Kipp,

     Hi:

     I am using Osi to build an OsiSolverInterface. When I create the linear
     program and use setBasisStatus it has absolutely no effect on the 
number
     of pivots that Clp does even if I start with an optimal basis. 
Perhaps I
     should be using setWarmStart?

     Is there any documentation, or are there any examples anywhere, on how
     to use either setWarmStart or setBasisStatus?

     Thanks
