GENERIC FILE TYPE MODULE

Hi,

I'm programming a game that involves a large number of 'objects' that need to be

saved at a DB. I don't want to use SQL or similar, so I have written a module
with a key (word) that alows me to read/write/erase records from the file
indexing
only with that key.
The problem is that as I need 10 different objects, I need a different Unit for
each
file type. My question is that if it is possible to make a generic Unit:

    Unit BD_GENERIC
    TYPE Generic_File=File Of GENERIC_DATA
(.....)

Please, e-mail for your suggestions.
Thanx.
