[Clp] Choose pivot variable to enter basic

[Paulo Jose da Silva e Silva]

Sure,

Take a look at  dualPivotResult (for the dual simplex)

http://coral.ie.lehigh.edu/coin/COIN/Osi/Doc/html/classOsiSimplexInterface.html#z89_7

and primalPivotResult

http://coral.ie.lehigh.edu/coin/COIN/Osi/Doc/html/classOsiSimplexInterface.html#z89_6

and the pivot functions (for general pivot)

http://coral.ie.lehigh.edu/coin/COIN/Osi/Doc/html/classOsiSimplexInterface.html#z89_5

from the OSI interface.
