Dear Djamel and Flemming,
Thanks for the additional info...I was missing the maing Db stuff.
However.... (running on rcas, I get the same response running at home
with the brat current as of this afternoon):
********************************************

brat [0] BrMainDb *mainDb = new BrMainDb::Instance()
Error: Symbol BrMainDb::Instance is not defined in current scope
FILE:/tmp/fileudpOe8_cint LINE:1
Error: type BrMainDb::Instance not defined FILE:/tmp/fileudpOe8_cint LINE:1
*** Interpreter error recovered ***
brat [1]
Do I need to do something special before creating the BrMainDb instance?
