Hi all, I have two text files I need to compare: Every file contains a "converted" list of records separated by proper prefix: <z:row First_Name='aaa' Last_Name='bbb' Country =' ' Age=' ' I need to check File A (Source) and File B (Dest) and do the following: check line by line if record is equal (so check First Name, Last Name, Country, Age). If Equal - do nothing If different or doesn't exist, ADD at bottom of Dest file. I did it with IF cycle: Func _merge($user) $DBf
