FOA paron me for asking but how much space does 7 empty tables
take?
anyway, to ur questions.
u can defenetly incorparte all the tables into the .DBC
but i think u may not understand it correcty the .dbc
is actually just another .dbf file that holds extra informtaion about the relations of all the tables + stored procedures etc.
VFP is not like access where all the database is stored in the mdb

again, the .CDXs are not part of the .dbc , the .dbc will hold info about them e.g. the name of the primery index.
also not only u can add tables to the DBC programatically u can create
it programatically as well
If one DBF

no

u can set realtions when designing the DBC u can also do this
the old fashioned way
