Yes I understand that, but that is why you will write code in the BeforeOpenTables event and change the Database there like this:

This.Cursor1.Database = Goapp.cPath + "MyData.dbc" &&Goapp.cPath stores the path to the DB
This.Cursor2.Database = Goapp.cPath + "MyOtherData.dbc"
This.Cursor3.Database = "c:\Test.dbc"
This.Cursor4.Database = "d:\op_serv.dbc"
