I was going to print a list here of all the files but thought better of it. There are a BUNCH of them. Instead I'll give you the command to get a list of files that you want.
Code:
find . -iname "*.php" | xargs grep "b_address" -l
You will need to be in the top directory of your store and it will recursively search through all the subdirectories from where you are.
This command will show only the PHP files and you probably also want to do one for "*.tpl" to get the templates as well.
The "-l" at the end suppresses the output of the matching text so you can remove that if you want to see the output.
Hope this helps. -I also would like to have JUST ONE MORE address line!!!

Richard
