Description

U2_BFS()

Main Support Modules for OpenInsight's communication with the U2 databases.  

The BFS is architected to hide the fact that you are using a separate filing system.   This fiction works best when you are building forms against table.  The farther you get from this the more likely you are to use some of the supporting routines and exploit the full power offered by OpenInsightI for U2.
