Not a table data dictionary per se; the table definitions are stored
in a cryptic and undocumented form in the systems tables MSysObjects
and others. You can use Tools... Analyze... Documenter to generate a
report containing the information which would be in a proper data
dictionary, or you can use DAO or ADO code in VBA to open the
tabledefs collection, loop through the tables, and loop through the
fields in each table, and build your own.
