Hi,
This is the one way that i know,i have two files with matching records in both files. I have to get only matching records present in both files to the new file
Code: Select all
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.
