You seem to be talking about apples and oranges. Access is a database
product and IDL is a data analysis product. Probably the easiest thing
to do is port the project to another database, not IDL. I'd recommend
MySQL -- stable, fast, free.

Yep, I know what you mean, but I think the thing should have been
originally written in IDL. It is just applying algorithms to
matrices. It was written by a guy who had no programming experience
and so he used access. It has grown to become ridiculously unwieldy,
whereas the algorithms are not that complex (but difficult to reverse
engineer from looking at the database/tables and queries).
