Is there a quicker way to add rows to the Index Code table rather than right-click and Insert Row for each new row. I often need to make over 100 part entries at a time. Thanks

If you use this file as a starting point, you can do it all in notepad then import the dbcodes.dat into the prj and it will create the index code table for you.

Thanks Matt, am I then able to somehow append those rows from the new imported dbcode table to an existing dbcode table in my .cat file?

It creates a new table when you import it, but I would think you should be able to copy and paste it from one table to another.
