uthami,

You can do file comparison using the JOIN feature available in SyncSort. But it's not quite clear what exactly you're expecting in output here. Please provide a few more details.

1)RECFM/LRECL of input as well as output files
2)Starting position and length of key field in the input files.
3)Do you have duplicates in the key field for input-1?
4)Do you have duplicates in the key field for input-2?
5)If matched, what fields you want in the output and from which files?

It would be better if you can provide some sample records from both the input files and the expected output using "Code" tags.
