this should work, although you have to make sure that this data module
is the first contact of your application with IBO when the program
starts. If you want to really make sure, then add "MainDataModule"
(the name of the unit that contains the initialization section above)
as the first unit in your project's uses clause, or at least as high
as possible in the unit list.

If you want to use a particular version of fbclient.dll (let's say the
version in your application folder) then you might want to qualify the
file name, as in:

IB_Constants.IB_GDS32 := ExtractFilePath(ParamStr(0)) +

Using the unqualified name puts you in the hands of Windows'
LoadLibrary algorithm, which might or might not be what you want and
is a topic of its own.
