Using matching logic:
perform following code until either of EOF is found.
EVALUATE TRUE
WHEN KEY1> KEY2
READ FILE2
WHEN KEY2> KEY1
READ FILE1
WHEN KEY1=KEY2
WRITE FILE3 (WHATEVER FORMAT YOU WANT)
READ FILE1
READ FILE 2
END-EVALUATE
You can perform above code until both EOF found, incase you
need to create another file for non matching records. for
matching records only performing until either of EOF will
work.
