How to declare a variable to be public only to the other class modules in the project

Hi
I'm trying to build a simple database servises object,that includes several classes, and one of the classes is database preparation class wich prepepres the database and opens it, and it uses the variable DB as database, to contain the reference to the opened database.
now the question is to declare the DB variable so it will be available only for the classes included in the contained project,meaning only the classes in the project, that refere to DB for the services they provide.
actually,I could declare DB as public, but then,I expose DB to whichever using the classliberary I've created.
I'm trying to find something equivalent to the Friend declaration of procedures, but for variables,I've tried enforcing friend with the DB declaration, but it didn't work.

any Ideas??????
pls help(I'm quite novice with this stuff...)
Thank you all in advance

Add a module to your project and declare a variable as public. That's all.

Thanx

So simple....
It works!
