This is the one way that i know,

Code:

Perform until eof-file1 or eof-file2

Start-loop:
READ file-1
READ file-2

Check-loop:
If first-file-record-key > second-file-record-key
   READ file-2
   Go to check-loop
else
   if first-file-record-key < second-file-record-key
      READ file-1
      Go to check-loop
   else
      WRITE to matching-record-file
            Go to start-loop
   end-if
end-if
end-perform.
