File 1 is a Master File which contains the Key field locates @ position 13 and its length is 20 characters.
File 2 is an extract file from other source, where the Key fields locates @ position 190 and key length is 20 characters.
Both the files should process thru a single programs which take only the Key field from both the files.
I would like to write a SORT card, such that,
Take Key from File 2 and search for its existence in File 1
If it finds, I would like to remove it,
If not found write the record onto temporary file and then send it as an input to the above said program.
As the File 2 contains millions of records, it is wise enough to remove the unnecessary records before it goes thru the program.
