[AccessD] Cycle thru All Tables in DB

I'm sure this is possible, but have never coded it.
I have 50 tables, each containing 50 fields.  Some of the fields contain
empty strings.  I need to cycle thru every table, and update all empty
strings to null.
 
Is there a way to cycle thru each table, and cycle thru each field
record by record, and update to null where necessary?
I want to avoid using specific table and field names.
 
Any ideas?
Thanks.
