Add 006 and 007 tags to records?

Hello-

I am working on a shell script that will process the MARC records that represent items from our e-serials management database, and the thing I am stuck on is adding brand new 006 and 007 fixed field tags to each record. I am using the marcedit.pl fieldaddtobeg function, but it corrupts the records and makes them unparseable.

Is there a quick and easy way to do this within a script? (I know Perl works best with MARC but I am open to any suggestions).

Thank you!!
