you.

If you really want to do this in COBOL, ensure the files are in sequence on the key, and implement a "two-file match" program.

It is much easier using SORT's JOINKEYS, where all the coding has been done for you and you just use control cards to apply it.

How can i perform this so that

"This method is extremely flexible because the duplicates don't have to be in the same row in both data sets. The duplicates can be anywhere within the data set and this function will still find them."
