Do you know GExperts? it's a free IDE enhancement with lots of useful
functions. Amongst them is "Project dependencies": you select a unit
from your project and a little tool shows you all units used by that,
*even indirectly!* (that is unita uses unitb which uses unitc, you'll still
see unitc watching unita).

you can get it from

you're right, the "bad" unit is actually DBTables, not DB. When your app
really uses the BDE, sooner or later it has to call dbiInit (the BDE
initialization api). This on gets called by TSession.InitializeBDE, which
gets called by TSession.StartSession.

a plain way to find out if the BDE is used is to simply rename the BDE
directory. You'll then get an error message (BDE initialization failed)
when you run your app. (this should get you going, unless you have
dynamically created data modules that might still use BDE - in that case
you'd only get the error when you call that part of your app...)

when parsers parse, and compilers compile, then why don't objects object?
