Bill,

First let me say that CLOSE DATABASE only works for the current database, that is the one that has been set to current with iehter the SET DATABASE TO command or the database combo in the standard toolbar. CLOSE DATABASE ALL does not close all dbc's, it closes all tables in the current data session.

Secondly the Project will open databases on you in the background, so before you MODI PROJ make sure set exclusive is ON. If you need to close the project, then close each database that is open. You can then, either OPEN DATABASE MyDBC EXCLUSIVE or SET EXCLUSIVE ON and OPEN DATABASE MyDbc.
