I have 2 FLAT files, FILE1(rec length 500) & FILE2(rec length 200). I need to compare the 2 files, and if a match is found, write into 3rd file. How do i do it via JCL & program ? I need to take duplicates also into consideration.

Kindly excuse for posting onto incorrect TOPIC.

Depending on exactly what your records look like and what you want to do, you can use some variation of the "Create files with matching and non-matching records" Smart DFSORT Trick at:

http://www.ibm.com/servers/storage/support/software/sort/mvs/tricks/

Note that you'll need to expand the 200 byte records to 500 byte records (500:X) in order to SPLICE them.
