Hi all: I have a question about extracting the subfields from the 650 in the proper order. Basically, I have a number of records that contain 650s with $x Periodicals. I need to modify the subfield from x to v. The problem I am running into is that I don't know how to keep the subfields in the proper order. I have some records that have 650 $a $x $y $x and others that have 650 $a $x $x. It is this last $x that I need to change to a $v. Can someone offer some advise on modifying subfields that need to stay in the order found in the record? Thanks. Michael
