[Osi] regarding complete basis information

Hello all,
             I am using OsiClpSolverInterface to solve a simple LP of the
form
Ax<=b
l<=x<=u

where A is m*n matrix, b is m*1 vector, and, l & u  are lower and upper
bound vectors on x. I want to convert it to the form Cx=d, x>=0 and then
get its basic and non basic index information at optimal.
 si->getBasics(index) probably doesn't treat l<=x<=u as constraints  and
hence basis matrix has no information regarding them.  I want the bound
constraints inside basis matrix.

Regards,
Mouli
