>I have isolated some class definitions into .app files to allow me to isolate code functionality to a library. When I instantiate an object using code like the following:

If I do CLEAR ALL it release the .app file, but I can't really do that in the middle of my program! How can I get my VFP program to let go of the .app file?

Did you try RELEASE PROGRAM myAppName ?
